Bidders are further urged to review sections 2-3 SUBCONTRACTS of the General Provisions. CAUTIONS This form will be used by the Agency to determine the percentage of work that the Bidder proposes to perform. Bidders are cautioned that failure to provide complete and correct information may result in rejection of the bid as non-responsive. Any bid that proposes performance of more than 50 percent of the work by subcontractors or otherwise to be preformed by forces other than the Bidder's own organization will be rejected as non-responsive. Specialty items of work that may be so designated by the Engineer on the "Contractor's Proposal" are not included in computing the percentage of work proposed to be performed by the Bidder. INSTRUCTIONS The Bidder shall set forth the name and location of business of each and every subcontractor whom the Bidder proposes to perform work or labor or render service in or about the work or improvement, and every subcontractor licensed as a contractor by the State of California whom the Bidder proposes to specially fabricate and install any portion of the work or improvement according to detailed drawings contained in the plans and specifications in excess of one-half of one percent (0.5%) of the Bidder's total bid or, in the case of bids or offers for the construction of streets and highways, including bridges, in excess of one-half of one percent (0.5%) or ten thousand dollars ($10,000) whichever is greater.

The Designation of Subcontractors form must be submitted as a part of the Bidder's sealed bid. Failure to provide complete and correct information may result in rejection of the bid as non- responsive. Suppliers of materials from sources outside the limits of work are not subcontractors. The value of materials and transport of materials from sources outside the limits of work, as shown on the plans, shall be assigned to the Contractor or the Subcontractor as the case may be, that the Bidder proposes as installer of said materials. The value of material incorporated in any Subcontractor- installed bid item that is supplied by the Bidder shall be included as a part of the work that the Bidder proposes to be performed by the Subcontractor installing said item. When a Subcontractor has a Carlsbad business license, the number must be entered on the proper form. If the Subcontractor does not have a valid business license, enter "NONE" in the appropriate space. When the Bidder proposes using a Subcontractor to construct or install less than 100 percent of a bid item, the Bidder shall attach an explanation sheet to the Designation of Subcontractor form. The explanation sheet shall clearly apprise the City of the specific facts that show the Bidder proposes to perform no less than fifty percent (50%) of the work with its own forces. Determination of the subcontract amounts for purposes of award of the contract shall be determined by the City Council in conformance with the provisions of the contract documents and the various supplemental provisions. The decision of the City Council shall be final.

The ACORD name and logo are registered marks of ACORD POLICY NUMBER: DTE -C07989R381 COMMERCIAL GENERAL LIABILITY THIS ENDORSEMENT CHANGES THE POLICY. PLEASE READ IT CAREFULLY BLANKET ADDITIONAL INSURED (CONTRACTORS) This endorsement modifies insurance provided under the following: COMMERCIAL GENERAL LIABILITY COVERAGE PART 1. WHO IS AN INSURED - (Section II) Is amended to Include any person or organization that you agree in a "written contract requiring insurance" to include as an additional Insured on this Cover- age Part, but: a) Only with respect to liability for "bodily injury", "property damage" or "personal injury"; and b) If, and only to the extent that, the injury or damage is caused by acts or omissions of you or your subcontractor in the performance of "your work" to which the "written contract requiring insurance" applies. The person or organization does not qualify as an additional insured with respect to the independent acts or omissions of such person or organization. 2. The insurance provided to the additional insured by this endorsement is limited as follows: a) In the event that the Limits of Insurance of this Coverage Part shown in the Declarations exceed the limits of liability required by the "written contract requiring insurance", the in- surance provided to the additional insured shall be limited to the limits of liability re- quired by that "written contract requiring in- surance". This endorsement shall not in- crease the limits of insurance described in Section III ~ Limits Of Insurance. b) The insurance provided to the additional in- sured does not apply to "bodily injury", "prop- erty damage" or "personal injury" arising out of the rendering of, or failure to render, any professional architectural, engineering or sur- veying services, including: I. The preparing, approving, or failing to prepare or approve, maps, shop draw- ings, opinions, reports, surveys, field or- ders or change orders, or the preparing, approving, or failing to prepare or ap- prove, drawings and specifications; and ii. Supervisory, inspection, architectural or engineering activities. c) The insurance provided to the additional in- sured does not apply to "bodily injury" or "property damage" caused by "your work" and included in the "products-completed op- erations hazard" unless the "written contract requiring insurance" specifically requires you to provide such coverage for that additional insured, and then the insurance provided to the additional insured applies only to such "bodily injury" or "property damage" that oc- curs before the end of the period of time for which the "written contract requiring insur- ance" requires you to provide such coverage or the end of the policy period, whichever is earlier. 3. The Insurance provided to the additional insured by this endorsement is excess over any valid and collectible "other insurance", whether primary, excess, contingent or on any other basis, that is available to the additional insured for a loss we cover under this endorsement. However, if the "written contract requiring insurance" specifically requires that this insurance apply on a primary basis or a primary and non-contributory basis, this insurance is primary to "other Insurance" available to the additional insured which covers that person or organization as a named insured for such loss, and we will not share with that "other insurance". But the insurance provided to the additional insured by this endorsement still is excess over any valid and collectible "other in- surance", whether primary, excess, contingent or on any other basis, that is available to the addi- tional insured when that person or organization Is an additional insured under such "other insur- ance". 4. As a condition of coverage provided to the additional insured by this endorsement: a) The additional insured must give us written notice as soon as practicable of an "occur- rence" or an offense which may result in a claim. To the extent possible, such notice should include: CG 02 46 08 05 © 2005 The St. Paul Travelers Companies, Inc.Page 1 of 2 COMMERCIAL GENERAL LIABILITY i. How, when and where the "occurrence" or offense took place; II. The names and addresses of any injured persons and witnesses; and III. The nature and location of any injury or damage arising out of the "occurrence" or offense. b) If a claim is made or "suit" is brought against the additional insured, the additional insured must: I. Immediately record the specifics of the claim or "suit" and the date received; and II. Notify us as soon as practicable. The additional insured must see to it that we receive written notice of the claim or "suit" as soon as practicable. c) The additional insured must immediately send us copies of all legal papers received in connection with the claim or "suit", cooperate with us in the investigation or settlement of the claim or defense against the "suit", and otherwise comply with all policy conditions. d) The additional insured must tender the de- fense and indemnity of any claim or "suit" to any provider of "other insurance" which would cover the additional insured for a loss we cover under this endorsement. However, this condition does not affect whether the insur- ance provided to the additional insured by this endorsement is primary to "other Insur- ance" available to the additional Insured which covers that person or organization as a named insured as described in paragraph 3. above. 5. The following definition Is added to SECTION V. - DEFINITIONS: "Written contract requiring insurance" means that part of any written contract or agreement under which you are required to include a person or organization as an additional in- sured on this Coverage Part, provided that the "bodily injury" and "property damage" oc- curs and the "personal injury" is caused by an offense committed: a. After the signing and execution of the contract or agreement by you; b. While that part of the contract or agreement is in effect; and c. Before the end of the policy period.

Award and execution of Contract will be as provided for in the Specifications, Instruction to Bidders, or Notice Inviting Bids. 2-2 ASSIGNMENT. No Contract or portion thereof may be assigned without consent of the Board, except that the Contractor may assign money due or which will accrue to it under the Contract. If given written notice, such assignment will be recognized by the Board to the extent permitted by law. Any assignment of money shall be subject to all proper withholdings in favor of the Agency and to all deductions provided for in the Contract. All money withheld, whether assigned or not, shall be subject to being used by the Agency for completion of the Work, should the Contractor be in default. 2-3 SUBCONTRACTS. 2-3.1 General. Each Bidder shall comply with the Chapter of the Public Contract Code including Sections 4100 through 4113. The following excerpts or summaries of some of the requirements of this Chapter are included below for information: The Bidder shall set forth in the Bid, as provided in 4104: "(a) The name and location of the place of business of each subcontractor who will perform work or labor or render service to the prime contractor in or about the construction of the work or improvements, or a subcontractor licensed by the State of California who, under subcontract to the prime contractor, specially fabricates and installs a portion of the work or improvement according to detailed drawings contained in the plans and specifications, in an amount in excess of one-half of 1 percent of the prime contractor's total bid, or, in the case of bids or offers for the construction of streets or highways, including bridges, in excess of one-half of 1 percent of the prime contractor's total bid or ten thousand dollars ($10,000), whichever is greater." "(b) The portion of the work which will be done by each such subcontractor under this act. The prime contractor shall list only one subcontractor for each such portion as is defined by the prime contractor in his bid." If the Contractor fails to specify a Subcontractor, or specifies more than one Subcontractor for the same portion of the work to be performed under the Contract (in excess of one-half of 1 percent of the Contractor's total Bid), the Contractor shall be qualified to perform that portion itself, and shall perform that portion itself, except as otherwise provided in the Code. As provided in Section 4107, no Contractor whose Bid is accepted shall substitute any person as Subcontractor in place of the Subcontractor listed in the original Bid, except for causes and by procedures established in Section 4107.5. This section provides procedures to correct a clerical error in the listing of a Subcontractor. Section 4110 provides that a Contractor violating any of the provisions of the Chapter violates the Contract and the Board may exercise the option either to cancel the Contract or assess the Contractor a penalty in an amount of not more than 10 percent of the subcontract involved, after a public hearing. Should the Contractor fail to adhere to the provisions requiring the Contractor to complete 50 percent of the contract price with its own organization, the Agency may at its sole discretion elect Revised 11/13/09 Contract No.5507-1 Page 48 of 98 to cancel the contract or deduct an amount equal to 10 percent of the value of the work performed in excess of 50 percent of the contract price by other than the Contractor's own organization. The Board shall be the sole body for determination of a violation of these provisions. In any proceedings under this section, the prime contractor shall be entitled to a public hearing before the Board and shall be notified ten (10) days in advance of the time and location of said hearing. The determination of the City Council shall be final. 2-3.2 Additional Responsibility. The Contractor shall give personal attention to the fulfillment of the Contract and shall keep the Work under its control. The Contractor shall perform, with its own organization, Contract work amounting to at least 50 percent of the Contract Price except that any designated "Specialty Items" may be performed by subcontract, and the amount of any such "Specialty Items" so performed may be deducted from the Contract Price before computing the amount required to be performed by the Contractor with its own organization. "Specialty Items" will be identified by the Agency in the Bid or Proposal. Where an entire item is subcontracted, the value of work subcontracted will be based on the Contract Unit Price. When a portion of an item is subcontracted, the value of work subcontracted will be based on the estimated percentage of the Contract Unit Price. This will be determined from information submitted by the Contractor, and subject to approval by the Engineer. Before the work of any Subcontractor is started, the Contractor shall submit to the Engineer for approval a written statement showing the work to be subcontracted giving the name and business of each Subcontractor and description and value of each portion of the work to be so subcontracted. 2-3.3 Status of Subcontractors. Subcontractors shall be considered employees of the Contractor, and the Contractor shall be responsible for their work. 2-4 CONTRACT BONDS. Before execution of the Contract, the Bidder shall file surety bonds with the Agency to be approved by the Board in the amounts and for the purposes noted below. Bonds issued by a surety, who is authorized to issue bonds in California, and whose bonding limitation shown in said circular is sufficient to provide bonds in the amount required by the Contract shall be deemed to be approved unless specifically rejected by the Agency. Bonds from all other sureties shall be accompanied by all of the documents enumerated in Code of Civil Procedure 995.660 (a). The Bidder shall pay all bond premiums, costs, and incidentals. Each bond shall incorporate, by reference, the Contract and be signed by both the Bidder and Surety and the signature of the authorized agent of the Surety shall be notarized. The Contractor shall provide a faithful performance/warranty bond and payment bond (labor and materials bond) for this contract. The faithful performance/warranty bond shall be in a sum not less than one hundred percent of the total amount payable by the terms of this contract. The Contractor shall provide bonds to secure payment of laborers and materials suppliers in a sum not less than one hundred percent of the total amount payable by the terms of this contract. Both bonds shall extend in full force and effect and be retained by the Agency during this project until they are released according to the provisions of this section. The faithful performance/warranty bond will be reduced to 25 percent of the original amount 30 days after recordation of the Notice of Completion and will remain in full force and effect for the one year warranty period and until all warranty repairs are completed to the satisfaction of the Engineer. The bonds to secure payment of laborers and materials suppliers shall be released six months plus 30 days after recordation of the Notice of Completion if all claims have been paid. Revised 11/13/09 Contract No.5507-1 Page 49 of 98 All bonds are to be placed with a surety insurance carrier admitted and authorized to transact the business of insurance in California and whose assets exceed their liabilities in an amount equal to or in excess of the amount of the bond. The bonds are to contain the following documents: 1) An original, or a certified copy, of the un-revoked appointment, power of attorney, by laws, or other instrument entitling or authorizing the person who executed the bond to do so. 2) A certified copy of the certificate of authority of the insurer issued by the insurance commissioner. If the bid is accepted, the Agency may require a financial statement of the assets and liabilities of the insurer at the end of the quarter calendar year prior to 30 days next preceding the date of the execution of the bond. The financial statement shall be made by an officer's certificate as defined in Section 173 of the Corporations Code. In the case of a foreign insurer, the financial statement may be verified by the oath of the principal officer or manager residing within the United States. Should any bond become insufficient, the Contractor shall renew the bond within 10 days after receiving notice from the Agency. Should any Surety at any time be unsatisfactory to the Board, notice will be given the Contractor to that effect. No further payments shall be deemed due or will be made under the contract until a new Surety shall qualify and be accepted by the Board. Changes in the Work or extensions of time, made pursuant to the Contract, shall in no way release the Contractor or Surety from its obligations. Notice of such changes or extensions shall be waived by the Surety. 2-5 PLANS AND SPECIFICATIONS. 2-5.1 General.

The Engineer and any authorized representatives shall at all times have access to the Work during its construction at shops and yards as well as the project site. The Contractor shall provide every reasonable facility for ascertaining that the materials and workmanship are in accordance with these specifications. Inspection of the Work shall not relieve the Contractor of the obligation to fulfill all conditions of the Contract. Revised 11/13/09 Contract No.5507-1 Page 55 of 98 SECTION 3 - CHANGES IN WORK 3-1 CHANGES REQUESTED BY THE CONTRACTOR. 3-1.1 General. Changes in the Plans and Specifications, requested in writing by the Contractor, which do not materially affect the Work and which are not detrimental to the Work or to the interests of the Agency, may be granted by the Engineer. Nothing herein shall be construed as granting a right to the Contractor to demand acceptance of such changes. 3-1.2 Payment for Changes Requested by the Contractor. If such changes are granted, they shall be made at a reduction in cost or no additional cost to the Agency. 3-2 CHANGES INITIATED BY THE AGENCY. 3-2.1 General. The Agency may change the Plans, Specifications, character of the work, or quantity of work provided the total arithmetic dollar value of all such changes, both additive and deductive, does not exceed 50 percent of the Contract Price. Should it become necessary to exceed this limitation, the change shall be by written Supplemental Agreement between the Contractor and Agency, unless both parties agree to proceed with the change by Change Order. Change Orders shall be in writing and state the dollar value of the change or established method of payment, any adjustment in contract time of completion, and when negotiated prices are involved, shall provide for the Contractor's signature indicating acceptance. 3-2.2 Payment. 3-2.2.1 Contract Unit Prices. If a change is ordered in an item of work covered by a Contract Unit Price, and such change does not involve substantial change in character of the work from that shown on the Plans or specified in the Specifications, then an adjustment in payment will be made. This adjustment will be based upon the increase or decrease in quantity and the Contract Unit Price. If the actual quantity of an item of work covered by a Contract Unit Price and constructed in conformance with the Plans and Specifications varies from the Bid quantity by 50 percent or less, payment will be made at the Contract Unit Price. If the actual quantity of said item of work varies from the Bid quantity by more than 50 percent, payment will be made per Section 3-2.2.2 or 3-2.2.3 as appropriate. If a change is ordered in an item of work covered by a Contract Unit Price, and such change does involve a substantial change in the character of the work from that shown on the Plans or specified in the Specifications, an adjustment in payment will be made per Section 3-2.4. 3-2.2.2 Increases of More Than 50 Percent. Should the actual quantity of an item of work covered by a Contract Unit Price and constructed in conformance with the Plans and Specifications, exceed the Bid quantity by more than 50 percent, payment for the quantity in excess of 150 percent of the Bid quantity will be made on the basis of an adjustment in the Contract Unit Price mutually agreed to by the Contractor and the Agency, or at the option of the Engineer, on the basis of Extra Work per Section 3-3. The Extra Work per Section 3-3, basis of payment, shall not include fixed costs. Fixed costs shall be deemed to have been recovered by the Contractor through payment for 150 percent of the Bid quantity at the Contract Unit Price. 3-2.2.3 Decreases of More Than 50 Percent. Should the actual quantity of an item of work covered by a Contract Unit Price, and constructed in conformance with the Plans and Specifications, be less than 50 percent of the Bid quantity, an adjustment in payment will not be made unless so requested Revised 1 1/13/09 Contract No.5507-1 Page 56 of 98 in writing by the Contractor. If the Contractor so requests, payment will be made on the basis of an adjustment in the Contract Unit Price mutually agreed to by the Contractor and the Agency, or at the option of the Engineer, on the basis of Extra Work per Section 3-3; however, in no case will payment be less than would be made for the actual quantity at the Contract Unit Price nor more than would be made for 50 percent of the Bid quantity at the Contract Unit Price. 3-2.3 Stipulated Unit Prices. Stipulated Unit Prices are unit prices established by the Agency in the Contract Documents as distinguished from Contract Unit Prices submitted by the Contractor. Stipulated Unit Prices may be used for the adjustment of Contract changes when so specified in the Special Provisions. 3-2.4 Agreed Prices. Agreed Prices are prices for new or unforeseen work, or adjustments in Contract Unit Prices per Section 3-2.2, established by mutual agreement between the Contractor and the Agency. If mutual agreement can not be reached, the Engineer may direct the Contractor to proceed on the basis of Extra Work in accordance per Section 3-3, except as otherwise specified in Sections 3-2.2.2 and 3-2.2.3. 3.2.4.1 Schedule of Values. Prior to construction, Contractor shall provide a schedule of values for all lump sum bid items that shall be used for the purpose of progress payments. The prices shall be valid for the purpose of change orders to the project. 3.2.5 Eliminated Items. Should any Bid item be eliminated in its entirety, payment will be made to the Contractor for its actual costs incurred in connection with the eliminated item prior to notification in writing from the Engineer so stating its elimination. If material conforming to the Plans and Specifications is ordered by the Contractor for use in the eliminated item prior to the date of notification of elimination by the Engineer, and if the order for that material can not be canceled, payment will be made to the Contractor for the actual cost of the material. In this case, the material shall become the property of the Agency. Payment will be made to the Contractor for its actual costs for any further handling. If the material is returnable, the material shall be returned and payment will be made to the Contractor for the actual cost of charges made by the supplier for returning the material and for handling by the Contractor. Actual costs, as used herein, shall be computed on the basis of Extra Work per Section 3-3. 3-3 EXTRA WORK. 3-3.1 General. New or unforeseen work will be classified as "extra work" when the Engineer determines that it is not covered by Contract Unit Prices or stipulated unit prices. 3-3.2 Payment. 3-3.2.1 General. When the price for the extra work cannot be agreed upon, the Agency will pay for the extra work based on the accumulation of costs as provided herein. 3-3.2.2 Basis for Establishing Costs. (a) Labor. The costs of labor will be the actual cost for wages of workers performing the extra work at the time the extra work is done, plus employer payments of payroll taxes, workers compensation insurance, liability insurance, health and welfare, pension, vacation, apprenticeship funds, and other direct costs, resulting from Federal, State, or local laws, as well as assessments or benefits required by lawful collective bargaining agreements. Revised 11/13/09 Contract No.5507-1 Page 57 of 98 The use of a labor classification which would increase the extra work cost will not be permitted unless the Contractor establishes the necessity for such additional costs. Labor costs for equipment operators and helpers shall be reported only when such costs are not included in the invoice for equipment rental. The labor cost for foremen shall be proportioned to all of their assigned work and only that applicable to extra work will be paid. Nondirect labor costs, including superintendence, shall be considered part of the markup of Section 3-3.2.3 (a). (b) Materials. The cost of materials reported shall be at invoice or lowest current price at which such materials are locally available and delivered to the job site in the quantities involved, plus sales tax, freight, and delivery. The Agency reserves the right to approve materials and sources of supply, or to supply materials to the Contractor if necessary for the progress of the Work. No markup shall be applied to any material provided by the Agency. (c) Tool and Equipment Rental. No payment will be made for the use of tools which have a replacement value of $200 or less. Regardless of ownership, the rates and right-of-way delay factors to be used in determining rental and delay costs shall be the edition of the, "Labor Surcharge and Equipment Rental Rates" published by CALTRANS, current at the time of the actual use of the tool or equipment. The right-of- way delay factors therein shall be used as multipliers of the rental rates for determining the value of costs for delay to the Contractor and subcontractors, if any. The labor surcharge rates published therein are not a part of this contract. The rental rates paid shall include the cost of fuel, oil, lubrication, supplies, small tools, necessary attachments, repairs and maintenance of any kind, depreciation, storage, insurance, and all incidentals. Necessary loading and transportation costs for equipment used on the extra work shall be included. If equipment is used intermittently and, when not in use, could be returned to its rental source at less expense to the Agency than holding it at the Work site, it shall be returned, unless the Contractor elects to keep it at the Work site, at no expense to the Agency. All equipment shall be acceptable to the Engineer, in good working condition, and suitable for the purpose for which it is to be used. Manufacturer's ratings and approved modifications shall be used to classify equipment and it shall be powered by a unit of at least the minimum rating recommended by the manufacturer. The reported rental time for equipment already at the Work site shall be the duration of its use on the extra work. This time begins when equipment is first put into actual operation on the extra work, plus the time required to move it from its previous site and back, or to a closer site. (d) Other Items. The Agency may authorize other items which may be required on the extra work, including labor, services, material, and equipment. These items must be different in their nature from those required for the Work, and be of a type not ordinarily available from the Contractor or Subcontractors. Invoices covering all such items in detail shall be submitted with the request for payment. Revised 11/13/09 Contract No.5507-1 Page 58 of 98 (e) Invoices. Vendors' invoices for material, equipment rental and other expenditures shall be submitted with the request for payment. If the request for payment is not substantiated by invoices or other documentation, the Agency may establish the cost of the item involved at the lowest price which was current at the time of the report. 3-3.2.3 Markup. (a) Work by Contractor. The following percentages shall be added to the Contractor's costs and shall constitute the markup for all overhead and profits: 1) Labor ................................... 20 2) Materials ............................. 15 3) Equipment Rental ................... 15 4) Other Items and Expenditures .. 15 To the sum of the costs and markups provided for in this section, 1 percent shall be added as compensation for bonding. (b) Work by Subcontractor. When all or any part of the extra work is performed by a Subcontractor, the markup established in Section 3-3.2.3(a) shall be applied to the Subcontractor's actual cost of such work. A markup of 10 percent on the first $5,000 of the subcontracted portion of the extra work and a markup of 5 percent on work added in excess of $5,000 of the subcontracted portion of the extra work may be added by the Contractor. 3-3.3 Daily Reports by Contractor. When the price for the extra work cannot be agreed upon, the Contractor shall submit a daily report to the Engineer on forms approved by the Agency. Included are applicable delivery tickets, listing all labor, materials, and equipment involved for that day, and other services and expenditures when authorized. Payment for extra work will not be made until such time that the Contractor submits completed daily reports and all supporting documents to the Engineer. Failure to submit the daily report by the close of the next working day may waive any rights for that day. An attempt shall be made to reconcile the report daily, and it shall be signed by the Engineer and the Contractor. In the event of disagreement, pertinent notes shall be entered by each party to explain points which cannot be resolved immediately. Each party shall retain a signed copy of the report. Reports by Subcontractors or others shall be submitted through the Contractor. The report shall: 1 . Show names of workers, classifications, and hours worked. 2. Describe and list quantities of materials used. 3. Show type of equipment, size, identification number, and hours of operation, including loading and transportation, if applicable. 4. Describe other services and expenditures in such detail as the Agency may require. 3-4 CHANGED CONDITIONS. The Contractor shall promptly notify the Engineer of the following Work site conditions (hereinafter called changed conditions), in writing, upon their discovery and before they are disturbed: 1. Subsurface or latent physical conditions differing materially from those represented in the Contract; 2. Unknown physical conditions of an unusual nature differing materially from those ordinarily encountered and generally recognized as inherent in work of the character being performed; and Revised 1 1/13/09 Contract No.5507-1 Page 59 of 98 3. Material differing from that represented in the Contract which the Contractor believes may be hazardous waste, as defined in Section 25117 of the Health and Safety Code, that is re- quired to be removed to a Class I, Class II, or Class III disposal site in accordance with provisions of existing law. The Engineer will promptly investigate conditions which appear to be changed conditions. If the Engineer determines that conditions are changed conditions and they will materially affect performance time, the Contractor, upon submitting a written request, will be granted an extension of time subject to the provisions of 6-6. If the Engineer determines that the conditions do not justify an adjustment in compensation, the Contractor will be notified in writing. This notice will also advise the Contractor of its obligation to notify the Engineer in writing if the Contractor disagrees. The Contractor's failure to give notice of changed conditions promptly upon their discovery and before they are disturbed shall constitute a waiver of all claims in connection therewith. The Contractor shall not be entitled to the payment of any additional compensation for any act, or failure to act, by the Engineer, including failure or refusal to issue a change order, or for the happening of any event, thing, occurrence, or other cause, unless the Contractor shall have first given the Engineer due written notice of potential claim as hereinafter specified. Compliance with this section shall not be required as a prerequisite to notice provisions in Section 6-7.3 Contract Time Accounting, nor to any claim that is based on differences in measurement or errors of computation as to contract quantities. The written notice of potential claim for changed conditions shall be submitted by the Contractor to the Engineer upon their discovery and prior to the time that the Contractor performs the work giving rise to the potential claim. The Contractor's failure to give written notice of potential claim for changed conditions to the agency upon their discovery and before they are disturbed shall constitute a waiver of all claims in connection therewith. The Contractor shall provide the City with a written document containing a description of the particular circumstances giving rise to the potential claim, the reasons for which the Contractor believes additional compensation may be due and nature of any and all costs involved within 20 working days of the date of service of the written notice of potential claim for changed conditions. Verbal notifications are disallowed. The potential claim shall include the following certification relative to the California False Claims Act, Government Code Sections 12650-12655. "The undersigned certifies that the above statements are made in full cognizance of the California False Claims Act, Government Code Sections 12650-12655. The undersigned further understands and agrees that this potential claim, unless resolved, must be restated as a claim in response to the City's proposed final estimate in order for it to be further considered." By: Title: Date: Company Name: The Contractor's estimate of costs may be updated when actual costs are known. The Contractor shall submit substantiation of its actual costs to the Engineer within 20 working days after the affected work is completed. Failure to do so shall be sufficient cause for denial of any claim Revised 11/13/09 Contract No.5507-1 Page 60 of 98 subsequently filed on the basis of said notice of potential claim. It is the intention of this section that differences between the parties arising under and by virtue of the contract be brought to the attention of the Engineer at the earliest possible time in order that such matters be settled, if possible, or other appropriate action promptly taken. 3-5 DISPUTED WORK. The Contractor shall give the agency written notice of potential claim prior to commencing any disputed work. Failure to give said notice shall constitute a waiver of all claims in connection therewith. If the contractor and the agency are unable to reach agreement on disputed work, the Agency may direct the contractor to proceed with the work. Prior to proceeding with dispute resolution pursuant to Public Contract Code provisions specified hereinafter, the contractor shall attempt to resolve all disputes informally through the following dispute resolution chain of command: 1. Project Inspector 2. Construction Manager 3. Deputy City Engineer, Construction Management & Inspection 4. City Engineer 5. City Manager The Contractor shall submit a complete report within 20 working days after completion of the disputed work stating its position on the claim, the contractual basis for the claim, along with all documentation supporting the costs and all other evidentiary materials. At each level of claim or appeal of claim the City will, within 10 working days of receipt of said claim or appeal of claim, review the Contractor's report and respond with a position, request additional information or request that the Contractor meet and present its report. When additional information or a meeting is requested the City will provide its position within 10 working days of receipt of said additional information or Contractor's presentation of its report. The Contractor may appeal each level's position up to the City Manager after which the Contractor may proceed under the provisions of the Public Contract Code. The authority within the dispute resolution chain of command is limited to recommending a resolution to a claim to the City Manager. Actual approval of the claim is subject to the change order provisions in the contract. All claims by the contractor for $375,000 or less shall be resolved in accordance with the procedures in the Public Contract Code, Division 2, Part 3, Chapter 1, Article 1.5 (commencing with Section 20104) which is set forth below: ARTICLE 1.5 RESOLUTION OF CONSTRUCTION CLAIMS 20104.

