COMPLIANCE NOTIFICATION. AND LIMITATIONS The purpose of this guidance document is to assist dischargers subject to the Construction Activity Storm Water Discharge Permit, Order 99-08-DWQ, (General Permit) in implemenfing the General Permit and Resolufion 2001-046 (Testing Requirements). Users of this document are fully responsible for determining its suitability. Dischargers are fully responsible for compliance with the permit as amended. Compliance determinations are made by the Co-permittees to the San Diego Municipal Storm Water Permit, Order 2001-01 (Municipal Permit), the San Diego Regional Water Quality Control Board, the State Water Resources Control Board, and the U.S. Environmental Protecfion Agency. Dischargers who have quesfions about specific requirements of the General Permit as amended, or this guidance document are advised to consult with their legal counsel. Failure to comply with the General Permit as amended can result in significant administrafive, civil, and criminal penalfies. Users of this document shall note the following limitations on its use: The scope of this document is limited to providing guidance on the General Permit and does not address all of the requirements of local storm water ordinances or the Municipal Permit. This document does not address subsequent Resolufions and Orders issued by the State Board and Orders or policies issued by Regional Boards. The purpose of this document is to provide general informafion to assist dischargers through the process of developing a Storm Water Pollution Prevention Plan (SWPPP). This document does not consider every possible situation that may expose pollutants to storm water on a construction site. Dischargers must consider the full range of exposure of materials on their construction sites and develop appropriate strategies. SWPPPs, including sampling and analysis strategies, must be site specific for each individual project. Users need to adapt this document to each project individually. Regulatory interpretations may change over time because of new information, new court cases, or new laws. Users should consult with their legal counsel for current interpretations. NPDES regulafions govern the SWPPP requirements in the General Permit. Users should be aware that these regulations and State regulations implemenfing the NPDES program contain significant requirements regarding Prepared By: Di ' H:\SWPPP\2470-O2\Maiii Hunsaker & Associates San Diego, Inc. STORM WATER POLLUTION PREVENTION PLAN La Suvera CDP 04-16 quality assurance, quality control, qualificafions of trainers, inspectors and analytical laboratories, etc. that may not be explicitly addressed by this document. Users should consult the NPDES regulafions, or their legal counsef to determine any additional requirements. Compliance with this guidance document does not automafically equate to compliance with the General Permit. Further, modifying a site specific SWPPP to include or exclude items described in this guidance document does not necessarily mean that the site specific strategy is out of compliance the General Permit.

Background In 1972, the Federal Water Pollution Control Act (also referred to as the Clean Water Act (CWA) was amended to provide that the discharge of pollutants to waters of the United States from any point source is unlawful, unless the discharge is in compliance with a Nafional Pollutant Discharge Elimination System (NPDES) Permit. The 1987 amendments to the CWA added Section 402(p), which established a framework for regulafing municipal and industrial storm water discharges under the NPDES program. On November 16, 1990, the U. S. Environmental Protection Agency (EPA) published final regulafions that establish requirements for applications for storm water permits for specified categories of industries. The regulations provide that discharges of storm water to waters of the United States from construction projects that encompass five (5) or more acres of the soil disturbance are effectively prohibited unless the discharge is in compliance with an NPDES permit. Regulafions (Phase II Rule) that became final on December 8, 1999 expanded the exisfing NPDES program to address storm water discharges from construction sites that disturb land equal to or greater than one (1) acre and less than five (5) acres (small construction activity). The regulations require that small construcfion activity, other than those regulated under an individual or Regional Water Quality Control Board General Permit, must be permitted no later than March 10, 2003. On August 19, 1999, the State Water Resources Control Board (SWRCB) reissued the General Construction Storm Water Permit (Water Quality Order 99-08-DWQ referred to as "General Permit"). The San Francisco BayKeeper, Santa Monica BayKeeper, San Diego BayKeeper, and Orange Coast Keeper filed a petition for writ of mandate challenging the General Permit in the Superior Court, County of Sacramento. The Court issued a judgment and writ of mandate on September 15, 2000. The Court directed the SWRCB to modify the provisions ofthe General Permit to require permittees to implement specific sampling and analytical procedures to determine whether Best Management Pracfices (BMPs) implemented on a construcfion site are: (1) prevenfing further impairment by sediment in storm waters discharged directly into Prepared By: Hunsaker & Associates San Diego. Inc. H:\SWPPP\2470/002\Main STORM WATER POLLUTION PREVENTION PLAN La Suvera CDP 04-16 waters listed as impaired for sediment or silt, and (2) preventing other pollutants, that are know or should be know by permittees to occur on construction sites and that are not visually detectable in storm water discharges, from causing or contributing to Exceedances of water quality objectives. The monitoring provisions in the General Permit have been modified pursuant to the court order. The Project Storm Water Sampling and Analysis Strategy (SWSAS) are located in Appendix J. Regulated Activities Construction activity subject to the General Permit includes clearing, grading, and disturbances to the ground such as stockpiling, or excavation that results in the soil disturbance of at least one acre of total land area. Construction activity that results in soil disturbances of less than one acre is subject to this General Permit if the construction activity is part of a larger common plan of development that encompasses one or more acres of soil disturbance or if there is significant water quality impairment resulting from the activity. Disturbance can result from removing vegetative cover and exposing soils, or by placing mined or dredged material on top of the existing ground. Activities that are not defined as construction activities for purposes of this permit include: • Roufine maintenance to maintain original line and grade, hydraulic capacity, or original purpose of the facility, • Emergency construction activities required to protect public health and safety. • Dredging and/or fill discharge to any jurisdicfional surface (e.g., wetland, channel, pond or marine water), which is subject to regulafion by the U.S. Army Corps of Engineers pursuant to Section 10 of the Rivers and Harbors Act and \or Section 404 of the CWA and Section 401 Water Quality Certificate from the RWQCB/SWRCB. Notification It is the responsibility of the landowner to obtain coverage under this General Permit prior to commencement of construction activities. To obtain coverage, the landowner must file an NOI with a vicinity map and the appropriate fee with the SWRCB. In addifion, coverage under this permit shall not occur unfil the applicant develops an adequate SWPPP for the project. Section A of the General Permit oufiines the required contents of a SWPPP. PreparedBy: Hunsaker & Associates San Diego, Inc. H:\SWPPP\2470/002\Main STORM WATER POLLUTION PREVENTION PLAN La Suvera CDP 04-16 For proposed construction activity on easements or on nearby property by agreement or permission, the entity responsible for the construcfion activity shall file an NOI and filing fee and shall be responsible for development of the SWPPP, all of which must occur prior to commencement of construction activities. Goals of SWPPP This SWPPP has been prepared in accordance with the State Water Resources Control Board (SWRCB) Order No. 99-08-DWQ Nafional Pollutant Discharge Elimination System (NPDES) General Permit No. CAS000002 which was adopted on August 19, 1999 and is intended to be a living document. Its intent is to guide the property owner and contractors through compliance with the California general permit for construction activities. Parties responsible for compliance should read the general permit, included as Appendix N. The major objectives of the SWPPP are to: • Identify all pollutant sources including sources of sediment that may affect the quality of storm water discharges associated with construction activity (storm water discharges) from the construction site, and • Identify non-storm water discharges, and • Identify, construct, implement in accordance with a fime schedule, and maintain Best Management Pracfices (BMPs) to reduce or eliminate pollutants in storm water discharges and authorized non-storm water discharges from the construction site during construcfion, and • Develop a maintenance schedule for BMPs installed during construcfion designed to reduce or eliminate pollutants after construction is completed (post-construction BMPs). • Identify a sampling and analysis strategy and sampling schedule for discharges from construction activity which discharge directly into water bodies listed on Attachment 3. (Clean Water Act Section 303(d) [303(d)] Water Bodies listed for Sedimentafion). • For all construcfion activity, identify a sampling and analysis strategy and sampling schedule for discharges that have been discovered through visual monitoring to be potenfially contaminated by pollutants not visually detectable in the runoff. PreparedBy: Hunsaker & Associates San Diego, Inc. H:\SWPPP\2470/002\Main STORM WATER POLLUTION PREVENTION PLAN La Suvera CDP 04-16 Construction Activity Site condifions during construcfion change daily. This SWPPP presents information for the following phases of the construction acfivity as well as pre- and post-construction activity and they are as follows: 1) Rough Grading/Improvements, 2) Precise Grading/Finished Lots, 3) Post-Construction BMPs. The Rough Grading/Improvements phase is completed when all water, sewer and utilities are installed and streets are paved. The Precise Grading/Finished Lots phase is completed when all structures are built. The Project Information Site Map (SWPPP Wall Map) (E-5) shows the project site before construction activity begins with proposed and existing topography. The Post- Construcfion BMP exhibit (Exhibit SI, located in Appendix S) shows the BMPs proposed for the project after construction is completed. This creates obligation for the owner or their authorized representative to document the transitional stages of construction from the above mentioned milestones. Implementation of SWPPP This SWPPP will be implemented concurrently with commencement of soil-disturbing activities associated with new construcfion or immediately for ongoing construction. The requirements of the General Permit are intended to be implemented on a year-round basis. As stated on the Nofice of Intent (NOI), all condifions of the General Permit will be complied with. A copy of the General Permit is included with this SWPPP. Access to SWPPP This SWPPP, together with all monitoring information, reports and data records for this construction activity, shall remain on the construction site while the site is under construcfion and during working hours, commencing with the inifial construction activity and ending with terminafion of coverage under the General Permit. Prepared By: Hunsaker & Associates San Diego, Inc. H:\SWPPP\2470/002\Main STORM WATER POLLUTION PREVENTION PLAN La Suvera CDP 04-16 Modification Of SWPPP This SWPPP shall be amended whenever there is a change in construction or operations, which may affect the discharge of pollutants to surface waters, ground waters or a municipal separate storm sewer system (MS4). The SWPPP shall also be amended if the discharger violates any condifion of this General Permit or has not achieved the general objective of reducing or eliminating pollutants in storm water discharges. If the RWQCB determines that the discharger is in violafion of the General Permit, the SWPPP shall be amended and implemented in a fimely manner, but in no case more than 14 calendar days after notification by the RWQCB. All amendments should be dated and directly attached to the SWPPP. The RWQCB or local agency, with the concurrence of the RWQCB, may require the discharger to amend the SWPPP. The owner is responsible to amend, document and date any erosion and sediment control activities on the attached plans and this document as appropriate. This SWPPP provides recommendations and procedures to fulfill storm water discharge requirements specified by various federal, state and local authorifies. Site informafion, descripfion, and responsible parties are provided within. If a change of ownership occurs, the new owner shall be informed of the provisions of the General Permit and provided with a copy of this SWPPP. The new owner shall amend this exisfing SWPPP, if necessary, or develop a new SWPPP within 45 calendar days. Retention of Records The discharger is required to retain records of all monitoring information, copies of all reports required by the General Permit, and records of all data used to complete the NOI for all construction activities to be covered by the General Permit for a period of at least three years from the date generated. This period may be extended by request of the SWRCB and/or RWQCB. With the exception of reporting noncompliance to the appropriate RWQCB, dischargers are not required to submit the records, except upon specific request by the RWQCB. Private citizens may also obtain these records pursuant to Secfion A. 15 ofthe General Construcfion Permit or through appropriate discovery tools in litigafion.

(Post-constmction BMPs consist of permanent features designed to minimize pollutant discharges, including sediment, from the site after constmction has been completed.) Also, describe the agency or parties to be the responsible party for long-term maintenance of these BMPs. For the locafion of post-construcfion BMPs, see the Wall Map for La Suvera (Exhibit E5) located at the jobsite and Post-Construcfion Exhibit in Appendix S. For a descripfion of post-construction BMPs, see Appendix S. For a further discussion of post-construcfion BMPs, sizing, maintenance responsibility and funding, see Storm Water Management Plan (SWMP) prepared by Hunsaker & Associates San Diego, Inc. The purpose of the SWMP is to address the water quality impacts resulting from the development of the La Suvera project. The proposed project design has incorporated post-construction BMPs in order to satisfy all requirements detailed in the City of Carlsbad's "Standard Urban Storm Water Mifigafion Plan (SUSMP), and describes how the project will comply with these regulafions. All calculafions are consistent with criteria set forth by the Regional Water Quality Control Board's Order No. 2001-01, and the City of Carlsbad Storm Water Standards. Three (3) flow-based curb inlet fliter BMPs will be placed at the three receiving storm drain inlets within the La Suvera site. The 85*^ percenfile runoff will be treated in the proposed FloGard (or an equivalent approved curb inlet filter treatment unit) curb inlet filter units prior to discharging from the site. Educafion of homeowners is an important way to help reduce pollutants in the post- construcfion project. Currently in San Diego County, there is a public outreach program in place called "Think Blue." The "Think Blue" program's goal is to educate the public regarding storm water pollufion. The owner will be responsible to obtain and disseminate this informafion. Informafion regarding the "Think Blue" program can be obtained by dialing 1-888-THINK BLUE or 1-888-844-6525. Sample Homeowners informafion package can be found in Appendix O. The owner shall provide labeling/stenciling (or other approved method) of all inlets/catch basins. The owner will be responsible to obtain information regarding the jurisdicfionally approved method for labeling. The responsible party for long-term maintenance of the above-described post- construcfion BMPs is the Homeowner's Associafion.