(b) In any suit filed under Section 20104.4, the local agency shall pay interest at the legal rate on any arbitration award or judgment. The interest shall begin to accrue on the date the suit is filed in a court of law. Although not to be construed as proceeding under extra work provisions, the Contractor shall keep and furnish records of disputed work in accordance with Section 3-3. SECTION 4 - CONTROL OF MATERIALS 4-1 MATERIALS AND WORKMANSHIP. 4-1.1. General. All materials, parts, and equipment furnished by the Contractor in the Work shall be new, high grade, and free from defects. Quality of work shall be in accordance with the generally accepted standards. Material and work quality shall be subject to the Engineer's approval. Materials and work quality not conforming to the requirements of the Specifications shall be considered defective and will be subject to rejection. Defective work or material, whether in place or not, shall be removed immediately from the site by the Contractor, at its expense, when so directed by the Engineer. If the Contractor fails to replace any defective or damaged work or material after reasonable notice, the Engineer may cause such work or materials to be replaced. The replacement expense will be deducted from the amount to be paid to the Contractor. Revised 11/13/09 Contract No.5507-1 Page 63 of 98 Used or secondhand materials, parts, and equipment may be used only if permitted by the Specifications. 4-1.2 Protection of Work and Materials. The Contractor shall provide and maintain storage facilities and employ such measures as will preserve the specified quality and fitness of materials to be used in the Work. Stored materials shall be reasonably accessible for inspection. The Contractor shall also adequately protect new and existing work and all items of equipment for the duration of the Contract. The Contractor shall not, without the Agency's consent, assign, sell, mortgage, hypothecate, or remove equipment or materials which have been installed or delivered and which may be necessary for the completion of the Contract. 4-1.3 Inspection Requirements. 4-1.3.1 General. Unless otherwise specified, inspection is required at the source for such typical materials and fabricated items as bituminous paving mixtures, structural concrete, metal fabrication, metal casting, welding, concrete pipe manufacture, protective coating application, and similar shop or plant operations. Steel pipe in sizes less than 18 inches and vitrified clay and cast iron pipe in all sizes are acceptable upon certification as to compliance with the Specifications, subject to sampling and testing by the Agency. Standard items of equipment such as electric motors, conveyors, elevators, plumbing fixtures, etc., are subject to inspection at the job site only. Special items of equipment such as designed electrical panel boards, large pumps, sewage plant equipment, etc., are subject to inspection at the source, normally only for performance testing. The Specifications may require inspection at the source for other items not typical of those listed in this section. The Contractor shall provide the Engineer free and safe access to any and all parts of work at any time. Such free and safe access shall include means of safe access and egress, ventilation, lighting, shoring, dewatering and all elements pertaining to the safety of persons as contained in the State of California, California Code of Regulations, Title 8, Industrial Relations, Chapter 4, Division of Industrial Safety, Subchapter 4, Construction Safety Orders and such other safety regulations as may apply. Contractor shall furnish Engineer with such information as may be necessary to keep the Engineer fully informed regarding progress and manner of work and character of materials. Inspection or testing of the whole or any portion of the work or materials incorporated in the work shall not relieve Contractor from any obligation to fulfill this Contract. 4-1.3.2 Inspection of Materials Not Locally Produced. When the Contractor intends to purchase materials, fabricated products, or equipment from sources located more than 50 miles outside the geographical limits of the Agency, an inspector or accredited testing laboratory (approved by the Engineer), shall be engaged by the Contractor at its expense, to inspect the materials, equipment or process. This approval shall be obtained before producing any material or equipment. The inspector or representative of the testing laboratory shall judge the materials by the requirements of the Plans and Specifications. The Contractor shall forward reports required by the Engineer. No material or equipment shall be shipped nor shall any processing, fabrication or treatment of such materials be done without proper inspection by the approved agent. Approval by said agent shall not relieve the Contractor of responsibility for complying with the Contract requirements. 4-1.3.3 Inspection by the Agency. The Agency will provide all inspection and testing laboratory services within 50 miles of the geographical limits of the Agency. For private contracts, all costs of inspection at the source, including salaries and mileage costs, shall be paid by the permittee. Revised 11/13/09 Contract No.5507-1 Page 64 of 98 4-1.4 Test of Material. Before incorporation in the Work, the Contractor shall submit samples of materials, as the Engineer may require, at no cost to the Agency. The Contractor, at its expense, shall deliver the materials for testing to the place and at the time designated by the Engineer. Unless otherwise provided, all initial testing will be performed under the direction of the Engineer, and at no expense to the Contractor. If the Contractor is to provide and pay for testing, it will be stated in the Specifications. For private contracts, the testing expense shall be borne by the permittee. The Contractor shall notify the Engineer in writing, at least 15 days in advance, of its intention to use materials for which tests are specified, to allow sufficient time to perform the tests. The notice shall name the proposed supplier and source of material. If the notice of intent to use is sent before the materials are available for testing or inspection, or is sent so far in advance that the materials on hand at the time will not last but will be replaced by a new lot prior to use on the Work, it will be the Contractor's responsibility to renotify the Engineer when samples which are representative may be obtained. Except as specified in these Provisions, the Agency will bear the cost of testing of locally produced materials and/or on-site workmanship where the results of such tests meet or exceed the requirements indicated in the Standard Specifications, Technical Specification, and any Supplemental Provisions. The cost of all other tests shall be borne by the Contractor. At the option of the Engineer, the source of supply of each of the materials shall be approved by the Engineer before the delivery is started. All materials proposed for use may be inspected or tested at any time during their preparation and use. If, after incorporating such materials into the Work, it is found that sources of supply that have been approved do not furnish a uniform product, or if the product from any source proves unacceptable at any time, the Contractor shall furnish approved material from other approved sources. If any product proves unacceptable after improper storage, handling or for any other reason it shall be rejected, not incorporated into the work and shall be removed from the project site all at the Contractor's expense. Compaction tests may be made by the Engineer and all costs for tests that meet or exceed the requirements of the specifications shall be borne by the Agency. Said tests may be made at any place along the work as deemed necessary by the Engineer. The costs of any retests made necessary by noncompliance with the specifications shall be borne by the Contractor. 4-1.5 Certification. The Engineer may waive materials testing requirements of the Specifications and accept the manufacturer's written certification that the materials to be supplied meet those requirements. Material test data may be required as part of the certification. 4-1.6 Trade Names or Equals. The Contractor may supply any of the materials specified or offer an equivalent. The Engineer shall determine whether the material offered is equivalent to that specified. Adequate time shall be allowed for the Engineer to make this determination. Whenever any particular material, process, or equipment is indicated by patent, proprietary or brand name, or by name of manufacturer, such wording is used for the purpose of facilitating its description and shall be deemed to be followed by the words or equal. A listing of materials is not intended to be comprehensive, or in order of preference. The Contractor may offer any material, process, or equipment considered to be equivalent to that indicated. The substantiation of offers shall be submitted as provided in the contract documents. The Contractor shall, at its expense, furnish data concerning items offered by it as equivalent to those specified. The Contractor shall have the material tested as required by the Engineer to Revised 1 1/13/09 Contract No.5507-1 Page 65 of 98 determine that the quality, strength, physical, chemical, or other characteristics, including durability, finish, efficiency, dimensions, service, and suitability are such that the item will fulfill its intended function. Test methods shall be subject to the approval of the Engineer. Test results shall be reported promptly to the Engineer, who will evaluate the results and determine if the substitute item is equivalent. The Engineer's findings shall be final. Installation and use of a substitute item shall not be made until approved by the Engineer. If a substitute offered by the Contractor is not found to be equal to the specified material, the Contractor shall furnish and install the specified material. The specified Contract completion time shall not be affected by any circumstance developing from the provisions of this section. The Contractor is responsible for the satisfactory performance of substituted items. If, in the sole opinion of the Engineer, the substitution is determined to be unsatisfactory in performance, appearance, durability, compatibility with associated items, availability of repair parts and suitability of application the Contractor shall remove the substituted item and replace it with the originally specified item at no cost to the Agency. 4-1.7 Weighing and Metering Equipment. All scales and metering equipment used for proportioning materials shall be inspected for accuracy and certified within the past 12 months by the State of California Bureau of Weights and Measures, by the County Director or Sealer of Weights and Measures, or by a scale mechanic registered with or licensed by the County. The accuracy of the work of a scale service agency, except as stated herein, shall meet the standards of the California Business and Professions Code and the California Code of Regulations pertaining to weighing devices. A certificate of compliance shall be presented, prior to operation, to the Engineer for approval and shall be renewed whenever required by the Engineer at no cost to the Agency. All scales shall be arranged so they may be read easily from the operator's platform or area. They shall indicate the true net weight without the application of any factor. The figures of the scales shall be clearly legible. Scales shall be accurate to within 1 percent when tested with the plant shut down. Weighing equipment shall be so insulated against vibration or moving of other operating equipment in the plant area that the error in weighing with the entire plant running will not exceed 2 percent for any setting nor 1.5 percent for any batch. 4-1.8 Calibration of Testing Equipment. Testing equipment, such as, but not limited to pressure gages, metering devices, hydraulic systems, force (load) measuring instruments, and strain- measuring devices shall be calibrated by a testing agency acceptable to the Engineer at intervals not to exceed 12 months and following repairs, modification, or relocation of the equipment. Calibration certificates shall be provided when requested by the Engineer. 4-1.9 Construction Materials Dispute Resolution (Soils, Rock Materials, Concrete, Mortar and Related Materials, Masonry Materials, Bituminous Materials, Rock Products, and Modified Asphalts). In the interest of safety and public value, whenever credible evidence arises to contradict the test values of materials, the Agency and the Contractor will initiate an immediate and cooperative investigation. Test values of materials are results of the materials' tests, as defined by these Specifications or by the special provisions, required to accept the Work. Credible evidence is process observations or test values gathered using industry accepted practices. A contradiction Revised 11/13/09 Contract No.5507-1 Page 66 of 98 exists whenever test values or process observations of the same or similar materials are diverse enough such that the work acceptance or performance becomes suspect. The investigation shall allow access to all test results, procedures, and facilities relevant to the disputed work and consider all available information and, when necessary, gather new and additional information in an attempt to determine the validity, the cause, and if necessary, the remedy to the contradiction. If the cooperative investigation reaches any resolution mechanism acceptable to both the Agency and the Contractor, the contradiction shall be considered resolved and the cooperative investigation concluded. Whenever the cooperative investigation is unable to reach resolution, the investigation may then either conclude without resolution or continue by written notification of one party to the other requesting the implementation of a resolution process by committee. The continuance of the investigation shall be contingent upon recipient's agreement and acknowledged in writing within 3 calendar days after receiving a request. Without acknowledgement, the investigation shall conclude without resolution. The committee shall consist of three State of California Registered Civil Engineers. Within 7 calendar days after the written request notification, the Agency and the Contractor will each select one engineer. Within 14 calendar days of the written request notification, the two selected engineers will select a third engineer. The goal in selection of the third member is to complement the professional experience of the first two engineers. Should the two engineers fail to select the third engineer, the Agency and the Contractor shall each propose 2 engineers to be the third member within 21 calendar days after the written request notification. The first two engineers previously selected shall then select one of the four proposed engineers in a blind draw. The committee shall be a continuance of the cooperative investigation and will re-consider all available information and if necessary gather new and additional information to determine the validity, the cause, and if necessary, the remedy to the contradiction. The committee will focus upon the performance adequacy of the material(s) using standard engineering principles and practices and to ensure public value, the committee may provide engineering recommendations as necessary. Unless otherwise agreed, the committee will have 30 calendar days from its formation to complete their review and submit their findings. The final resolution of the committee shall be by majority opinion, in writing, stamped and signed. Should the final resolution not be unanimous, the dissenter may attach a written, stamped, and signed minority opinion. Once started, the resolution process by committee shall continue to full conclusion unless: 1. Within 7 days of the formation of the committee, the Agency and the Contractor reach an acceptable resolution mechanism; or 2. Within 14 days of the formation of the committee, the initiating party withdraws its written notification and agrees to bear all investigative related costs thus far incurred; or 3. At any point by the mutual agreement of the Agency and the Contractor. Unless otherwise agreed, the Contractor shall bear and maintain a record for all the investigative costs until resolution. Should the investigation discover assignable causes for the contradiction, the assignable party, the Agency or the Contractor, shall bear all costs associated with the investigation. Should assignable causes for the contradiction extended to both parties, the investigation will assign costs cooperatively with each party or when necessary, equally. Should the investigation substantiate a contradiction without assignable cause, the investiga- tion will assign costs cooperatively with each party or when necessary, equally. Should the investigation be unable to substantiate a contradiction, the initiator of the investigation shall bear all investigative costs. All claim notification requirements of the contract pertaining to the contradiction shall be suspended until the investigation is concluded. Revised 11/13/09 Contract No.5507-1 Page 67 of 98 4-2 MATERIALS TRANSPORTATION, HANDLING AND STORAGE. The Contractor shall order, purchase, transport, coordinate delivery, accept delivery, confirm the quantity and quality received, prepare storage area(s), store, handle, protect, move, relocate, remove and dispose excess of all materials used to accomplish the Work. Materials shall be delivered to the site of the work only during working hours, as defined in Section 6-7.2, and shall be accompanied by bills of lading that shall clearly state for each delivery: the name of the Contractor as consignee, the project name and number, address of delivery and name of consignor and a description of the material(s) shipped. Prior to storage of any materials which have been shipped to or by the Contractor to any location within the Agency's boundaries the Contractor shall provide the Engineer a copy of lease agreements for each property where such materials are stored. The lease agreement shall clearly state the term of the lease, the description of materials allowed to be stored and shall provide for the removal of the materials and restoration of the storage site within the time allowed for the Work. All such storage shall conform to all laws and ordinances that may pertain to the materials stored and to preparation of the storage site and the location of the site on which the materials are stored. Loss, damage or deterioration of all stored materials shall be the Contractor's responsibility. Conformance to the requirements of this section, both within and outside the limits of work are a part of the Work. The Engineer shall have the right to verify the suitability of materials and their proper storage at any time during the Work. SECTION 5 -UTILITIES 5-1 LOCATION. The Agency and affected utility companies have, by a search of known records, endeavored to locate and indicate on the Plans, all utilities which exist within the limits of the work. However, the accuracy and/or completeness of the nature, size and/or location of utilities indicated on the Plans is not guaranteed. Where underground main distribution conduits such as water, gas, sewer, electric power, telephone, or cable television are shown on the Plans, the Contractor shall assume that every property parcel will be served by a service connection for each type of utility. As provided in Section 4216 of the California Government Code, at least 2 working days prior to commencing any excavation, the Contractor shall contact the regional notification center (Underground Service Alert of Southern California) and obtain an inquiry identification number. The California Department of Transportation is not required by Section 4216 to become a member of the regional notification center. The Contractor shall contact it for location of its subsurface installations. The Contractor shall determine the location and depth of all utilities, including service connections, which have been marked by the respective owners and which may affect or be affected by its operations. If no pay item is provided in the Contract for this work, full compensation for such work shall be considered as included in the prices bid for other items of work. 5-2 PROTECTION. The Contractor shall not interrupt the service function or disturb the support of any utility without authority from the owner or order from the Agency. All valves, switches, vaults, and meters shall be maintained readily accessible for emergency shutoff. Where protection is required to ensure support of utilities located as shown on the Plans or in accordance with Section 5-1, the Contractor shall, unless otherwise provided, furnish and place the necessary protection at its expense. Revised 1 1/13/09 Contract No.5507-1 Page 68 of 98 Upon learning of the existence and location of any utility omitted from or shown incorrectly on the Plans, the Contractor shall immediately notify the Engineer in writing. When authorized by the Engineer, support or protection of the utility will be paid for as provided in Section 3-2.2.3 or 3-3. The Contractor shall immediately notify the Engineer and the utility owner if any utility is disturbed or damaged. The Contractor shall bear the costs of repair or replacement of any utility damaged if located as noted in Section 5-1. When placing concrete around or contiguous to any non-metallic utility installation, the Contractor shall at its expense: 1. Furnish and install a 2 inch cushion of expansion joint material or other similar resilient material; or 2. Provide a sleeve or other opening which will result in a 2 inch minimum-clear annular space between the concrete and the utility; or 3. Provide other acceptable means to prevent embedment in or bonding to the concrete. Where concrete is used for backfill or for structures which would result in embedment, or partial embedment, of a metallic utility installation; or where the coating, bedding or other cathodic protection system is exposed or damaged by the Contractor's operations, the Contractor shall notify the Engineer and arrange to secure the advice of the affected utility owner regarding the procedures required to maintain or restore the integrity of the system. 5-3 REMOVAL. Unless otherwise specified, the Contractor shall remove all interfering portions of utilities shown on the Plans or indicated in the Bid documents as "abandoned" or "to be abandoned in place". Before starting removal operations, the Contractor shall ascertain from the Agency whether the abandonment is complete, and the costs involved in the removal and disposal shall be included in the Bid for the items of work necessitating such removals. 5-4 RELOCATION. When feasible, the owners responsible for utilities within the area affected by the Work will complete their necessary installations, relocations, repairs, or replacements before commencement of work by the Contractor. When the Plans or Specifications indicate that a utility installation is to be relocated, altered, or constructed by others, the Agency will conduct all negotiations with the owners and work will be done at no cost to the Contractor. Utilities which are relocated in order to avoid interference shall be protected in their position and the cost of such protection shall be included in the Bid for the items of work necessitating such relocation. After award of the Contract, portions of utilities which are found to interfere with the Work will be relocated, altered or reconstructed by the owners, or the Engineer may order changes in the Work to avoid interference. Such changes will be paid for in accordance with Section 3-2. When the Plans or Specifications provide for the Contractor to alter, relocate, or reconstruct a utility, all costs for such work shall be included in the Bid for the items of work necessitating such work. Temporary or permanent relocation or alteration of utilities requested by the Contractor for its convenience shall be its responsibility and it shall make all arrangements and bear all costs. The utility owner will relocate service connections as necessary within the limits of the Work or within temporary construction or slope easements. When directed by the Engineer, the Contractor shall arrange for the relocation of service connections as necessary between the meter and property line, or between a meter and the limits of temporary construction or slope easements. The relocation of Revised 11/13/09 Contract No. 5507-1 Page 69 of 98 such service connections will be paid for in accordance with provisions of Section 3-3. Payment will include the restoration of all existing improvements which may be affected thereby. The Contractor may agree with the owner of any utility to disconnect and reconnect interfering service connections. The Agency will not be involved in any such agreement. In conformance with Section 5-6 the Contractor shall coordinate the work with utility agencies and companies. Prior to the installation of any and all utility structures within the limits of work by any utility agency or company, or its contractor, the Contractor shall place all curb or curb and gutter that is a part of the work and adjacent to the location where such utility structures are shown on the plans and are noted as being located, relocated or are otherwise shown as installed by others. In order to minimize delays to the Contractor caused by the failure of other parties to relocate utilities that interfere with the construction, the Contractor, upon the Engineer's approval, may be permitted to temporarily omit the portion of work affected by the utility. If such temporary omission is approved by the Engineer the Contractor shall place survey or other physical control markers sufficient to locate the curb or curb and gutter to the satisfaction of the utility agency or company. Such temporary omission shall be for the Contractor's convenience and no additional compensation will be allowed therefore or for additional work, materials or delay associated with the temporary omission. The portion thus omitted shall be constructed by the Contractor immediately following the relocation of the utility involved unless otherwise directed by the Engineer. 5-5 DELAYS. The Contractor shall notify the Engineer of its construction schedule insofar as it affects the protection, removal, or relocation of utilities. Said notification shall be included as a part of the construction schedule required in Section 6-1. The Contractor shall notify the Engineer in writing of any subsequent changes in the construction schedule which will affect the time available for protection, removal, or relocation of utilities. The Contractor will not be entitled to damages or additional payment for delays attributable to utility relocations or alterations if correctly located, noted, and completed in accordance with Section 5-1. The Contractor may be given an extension of time for unforeseen delays attributable to unreasonably protracted interference by utilities in performing work correctly shown on the Plans. The Agency will assume responsibility for the timely removal, relocation, or protection of existing main or trunkline utility facilities within the area affected by the Work if such utilities are not identified in the Contract Documents. The Contractor will not be assessed liquidated damages for any delay caused by failure of Agency to provide for the timely removal, relocation, or protection of such existing facilities. If the Contractor sustains loss due to delays attributable to interferences, relocations, or alterations not covered by Section 5-1, which could not have been avoided by the judicious handling of forces, equipment, or plant, there shall be paid to the Contractor such amount as the Engineer may find to be fair and reasonable compensation for such part of the Contractor's actual loss as was unavoidable and the Contractor may be granted an extension of time. 5-6 COOPERATION. When necessary, the Contractor shall so conduct its operations as to permit access to the Work site and provide time for utility work to be accomplished during the progress of the Work. Revised 11/13/09 Contract No.5507-1 Page 70 of 98 SECTION 6 - PROSECUTION, PROGRESS, AND ACCEPTANCE OF THE WORK 6-1 CONSTRUCTION SCHEDULE AND COMMENCEMENT OF WORK. Except as otherwise provided herein and unless otherwise prohibited by permits from other agencies as may be required by law the Contractor shall begin work within 7 calendar days after receipt of the "Notice to Proceed". A construction schedule shall be provided at Pre-Construction Meeting in accordance with Section 6, Paragraph 6-1.1 of SSPWC, 2009 Edition. 6-1.1 Pre-Construction Meeting. After, or upon, notification of contract award, the Engineer will set the time and location for the Preconstruction Meeting. Attendance of the Contractor's management personnel responsible for the management, administration, and execution of the project is mandatory for the meeting to be convened. Failure of the Contractor to have the Contractor's responsible project personnel attend the Preconstruction Meeting will be grounds for default by Contractor per Section 6-4. No separate payment will be made for the Contractor's attendance at the meeting. The notice to proceed will only be issued on or after the completion of the Preconstruction meeting. 6-1.8 Measurement and Payment of Construction Schedule. The Contractor's preparation, revision and maintenance of the Construction Schedule are incidental to the work and no separate payment will be made therefore. 6-2 PROSECUTION OF WORK. To minimize public inconvenience and possible hazard and to restore street and other work areas to their original condition and state of usefulness as soon as practicable, the Contractor shall diligently prosecute the Work to completion. If the Engineer determines that the Contractor is failing to prosecute the Work to the proper extent, the Contractor shall, upon orders from the Engineer, immediately take steps to remedy the situation. All costs of prosecuting the Work as described herein shall be included in the Contractor's Bid. Should the Contractor fail to take the necessary steps to fully accomplish said purposes, after orders of the Engineer, the Engineer may suspend the work in whole or part, until the Contractor takes said steps. As soon as possible under the provisions of the Specifications, the Contractor shall backfill all excavations and restore to usefulness all improvements existing prior to the start of the Work. If Work is suspended through no fault of the Agency, all expenses and losses incurred by the Contractor during such suspensions shall be borne by the Contractor. If the Contractor fails to properly provide for public safety, traffic, and protection of the Work during periods of suspension, the Agency may elect to do so, and deduct the cost thereof from monies due the Contractor. Such actions will not relieve the Contractor from liability. 6-2.1 Order of Work. The work to be done shall consist of furnishing all labor, equipment and materials, and performing all operations necessary to complete the Project Work as shown on the Project Plans and as specified in the Specifications. 6-2.3 Project Meetings. The Engineer will establish the time and location of weekly Project Meetings. The Contractor's Representative shall attend each Project Meeting. The Project Representative shall be the individual determined under Section 7-6, "The Contractor's Representative". No separate payment for attendance of the Contractor, the Contractor's Representative or any other employee or subcontractor or subcontractor's employee at these meetings will be made. Revised 1 1/13/09 Contract No.5507-1 Page 71 of 98 6-3 SUSPENSION OF WORK. 6-3.1 General. The Work may be suspended in whole or in part when determined by the Engineer that the suspension is necessary in the interest of the Agency. The Contractor shall comply immediately with any written order of the Engineer. Such suspension shall be without liability to the Contractor on the part of the Agency except as otherwise specified in Section 6-6.3. 6-3.2 Archaeological and Paleontological Discoveries. If discovery is made of items of archaeological or paleontological interest, the Contractor shall immediately cease excavation in the area of discovery and shall not continue until ordered by the Engineer. When resumed, excavation operations within the area of discovery shall be as directed by the Engineer. Discoveries which may be encountered may include, but not be limited to, dwelling sites, stone implements or other artifacts, animal bones, human bones, and fossils. The Contractor shall be entitled to an extension of time and compensation in accordance with the provisions of Section 6-6. 6-4 DEFAULT BY CONTRACTOR. If the Contractor fails to begin delivery of material and equipment, to commence the Work within the time specified, to maintain the rate of delivery of material, to execute the Work in the manner and at such locations as specified, or fails to maintain the Work schedule which will insure the Agency's interest, or, if the Contractor is not carrying out the intent of the Contract, the Agency may serve written notice upon the Contractor and the Surety on its Faithful Performance Bond demanding satisfactory compliance with the Contract. The Contract may be canceled by the Board without liability for damage, when in the Board's opinion the Contractor is not complying in good faith, has become insolvent, or has assigned or subcontracted any part of the Work without the Board's consent. In the event of such cancellation, the Contractor will be paid the actual amount due based on Contract Unit Prices or lump sums bid and the quantity of the Work completed at the time of cancellation, less damages caused to the Agency by acts of the Contractor. The Contractor, in having tendered a Bid, shall be deemed to have waived any and all claims for damages because of cancellation of Contract for any such reason. If the Agency declares the Contract canceled for any of the above reasons, written notice to that effect shall be served upon the Surety. The Surety shall, within five (5) days, assume control and perform the Work as successor to the Contractor. If the Surety assumes any part of the Work, it shall take the Contractor's place in all respects for that part, and shall be paid by the Agency for all work performed by it in accordance with the Contract. If the Surety assumes the entire Contract, all money due the Contractor at the time of its default shall be payable to the Surety as the Work progresses, subject to the terms of the Contract. If the Surety does not assume control and perform the Work within 5 days after receiving notice of cancellation, or fails to continue to comply, the Agency may exclude the Surety from the premises. The Agency may then take possession of all material and equipment and complete the Work by Agency forces, by letting the unfinished Work to another Contractor, or by a combination of such methods. In any event, the cost of completing the Work shall be charged against the Contractor and its Surety and may be deducted from any money due or becoming due from the Agency. If the sums due under the Contract are insufficient for completion, the Contractor or Surety shall pay to the Agency within 5 days after the completion, all costs in excess of the sums due. Revised 11/13/09 Contract No.5507-1 Page 72 of 98 The provisions of this section shall be in addition to all other rights and remedies available to the Agency under law. 6-5 TERMINATION OF CONTRACT. The Board may terminate the Contract at its own discretion or when conditions encountered during the Work make it impossible or impracticable to proceed, or when the Agency is prevented from proceeding with the Contract by act of God, by law, or by official action of a public authority. 6-6 DELAYS AND EXTENSIONS OF TIME. 6-6.1 General. If delays are caused by unforeseen events beyond the control of the Contractor, such delays will entitle the Contractor to an extension of time as provided herein, but the Contractor will not be entitled to damages or additional payment due to such delays, except as provided in 6- 6.3.

Please refer to the XRF Lead Data Table in Appendix D for building components and surface coatings considered LCSCs at the subject building. Technical Lead-Related Construction Specification Calavera Hill Treatment Plant March 30, 2011 Page 4 WINZLER<$k.KELJLY At present there is no state or federal regulation requiring mandatory lead removal or abatement prior to disturbance or demolition of structures with identified lead materials. However, there are applicable Cal/OSHA worker protection and training requirements; California Environmental Protection Agency (Cal/EPA) waste disposal requirements, California Department of Public Health (CDPH) requirements for public and residential buildings, and Senate Bill (SB) 460 lead hazard regulations that apply to lead-related construction activities, abatement activities and their associated wastes. The following is a brief discussion and summary of applicable regulatory requirements: • Cal/OSHA: Title 8, California Code of Regulation (CCR), Section 1532.1 (8 CCR 1532.1) governs occupational exposure to lead. This regulation requires that prior to initiation of certain activities, referred to as "trigger tasks", workers must be trained, medically evaluated, and properly fitted with respiratory protection, and protective clothing until statistically reliable personal eight-hour time weighted average (TWA) results indicate lead exposure levels below the Personal Exposure Limit (PEL) for each unique task which disturbs lead-based and lead-containing coatings. This process is known as a Negative Exposure Assessment or NEA. If the result of the exposure assessment is above the Action Level (AL) additional monitoring is required and if the result is above the PEL additional exposure monitoring, worker protection (including respirator protection and PPE), training and medical requirements apply. However even where the NEA criteria is met, certain hazard communication training and work practice controls still apply where lead is disturbed. "Trigger tasks" are tasks that are assumed to exceed the PEL pending an exposure assessment and they encompass the majority of construction activities that disturb surface coatings. Examples of "trigger" tasks range from manual paint scraping as a lower expected exposure up to hot work and abrasive blasting as the highest expected exposures, and include any non-listed task that the employer determines may potentially expose employees to lead levels above the AL. NOTE - "OSHA does not consider any method that relies solely on the analysis of bulk materials or surface content of lead (or other toxic material) to be acceptable for safely predicting employee exposure to airborne contaminates. Without air monitoring results or without the benefit of historical or objective data (including air sampling which clearly demonstrates that the employee can not be exposed above the action level during any process, operation, or activity) the analysis of bulk or surface samples can not be used to determine employee exposure." OSHA Standard Interpretation 5/8/2000. Furthermore, OSHA states that these rules apply to "any detectable concentration of lead" without a specified detection level. Due to the Consumer Product Safety Commission currently allowing paint to contain up to 600 parts per million (ppm) of lead, the variation of lead content due to aging and weathering, and the variation of detection limits associated with both paint chip and x-ray fluorescence (XRF) analysis, it is recommended that all painted or coated surfaces be treated as potentially containing lead. Clearly, positive analytical results by either method can be used to indicate that detectable lead is present but negative results cannot be interpreted as conclusively demonstrating the absence of lead. Analytical data of bulk paint/coating materials or surface content (by XRF) of lead can be helpful in evaluation of lead-related environmental risks in general but cannot be used to Technical Lead-Related Construction Specification March 30, 2011 Calavera Hill Treatment Plant Page 5 calculate worker exposures and are not a substitute for employee exposure monitoring. As a result of the above, any employee that works around potential lead-based or lead-containing coatings must have HAZCOM training and personal exposure air monitoring is additionally required for employees that disturb such coatings. Significant additional certification, notification, and work practices are required for materials found to be "lead-based". • Any welding, cutting or heating of metal surfaces containing surface coatings should be conducted in accordance with 29 CFR 1926.354 and 8 CCR 1537. These regulations require surfaces covered with toxic preservatives, and in enclosed areas, be stripped of all toxic coatings for a distance of at least 4 inches, in all directions, from the area of heat application prior to the initiation of such heat application. • Cal/EPA through the Division of Toxic Substance Control (DTSC) regulates disposal of lead hazardous waste (Title 22 Division 4.5, Environmental Health Standards for the Management of Hazardous Waste). DTSC has issued guidance indicating that architectural debris with intact lead paint is normally expected to be handled as general construction waste. However, waste stream segregation and analysis is still required for all paint or coating debris regardless of if the paint or coating is intact on a building component or not. The resulting wastes may be hazardous under California and federal RCRA standards for lead and therefore require proper handling, packaging, labeling, and transportation under a proper manifest to a permitted hazardous waste storage, treatment and disposal facility. • CDPH: The California Department of Public Health (CDPH) has specific requirements (Title 17 Sections 35001 thru 36100 et. al.) for hazard assessment and work in public or residential structures. These regulations require special certifications, work practices, and notification for such activities. « Senate Bill 460 (SB 460): An act to amend Section 1941.1 of the Civil Code, and to amend Sections 17961, 17980, and 124130 of, and to add Sections 17920.10, 105251, 105252, 105253, 105254, 105255, 105256, and 105257 to, the Health and Safety Code, relating to lead abatement. This bill allows for fines and criminal penalties to be levied on any person who is found to have performed lead abatement without containment or created a measurable lead hazard based upon current CDPH standards. The testing for this determination can be initiated by any local or state building inspector, health department inspector, or other designated state or local official. A determination of a lead hazard is not solely based upon the lead content of the paint or coating and can be the result of the disturbance of such materials with low concentrations of lead. Written notification to Cal/OSHA must be accomplished should LBP activities involve more than 100 square or linear feet of removal in accordance with the requirements of 8 CCR 1532.1. Proper written notification to CDPH may be required, depending upon the nature of the activity. Proper waste characterization and disposal of lead-containing materials and lead-contaminated debris should be conducted in accordance with Title 22 of the California Code of Regulations and the California Health and Safety Code, Section 25157.8.

The survey was conducted to identify and sample suspect asbestos-containing materials (ACMs) and asbestos-containing construction materials (ACCMs); to sample representative building components for the presence of lead-containing surface coatings, lead-based paints, and lead-bearing substances (LCSCs, LBPs, and LBSs) and to identify potential polychlorinated biphenyl (PCB)-containing light fixture ballasts, fluorescent light tubes (FLTs), mercury-containing thermostat switches and other universal waste rule (UWR) materials. Physical limitations, such as locked rooms, were not encountered during the survey and testing activities. There is a possibility that additional hazardous materials may be encountered in inaccessible areas (e.g., interstitial ceiling and wall spaces) during building demolition activities. Suspect hazardous materials encountered during demolition activities that have not been assessed either may be assumed to be hazardous and handled accordingly, or may be sampled by the appropriate personnel and analyzed to assess whether they are hazardous. The results of the survey and testing indicate that hazardous building materials are present at the subject structures. The following tables list the hazardous materials identified within the subject site structures, including the location and the estimated total quantity of the identified hazardous materials: Table 1 of 9 ADMINISTRATION BUILDING CALAVERA HILL MATERIAL/COMPONENT DESCRIPTION Asbestos-containing Roof penetration mastic Asbestos-containing Wall and window frame sealant Asbestos-containing Sink under coating mastic Asbestos-con tai n i ng 12"xl2" Brown floor tile and associated black mastic Asbestos-containing Transite pipe debris Lead-Based Paints ( Color/Substrate/Component): Gray/Meta I/Beam White/Porceiain/Floor drain LOCATION Roof seams and penetrations Exterior walls and windows Kitchen Lobby, kitchen and electrical room Work area Work area Closet CONDITION Good/Non-friable Good/Non-friable Good/Non-friable Good/Non-friable Damagcd/Non- friable Intact Intact ESTIMATED TOTAL QUANTITY (SF/LF/EA) 100SF 150LF 1 EA I,500SF 4SF 150LF 1 EA .

Please refer to the XRF Lead Data Table in Appendix D for building components and surface coatings considered LCSCs at the subject building. Asbestos Survey The results of the asbestos survey indicate that ACMs are present at some of the subject site structures, which may be impacted by the impending demolition activities. At no time should the identified ACMs or ACCMs be drilled, cut, sanded, scraped or otherwise disturbed by untrained personnel. These materials should be removed prior to any activities which will impact these materials. Asbestos disturbance and/or removal operations must be conducted by a California Occupational Safety and Health Administration (Cal/OSHA)-registered and State licensed asbestos removal contractor. Disturbance and/or abatement operations should be performed under the direct observation of a California Certified Asbestos Consultant. Construction activities involving the potential for impacting ACMs/ACCMs should be conducted in accordance with the requirements of Title 8 of the California Code of Regulations, Section 1529 (8 CCR 1529). Survey Report - Executive Summary March 30, 2011 Calavera Treatment Plant Page 6 WINZLER&.KELLY For all abatement activities which will involve the removal of at least 100 square feet of identified asbestos-containing materials, notification must be made to the San Diego Air Pollution Control District (SDAPCD). Notification to SDAPCD must be accomplished ten working days prior to the initiation of such activities. For abatement activities which will involve asbestos-related work of at least 100 square or linear feet, written notification must be made to Cal/OSHA. Notification to Cal/OSHA must be accomplished 24 hours prior to the initiation of such activities. Notification to employees and contractors working within the building should be made in accordance with the California Health and Safety Code, Section 25915 et.seq. and Proposition 65. Lead Testing Services The lead testing services revealed that building components with coatings defining them as LBPs. LBSs and LCSCs are present at some of the subject site structures, which may be impacted by the impending demolition activities. All demolition involving potential and identified lead-containing surfaces should be conducted in accordance with Title 8, California Code of Regulations, Section 1532.1 and 29 CFR 1926.62. In addition, all activities involving identified lead-based paints must be conducted in accordance with Title 17, California Code of Regulations, Division 1, Chapter 8, Sections 35001 through 36100, which proscribes the use of CDPH -certified workers, work practices, and other requirements. At present there is no state or federal regulation requiring mandatory lead removal or abatement prior to disturbance or demolition of structures with identified lead materials. However, there are applicable Cal/OSHA worker protection and training requirements; Cal/EPA waste disposal requirements, CDPH requirements for public and residential buildings, and SB 460 lead hazard regulations that apply to lead- related construction activities, abatement activities and their associated wastes. The following is a brief discussion and summary of applicable regulatory requirements: * Cal/OSHA: Title 8, California Code of Regulation (CCR), Section 1532.1 (8 CCR 1532.1) governs occupational exposure to lead. This regulation requires that prior to initiation of certain activities, referred to as "trigger tasks", workers must be trained, medically evaluated, and properly fitted with respiratory protection, and protective clothing until statistically reliable personal eight-hour time weighted average (TWA) results indicate lead exposure levels below the Personal Exposure Limit (PEL) for each unique task which disturbs lead-based and lead- containing coatings. This process is known as a Negative Exposure Assessment or NEA. If the result of the exposure assessment is above the Action Level (AL) additional monitoring is required and if the result is above the PEL additional exposure monitoring, worker protection (including respirator protection and PPE), training and medical requirements apply. However even where the NEA criteria is met, certain hazard communication training and work practice controls still apply where lead is disturbed. "Trigger tasks" are tasks that are assumed to exceed the PEL pending an exposure assessment and they encompass the majority of construction activities that disturb surface coatings. Examples of "trigger" tasks range from manual paint scraping as a lower expected exposure up to hot work and abrasive blasting as the highest expected exposures, and include any non-listed task that the employer determines may potentially expose employees to lead levels above the AL. Survey Report - Executive Summary March 30, 2011 Calavera Treatment Plant Page 7 WINZLER&KELLY NOTE - "OSHA does not consider any method that relies solely on the analysis of bulk materials or surface content of lead (or other toxic material) to be acceptable for safely predicting employee exposure to airborne contaminates. Without air monitoring results or without the benefit of historical or objective data (including air sampling which clearly demonstrates that the employee cannot be exposed above the action level during any process, operation, or activity) the analysis of bulk or surface samples cannot be used to determine employee exposure." OSHA Standard Interpretation 5/8/2000. Furthermore, OSHA states that these rules apply to "any detectable concentration of lead" without a specified detection level. Due to the Consumer Product Safety Commission currently allowing paint to contain up to 600 parts per million (ppm) of lead, the variation of lead content due to aging and weathering, and the variation of detection limits associated with both paint chip and XRF analysis, it is recommended that all painted or coated surfaces be treated as potentially containing lead. Clearly, positive analytical results by either method can be used to indicate that detectable lead is present but negative results cannot be interpreted as conclusively demonstrating the absence of lead. Analytical data of bulk paint/coating materials or surface content (by XRF) of lead can be helpful in evaluation of lead-related environmental risks in general but cannot be used to calculate worker exposures and are not a substitute for employee exposure monitoring. As a result of the above, any employee that works around potential lead-based or lead-containing coatings must have HAZCOM training and personal exposure air monitoring is additionally required for employees that disturb such coatings. Significant additional certification, notification, and work practices are required for materials found to be "lead-based". + Any welding, cutting or heating of metal surfaces containing surface coatings should be conducted in accordance with 29 CFR 1926.354 and 8 CCR 1537. These regulations require surfaces covered with toxic preservatives, and in enclosed areas, be stripped of all toxic coatings for a distance of at least 4 inches, in all directions, from the area of heat application prior to the initiation of such heat application. * Cal/EPA through the Division of Toxic Substance Control (DTSC) regulates disposal of lead hazardous waste (Title 22 Division 4.5, Environmental Health Standards for the Management of Hazardous Waste). DTSC has issued guidance indicating that architectural debris with intact lead paint is normally expected to be handled as general construction waste. However, waste stream segregation and analysis is still required for all paint or coating debris regardless of if the paint or coating is intact on a building component or not. The resulting wastes may be hazardous under California and federal RCRA standards for lead and therefore require proper handling, packaging, labeling, and transportation under a proper manifest to a permitted hazardous waste storage, treatment and disposal facility. * CDPH: The State of California Department of Public Health (CDPH) has specific requirements (Title 17 Sections 35001 thru 36100 et. al.) for hazard assessment and work in public or residential structures. These regulations require special certifications, work practices, and notification for such activities. * Senate Bill 460 (SB 460): An act to amend Section 1941.1 of the Civil Code, and to amend Sections 17961, 17980, and 124130 of, and to add Sections 17920.10, 105251, 105252, 105253, 105254, 105255, 105256, and 105257 to, the Health and Safety Code, relating to lead abatement. This bill allows for fines and criminal penalties to be levied on any person who is found to have Survey Report - Executive Summary March 30,2011 Calavera Treatment Plant Page 8 WINZUER<SzL.KELLY performed lead abatement without containment or created a measurable lead hazard based upon current CDPH standards. The testing for this determination can be initiated by any local or state building inspector, health department inspector, or other designated state or local official. A determination of a lead hazard is not solely based upon the lead content of the paint or coating and can be the result of the disturbance of such materials with low concentrations of lead. Written notification to Cal/OSHA must be accomplished should LBP activities involve more than 100 square or linear feet of removal in accordance with the requirements of 8 CCR 1532.1. Proper written notification to CDPH may be required, depending upon the nature of the activity. Proper waste characterization and disposal of lead-containing materials and lead-contaminated debris should be conducted in accordance with Title 22 of the California Code of Regulations and the California Health and Safety Code, Section 25157.8. Universal Waste The hazardous material building survey revealed that universal waste materials are present at some of the subject site structures, which may be impacted by the impending demolition activities. Winzler & Kelly's limited spot checks indicated that PCB-containing light fixture ballasts are present in areas of the investigated facility; however, due to the limited nature of the random spot checks, Winzler & Kelly recommends that all light fixtures be visually inspected, prior to disposal, to determine if they contain PCBs. Those ballasts marked "No PCBs" or "PCB Free", should be considered as such. All potential and identified PCB-containing light fixture ballasts should be handled, collected, transported and disposed in accordance with the requirements of Title 22 of the California Code of Regulations, Section 67426.1(22 CCR 67426.1). Fluorescent light tubes, mercury-containing thermostat switch capsules, and other Universal Waste Rule components should be handled in accordance with the requirements of Title 22 of the California Code of Regulations, Section 66273 et seq. (22 CCR 66273). It is the contractor's responsibly to confirm the hazardous material quantities present prior to initiating renovation or demolition activities at the subject buildings. Should materials similar to those identified in this report, or other forms of suspect hazardous materials be present or identified, maintenance personnel/contractors should be instructed to immediately cease work activities which may initiate a fiber release episode, and notify the appropriate management personnel.

The survey was conducted to identify and sample suspect asbestos-containing materials (ACMs) and asbestos- containing construction materials (ACCMs); to sample representative building components for the presence of lead-containing surface coatings, lead-based paints, and lead-bearing substances (LCSCs, LBPs, and LBSs), and to identify potential polychlorinated biphenyl (PCB)-containing light fixture ballasts, fluorescent light tubes (FLTS), mercury-containing thermostat switches, and other universal waste rule (UWR) materials and building related hazardous materials. The survey was performed on March 16 and 17, 2011 by Mr. Steve Pitts, Mr. Stephen Reese, Mr. Chris LeMaster and Mr. Brian Ford. Mr. Jerry Sherman performed report preparation and Mr. Reese performed report review. Mr. Pitts, Mr. Reese and Mr. Sherman are California Occupational Safety and Health Administration (Cal/OSHA)-Certified Asbestos Consultants and California Department of Public Health (CDPH)-CertJfied Lead-Related Inspectors/Risk Assessors. Mr. Reese is also a CDPH-Certified Lead Project Monitor. Mr. LeMaster and Mr. Ford are California Occupational Safety and Health Administration (Cal/OSHA)-Certified Site Surveillance Technicians. All members of the survey team are employees of Winzler & Kelly and have received Hazardous Waste Operations and Emergency Response (HAZWOPER) training in accordance with 8 California Code of Regulations (CCR) 5194. Building and Structure Descriptions The survey and testing was conducted at ten structures within the abandoned Calavera Hill Treatment Plant. The structures consisted of three buildings (Administration, Chlorine and Sludge Handling) constructed with concrete and wood framing; interior walls and ceilings were finished with plaster, drywall/joint compound and acoustic ceiling panels; floors were unfinished or finished with vinyl floor tile; and the roofs consisted of built- up roofing materials. Physical limitations, such as locked rooms, were not encountered during the survey and testing. There is a possibility that additional hazardous materials may be encountered in inaccessible areas (e.g., locked rooms, interstitial ceiling and wall spaces) during building demolition/renovation activities. Suspect hazardous materials encountered during demolition activities that have not been assessed either may be assumed to be hazardous and handled accordingly, or may be sampled and analyzed to assess whether they are hazardous. METHODOLOGY Asbestos - Survey Methodology Suspect ACM, ACCM and PACM visual identification was performed by entering representative areas and assessing all accessible structural, architectural, and mechanical components for the presence of suspect asbestos-containing materials. Previous information was not available at the time of the survey. All findings, conclusions, and analytical data presented in this report are based on the field inspection and sampling data obtained by Winzler & Kelly's inspection during this project. Survey Report - Section 2 March 30, 2011 Calavera Treatment Plant Page 1 Each suspect ACM/ACCM identified was bulk sampled in accordance with sampling guidelines established by the Environmental Protection Agency, and satisfies 29 CFR 1926.1101, 40 CFR 763, 8 CCR 1529, and SDAPCD rules. The following summarizes the sampling procedures utilized: 1. The location and total quantity of each ACM/ACCM was tabulated. 2. These materials were then categorized into homogeneous materials. A homogeneous material is defined as being uniform in texture, color, and date of application. 3. A sampling scheme was developed based upon the location and quantity of the various homogeneous materials. 4. Bulk samples were collected by trained personnel using an appropriate sampling tool and a leak-tight container. 5. Decontamination of bulk sampling tools to prevent the spread of secondary contamination to subsequent bulk samples. 6. Each bulk sample was individually numbered and recorded on a Bulk Sample Log. 1. A Chain of Custody Record was maintained for the samples. A representative drawing showing asbestos sample locations can be found in Appendix B of this document. Asbestos - Analytical Methodology All bulk samples were analyzed by AmeriSci of Los Angeles, California. AmeriSci is accredited by the National Voluntary Laboratory Accreditation Program (NVLAP), the National Institute of Standards and Technology (NIST) and is a successful participant in the Proficiency Analytical Testing Program (PAT). Polarized Light Microscopy (PLM) All bulk samples were analyzed by Polarized Light Microscopy (PLM) utilizing dispersion staining techniques in accordance with the EPA Method: "Method for the Determination of Asbestos in Bulk Building Materials U.S. EPA/600/R-93/116" dated July 1993, and adopted by the National Voluntary Laboratory Accreditation Program (NVLAP), NVLAP Test Method Code 18/AO1, as affiliated with the National Institute for Standards and Technology (NIST). Each sample was subjected to two microscopy examinations. The first examination was performed at 20X magnification using a stereo microscope equipped with an external illuminator. Each sample was examined for layering, homogeneity, and the presence of fibrous and non-fibrous materials. An estimate of the percentage for each sample component, relative to the entire sample volume, was made. When discrete strata are identified as a separate material, fibers are first identified and quantified by layer and then the results are combined to yield an estimate of total percent asbestos present. The second examination was performed at a range from of IOOX to 400X magnification using a Polarized Light Microscope equipped with two polarizing filters to observe specific optical characteristics. The use of polarized light allows the determination of refractive indices along specific crystallographic axes. Morphology Survey Report - Section 2 March 30,2011 Calavera Treatment Plant Page 2 WINZLER<SL.KELJLY and color were also observed. A retardation plate was placed at a 45 degree angle between the cross polars to determine the sign of elongation using orthoscopic illumination. Orientation of the two filters such that their vibration planes were perpendicular allowed observation of the birefringence and extinction characteristics of anisotropic particles. Lead-Containing Surface Coatings/Lead-Based Paints/Lead-Bearing Substances (LCSCs/LBPs/LBSs) ^ Analytical Methodology Potential LCSCs/LBPs/LBSs were identified via visual identification. The representative, suspect surface coatings were then measured on-site through the use of a NITON XL x-ray fluorescence (XRF) spectrum analyzer, in accordance with the requirements of the manufacturer's performance characteristics sheet (PCS) for this instrument. For purposes of this survey, and in accordance with Title 8 of the California Code of Regulations, Section 1532.1 (8 CCR 1532.1) and Title 17 of the California Code of Regulations, Section 35001 et. seq. the XRF measurement data results were interpreted as follows: 1. Positive results (LBPs/LBSs) were determined when analytical results revealed a lead concentration of 1.0 milligrams per square centimeter (mg/cm2) or greater. 2. Positive results (LCSCs) were determined when analytical results revealed a lead concentration of 0.1 mg/cm2 or greater, up to 1.0 mg/cm2. 3. Negative results were determined when analytical results revealed a lead concentration of less than 0.1 mg/cm2 which is below the analytical sensitivity of the XRF measurement methodology. RESULTS Asbestos Survey A total of 79 bulk samples for the determination of asbestos content were collected from the subject site buildings on March 16and 17,2011. Based on the results of the asbestos survey of the subject building and laboratory analytical results, the following materials are considered to be ACMs. as defined by USEPA, and found to contain detectable concentrations ofl%OR GREATER OF ASBESTOS (locations, conditions, and estimated total quantity of materials are found in the Executive Summary): Calavera Treatment Plant 1.