PreparedBy: Hunsaker & 19 H:\SWPPP\2470/002\Main Associates San Diego, Inc. STORM WATER POLLUTION PREVENTION PLAN La Suvera CDP 04-16 Nutrients Inorganic substances, such as nitrogen and phosphorous, that commonly exist in the form of mineral salts that are either dissolved or suspended in water. Primary sources of nutrients in urban runoff are fertilizers and eroded soils. Excessive discharge of nutrients to water bodies and streams can cause excessive aquatic algae and plant growth. Such excessive production, referred to as cultural eutrophication, may lead to excessive decay of organic matter in the water body, loss of oxygen in the water, release of toxins in sediment, and the eventual death of aquatic organisms. Trash & Debris Examples include paper, plasfic, leaves, grass cuttings, and food waste, which may have a significant impact on the recreational value of a water body and aquatic habitat. Excess organic matter can create a high biochemical oxygen demand in a stream and thereby lower its water quality. In areas where stagnant water is present, the presence of excess organic matter can promote septic conditions resulting in the growth of undesirable organisms and the release of odorous and hazardous compounds such as hydrogen sulfide. Oxygen-Demanding Substances Biodegradable organic material as well as chemicals that react with dissolved oxygen in water to form other compounds. Compounds such as ammonia and hydrogen sulfide are examples of oxygen-demanding compounds. The oxygen demand of a substance can lead to depletion of dissolved oxygen in a water body and possibly the development of septic conditions. Oil & Grease Characterized as high high-molecular weight organic compounds, primary sources of oil and grease are petroleum hydrocarbon products, motor products from leaking vehicles, oils, waxes, and high-molecular weight fatty acids. Elevated oil and grease content can decrease the aesthetic value of the water body, as well as the water quality. (1) Preconstruction control practices Preconstruction control measures may include any measures used to reduce erosion, sediment or other pollutants in storm water discharges. They may include, but not be limited to: Detenfion basins, infiltration basins, sediment basins, oil water separators, rock slope protecfion, exisfing erosion control, exisfing landscaping, lined ditches, energy dissipaters, restricted entry to and exit from the site, etc. to reduce sediment and other pollutants in storm water discharge.

The person responsible for pre-storm, post-storm, and storm event BMP inspection is Mike Burzinski, Craftsman Carlsbad I, LLC, and he can be reached at (760) 510-6419. The person responsible to ensure full compliance with the Permit and implementation of all elements of the SWPPP including preparafion of the annual compliance evaluafion and the eliminafion of all unauthorized discharges is Mike Burzinski, Craftsman Carlsbad I, LLC, and he can be reached at (760) 510-6419. 6. Erosion Control Erosion control, also referred to as "soil stabilization" is the most effective way to retain soil and sediment on the constmction site. The most efficient way to address erosion control is to preserve existing vegetation where feasible, to limit disturbance, and to stabilize and revegetate disturbed areas as soon as possible after grading or constmction. Particular attention must be paid to large mass-graded sites where the potential for soil exposure to the erosive effects of rainfall and wind is great. Mass graded constmction sites may be exposed for several years while the project is being built out. Thus, there is potential for significant sediment discharge from the site to surface waters. At a minimum, the discharger/operator must implement an effective combination of erosion and sediment control on all disturbed areas during the rainy season. These disturbed areas include rough graded roadways, slopes, and building pads. Until permanent vegetation is established, soil cover is the most cost-effective and expeditious method to protect soil particles from detachment and transport by rainfall. Temporary soil stabilization can be the single-most important factor in reducing erosion at constmction sites. The discharger shall consider measures such as: covering with mulch, temporary seeding, soil stabilizers, binders, fiber rolls or blankets, temporary vegetation, permanent seeding, and a variety of other measures. The SWPPP shall include a description of the erosion control practices, including a time schedule, to be implemented during constmction to minimize erosion on disturbed areas of a constmction site. The discharger must consider the full range of erosion control BMPs. The discharger must consider any additional site-specific and seasonal conditions when selecting and implementing appropriate BMPs. The above listed erosion control measures are examples of what should be considered and are not exclusive of new or innovative approaches currentiy available or being developed. '•'^I^^- 23 H:\SWPPPU470/0O2\Main Hunsaker & Associates San Diego, inc. STORM WATER POLLUTION PREVENTION PLAN La Suvera CDP 04-16 The SWPPP shall include: (1) An outiine ofthe areas of vegetative soil cover or native vegetation onsite which will remain undisturbed during the constmction project. There are no areas of vegetative soil cover or native vegetation on-site, which will remain undisturbed during the construction project. (2) An outiine of all areas of soil disturbance including cut or fill areas which will be stabilized during the rainy season by temporary or permanent erosion control measures, such as seeding, mulch, or blankets, etc. The rainy season is typically described in California as from October 1 to April 30. However, the permit requires compliance on a year round basis as oufiined by this storm water pollution prevention plan. All areas of soil disturbance including cut and fill as well as the proposed BMPs are shown on the Grading Plans for La Suvera located at the jobsite. Example BMPs for erosion control measures during construcfion include, but are not limited to, the use of geotextiles, erosion control blankets, tackifier and bonded fiber matrix (BFM). Erosion control measures will be installed and functioning on a year round basis and pursuant to the plan notes and the project construcfion activity schedule located in Appendix H. (3) An outiine of the areas of soil disturbance, cut, or fill which will be left exposed during any part of the rainy season, representing areas of potential soil erosion where sediment control BMPs are required to be used during constmction. The owner shall designate any areas of cut or fill that will be exposed on a year round basis where sediment controls are implemented on the below referenced exhibits. Sediment control measures will be installed and functioning on a year round basis and pursuant to the plan notes and the project construction activity schedule located in Appendix H. All disturbed areas will be temporarily stabilized on a year round basis. Example BMPs for sediment control measures during construcfion include, but are not limited to, the use of silt fences, gravel bags, fiber rolls and sedimentation basins. When placing gravel bags around all exisfing inlets within the vicinity and downstream of the construction site special caution needs to be taken. If these affected inlets are in a traveled roadway it will be the responsibility of the owner to take precautionary measures. These measures might include warning signs, cones, construcfion horses P'*P^ ^ 24 H:\SWPPP\2470/002\Mam Hunsaker & Associates San Diego, Inc. STORM WATER POLLUTION PREVENTION PLAN La Suvera CDP 04-16 