Universal Waste Rule Survey Based on the results of visual identification, the following universal waste materials were observed at the subject site structures (locations and estimated total quantity of materials are found in the Executive Summary): 1. Florescent light tubes 2. Suspect PCB-containing light fixture ballasts 3. Halogen lights CONCLUSIONS/RECOMMENDATIONS Asbestos Survey The results of the asbestos survey indicate that ACMs are present at some of the subject site structures (see Executive Summary tables), which may be impacted by the impending demolition activities. At no time should the identified ACMs or ACCMs be drilled, cut, sanded, scraped or otherwise disturbed by untrained personnel. These materials should be removed prior to any activities which will impact these materials. Asbestos disturbance and/or removal operations must be conducted by a California Occupational Safety and Health Administration (Cal/OSHA)-registered and State licensed asbestos removal contractor. Disturbance and/or abatement operations should be performed under the direct observation of a California Certified Asbestos Consultant. Construction activities involving the potential for impacting ACMs should be conducted in accordance with the requirements of Title 8 of the California Code of Regulations, Section 1529 (8 CCR 1529). For all abatement activities which will involve the removal of at least 100 square feet of identified asbestos- containing materials, notification must be made to the San Diego Air Pollution Control District (SDAPCD). Notification to SDAPCD must be accomplished ten working days prior to the initiation of such activities. For abatement activities which will involve asbestos-related work of at least 100 square or linear feet, written notification must be made to Cal/OSHA. Notification to Cal/OSHA must be accomplished 24 hours prior to the initiation of such activities. Notification to employees and contractors working within the building should be made in accordance with the California Health and Safety Code, Section 25915 et.seq. and Proposition 65. Survey Report - Section 2 March 30, 2011 Calavera Treatment Plant Pa»e 5 Lead Testing Services The lead testing services revealed that building components with coatings defining them as LBPs. LBSs and LCSCs are present at some of the subject site structures, which may be impacted by the impending demolition activities. All demolition involving potential and identified lead-containing surfaces should be conducted in accordance with Title 8, California Code of Regulations, Section 1532.1 and 29 CFR 1926.62. In addition, all activities involving identified lead-based paints must be conducted in accordance with Title 17, California Code of Regulations, Division 1, Chapter 8, Sections 35001 through 36100, which proscribes the use of CDPH - certified workers, work practices, and other requirements. At present there is no state or federal regulation requiring mandatory lead removal or abatement prior to disturbance or demolition of structures with identified lead materials. However, there are applicable CaVOSHA worker protection and training requirements; Cal/EPA waste disposal requirements, CDPH requirements for public and residential buildings, and SB 460 lead hazard regulations that apply to lead-related construction activities, abatement activities and their associated wastes. The following is a brief discussion and summary of applicable regulatory requirements: * Cal/OSHA: Title 8, California Code of Regulation (CCR), Section 1532.1 {8 CCR 1532.1) governs occupational exposure to lead. This regulation requires that prior to initiation of certain activities, referred to as "trigger tasks", workers must be trained, medically evaluated, and properly fitted with respiratory protection, and protective clothing until statistically reliable personal eight-hour time weighted average (TWA) results indicate lead exposure levels below the Personal Exposure Limit (PEL) for each unique task which disturbs lead-based and lead-containing coatings. This process is known as a Negative Exposure Assessment or NBA. If the result of the exposure assessment is above' the Action Level (AL) additional monitoring is required and if the result is above the PEL additional exposure monitoring, worker protection (including respirator protection and PPE), training and medical requirements apply. However even where the NEA criteria is met, certain hazard communication training and work practice controls still apply where lead is disturbed. "Trigger tasks" are tasks that are assumed to exceed the PEL pending an exposure assessment and they encompass the majority of construction activities that disturb surface coatings. Examples of "trigger" tasks range from manual paint scraping as a lower expected exposure up to hot work and abrasive blasting as the highest expected exposures, and include any non-listed task that the employer determines may potentially expose employees to lead levels above the AL. NOTE - "OSHA does not consider any method that relies solely on the analysis of bulk materials or surface content of lead (or other toxic material) to be acceptable for safely predicting employee exposure to airborne contaminates. Without air monitoring results or without the benefit of historical or objective data (including air sampling which clearly demonstrates that the employee can not be exposed above the action level during any process, operation, or activity) the analysis of bulk or surface samples can not be used to determine employee exposure." OSHA Standard Interpretation 5/8/2000. Furthermore, OSHA states that these rales apply to "any detectable concentration of lead" without a specified detection level. Due to the Consumer Product Safety Commission currently allowing paint Survey Report - Section 2 March 30,2011 Calavera Treatment Plant Page 6 WINZLER<ScKELLY to contain up to 600 parts per million (ppm) of lead, the variation of lead content due to aging and weathering, and the variation of detection limits associated with both paint chip and XRF analysis, it is recommended that all painted or coated surfaces be treated as potentially containing lead. Clearly, positive analytical results by either method can be used to indicate that detectable lead is present but negative results cannot be interpreted as conclusively demonstrating the absence of lead. Analytical data of bulk paint/coating materials or surface content (by XRF) of lead can be helpful in evaluation of lead-related environmental risks in general but cannot be used to calculate worker exposures and are not a substitute for employee exposure monitoring. As a result of the above, any employee that works around potential lead-based or lead-containing coatings must have HAZCOM training and personal exposure air monitoring is additionally required for employees that disturb such coatings. Significant additional certification, notification, and work practices are required for materials found to be "lead-based". * Any welding, cutting or heating of metal surfaces containing surface coatings should be conducted in accordance with 29 CFR1926.354 and 8 CCR 1537. These regulations require surfaces covered with toxic preservatives, and in enclosed areas, be stripped of all toxic coatings for a distance of at least 4 inches, in all directions, from the area of heat application prior to the initiation of such heat application. » Cal/EPA through the Division of Toxic Substance Control (DTSC) regulates disposal of lead hazardous waste (Title 22 Division 4.5, Environmental Health Standards for the Management of Hazardous Waste). DTSC has issued guidance indicating that architectural debris with intact lead paint is normally expected to be handled as general construction waste. However, waste stream segregation and analysis is still required for all paint or coating debris regardless of if the paint or coating is intact on a building component or not. The resulting wastes may be hazardous under California and federal RCRA standards for lead and therefore require proper handling, packaging, labeling, and transportation under a proper manifest to a permitted hazardous waste storage, treatment and disposal facility. * CDPH: The State of California Department of Public Health (CDPH) has specific requirements (Title 17 Sections 35001 thru 36100 et. al.) for hazard assessment and work in public or residential structures. These regulations require special certifications, work practices, and notification for such activities. * Senate Bill 460 (SB 460): An act to amend Section 1941.1 of the Civil Code, and to amend Sections 17961, 17980, and 124130 of, and to add Sections 17920.10, 105251, 105252, 105253, 105254, 105255, 105256, and 105257 to, the Health and Safety Code, relating to lead abatement. This bill allows for fines and criminal penalties to be levied on any person who is found to have performed lead abatement without containment or created a measurable lead hazard based upon current CDPH standards. The testing for this determination can be initiated by any local or state building inspector, health department inspector, or other designated state or local official. A determination of a lead hazard is not solely based upon the lead content of the paint or coating and can be the result of the disturbance of such materials with low concentrations of lead. Written notification to Cal/OSHA must be accomplished should LBP activities involve more than 100 square or linear feet of removal in accordance with the requirements of 8 CCR 1532.1. Proper written notification to Survey Report - Section 2 March 30, 2011 Calavera Treatment Plant Page 7 CDPH may be required, depending upon the nature of the activity. Proper waste characterization and disposal of lead-containing materials and lead-contaminated debris should be conducted in accordance with Title 22 of the California Code of Regulations and the California Health and Safety Code, Section 25157.8. Universal Waste The hazardous material building survey revealed that universal waste materials are present at some of the subject site structures, which may be impacted by the impending demolition activities. Winzler & Kelly's limited spot checks indicated that PCB-containing light fixture ballasts are present in areas of the investigated facility; however, due to the limited nature of the random spot checks, Winzler & Kelly recommends that all light fixtures be visually inspected, prior to disposal, to determine if they contain PCBs. Those ballasts marked "No PCBs" or "PCB Free", should be considered as such. All potential and identified PCB-containing light fixture ballasts should be handled, collected, transported and disposed in accordance with the requirements of Title 22 of the California Code of Regulations, Section 67426.1 (22 CCR 67426.1). Fluorescent light tubes, mercury-containing thermostat switch capsules, and other Universal Waste Rule components should be handled in accordance with the requirements of Title 22 of the California Code of Regulations, Section 66273 et seq. (22 CCR 66273). It is the contractor's responsibly to confirm the hazardous material quantities present prior to initiating renovation or demolition activities at the subject buildings. Should materials similar to those identified in this report, or other forms of suspect hazardous materials be present or identified, maintenance personnel/contractors should be instructed to immediately cease work activities which may initiate a fiber release episode, and notify the appropriate management personnel.

The discharger shall ensure that the SWPPPs for all traditional project sites are developed and amended or revised by a QSD. The SWPPP shall be designed to address the following objectives: 1. All pollutants and their sources, including sources of sediment associated with construction, construction site erosion and all other activities associated with construction activity are controlled. 2. Where not otherwise required to be under a Regional Water Board permit, all non-storm water discharges are identified and either eliminated, controlled, or treated. 3. Site BMPs are effective and result in the reduction or elimination of pollutants in storm water discharges and authorized non-storm water discharges from construction activity to the BAT/BCT standard. 4. Calculations and design details as well as BMP controls for site run-on are complete and correct. 5. Stabilization BMPs installed to reduce or eliminate pollutants after construction are completed. 6. Identify post-construction BMPs which are those measures to be installed during construction that are intended to reduce or eliminate pollutants after construction is completed (post-construction BMPs are required for all sites by Section XIII.B) Note that post-construction BMPs should be developed early in the project planning/design process and reports or drawings related to permanent BMP design should be referenced as needed. 7. Identify and provide methods to implement BMP inspection, visual monitoring, Rain Event Action Plan (REAP) and Construction Site Monitoring Program (CSMP) requirements to comply with the General Permit.

Signed Certification Statement This SWPPP is also required to be filed electronically and has been submitted to the SWRCB as a PRO. Storm Water Pollution Prevention Plan 4 Calavera Hills Sewer Treatment Plant Demolition 1.3 SWPPP Availability and Implementation The General Permit (Section XIV.C) requires the SWPPP be available at the construction site during working hours while construction is occurring and shall be made available upon request by a State or Municipal inspector. When the original SWPPP is retained by a crewmember in a construction vehicle and is not currently at the construction site, current copies of the BMPs and map/drawings will be left with the field crew and the original SWPPP shall be made available via a request by radio/telephone. The SWPPP shall be implemented concurrently with the start of ground disturbing activities. 1.4 SWPPP Amendments The General Permit requires that SWPPP be amended or revised by a QSD (Section XIV.A) and that the SWPPP include a listing of the date of initial preparation and the date of each amendment. Amendments must be signed by a QSD (Section VII.B.6). It is recommended that all amendments be dated, directly attached to the SWPPP, and logged in SWPPP Appendix C). The SWPPP must be revised or modified: • To reflect modifications to stormwater control measures made in response to a change in design, construction, operation, or maintenance at the construction site that has or could have a significant effect on the discharge of pollutants to the waters of the United States that has not been previously addressed in the SWPPP. • If during inspections or investigations by site staff, or by local, state, tribal or federal officials, it is determined that the existing stormwater controls are ineffective in eliminating or significantly minimizing pollutants in stormwater discharges from the construction site. • Based on the results of an inspection, as necessary to properly document additional or modified BMPs designed to correct problems identified. Revisions to the SWPPP must be completed in a timely manner. Amendments to the SWPPP will be prepared and certified by the QSD; documented on the amendment form; and tracked on the amendment log. Fill out the forms completely;' document the reason for the amendment and how it modifies current conditions. Cross out the old information in the SWPPP that is being amended and note the amendment number that replaces the information next to the item. 1.5 Retention of Records The General Permit (Sections I.J.69 and IV.G) requires that all dischargers maintain a paper or electronic copy of all required records for three years from the date generated or date submitted, whichever is last. These records must be available at the construction site until construction is completed. The discharger shall furnish the RWQCB, SWRCB, or US Environmental Protection Agency (EPA), within a reasonable time, any requested information to determine compliance with this General Permit. State in the SWPPP where documents will be kept and how these requirements will be met. RWQCB's may require records to be retained for longer periods. 1.6 Required Non-Compliance Reporting The General Permit identifies several areas of non-compliance reporting. It is the responsibility of the permittee to properly document reportable discharges or other violations of the General Permit. Exceedances and violations will be reported using the SMARTS database and include the following: Storm Water Pollution Prevention Plan 5 Calavera Hills Sewer Treatment Plant Demolition • Numeric Action Level (NAL) exceedances (NAL Exceedance Report upon request of the RWQCB) (Only for Risk Levels 2 and 3). • Numeric Effluent Limitation (NEL) Violation Report (Only for Risk Level 3). • Self-reporting of any other discharge violations or to comply with RWQCB enforcement actions. • Discharges which contain a hazardous substance in excess of reportable quantities established in 40 CFR §§ 117.3 and 302.4 unless a separate NPDES Permit has been issued to regulate those discharges. In the event of the exceedance of a NAL, document the subsequent site evaluation in the SWPPP (Section V.C.4). It is recommended that documentation of all reportable exceedances be included in the SWPPP. Include the results of an NAL exceedance site evaluation along with other non- compliance events in SWPPP Appendix D. 1.7 Annual Report Permittee will prepare, certify, and electronically submit an Annual Report no later than September 1 of each year, commencing 2011. Reporting requirements are identified in Section XVI of the General Permit and include providing a summary of: 1. A summary and evaluation of all sampling and analysis results, including copies of laboratory reports. 2. The analytical method(s), method report unit(s), and method detection limit(s) of each analytical parameter (analytical results that are less than the method detection limit shall be reported as "less than the method detection limit"). 3.

On site inspections will include observations for non-stormwater discharges and activities with a potential to cause discharges will be monitored and controlled as needed. Authorized non-storm water discharges include: • Discharges from fire-fighting activities. Storm Water Pollution Prevention Plan 13 Calavera Hills Sewer Treatment Plant Demolition • Fire hydrant flushing. • Waters used to wash vehicles where detergents are not used. • Water used to control dust. • Potable water including uncontaminated water line flushing. • Routine external building wash down that does not use detergents. • Pavement wash waters where spills or leaks of toxic or hazardous materials have not occurred (unless all spilled material has been removed) and where detergents are not used. • Uncontaminated air conditioning or compressor condensate. • Uncontaminated ground water or spring water. • Foundation or footing drains where flows are not contaminated with process materials such as solvents. • Uncontaminated excavation dewatering. • Landscape irrigation. The discharge of non-storm water is authorized under the following conditions: • The discharge does not cause or contribute to a violation of any water quality standard. • The discharge does not violate any provision of the General Permit. • The discharge is not prohibited by the applicable Basin Plan • The SWPPP includes and implements BMPs required by the General Permit to prevent or reduce the contact of the non-stormwater discharge with construction materials or equipment • The discharge does not contain toxic constituents in toxic amounts or (other) significant quantities of pollutants. • The sampling information is reported in the Annual Report. If any of the above conditions are not satisfied, the discharge is not authorized by the CA CGP and not permitted by this SWPPP. Notify the Regional Water Board of any anticipated non-storm water discharges not already authorized by CA CGP or another NPDES permit, to determine whether a separate NPDES permit is necessary. 2.6.1 Expected Non-Stormwater Discharges and Controls Allowable non stormwater discharges anticipated to be encountered in this project include the following: Waters to Control Dust Dust control will be implemented when wind exceed 15 MPH or when there is visible dust generated from the site via a small diameter (3/4" to 1") fire or garden hose or with a water truck depending on Storm Water Pollution Prevention Plan 14 Calavera Hills Sewer Treatment Plant Demolition the area being serviced. All efforts will be made not to over apply the water spray to avoid any surface run off. In the event there is surface run off it will be controlled with the use of perimeter silt fence. Any discharges from the property will be observed and operations ceased if levels of sediment in the discharge pose a negative impact on the drainage system or receiving waters. Responsible party: QSP & all trades are responsible to control dust for their operations. Uncontaminated air conditioning or compressor condensate The discharges from air conditioning condensate is expected to be seasonal and at a minimum. Waters will be diverted into the landscaped and permeable areas so as not to be discharged into the storm drain system. The discharges will be monitored and if there is a chance of discharge to the storm drain system, BMPs will be installed to divert the water to a permeable area. Responsible party: QSP Landscape Irrigation Irrigation water will be sprayed on permeable surfaces only. Landscape irrigation areas will be monitored to prevent over watering. Watering times and schedules will be adjusted in the event there is surface run off from the irrigated areas. Responsible party: QSP & Landscape and irrigation contractor. Any changes in construction that will produce other allowable non storm water discharges will be identified. The SWPPP will be amended and the appropriate erosion and sediment controls will be implemented. Compliance with the GCP does not relieve the project of other potentially applicable discharge requirements of the various other plan requirements such as but not limited to the Basin Plan, ADBS, or adopted TMDL allocations.

File NOT Storm Water Pollution Prevention Plan 22 Calavera Hills Sewer Treatment Plant Demolition 3.2 Erosion and Sediment Control 3.2.1 Erosion Control BMPs EC-1 Scheduling Description and Purpose Scheduling Scheduling is an erosion control BMP that consists of the development of a written plan that includes sequencing of construction activities and the implementation of BMPs such as erosion control and sediment control while taking local climate (rainfall, wind, etc.) into consideration. The purpose is to reduce the amount and duration of soil exposed to erosion by wind, rain, runoff, and vehicle tracking, and to perform the construction activities and control practices in accordance with the planned schedule. Suitable Applications: Proper sequencing of construction activities to reduce erosion potential should be incorporated into the schedule of every construction project especially during rainy season. Implementation: 1. If the actual start dates for construction activities vary significantly from the tentative schedule the construction schedule in the SWPPP should be reviewed and updated accordingly. 2. Avoid earth disturbing activity during rainy periods. Schedule major grading operations during dry months when practical. 3. Incorporate Sequence of Construction Activities and Associated BMPs with the implementation and deployment of: • Erosion control BMPs • Sediment control BMPs • Tracking control BMPs • Wind erosion control BMPs • Non-stormwater BMPs • Waste management and materials pollution control BMPs 4. Sequence trenching activities so that most open portions are closed before new trenching begins. 5. Incorporate staged seeding and re-vegetation of graded slopes as work progresses. 6. Schedule establishment of permanent vegetation during appropriate planting time for specified vegetation. 7. Regularly monitor the weather forecast for rainfall. Storm Water Pollution Prevention Plan 23 Calavera Hills Sewer Treatment Plant Demolition 8. When rainfall is predicted, adjust the construction schedule to allow the implementation of additional soil stabilization and sediment treatment controls on all disturbed areas prior to the onset of rain. 9. Apply permanent erosion controls to areas deemed substantially complete in accordance with stabilization requirements in the applicable California Construction General Permit. Maintenance and Inspection: 1. QSD to update the SWPPP with appropriate BMPs if the original schedule has significantly changed or if a change in the timing or selection of BMPs is warranted. WE-1 Wind Erosion Control Description and Purpose Wind erosion or dust control consists of applying water, soil cover, or dust palliatives as necessary to prevent or alleviate dust nuisance and soil transport generated by construction activities. Covering small stockpiles or disturbed areas is an alternative to applying water or dust palliatives. Materials applied as temporary soil stabilizers and soil binders also generally provide wind erosion control benefits. Suitable Applications Most BMPs that provide protection against water-based erosion will also protect against wind-based erosion and dust control requirements required by other agencies will generally meet wind erosion control requirements for water quality protection. Wind erosion control BMPs are suitable during the following construction activities: 1. Construction vehicle traffic on unpaved roads 2. Drilling and blasting activities 3. Soils and debris storage piles 4. Batch drop from front-end loaders 5. Areas with unstabilized soil 6. Final grading/site stabilization Implementation (See dust control practices grid for dust control practices applicable to this site) Many local agencies including air quality management districts and municipalities require dust control in order to comply with local nuisance laws, opacity laws (visibility impairment) and the requirements of the Clean Air Act. General 1. Install a stabilized entry to access points where unpaved traffic surfaces adjoin paved roads. 2. Provide covers for haul trucks transporting materials that contribute to dust. 3. Apply water or chemical stabilization during construction as needed to control dust. 4. Suppress dust when loading trucks with soil, dirt, debris or other construction materials Storm Water Pollution Prevention Plan 24 Calavera Hills Sewer Treatment Plant Demolition 5. Avoid over application of water or chemicals to the extent that it creates a non-stormwater discharge 6. Provide for rapid clean up of sediments deposited on paved roads. 7. Stabilize stockpiles per WM-3 Stockpile Management. 8. Stabilize inactive disturbed areas with mulch, vegetation or chemical stabilization methods. 9. For chemical stabilization, there are many products available for chemically stabilizing gravel roadways and stockpiles. If chemical stabilization is used, the chemicals should not create any adverse effects on stormwater, plant life, or groundwater. 10. If reclaimed waste water is used as a dust control measure, the sources and discharge must meet California Department of Health Services water reclamation criteria and the Regional Water Quality Control Board requirements. Non-potable water should not be conveyed in tanks or drain pipes that will be used to convey potable water and there should be no connection between potable and non-potable supplies. Non-potable tanks, pipes, and other conveyances should be marked, "NON-POTABLE WATER - DO NOT DRINK." Maintenance and Inspection: 1. Verify that activity-based BMPs are installed and/or available prior to and during the commencement of dust generating activity. 2. Check stabilized areas ands stockpiles for the implementation of adequate dust controls. 3. Apply water, stabilization, or dusts suppressant if dust is being generated or additional measures are needed. 3.2.2 Sediment Control BMPs TC-1 Stabilized Construction Entrance/Exit Description and Purpose A stabilized construction access is defined by a point of entrance/exit to a construction site that is stabilized to reduce the tracking of mud and dirt onto public roads by construction vehicles. Suitable Applications Use at construction sites: 1. Where dirt or mud can be tracked onto public roads. 2. Adjacent to water bodies. 3. Where poor soils are encountered. 4. Where dust is a problem during dry weather conditions. Implementation Design and Layout for site entrance 1. Construct on level ground where possible. Storm Water Pollution Prevention Plan 25 Calavera Hills Sewer Treatment Plant Demolition 2. Select 1.5 in. angular diameter stones. 3. Use minimum depth of stones of 6-8 in. or as recommended by soils engineer. 4. Construct length of 50 ft minimum, and 30 ft minimum width. 5. Rumble racks constructed of steel panels with ridges and installed in the stabilized entrance/exit will help remove additional sediment and to keep adjacent streets clean. 6. Provide ample turning radii as part of the entrance. 7. Limit the points of entrance/exit to the construction site. 8. Limit speed of vehicles to control dust. 9. Grade each construction entrance/exit to prevent runoff from leaving the construction site. 10. Route runoff from stabilized entrances/exits through a sediment trapping device before discharge. 11. Design stabilized entrance/exit to support heaviest vehicles and equipment that will use it. 12. Select construction access stabilization (aggregate, asphaltic concrete, concrete) based on longevity, required performance, and site conditions. Do not use asphalt concrete (AC) grindings for stabilized construction access/roadway. 13. If aggregate is selected, place crushed aggregate over geotextile fabric to at least 12 in. depth, or place aggregate to a depth recommended by a geotechnical engineer. A crushed aggregate 1.5 in. or greater. 14. Designate combination or single purpose entrances and exits to the construction site. 15. Require that all associates, subcontractors, and suppliers utilize the stabilized construction access. 16. Implement SE-7, Street Sweeping and Vacuuming, as needed. Maintenance and Inspection: 1. Verify that activity-based BMPs are in place prior to the commencement of associated activities. 2. Inspect stabilized exits during regular weekly, pre-rain, extended event, and post rain event inspections. 3. Remove aggregate, separate and dispose of sediment if construction, entrance/exit is clogged with sediment. 4. Check for damage and repair as needed. 5. Replace gravel material when surface voids are visible. 6. Remove all sediment deposited on paved roadways within 24 hours. 7. Remove gravel and filter fabric at completion of construction.

Storm Water Pollution Prevention Plan 30 Project Name SECTION 4.0 BMP INSPECTION, MAINTENANCE, AND RAIN EVENT ACTION PLANS 4.1 BMP Inspection and Maintenance The General Permit requires (Attachments C, D, E; Section G.5) that completed inspection checklists be maintained with the onsite SWPPP. In general the information required to be recorded for BMP/facility inspections includes: the date of the inspection, weather information, site information, observations, descriptions of the inspection BMPs and any deficiencies, and the corrective actions that were taken such as BMPs that were fixed or additional BMPs that were implemented, and the inspectors printed name, title, and signature. The required frequency of BMP inspections depends on the type of BMP that is implemented. The General Permit (Attachments C, D, E; ; Section G.2) requires routine weekly inspections and daily inspections during rain events of all BMPs (for all Risk Levels); however, some BMPs (e.g. tracking controls; Attachments D & E, Section E.7) may require daily monitoring. BMPs must be maintained regularly based on permit-required inspections and observations during the course of normal construction activities. A daily log shall be maintained reflecting that all BMPs were visually inspected. The General Permit requires discharges to begin implementing corrective actions within 72 hours for deficiencies identified during inspections (Attachments C, D, E; Section G.3). SWPPP amendments should be prepared by the QSD if warranted by the problem encountered and corrective action required. Storm Water Pollution Prevention Plan 31 Project Name 4.2 Rain Event Action Plans REAP's developed by a QSP, are only required for all Risk Level 2 and 3 dischargers for each construction phase. The SWPPP has included a REAP template, but the QSP will need to customize them for each rain event. Include site-specific REAP templates for each applicable phase of the project in SWPPP Appendix J. Completed REAPs must be maintained on site. It is recommended that they be maintained with the SWPPP or in an accompanying binder/folder that is referenced in the SWPPP. The QSP must develop the REAP 48-hours in advance of any precipitation event forecast to have a 50% or greater chance of producing precipitation in the project area. The REAP must be on site and be implemented 24 hours in advance of any of the predicted precipitation event. The REAP is designed to protect all exposed portions of project sites and to ensure that the discharger has adequate materials, staff, and time to implement erosion and sediment control measures that are intended to reduce the amount of sediment and other pollutants that could be generated during the rain event.

CAS000002 WASTE DISCHARGE REQUIREMENTS FOR DISCHARGES OF STORM WATER RUNOFF ASSOCIATED WITH CONSTRUCTION AND LAND DISTURBANCE ACTIVITIES I. FINDINGS A. General Findings The State Water Resources Control Board (State Water Board) finds that: 1. The federal Clean Water Act (CWA) prohibits certain discharges of storm water containing pollutants except in compliance with a National Pollutant Discharge Elimination System (NPDES) permit (Title 33 United States Code (U.S.C.) §§ 1311 and 1342(p); also referred to as Clean Water Act (CWA) §§ 301 and 402(p)). The U.S. Environmental Protection Agency (U.S. EPA) promulgates federal regulations to implement the CWA's mandate to control pollutants in storm water runoff discharges. (Title 40 Code of Federal Regulations (C.F.R.) Parts 122, 123, and 124). The federal statutes and regulations require discharges to surface waters comprised of storm water associated with construction activity, including demolition, clearing, grading, and excavation, and other land disturbance activities (except operations that result in disturbance of less than one acre of total land area and which are not part of a larger common plan of development or sale), to obtain coverage under an NPDES permit. The NPDES permit must require implementation of Best Available Technology Economically Achievable (BAT) and Best Conventional Pollutant Control Technology (BCT) to reduce or eliminate pollutants in storm water runoff. The NPDES permit must also include additional requirements necessary to implement applicable water quality standards. 2. This General Permit authorizes discharges of storm water associated with construction activity so long as the dischargers comply with all requirements, provisions, limitations and prohibitions in the permit. In addition, this General Permit regulates the discharges of storm water associated with construction activities from all Linear Underground/Overhead Projects resulting in the disturbance of greater than or equal to one acre (Attachment A). 2009-0009-DWQ 1 September 02,2009 Order 3. This General Permit regulates discharges of pollutants in storm water associated with construction activity (storm water discharges) to waters of the United States from construction sites that disturb one or more acres of land surface, or that are part of a common plan of development or sale that disturbs more than one acre of land surface. 4. This General Permit does not preempt or supersede the authority of local storm water management agencies to prohibit, restrict, or control storm water discharges to municipal separate storm sewer systems or other watercourses within their jurisdictions. 5. This action to adopt a general NPDES permit is exempt from the provisions of Chapter 3 of the California Environmental Quality Act (CEQA) (Public Resources Code Section 21100, et seq.), pursuant to Section 13389 of the California Water Code. 6. Pursuant to 40 C.F.R. § 131.12 and State Water Board Resolution No. 68-16.1 which incorporates the requirements of § 131.12 where applicable, the State Water Board finds that discharges in compliance with this General Permit will not result in the lowering of water quality standards, and are therefore consistent with those provisions. Compliance with this General Permit will result in improvements in water quality. 7. This General Permit serves as an NPDES permit in compliance with CWA § 402 and will take effect on July 1, 2010 by the State Water Board provided the Regional Administrator of the U.S. EPA has no objection. If the U.S. EPA Regional Administrator objects to its issuance, the General Permit will not become effective until such objection is withdrawn. 8. Following adoption and upon the effective date of this General Permit, the Regional Water Quality Control Boards (Regional Water Boards) shall enforce the provisions herein. 9. Regional Water Boards establish water quality standards in Basin Plans. The State Water Board establishes water quality standards in various statewide plans, including the California Ocean Plan. U.S. EPA establishes water quality standards in the National Toxic Rule (NTR) and the California Toxic Rule (CTR). 1 Resolution No. 68-16 generally requires that existing water quality be maintained unless degradation is justified based on specific findings. 2009-0009-DWQ 2 September 02,2009 Order 10. This General Permit does not authorize discharges of fill or dredged material regulated by the U.S. Army Corps of Engineers under CWA § 404 and does not constitute a waiver of water quality certification under CWA § 401. 11 .The primary storm water pollutant at construction sites is excess sediment. Excess sediment can cloud the water, which reduces the amount of sunlight reaching aquatic plants, clog fish gills, smother aquatic habitat and spawning areas, and impede navigation in our waterways. Sediment also transports other pollutants such as nutrients, metals, and oils and greases. 12. Construction activities can impact a construction site's runoff sediment supply and transport characteristics. These modifications, which can occur both during and after the construction phase, are a significant cause of degradation of the beneficial uses established for water bodies in California. Dischargers can avoid these effects through better construction site design and activity practices. 13.This General Permit recognizes four distinct phases of construction activities. The phases are Grading and Land Development Phase, Streets and Utilities Phase, Vertical Construction Phase, and Final Landscaping and Site Stabilization Phase. Each phase has activities that can result in different water quality effects from different water quality pollutants. This General Permit also recognizes inactive construction as a category of construction site type. 14. Compliance with any specific limits or requirements contained in this General Permit does not constitute compliance with any other applicable requirements. 15. Following public notice in accordance with State and Federal laws and regulations, the State Water Board heard and considered all comments and testimony in a public hearing on 06/03/2009. The State Water Board has prepared written responses to all significant comments. 16. Construction activities obtaining coverage under the General Permit may have multiple discharges subject to requirements that are specific to general, linear, and/or active treatment system discharge types. 17.The State Water Board may reopen the permit if the U.S. EPA adopts a final effluent limitation guideline for construction activities. 2009-0009-DWQ 3 September 02,2009 Order B. Activities Covered Under the General Permit 18. Any construction or demolition activity, including, but not limited to, clearing, grading, grubbing, or excavation, or any other activity that results in a land disturbance of equal to or greater than one acre. 19. Construction activity that results in land surface disturbances of less than one acre if the construction activity is part of a larger common plan of development or the sale of one or more acres of disturbed land surface. 20. Construction activity related to residential, commercial, or industrial development on lands currently used for agriculture including, but not limited to, the construction of buildings related to agriculture that are considered industrial pursuant to U.S. EPA regulations, such as dairy barns or food processing facilities. 21. Construction activity associated with Linear Underground/Overhead Utility Projects (LUPs) including, but not limited to, those activities necessary for the installation of underground and overhead linear facilities (e.g., conduits, substructures, pipelines, towers, poles, cables, wires, connectors, switching, regulating and transforming equipment and associated ancillary facilities) and include, but are not limited to, underground utility mark-out, potholing, concrete and asphalt cutting and removal, trenching, excavation, boring and drilling, access road and pole/tower pad and cable/wire pull station, substation construction, substructure installation, construction of tower footings and/or foundations, pole and tower installations, pipeline installations, welding, concrete and/or pavement repair or replacement, and stockpile/borrow locations. 22. Discharges of sediment from construction activities associated with oil and gas exploration, production, processing, or treatment operations or transmission facilities.2 23. Storm water discharges from dredge spoil placement that occur outside of U.S. Army Corps of Engineers jurisdiction (upland sites) and that disturb one or more acres of land surface from construction activity are covered by this General Permit. Construction sites that intend to disturb one or more acres of land within the jurisdictional boundaries of a CWA § 404 permit should contact the appropriate Regional Water Board to determine whether this permit applies to the site. 2 Pursuant to the Ninth Circuit Court of Appeals' decision in NRDC v. EPA (9th Cir. 2008) 526 F.3d 591, and subsequent denial of the U.S. EPA's petition for reconsideration in November 2008, oil and gas construction activities discharging storm water contaminated only with sediment are no longer exempt from the NPDES program. 2009-0009-DWQ 4 September 02,2009 Order C. Activities Not Covered Under the General Permit 24. Routine maintenance to maintain original line and grade, hydraulic capacity, or original purpose of the facility. 25. Disturbances to land surfaces solely related to agricultural operations such as disking, harrowing, terracing and leveling, and soil preparation. 26. Discharges of storm water from areas on tribal lands; construction on tribal lands is regulated by a federal permit. 27.Construction activity and land disturbance involving discharges of storm water within the Lake Tahoe Hydrologic Unit. The Lahontan Regional Water Board has adopted its own permit to regulate storm water discharges from construction activity in the Lake Tahoe Hydrologic Unit (Regional Water Board 6SLT). Owners of construction sites in this watershed must apply for the Lahontan Regional Water Board permit rather than the statewide Construction General Permit. 28. Construction activity that disturbs less than one acre of land surface, and that is not part of a larger common plan of development or the sale of one or more acres of disturbed land surface. 29. Construction activity covered by an individual NPDES Permit for storm water discharges. 30. Discharges from small (1 to 5 acre) construction activities with an approved Rainfall Erosivity Waiver authorized by U.S. EPA Phase II regulations certifying to the State Board that small construction activity will occur only when the Rainfall Erosivity Factor is less than 5 ("R" in the Revised Universal Soil Loss Equation). 31. Landfill construction activity that is subject to the Industrial General Permit. 32. Construction activity that discharges to Combined Sewer Systems. 33. Conveyances that discharge storm water runoff combined with municipal sewage. 34. Discharges of storm water identified in CWA § 402(/)(2), 33 U.S.C. § 1342(/)(2). 2009-0009-DWQ 5 September 02,2009 Order 35. Discharges occurring in basins that are not tributary or hydrologically connected to waters of the United States (for more information contact your Regional Water Board). D. Obtaining and Modifying General Permit Coverage 36.This General Permit requires all dischargers to electronically file all Permit Registration Documents (PRDs), Notices of Termination (NOT), changes of information, annual reporting, and other compliance documents required by this General Permit through the State Water Board's Storm water Multi-Application and Report Tracking System (SMARTS) website. 37. Any information provided to the Regional Water Board shall comply with the Homeland Security Act and any other federal law that concerns security in the United States; any information that does not comply should not be submitted. 38. This General Permit grants an exception from the Risk Determination requirements for existing sites covered under Water Quality Orders No. 99-08-DWQ, and No. 2003-0007-DWQ. For certain sites, adding additional requirements may not be cost effective. Construction sites covered under Water Quality Order No. 99-08-DWQ shall obtain permit coverage at the Risk Level 1. LUPs covered under Water Quality Order No. 2003-0007-DWQ shall obtain permit coverage as a Type 1 LUP. The Regional Water Boards have the authority to require Risk Determination to be performed on sites currently covered under Water Quality Orders No. 99-08-DWQ and No. 2003-0007-DWQ where they deem it necessary. The State Water Board finds that there are two circumstances when it may be appropriate for the Regional Water Boards to require a discharger that had filed an NOI under State Water Board Order No. 99-08-DWQ to recalculate the site's risk level. These circumstances are: (1) when the discharger has a demonstrated history of noncompliance with State Water Board Order No. 99-08- DWQ or; (2) when the discharger's site poses a significant risk of causing or contributing to an exceedance of a water quality standard without the implementation of the additional Risk Level 2 or 3 requirements. E. Prohibitions 39. All discharges are prohibited except for the storm water and non-storm water discharges specifically authorized by this General Permit or another NPDES permit. Non-storm water discharges include a wide variety of sources, including improper dumping, spills, or leakage from storage tanks or transfer areas. Non-storm water discharges may 2009-0009-DWQ 6 September 02,2009 Order contribute significant pollutant loads to receiving waters. Measures to control spills, leakage, and dumping, and to prevent illicit connections during construction must be addressed through structural as well as non-structural Best Management Practices (BMPs)3. The State Water Board recognizes, however, that certain non-storm water discharges may be necessary for the completion of construction. 40. This General Permit prohibits all discharges which contain a hazardous substance in excess of reportable quantities established in 40 C.F.R. §§ 117.3 and 302.4, unless a separate NPDES Permit has been issued to regulate those discharges. 41.This General Permit incorporates discharge prohibitions contained in water quality control plans, as implemented by the State Water Board and the nine Regional Water Boards. 42. Pursuant to the Ocean Plan, discharges to Areas of Special Biological Significance (ASBS) are prohibited unless covered by an exception that the State Water Board has approved. 43. This General Permit prohibits the discharge of any debris4 from construction sites. Plastic and other trash materials can cause negative impacts to receiving water beneficial uses. The State Water Board encourages the use of more environmentally safe, biodegradable materials on construction sites to minimize the potential risk to water quality. F. Training 44. In order to improve compliance with and to maintain consistent enforcement of this General Permit, all dischargers are required to appoint two positions - the Qualified SWPPP Developer (QSD) and the Qualified SWPPP Practitioner (QSP) - who must obtain appropriate training. Together with the key stakeholders, the State and Regional Water Boards are leading the development of this curriculum through a collaborative organization called The Construction General Permit (CGP) Training Team. 45. The Professional Engineers Act (Bus. & Prof. Code section 6700, et seq.) requires that all engineering work must be performed by a California licensed engineer. 3 BMPs are scheduling of activities, prohibitions of practices, maintenance procedures, and other management practices to prevent or reduce the discharge of pollutants to waters of the United States. BMPs also include treatment requirements, operating procedures, and practice to control site runoff, spillage or leaks, sludge or waste disposal, or drainage from raw material storage. 4 Litter, rubble, discarded refuse, and remains of destroyed inorganic anthropogenic waste. 2009-0009-DWQ 7 September 02,2009 Order G. Determining and Reducing Risk 46. The risk of accelerated erosion and sedimentation from wind and water depends on a number of factors, including proximity to receiving water bodies, climate, topography, and soil type. 47.This General Permit requires dischargers to assess the risk level of a site based on both sediment transport and receiving water risk. This General Permit contains requirements for Risk Levels 1, 2 and 3, and LUP Risk Type 1, 2, and 3 (Attachment A). Risk levels are established by determining two factors: first, calculating the site's sediment risk; and second, receiving water risk during periods of soil exposure (i.e. grading and site stabilization). Both factors are used to determine the site-specific Risk Level(s). LUPs can be determined to be Type 1 based on the flowchart in Attachment A.1. 48. Although this General Permit does not mandate specific setback distances, dischargers are encouraged to set back their construction activities from streams and wetlands whenever feasible to reduce the risk of impacting water quality (e.g., natural stream stability and habitat function). Because there is a reduced risk to receiving waters when setbacks are used, this General Permit gives credit to setbacks in the risk determination and post-construction storm water performance standards. The risk calculation and runoff reduction mechanisms in this General Permit are expected to facilitate compliance with any Regional Water Board and local agency setback requirements, and to encourage voluntary setbacks wherever practicable. 49. Rain events can occur at any time of the year in California. Therefore, a Rain Event Action Plan (REAP) is necessary for Risk Level 2 and 3 traditional construction projects (LUPs exempt) to ensure that active construction sites have adequate erosion and sediment controls implemented prior to the onset of a storm event, even if construction is planned only during the dry season. 50. Soil particles smaller than 0.02 millimeters (mm) (i.e., finer than medium silt) do not settle easily using conventional measures for sediment control (i.e., sediment basins). Given their long settling time, dislodging these soils results in a significant risk that fine particles will be released into surface waters and cause unacceptable downstream impacts. If operated correctly, an Active Treatment System (ATS5) can prevent or reduce the release of fine particles from construction sites. 5 An ATS is a treatment system that employs chemical coagulation, chemical flocculation, or electro coagulation in order to reduce turbidity caused by fine suspended sediment. 2009-0009-DWQ 8 September 02,2009 Order Use of an ATS can effectively reduce a site's risk of impacting receiving waters. 51. Dischargers located in a watershed area where a Total Maximum Daily Load (TMDL) has been adopted or approved by the Regional Water Board or U.S. EPA may be required by a separate Regional Water Board action to implement additional BMPs, conduct additional monitoring activities, and/or comply with an applicable waste load allocation and implementation schedule. Such dischargers may also be required to obtain an individual Regional Water Board permit specific to the area. H. Effluent Standards 52. The State Water Board convened a blue ribbon panel of storm water experts that submitted a report entitled, "The Feasibility of Numeric Effluent Limits Applicable to Discharges of Storm Water Associated with Municipal, Industrial and Construction Activities," dated June 19, 2006. The panel concluded that numeric limits or action levels are technically feasible to control construction storm water discharges, provided that certain conditions are considered. The panel also concluded that numeric effluent limitations (NELs) are feasible for discharges from construction sites that utilize an ATS. The State Water Board has incorporated the expert panel's suggestions into this General Permit, which includes both numeric action levels (NALs) and NELs for pH and turbidity, and special numeric limits for ATS discharges. Numeric Effluent Limitations 53. Discharges of storm water from construction activities may become contaminated from alkaline construction materials resulting in high pH (greater than pH 7). Alkaline construction materials include, but are not limited to, hydrated lime, concrete, mortar, cement kiln dust (CKD), Portland cement treated base (CTB), fly ash, recycled concrete, and masonry work. This General Permit includes an NEL for pH (6.0-9.0) that applies only at sites that exhibit a "high risk of high pH discharge." A "high risk of high pH discharge" can occur during the complete utilities phase, the complete vertical build phase, and any portion of any phase where significant amounts of materials are placed directly on the land at the site in a manner that could result in significant alterations to the background pH of any discharges. 54. For Risk Level 3 discharges, this General Permit establishes technology-based, numeric effluent limitations (NELs) for turbidity of 500 NTU. Exceedances of the turbidity NEL constitutes a violation of this General Permit. 2009-0009-DWQ 9 September 02,2009 Order 55. This General Permit establishes a 5 year, 24 hour (expressed in inches of rainfall) Compliance Storm Event exemption from the technology- based NELs for Risk Level 3 dischargers. Determining Compliance with Numeric Limitations 56.This General Permit sets a pH NAL of 6.5 to 8.5, and a turbidity NAL of 250 NTU. The purpose of the NAL and its associated monitoring requirement is to provide operational information regarding the performance of the measures used at the site to minimize the discharge of pollutants and to protect beneficial uses and receiving waters from the adverse effects of construction-related storm water discharges. The NALs in this General Permit for pH and turbidity are not directly enforceable and do not constitute NELs. 57. This General Permit requires dischargers with NAL exceedances to immediately implement additional BMPs and revise their Storm Water Pollution Prevention Plans (SWPPPs) accordingly to either prevent pollutants and authorized non-storm water discharges from contaminating storm water, or to substantially reduce the pollutants to levels consistently below the NALs. NAL exceedances are reported in the State Water Boards SMARTS system, and the discharger is required to provide an NAL Exceedance Report when requested by a Regional Water Board. 58. If run-on is caused by a forest fire or any other natural disaster, then NELs do not apply. 59. Exceedances of the NELs are a violation of this Permit. This General Permit requires dischargers with NEL exceedances to implement additional monitoring, BMPs, and revise their SWPPPs accordingly. Dischargers are required to notify the State and Regional Water Boards of the violation through the State Water Boards SMARTs system, and provide an NEL Violation Report sharing additional information concerning the NEL exceedance. I. Receiving Water Limitations 60. This General Permit requires all enrolled dischargers to determine the receiving waters potentially affected by their discharges and to comply with all applicable water quality standards, including any more stringent standards applicable to a water body. J. Sampling, Monitoring, Reporting and Record Keeping 61 .Visual monitoring of storm water and non-storm water discharges is required for all sites subject to this General Permit. 2009-0009-DWQ 10 September 02,2009 Order 62. Records of all visual monitoring inspections are required to remain on- site during the construction period and for a minimum of three years. 63. For all Risk Level 3 and Risk Level 2 sites, this General Permit requires effluent monitoring for pH and turbidity. Sampling, analysis and monitoring requirements for effluent monitoring for pH and turbidity are contained in this General Permit. 64. Risk Level 3 sites in violation of the Numeric Effluent Limitations contained in this General Permit and with direct discharges to receiving water are required to conduct receiving water monitoring. 65. For Risk Level 3 sites larger than 30 acres and with direct discharges to receiving waters, this General Permit requires bioassessment sampling before and after site completion to determine if significant degradation to the receiving water's biota has occurred. Bioassessment sampling guidelines are contained in this General Permit. 66. A summary and evaluation of the sampling and analysis results will be submitted in the Annual Reports. 67.This General Permit contains sampling, analysis and monitoring requirements for non-visible pollutants at all sites subject to this General Permit. 68. Compliance with the General Permit relies upon dischargers to electronically self-report any discharge violations and to comply with any Regional Water Board enforcement actions. 69. This General Permit requires that all dischargers maintain a paper or electronic copy of all required records for three years from the date generated or date submitted, whichever is last. These records must be available at the construction site until construction is completed. For LUPs, these documents may be retained in a crew member's vehicle and made available upon request. K. Active Treatment System (ATS) Requirements 70. Active treatment systems add chemicals to facilitate flocculation, coagulation and filtration of suspended sediment particles. The uncontrolled release of these chemicals to the environment can negatively affect the beneficial uses of receiving waters and/or degrade water quality (e.g., acute and chronic toxicity). Additionally, the batch storage and treatment of storm water through an ATS1 can potentially 2009-0009-DWQ 11 September 02,2009 Order cause physical impacts on receiving waters if storage volume is inadequate or due to sudden releases of the ATS batches and improperly designed outfalls. 71. If designed, operated and maintained properly an ATS can achieve very high removal rates of suspended sediment (measured as turbidity), albeit at sometimes significantly higher costs than traditional erosion/sediment control practices. As a result, this General Permit establishes NELs consistent with the expected level of typical ATS performance. 72. This General Permit requires discharges of storm water associated with construction activity that undergo active treatment to comply with special operational and effluent limitations to ensure that these discharges do not adversely affect the beneficial uses of the receiving waters or cause degradation of their water quality. 73. For ATS discharges, this General Permit establishes technology-based NELs for turbidity. 74.This General Permit establishes a 10 year, 24 hour (expressed in inches of rainfall) Compliance Storm Event exemption from the technology-based numeric effluent limitations for ATS discharges. Exceedances of the ATS turbidity NEL constitutes a violation of this General Permit. L. Post-Construction Requirements 75. This General Permit includes performance standards for post- construction that are consistent with State Water Board Resolution No. 2005-0006. "Resolution Adopting the Concept of Sustainability as a Core Value for State Water Board Programs and Directing Its Incorporation," and 2008-0030. "Requiring Sustainable Water Resources Management." The requirement for all construction sites to match pre-project hydrology will help ensure that the physical and biological integrity of aquatic ecosystems are sustained. This "runoff reduction" approach is analogous in principle to Low Impact Development (LID) and will serve to protect related watersheds and waterbodies from both hydrologic-based and pollution impacts associated with the post-construction landscape. 76. LUP projects are not subject to post-construction requirements due to the nature of their construction to return project sites to pre- construction conditions. 2009-0009-DWQ 12 September 02,2009 Order M. Storm Water Pollution Prevention Plan Requirements 77.This General Permit requires the development of a site-specific SWPPP. The SWPPP must include the information needed to demonstrate compliance with all requirements of this General Permit, and must be kept on the construction site and be available for review. The discharger shall ensure that a QSD develops the SWPPP. 78. To ensure proper site oversight, this General Permit requires a Qualified SWPPP Practitioner to oversee implementation of the BMPs required to comply with this General Permit. N. Regional Water Board Authorities 79. Regional Water Boards are responsible for implementation and enforcement of this General Permit. A general approach to permitting is not always suitable for every construction site and environmental circumstances. Therefore, this General Permit recognizes that Regional Water Boards must have some flexibility and authority to alter, approve, exempt, or rescind permit authority granted under this General Permit in order to protect the beneficial uses of our receiving waters and prevent degradation of water quality. 2009-0009-DWQ 13 September 02,2009 Order IT IS HEREBY ORDERED that all dischargers subject to this General Permit shall comply with the following conditions and requirements (including all conditions and requirements as set forth in Attachments A, B, C, D, E and F)6: II. CONDITIONS FOR PERMIT COVERAGE A. Linear Underground/Overhead Projects (LUPs) 1. Linear Underground/Overhead Projects (LUPs) include, but are not limited to, any conveyance, pipe, or pipeline for the transportation of any gaseous, liquid (including water and wastewater for domestic municipal services), liquescent, or slurry substance; any cable line or wire for the transmission of electrical energy; any cable line or wire for communications (e.g. telephone, telegraph, radio or television messages); and associated ancillary facilities. Construction activities associated with LUPs include, but are not limited to, (a) those activities necessary for the installation of underground and overhead linear facilities (e.g., conduits, substructures, pipelines, towers, poles, cables, wires, connectors, switching, regulating and transforming equipment, and associated ancillary facilities); and include, but are not limited to, (b) underground utility mark-out, potholing, concrete and asphalt cutting and removal, trenching, excavation, boring and drilling, access road and pole/tower pad and cable/wire pull station, substation construction, substructure installation, construction of tower footings and/or foundations, pole and tower installations, pipeline installations, welding, concrete and/ or pavement repair or replacement, and stockpile/borrow locations. 2. The utility company, municipality, or other public or private company or agency that owns or operates the linear underground/overhead project is responsible for obtaining coverage under the General Permit where the construction of pipelines, utility lines, fiber-optic cables, or other linear underground/overhead projects will occur across several properties unless the LUP construction activities are covered under another construction storm water permit. 3. Only LUPs shall comply with the conditions and requirements in Attachment A, A.1 & A.2 of this Order. The balance of this Order is not applicable to LUPs except as indicated in Attachment A. B. Obtaining Permit Coverage Traditional Construction Sites These attachments are part of the General Permit itself and are not separate documents that are capable of being updated independently by the State Water Board. 2009-0009-DWQ 14 September 02,2009 Order 1. The Legally Responsible Person (LRP) (see Special Provisions, Electronic Signature and Certification Requirements, Section IV.1,1) must obtain coverage under this General Permit. 2. To obtain coverage, the LRP must electronically file Permit Registration Documents (PRDs) prior to the commencement of construction activity. Failure to obtain coverage under this General Permit for storm water discharges to waters of the United States is a violation of the CWA and the California Water Code. 3. PRDs shall consist of: a. Notice of Intent (NOI) b. Risk Assessment (Section VIII) c. Site Map d. Storm Water Pollution Prevention Plan (Section XIV) e. Annual Fee f. Signed Certification Statement Any information provided to the Regional Water Board shall comply with the Homeland Security Act and any other federal law that concerns security in the United States; any information that does not comply should not be submitted. Attachment B contains additional PRD information. Dischargers must electronically file the PRDs, and mail the appropriate annual fee to the State Water Board. 4. This permit is effective on July 1, 2010. a. Dischargers Obtaining Coverage On or After July 1, 2010: All dischargers requiring coverage on or after July 1, 2010, shall electronically file their PRDs prior to the commencement of construction activities, and mail the appropriate annual fee no later than seven days prior to the commencement of construction activities. Permit coverage shall not commence until the PRDs and the annual fee are received by the State Water Board, and a WDID number is assigned and sent by SMARTS. b. Dischargers Covered Under 99-08-DWQ and 2003-0007-DWQ: Existing dischargers subject to State Water Board Order No. 99-08- DWQ (existing dischargers) will continue coverage under 99-08- DWQ until July 1, 2010. After July 1, 2010, all NOIs subject to State Water Board Order No. 99-08-DWQ will be terminated. Existing dischargers shall electronically file their PRDs no later than 2009-0009-DWQ 15 September 02,2009 Order July 1, 2010. If an existing discharger's site acreage subject to the annual fee has changed, it shall mail a revised annual fee no less than seven days after receiving the revised annual fee notification, or else lose permit coverage. All existing dischargers shall be exempt from the risk determination requirements in Section VIII of this General Permit until two years after permit adoption. All existing dischargers are therefore subject to Risk Level 1 requirements regardless of their site's sediment and receiving water risks. However, a Regional Board retains the authority to require an existing discharger to comply with the Section VIII risk determination requirements. 5. The discharger is only considered covered by this General Permit upon receipt of a Waste Discharger Identification (WDID) number assigned and sent by the State Water Board Storm water Multi-Application and Report Tracking System (SMARTS). In order to demonstrate compliance with this General Permit, the discharger must obtain a WDID number and must present documentation of a valid WDID upon demand. 6. During the period this permit is subject to review by the U.S. EPA, the prior permit (State Water Board Order No. 99-08-DWQ) remains in effect. Existing dischargers under the prior permit will continue to have coverage under State Water Board Order No. 99-08-DWQ until this General Permit takes effect on July 1, 2010. Dischargers who complete their projects and electronically file an NOT prior to July 1, 2010, are not required to obtain coverage under this General Permit. 7. Small Construction Rainfall Erosivity Waiver EPA's Small Construction Erosivity Waiver applies to sites between one and five acres demonstrating that there are no adverse water quality impacts. Dischargers eligible for a Rainfall Erosivity Waiver based on low erosivity potential shall complete the electronic Notice of Intent (NOI) and Sediment Risk form through the State Water Board's SMARTS system, certifying that the construction activity will take place during a period when the value of the rainfall erosivity factor is less than five. Where the LRP changes or another LRP is added during construction, the new LRP must also submit a waiver certification through the SMARTS system. If a small construction site continues beyond the projected completion date given on the waiver certification, the LRP shall recalculate the rainfall erosivity factor for the new project duration and submit this 2009-0009-DWQ 16 September 02,2009 Order information through the SMARTS system. If the new R factor is below five (5), the discharger shall update through SMARTS all applicable information on the waiver certification and retain a copy of the revised waiver onsite. The LRP shall submit the new waiver certification 30 days prior to the projected completion date listed on the original waiver form to assure exemption from permitting requirements is uninterrupted. If the new R factor is five (5) or above, the LRP shall be required to apply for coverage under this Order. 8. In the case of a public emergency that requires immediate construction activities, a discharger shall submit a brief description of the emergency construction activity within five days of the onset of construction, and then shall submit all PRDs within thirty days. C. Revising Permit Coverage for Change of Acreage or New Ownership 1. The discharger may reduce or increase the total acreage covered under this General Permit when a portion of the site is complete and/or conditions for termination of coverage have been met (See Section II.D Conditions for Termination of Coverage); when ownership of a portion of the site is sold to a different entity; or when new acreage, subject to this General Permit, is added to the site. 2. Within 30 days of a reduction or increase in total disturbed acreage, the discharger shall electronically file revisions to the PRDs that include: a. A revised NOI indicating the new project size; b. A revised site map showing the acreage of the site completed, acreage currently under construction, acreage sold/transferred or added, and acreage currently stabilized in accordance with the Conditions for Termination of Coverage in Section II.D below. c. SWPPP revisions, as appropriate; and d. Certification that any new landowners have been notified of applicable requirements to obtain General Permit coverage. The certification shall include the name, address, telephone number, and e-mail address of the new landowner. e. If the project acreage has increased, dischargers shall mail payment of revised annual fees within 14 days of receiving the revised annual fee notification. 2009-0009-DWQ 17 September 02,2009 Order 3. The discharger shall continue coverage under the General Permit for any parcel that has not achieved "Final Stabilization" as defined in Section II.D. 4. When an LRP owns property with active General Permit coverage, and the LRP sells the property, or a parcel thereof, to another person, that person shall become an LRP with respect to whatever parcel was sold. The existing LRP shall inform the new LRP of the General Permit's requirements. In order for the new LRP to continue the construction activity on its parcel of property, the new LRP, or the new LRP's approved signatory, must submit PRDs in accordance with this General Permit's requirements. D. Conditions for Termination of Coverage 1. Within 90 days of when construction is complete or ownership has been transferred, the discharger shall electronically file a Notice of Termination (NOT), a final site map, and photos through the State Water Boards SMARTS system. Filing a NOT certifies that all General Permit requirements have been met. The Regional Water Board will consider a construction site complete only when all portions of the site have been transferred to a new owner, or all of the following conditions have been met: a. For purposes of "final stabilization," the site will not pose any additional sediment discharge risk than it did prior to the commencement of construction activity; b. There is no potential for construction-related storm water pollutants to be discharged into site runoff; c. Final stabilization has been reached; d. Construction materials and wastes have been disposed of properly; e. Compliance with the Post-Construction Standards in Section XIII of this General Permit has been demonstrated; f. Post-construction storm water management measures have been installed and a long-term maintenance plan7 has been established; and 7 For the purposes of this requirement a long-term maintenance plan will be designed for a minimum of five years, and will describe the procedures to ensure that the post-construction storm water management measures are adequately maintained. 2009-0009-DWQ 18 September 02,2009 Order g. All construction-related equipment, materials and any temporary BMPs no longer needed are removed from the site. 2. The discharger shall certify that final stabilization conditions are satisfied in their NOT. Failure to certify shall result in continuation of permit coverage and annual billing. 3. The NOT must demonstrate through photos, RUSLE or RUSLE2, or results of testing and analysis that the site meets all of the conditions above (Section II.D.1) and the final stabilization condition (Section II.D.La) is attained by one of the following methods: a. "70% final cover method," no computational proof required OR: b. "RUSLE or RUSLE2 method," computational proof required OR: c. "Custom method", the discharger shall demonstrate in some other manner than a or b, above, that the site complies with the "final stabilization" requirement in Section II.D.La. 2009-0009-DWQ 19 September 02,2009 Order DISCHARGE PROHIBITIONS A. Dischargers shall not violate any discharge prohibitions contained in applicable Basin Plans or statewide water quality control plans. Waste discharges to Areas of Special Biological Significance (ASBS) are prohibited by the California Ocean Plan, unless granted an exception issued by the State Water Board. B. All discharges are prohibited except for the storm water and non-storm water discharges specifically authorized by this General Permit or another NPDES permit. C. Authorized non-storm water discharges may include those from de- chlorinated potable water sources such as: fire hydrant flushing, irrigation of vegetative erosion control measures, pipe flushing and testing, water to control dust, uncontaminated ground water from dewatering, and other discharges not subject to a separate general NPDES permit adopted by a Regional Water Board. The discharge of non-storm water is authorized under the following conditions: 1. The discharge does not cause or contribute to a violation of any water quality standard; 2. The discharge does not violate any other provision of this General Permit; 3. The discharge is not prohibited by the applicable Basin Plan; 4. The discharger has included and implemented specific BMPs required by this General Permit to prevent or reduce the contact of the non- storm water discharge with construction materials or equipment. 5. The discharge does not contain toxic constituents in toxic amounts or (other) significant quantities of pollutants; 6. The discharge is monitored and meets the applicable NALs and NELs; and 7. The discharger reports the sampling information in the Annual Report. If any of the above conditions are not satisfied, the discharge is not authorized by this General Permit. The discharger shall notify the Regional Water Board of any anticipated non-storm water discharges not already authorized by this General Permit or another NPDES permit, to determine whether a separate NPDES permit is necessary. 2009-0009-DWQ 20 September 02,2009 Order D. Debris resulting from construction activities are prohibited from being discharged from construction sites. E. When soil contamination is found or suspected and a responsible party is not identified, or the responsible party fails to promptly take the appropriate action, the discharger shall have those soils sampled and tested to ensure proper handling and public safety measures are implemented. The discharger shall notify the appropriate local, State, and federal agency(ies) when contaminated soil is found at a construction site, and will notify the appropriate Regional Water Board. 2009-0009-DWQ 21 September 02,2009 Order IV.SPECIAL PROVISIONS A. Duty to Comply 1. The discharger shall comply with all of the conditions of this General Permit. Any permit noncompliance constitutes a violation of the Clean Water Act (CWA) and the Porter-Cologne Water Quality Control Act and is grounds for enforcement action and/or removal from General Permit coverage. 2. The discharger shall comply with effluent standards or prohibitions established under Section 307(a) of the CWA for toxic pollutants within the time provided in the regulations that establish these standards or prohibitions, even if this General Permit has not yet been modified to incorporate the requirement. B. General Permit Actions 1. This General Permit may be modified, revoked and reissued, or terminated for cause. The filing of a request by the discharger for a General Permit modification, revocation and reissuance, or termination, or a notification of planned changes or anticipated noncompliance does not annul any General Permit condition. 2. If any toxic effluent standard or prohibition (including any schedule of compliance specified in such effluent standard or prohibition) is promulgated under Section 307(a) of the CWA for a toxic pollutant which is present in the discharge and that standard or prohibition is more stringent than any limitation on the pollutant in this General Permit, this General Permit shall be modified or revoked and reissued to conform to the toxic effluent standard or prohibition and the dischargers so notified. C. Need to Halt or Reduce Activity Not a Defense It shall not be a defense for a discharger in an enforcement action that it would have been necessary to halt or reduce the permitted activity in order to maintain compliance with the conditions of this General Permit. D. Duty to Mitigate The discharger shall take all responsible steps to minimize or prevent any discharge in violation of this General Permit, which has a reasonable likelihood of adversely affecting human health or the environment. 2009-0009-DWQ 22 September 02,2009 Order E. Proper Operation and Maintenance The discharger shall at all times properly operate and maintain any facilities and systems of treatment and control (and related appurtenances) which are installed or used by the discharger to achieve compliance with the conditions of this General Permit. Proper operation and maintenance also includes adequate laboratory controls and appropriate quality assurance procedures. Proper operation and maintenance may require the operation of backup or auxiliary facilities or similar systems installed by a discharger when necessary to achieve compliance with the conditions of this General Permit. F. Property Rights This General Permit does not convey any property rights of any sort or any exclusive privileges, nor does it authorize any injury to private property or any invasion of personal rights, nor does it authorize any infringement of Federal, State, or local laws or regulations. G. Duty to Maintain Records and Provide Information 1. The discharger shall maintain a paper or electronic copy of all required records, including a copy of this General Permit, for three years from the date generated or date submitted, whichever is last. These records shall be available at the construction site until construction is completed. 2. The discharger shall furnish the Regional Water Board, State Water Board, or U.S. EPA, within a reasonable time, any requested information to determine compliance with this General Permit. The discharger shall also furnish, upon request, copies of records that are required to be kept by this General Permit. H. Inspection and Entry The discharger shall allow the Regional Water Board, State Water Board, U.S. EPA, and/or, in the case of construction sites which discharge through a municipal separate storm sewer, an authorized representative of the municipal operator of the separate storm sewer system receiving the discharge, upon the presentation of credentials and other documents as may be required by law, to: 1. Enter upon the discharger's premises at reasonable times where a regulated construction activity is being conducted or where records must be kept under the conditions of this General Permit; 2009-0009-DWQ 23 September 02,2009 Order 2. Access and copy at reasonable times any records that must be kept under the conditions of this General Permit; 3. Inspect at reasonable times the complete construction site, including any off-site staging areas or material storage areas, and the erosion/sediment controls; and 4. Sample or monitor at reasonable times for the purpose of ensuring General Permit compliance. I. Electronic Signature and Certification Requirements 1. All Permit Registration Documents (PRDs) and Notice of Terminations (NOTs) shall be electronically signed, certified, and submitted via SMARTS to the State Water Board. Either the Legally Responsible Person (LRP) or a person legally authorized to sign and certify PRDs and NOTs on behalf of the LRP (the LRP's Approved Signatory) must submit all information electronically via SMARTS. a. The LRP's Approved Signatory must be one of the following: i. For a corporation: a responsible corporate officer. For the purpose of this section, a responsible corporate officer means: (a) a president, secretary, treasurer, or vice-president of the corporation in charge of a principal business function, or any other person who performs similar policy or decision-making functions for the corporation; or (b) the manager of the facility if authority to sign documents has been assigned or delegated to the manager in accordance with corporate procedures; ii. For a partnership or sole proprietorship: a general partner or the proprietor, respectively; iii. For a municipality, State, Federal, or other public agency: either a principal executive officer or ranking elected official. The principal executive officer of a Federal agency includes the chief executive officer of the agency or the senior executive officer having responsibility for the overall operations of a principal geographic unit of the agency (e.g., Regional Administrators of U.S. EPA); iv. For the military: Any military officer who has been designated, v. For a public university: An authorized university official 2009-0009-DWQ 24 September 02,2009 Order b. Changes to Authorization. If an approved signatory's authorization is no longer accurate, a new authorization satisfying the requirements of paragraph (a) of this section must be submitted via SMARTS prior to or together with any reports, information or applications to be signed by an approved signatory. 2. All Annual Reports, or other information required by the General Permit (other than PRDs and NOTs) or requested by the Regional Water Board, State Water Board, U.S. EPA, or local storm water management agency shall be certified and submitted by the LRP or the LRP's approved signatory as described above. J. Certification Any person signing documents under Section IV.I above, shall make the following certification: "I certify under penalty of law that this document and all attachments were prepared under my direction or supervision in accordance with a system designed to assure that qualified personnel properly gather and evaluate the information submitted. Based on my inquiry of the person or persons who manage the system or those persons directly responsible for gathering the information, to the best of my knowledge and belief, the information submitted is, true, accurate, and complete. I am aware that there are significant penalties for submitting false information, including the possibility of fine and imprisonment for knowing violations." K. Anticipated Noncompliance The discharger shall give advance notice to the Regional Water Board and local storm water management agency of any planned changes in the construction activity, which may result in noncompliance with General Permit requirements. L. Bypass Bypass8 is prohibited. The Regional Water Board may take enforcement action against the discharger for bypass unless: 1. Bypass was unavoidable to prevent loss of life, personal injury or severe property damage;9 8 The intentional diversion of waste streams from any portion of a treatment facility9 Severe property damage means substantial physical damage to property, damage to the treatment facilities that causes them to become inoperable, or substantial and permanent loss of natural resources that can reasonably be expected to occur in the absence of a bypass. Severe property damage does not mean economic loss caused by delays in production. 2009-0009-DWQ 25 September 02,2009 Order 2. There were no feasible alternatives to bypass, such as the use of auxiliary treatment facilities, retention of untreated waste, or maintenance during normal periods of equipment downtime. This condition is not satisfied if adequate back-up equipment should have been installed in the exercise of reasonable engineering judgment to prevent a bypass that could occur during normal periods of equipment downtime or preventative maintenance; 3. The discharger submitted a notice at least ten days in advance of the need for a bypass to the Regional Water Board; or 4. The discharger may allow a bypass to occur that does not cause effluent limitations to be exceeded, but only if it is for essential maintenance to assure efficient operation. In such a case, the above bypass conditions are not applicable. The discharger shall submit notice of an unanticipated bypass as required. M. Upset 1. A discharger that wishes to establish the affirmative defense of an upset10 in an action brought for noncompliance shall demonstrate, through properly signed, contemporaneous operating logs, or other relevant evidence that: a. An upset occurred and that the discharger can identify the cause(s) of the upset b. The treatment facility was being properly operated by the time of the upset c. The discharger submitted notice of the upset as required; and d. The discharger complied with any remedial measures required 2. No determination made before an action of noncompliance occurs, such as during administrative review of claims that noncompliance was caused by an upset, is final administrative action subject to judicial review. 3. In any enforcement proceeding, the discharger seeking to establish the occurrence of an upset has the burden of proof 10 An exceptional incident in which there is unintentional and temporary noncompliance the technology based numeric effluent limitations because of factors beyond the reasonable control of the discharger. An upset does not include noncompliance to the extent caused by operational error, improperly designed treatment facilities, inadequate treatment facilities, lack of preventative maintenance, or careless or improper operation. 2009-0009-DWQ 26 September 02,2009 Order N. Penalties for Falsification of Reports Section 309(c)(4) of the CWA provides that any person who knowingly makes any false material statement, representation, or certification in any record or other document submitted or required to be maintained under this General Permit, including reports of compliance or noncompliance shall upon conviction, be punished by a fine of not more than $10,000 or by imprisonment for not more than two years or by both. O. Oil and Hazardous Substance Liability Nothing in this General Permit shall be construed to preclude the institution of any legal action or relieve the discharger from any responsibilities, liabilities, or penalties to which the discharger is or may be subject to under Section 311 of the CWA. P. Severability The provisions of this General Permit are severable; and, if any provision of this General Permit or the application of any provision of this General Permit to any circumstance is held invalid, the application of such provision to other circumstances and the remainder of this General Permit shall not be affected thereby. Q. Reopener Clause This General Permit may be modified, revoked and reissued, or terminated for cause due to promulgation of amended regulations, receipt of U.S. EPA guidance concerning regulated activities, judicial decision, or in accordance with 40 Code of Federal Regulations (CFR) 122.62, 122.63, 122.64, and 124.5. R. Penalties for Violations of Permit Conditions 1. Section 309 of the CWA provides significant penalties for any person who violates a permit condition implementing Sections 301, 302, 306, 307, 308, 318, or 405 of the CWA or any permit condition or limitation implementing any such section in a permit issued under Section 402. Any person who violates any permit condition of this General Permit is subject to a civil penalty not to exceed $37,50011 per calendar day of such violation, as well as any other appropriate sanction provided by Section 309 of the CWA. 11 May be further adjusted in accordance with the Federal Civil Penalties Inflation Adjustment Act. 2009-0009-DWQ 27 September 02,2009 Order 2. The Porter-Cologne Water Quality Control Act also provides for civil and criminal penalties, which in some cases are greater than those under the CWA. S. Transfers This General Permit is not transferable. T. Continuation of Expired Permit This General Permit continues in force and effect until a new General Permit is issued or the SWRCB rescinds this General Permit. Only those dischargers authorized to discharge under the expiring General Permit are covered by the continued General Permit. 2009-0009-DWQ 28 September 02,2009 Order V. EFFLUENT STANDARDS A.

The numerical value of R is the average annual sum of EI30 for storm events during a rainfall record of at least 22 years. "Isoerodent" maps were developed based on R values calculated for more than 1000 locations in the Western U.S. Refer to the link below to determine the R factor for the project site. httD://cfpub.epa.gov/npdes/stormwater/LEW/lewCalculator.cfm R Factor Valu 7.86 B) K Factor (weighted average, by area, for all site soils) The soil-erodibility factor K represents: (1) susceptibility of soil or surface material to erosion, (2) transportability of the sediment, and (3) the amount and rate of runoff given a particular rainfall input, as measured under a standard condition. Fine-textured soils that are high in clay have low K values (about 0.05 to 0.15) because the particles are resistant to detachment. Coarse-textured soils, such as sandy soils, also have low K values (about 0.05 to 0.2) because of high infiltration resulting in low runoff even though these particles are easily detached. Medium-textured soils, such as a silt loam, have moderate K values (about 0.25 to 0.45) because they are moderately susceptible to particle detachment and they produce runoff at moderate rates. Soils having a high silt content are especially susceptible to erosion and have high K values, which can exceed 0.45 and can be as large as 0.65. Silt-size particles are easily detached and tend to crust, producing high rates and large volumes of runoff. Use Site-specific data must be submitted. Site-specific K factor guidance K Factor Value 0.28 10 C) LS Factor (weighted average, by area, for all slopes) 11 The effect of topography on erosion is accounted for by the LS factor, which combines the effects of a hillslope-length factor, L, and a hillslope-gradient factor, S. Generally speaking, as hillslope length and/or hillslope gradient increase, soil loss increases. As hillslope length increases, total soil loss and soil loss per unit area increase due to the progressive accumulation of runoff in the downslope direction. As the hillslope gradient increases, the velocity and erosivity of runoff increases. Use the LS table located in separate tab of this spreadsheet to determine LS factors. Estimate the weighted LS for the site prior to construction. 12 LS Table 13 LS Factor Value 0.2 15 Watershed Erosion Estimate (=RxKxLS) in tons/acre 0.44016 16 17 18 19 20 Site Sediment Risk Factor Low Sediment Risk: < 15 tons/acre Medium Sediment Risk: >=15 and <75 tons/acre Low High Sediment Risk: >= 75 tons/acre EPA NPDES - Well-'me to the Lower Erosivity Index Calculator U.S. ENVIRONMENTAL PROTECTION AGENCY Basic Information Municipal MS4s Construction Activities Industrial Activities Road-Related MS4s Menu of BMPs Green Infrastructure Urban BMP Tool Stormwater Home National Pollutant Discharge Elimination System (NPDES) Recent Additions | Contact Us | Print Version Search NPDES: [_ EPA Home > OW Home > OWM Home > NPDES Home > Alphabetical Index Glossary About NPDES Rainfall Erosivity Factor Calculator for Small Construction Sites Facility Information Facility Name: Calavera Hills Sewer Facility Demolition Start Date: 04/01/2011 End Date: 10/01/2011 Address: Tamarack Avenue at Edinburgh Road, Carlsbad, California 92008 Latitude: 33.1635419 Longitutde: -117.3010187 Erosivity Index Calculator Results AN EROSIVITY INDEX VALUE OF 7.86 HAS BEEN DETERMINED FOR THE CONSTRUCTION PERIOD OF 04/01/2011 - 10/01/2011 A rainfall erosivity factor of 5.0 or greater has been calculated for your site and period of construction.