with flashing lights, or whatever means necessary to warn motorists, bicyclists, and/or pedestrians that there are gravel bags in the traveled way. The owner will be responsible to document and date these areas of temporary sediment control, when applicable, on the Wall Map for La Suvera (Exhibit E5) located at the jobsite. (4) A proposed schedule for the implementation of erosion control measures. Appendix H presents the project construction activity schedule for the La Suvera project, which incorporates the implementation of erosion control measures. Events occur throughout the life of a construction project that may alter the schedule; therefore, it will be revised/amended by the owner when appropriate. All revisions and/or amendments will be dated and inserted into Appendix H. Superseded schedules will be marked superseded and confinue to be a part of this SWPPP. The SWPPP shall include a description of the BMPs and control practices to be used for both temporary and pennanent erosion control measures. A description of example BMPs and control practices used for both temporary and permanent erosion control measures are discussed in Appendix Q and Appendix S. Also, see Storm Water Management Plan prepared by Hunsaker & Associates San Diego, Inc. which addresses permanent erosion control measures. The SWPPP shall include a description of the BMPs to reduce wind erosion at all times, with particular attention paid to stock-piled materials. The primary impacts of wind erosion (dust control) will be controlled through water application on main driving areas, construction of gravel access road entrance/exits, and limitafion of off-road driving. The stockpiled soil/materials will be covered and secured by erosion and sedimentation control as determined by the owner. An example would be covering the stock piled soil with visqueen and securing the visqueen at the toe ofthe stockpile with gravel bags. The BMPs that will be used to reduce wind erosion during construction ofthe project will be determined in the field by the contractor and documented on the Wall Map for La Suvera (Exhibit E5) located at the jobsite.

These measures include the use of such BMPs as blankets, reinforced channel liners, soil cement, fiber matrices, geotextiles, or other erosion resistant soil coverings or treatments. Where background native vegetation covers less than 100 percent of the surface, such as in arid areas, the 70 percent coverage criteria is adjusted as follows: If the native vegetation covers 50 percent of the ground surface, 70 percent of 50 percent (.70 X .50=.35) would require 35 percent total uniform surface coverage. A copy of the Notice of Termination (NOT) Form and instructions are presented in Appendix F. Sediment Control The SWPPP shall include a description or illustration of BMPs which will be implemented to prevent a net increase of sediment load in storm water discharge relative to preconstmction levels. Sediment control BMPs are required at appropriate locations along the site perimeter and at all operational intemal inlets to the storm drain system at all times during the rainy season. Sediment control practices may include filtration devices and barriers (such as fiber rolls, silt fence, straw bale barriers, and gravel inlet filters) and/or settling devices (such as sediment traps or basins). Effective filtration devices, barriers, and settling devices shall be selected, installed and maintained properiy. A proposed schedule for deployment of sediment control BMPs shall be included in the SWPPP. These are the most basic measures to prevent sediment from leaving the project site and moving into receiving waters. Limited exemptions may be authorized by the RWQCB when work on active areas precludes the use of sediment control BMPs temporarily. Under these conditions, the SWPPP must describe a plan to establish perimeter controls prior to the onset of rain. PreparedBy: Hunsaker & Associates San Diego. Inc. 26 H:\SWPPP\2470/002\Main STORM WATER POLLUTION PREVENTION PLAN La Suvera CDP 04-16 During the nonrainy season, the discharger is responsible for ensuring that adequate sediment control materials are available to control sediment discharges at the downgrade perimeter and operational inlets in the event of a predicted storm. The discharger shall consider a full range of sediment controls, in addition to the controls listed above, such as straw bale dikes, earth dikes, bmsh barriers, drainage swales, check dams, subsurface drain, sandbag dikes, fiber rolls, or other controls. At a minimum, the discharger/operator must implement an effective combination of erosion and sediment control on all disturbed areas during the rainy season. Ifthe discharger chooses to rely on sediment basins for treatment purposes, sediment basins shall, at a minimum, be designed and maintained as follows: Option 1: Pursuant to local ordinance for sediment basin design and maintenance, provided that the design efficiency is as protective or more protective of water quality than Option 3. OR Option 2: Sediment basin(s), as measured from the bottom of the basin to the principal outiet, shall have at least a capacity equivalent to 3,600 cubic feet of storage per acre draining into the sediment basin. The length ofthe basin shall be more than twice the width of the basin. The length is detennined by measuring the distance between the inlet and the outiet; and the depth must not be less than three feet nor greater than five feet for safety reasons and for maximum efficiency. OR Option 3: Sediment basin(s) shall be designed using the standard equation: As-1.2Q/Vs Where: As is the minimum surface area for trapping soil particles of a certain size; Vs is the settling velocity of the design particle size chosen; and Q=C x I x A where Q is the discharge rate measured in cubic feet per second; C is the mnoff coefficient; I is the precipitation intensity for the 10-year, 6-hour rain event and A is the area draining into the sediment basin in acres. The design particle size shall be the smallest soil grain size determined by wet sieve analysis, or the fme silt sized (0.01mm) particle, and the Vs used shall be 100 percent of the calculated settling velocity. •""P^By: 27 H:\SWPPPU470/002\Main Hunsaker & Associates San Diego, Inc. STORM WATER POLLUTION PREVENTION PLAN La Suvera CDP 04-16 The length is determined by measuring the distance between the inlet and the outiet; the length shall be more than twice the dimension as the width; the depth shall not be less than three feet nor greater than five feet for safety reasons and for maximum efficiency (two feet of storage, two feet of capacity). The basin(s) shall be located on the site where it can be maintained on a year-round basis and shall be maintained on a schedule to retain the two feet of capacity; OR Option 4: The use of an equivalent surface area design or equation, provided that the design efficiency is as protective or more protective of water quality than Option 3. A sediment basin shall have a means for dewatering within 7-calendar days following a storm event. Sediment basins may be fenced if safety (worker or public) is a concem. The outflow from a sediment basin that discharges into a natural drainage shall be provided with outiet protection to prevent erosion and scour of the embankment and channel; The discharger must consider any additional site-specific and seasonal conditions when selecting and designing sediment control BMPs. The above listed sediment control measures are examples of what should be considered and are not exclusive of new or innovative approaches currently available or being developed. The SWPPP shall include a description of the BMPs to reduce the tracking of sediment onto public or private roads at all times. These public and private roads shall be inspected and cleaned as necessary. Road cleaning BMPs shall be discussed in the SWPPP and will not rely on the washing of accumulated sediment or silt into the storm drain system. A description of BMPs and control pracfices used for both temporary and permanent sediment control measures are discussed in Appendices Q and S and shown on SWPPP Wall Map. Also, see Storm Water Management Plan prepared by Hunsaker & Associates San Diego, Inc. which addresses permanent sediment control measures. There are no sediment basins proposed for the La Suvera project. Therefore, no addifional informafion regarding their design criteria has been included with this SWPPP. Temporary sediment control measures are shown on the Wall Map for La Suvera (Exhibit E5) located at the jobsite. Sediment control measures will be installed and funcfioning on a year round basis and pursuant to the plan notes and the project construction activity schedule located in Appendix H. Events occur throughout the life of a construction project, which may alter the schedule; therefore it will be PreparedBy: 28 H:\SWPPP\2470/002\Main Hunsaker & Associates San Diego, Inc. STORM WATER POLLUTION PREVENTION PLAN La Suvera CDP 04-16 revised/amended by the contractor/owner when appropriate. All revisions and/or amendments will be dated and attached. Superseded schedules will be marked superseded and continue to be a part of this SWPPP. The tracking of sediment onto public streets is normally attributed to construction vehicles driving through unpaved areas. Prior to street paving, construction site exits will be protected with a gravel roadbed with 3-inch minus course aggregate and a minimum of 6 inches deep. The graveled areas should be installed with a minimum length of 50 feet and width of the road (minimum width of road is 12 feet). The public roads shall be inspected and cleaned as necessary. The stabilized construction site entrance/exit for the site will be as shown on the Wall Map for La Suvera (Exhibit E5) located at the jobsite. Due to contractor/owner preferences, or construction activity it may be deemed necessary to change the delineated location or add an addifional one. Therefore, the owner will be responsible to delineate, on the Wall Map for La Suvera, the location of the entrance/exits. See Appendix Q for road cleaning BMPs. 9. Non-Storm Water Management Describe all non-storm water discharges to receiving waters that are proposed for the constmction project. Non-storm water discharges should be eliminated or reduced to the extent feasible. Include the locations of such discharges and descriptions of all BMPs designed for the control of pollutants in such discharges. Onetime discharges shall be monitored during the time that such discharges are occurring. A qualified person should be assigned the responsibility for ensuring that no materials other than storm water are discharged in quantities which will have an adverse effect on receiving waters or storm drain systems (consistent with BAT/BCT), and the name and contact number of that person should be included in the SWPPP document. Discharging sediment-laden water which will cause or contribute to an exceedance of the applicable RWQCB's Basin Plan from a dewatering site or sediment basin into any receiving water or storm drain without filtration or equivalent treatment is prohibited. Non-storm water (unregulated flows) that discharge to receiving waters can include but are not limited to line flushing, landscape irrigafion, tesfing, street washing, and dewatering. Although these flows may occur on-site as vegetation is established, pipes are flushed and streets are washed, efforts will be made to control these flows to the maximum extent practicable. It is the Discharger's responsibility to show locafions of such discharges and descriptions of BMPs for the control of pollutants in such discharges (if applicable) on the SWPPP Wall Map. Prepared By: 29 H:\SWPPP\2470/002\Main Hunsaker & Associates San Diego. Inc. STORM WATER POLLUTION PREVENTION PLAN La Suvera CDP 04-16 Note to Discharger: Obtain any line flushing, dewatering, etc. permits required by the RWQCB for the construction of the project and place a copy in Appendix K. To the extent that the Regional Water Quality Control Board (RWQCB) has issued permits for the discharge of any non-storm water, the discharger shall comply with those addifional permits. The qualified person responsible for ensuring that no materials other than storm water are discharged in quantities which will have an adverse effect on receiving waters or storm drain systems (consistent with BAT/BCT), is Glen Carson, CaIco West Financial, Inc., and can be reached at (760) 644-2533. 10. Post-Constmction Storm Water Management The SWPPP shall include descriptions of the BMPs to reduce pollutants in storm water discharges after all constmction phases have been completed at the site (Post- Constmction BMPs). Post-Constmction BMPs include the minimization of land disturbance, the minimization of impervious surfaces, treatment of storm water mnoff using inflitration, detention/retention, biofllter BMPs, use of efficient irrigation systems, ensuring that interior drains are not connected to a storm sewer system, and appropriately designed and constmcted energy dissipation devices. These must be consistent with all local post-constmction storm water management requirements, policies, and guidelines. The discharger must consider site-specific and seasonal conditions when designing the control practices. Operation and maintenance of control practices after constmction is completed shall be addressed, including short-and long-term funding sources and the responsible party. For a description of post-construction storm water management BMPs, see Appendix S. For a further discussion of post-construction storm water management's BMPs including sizing, maintenance responsibility and funding, see Storm Water Management Plan (SWMP) prepared by Hunsaker & Associates San Diego, Inc. The purpose of the SWMP is to address the water quality impacts resulting from the development of the proposed La Suvera project. The proposed project design has incorporated post-construction BMPs in order to satisfy all requirements detailed in the City of Carlsbad's "Standard Urban Storm Water Mitigafion Plan (SUSMP), and describes how the project will comply with these regulafions. All calculafions are consistent with criteria set forth by the Regional Water Quality Control Board's Order No. 2001-01, and the City of Carlsbad Storm Water Standards. Three (3) flow-based curb inlet filter BMPs will be placed at the three receiving storm drain inlets within the La Suvera site. The 85'^^ percentile runoff will be treated in the proposed FloGard (or an equivalent approved curb inlet filter treatment unit) curb inlet filter units prior to discharging from the site. Prepared By: 30 HASWPPP\2470/002\Main Hunsaker & Associates San Diego, Inc. STORM WATER POLLUTION PREVENTION PLAN La Suvera CDP 04-16 Education of homeowners is an important way to help reduce pollutants in the post- construction project. Currently in San Diego County, there is a public outreach program in place called "Think Blue." The "Think Blue" program's goal is to educate the public regarding storm water pollution. The owner will be responsible to obtain and disseminate this informafion. Informafion regarding the "Think Blue" program can be obtained by dialing 1-888-THINK BLUE or 1-888-844-6525. Sample Homeowners information package can be found in Appendix O. The owner shall provide labeling/stenciling (or other approved method) of all inlets/catch basins. The owner will be responsible to obtain informafion regarding the jurisdictionally approved method for labeling. The responsible party for long-term maintenance and funding of the above-described post-construction BMPs is the Homeowner's Association. The owner cannot terminate their Notice of Intent (NOI) until the construction site is stabilized and meets the requirements of Section A: 7 Stabilization. This includes a notice of termination to be filed along with a post-construction storm water operation and management plan, which includes the mechanism for funding of current and long- term maintenance of post-construction BMPs. Good housekeeping practices will also be implemented for the La Suvera project. These practices include the controlled application of carefully selected fertilizers and pesficides, and a general on-site maintenance and disposal program to keep the site free of litter and debris. 