Factor K is one of six factors used in the Universal Soil Loss Equation (USLE) and the Revised Universal Soil Loss Equation (RUSLE) to predict the average annual rate of soil loss by sheet and rill erosion in tons per acre per year. The estimates are based primarily on percentage of silt, sand, and organic matter and on soil structure and saturated hydraulic conductivity (Ksat). Values of K range from 0.02 to 0.69. Other factors being equal, the higher the value, the more susceptible the soil is to sheet and rill erosion by water. "Erosion factor Kw (whole soil)" indicates the erodibility of the whole soil. The estimates are modified by the presence of rock fragments.

The purpose is to reduce the amount and duration of soil exposed to erosion by wind, rain, runoff, and vehicle tracking, and to perform the construction activities and control practices in accordance with the planned schedule. Suitable Applications Proper sequencing of construction activities to reduce erosion potential should be incorporated into the schedule of every construction project especially during rainy season. Use of other, more costly yet less effective, erosion and sediment control BMPs may often be reduced through proper construction sequencing. Limitations • Environmental constraints such as nesting season prohibitions reduce the full capabilities of this BMP. Implementation • Avoid rainy periods. Schedule major grading operations during dry months when practical. Allow enough time before rainfall begins to stabilize the soil with vegetation or physical means or to install sediment trapping devices. • Plan the project and develop a schedule showing each phase Categories EC SE TC WE NS WM Erosion Control Sediment Control Tracking Control Wind Erosion Control Non-Stormwater Management Control Waste Management and Materials Pollution Control 0m m m Legend: El Primary Objective H Secondary Objective Targeted Constituents Sediment [ Nutrients Trash Metals Bacteria Oil and Grease Organics Potential Alternatives None CAUraHNlASTORMWATJ-R Q!,'.M U'V ^-iMK.'i ATti'S' November 2009 California Stormwater BMP Handbook Construction www.casqa.org Iof3 Scheduling EC-1 of construction.

Incorporate the construction schedule into the SWPPP. • Include on the schedule, details on the rainy season implementation and deployment of: Erosion control BMPs Sediment control BMPs Tracking control BMPs Wind erosion control BMPs Non-stormwater BMPs Waste management and materials pollution control BMPs • Include dates for activities that may require non-stormwater discharges such as dewatering, sawcutting, grinding, drilling, boring, crushing, blasting, painting, hydro-demolition, mortar mixing, pavement cleaning, etc. • Work out the sequencing and timetable for the start and completion of each item such as site clearing and grubbing, grading, excavation, paving, foundation pouring utilities installation, etc., to minimize the active construction area during the rainy season. Sequence trenching activities so that most open portions are closed before new trenching begins. Incorporate staged seeding and re-vegetation of graded slopes as work progresses. Schedule establishment of permanent vegetation during appropriate planting time for specified vegetation. • Non-active areas should be stabilized as soon as practical after the cessation of soil disturbing activities or one day prior to the onset of precipitation. • Monitor the weather forecast for rainfall. • When rainfall is predicted, adjust the construction schedule to allow the implementation of soil stabilization and sediment treatment controls on all disturbed areas prior to the onset of rain. • Be prepared year round to deploy erosion control and sediment control BMPs. Erosion may be caused during dry seasons by un-seasonal rainfall, wind, and vehicle tracking. Keep the site stabilized year round, and retain and maintain rainy season sediment trapping devices in operational condition. • Apply permanent erosion control to areas deemed substantially complete during the project's defined seeding window. Costs Construction scheduling to reduce erosion may increase other construction costs due to reduced economies of scale in performing site grading. The cost effectiveness of scheduling techniques should be compared with the other less effective erosion and sedimentation controls to achieve a cost effective balance. November 2009 California Stormwater BMP Handbook 2 of 3 Construction www.casqa.org Scheduling EC-1 Inspection and Maintenance • Verify that work is progressing in accordance with the schedule. If progress deviates, take corrective actions. • Amend the schedule when changes are warranted. • Amend the schedule prior to the rainy season to show updated information on the deployment and implementation of construction site BMPs.

November 2009 California Stormwater BMP Handbook 3 of 3 Construction www.casqa.org Preservation Of Existing Vegetation EC-2 Description and Purpose Carefully planned preservation of existing vegetation minimizes the potential of removing or injuring existing trees, vines, shrubs, and grasses that protect soil from erosion. Suitable Applications Preservation of existing vegetation is suitable for use on most projects. Large project sites often provide the greatest opportunity for use of this BMP. Suitable applications include the following: • Areas within the site where no construction activity occurs, or occurs at a later date. This BMP is especially suitable to multi year projects where grading can be phased. • Areas where natural vegetation exists and is designated for preservation. Such areas often include steep slopes, watercourse, and building sites in wooded areas. • Areas where local, state, and federal government require preservation, such as vernal pools, wetlands, marshes, certain oak trees, etc. These areas are usually designated on the plans, or in the specifications, permits, or environmental documents. » Where vegetation designated for ultimate removal can be temporarily preserved and be utilized for erosion control and sediment control.

Implementation The best way to prevent erosion is to not disturb the land. In order to reduce the impacts of new development and redevelopment, projects may be designed to avoid disturbing land in sensitive areas of the site (e.g., natural watercourses, steep slopes), and to incorporate unique or desirable existing vegetation into the site's landscaping plan. Clearly marking and leaving a buffer area around these unique areas during construction will help to preserve these areas as well as take advantage of natural erosion prevention and sediment trapping. Existing vegetation to be preserved on the site must be protected from mechanical and other injury while the land is being developed. The purpose of protecting existing vegetation is to ensure the survival of desirable vegetation for shade, beautification, and erosion control. Mature vegetation has extensive root systems that help to hold soil in place, thus reducing erosion. In addition, vegetation helps keep soil from drying rapidly and becoming susceptible to erosion. To effectively save existing vegetation, no disturbances of any kind should be allowed within a defined area around the vegetation. For trees, no construction activity should occur within the drip line of the tree. Timing • Provide for preservation of existing vegetation prior to the commencement of clearing and grubbing operations or other soil disturbing activities in areas where no construction activity is planned or will occur at a later date. Design and Layout m Mark areas to be preserved with temporary fencing. Include sufficient setback to protect roots. - Orange colored plastic mesh fencing works well. - Use appropriate fence posts and adequate post spacing and depth to completely support the fence in an upright position. • Locate temporary roadways, stockpiles, and layout areas to avoid stands of trees, shrubs, and grass. • Consider the impact of grade changes to existing vegetation and the root zone. • Maintain existing irrigation systems where feasible. Temporary irrigation may be required. • Instruct employees and subcontractors to honor protective devices. Prohibit heavy equipment, vehicular traffic, or storage of construction materials within the protected area. November 2009 California Stormwater BMP Handbook 2 of 4 Construction www.casqa.org Preservation Of Existing Vegetation EC-2 Costs There is little cost associated with preserving existing vegetation if properly planned during the project design, and these costs may be offset by aesthetic benefits that enhance property values. During construction, the cost for preserving existing vegetation will likely be less than the cost of applying erosion and sediment controls to the disturbed area. Replacing vegetation inadvertently destroyed during construction can be extremely expensive, sometimes in excess of $10,000 per tree. Inspection and Maintenance During construction, the limits of disturbance should remain clearly marked at all times. Irrigation or maintenance of existing vegetation should be described in the landscaping plan. If damage to protected trees still occurs, maintenance guidelines described below should be followed: • Verify that protective measures remain in place. Restore damaged protection measures immediately. • Serious tree injuries shall be attended to by an arborist. • Damage to the crown, trunk, or root system of a retained tree shall be repaired immediately. • Trench as far from tree trunks as possible, usually outside of the tree drip line or canopy. Curve trenches around trees to avoid large roots or root concentrations. If roots are encountered, consider tunneling under them. When trenching or tunneling near or under trees to be retained, place tunnels at least 18 in. below the ground surface, and not below the tree center to minimize impact on the roots. • Do not leave tree roots exposed to air. Cover exposed roots with soil as soon as possible. If soil covering is not practical, protect exposed roots with wet burlap or peat moss until the tunnel or trench is ready for backfill. • Cleanly remove the ends of damaged roots with a smooth cut. • Fill trenches and tunnels as soon as possible. Careful filling and tamping will eliminate air spaces in the soil, which can damage roots. • If bark damage occurs, cut back all loosened bark into the undamaged area, with the cut tapered at the top and bottom and drainage provided at the base of the wood. Limit cutting the undamaged area as much as possible. • Aerate soil that has been compacted over a trees root zone by punching holes 12 in. deep with an iron bar, and moving the bar back and forth until the soil is loosened. Place holes 18 in. apart throughout the area of compacted soil under the tree crown. • Fertilization - Fertilize stressed or damaged broadleaf trees to aid recovery. - Fertilize trees in the late fall or early spring. November 2009 California Stormwater BMP Handbook 3 of 4 Construction www.casqa.org Preservation Of Existing Vegetation EC-2 Apply fertilizer to the soil over the feeder roots and in accordance with label instructions, but never closer than 3 ft to the trunk. Increase the fertilized area by one-fourth of the crown area for conifers that have extended root systems. • Retain protective measures until all other construction activity is complete to avoid damage during site cleanup and stabilization.

November 2009 California Stormwater BMP Handbook 4 of 4 Construction www.casqa.org Hydroseeding EC-4 Description and Purpose Hydroseeding typically consists of applying a mixture of a hydraulic mulch, seed, fertilizer, and stabilizing emulsion with a hydraulic mulcher, to temporarily protect exposed soils from erosion by water and wind. Hydraulic seeding, or hydroseeding, is simply the method by which temporary or permanent seed is applied to the soil surface. Suitable Applications Hydroseeding is suitable for disturbed areas requiring temporary protection until permanent stabilization is established, for disturbed areas that will be re-disturbed following an extended period of inactivity, or to apply permanent stabilization measures. Hydroseeding without mulch or other cover (e.g. EC-7, Erosion Control Blanket) is not a stand-alone erosion control BMP and should be combined with additional measures until vegetation establishment. Typical applications for hydroseeding include: • Disturbed soil/graded areas where permanent stabilization or continued earthwork is not anticipated prior to seed germination. • Cleared and graded areas exposed to seasonal rains or temporary irrigation. • Areas not subject to heavy wear by construction equipment or high traffic.

Implementation In order to select appropriate hydraulic seed mixtures, an evaluation of site conditions should be performed with respect to: Soil conditions - Maintenance requirements Site topography and exposure (sun/wind) - Sensitive adjacent areas Season and climate - Water availability Vegetation types - Plans for permanent vegetation The local office of the U.S.D.A. Natural Resources Conservation Service (NRCS) is an excellent source of information on appropriate seed mixes. The following steps should be followed for implementation: • Where appropriate or feasible, soil should be prepared to receive the seed by disking or otherwise scarifying (See EC-is, Soil Preparation) the surface to eliminate crust, improve air and water infiltration and create a more favorable environment for germination and growth. November 2009 California Stormwater BMP Handbook 2 of 4 Construction www.casqa.org Hydroseeding EC-4 • Avoid use of hydraulic seed in areas where the BMP would be incompatible with future earthwork activities. • Hydraulic seed can be applied using a multiple step or one step process. - In a multiple step process, hydraulic seed is applied first, followed by mulch or a Rolled Erosion Control Product (RECP). In the one step process, hydraulic seed is applied with hydraulic mulch in a hydraulic matrix. When the one step process is used to apply the mixture of fiber, seed, etc., the seed rate should be increased to compensate for all seeds not having direct contact with the soil. • All hydraulically seeded areas should have mulch, or alternate erosion control cover to keep seeds in place and to moderate soil moisture and temperature until the seeds germinate and grow. • All seeds should be in conformance with the California State Seed Law of the Department of Agriculture. Each seed bag should be delivered to the site sealed and clearly marked as to species, purity, percent germination, dealer's guarantee, and dates of test. The container should be labeled to clearly reflect the amount of Pure Live Seed (PLS) contained. All legume seed should be pellet inoculated. Inoculant sources should be species specific and should be applied at a rate of 2 Ib of inoculant per 100 Ib seed. • Commercial fertilizer should conform to the requirements of the California Food and Agricultural Code, which can be found at http://www.leginfo.ca.gov/.html/fac_table_of_contents.html. Fertilizer should be pelleted or granular form. • Follow up applications should be made as needed to cover areas of poor coverage or germination/vegetation establishment and to maintain adequate soil protection. • Avoid over spray onto roads, sidewalks, drainage channels, existing vegetation, etc. • Additional guidance on the comparison and selection of temporary slope stabilization methods is provided in Appendix F of the Handbook. Costs Average cost for installation and maintenance may vary from as low as $1,900 per acre for flat slopes and stable soils, to $4,000 per acre for moderate to steep slopes and/or erosive soils. Cost of seed mixtures vary based on types of required vegetation.

It is recommended that at a minimum, BMPs be inspected weekly, prior to forecasted rain events, daily during extended rain events, and after the conclusion of rain events. • Areas where erosion is evident should be repaired and BMPs re-applied as soon as possible. Care should be exercised to minimize the damage to protected areas while making repairs, as any area damaged will require re-application of BMPs. • Where seeds fail to germinate, or they germinate and die, the area must be re-seeded, fertilized, and mulched within the planting season, using not less than half the original application rates. • Irrigation systems, if applicable, should be inspected daily while in use to identify system malfunctions and line breaks. When line breaks are detected, the system must be shut down immediately and breaks repaired before the system is put back into operation. • Irrigation systems should be inspected for complete coverage and adjusted as needed to maintain complete coverage.

November 2009 California Stormwater BMP Handbook 4 of 4 Construction www.casqa.org Soil Binders EC-5 Categories Description and Purpose Soil binding consists of application and maintenance of a soil stabilizer to exposed soil surfaces. Soil binders are materials applied to the soil surface to temporarily prevent water and wind induced erosion of exposed soils on construction sites. Suitable Applications Soil binders are typically applied to disturbed areas requiring temporary protection. Because soil binders, when used as a stand-alone practice, can often be incorporated into the soil, they are a good alternative to mulches in areas where grading activities will soon resume. Soil binders are commonly used in the following areas: • Rough graded soils that will be inactive for a short period of time • Soil stockpiles • Temporary haul roads prior to placement of crushed rock • Compacted soil road base • Construction staging, materials storage, and layout areas Limitations • Soil binders are temporary in nature and may need reapplication.

Curing time maybe 24 hours or longer. Soil binders may need reapplication after a storm event. • Soil binders will generally experience spot failures during heavy rainfall events. If runoff penetrates the soil at the top of a slope treated with a soil binder, it is likely that the runoff will undercut the stabilized soil layer and discharge at a point further down slope. • Plant-material-based soil binders do not generally hold up to pedestrian or vehicular traffic across treated areas as well as polymeric emulsion blends or cementitious-based binders. • Soil binders may not sufficiently penetrate compacted soils. • Some soil binders are soil texture specific in terms of their effectiveness. For example, polyacrylamides (PAMs) work very well on silt and clayey soils but their performance decreases dramatically in sandy soils. • Some soil binders may not perform well with low relative humidity. Under rainy conditions, some agents may become slippery or leach out of the soil. • Soil binders may not cure if low temperatures occur within 24 hours of application. • The water quality impacts of some chemical soil binders are relatively unknown and some may have water quality impacts due to their chemical makeup. Implementation General Considerations • Soil binders should conform to local municipality specifications and requirements. • Site soil types will dictate appropriate soil binders to be used. » A soil binder must be environmentally benign (non-toxic to plant and animal life), easy to apply, easy to maintain, economical, and should not stain paved or painted surfaces. Soil binders should not pollute stormwater when cured. Obtain a Material Safety Data Sheet (MSDS) from the manufacturer to ensure non-toxicity. • Stormwater runoff from PAM treated soils should pass through one of the following sediment control BMP prior to discharging to surface waters. When the total drainage area is greater than or equal to 5 acres, PAM treated areas should drain to a sediment basin. Areas less than 5 acres should drain to sediment control BMPs, such as a sediment trap, or a series of check dams. The total number of check dams used should be maximized to achieve the greatest amount of settlement of sediment prior to discharging from the site. Each check dam should be spaced evenly in the drainage channel through which stormwater flows are discharged off site. • Performance of soil binders depends on temperature, humidity, and traffic across treated areas. November 2009 California Stormwater BMP Handbook 2 of 8 Construction www.casqa.org Soil Binders EC-5 • Avoid over spray onto roads, sidewalks, drainage channels, existing vegetation, etc. • Additional guidance on the comparison and selection of temporary slope stabilization methods is provided in Appendix F of the Handbook. Selecting a Soil Binder Properties of common soil binders used for erosion control are provided on Table i at the end of this Fact Sheet. Use Table i to select an appropriate soil binder. Refer to WE-i, Wind Erosion Control, for dust control soil binders. Factors to consider when selecting a soil binder include the following: • Suitability to situation - Consider where the soil binder will be applied, if it needs a high resistance to leaching or abrasion, and whether it needs to be compatible with any existing vegetation. Determine the length of time soil stabilization will be needed, and if the soil binder will be placed in an area where it will degrade rapidly. In general, slope steepness is not a discriminating factor for the listed soil binders. • Soil types and surface materials - Fines and moisture content are key properties of surface materials. Consider a soil binder's ability to penetrate, likelihood of leaching, and ability to form a surface crust on the surface materials. • Frequency of application - The frequency of application is related to the functional longevity of the binder, which can be affected by subgrade conditions, surface type, climate, and maintenance schedule. • Frequent applications could lead to high costs. Application frequency may be minimized if the soil binder has good penetration, low evaporation, and good longevity. Consider also that frequent application will require frequent equipment clean up. Plant-Material-Based (Short Lived, <6 months) Binders Guar: Guar is a non-toxic, biodegradable, natural galactomannan-based hydrocolloid treated with dispersant agents for easy field mixing. It should be mixed with water at the rate of 11 to 15 Ib per 1,000 gallons. Recommended minimum application rates are as follows: Application Rates for Guar Soil Stabilizer Slope (H:V): Ib/acre: Flat 40 4:1 45 3:i 50 2:1 60 1:1 70 Psvllium: Psyllium is composed of the finely ground muciloid coating of plantago seeds that is applied as a dry powder or in a wet slurry to the surface of the soil. It dries to form a firm but rewettable membrane that binds soil particles together, but permits germination and growth of seed. Psyllium requires 12 to 18 hours drying time. Application rates should be from 80 to 200 Ib/acre, with enough water in solution to allow for a uniform slurry flow. Starch: Starch is non-ionic, cold water soluble (pre-gelatinized) granular cornstarch. The material is mixed with water and applied at the rate of 150 Ib/acre. Approximate drying time is 9 to 12 hours. November 2009 California Stormwater BMP Handbook 3 of 8 Construction www.casqa.org Soil Binders EC-5 Plant-Material-Based (Long Lived, 6-12 months) Binders Pitch and Rosin Emulsion: Generally, a non-ionic pitch and rosin emulsion has a minimum solids content of 48%. The rosin should be a minimum of 26% of the total solids content. The soil stabilizer should be non-corrosive, water dilutable emulsion that upon application cures to a water insoluble binding and cementing agent. For soil erosion control applications, the emulsion is diluted and should be applied as follows: • For clayey soil: 5 parts water to i part emulsion • For sandy soil: 10 parts water to i part emulsion Application can be by water truck or hydraulic seeder with the emulsion and product mixture applied at the rate specified by the manufacturer. Polymeric Emulsion Blend Binders Acrylic Copolvmers and Polymers: Polymeric soil stabilizers should consist of a liquid or solid polymer or copolymer with an acrylic base that contains a minimum of 55% solids. The polymeric compound should be handled and mixed in a manner that will not cause foaming or should contain an anti-foaming agent. The polymeric emulsion should not exceed its shelf life or expiration date; manufacturers should provide the expiration date. Polymeric soil stabilizer should be readily miscible in water, non-injurious to seed or animal life, non-flammable, should provide surface soil stabilization for various soil types without totally inhibiting water infiltration, and should not re-emulsify when cured. The applied compound typically requires 12 to 24 hours drying time. Liquid copolymer should be diluted at a rate of 10 parts water to i part polymer and the mixture applied to soil at a rate of 1,175 gallons/acre. Liquid Polymers of Methacrvlates and Acrvlates: This material consists of a tacWfier/sealer that is a liquid polymer of methacrylates and acrylates. It is an aqueous 100% acrylic emulsion blend of 40% solids by volume that is free from styrene, acetate, vinyl, ethoxylated surfactants or silicates. For soil stabilization applications, it is diluted with water in accordance with the manufacturer's recommendations, and applied with a hydraulic seeder at the rate of 20 gallons/acre. Drying time is 12 to 18 hours after application. Copolvmers of Sodium Acrylates and Acrylamides: These materials are non-toxic, dry powders that are copolvmers of sodium acrylate and acrylamide. They are mixed with water and applied to the soil surface for erosion control at rates that are determined by slope gradient: Slope Gradient (H:V) Flat to 5:1 5:1103:1 2:1 to 1:1 Ib/acre 3-0-5-0 5.0 - 10.0 1O.O - 2O.O Poly-Acrylamide TPAM) and Copolymer of Acrylamide; Linear copolymer polyacrylamide for use as a soil binder is packaged as a dry flowable solid, as a liquid. Refer to the manufacturer's recommendation for dilution and application rates as they vary based on liquid or dry form, site conditions and climate. • Limitations specific to PAM are as follows: November 2009 California Stormwater BMP Handbook Construction www.casqa.org 4 of 8 Soil Binders EC-5 Do not use PAM on a slope that flows into a water body without passing through a sediment trap or sediment basin. - The specific PAM copolymer formulation must be anionic. Cationic PAM should not be used in any application because of known aquatic toxicity problems. Only the highest drinking water grade PAM, certified for compliance with ANSI/NSF Standard 60 for drinking water treatment, should be used for soil applications. PAM designated for erosion and sediment control should be "water soluble" or "linear" or "non-cross linked". PAM should not be used as a stand-alone BMP to protect against water-based erosion. When combined with mulch, its effectiveness increases dramatically. Hydro-Colloid Polymers: Hydro-Colloid Polymers are various combinations of dry flowable poly-acrylamides, copolymers and hydro-colloid polymers that are mixed with water and applied to the soil surface at rates of 55 to 60 Ib/acre. Drying times are o to 4 hours. Cementitious-Based Binders Gypsum: This is a formulated gypsum based product that readily mixes with water and mulch to form a thin protective crust on the soil surface. It is composed of high purity gypsum that is ground, calcined and processed into calcium sulfate hemihydrate with a minimum purity of 86%. It is mixed in a hydraulic seeder and applied at rates 4,000 to 12,000 Ib/acre. Drying time is 4 to 8 hours. Applying Soil Binders After selecting an appropriate soil binder, the untreated soil surface must be prepared before applying the soil binder. The untreated soil surface must contain sufficient moisture to assist the agent in achieving uniform distribution. In general, the following steps should be followed: • Follow manufacturer's written recommendations for application rates, pre-wetting of application area, and cleaning of equipment after use. • Prior to application, roughen embankment and fill areas. • Consider the drying time for the selected soil binder and apply with sufficient time before anticipated rainfall. Soil binders should not be applied during or immediately before rainfall. • Avoid over spray onto roads, sidewalks, drainage channels, sound walls, existing vegetation, etc. • Soil binders should not be applied to frozen soil, areas with standing water, under freezing or rainy conditions, or when the temperature is below 4O°F during the curing period. • More than one treatment is often necessary, although the second treatment may be diluted or have a lower application rate. • Generally, soil binders require a minimum curing time of 24 hours before they are fully effective. Refer to manufacturer's instructions for specific cure time. November 2009 California Stormwater BMP Handbook 5 of 8 Construction www.casqa.org Soil Binders EC-5 • For liquid agents: Crown or slope ground to avoid ponding. Uniformly pre-wet ground at 0.03 to 0.3 gal/yd2 or according to manufacturer's recommendations. - Apply solution under pressure. Overlap solution 6 to 12 in. - Allow treated area to cure for the time recommended by the manufacturer; typically at least 24 hours. - Apply second treatment before first treatment becomes ineffective, using 50% application rate. In low humidities, reactivate chemicals by re-wetting with water at o.i to 0.2 gal/yd2. Costs Costs vary according to the soil stabilizer selected for implementation.

Note: Expected cost increase is offset by competitive economic conditions. Inspection and Maintenance • BMPs must be inspected in accordance with General Permit requirements for the associated project type and risk level. It is recommended that at a minimum, BMPs be inspected weekly, prior to forecasted rain events, daily during extended rain events, and after the conclusion of rain events. • Areas where erosion is evident should be repaired and BMPs re-applied as soon as possible. Care should be exercised to minimize the damage to protected areas while making repairs, as any area damaged will require re-application of BMPs. • Reapply the selected soil binder as needed to maintain effectiveness.

November 2009 California Stormwater BMP Handbook 8 of 8 Construction www.casqa.org Earth Dikes and Drainage Swales EC-9 Description and Purpose An earth dike is a temporary berm or ridge of compacted soil used to divert runoff or channel water to a desired location. A drainage swale is a shaped and sloped depression in the soil surface used to convey runoff to a desired location. Earth dikes and drainage swales are used to divert off site runoff around the construction site, divert runoff from stabilized areas and disturbed areas, and direct runoff into sediment basins or traps. Suitable Applications Earth dikes and drainage swales are suitable for use, individually or together, where runoff needs to be diverted from one area and conveyed to another. • Earth dikes and drainage swales may be used: To convey surface runoff down sloping land To intercept and divert runoff to avoid sheet flow over sloped surfaces To divert and direct runoff towards a stabilized watercourse, drainage pipe or channel To intercept runoff from paved surfaces Below steep grades where runoff begins to concentrate Along roadways and facility improvements subject to flood drainage Categories EC Erosion Control SE Sediment Control TC Tracking Control WE Wind Erosion Control Non-StormwaterNSManagement Control ......

For larger areas more permanent drainage structures should be built. All drainage structures should be built in compliance with local municipal requirements. • Earth dikes may create more disturbed area on site and become barriers to construction equipment. • Earth dikes must be stabilized immediately, which adds cost and maintenance concerns. • Diverted stormwater may cause downstream flood damage. • Dikes should not be constructed of soils that may be easily eroded. • Regrading the site to remove the dike may add additional cost. • Temporary drains and swales or any other diversion of runoff should not adversely impact upstream or downstream properties. • Temporary drains and swales must conform to local floodplain management requirements. » Earth dikes/drainage swales are not suitable as sediment trapping devices. • It may be necessary to use other soil stabilization and sediment controls such as check dams, plastics, and blankets, to prevent scour and erosion in newly graded dikes, swales, and ditches. • Sediment accumulation, scour depressions, and/or persistent non-stormwater discharges can result in areas of standing water suitable for mosquito production in drainage swales. Implementation The temporary earth dike is a berm or ridge of compacted soil, located in such a manner as to divert stormwater to a sediment trapping device or a stabilized outlet, thereby reducing the potential for erosion and offsite sedimentation. Earth dikes can also be used to divert runoff from offsite and from undisturbed areas away from disturbed areas and to divert sheet flows away from unprotected slopes. An earth dike does not itself control erosion or remove sediment from runoff. A dike prevents erosion by directing runoff to an erosion control device such as a sediment trap or directing runoff away from an erodible area. Temporary diversion dikes should not adversely impact adjacent properties and must conform to local floodplain management regulations, and should not be used in areas with slopes steeper than 10%. Slopes that are formed during cut and fill operations should be protected from erosion by runoff. A combination of a temporary drainage swale and an earth dike at the top of a slope can divert November 2009 California Stormwater BMP Handbook 2 of 7 Construction www.casqa.org Earth Dikes and Drainage Swales EC-9 runoff to a location where it can be brought to the bottom of the slope (see EC-n, Slope Drains). A combination dike and swale is easily constructed by a single pass of a bulldozer or grader and compacted by a second pass of the tracks or wheels over the ridge. Diversion structures should be installed when the site is initially graded and remain in place until post construction BMPs are installed and the slopes are stabilized. Diversion practices concentrate surface runoff, increasing its velocity and erosive force. Thus, the flow out of the drain or swale must be directed onto a stabilized area or into a grade stabilization structure. If significant erosion will occur, a swale should be stabilized using vegetation, chemical treatment, rock rip-rap, matting, or other physical means of stabilization. Any drain or swale that conveys sediment laden runoff must be diverted into a sediment basin or trap before it is discharged from the site. General m Care must be applied to correctly size and locate earth dikes, drainage swales. Excessively steep, unlined dikes, and swales are subject to erosion and gully formation. • Conveyances should be stabilized. • Use a lined ditch for high flow velocities. • Select flow velocity based on careful evaluation of the risks due to erosion of the measure, soil types, overtopping, flow backups, washout, and drainage flow patterns for each project site. • Compact any fills to prevent unequal settlement. • Do not divert runoff onto other property without securing written authorization from the property owner. • When possible, install and utilize permanent dikes, swales, and ditches early in the construction process. • Provide stabilized outlets. Earth Dikes Temporary earth dikes are a practical, inexpensive BMP used to divert stormwater runoff. Temporary diversion dikes should be installed in the following manner: • All dikes should be compacted by earth moving equipment. • All dikes should have positive drainage to an outlet. • All dikes should have 2:1 or flatter side slopes, 18 in. minimum height, and a minimum top width of 24 in. Wide top widths and flat slopes are usually needed at crossings for construction traffic. • The outlet from the earth dike must function with a minimum of erosion. Runoff should be conveyed to a sediment trapping device such as a Sediment Trap (SE-s) or Sediment Basin November 2009 California Stormwater BMP Handbook 3 of 7 Construction www.casqa.org Earth Dikes and Drainage Swales EC-9 (SE-2) when either the dike channel or the drainage area above the dike are not adequately stabilized. • Temporary stabilization may be achieved using seed and mulching for slopes less than 5% and either rip-rap or sod for slopes in excess of 5%. In either case, stabilization of the earth dike should be completed immediately after construction or prior to the first rain. • If riprap is used to stabilize the channel formed along the toe of the dike, the following typical specifications apply: Channel Grade 0.5-1.0% 1.1-2.0% 2.1-4.O% 4.1-5.O% Riprap Stabilization 4 ia. Rock 6 in. Rock 8 in. Rock 8 in. -12 in. Riprap • The stone riprap, recycled concrete, etc. used for stabilization should be pressed into the soil with construction equipment. • Filter cloth may be used to cover dikes in use for long periods. • Construction activity on the earth dike should be kept to a minimum. Drainage Swales Drainage swales are only effective if they are properly installed. Swales are more effective than dikes because they tend to be more stable. The combination of a swale with a dike on the downhill side is the most cost effective diversion. Standard engineering design criteria for small open channel and closed conveyance systems should be used (see the local drainage design manual). Unless local drainage design criteria state otherwise, drainage swales should be designed as follows: • No more than 5 acres may drain to a temporary drainage swale. • Place drainage swales above or below, not on, a cut or fill slope. • Swale bottom width should be at least 2 ft • Depth of the swale should be at least 18 in. • Side slopes should be 2:1 or flatter. • Drainage or swales should be laid at a grade of at least i percent, but not more than 15 percent. • The swale must not be overtopped by the peak discharge from a lo-year storm, irrespective of the design criteria stated above. November 2009 California Stormwater BMP Handbook Construction www.casqa.org 4 of 7 Earth Dikes and Drainage Swales EC-9 • Remove all trees, stumps, obstructions, and other objectionable material from the swale when it is built. • Compact any fill material along the path of the swale. • Stabilize all swales immediately. Seed and mulch swales at a slope of less than 5 percent, and use rip-rap or sod for swales with a slope between 5 and 15 percent. For temporary swales, geotextiles and mats (EC-y) may provide immediate stabilization. • Irrigation may be required to establish sufficient vegetation to prevent erosion. • Do not operate construction vehicles across a swale unless a stabilized crossing is provided. • Permanent drainage facilities must be designed by a professional engineer (see the local drainage design criteria for proper design). • At a minimum, the drainage swale should conform to predevelopment drainage patterns and capacities. • Construct the drainage swale with a positive grade to a stabilized outlet. • Provide erosion protection or energy dissipation measures if the flow out of the drainage swale can reach an erosive velocity. Costs • Cost ranges from $15 to $55 per ft for both earthwork and stabilization and depends on availability of material, site location, and access. • Small dikes: $2.50 - $6-5O/linear ft; Large dikes: $2.5O/yd3. • The cost of a drainage swale increases with drainage area and slope. Typical swales for controlling internal erosion are inexpensive, as they are quickly formed during routine earthwork. Inspection and Maintenance • Inspect BMPs prior to forecast rain, daily during extended rain events, after rain events, weekly during the rainy season, and at two-week intervals during the non-rainy season. • Inspect BMPs subject to non-stormwater discharges daily while non-stormwater discharges occur. • Inspect ditches and berms for washouts. Replace lost riprap, damaged linings or soil stabilizers as needed. • Inspect channel linings, embankments, and beds of ditches and berms for erosion and accumulation of debris and sediment. Remove debris and sediment and repair linings and embankments as needed. • Temporary conveyances should be completely removed as soon as the surrounding drainage area has been stabilized or at the completion of construction November 2009 California Stormwater BMP Handbook 5 of 7 Construction www.casqa.org Earth Dikes and Drainage Swales EC-9 References Erosion and Sediment Control Handbook, S.J.

This can include soil testing (for seed base, soil characteristics, or nutrients), as well as roughening surface soils by mechanical methods (including sheepsfoot rolling, track walking, scarifying, stair stepping, and imprinting) to prepare soil for additional BMPs, or to break up sheet flow. Soil Preparation can also involve tilling topsoil to prepare a seed bed and/or incorporation of soil amendments, to enhance vegetative establishment. Suitable Applications Soil preparation: Soil preparation is essential to proper vegetative establishment. In particular, soil preparation (i.e. tilling, raking, and amendment) is suitable for use in combination with any soil stabilization method, including RECPs or sod. Soil preparation should not be confused with roughening. Roughening: Soil roughening is generally referred to as track walking (sometimes called imprinting) a slope, where treads from heavy equipment run parallel to the contours of the slope and act as mini terraces. Soil preparation is most effective when used in combination with erosion controls. Soil Roughening is suitable for use as a complementary process for controlling erosion on a site. Roughening is not intended to be used as a stand-alone BMP, and should be used with perimeter controls, additional erosion control measures, grade breaks, and vegetative establishment for maximum effectiveness. Roughening is intended to only affect surface soils and should not compromise slope stability or overall compaction. Suitable applications for soil roughening include: Categories EC SE TC WE NS WM Erosion Control Sediment Control Tracking Control Wind Erosion Control Non-Stormwater Management Control Waste Management and Materials Pollution Control 0 m Legend: 0 Primary Category @ Secondary Category Targeted Constituents Sediment [ Nutrients Trash Metals Bacteria Oil and Grease Organics Potential Alternatives EC-3 Hydraulic Mulch EC-5 Soil Binders EC-7 Geotextiles and Mats CALIfOHNIA STOUWMTEK November 2009 California Stonmwater BMP Handbook Construction www.casqa.org 1 of 4 Soil Preparation/Roughening EC-15 • Along any disturbed slopes, including temporary stockpiles, sediment basins, or compacted soil diversion berms and swales. • Roughening should be used in combination with hydraulically applied stabilization methods, compost blanket, or straw mulch; but should not be used in combination with RECPs or sod because roughening is intended to leave terraces on the slope. Limitations • Preparation and roughening must take place prior to installing other erosion controls (such as hydraulically applied stabilizers) or sediment controls (such as fiber rolls) on the faces of slopes. • In such cases where slope preparation is minimal, erosion control/revegetation BMPs that do not require extensive soil preparation - such as hydraulic mulching and seeding applications - should be employed. • Consideration should be given to the type of erosion control BMP that follows surface preparation, as some BMPs are not designed to be installed over various types of tillage/roughening, i.e., RECPs (erosion control blankets) should not be used with soil roughening due to a "bridging" effect, which suspends the blanket above the seed bed. • Surface roughness has an effect on the amount of mulch material that needs to be applied, which shows up as a general increase in mulch material due to an increase in surface area (Topographic Index -see EC-3 Hydraulic Mulching). Implementation • Additional guidance on the comparison and selection of temporary slope stabilization methods is provided in Appendix F of the Handbook. General A roughened surface can significantly reduce erosion. Based on tests done at the San Diego State Erosion Research Laboratory, various roughening techniques on slopes can result in a 12 - 76% reduction in the erosion rate versus smooth slopes. Materials Minimal materials are required unless amendments and/or seed are added to the soil. The majority of soil roughening/preparation can be done with equipment that is on hand at a normal construction site, such as bull dozers and compaction equipment. Installation Guidelines Soil Preparation • Where appropriate or feasible, soil should be prepared to receive the seed by disking or otherwise scarifying the surface to eliminate crust, improve air and water infiltration and create a more favorable environment for germination and growth. • Based upon soil testing conducted, apply additional soil amendments (e.g. fertilizers, additional seed) to the soil to help with germination. Follow EC-4, Hydroseeding, when selecting and applying seed and fertilizers. November 2009 California Stormwater BMP Handbook 2 of 4 Construction www.casqa.org Soil Preparation/Roughening EC-15 Cut Slope Roughening: • Stair-step grade or groove the cut slopes that are steeper than 3:1. • Use stair-step grading on any erodible material soft enough to be ripped with a bulldozer. Slopes consisting of soft rock with some subsoil are particularly suited to stair-step grading. • Make the vertical cut distance less than the horizontal distance, and slightly slope the horizontal position of the "step" in toward the vertical wall. • Do not make individual vertical cuts more than 2 feet (0.6 m) high in soft materials or more than 3 feet (0.9 m) high in rocky materials. • Groove the slope using machinery to create a series of ridges and depressions that run across the slope, on the contour. Fill Slope Roughening: • Place on fill slopes with a gradient steeper than 3:1 in lifts not to exceed 8 inches (0.2 m), and make sure each lift is properly compacted. • Ensure that the face of the slope consists of loose, uncompacted fill 4-6 inches (0.1-0.2 m) deep. • Use grooving or tracking to roughen the face of the slopes, if necessary. • Do not blade or scrape the final slope face. Roughening for Slopes to be Mowed: • Slopes which require mowing activities should not be steeper than 3:1. • Roughen these areas to shallow grooves by track walking, scarifying, sheepsfoot rolling, or imprinting. • Make grooves close together Qess than 10 inches), and not less than i inch deep, and perpendicular to the direction of runoff (i.e., parallel to the slope contours). • Excessive roughness is undesirable where mowing is planned. Roughening With Tracked Machinery: • Limit roughening with tracked machinery to soils with a sandy textural component to avoid undue compaction of the soil surface. • Operate tracked machinery up and down the slope to leave horizontal depressions in the soil. Do not back-blade during the final grading operation. • Seed and mulch roughened areas as soon as possible to obtain optimum seed germination and growth. November 2009 California Stormwater BMP Handbook 3 of 4 Construction www.casqa.org Soil Preparation/Roughening EC-15 Costs Costs are based on the additional labor of tracking or preparation of the slope plus the cost of any required soil amendment materials. Inspection and Maintenance • BMPs must be inspected in accordance with General Permit requirements for the associated project type and risk level. It is recommended that at a minimum, BMPs be inspected weekly, prior to forecasted rain events, daily during extended rain events, and after the conclusion of rain events. • Check the seeded slopes for signs of erosion such as rills and gullies. Fill these areas slightly above the original grade, then reseed and mulch as soon as possible. • Inspect BMPs weekly during normal operations, prior to forecasted rain events, daily during extended rain events, and after the conclusion of rain events.