11. Maintenance. Inspection, and Repair The SWPPP shall include a discussion of the program to inspect and maintain all BMPs as identified in the site plan or other narrative documents throughout the entire duration of the project. A qualified person will be assigned the responsibility to conduct inspections. The name and telephone number of that person shall be listed in the SWPPP document. Inspections will be perfonned before and after storm events and once each 24-hour period during extended storm events to identify BMP effectiveness and implement repairs or design changes as soon as feasible depending upon field conditions. Equipment, materials, and workers must be available for rapid response to failures and emergencies. All conective maintenance to BMPs shall be performed as soon as possible after the conclusion of each storm depending upon worker safety. For each inspection required above, the discharger shall complete an inspection checklist. At a minimum, an inspection checklist shall include: a. Inspection date. Prepared By: 31 H:\SWPPP\2470A»2\Main Hunsaker & Associates San Diego. Inc. STORM WATER POLLUTION PREVENTION PLAN La Suvera CDP 04-16 b. Weather information: best estimate of beginning of storm event, duration of event, time elapsed since last storm, and approximate amount of rainfall (inches). c. A description of any inadequate BMPs. d. If it is possible to safely access during inclement weather, list observations of all BMPs: erosion controls, sediment controls, chemical and waste conttols, and non-storm water controls. Othenvise, list result of visual inspection at relevant outfall, discharge point, or downstream location and projected required maintenance activities. e. Conective actions required, including any changes to SWPPP necessary and implementation dates. f. Inspectors name, titie, and signature. The dischargers shall prepare their inspection checklists using the inspection checklist form provided by the SWRCB or RWQCB or on forms that contain the equivalent information. Appendix G presents the Inspection Reports. The most important aspects of maintenance, inspecfion, and repair are record keeping, tracking, and documentation practices. Inspections will be performed before and after storm events and once each 24-hour period during extended storm events. The project area will be regularly inspected to ensure that it is maintained in good and effective condifion. At a minimum an onsite inspecfion should be performed and documented once a month during the dry season, May 1 through September 30, and once a week from October 1 through April 30. The contact person to be responsible for answering various maintenance quesfions regarding this project is Glen Carson, CaIco West Financial, Inc., and he can be reached at (760) 644-2533. 12. Training Individuals responsible for SWPPP preparation, implementation, and permit compliance shall be appropriately trained, and the SWPPP shall document all training. This includes those personnel responsible for installation, inspection, maintenance, and repair of BMPs. Those responsible for overseeing, revising, and amending the SWPPP shall also document their training. Training should be both formal and informal, occur on an ongoing basis when it is appropriate and convenient, and should include training/workshops offered by the SWRCB, RWQCB, or other locally recognized agencies or professional organizations. Prepared By: 32 H:\SWPPP\2470/002\Main Hunsaker & Associates San Diego. liK. STORM WATER POLLUTION PREVENTION PLAN La Suvera CDP 04-16 The goal of the storm water pollution prevention training program is to inform owners, employees, contractors, and subcontractors of their levels of responsibility for components and goals of the SWPPP. This training program is a preventative maintenance technique, because when properly infonned, employees, owners/contractors, and subcontractors have increased awareness and are more capable of prevenfing spills, responding safely and effectively to accidents, and recognizing situafions that could lead to storm water contaminafion. Storm water pollufion prevenfion training shall be provided regularly and accomplished by either of the following methods: (1) Owners or Owners representative needs to be trained and (2) Subcontractors need to be trained by the following methods: owner or owners representative can provide the training or subcontractor can do their own training and provide written proof of training (to include name of training session, date, and signature of attendee) to owner or owners representative for all their personnel involved with the project. A training session should be held at the onset of all construction activities and continue throughout the construction project. Owner and subcontractors should attend all training sessions. Topics can include, but are not limited to: spill prevenfion and response, inspecfion records, locafions and functions of sediment control devices, good housekeeping, and material and waste management pracfices. Attendance records should be kept for each training session. Inspecfion Reports should be distributed to all personnel who will be performing the monitoring and reporting. Appendix D presents the completed Training Logs and is provided so that all training sessions can be documented. This log will be revised/amended by the owner/contractor when appropriate. Original blank training logs are in Appendix B. Records generated from all inspecfions, maintenance operafions, compliance certificafion, and non-compliance reporting should be retained for a period of at least three years from the date generated. These records do not have to be submitted with the excepfion of noncompliance reporting. The project records for monitoring and reporting in accordance with the SWPPP will be maintained at the construcfion site office. 13. List of Contractors/Subcontractors The SWPPP shall include a list of names of all contractors, (or subcontractors) and individuals responsible for implementation of the SWPPP. This list should include telephone numbers and addresses. Specific areas of responsibility of each subcontractor and emergency contact numbers should also be included. Provided, in Appendix E, is a form which the owner shall complete at onset of construction which lists the contractors and subcontractors responsible for implementafion of this SWPPP. The contractors and subcontractors have been through a training program, as oufiined in the recommended training procedures of this SWPPP. They have also been informed of the recommended good housekeeping practices and control measures. Prepared By: 33 H:\SWPPP\2470/002\Main Hunsaker & Associates San Diego, Inc.