November 2009 California Stormwater BMP Handbook 4 of 4 Construction www.casqa.org Silt Fence -1 Categories Description and Purpose A silt fence is made of a woven geotextile that has been entrenched, attached to supporting poles, and sometimes backed by a plastic or wire mesh for support. The silt fence detains sediment-laden water, promoting sedimentation behind the fence. Suitable Applications Silt fences are suitable for perimeter control, placed below areas where sheet flows discharge from the site. They could also be used as interior controls below disturbed areas where runoff may occur in the form of sheet and rill erosion and around inlets within disturbed areas (SE-io). Silt fences are generally ineffective in locations where the flow is concentrated and are only applicable for sheet or overland flows. Silt fences are most effective when used in combination with erosion controls. Suitable applications include: • Along the perimeter of a project. • Below the toe or down slope of exposed and erodible slopes. • Along streams and channels. • Around temporary spoil areas and stockpiles. • Around inlets. • Below other small cleared areas.

Runoff typically ponds temporarily on the upstream side of silt fence. • Do not use silt fence to divert water flows or place across any contour line. Fences not constructed on a level contour, or fences used to divert flow will concentrate flows resulting in additional erosion and possibly overtopping or failure of the silt fence. • Improperly installed fences are subject to failure from undercutting, overtopping, or collapsing. • Not effective unless trenched and keyed in. • Not intended for use as mid-slope protection on slopes greater than 4:1 (H:V). • Do not use on slopes subject to creeping, slumping, or landslides. Implementation General A silt fence is a temporary sediment barrier consisting of woven geotextile stretched across and attached to supporting posts, trenched-in, and, depending upon the strength of fabric used, supported with plastic or wire mesh fence. Silt fences trap sediment by intercepting and detaining small amounts of sediment-laden runoff from disturbed areas in order to promote sedimentation behind the fence. The following layout and installation guidance can improve performance and should be followed: • Use principally in areas where sheet flow occurs. • Install along a level contour, so water does not pond more than 1.5 ft at any point along the silt fence. • The maximum length of slope draining to any point along the silt fence should be 200 ft or less. • The maximum slope perpendicular to the fence line should be 1:1. • Provide sufficient room for runoff to pond behind the fence and to allow sediment removal equipment to pass between the silt fence and toes of slopes or other obstructions. About 1200 ft2 of ponding area should be provided for every acre draining to the fence. • Turn the ends of the filter fence uphill to prevent stormwater from flowing around the fence. • Leave an undisturbed or stabilized area immediately down slope from the fence where feasible. November 2009 California Stormwater BMP Handbook 2 of 8 Construction www.casqa.org Silt Fence SE-1 • Silt fences should remain in place until the disturbed area is permanently stabilized, after which, the silt fence should be removed and properly disposed. • Silt fence should be used in combination with erosion source controls up slope in order to provide the most effective sediment control. • Be aware of local regulations regarding the type and installation requirements of silt fence, which may differ from those presented in this fact sheet. Design and Layout The fence should be supported by a plastic or wire mesh if the fabric selected does not have sufficient strength and bursting strength characteristics for the planned application (as recommended by the fabric manufacturer). Woven geotextile material should contain ultraviolet inhibitors and stabilizers to provide a minimum of six months of expected usable construction life at a temperature range of o °F to 120 °F. • ' Layout in accordance with attached figures. • For slopes steeper than 2:1 (H:V) and that contain a high number of rocks or large dirt clods that tend to dislodge, it may be necessary to install additional protection immediately adjacent to the bottom of the slope, prior to installing silt fence. Additional protection may be a chain link fence or a cable fence. • For slopes adjacent to sensitive receiving waters or Environmentally Sensitive Areas (ESAs), silt fence should be used in conjunction with erosion control BMPs. Standard vs. Heavy Duty Silt Fence Standard Silt Fence • Generally applicable in cases where the slope of area draining to the silt fence is 4: i (H:V) or less. • Used for shorter durations, typically 5 months or less • Area draining to fence produces moderate sediment loads. Heavy Duty Silt Fence m Use is generally limited to 8 months or less. • Area draining to fence produces moderate sediment loads. • Heavy duty silt fence usually has i or more of the following characteristics, not possessed by standard silt fence. o Fence fabric has higher tensile strength. o Fabric is reinforced with wire backing or additional support. o Posts are spaced closer than pre-manufactured, standard silt fence products. o Posts are metal (steel or aluminum) Materials Standard Silt Fence • Silt fence material should be woven geotextile with a minimum width of 36 in. and a minimum tensile strength of 100 Ib force. The fabric should conform to the requirements in ASTM designation 04632 and should have an integral reinforcement layer. The November 2009 California Stormwater BMP Handbook 3 of 8 Construction www.casqa.org Silt Fence SE-1 reinforcement layer should be a polypropylene, or equivalent, net provided by the manufacturer. The permittivity of the fabric should be between o.i sec'1 and 0.15 sec"1 in conformance with the requirements in ASTM designation 04491. • Wood stakes should be commercial quality lumber of the size and shape shown on the plans. Each stake should be free from decay, splits or cracks longer than the thickness of the stake or other defects that would weaken the stakes and cause the stakes to be structurally unsuitable. • Staples used to fasten the fence fabric to the stakes should be not less than 1.75 in. long and should be fabricated from 15 gauge or heavier wire. The wire used to fasten the tops of the stakes together when joining two sections of fence should be 9 gauge or heavier wire. Galvanizing of the fastening wire will not be required. Heavy-Duty Silt Fence • Some silt fence has a wire backing to provide additional support, and there are products that may use prefabricated plastic holders for the silt fence and use metal posts or bar reinforcement instead of wood stakes. If bar reinforcement is used in lieu of wood stakes, use number four or greater bar. Provide end protection for any exposed bar reinforcement for health and safety purposes. Installation Guidelines - Traditional Method Silt fences are to be constructed on a level contour. Sufficient area should exist behind the fence for ponding to occur without flooding or overtopping the fence. • A trench should be excavated approximately 6 in. wide and 6 in. deep along the line of the proposed silt fence (trenches should not be excavated wider or deeper than necessary for proper silt fence installation). • Bottom of the silt fence should be keyed-in a minimum of 12 in. • Posts should be spaced a maximum of 6 ft apart and driven securely into the ground a minimum of 18 in. or 12 in. below the bottom of the trench. • When standard strength geotextile is used, a plastic or wire mesh support fence should be fastened securely to the upslope side of posts using heavy-duty wire staples at least i in. long. The mesh should extend into the trench. • When extra-strength geotextile and closer post spacing are used, the mesh support fence may be eliminated. • Woven geotextile should be purchased in a long roll, then cut to the length of the barrier. When joints are necessary, geotextile should be spliced together only at a support post, with a minimum 6 in. overlap and both ends securely fastened to the post. • The trench should be backfilled with native material and compacted. • Construct silt fences with a setback of at least 3 ft from the toe of a slope. Where, due to specific site conditions, a 3 ft setback is not available, the silt fence may be constructed at the November 2009 California Stormwater BMP Handbook 4 of 8 Construction www.casqa.org Silt Fence SE-1 toe of the slope, but should be constructed as far from the toe of the slope as practicable. Silt fences close to the toe of the slope will be less effective and more difficult to maintain. • Construct the length of each reach so that the change in base elevation along the reach does not exceed 1/3 the height of the barrier; in no case should the reach exceed 500 ft. • Cross barriers should be a minimum of l/3 and a maximum of l/2 the height of the linear barrier. • See typical installation details at the end of this fact sheet. Installation Guidelines - Static Slicing Method • Static Slicing is defined as insertion of a narrow blade pulled behind a tractor, similar to a plow blade, at least 10 inches into the soil while at the same time pulling silt geotextile fabric into the ground through the opening created by the blade to the depth of the blade. Once the gerotextile is installed, the soil is compacted using tractor tires. • This method will not work with pre-fabricated, wire backed silt fence. • Benefits: o Ease of installation (most often done with a 2 person crew). In addition, installation using static slicing has been found to be more efficient on slopes, in rocky soils, and in saturated soils. o Minimal soil disturbance. o Greater level of compaction along fence, leading to higher performance (i.e. greater sediment retention). o Uniform installation. o Less susceptible to undercutting/undermining. Costs • It should be noted that costs vary greatly across regions due to available supplies and labor costs. • Average annual cost for installation using the traditional silt fence installation method (assumes 6 month useful life) is $7 per linear foot based on vendor research. Range of cost is $3.50 - $9.10 per linear foot. • In tests, the slicing method required 0.33 man hours per 100 linear feet, while the trenched based systems required as much as 1.01 man hours per linear foot. Inspection and Maintenance • BMPs must be inspected in accordance with General Permit requirements for the associated project type and risk level. It is recommended that at a minimum, BMPs be inspected weekly, prior to forecasted rain events, daily during extended rain events, and after the conclusion of rain events. • Repair undercut silt fences. November 2009 California Stormwater BMP Handbook 5 of 8 Construction www.casqa.org Silt Fence SE-1 • Repair or replace split, torn, slumping, or weathered fabric. The lifespan of silt fence fabric is generally 5 to 8 months. • Silt fences that are damaged and become unsuitable for the intended purpose should be removed from the site of work, disposed, and replaced with new silt fence barriers. • Sediment that accumulates in the BMP should be periodically removed in order to maintain BMP effectiveness. Sediment should be removed when the sediment accumulation reaches one-third of the barrier height. • Silt fences should be left in place until the upstream area is permanently stabilized. Until then, the silt fence should be inspected and maintained regularly. • Remove silt fence when upgradient areas are stabilized. Fill and compact post holes and anchor trench, remove sediment accumulation, grade fence alignment to blend with adjacent ground, and stabilize disturbed area.

Check dams reduce the effective slope of the channel, thereby reducing scour and channel erosion by reducing flow velocity and increasing residence time within the channel, allowing sediment to settle. Suitable Applications Check dams may be appropriate in the following situations: • To promote sedimentation behind the dam. • To prevent erosion by reducing the velocity of channel flow in small intermittent channels and temporary swales. • In small open channels that drain 10 acres or less. • In steep channels where stormwater runoff velocities exceed 5 ft/s. • During the establishment of grass linings in drainage ditches or channels. • In temporary ditches where the short length of service does not warrant establishment of erosion-resistant linings. • To act as a grade control structure.

Implementation General Check dams reduce the effective slope and create small pools in swales and ditches that drain 10 acres or less. Using check dams to reduce channel slope reduces the velocity of stormwater flows, thus reducing erosion of the swale or ditch and promoting sedimentation. Thus, check dams are dual-purpose and serve an important role as erosion controls as well as as sediment controls. Note that use of 1-2 isolated check dams for sedimentation will likely result in little net removal of sediment because of the small detention time and probable scour during longer storms. Using a series of check dams will generally increase their effectiveness. A sediment trap (SE-s) may be placed immediately upstream of the check dam to increase sediment removal efficiency. Design and Layout Check dams work by decreasing the effective slope in ditches and swales. An important consequence of the reduced slope is a reduction in capacity of the ditch or swale. This reduction in capacity should be considered when using this BMP, as reduced capacity can result in overtopping of the ditch or swale and resultant consequences. In some cases, such as a "permanent" ditch or swale being constructed early and used as a "temporary" conveyance for construction flows, the ditch or swale may have sufficient capacity such that the temporary reduction in capacity due to check dams is acceptable. When check dams reduce capacities beyond acceptable limits, either: • Don't use check dams. Consider alternative BMPs, or. • Increase the size of the ditch or swale to restore capacity. Maximum slope and velocity reduction is achieved when the toe of the upstream dam is at the same elevation as the top of the downstream dam (see "Spacing Between Check Dams" detail at the end of this fact sheet). The center section of the dam should be lower than the edge sections (at least 6 inches), acting as a spillway, so that the check dam will direct flows to the center of November 2009 California Stormwater BMP Handbook 2 of 7 Construction www.casqa.org Check Dams SE-4 the ditch or swale (see "Typical Rock Check Dam" detail at the end of this fact sheet). Bypass or side-cutting can occur if a sufficient spillway is not provided in the center of the dam. Check dams are usually constructed of rock, gravel bags, sandbags, and fiber rolls. A number of products can also be used as check dams (e.g. HDPE check dams, temporary silt dikes (SE-12)), and some of these products can be removed and reused. Check dams can also be constructed of logs or lumber, and have the advantage of a longer lifespan when compared to gravel bags, sandbags, and fiber rolls. Check dams should not be constructed from straw bales or silt fences, since concentrated flows quickly wash out these materials. Rock check dams are usually constructed of 8 to 12 in. rock. The rock is placed either by hand or mechanically, but never just dumped into the channel. The dam should completely span the ditch or swale to prevent washout. The rock used should be large enough to stay in place given the expected design flow through the channel. It is recommended that abutments be extended 18 in. into the channel bank. Rock can be graded such that smaller diameter rock (e.g. 2-4 in) is located on the upstream side of larger rock (holding the smaller rock in place); increasing residence time. Log check dams are usually constructed of 4 to 6 in. diameter logs, installed vertically. The logs should be embedded into the soil at least 18 in. Logs can be bolted or wired to vertical support logs that have been driven or buried into the soil. See fiber rolls, SE-5, for installation of fiber roll check dams. Gravel bag and sand bag check dams are constructed by stacking bags across the ditch or swale, shaped as shown in the drawings at the end of this fact sheet (see "Gravel Bag Check Dam" detail at the end of this fact sheet). Manufactured products, such as temporary silt dikes (SE-12), should be installed in accordance with the manufacturer's instructions. Installation typically requires anchoring or trenching of products, as well as regular maintenance to remove accumulated sediment and debris. If grass is planted to stabilize the ditch or swale, the check dam should be removed when the grass has matured (unless the slope of the swales is greater than 4%). The following guidance should be followed for the design and layout of check dams: • Install the first check dam approximately 16 ft from the outfall device and at regular intervals based on slope gradient and soil type. • Check dams should be placed at a distance and height to allow small pools to form between each check dam. • For multiple check dam installation, backwater from a downstream check dam should reach the toes of the upstream check dam. • A sediment trap provided immediately upstream of the check dam will help capture sediment. Due to the potential for this sediment to be resuspended in subsequent storms, the sediment trap should be cleaned following each storm event. November 2009 California Stormwater BMP Handbook 3 of 7 Construction www.casqa.org Check Dams SE-4 • High flows (typically a 2-year storm or larger) should safely flow over the check dam without an increase in upstream flooding or damage to the check dam. • Where grass is used to line ditches, check dams should be removed when grass has matured sufficiently to protect the ditch or swale. Materials m Rock used for check dams should typically be 8-12 in rock and be sufficiently sized to stay in place given expected design flows in the channel. Smaller diameter rock (e.g. 2 to 4 in) can be placed on the upstream side of larger rock to increase residence time. • Gravel bags used for check dams should conform to the requirements of SE-6, Gravel Bag Berms. • Sandbags used for check dams should conform to SE-8, Sandbag Barrier. • Fiber rolls used for check dams should conform to SE-5, Fiber Rolls. • Temporary silt dikes used for check dams should conform to SE-12, Temporary Silt Dikes. InstaHation • Rock should be placed individually by hand or by mechanical methods (no dumping of rock) to achieve complete ditch or swale coverage. • Tightly abut bags and stack according to detail shown in the figure at the end of this section (pyramid approach). Gravel bags and sandbags should not be stacked any higher than 3 ft. • Upper rows or gravel and sand bags shall overlap joints in lower rows. • Fiber rolls should be trenched in, backfilled, and firmly staked in place. • Install along a level contour. • HDPE check dams, temporary silt dikes, and other manufactured products should be used and installed per manufacturer specifications. Costs Cost consists of labor costs if materials are readily available (such as gravel on-site). If material must be imported, costs will increase. For other material and installation costs, see SE-5, SE-6, SE-8, SE-12, and SE-14. Inspection and Maintenance • BMPs must be inspected in accordance with General Permit requirements for the associated project type and risk level. It is recommended that at a minimum, BMPs be inspected weekly, prior to forecasted rain events, daily during extended rain events, and after the conclusion of rain events. • Replace missing rock, bags, rolls, etc. Replace bags or rolls that have degraded or have become damaged. November 2009 California Stormwater BMP Handbook 4 of 7 Construction www.casqa.org Check Dams SE-4 • If the check dam is used as a sediment capture device, sediment that accumulates behind the BMP should be periodically removed in order to maintain BMP effectiveness. Sediment should be removed when the sediment accumulation reaches one-third of the barrier height. • If the check dam is used as a grade control structure, sediment removal is not required as long as the system continues to control the grade. • Inspect areas behind check dams for pools of standing water, especially if subjected to daily non-stormwater discharges. • Remove accumulated sediment prior to permanent seeding or soil stabilization. • Remove check dam and accumulated sediment when check dams are no longer needed.

Additionally, gravel core fiber rolls are available, which contain an imbedded ballast material such as gravel or sand for additional weight when staking the rolls are not feasible (such as use as inlet protection). When fiber rolls are placed at the toe and on the face of slopes along the contours, they intercept runoff, reduce its flow velocity, release the runoff as sheet flow, and provide removal of sediment from the runoff (through sedimentation). By interrupting the length of a slope, fiber rolls can also reduce sheet and rill erosion until vegetation is established. Suitable Applications Fiber rolls may be suitable: • Along the toe, top, face, and at grade breaks of exposed and credible slopes to shorten slope length and spread runoff as sheet flow. • At the end of a downward slope where it transitions to a steeper slope. • Along the perimeter of a project. • As check dams in unlined ditches with minimal grade. • Down-slope of exposed soil areas. • At operational storm drains as a form of inlet protection.

Limitations • Fiber rolls are not effective unless trenched in and staked. • Not intended for use in high flow situations. • Difficult to move once saturated. • If not properly staked and trenched in, fiber rolls could be transported by high flows. • Fiber rolls have a very limited sediment capture zone. • Fiber rolls should not be used on slopes subject to creep, slumping, or landslide. • Rolls typically function for 12-24 months depending upon local conditions. Implementation Fiber Roll Materials • Fiber rolls should be prefabricated. • Fiber rolls may come manufactured containing polyacrylamide (PAM), a flocculating agent within the roll. Fiber rolls impregnated with PAM provide additional sediment removal capabilities and should be used in areas with fine, clayey or silty soils to provide additional sediment removal capabilities. Monitoring may be required for these installations. • Fiber rolls are made from weed free rice straw, flax, or a similar agricultural material bound into a tight tubular roll by netting. • Typical fiber rolls vary in diameter from 9 in. to 20 in. Larger diameter rolls are available as well. Installation m Locate fiber rolls on level contours spaced as follows: Slope inclination of 4:1 (H:V) or flatter: Fiber rolls should be placed at a maximum interval of 20 ft. Slope inclination between 4:1 and 2:1 (H:V): Fiber Rolls should be placed at a maximum interval of 15 ft. (a closer spacing is more effective). Slope inclination 2:1 (H:V) or greater: Fiber Rolls should be placed at a maximum interval of 10 ft. (a closer spacing is more effective). • Prepare the slope before beginning installation. • Dig small trenches across the slope on the contour. The trench depth should be ¥4 to 1/3 of the thickness of the roll, and the width should equal the roll diameter, in order to provide area to backfill the trench. November 2009 California Stormwater BMP Handbook 2 of 5 Construction www.casqa.org Fiber Rolls SE-5 • It is critical that rolls are installed perpendicular to water movement, and parallel to the slope contour. • Start building trenches and installing rolls from the bottom of the slope and work up. • It is recommended that pilot holes be driven through the fiber roll. Use a straight bar to drive holes through the roll and into the soil for the wooden stakes. • Turn the ends of the fiber roll up slope to prevent runoff from going around the roll. • Stake fiber rolls into the trench. Drive stakes at the end of each fiber roll and spaced 4 ft maximum on center. Use wood stakes with a nominal classification of 0.75 by 0.75 in. and minimum length of 24 in. • If more than one fiber roll is placed in a row, the rolls should be overlapped, not abutted. • See typical fiber roll installation details at the end of this fact sheet. Removal • Fiber rolls can be left in place or removed depending on the type of fiber roll and application (temporary vs. permanent installation). Typically, fiber rolls encased with plastic netting are used for a temporary application because the netting does not biodegrade. Fiber rolls used in a permanent application are typically encased with a biodegradeable material and are left in place. Removal of a fiber roll used in a permanent application can result in greater disturbance. • Temporary installations should only be removed when up gradient areas are stabilized per General Permit requirements, and/or pollutant sources no longer present a hazard. But, they should also be removed before vegetation becomes too mature so that the removal process does not disturb more soil and vegetation than is necessary. Costs Material costs for regular fiber rolls range from $20 - $30 per 25 ft roll. Material costs for PAM impregnated fiber rolls range between 7.oo-$9.oo per linear foot, based upon vendor research. Inspection and Maintenance • BMPs must be inspected in accordance with General Permit requirements for the associated project type and risk level. It is recommended that at a minimum, BMPs be inspected weekly, prior to forecasted rain events, daily during extended rain events, and after the conclusion of rain events. • Repair or replace split, torn, unraveling, or slumping fiber rolls. • If the fiber roll is used as a sediment capture device, or as an erosion control device to maintain sheet flows, sediment that accumulates in the BMP should be periodically removed November 2009 California Stormwater BMP Handbook 3 of 5 Construction www.casqa.org Fiber Rolls SE-5 in order to maintain BMP effectiveness. Sediment should be removed when sediment accumulation reaches one-third the designated sediment storage depth. • If fiber rolls are used for erosion control, such as in a check dam, sediment removal should not be required as long as the system continues to control the grade. Sediment control BMPs will likely be required in conjunction with this type of application. • Repair any rills or gullies promptly.

Storm drain inlet protection measures temporarily pond runoff before it enters the storm drain, allowing sediment to settle. Some filter configurations also remove sediment by filtering, but usually the ponding action results in the greatest sediment reduction. Temporary geotextile storm drain inserts attach underneath storm drain grates to capture and filter storm water. Suitable Applications Every storm drain inlet receiving runoff from unstabilized or otherwise active work areas should be protected. Inlet protection should be used in conjunction with other erosion and sediment controls to prevent sediment-laden stormwater and non-storm water discharges from entering the storm drain system. Limitations • Drainage area should not exceed i acre. • In general straw bales should not be used as inlet protection. • Requires an adequate area for water to pond without encroaching into portions of the roadway subject to traffic.

If high flow conditions are expected, use other onsite sediment trapping techniques in conjunction with inlet protection. • Frequent maintenance is required. • Limit drainage area to i acre maximum. For drainage areas larger than i acre, runoff should be routed to a sediment-trapping device designed for larger flows. See BMPs SE-2, Sediment Basin, and SE-3, Sediment Traps. • Excavated drop inlet sediment traps are appropriate where relatively heavy flows are expected, and overflow capability is needed. Implementation General Inlet control measures presented in this handbook should not be used for inlets draining more than one acre. Runoff from larger disturbed areas should be first routed through SE-2, Sediment Basin or SE-3, Sediment Trap and/or used in conjunction with other drainage control, erosion control, and sediment control BMPs to protect the site. Different types of inlet protection are appropriate for different applications depending on site conditions and the type of inlet. Alternative methods are available in addition to the methods described/shown herein such as prefabricated inlet insert devices, or gutter protection devices. Design and Layout Identify existing and planned storm drain inlets that have the potential to receive sediment- laden surface runoff. Determine if storm drain inlet protection is needed and which method to use. • The key to successful and safe use of storm drain inlet protection devices is to know where runoff that is directed toward the inlet to be protected will pond or be diverted as a result of installing the protection device. Determine the acceptable location and extent of ponding in the vicinity of the drain inlet. The acceptable location and extent of ponding will influence the type and design of the storm drain inlet protection device. Determine the extent of potential runoff diversion caused by the storm drain inlet protection device. Runoff ponded by inlet protection devices may flow around the device and towards the next downstream inlet. In some cases, this is acceptable; in other cases, serious erosion or downstream property damage can be caused by these diversions. The possibility of runoff diversions will influence whether or not storm drain inlet protection is suitable; and, if suitable, the type and design of the device. • The location and extent of ponding, and the extent of diversion, can usually be controlled through appropriate placement of the inlet protection device. In some cases, moving the inlet protection device a short distance upstream of the actual inlet can provide more efficient sediment control, limit ponding to desired areas, and prevent or control diversions. November 2009 California Stormwater BMP Handbook 2 of 10 Construction www.casqa.org Storm Drain Inlet Protection SE-10 • Six types of inlet protection are presented below. However, it is recognized that other effective methods and proprietary devices exist and may be selected. Silt Fence: Appropriate for drainage basins with less than a 5% slope, sheet flows, and flows under 0.5 cfs. Excavated Drop Inlet Sediment Trap: An excavated area around the inlet to trap sediment (SE-3). Gravel bag barrier: Used to create a small sediment trap upstream of inlets on sloped, paved streets. Appropriate for sheet flow or when concentrated flow may exceed 0.5 cfs, and where overtopping is required to prevent flooding. Block and Gravel Filter: Appropriate for flows greater than 0.5 cfs. Temporary Geotextile Storm drain Inserts: Different products provide different features. Refer to manufacturer details for targeted pollutants and additional features. Biofilter Bag Barrier: Used to create a small retention area upstream of inlets and can be located on pavement or soil. Biofilter bags slowly filter runoff allowing sediment to settle out. Appropriate for flows under 0.5 cfs. • Select the appropriate type of inlet protection and design as referred to or as described in this fact sheet. • Provide area around the inlet for water to pond without flooding structures and property. • Grates and spaces around all inlets should be sealed to prevent seepage of sediment-laden water. • Excavate sediment sumps (where needed) i to 2 ft with 2:1 side slopes around the inlet. Installation m DI Protection Type i - Silt Fence - Similar to constructing a silt fence; see BMP SE-i, Silt Fence. Do not place fabric underneath the inlet grate since the collected sediment may fall into the drain inlet when the fabric is removed or replaced and water flow through the grate will be blocked resulting in flooding. See typical Type l installation details at the end of this fact sheet. 1. Excavate a trench approximately 6 in. wide and 6 in. deep along the line of the silt fence inlet protection device. 2. Place 2 in. by 2 in. wooden stakes around the perimeter of the inlet a maximum of 3 ft apart and drive them at least 18 in. into the ground or 12 in. below the bottom of the trench. The stakes should be at least 48 in. 3. Lay fabric along bottom of trench, up side of trench, and then up stakes. See SE-i, Silt Fence, for details. The maximum silt fence height around the inlet is 24 in. 4. Staple the filter fabric (for materials and specifications, see SE-i, Silt Fence) to wooden stakes. Use heavy-duty wire staples at least i in. in length. November 2009 California Stormwater BMP Handbook 3 of 10 Construction www.casqa.org Storm Drain Inlet Protection SE-10 5. Backfill the trench with gravel or compacted earth all the way around. DI Protection Type 2 - Excavated Drop Inlet Sediment Trap - Install filter fabric fence in accordance with DI Protection Type i. Size excavated trap to provide a minimum storage capacity calculated at the rate 67 yds/acre of drainage area. See typical Type 2 installation details at the end of this fact sheet. DI Protection Type 3 - Gravel bag - Flow from a severe storm should not overtop the curb. In areas of high clay and silts, use filter fabric and gravel as additional filter media. Construct gravel bags in accordance with SE-6, Gravel Bag Berm. Gravel bags should be used due to their high permeability. See typical Type 3 installation details at the end of this fact sheet. 1. Construct on gently sloping street. 2. Leave room upstream of barrier for water to pond and sediment to settle. 3. Place several layers of gravel bags - overlapping the bags and packing them tightly together. 4. Leave gap of one bag on the top row to serve as a spillway. Flow from a severe storm (e.g., 10 year storm) should not overtop the curb. DI Protection Type 4 — Block and Gravel Filter - Block and gravel filters are suitable for curb inlets commonly used in residential, commercial, and industrial construction. See typical Type 4 installation details at the end of this fact sheet. 1. Place hardware cloth or comparable wire mesh with 0.5 in. openings over the drop inlet so that the wire extends a minimum of i ft beyond each side of the inlet structure. If more than one strip is necessary, overlap the strips. Place woven geotextile over the wire mesh. 2. Place concrete blocks lengthwise on their sides in a single row around the perimeter of the inlet, so that the open ends face outward, not upward. The ends of adjacent blocks should abut. The height of the barrier can be varied, depending on design needs, by stacking combinations of blocks that are 4 in., 8 in., and 12 in. wide. The row of blocks should be at least 12 in. but no greater than 24 in. high. 3. Place wire mesh over the outside vertical face (open end) of the concrete blocks to prevent stone from being washed through the blocks. Use hardware cloth or comparable wire mesh with 0.5 in. opening. 4. Pile washed stone against the wire mesh to the top of the blocks. Use 0.75 to 3 in. DI Protection Type 5 — Temporary Geotextile Insert (proprietary) — Many types of temporary inserts are available. Most inserts fit underneath the grate of a drop inlet or inside of a curb inlet and are fastened to the outside of the grate or curb. These inserts are removable and many can be cleaned and reused. Installation of these inserts differs between manufacturers. Please refer to manufacturer instruction for installation of proprietary devices. November 2009 California Stormwater BMP Handbook 4 of 10 Construction www.casqa.org Storm Drain Inlet Protection SE-10 • DI Protection Type 6 - Biofilter bags - Biofilter bags may be vised as a substitute for gravel bags in low-flow situations. Biofilter bags should conform to specifications detailed in SE-14, Biofilter bags. 1. Construct in a gently sloping area. 2. Biofilter bags should be placed around inlets to intercept runoff flows. 3. All bag joints should overlap by 6 in. 4. Leave room upstream for water to pond and for sediment to settle out. 5. Stake bags to the ground as described in the following detail. Stakes maybe omitted if bags are placed on a paved surface. Costs • Average annual cost for installation and maintenance of DI Type 1-4 and 6 (one year useful life) is $200 per inlet. • Temporary geotextile inserts are proprietary and cost varies by region. These inserts can often be reused and may have greater than i year of use if maintained and kept undamaged. Average cost per insert ranges from $50-75 plus installation, but costs can exceed $100. This cost does not include maintenance. Inspection and Maintenance • BMPs must be inspected in accordance with General Permit requirements for the associated project type and risk level. It is recommended that at a minimum, BMPs be inspected weekly, prior to forecasted rain events, daily during extended rain events, and after the conclusion of rain events. • Silt Fences. If the fabric becomes clogged, torn, or degrades, it should be replaced. Make sure the stakes are securely driven in the ground and are in good shape (i.e., not bent, cracked, or splintered, and are reasonably perpendicular to the ground). Replace damaged stakes. At a minimum, remove the sediment behind the fabric fence when accumulation reaches one-third the height of the fence or barrier height. • Gravel Filters. If the gravel becomes clogged with sediment, it should be carefully removed from the inlet and either cleaned or replaced. Since cleaning gravel at a construction site may be difficult, consider using the sediment-laden stone as fill material and put fresh stone around the inlet. Inspect bags for holes, gashes, and snags, and replace bags as needed. Check gravel bags for proper arrangement and displacement. • Sediment that accumulates in the BMP should be periodically removed in order to maintain BMP effectiveness. Sediment should be removed when the sediment accumulation reaches one-third of the barrier height. • Inspect and maintain temporary geotextile insert devices according to manufacturer's specifications. • Remove storm drain inlet protection once the drainage area is stabilized. November 2009 California Stormwater BMP Handbook 5 of 10 Construction www.casqa.org Storm Drain Inlet Protection SE-10 Clean and regrade area around the inlet and clean the inside of the storm drain inlet, as it should be free of sediment and debris at the time of final inspection.

Waste Management and Materials Pollution Control Legend: 0 Primary Category H Secondary Category Description and Purpose Wind erosion or dust control consists of applying water or other chemical dust suppressants as necessary to prevent or alleviate dust nuisance generated by construction activities. Covering small stockpiles or areas is an alternative to applying water or other dust palliatives. California's Mediterranean climate, with a short "wet" season and a typically long, hot "dry" season, allows the soils to thoroughly dry out. During the dry season, construction activities are at their peak, and disturbed and exposed areas are increasingly subject to wind erosion, sediment tracking and dust generated by construction equipment. Site conditions and climate can make dust control more of an erosion problem than water based erosion. Additionally, many local agencies, including Air Quality Management Districts, require dust control and/or dust control permits in order to comply with local nuisance laws, opacity laws (visibility impairment) and the requirements of the Clean Air Act. Wind erosion control is required to be implemented at all construction sites greater than i acre by the General Permit. Suitable Applications Most BMPs that provide protection against water-based erosion will also protect against wind-based erosion and dust control requirements required by other agencies will generally meet wind erosion control requirements for water quality protection. Wind erosion control BMPs are suitable during the following construction activities: Targeted Constituents Sediment Nutrients Trash Metals Bacteria Oil and Grease Organics 0 Potential Alternatives EC-5 Soil Binders November 2009 California Stormwater BMP Handbook Construction www.casqa.org lof 5 Wind Erosion Control WE-1 • Construction vehicle traffic on unpaved roads • Drilling and blasting activities • Soils and debris storage piles • Batch drop from front-end loaders • Areas with unstabilized soil • Final grading/site stabilization Limitations • Watering prevents dust only for a short period (generally less than a few hours) and should be applied daily (or more often) to be effective. • Over watering may cause erosion and track-out. • Oil or oil-treated subgrade should not be used for dust control because the oil may migrate into drainageways and/or seep into the soil. • Chemical dust suppression agents may have potential environmental impacts. Selected chemical dust control agents should be environmentally benign. • Effectiveness of controls depends on soil, temperature, humidity, wind velocity and traffic. • Chemical dust suppression agents should not be used within 100 feet of wetlands or water bodies. • Chemically treated subgrades may make the soil water repellant, interfering with long-term infiltration and the vegetation/re-vegetation of the site. Some chemical dust suppressants may be subject to freezing and may contain solvents and should be handled properly. • In compacted areas, watering and other liquid dust control measures may wash sediment or other constituents into the drainage system. • If the soil surface has minimal natural moisture, the affected area may need to be pre-wetted so that chemical dust control agents can uniformly penetrate the soil surface. Implementation Dust Control Practices Dust control BMPs generally stabilize exposed surfaces and minimize activities that suspend or track dust particles. The following table presents dust control practices that can be applied to varying site conditions that could potentially cause dust. For heavily traveled and disturbed areas, wet suppression (watering), chemical dust suppression, gravel asphalt surfacing, temporary gravel construction entrances, equipment wash-out areas, and haul truck covers can be employed as dust control applications. Permanent or temporary vegetation and mulching can be employed for areas of occasional or no construction traffic. Preventive measures include minimizing surface areas to be disturbed, limiting onsite vehicle traffic to 15 mph or less, and controlling the number and activity of vehicles on a site at any given time. November 2009 California Stormwater BMP Handbook 2 of 5 Construction www.casqa.org Wind Erosion Control WE-1 Chemical dust suppressants include: mulch and fiber based dust palliatives (e.g. paper mulch with gypsum binder), salts and brines (e.g. calcium chloride, magnesium chloride), non- petroleum based organics (e.g. vegetable oil, lignosulfonate), petroleum based organics (e.g. asphalt emulsion, dust oils, petroleum resins), synthetic polymers (e.g. polyvinyl acetate, vinyls, acrylic), clay additives (e.g. bentonite, montimorillonite) and electrochemical products (e.g. enzymes, ionic products).

Non-potable water should not be conveyed in tanks or drain pipes that will be used to convey potable water and there should be no connection between potable and non-potable supplies. Non-potable tanks, pipes, and other conveyances should be marked, "NON-POTABLE WATER - DO NOT DRINK." • Pave or chemically stabilize access points where unpaved traffic surfaces adjoin paved roads. • Provide covers for haul trucks transporting materials that contribute to dust. • Provide for rapid clean up of sediments deposited on paved roads. Furnish stabilized construction road entrances and wheel wash areas. • Stabilize inactive areas of construction sites using temporary vegetation or chemical stabilization methods. For chemical stabilization, there are many products available for chemically stabilizing gravel roadways and stockpiles. If chemical stabilization is used, the chemicals should not create any adverse effects on stormwater, plant life, or groundwater and should meet all applicable regulatory requirements. Costs Installation costs for water and chemical dust suppression vary based on the method used and the length of effectiveness. Annual costs may be high since some of these measures are effective for only a few hours to a few days. Inspection and Maintenance • Inspect and verify that activity-based BMPs are in place prior to the commencement of associated activities. • BMPs must be inspected in accordance with General Permit requirements for the associated project type and risk level. It is recommended that at a minimum, BMPs be inspected weekly, prior to forecasted rain events, daily during extended rain events, and after the conclusion of rain events. • Check areas protected to ensure coverage. • Most water-based dust control measures require frequent application, often dairy or even multiple times per day. Obtain vendor or independent information on longevity of chemical dust suppressants.

Implementation General A stabilized construction entrance is a pad of aggregate underlain with filter cloth located at any point where traffic will be entering or leaving a construction site to or from a public right of way, street, alley, sidewalk, or parking area. The purpose of a stabilized construction entrance is to reduce or eliminate the tracking of sediment onto public rights of way or streets. Reducing tracking of sediments and other pollutants onto paved roads helps prevent deposition of sediments into local storm drains and production of airborne dust. Where traffic will be entering or leaving the construction site, a stabilized construction entrance should be used. NPDES permits require that appropriate measures be implemented to prevent tracking of sediments onto paved roadways, where a significant source of sediments is derived from mud and dirt carried out from unpaved roads and construction sites. Stabilized construction entrances are moderately effective in removing sediment from equipment leaving a construction site. The entrance should be built on level ground. Advantages of the Stabilized Construction Entrance/Exit is that it does remove some sediment from equipment and serves to channel construction traffic in and out of the site at specified locations. Efficiency is greatly increased when a washing rack is included as part of a stabilized construction entrance/exit. Design and Layout • Construct on level ground where possible. • Select 3 to 6 in. diameter stones. • Use minimum depth of stones of 12 in. or as recommended by soils engineer. • Construct length of 50 ft minimum, and 30 ft minimum width. • Rumble racks constructed of steel panels with ridges and installed in the stabilized entrance/exit will help remove additional sediment and to keep adjacent streets clean. • Provide ample turning radii as part of the entrance. • Limit the points of entrance/exit to the construction site. • Limit speed of vehicles to control dust. • Properly grade each construction entrance/exit to prevent runoff from leaving the construction site. • Route runoff from stabilized entrances/exits through a sediment trapping device before discharge. • Design stabilized entrance/exit to support heaviest vehicles and equipment that will use it. November 2009 California Stormwater BMP Handbook 2 of 6 Construction www.casqa.org Stabilized Construction Entrance/Exit TC-1 • Select construction access stabilization (aggregate, asphaltic concrete, concrete) based on longevity, required performance, and site conditions. Do not use asphalt concrete (AC) grindings for stabilized construction access/roadway. • If aggregate is selected, place crushed aggregate over geotextile fabric to at least 12 in. depth, or place aggregate to a depth recommended by a geotechnical engineer. A crushed aggregate greater than 3 in. but smaller than 6 in. should be used. • Designate combination or single purpose entrances and exits to the construction site. • Require that all employees, subcontractors, and suppliers utilize the stabilized construction access. • Implement SE-7, Street Sweeping and Vacuuming, as needed. • All exit locations intended to be used for more than a two-week period should have stabilized construction entrance/exit BMPs. Inspection and Maintenance • Inspect and verify that activity-based BMPs are in place prior to the commencement of associated activities. While activities associated with the BMPs are under way, inspect weekly during the rainy season and of two-week intervals in the non-rainy season to verify continued BMP implementation. • Inspect local roads adjacent to the site dairy. Sweep or vacuum to remove visible accumulated sediment. • Remove aggregate, separate and dispose of sediment if construction entrance/exit is clogged with sediment. • Keep all temporary roadway ditches clear. • Check for damage and repair as needed. • Replace gravel material when surface voids are visible. • Remove all sediment deposited on paved roadways within 24 hours. • Remove gravel and filter fabric at completion of construction Costs Average annual cost for installation and maintenance may vary from $1,200 to $4,800 each, averaging $2,400 per entrance. Costs will increase with addition of washing rack, and sediment trap. With wash rack, costs range from $1,200 - $6,000 each, averaging $3,600 per entrance.

These practices can reduce or eliminate non-stormwater discharges. Suitable Applications Water conservation practices are suitable for all construction sites where water is used, including piped water, metered water, trucked water, and water from a reservoir. Limitations • None identified. Implementation • Keep water equipment in good working condition. • Stabilize water truck filling area. • Repair water leaks promptly. • Washing of vehicles and equipment on the construction site is discouraged. • Avoid using water to clean construction areas. If water must be used for cleaning or surface preparation, surface should be swept and vacuumed first to remove dirt. This will minimize amount of water required. • Direct construction water runoff to areas where it can soak EC SE TC WE NS WM Erosion Control Sediment Control Tracking Control Wind Erosion Control Non-Stormwater Management Control Waste Management and Materials Pollution Control H H 0 Legend: El Primary Objective 03 Secondary Objective Targeted Constituents Sediment [ Nutrients Trash Metals Bacteria Oil and Grease Organics Potential Alternatives None CALIFORNIA STOTMWATOl Ol'AI ITV XSSOClVltOS- November 2009 California Stormwater BMP Handbook Construction www.casqa.org Iof2 Water Conservation Practices NS-1 into the ground or be collected and reused. • Authorized non-stormwater discharges to the storm drain system, channels, or receiving waters are acceptable with the implementation of appropriate BMPs. • Lock water tank valves to prevent unauthorized use.

Suitable Applications This best management practice (BMP) applies to all construction projects. Illicit connection/discharge and reporting is applicable anytime an illicit connection or discharge is discovered or illegally dumped material is found on the construction site. Limitations Illicit connections and illegal discharges or dumping, for the purposes of this BMP, refer to discharges and dumping caused by parties other than the contractor. If pre-existing hazardous materials or wastes are known to exist onsite, they should be identified in the SWPPP and handled as set forth in the SWPPP. Implementation Planning • Review the SWPPP. Pre-existing areas of contamination should be identified and documented in the SWPPP. • Inspect site before beginning the job for evidence of illicit connections, illegal dumping or discharges. Document any pre-existing conditions and notify the owner. • Inspect site regularly during project execution for evidence EC SE TC WE NS WM Erosion Control Sediment Control Tracking Control Wind Erosion Control Non-Stormwater Management Control Waste Management and Materials Pollution Control 0 Legend: 0 Primary Objective 13 Secondary Objective Targeted Constituents Sediment Nutrients 0 Trash 0 Metals 0 Bacteria 0 Oil and Grease 0 Organics 0 Potential Alternatives None CAUfOKXUSTORMVVATrai}t;,M ITV \SSO<;UTI<.>S' November 2009 California Stormwater BMP Handbook Construction www.casqa.org Iof3 Illicit Connection/Discharge NS-6 of illicit connections, illegal dumping or discharges. • Observe site perimeter for evidence for potential of illicitly discharged or illegally dumped material, which may enter the job site. Identification of Illicit Connections and Illegal Dumping or Discharges m General — unlabeled and unidentifiable material should be treated as hazardous. • Solids - Look for debris, or rubbish piles. Solid waste dumping often occurs on roadways with light traffic loads or in areas not easily visible from the traveled way. • Liquids - signs of illegal liquid dumping or discharge can include: Visible signs of staining or unusual colors to the pavement or surrounding adjacent soils Pungent odors coming from the drainage systems Discoloration or oily substances in the water or stains and residues detained within ditches, channels or drain boxes Abnormal water flow during the dry weather season • Urban Areas - Evidence of illicit connections or illegal discharges is typically detected at storm drain outfall locations or at manholes. Signs of an illicit connection or illegal discharge can include: Abnormal water flow during the dry weather season Unusual flows in sub drain systems used for dewatering Pungent odors coming from the drainage systems Discoloration or oily substances in the water or stains and residues detained within ditches, channels or drain boxes Excessive sediment deposits, particularly adjacent to or near active offsite construction projects • Rural Areas - Illicit connections or illegal discharges involving irrigation drainage ditches are detected by visual inspections. Signs of an illicit discharge can include: Abnormal water flow during the non-irrigation season Non-standard junction structures Broken concrete or other disturbances at or near junction structures Reporting Notify the owner of any illicit connections and illegal dumping or discharge incidents at the time of discovery. For illicit connections or discharges to the storm drain system, notify the local stormwater management agency. For illegal dumping, notify the local law enforcement agency. Cleanup and Removal The responsibility for cleanup and removal of illicit or illegal dumping or discharges will vary by location. Contact the local stormwater management agency for further information. November 2009 California Stormwater BMP Handbook 2 of 3 Construction www.casqa.org Illicit Connection/Discharge NS-6 Costs Costs to look for and report illicit connections and illegal discharges and dumping are low. The best way to avoid costs associated with illicit connections and illegal discharges and dumping is to keep the project perimeters secure to prevent access to the site, to observe the site for vehicles that should not be there, and to document any waste or hazardous materials that exist onsite before taking possession of the site. Inspection and Maintenance • Inspect and verify that activity-based BMPs are in place prior to the commencement of associated activities. While activities associated with the BMP are under way, inspect weekly during the rainy season and at two-week intervals in the non-rainy season to verify continued BMP implementation. • Inspect the site regularly to check for any illegal dumping or discharge. • Prohibit employees and subcontractors from disposing of non-job related debris or materials at the construction site. • Notify the owner of any illicit connections and illegal dumping or discharge incidents at the time of discovery.

November 2009 California Stormwater BMP Handbook 3 of 3 Construction www.casqa.org Potable Water/Irrigation NS-7 Description and Purpose Potable Water/Irrigation consists of practices and procedures to manage the discharge of potential pollutants generated during discharges from irrigation water lines, landscape irrigation, lawn or garden watering, planned and unplanned discharges from potable water sources, water line flushing, and hydrant flushing. Suitable Applications Implement this BMP whenever potable water or irrigation water discharges occur at or enter a construction site. Limitations None identified. Implementation • Direct water from offsite sources around or through a construction site, where feasible, in a way that minimizes contact with the construction site. • Discharges from water line flushing should be reused for landscaping purposes where feasible. • Shut off the water source to broken lines, sprinklers, or valves as soon as possible to prevent excess water flow. • Protect downstream stormwater drainage systems and watercourses from water pumped or bailed from trenches excavated to repair water lines. • Inspect irrigated areas within the construction limits for Categories EC SE TC WE NS WM Erosion Control Sediment Control Tracking Control Wind Erosion Control Non-Stormwater Management Control .

Procedures and practices include but are not limited to: using offsite facilities; washing in designated, contained areas only; eliminating discharges to the storm drain by infiltrating the wash water; and training employees and subcontractors in proper cleaning procedures. Suitable Applications These procedures are suitable on all construction sites where vehicle and equipment cleaning is performed. Limitations Even phosphate-free, biodegradable soaps have been shown to be toxic to fish before the soap degrades. Sending vehicles/equipment offsite should be done in conjunction with TC-i, Stabilized Construction Entrance/Exit. Implementation Other options to washing equipment onsite include contracting with either an offsite or mobile commercial washing business. These businesses may be better equipped to handle and dispose of the wash waters properly. Performing this work offsite can also be economical by eliminating the need for a separate washing operation onsite. If washing operations are to take place onsite, then: Categories EC SE TC WE NS WM Erosion Control Sediment Control Tracking Control Wind Erosion Control Non-Stormwater ,-« Management Control Waste Management and Materials Pollution Control Legend: 0 Primary Objective 13 Secondary Objective Targeted Constituents Sediment 0 Nutrients 0 Trash Metals Bacteria Oil and Grease 0 Organics 0 Potential Alternatives None CALIFORNIA STORMWATEHOi/.uirv (.ssiKuruiv November 2009 California Stormwater BMP Handbook Construction www.casqa.org Iof3 Vehicle and Equipment Cleaning NS-8 • Use phosphate-free, biodegradable soaps. • Educate employees and subcontractors on pollution prevention measures. • Do not permit steam cleaning onsite. Steam cleaning can generate significant pollutant concentrates. • Cleaning of vehicles and equipment with soap, solvents or steam should not occur on the project site unless resulting wastes are fully contained and disposed of. Resulting wastes should not be discharged or buried, and must be captured and recycled or disposed according to the requirements of WM-io, Liquid Waste Management or WM-6, Hazardous Waste Management, depending on the waste characteristics. Minimize use of solvents. Use of diesel for vehicle and equipment cleaning is prohibited. • All vehicles and equipment that regularly enter and leave the construction site must be cleaned offsite. • When vehicle and equipment washing and cleaning must occur onsite, and the operation cannot be located within a structure or building equipped with appropriate disposal facilities, the outside cleaning area should have the following characteristics: - Located away from storm drain inlets, drainage facilities, or watercourses Paved with concrete or asphalt and bermed to contain wash waters and to prevent runon and runoff - Configured with a sump to allow collection and disposal of wash water No discharge of wash waters to storm drains or watercourses Used only when necessary • When cleaning vehicles and equipment with water: Use as little water as possible. High-pressure sprayers may use less water than a hose and should be considered Use positive shutoff valve to minimize water usage Facility wash racks should discharge to a sanitary sewer, recycle system or other approved discharge system and must not discharge to the storm drainage system, watercourses, or to groundwater Costs Cleaning vehicles and equipment at an offsite facility may reduce overall costs for vehicle and equipment cleaning by eliminating the need to provide similar services onsite. When onsite cleaning is needed, the cost to establish appropriate facilities is relatively low on larger, long- duration projects, and moderate to high on small, short-duration projects. November 2009 California Stormwater BMP Handbook 2 of 3 Construction www.casqa.org Vehicle and Equipment Cleaning NS-8 Inspection and Maintenance • Inspect and verify that activity-based BMPs are in place prior to the commencement of associated activities. While activities associated with the BMP are under way, inspect weekly during the rainy season and at two-week intervals in the non-rainy season to verify continued BMP implementation. • Inspect BMPs subject to non-stormwater discharges daily while non-stormwater discharges occur. • Inspection and maintenance is minimal, although some berm repair may be necessary. • Monitor employees and subcontractors throughout the duration of the construction project to ensure appropriate practices are being implemented. • Inspect sump regularly and remove liquids and sediment as needed. • Prohibit employees and subcontractors from washing personal vehicles and equipment on the construction site.

November 2009 California Stormwater BMP Handbook 3 of 3 Construction www.casqa.org Vehicle and Equipment Fueling NS-9 Categories Description and Purpose Vehicle equipment fueling procedures and practices are designed to prevent fuel spills and leaks, and reduce or eliminate contamination of stormwater. This can be accomplished by using offsite facilities, fueling in designated areas only, enclosing or covering stored fuel, implementing spill controls, and training employees and subcontractors in proper fueling procedures. Suitable Applications These procedures are suitable on all construction sites where vehicle and equipment fueling takes place. Limitations Onsite vehicle and equipment fueling should only be used where it is impractical to send vehicles and equipment offsite for fueling. Sending vehicles and equipment offsite should be done in conjunction with TC-i, Stabilized Construction Entrance/ Exit. Implementation • Use offsite fueling stations as much as possible. These businesses are better equipped to handle fuel and spills properly. Performing this work offsite can also be economical by eliminating the need for a separate fueling area at a site. • Discourage "topping-off" of fuel tanks. • Absorbent spill cleanup materials and spill kits should be available in fueling areas and on fueling trucks, and should EC SE TC WE NS WM Erosion Control Sediment Control Tracking Control Wind Erosbn Control Non-Stormwater Management Control Waste Management and Materials Pollution Control Legend: El Primary Objective B Secondary Objective Targeted Constituents Sediment Nutrients Trash Metals Bacteria Oil and Grease I Organics Potential Alternatives None November 2009 California Stormwater BMP Handbook Construction www.casqa.org Iof3 Vehicle and Equipment Fueling NS-9 be disposed of properly after use. • Drip pans or absorbent pads should be used during vehicle and equipment fueling, unless the fueling is performed over an impermeable surface in a dedicated fueling area. • Use absorbent materials on small spills. Do not hose down or bury the spill. Remove the adsorbent materials promptly and dispose of properly. • Avoid mobile fueling of mobile construction equipment around the site; rather, transport the equipment to designated fueling areas. With the exception of tracked equipment such as bulldozers and large excavators, most vehicles should be able to travel to a designated area with little lost time. • Train employees and subcontractors in proper fueling and cleanup procedures. • When fueling must take place onsite, designate an area away from drainage courses to be used. Fueling areas should be identified in the SWPPP. • Dedicated fueling areas should be protected from stormwater runon and runoff, and should be located at least 50 ft away from downstream drainage facilities and watercourses. Fueling must be performed on level-grade areas. • Protect fueling areas with berms and dikes to prevent runon, runoff, and to contain spills. • Nozzles used in vehicle and equipment fueling should be equipped with an automatic shutoff to control drips. Fueling operations should not be left unattended. • Use vapor recovery nozzles to help control drips as well as air pollution where required by Air Quality Management Districts (AQMD). • Federal, state, and local requirements should be observed for any stationary above ground storage tanks. Costs • All of the above measures are low cost except for the capital costs of above ground tanks that meet all local environmental, zoning, and fire codes. Inspection and Maintenance • Vehicles and equipment should be inspected each day of use for leaks. Leaks should be repaired immediately or problem vehicles or equipment should be removed from the project site. • Keep ample supplies of spill cleanup materials onsite. • Immediately clean up spills and properly dispose of contaminated soil and cleanup materials.

Implementation The following steps should be taken to minimize risk: • Chemicals must be stored in water tight containers with appropriate secondary containment or in a storage shed. • When a material storage area is located on bare soil, the area should be lined and bermed. • Use containment pallets or other practical and available solutions, such as storing materials within newly constructed buildings or garages, to meet material storage requirements. • Stack erodible landscape material on pallets and cover when not in use. • Contain all fertilizers and other landscape materials when not in use. • Temporary storage areas should be located away from vehicular traffic. • Material Safety Data Sheets (MSDS) should be available on-site for all materials stored that have the potential to effect water quality. • Construction site areas should be designated for material delivery and storage. • Material delivery and storage areas should be located away from waterways, if possible. Avoid transport near drainage paths or waterways. Surround with earth berms or other appropriate containment BMP. See EC-9, Earth Dikes and Drainage Swales. Place in an area that will be paved. • Storage of reactive, ignitable, or flammable liquids must comply with the fire codes of your area. Contact the local Fire Marshal to review site materials, quantities, and proposed storage area to determine specific requirements. See the Flammable and Combustible Liquid Code, NFPAso. • An up to date inventory of materials delivered and stored onsite should be kept. November 2009 California Stormwater BMP Handbook 2 of 5 Construction www.casqa.org Material Delivery and Storage WM-1 • Hazardous materials storage onsite should be minimized. • Hazardous materials should be handled as infrequently as possible. • Keep ample spill cleanup supplies appropriate for the materials being stored. Ensure that cleanup supplies are in a conspicuous, labeled area. • Employees and subcontractors should be trained on the proper material delivery and storage practices. • Employees trained in emergency spill cleanup procedures must be present when dangerous materials or liquid chemicals are unloaded. • If significant residual materials remain on the ground after construction is complete, properly remove and dispose of materials and any contaminated soil. See WM-7, Contaminated Soil Management. If the area is to be paved, pave as soon as materials are removed to stabilize the soil. Material Storage Areas and Practices • Liquids, petroleum products, and substances listed in 40 CFR Parts no, 117, or 302 should be stored in approved containers and drums and should not be overfilled. Containers and drums should be placed in temporary containment facilities for storage. • A temporary containment facility should provide for a spill containment volume able to contain precipitation from a 25 year storm event, plus the greater of 10% of the aggregate volume of all containers or 100% of the capacity of the largest container within its boundary, whichever is greater. » A temporary containment facility should be impervious to the materials stored therein for a minimum contact time of 72 hours. • A temporary containment facility should be maintained free of accumulated rainwater and spills. In the event of spills or leaks, accumulated rainwater and spills should be collected and placed into drums. These liquids should be handled as a hazardous waste unless testing determines them to be non-hazardous. All collected liquids or non-hazardous liquids should be sent to an approved disposal site. • Sufficient separation should be provided between stored containers to allow for spill cleanup and emergency response access. • Incompatible materials, such as chlorine and ammonia, should not be stored in the same temporary containment facility. • Materials should be covered prior to, and during rain events. • Materials should be stored in their original containers and the original product labels should be maintained in place in a legible condition. Damaged or otherwise illegible labels should be replaced immediately. November 2009 California Stormwater BMP Handbook 3 of 5 Construction www.casqa.org Material Delivery and Storage WM-1 • Bagged and boxed materials should be stored on pallets and should not be allowed to accumulate on the ground. To provide protection from wind and rain throughout the rainy season, bagged and boxed materials should be covered during non-working days and prior to and during rain events. • Stockpiles should be protected in accordance with WM-3, Stockpile Management. • Materials should be stored indoors within existing structures or completely enclosed storage sheds when available. • Proper storage instructions should be posted at all times in an open and conspicuous location. • An ample supply of appropriate spill clean up material should be kept near storage areas. • Also see WM-6, Hazardous Waste Management, for storing of hazardous wastes. Material Delivery Practices m Keep an accurate, up-to-date inventory of material delivered and stored onsite. • Arrange for employees trained in emergency spill cleanup procedures to be present when dangerous materials or liquid chemicals are unloaded. Spill Cleanup • Contain and clean up any spill immediately. • Properly remove and dispose of any hazardous materials or contaminated soil if significant residual materials remain on the ground after construction is complete. See WM-7, Contaminated Soil Management. • See WM-4, Spill Prevention and Control, for spills of chemicals and/or hazardous materials. • If spills or leaks of materials occur that are not contained and could discharge to surface waters, non-visible sampling of site discharge may be required. Refer to the General Permit or to your project specific Construction Site Monitoring Plan to determine if and where sampling is required. Cost • The largest cost of implementation may be in the construction of a materials storage area that is covered and provides secondary containment. Inspection and Maintenance • BMPs must be inspected in accordance with General Permit requirements for the associated project type and risk level. It is recommended that at a minimum, BMPs be inspected weekly, prior to forecasted rain events, daily during extended rain events, and after the conclusion of rain events. • Keep storage areas clean and well organized, including a current list of all materials onsite. • Inspect labels on containers for legibility and accuracy. November 2009 California Stormwater BMP Handbook 4 of 5 Construction www.casqa.org Material Delivery and Storage WM-1 • Repair or replace perimeter controls, containment structures, covers, and liners as needed to maintain proper function.

Implementation The following steps should be taken to minimize risk: • Minimize use of hazardous materials onsite. • Follow manufacturer instructions regarding uses, protective equipment, ventilation, flammability, and mixing of chemicals. • Train personnel who use pesticides. The California Department of Pesticide Regulation and county agricultural commissioners license pesticide dealers, certify pesticide applicators, and conduct onsite inspections. • The preferred method of termiticide application is soil injection near the existing or proposed structure foundation/slab; however, if not feasible, soil drench application of termiticides should follow EPA label guidelines and the following recommendations (most of which are applicable to most pesticide applications): • Do not treat soil that is water-saturated or frozen. • Application shall not commence within 24-hours of a predicted precipitation event with a 40% or greater probability. Weather tracking must be performed on a daily basis prior to termiticide application and during the period of termiticide application. • Do not allow treatment chemicals to runoff from the target area. Apply proper quantity to prevent excess runoff. Provide containment for and divert stormwater from application areas using berms or diversion ditches during application. • Dry season: Do not apply within 10 feet of storm drains. Do not apply within 25 feet of aquatic habitats (such as, but not limited to, lakes; reservoirs; rivers; permanent streams; marshes or ponds; estuaries; and commercial fish farm ponds). • Wet season: Do not apply within 50 feet of storm drains or aquatic habitats (such as, but not limited to, lakes; reservoirs; rivers; permanent streams; marshes or ponds; estuaries; and commercial fish farm ponds) unless a vegetative buffer is present (if so, refer to dry season requirements). • Do not make on-grade applications when sustained wind speeds are above 10 mph (at application site) at nozzle end height. • Cover treatment site prior to a rain event in order to prevent run-off of the pesticide into non-target areas. The treated area should be limited to a size that can be backfilled and/or covered by the end of the work shift. Backfilling or covering of the treated area shall be done by the end of the same work shift in which the application is made. • The applicator must either cover the soil him/herself or provide written notification of the above requirement to the contractor on site and to the person commissioning the November 2009 California Stormwater BMP Handbook 2 of 4 Construction www.casqa.org Material Use WM-2 application (if different than the contractor). If notice is provided to the contractor or the person commissioning the application, then they are responsible under the Federal Insecticide Fungicide, and Rodenticide Act (FIFRA) to ensure that: l) if the concrete slab cannot be poured over the treated soil within 24 hours of application, the treated soil is covered with a waterproof covering (such as polyethylene sheeting), and 2) the treated soil is covered if precipitation is predicted to occur before the concrete slab is scheduled to be poured. Do not over-apply fertilizers, herbicides, and pesticides. Prepare only the amount needed. Follow the recommended usage instructions. Over-application is expensive and environmentally harmful. Unless on steep slopes, till fertilizers into the soil rather than hydraulic application. Apply surface dressings in several smaller applications, as opposed to one large application, to allow time for infiltration and to avoid excess material being carried offsite by runoff. Do not apply these chemicals before predicted rainfall. Train employees and subcontractors in proper material use. Supply Material Safety Data Sheets (MSDS) for all materials. Dispose of latex paint and paint cans, used brushes, rags, absorbent materials, and drop cloths, when thoroughly dry and are no longer hazardous, with other construction debris. Do not remove the original product label; it contains important safety and disposal information. Use the entire product before disposing of the container. Mix paint indoors or in a containment area. Never clean paintbrushes or rinse paint containers into a street, gutter, storm drain, or watercourse. Dispose of any paint thinners, residue, and sludge(s) that cannot be recycled, as hazardous waste. For water-based paint, clean brushes to the extent practicable, and rinse to a drain leading to a sanitary sewer where permitted, or contain for proper disposal off site. For oil-based paints, clean brushes to the extent practicable, and filter and reuse thinners and solvents. Use recycled and less hazardous products when practical. Recycle residual paints, solvents, non-treated lumber, and other materials. Use materials only where and when needed to complete the construction activity. Use safer alternative materials as much as possible. Reduce or eliminate use of hazardous materials onsite when practical. Document the location, time, chemicals applied, and applicator's name and qualifications. Keep an ample supply of spill clean up material near use areas. Train employees in spill clean up procedures. Avoid exposing applied materials to rainfall and runoff unless sufficient time has been allowed for them to dry. Discontinue use of erodible landscape material within 2 days prior to a forecasted rain event and materials should be covered and/or bermed. November 2009 California Stormwater BMP Handbook 3 of 4 Construction www.casqa.org Material Use WM-2 • Provide containment for material use areas such as masons' areas or paint mixing/preparation areas to prevent materials/pollutants from entering stormwater. Costs All of the above are low cost measures. Inspection and Maintenance • Inspect and verify that activity-based BMPs are in place prior to the commencement of associated activities. • BMPs must be inspected in accordance with General Permit requirements for the associated project type and risk level. It is recommended that at a minimum, BMPs be inspected weekly, prior to forecasted rain events, daily during extended rain events, and after the conclusion of rain events. • Ensure employees and subcontractors throughout the job are using appropriate practices.

November 2009 California Stormwater BMP Handbook 4 of 4 Construction www.casqa.org Stockpile Management WM-3 Description and Purpose Stockpile management procedures and practices are designed to reduce or eliminate air and stormwater pollution from stockpiles of soil, soil amendments, sand, paving materials such as portiand cement concrete (PCC) rubble, asphalt concrete (AC), asphalt concrete rubble, aggregate base, aggregate sub base or pre-mixed aggregate, asphalt minder (so called "cold mix" asphalt), and pressure treated wood. Suitable Applications Implement in all projects that stockpile soil and other loose materials. Limitations • Plastic sheeting as a stockpile protection is temporary and hard to manage in windy conditions. Where plastic is used, consider use of plastic tarps with nylon reinforcement which may be more durable than standard sheeting. • Plastic sheeting can increase runoff volume due to lack of infiltration and potentially cause perimeter control failure. • Plastic sheeting breaks down faster in sunlight. • The use of Plastic materials and photodegradable plastics should be avoided.

Refer to the individual fact sheet for each of these controls for installation information. • Implement wind erosion control practices as appropriate on all stockpiled material. For specific information, see WE-i, Wind Erosion Control. • Manage stockpiles of contaminated soil in accordance with WM-y, Contaminated Soil Management. • Place bagged materials on pallets and under cover. • Ensure that stockpile coverings are installed securely to protect from wind and rain. • Some plastic covers withstand weather and sunlight better than others. Select cover materials or methods based on anticipated duration of use. Protection of Non-Active Stockpiles Non-active stockpiles of the identified materials should be protected further as follows: Soil stockpiles m Soil stockpiles should be covered or protected with soil stabilization measures and a temporary perimeter sediment barrier at all times. • Temporary vegetation should be considered for topsoil piles that will be stockpiled for extended periods. Stockpiles of Portland cement concrete rubble, asphalt concrete, asphalt concrete rubble, aggregate base, or aggregate sub base • Stockpiles should be covered and protected with a temporary perimeter sediment barrier at all times. Stockpiles of "cold mix" • Cold mix stockpiles should be placed on and covered with plastic sheeting or comparable material at all times and surrounded by a berm. Stockpiles of fly ash, stucco, hydrated lime m Stockpiles of materials that may raise the pH of runoff (i.e., basic materials) should be covered with plastic and surrounded by a berm. November 2009 California Stormwater BMP Handbook 2 of 3 Construction www.casqa.org Stockpile Management WM-3 Stockpiles/Storage of wood (Pressure treated with chromated copper arsenate or ammoniacal copper zinc arsenate • Treated wood should be covered with plastic sheeting or comparable material at all times and surrounded by a berm. Protection of Active Stockpiles Active stockpiles of the identified materials should be protected as follows: • All stockpiles should be covered and protected with a temporary linear sediment barrier prior to the onset of precipitation. • Stockpiles of "cold mix" and treated wood, and basic materials should be placed on and covered with plastic sheeting or comparable material and surrounded by a berm prior to the onset of precipitation. • The downstream perimeter of an active stockpile should be protected with a linear sediment barrier or berm and runoff should be diverted around or away from the stockpile on the upstream perimeter. Costs For cost information associated with stockpile protection refer to the individual erosion or sediment control BMP fact sheet considered for implementation (For example, refer to SE-i Silt Fence for installation of silt fence around the perimeter of a stockpile.) Inspection and Maintenance • Stockpiles must be inspected in accordance with General Permit requirements for the associated project type and risk level. It is recommended that at a minimum, BMPs be inspected weekly, prior to forecasted rain events, daily during extended rain events, and after the conclusion of rain events. • It may be necessary to inspect stockpiles covered with plastic sheeting more frequently during certain conditions (for example, high winds or extreme heat). • Repair and/or replace perimeter controls and covers as needed to keep them functioning properly. • Sediment shall be removed when it reaches one-third of the barrier height.

Contractor should identify appropriate practices for the specific materials used or stored onsite Implementation The following steps will help reduce the stormwater impacts of leaks and spills: Education m Be aware that different materials pollute in different amounts. Make sure that each employee knows what a "significant spill" is for each material they use, and what is the appropriate response for "significant" and "insignificant" spills. • Educate employees and subcontractors on potential dangers to humans and the environment from spills and leaks. • Hold regular meetings to discuss and reinforce appropriate disposal procedures (incorporate into regular safety meetings). • Establish a continuing education program to indoctrinate new employees. • Have contractor's superintendent or representative oversee and enforce proper spill prevention and control measures. General Measures • To the extent that the work can be accomplished safely, spills of oil, petroleum products, substances listed under 40 CFR parts 110,117, and 302, and sanitary and septic wastes should be contained and cleaned up immediately. • Store hazardous materials and wastes in covered containers and protect from vandalism. • Place a stockpile of spill cleanup materials where it will be readily accessible. • Train employees in spill prevention and cleanup. • Designate responsible individuals to oversee and enforce control measures. • Spills should be covered and protected from stormwater runon during rainfall to the extent that it doesn't compromise clean up activities. • Do not bury or wash spills with water. November 2009 California Stormwater BMP Handbook 2 of 6 Construction www.casqa.org Spill Prevention and Control WM-4 • Store and dispose of used clean up materials, contaminated materials, and recovered spill material that is no longer suitable for the intended purpose in conformance with the provisions in applicable BMPs. • Do not allow water used for cleaning and decontamination to enter storm drains or watercourses. Collect and dispose of contaminated water in accordance with WM-io, Liquid Waste Management. • Contain water overflow or minor water spillage and do not allow it to discharge into drainage facilities or watercourses. • Place proper storage, cleanup, and spill reporting instructions for hazardous materials stored or used on the project site in an open, conspicuous, and accessible location. • Keep waste storage areas clean, well organized, and equipped with ample cleanup supplies as appropriate for the materials being stored. Perimeter controls, containment structures, covers, and liners should be repaired or replaced as needed to maintain proper function. Cleanup • Clean up leaks and spills immediately. • Use a rag for small spills on paved surfaces, a damp mop for general cleanup, and absorbent material for larger spills. If the spDled material is hazardous, then the used cleanup materials are also hazardous and must be sent to either a certified laundry (rags) or disposed of as hazardous waste. • Never hose down or bury dry material spills. Clean up as much of the material as possible and dispose of properly. See the waste management BMPs in this section for specific information. Minor Spills • Minor spills typically involve small quantities of oil, gasoline, paint, etc. which can be controlled by the first responder at the discovery of the spill. • Use absorbent materials on small spills rather than hosing down or burying the spill. • Absorbent materials should be promptly removed and disposed of properly. • Follow the practice below for a minor spill: Contain the spread of the spill. Recover spilled materials. Clean the contaminated area and properly dispose of contaminated materials. Semi-Significant Spills • Semi-significant spills still can be controlled by the first responder along with the aid of other personnel such as laborers and the foreman, etc. This response may require the cessation of all other activities. November 2009 California Stormwater BMP Handbook 3 of 6 Construction www.casqa.org Spill Prevention and Control WM-4 • Spills should be cleaned up immediately: Contain spread of the spill. Notify the project foreman immediately. If the spill occurs on paved or impermeable surfaces, clean up using "dry" methods (absorbent materials, cat litter and/or rags). Contain the spill by encircling with absorbent materials and do not let the spill spread widely. If the spill occurs in dirt areas, immediately contain the spill by constructing an earthen dike. Dig up and properly dispose of contaminated soil. If the spill occurs during rain, cover spill with tarps or other material to prevent contaminating runoff. Significant/Hazardous Spills • For significant or hazardous spills that cannot be controlled by personnel in the immediate vicinity, the following steps should be taken: Notify the local emergency response by dialing 911. In addition to 911, the contractor will notify the proper county officials. It is the contractor's responsibility to have all emergency phone numbers at the construction site. Notify the Governor's Office of Emergency Services Warning Center, (916) 845-8911. For spills of federal reportable quantities, in conformance with the requirements in 40 CFR parts 110,119, and 3°2» the contractor should notify the National Response Center at (800) 424-8802. Notification should first be made by telephone and followed up with a written report. The services of a spills contractor or a Haz-Mat team should be obtained immediately. Construction personnel should not attempt to clean up until the appropriate and qualified staffs have arrived at the job site. Other agencies which may need to be consulted include, but are not limited to, the Fire Department, the Public Works Department, the Coast Guard, the Highway Patrol, the City/County Police Department, Department of Toxic Substances, California Division of Oil and Gas, Cal/OSHA, etc. Reporting m Report significant spills to local agencies, such as the Fire Department; they can assist in cleanup. • Federal regulations require that any significant oil spill into a water body or onto an adjoining shoreline be reported to the National Response Center (NRC) at 800-424-8802 (24 hours). Use the following measures related to specific activities: November 2009 California Stormwater BMP Handbook 4 of 6 Construction www.casqa.org Spill Prevention and Control WM-4 Vehicle and Equipment Maintenance • If maintenance must occur onsite, use a designated area and a secondary containment, located away from drainage courses, to prevent the runon of stormwater and the runoff of spills. • Regularly inspect onsite vehicles and equipment for leaks and repair immediately • Check incoming vehicles and equipment (including delivery trucks, and employee and subcontractor vehicles) for leaking oil and fluids. Do not allow leaking vehicles or equipment onsite. • Always use secondary containment, such as a drain pan or drop cloth, to catch spills or leaks when removing or changing fluids. • Place drip pans or absorbent materials under paving equipment when not in use. • Use absorbent materials on small spills rather than hosing down or burying the spill. Remove the absorbent materials promptly and dispose of properly. • Promptly transfer used fluids to the proper waste or recycling drums. Don't leave full drip pans or other open containers lying around • Oil filters disposed of in trashcans or dumpsters can leak oil and pollute stormwater. Place the oil filter in a funnel over a waste oil-recycling drum to drain excess oil before disposal. Oil filters can also be recycled. Ask the oil supplier or recycler about recycling oil filters. • Store cracked batteries in a non-leaking secondary container. Do this with all cracked batteries even if you think all the acid has drained out. If you drop a battery, treat it as if it is cracked. Put it into the containment area until you are sure it is not leaking. Vehicle and Equipment Fueling • If fueling must occur onsite, use designate areas, located away from drainage courses, to prevent the runon of stormwater and the runoff of spills. • Discourage "topping off of fuel tanks. • Always use secondary containment, such as a drain pan, when fueling to catch spills/ leaks. Costs Prevention of leaks and spills is inexpensive. Treatment and/ or disposal of contaminated soil or water can be quite expensive. Inspection and Maintenance • Inspect and verify that activity-based BMPs are in place prior to the commencement of associated activities. While activities associated with the BMP are under way, inspect weekly during the rainy season and of two-week intervals in the non-rainy season to verify continued BMP implementation. • Inspect BMPs subject to non-stormwater discharge daily while non-stormwater discharges occur. November 2009 California Stormwater BMP Handbook 5 of 6 Construction www.casqa.org Spill Prevention and Control WM-4 • Keep ample supplies of spill control and cleanup materials onsite, near storage, unloading, and maintenance areas. • Update your spill prevention and control plan and stock cleanup materials as changes occur in the types of chemicals onsite.