Required Changes The RWQCB may require the discharger to conduct additional site inspections, to submit reports and certifications, or perform sampling and analysis. 2. Implementation a. The requirements of this Section shall be implemented at the time of commencement of constmction activity (see also Section A. 2. Implementation Schedule). The discharger is responsible for implementing these requirements until constmction activity is complete and the site is stabilized. b. For ongoing constmction activity involving a change in ownership of property covered by this General Permit, the new owner must complete a NOI and implement the requirements of this Section concunent with the change of ownership. For changes of information, the owner must follow instmctions in C. 7. Special Provisions for Constmction Activity of the General Permit. 3. Site Inspections Qualifled personnel shall conduct inspections of the constmction site prior to anticipated storm events, during extended storm events, and after actual storm events to identify areas contributing to a discharge of storm water associated with constmction activity. The name(s) and contact number(s) of the assigned inspection personnel shall be listed in the SWPPP. Pre-storm inspections are to ensure that BMPs are properly installed and maintained; post-storm inspections are to assure that the BMPs have functioned adequately. During extended storm events, inspections shall be required each 24-hour period. Best Management Practices (BMPs) shall be evaluated for adequacy and proper implementation and whether additional BMPs are required in accordance with the terms of the General Permit (see language in Section All. Maintenance, Inspection, and Repair). Implementation of nonstorm water discharge BMPs shall be verified and their effectiveness evaluated. One time discharges of non-storm water shall be inspected when such discharges occur. 4. Compliance Certification Each discharger or qualified assigned personnel listed by name and contact number in the SWPPP must certify annually that constmction activities are in compliance with the requirements of this General Permit and the SWPPP. This Certification shall be based upon the site inspections required in Item 3 of this Section. The certification must be completed by July 1 of each year. A blank original Annual Compliance Certificafion form is located in Appendix B. The Annual Compliance Certificafion is to be completed on July 1 of every year throughout Prepared By: 35 H:\SWPPP\2470/002\Main Hunsaker & Associates San Diego, Inc. STORM WATER POLLUTION PREVENTION PLAN La Suvera CDP 04-16 construction. Please retain all completed Annual Compliance Certifications in Appendix C. The certification does not need to be submitted to the RWQCB. 5. Noncompliance Reporting Dischargers who cannot certify compliance, in accordance with Item 4 of this Section and/or who have had other instances of noncompliance excluding exceedances of water quality standards as defined in section B. 3. Receiving Water Limitations Language, shall notify the appropriate RWQCB within 30 days. Corrective measures should be implemented immediately following discovery that water quality standards were exceeded. The notifications shall identify the noncompliance event, including an initial assessment of any impact caused by the event; describe the actions necessary to achieve compliance; and include a time schedule subject to the modifications by the RWQCB indicating when compliance will be achieved. Noncompliance notifications must be submitted within 30-calendar days of identification of noncompliance. If Craftsman Carlsbad I, LLC cannot certify compliance as described above they will be responsible to prepare a corrective acfion plan and submit the plan pursuant to the above guidelines to: California Regional Water Quality Control Board - Region 9 9174 Sky Park Court, Suite 100 Carlsbad, California 92123 Telephone Number (858) 467-2952 6. Monitoring Records Records of all inspections, compliance certifications, and noncompliance reporting must be retained for a period of at least three years from the date generated. With the exception of noncompliance reporting, dischargers are not required to submit these records. Prepared By: 36 H:\SWPPP\2470/002\Main Hunsaker & Associates San Diego, Inc. STORM WATER POLLUTION PREVENTION PLAN La Suvera CDP 04-16 7. Monitoring Program for Sedimentation/Siltation Dischargers of storm water associated with constmction activity that directiy enters a water body listed in Attachment 3 shall conduct a sampling and analysis program for the pollutants (sedimentation/siltation or turbidity) causing the impairment. The discharger shall monitor for the applicable parameter. If the water body is listed for sedimentation or siltation, samples should be analyzed for Settieable Solids (ml/1) and Total Suspended Solids (mg/1). Altematively or in addition, samples may be analyzed for suspended sediment concentration according to ASTM D3977-97. If the water body is listed for turbidity, samples should be analyzed for turbidity (NTU). Discharges that flow through tributaries that are not listed in Attachment 3 or that flow into Municipal Separate Storm Sewer Systems (MS4) are not subject to these sampling and analysis requirements. The sampling and analysis parameters and procedures must be designed to determine whether the BMPs installed and maintained prevent discharges of sediment from contributing to impairment in receiving waters. Samples shall be collected during the first two hours of discharge from rain events which result in a direct discharge to any water body listed in Attachment 3. Samples shall be collected during daylight hours (sunrise to sunset). Dischargers need not collect more than four (4) samples per month. All samples shall be taken in the receiving waters and shall be representative of the prevailing conditions of the water bodies. Samples shall be collected from safely accessible locations upstream of the constmction site discharge and immediately downstream from the last point of discharge. For laboratory analysis, all sampling, sample preservation, and analyses must be conducted according to test procedures under 40 CFR Part 136. Field samples shall be collected and analyzed according to the specifications of the manufacturer of the sampling devices employed. Portable meters shall be calibrated according to manufacttirer's specification. All field and/or laboratory analytical data shall be kept in the SWPPP document, which is to remain at the constmction site at all times until a Notice of Termination has been submitted and approved. 