Suitable Applications This BMP is suitable for construction sites where the following wastes are generated or stored: • Solid waste generated from trees and shrubs removed during land clearing, demolition of existing structures (rubble), and building construction • Packaging materials including wood, paper, and plastic • Scrap or surplus buOding materials including scrap metals, rubber, plastic, glass pieces and masonry products • Domestic wastes including food containers such as beverage cans, coffee cups, paper bags, plastic wrappers, and cigarettes • Construction wastes including brick, mortar, timber, steel and metal scraps, pipe and electrical cuttings, non- hazardous equipment parts, styrofoam and other materials used to transport and package construction materials • Highway planting wastes, including vegetative material, Categories EC SE TC WE NS WM Erosion Control Sediment Control Tracking Control Wind Erosion Control Non-Stormwater Management Control Waste Management and Materials Pollution Control El Legend: El Primary Objective IHI Secondary Objective Targeted Constituents Sediment Nutrients Trash Metals Bacteria Oil and Grease Organics 0 El El 0 0 0 Potential Alternatives None CAUFOHNUSTORMWATEg November 2009 California Stormwater BMP Handbook Construction www.casqa.org Iof4 Solid Waste Management WM-5 plant containers, and packaging materials Limitations Temporary stockpiling of certain construction wastes may not necessitate stringent drainage related controls during the non-rainy season or in desert areas with low rainfall. Implementation The following steps will help keep a clean site and reduce stormwater pollution: • Select designated waste collection areas onsite. • Inform trash-hauling contractors that you will accept only watertight dumpsters for onsite use. Inspect dumpsters for leaks and repair any dumpster that is not watertight. • Locate containers in a covered area or in a secondary containment. • Provide an adequate number of containers with lids or covers that can be placed over the container to keep rain out or to prevent loss of wastes when it is windy. • Plan for additional containers and more frequent pickup during the demolition phase of construction. • Collect site trash dairy, especially during rainy and windy conditions. • Remove this solid waste promptly since erosion and sediment control devices tend to collect litter. • Make sure that toxic liquid wastes (used oils, solvents, and paints) and chemicals (acids, pesticides, additives, curing compounds) are not disposed of in dumpsters designated for construction debris. • Do not hose out dumpsters on the construction site. Leave dumpster cleaning to the trash hauling contractor. • Arrange for regular waste collection before containers overflow. • Clean up immediately if a container does spill. • Make sure that construction waste is collected, removed, and disposed of only at authorized disposal areas. Education • Have the contractor's superintendent or representative oversee and enforce proper solid waste management procedures and practices. • Instruct employees and subcontractors on identification of solid waste and hazardous waste. • Educate employees and subcontractors on solid waste storage and disposal procedures. • Hold regular meetings to discuss and reinforce disposal procedures (incorporate into regular safety meetings). November 2009 California Stormwater BMP Handbook 2 of 4 Construction www.casqa.org Solid Waste Management WM-5 • Require that employees and subcontractors follow solid waste handling and storage procedures. • Prohibit littering by employees, subcontractors, and visitors. • Minimize production of solid waste materials wherever possible. Collection, Storage, and Disposal • Littering on the project site should be prohibited. • To prevent clogging of the storm drainage system, litter and debris removal from drainage grates, trash racks, and ditch lines should be a priority. • Trash receptacles should be provided in the contractor's yard, field trailer areas, and at locations where workers congregate for lunch and break periods. • Litter from work areas within the construction limits of the project site should be collected and placed in watertight dumpsters at least weekly, regardless of whether the litter was generated by the contractor, the public, or others. Collected litter and debris should not be placed in or next to drain inlets, stormwater drainage systems, or watercourses. • Dumpsters of sufficient size and number should be provided to contain the solid waste generated by the project. • Full dumpsters should be removed from the project site and the contents should be disposed of by the trash hauling contractor. • Construction debris and waste should be removed from the site biweekly or more frequently as needed. • Construction material visible to the public should be stored or stacked in an orderly manner. • Stormwater runon should be prevented from contacting stored solid waste through the use of berms, dikes, or other temporary diversion structures or through the use of measures to elevate waste from site surfaces. • Solid waste storage areas should be located at least 50 ft from drainage facilities and watercourses and should not be located in areas prone to flooding or ponding. • Except during fair weather, construction and highway planting waste not stored in watertight dumpsters should be securely covered from wind and rain by covering the waste with tarps or plastic. • Segregate potentially hazardous waste from non-hazardous construction site waste. • Make sure that toxic liquid wastes (used oils, solvents, and paints) and chemicals (acids, pesticides, additives, curing compounds) are not disposed of in dumpsters designated for construction debris. • For disposal of hazardous waste, see WM-6, Hazardous Waste Management. Have hazardous waste hauled to an appropriate disposal and/or recycling facility. November 2009 California Stormwater BMP Handbook 3 of 4 Construction www.casqa.org Solid Waste Management WM-5 • Salvage or recycle useful vegetation debris, packaging and surplus building materials when practical. For example, trees and shrubs from land clearing can be used as a brush barrier, or converted into wood chips, then used as mulch on graded areas. Wood pallets, cardboard boxes, and construction scraps can also be recycled. Costs All of the above are low cost measures. Inspection and Maintenance • Inspect and verify that activity-based BMPs are in place prior to the commencement of associated activities. While activities associated with the BMP are under way, inspect weekly during the rainy season and of two-week intervals in the non-rainy season to verify continued BMP implementation. • Inspect BMPs subject to non-stormwater discharge daily while non-stormwater discharges occur • Inspect construction waste area regularly. • Arrange for regular waste collection.

Suitable Applications This best management practice (BMP) applies to all construction projects. Hazardous waste management practices are implemented on construction projects that generate waste from the use of: - Petroleum Products - Concrete Curing Compounds - Palliatives - Septic Wastes - Stains - Wood Preservatives - Asphalt Products - Pesticides - Acids - Paints - Solvents - Roofing Tar - Any materials deemed a hazardous waste in California, Title 22 Division 4.5, or listed in 40 CFR Parts no, 117, 261, or 302 Categories EC Erosion Control SE Sediment Control TC Tracking Control WE Wind Erosion Control Non-Stormwater Management Control Waste Management and NS Materials Pollution Control Legend: 0 Primary Objective IH1 Secondary Objective Targeted Constituents Sediment Nutrients 0 Trash 0 Metals 0 Bacteria 0 Oil and Grease 0 Organics 0 Potential Alternatives None CALIFORNIA STOBMWATEH November 2009 California Stormwater BMP Handbook Construction www.casqa.org Iof6 Hazardous Waste Management WM-6 In addition, sites with existing structures may contain wastes, which must be disposed of in accordance with federal, state, and local regulations. These wastes include: • Sandblasting grit mixed with lead-, cadmium-, or chromium-based paints • Asbestos • PCBs (particularly in older transformers) Limitations • Hazardous waste that cannot be reused or recycled must be disposed of by a licensed hazardous waste hauler. • Nothing in this BMP relieves the contractor from responsibility for compliance with federal, state, and local laws regarding storage, handling, transportation, and disposal of hazardous wastes. • This BMP does not cover aerially deposited lead (ADL) soils. For ADL soils refer to WM-y, Contaminated Soil Management. Implementation The following steps will help reduce stormwater pollution from hazardous wastes: Material Use • Wastes should be stored in sealed containers constructed of a suitable material and should be labeled as required by Title 22 CCR, Division 4.5 and 49 CFR Parts 172,173,178, and 179. • All hazardous waste should be stored, transported, and disposed as required in Title 22 CCR, Division 4.5 and 49 CFR 261-263. • Waste containers should be stored in temporary containment facilities that should comply with the following requirements: Temporary containment facility should provide for a spill containment volume equal to 1.5 times the volume of all containers able to contain precipitation from a 25 year storm event, plus the greater of 10% of the aggregate volume of all containers or 100% of the capacity of the largest tank within its boundary, whichever is greater. Temporary containment facility should be impervious to the materials stored there for a minimum contact time of 72 hours. Temporary containment facilities should be maintained free of accumulated rainwater and spills. In the event of spills or leaks, accumulated rainwater and spills should be placed into drums after each rainfall. These liquids should be handled as a hazardous waste unless testing determines them to be non-hazardous. Non-hazardous liquids should be sent to an approved disposal site. Sufficient separation should be provided between stored containers to allow for spill cleanup and emergency response access. November 2009 California Stormwater BMP Handbook 2 of 6 Construction www.casqa.org Hazardous Waste Management WM-6 Incompatible materials, such as chlorine and ammonia, should not be stored in the same temporary containment facility. Throughout the rainy season, temporary containment facilities should be covered during non-working days, and prior to rain events. Covered facilities may include use of plastic tarps for small facilities or constructed roofs with overhangs. • Drums should not be overfilled and wastes should not be mixed. • Unless watertight, containers of dry waste should be stored on pallets. • Do not over-apply herbicides and pesticides. Prepare only the amount needed. Follow the recommended usage instructions. Over application is expensive and environmentally harmful. Apply surface dressings in several smaller applications, as opposed to one large application. Allow time for infiltration and avoid excess material being carried offsite by runoff. Do not apply these chemicals just before it rains. People applying pesticides must be certified in accordance with federal and state regulations. • Paint brushes and equipment for water and oil based paints should be cleaned within a contained area and should not be allowed to contaminate site soils, watercourses, or drainage systems. Waste paints, thinners, solvents, residues, and sludges that cannot be recycled or reused should be disposed of as hazardous waste. When thoroughly dry, latex paint and paint cans, used brushes, rags, absorbent materials, and drop cloths should be disposed of as solid waste. • Do not clean out brushes or rinse paint containers into the dirt, street, gutter, storm drain, or stream. "Paint out" brushes as much as possible. Rinse water-based paints to the sanitary sewer. Filter and reuse thinners and solvents. Dispose of excess oil-based paints and sludge as hazardous waste. • The following actions should be taken with respect to temporary contaminant: Ensure that adequate hazardous waste storage volume is available. Ensure that hazardous waste collection containers are conveniently located. Designate hazardous waste storage areas onsite away from storm drains or watercourses and away from moving vehicles and equipment to prevent accidental spills. Minimize production or generation of hazardous materials and hazardous waste on the job site. Use containment berms in fueling and maintenance areas and where the potential for spills is high. Segregate potentially hazardous waste from non-hazardous construction site debris. Keep liquid or semi-liquid hazardous waste in appropriate containers (closed drums or similar) and under cover. November 2009 California Stormwater BMP Handbook 3 of 6 Construction www.casqa.org Hazardous Waste Management WM-6 Clearly label all hazardous waste containers with the waste being stored and the date of accumulation. Place hazardous waste containers in secondary containment. Do not allow potentially hazardous waste materials to accumulate on the ground. Do not mix wastes. Use all of the product before disposing of the container. Do not remove the original product label; it contains important safety and disposal information. Waste Recycling Disposal • Select designated hazardous waste collection areas onsite. • Hazardous materials and wastes should be stored in covered containers and protected from vandalism. • Place hazardous waste containers in secondary containment. • Do not mix wastes, this can cause chemical reactions, making recycling impossible and complicating disposal. • Recycle any useful materials such as used oil or water-based paint. • Make sure that toxic liquid wastes (used oils, solvents, and paints) and chemicals (acids, pesticides, additives, curing compounds) are not disposed of in dumpsters designated for construction debris. • Arrange for regular waste collection before containers overflow. • Make sure that hazardous waste (e.g., excess oil-based paint and sludge) is collected, removed, and disposed of only at authorized disposal areas. Disposal Procedures m Waste should be disposed of by a licensed hazardous waste transporter at an authorized and licensed disposal facility or recycling facility utilizing properly completed Uniform Hazardous Waste Manifest forms. • A Department of Health Services certified laboratory should sample waste to determine the appropriate disposal facility. • Properly dispose of rainwater in secondary containment that may have mixed with hazardous waste. • Attention is directed to "Hazardous Material", "Contaminated Material", and "Aerially Deposited Lead" of the contract documents regarding the handling and disposal of hazardous materials. November 2009 California Stormwater BMP Handbook 4 of 6 Construction www.casqa.org Hazardous Waste Management WM-6 Education • Educate employees and subcontractors on hazardous waste storage and disposal procedures. • Educate employees and subcontractors on potential dangers to humans and the environment from hazardous wastes. • Instruct employees and subcontractors on safety procedures for common construction site hazardous wastes. • Instruct employees and subcontractors in identification of hazardous and solid waste. • Hold regular meetings to discuss and reinforce hazardous waste management procedures (incorporate into regular safety meetings). • The contractor's superintendent or representative should oversee and enforce proper hazardous waste management procedures and practices. • Make sure that hazardous waste is collected, removed, and disposed of only at authorized disposal areas. • Warning signs should be placed in areas recently treated with chemicals. • Place a stockpile of spill cleanup materials where it will be readily accessible. • If a container does spill, clean up immediately. Costs All of the above are low cost measures. Inspection and Maintenance m Inspect and verify that activity—based BMPs are in place prior to the commencement of associated activities. While activities associated with the BMP are under way, inspect weekly during the rainy season and of two week intervals in the non-rainy season to verify continued BMP implementation. • Inspect BMPs subject to non-stormwater discharge daily while non-stormwater discharges occur • Hazardous waste should be regularly collected. • A foreman or construction supervisor should monitor onsite hazardous waste storage and disposal procedures. • Waste storage areas should be kept clean, well organized, and equipped with ample cleanup supplies as appropriate for the materials being stored. • Perimeter controls, containment structures, covers, and liners should be repaired or replaced as needed to maintain proper function. • Hazardous spills should be cleaned up and reported in conform ance with the applicable Material Safety Data Sheet (MSDS) and the instructions posted at the project site. November 2009 California Stormwater BMP Handbook 5 of 6 Construction www.casqa.org Hazardous Waste Management WM-6 • The National Response Center, at (800) 424-8802, should be notified of spills of federal reportable quantities in conformance with the requirements in 40 CFR parts no, 117, and 302. Also notify the Governors Office of Emergency Services Warning Center at (916) 845- 8911. • A copy of the hazardous waste manifests should be provided.

November 2009 California Stormwater BMP Handbook 6 of 6 Construction www.casqa.org Concrete Waste Management WM-8 CONCRETE WASHOUT AREA Categories Description and Purpose Prevent the discharge of pollutants to stormwater from concrete waste by conducting washout onsite or offsite in a designated area, and by employee and subcontractor training. The General Permit incorporates Numeric Effluent Limits (NEL) and Numeric Action Levels (NAL) for pH (see Section 2 of this handbook to determine your project's risk level and if you are subject to these requirements). Many types of construction materials, including mortar, concrete, stucco, cement and block and their associated wastes have basic chemical properties that can raise pH levels outside of the permitted range. Additional care should be taken when managing these materials to prevent them from coming into contact with stormwater flows and raising pH to levels outside the accepted range. Suitable Applications Concrete waste management procedures and practices are implemented on construction projects where: • Concrete is used as a construction material or where concrete dust and debris result from demolition activities. • Slurries containing portland cement concrete (PCC) are generated, such as from saw cutting, coring, grinding, grooving, and hydro-concrete demolition.

Limitations • Offsite washout of concrete wastes may not always be possible. • Multiple washouts may be needed to assure adequate capacity and to allow for evaporation. Implementation The following steps will help reduce stormwater pollution from concrete wastes: • Incorporate requirements for concrete waste management into material supplier and subcontractor agreements. • Store dry and wet materials under cover, away from drainage areas. Refer to WM-i, Material Delivery and Storage for more information. • Avoid mixing excess amounts of concrete. • Perform washout of concrete trucks in designated areas only, where washout will not reach stormwater. • Do not wash out concrete trucks into storm drains, open ditches, streets, streams or onto the ground. Trucks should always be washed out into designated facilities. • Do not allow excess concrete to be dumped onsite, except in designated areas. • For onsite washout: On larger sites, it is recommended to locate washout areas at least 50 feet from storm drains, open ditches, or water bodies. Do not allow runoff from this area by constructing a temporary pit or bermed area large enough for liquid and solid waste. Washout wastes into the temporary washout where the concrete can set, be broken up, and then disposed properly. Washout should be lined so there is no discharge into the underlying soil. • Do not wash sweepings from exposed aggregate concrete into the street or storm drain. Collect and return sweepings to aggregate base stockpile or dispose in the trash. • See typical concrete washout installation details at the end of this fact sheet. Education • Educate employees, subcontractors, and suppliers on the concrete waste management techniques described herein. November 2009 California Stormwater BMP Handbook 2 of 7 Construction www.casqa.org Concrete Waste Management WM-8 • Arrange for contractor's superintendent or representative to oversee and enforce concrete waste management procedures. • Discuss the concrete management techniques described in this BMP (such as handling of concrete waste and washout) with the ready-mix concrete supplier before any deliveries are made. Concrete Demolition Wastes • Stockpile concrete demolition waste in accordance with BMP WM-3, Stockpile Management. • Dispose of or recycle hardened concrete waste hi accordance with applicable federal, state or local regulations. Concrete Slurry Wastes • PCC and AC waste should not be allowed to enter storm drains or watercourses. • PCC and AC waste should be collected and disposed of or placed in a temporary concrete washout facility (as described in Onsite Temporary Concrete Washout Facility, Concrete Transit Truck Washout Procedures, below). • A foreman or construction supervisor should monitor onsite concrete working tasks, such as saw cutting, coring, grinding and grooving to ensure proper methods are implemented. • Saw-cut concrete slurry should not be allowed to enter storm drains or watercourses. Residue from grinding operations should be picked up by means of a vacuum attachment to the grinding machine or by sweeping. Saw cutting residue should not be allowed to flow across the pavement and should not be left on the surface of the pavement. See also NS-3, Paving and Grinding Operations; and WM-io, Liquid Waste Management. • Concrete slurry residue should be disposed in a temporary washout facility (as described in Onsite Temporary Concrete Washout Facility, Concrete Transit Truck Washout Procedures, below) and allowed to dry. Dispose of dry slurry residue in accordance with WM-5, Solid Waste Management. Onsite Temporary Concrete Washout Facility, Transit Truck Washout Procedures m Temporary concrete washout facilities should be located a minimum of 50 ft from storm drain inlets, open drainage facilities, and watercourses. Each facility should be located away from construction traffic or access areas to prevent disturbance or tracking. • A sign should be installed adjacent to each washout facility to inform concrete equipment operators to utilize the proper facilities. • Temporary concrete washout facilities should be constructed above grade or below grade at the option of the contractor. Temporary concrete washout facilities should be constructed and maintained in sufficient quantity and size to contain all liquid and concrete waste generated by washout operations. November 2009 California Stormwater BMP Handbook 3 of 7 Construction www.casqa.org Concrete Waste Management WM-8 • Temporary washout facilities should have a temporary pit or bermed areas of sufficient volume to completely contain all liquid and waste concrete materials generated during washout procedures. • Temporary washout facilities should be lined to prevent discharge to the underlying ground or surrounding area. • Washout of concrete trucks should be performed in designated areas only. • Only concrete from mixer truck chutes should be washed into concrete wash out. • Concrete washout from concrete pumper bins can be washed into concrete pumper trucks and discharged into designated washout area or properly disposed of or recycled offsite. • Once concrete wastes are washed into the designated area and allowed to harden, the concrete should be broken up, removed, and disposed of per WM-5, Solid Waste Management. Dispose of or recycle hardened concrete on a regular basis. • Temporary Concrete Washout Facility (Type Above Grade) Temporary concrete washout facility (type above grade) should be constructed as shown on the details at the end of this BMP, with a recommended minimum length and minimum width of 10 ft; however, smaller sites or jobs may only need a smaller washout facility. With any washout, always maintain a sufficient quantity and volume to contain all liquid and concrete waste generated by washout operations. Materials used to construct the washout area should conform to the provisions detailed in their respective BMPs (e.g., SE-8 Sandbag Barrier). Plastic lining material should be a minimum of 10 mil in polyethylene sheeting and should be free of holes, tears, or other defects that compromise the impermeability of the material. Alternatively, portable removable containers can be used as above grade concrete washouts. Also called a "roll-off"; this concrete washout facility should be properly sealed to prevent leakage, and should be removed from the site and replaced when the container reaches 75% capacity. • Temporary Concrete Washout Facility (Type Below Grade) Temporary concrete washout facilities (type below grade) should be constructed as shown on the details at the end of this BMP, with a recommended minimum length and minimum width of 10 ft. The quantity and volume should be sufficient to contain all liquid and concrete waste generated by washout operations. Lath and flagging should be commercial type. Plastic lining material should be a minimum of 10 mil polyethylene sheeting and should be free of holes, tears, or other defects that compromise the impermeability of the material. November 2009 California Stormwater BMP Handbook 4 of 7 Construction www.casqa.org Concrete Waste Management WM-8 - The base of a washout facility should be free of rock or debris that may damage a plastic liner. Removal of Temporary Concrete Washout Facilities • When temporary concrete washout facilities are no longer required for the work, the hardened concrete should be removed and properly disposed or recycled in accordance with federal, state or local regulations. Materials used to construct temporary concrete washout facilities should be removed from the site of the work and properly disposed or recycled in accordance with federal, state or local regulations.. • Holes, depressions or other ground disturbance caused by the removal of the temporary concrete washout facilities should be backfilled and repaired. Costs All of the above are low cost measures. Roll-off concrete washout facilities can be more costly than other measures due to removal and replacement; however, provide a cleaner alternative to traditional washouts. The type of washout facility, size, and availability of materials will determine the cost of the washout. Inspection and Maintenance • BMPs must be inspected in accordance with General Permit requirements for the associated project type and risk level. It is recommended that at a minimum, BMPs be inspected weekly, prior to forecasted rain events, daily during extended rain events, and after the conclusion of rain events. • Temporary concrete washout facilities should be maintained to provide adequate holding capacity with a minimum freeboard of 4 in. for above grade facilities and 12 in. for below grade facilities. Maintaining temporary concrete washout facilities should include removing and disposing of hardened concrete and returning the facilities to a functional condition. Hardened concrete materials should be removed and properly disposed or recycled in accordance with federal, state or local regulations. • Washout facilities must be cleaned, or new facilities must be constructed and ready for use once the washout is 75% full. • Inspect washout facilities for damage (e.g. torn liner, evidence of leaks, signage, etc.). Repair all identified damage.

Categories Description and Purpose Proper sanitary and septic waste management prevent the discharge of pollutants to stormwater from sanitary and septic waste by providing convenient, well-maintained facilities, and arranging for regular service and disposal. Suitable Applications Sanitary septic waste management practices are suitable for use at all construction sites that use temporary or portable sanitary and septic waste systems. Limitations None identified. Implementation Sanitary or septic wastes should be treated or disposed of in accordance with state and local requirements. In many cases, one contract with a local facility supplier will be all that it takes to make sure sanitary wastes are properly disposed. Storage and Disposal Procedures m Temporary sanitary facilities should be located away from drainage facilities, watercourses, and from traffic circulation. If site conditions allow, place portable facilities a minimum of 50 feet from drainage conveyances and traffic areas. When subjected to high winds or risk of high winds, temporary sanitary facilities should be secured to prevent overturning.

Education • Educate employees, subcontractors, and suppliers on sanitary and septic waste storage and disposal procedures. • Educate employees, subcontractors, and suppliers of potential dangers to humans and the environment from sanitary and septic wastes. • Instruct employees, subcontractors, and suppliers in identification of sanitary and septic waste. • Hold regular meetings to discuss and reinforce the use of sanitary facilities (incorporate into regular safety meetings). • Establish a continuing education program to indoctrinate new employees. Costs All of the above are low cost measures. November 2009 California Stormwater BMP Handbook 2 of 3 Construction www.casqa.org Sanitary/Septic Waste Management WM-9 Inspection and Maintenance • BMPs must be inspected in accordance with General Permit requirements for the associated project type and risk level. It is recommended that at a minimum, BMPs be inspected weekly, prior to forecasted rain events, daily during extended rain events, and after the conclusion of rain events. • Arrange for regular waste collection. • If high winds are expected, portable sanitary facilities must be secured with spikes or weighed down to prevent over turning. • If spills or leaks from sanitary or septic facilities occur that are not contained and discharge from the site, non-visible sampling of site discharge maybe required. Refer to the General Permit or to your project specific Construction Site Monitoring Plan to determine if and where sampling is required.

November 2009 California Stormwater BMP Handbook 3 of 3 Construction www.casqa.org Liquid Waste Management WM-10 Description and Purpose Liquid waste management includes procedures and practices to prevent discharge of pollutants to the storm drain system or to watercourses as a result of the creation, collection, and disposal of non-hazardous liquid wastes. Suitable Applications Liquid waste management is applicable to construction projects that generate any of the following non-hazardous by-products, residuals, or wastes: • Drilling slurries and drilling fluids • Grease-free and oil-free wastewater and rinse water • Dredgings » Other non-stormwater liquid discharges not permitted by separate permits Limitations • Disposal of some liquid wastes may be subject to specific laws and regulations or to requirements of other permits secured for the construction project (e.g., NPDES permits, Army Corps permits, Coastal Commission permits, etc.). • Liquid waste management does not apply to dewatering operations (NS-2 Dewatering Operations), solid waste management (WM-5, Solid Waste Management), hazardous wastes (WM-6, Hazardous Waste Management), or concrete slurry residue (WM-8, Concrete Waste Categories EC SE TC WE NS WM Erosion Control Sediment Control Tracking Control Wind Erosbn Control Non-Stormwater Management Control Waste Management and Materials Pollution Control El Legend: El Primary Objective IH1 Secondary Objective Targeted Constituents Sediment El Nutrients 0 Trash B Metals El Bacteria Oil and Grease Ef Organics Potential Alternatives None CALIFORNIA STOKMWATCR November 2009 California Stormwater BMP Handbook Construction www.casqa.org Iof4 Liquid Waste Management WM-10 Management). • Typical permitted non-stormwater discharges can include: water line flushing; landscape irrigation; diverted stream flows; rising ground waters; uncontaminated pumped ground water; discharges from potable water sources; foundation drains; irrigation water; springs; water from crawl space pumps; footing drains; lawn watering; flows from riparian habitats and wetlands; and discharges or flows from emergency fire fighting activities. Implementation General Practices m Instruct employees and subcontractors how to safely differentiate between non-hazardous liquid waste and potential or known hazardous liquid waste. • Instruct employees, subcontractors, and suppliers that it is unacceptable for any liquid waste to enter any storm drainage device, waterway, or receiving water. • Educate employees and subcontractors on liquid waste generating activities and liquid waste storage and disposal procedures. • Hold regular meetings to discuss and reinforce disposal procedures (incorporate into regular safety meetings). • Verify which non-stormwater discharges are permitted by the statewide NPDES permit; different regions might have different requirements not outlined in this permit. • Apply NS-8, Vehicle and Equipment Cleaning for managing wash water and rinse water from vehicle and equipment cleaning operations. Containing Liquid Wastes • Drilling residue and drilling fluids should not be allowed to enter storm drains and watercourses and should be disposed of. • If an appropriate location is available, drilling residue and drilling fluids that are exempt under Title 23, CCR § 25ii(g) may be dried by infiltration and evaporation in a containment facility constructed in conformance with the provisions concerning the Temporary Concrete Washout Facilities detailed in WM-8, Concrete Waste Management. • Liquid wastes generated as part of an operational procedure, such as water-laden dredged material and drilling mud, should be contained and not allowed to flow into drainage channels or receiving waters prior to treatment. • Liquid wastes should be contained in a controlled area such as a holding pit, sediment basin, roll-off bin, or portable tank. • Containment devices must be structurally sound and leak free. • Containment devices must be of sufficient quantity or volume to completely contain the liquid wastes generated. November 2009 California Stormwater BMP Handbook 2 of 4 Construction www.casqa.org Liquid Waste Management WM-10 • Precautions should be taken to avoid spills or accidental releases of contained liquid wastes. Apply the education measures and spill response procedures outlined in WM-4, Spill Prevention and Control. • Containment areas or devices should not be located where accidental release of the contained liquid can threaten health or safety or discharge to water bodies, channels, or storm drains. Capturing Liquid Wastes • Capture all liquid wastes that have the potential to affect the storm drainage system (such as wash water and rinse water from cleaning walls or pavement), before they run off a surface. • Do not allow liquid wastes to flow or discharge uncontrolled. Use temporary dikes or berms to intercept flows and direct them to a containment area or device for capture. • Use a sediment trap (SE-3, Sediment Trap) for capturing and treating sediment laden liquid waste or capture in a containment device and allow sediment to settle. Disposing of Liquid Wastes • A typical method to handle liquid waste is to dewater the contained liquid waste, using procedures such as described in NS-2, Dewatering Operations, and SE-2, Sediment Basin, and dispose of resulting solids per WM-5, Solid Waste Management. • Methods of disposal for some liquid wastes may be prescribed in Water Quality Reports, NPDES permits, Environmental Impact Reports, 401 or 404 permits, and local agency discharge permits, etc. Review the SWPPP to see if disposal methods are identified. • Liquid wastes, such as from dredged material, may require testing and certification whether it is hazardous or not before a disposal method can be determined. • For disposal of hazardous waste, see WM-6, Hazardous Waste Management. • If necessary, further treat liquid wastes prior to disposal. Treatment may include, though is not limited to, sedimentation, filtration, and chemical neutralization. Costs Prevention costs for liquid waste management are minimal. Costs increase if cleanup or fines are involved. Inspection and Maintenance • Inspect and verify that activity-based BMPs are in place prior to the commencement of associated activities. While activities associated with the BMP are under way, inspect weekly during the rainy season and of two-week intervals in the non-rainy season to verify continued BMP implementation. • Inspect BMPs subject to non-stormwater discharge daily while non-stormwater discharges occur. November 2009 California Stormwater BMP Handbook 3 of 4 Construction www.casqa.org Liquid Waste Management WM-10 • Remove deposited solids in containment areas and capturing devices as needed and at the completion of the task. Dispose of any solids as described in WM-5, Solid Waste Management. • Inspect containment areas and capturing devices and repair as needed.

Attached is a completed form for the Calavera Hills Sewer Treatment Plant Demolition project. It does not meet the Priority Development Project (POP) requirements since it is not a "significant redevelopment" and it does not meet any of the "new developmenf criteria in Section 1 of the SWSQ (this is not a "Pollutant-generating Development Projecf). Since it is not a POP, this project must only comply with the Standard Stormwater Requirements per the SUSMP. This includes the applicable guidelines in Section 1 as well as implementation of applicable source control BMPs listed in Appendix 1 (in the case of this project, none of the source control BMPs listed in Appendix 1 are applicable). Pollutant generation from the site will be greatly reduced since the existing facility is being demolished and then graded as a relatively flat pad with non-irrigated non-invasive vegetation. The amount of impervious surfaces on the site will be reduced from 2.4 acres to only 0.02 acres (concrete pad at the west side). The limited remaining impervious area will disconnected from the storm drain system. There is a small natural area in the south end of the site that will be conserved. Based on the information above, I believe this project is in compliance with the City SUSMP requirements. Please feel free to contact me by phone at (858) 614-5000 if you have any questions about the findings of this memorandum.

Initially this questionnaire must be completed by the applicant in advance of submitting for a development application (subdivision, discretionary permits and/or construction permits). The results of the questionnaire determine the level of storm water standards that must be applied to a proposed development or redevelopment project. Depending on the outcome, your project will either be subject to 'Standard Stormwater Requirements' or be subject additional criteria called 'Priority Development Project Requirements'. Many aspects of project site design are dependent upon the storm water standards applied to a project. Applicant responses to the questionnaire represent an initial assessment of the proposed project conditions and impacts. City staff has responsibility for making the final assessment after submission of the development application. If staff determines that the questionnaire was incorrectly filled out and is subject to more stringent storm water standards than initially assessed by the applicant, this will result in the return of the development application as incomplete. In this case, please make the changes to the questionnaire and resubmit to the City. If applicants are unsure about the meaning of a question or need help in determining how to respond to one or more of the questions, they are advised to seek assistance from Land Development Engineering staff. A separate completed and signed questionnaire must be submitted for each new development application submission. Only one completed and signed questionnaire is required when multiple development applications for the same project are submitted concurrently. In addition to this questionnaire, applicants for construction permits must also complete, sign and submit a Project Threat Assessment Form to address construction aspects of the project. Please answer the questions below, follow the instructions and sign the form at the end. 1. Is your project a significant redevelopment? DEFINITION: Significant redevelopment is defined as the creation, addition or replacement of at least 5,000 square feet of impervious surface on an already existing developed site. Significant redevelopment includes, but is not limited to: the expansion of a building footprint; addition to or replacement of a structure; structural development including an increase in gross floor area and/or exterior construction remodeling; replacement of an impervious surface that is not part of a routine maintenance activity; and land disturbing activities related with structural or impervious surfaces. Replacement of impervious surfaces includes any activity that is not part of a routine maintenance activity where impervious material(s) are removed, exposing underlying soil during construction. If your project IS considered significant redevelopment, then please skip Section 1 and proceed with Section 2. If your project IS NOT considered significant redevelopment, then please proceed to Section 1.

Car dealerships and similar may rinse cars with water only. See Fact Sheet SC-21, "Vehicle and Equipment Cleaning," in the CASQA Stormwater Quality Handbooks at www.cabmphandbooks.com Page 5 of 9 K. Vehicle/Equipment Repair and Maintenance Accommodate all vehicle equipment repair and maintenance indoors. Or designate an outdoor work area and design the area to prevent run-on and runoff of stormwater. Show secondary containment for exterior work areas where motor oil, brake fluid, gasoline, diesel fuel, radiator fluid, acid- containing batteries or other hazardous materials or hazardous wastes are used or stored. Drains shall not be installed within the secondary containment areas. Add a note on the plans that states either (1) there are no floor drains, or (2) floor drains are connected to wastewater pretreatment systems prior to discharge to the sanitary sewer and an industrial waste discharge permit will be obtained. Q State that no vehicle repair or maintenance will be done outdoors, or else describe the required features of the outdoor work area. Q State that there are no floor drains or if there are floor drains, note the agency from which an industrial waste discharge permit will be obtained and that the design meets that agency's requirements. ^ State that there are no tanks, containers or sinks to be used for parts cleaning or rinsing or, if there are, note the agency from which an industrial waste discharge permit will be obtained and that the design meets that agency's requirements. In the SUSMP report, note that all of the following restrictions apply to use the site: Q No person shall dispose of, nor permit the disposal, directly or indirectly of vehicle fluids, hazardous materials, or rinsewater from parts cleaning into storm drains, No vehicle fluid removal shall be performed outside a building, nor on asphalt or ground surfaces, whether inside or outside a building, except in such a manner as to ensure that any spilled fluid will be in an area of secondary containment. Leaking vehicle fluids shall be contained or drained from the vehicle immediately. No person shall leave unattended drip parts or other open containers containing vehicle fluid, unless such containers are in use or in an area of secondary containment. Page 6 of 9 L. Fuel Dispensing Areas Fueling areas1 shall have impermeable floors (i.e., portland cement concrete or equivalent smooth impervious surface) that are: a) graded at the minimum slope necessary to prevent ponding; and b) separated from the rest of the site by a grade break that prevents run-on of stormwater to the maximum extent practicable. Fueling areas shall be covered by a canopy that extends a minimum of ten feet in each direction from each pump. [Alternative: The fueling area must be covered and the cover's minimum dimensions must be equal to or greater than the area within the grade break or fuel dispensing area1.] The canopy [or cover] shall not drain onto the fueling area. Q The property owner shall dry sweep the fueling area routinely. Q See the Business Guide Sheet, "Automotive Service—Service Stations" in the CASQA Stormwater Quality Handbooks at www.cabmphandbooks.com 1 The fueling area shall be defined as the area extending a minimum of 6.5 feet from the corner of each fuel dispenser or the length at which the hose and nozzle assembly may be operated plus a minimum of one foot, whichever is greater. Page 7 of 9 M. Loading Docks Show a preliminary design for the loading dock area, including roofing and drainage. Loading docks shall be covered and/or graded to minimize run-on to and runoff from the loading area. Roof downspouts shall be positioned to direct stormwater away from the loading area. Water from loading dock areas should be drained to the sanitary sewer where feasible. Direct connections to storm drains from depressed loading docks are prohibited. Loading dock areas draining directly to the sanitary sewer shall be equipped with a spill control valve or equivalent device, which shall be kept closed during periods of operation. Provide a roof overhang over the loading area or install door skirts (cowling) at each bay that enclose the end of the trailer. Q Move loaded and unloaded items indoors as soon as possible. Q See Fact Sheet SC-30, "Outdoor Loading and Unloading," in the CASQA Stormwater Quality Handbooks at www.cabmphandbooks.com N. Fire Sprinkler Test Water Q Provide a means to drain fire sprinkler test water to the sanitary sewer. Q See the note in Fact Sheet SC-41, "Building and Grounds Maintenance," in the CASQA Stormwater Quality Handbooks at www.cabmphandbooks.com Page 8 of 9 O. Miscellaneous Drain r Wash Wateror 1 Boiler drain lines 1 Condensate drain lines '-' Rooftop equipment Drainage sumps Roofing, gutters, and trim. Q Boiler drain lines shall be directly or indirectly connected to the sanitary sewer system and may not discharge to the storm drain system. Q Condensate drain lines may discharge to landscaped areas if the flow is small enough that runoff will not occur. Condensate drain lines may not discharge to the storm drain system. Rooftop mounted equipment with Q potential to produce pollutants shall be roofed and/or have secondary containment. Any drainage sumps on-site shall Q feature a sediment sump to reduce the quantity of sediment in pumped water. Q Avoid roofing, gutters, and trim made of copper or other unprotected metals that may leach into runoff. Q P. Plazas, sidewalks, and parking lots. Plazas, sidewalks, and parking lots shall be swept regularly to prevent the accumulation of litter and debris. Debris from pressure washing shall be collected to prevent entry into the storm drain system. Washwater containing any cleaning agent or degreaser shall be collected and discharged to the sanitary sewer and not discharged to a storm drain. Page 9 of 9