8. Monitoring Program for Pollutants Not Visuallv Detectable in Storm Water A sampling and analysis program shall be developed and conducted for pollutants which are not visually detectable in storm water discharges, which are or should be known to occur on the constmction site, and which could cause or contribute to an exceedance of water quality objectives in the receiving water. Pollutants that should be considered for inclusion in this sampling and analysis program are those identified in Sections A.S.b. and A.5.C. Prepared By: 37 H:\SWPPP\2470/002\Main Hunsaker & Associates Sao Diego, Inc. STORM WATER POLLUTION PREVENTION PLAN La Suvera CDP 04-16 Constmction materials and compounds that are not stored in water-tight containers under a water-tight roof or inside a building are examples of materials for which the discharger may have to implement sampling and analysis procedures. The goal of the sampling and analysis is to determine whether the BMPs employed and maintained on site are effective in preventing the potential pollutants from coming in contact with storm water and causing or contributing to an exceedance of water quality objectives in the receiving waters. Examples of constmction sites that may require sampling and analysis include: sites that are known to have contaminants spilled or spread on the ground; sites where constmction practices include the application of soil amendments, such as gypsum, which can increase the pH of the mnoff; or sites having uncovered stockpiles of material exposed to storm water. Visual observations before, during, and after storm events may trigger the requirement to collect samples. Any breach, malfunction, leakage, or spill observed which could result in the discharge of pollutants to surface waters that would not be visually detectable in storm water shall trigger the collection of a sample of discharge. Samples shall be collected at all discharge locations which drain the areas identified by the visual observations and which can be safely accessed. For sites where sampling and analysis is required, personnel trained in water quality sampling procedures shall collect storm water samples. A sufficientiy large sample of storm water that has not come in contact with the disturbed soil or the materials stored or used on-site (uncontaminated sample) shall be collected for comparison with the discharge sample. Samples shall be collected during the first two hours of discharge from rain events that occur during daylight hours and which generate mnoff. The uncontaminated sample shall be compared to the samples of discharge using field analysis or through laboratory analysis. Analyses may include, but are not limited to, indicator parameters such as: pH, specific conductance, dissolved oxygen, conductivity, salinity, and TDS. For laboratory analysis, all sampling, sample preservation, and analyses must be conducted according to test procedures under 40 CFR Part 136. Field discharge samples shall be collected and analyzed according to the specifications of the manufacturer of the sampling devices employed. Portable meters shall be calibrated according to manufacturer's specification. All field and/or analytical data shall be kept in the SWPPP document, which is to remain at the constmction site at all times until a Notice of Termination has been submitted and approved. See Appendix J for projects SWSAS which addresses the above requirements. 38 Prepared By: H:\SWPPP\2470/002\Main Hunsaker & Associates San Diego. Inc. STORM WATER POLLUTION PREVENTION PLAN La Suvera CDP 04-16 SECTION C: STANDARD PROVISIONS FOR CONSTRUCTION ACTIVITY 1. Dutv to Complv The discharger must 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. The discharger shall comply with effluent standards or prohibitions established under Section 307(a) of the CWA for toxic pollutants wdthin 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. 2. General Permit Actions 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. 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. Need to Halt or Reduce Activitv 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. Dutv 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. 39 Prepared By: H:\SWPPP\2470/002y^ain Hunsaker & Associates San Diego, Inc.

STORM WATER POLLUTION PREVENTION PLAN La Suvera CDP 04-16 SAMPLING OF SILT, SEDIMENT AND NON-VISIBLE POLLUTANTS Background On April 26, 2001, the State Water Resources Control Board modified the findings and inonltoring conditions in the General Construction Permit 99- 08-DWQ to Include a sampling and analysis program for non-visibly detected pollutants. Craftsman Carlsbad I, LLC hereby modifies Its Storm Water Pollution Prevention Plan (SWPPP) to incorporate Finding 15 and to provide a procedure by which sediment and non-visible pollutants will be identified, sampled and analyzed. Sedimentation Monitoring Craftsman Carlsbad I, LLC's development activities at La Suvera do not discharge directly into a water body listed in Attachment 3 of the General Permit (Clean Water Act § 303.d Water Bodies Listed for Sedimentation). Therefore, this Plan does not include procedures addressing Section 8.7 ofthe General Permit. Non-Visible Pollutant Monitoring (Source Identification) Pursuant to sections A.S.b (2), (3) and (4) and section A.5.C. (1) and (2), Craftsman Carlsbad I, LLC has considered three classes of non-visible pollutants, which may be of concern. These are: pre-construction residues, construction activities, and construction materials. Pre-Construction Residues The Phase 1 Hazardous Substance Contamination Site Assessment ("Phase I Environmental Site Assessmenf) that was conducted by Project Resources Inc. on October 7, 1999, concluded that historical use of the land before commencement of development at the site, was undeveloped, vegetated. No evidence of sumps, drums, underground storage tanks, pipelines with petroleum hydrocarbons, hazardous substances, acutely hazardous materials or hazardous waste, pumps, tanks, clarifiers or septic tanks/leach fields were observed on site. Thus, Craftsman Carlsbad I, LLC has identified no potential sources of pollutants from previous uses. Piepared Bj-: DI I H:\SWPPP\2470/002\Main Hunsaker & Associates San Diego, inc. STORM WATER POLLUTION PREVENTION PLAN La Suvera CDP 04-16 Construction Activities During the construction process. Craftsman Carlsbad I, LLC and its sub- contractors will use a mix of heavy equipment and vehicles typical for construction activities such as mass and finished grading, paving, trenching, homebuilding, road construction, and transport of building supplies. Operation and maintenance of this heavy equipment causes Craftsman Carlsbad I, LLC to identify oil, grease and petroleum hydrocarbons as potential pollutants. Construction Materials Receiving Waters Beneficial Uses Appendix I identifies all construction materials commonly used in the development process that may be potential sources of pollutants. Craftsman Carlsbad I, LLC's storm water discharges to an unnamed tributary of Batiquitos Lagoon, over a mile away (Hydrologic Sub area 904.51). The unnamed tributary of Batiquitos Lagoon is a non-impacted watenvay that does not require testing for sedimentation/silt or turbidity. The surface water beneficial uses of the unnamed tributary of Batiquitos Lagoon, as identified in Table 2-3 of the Water Quality Control Plan for the San Diego Basin, are: REC1 - Contact Recreation: Includes uses of water for recreational activities involving body contact with water, where ingestion of water is reasonably possible. These uses include, but are not limited to, swimming, wading, water-skiing, skin and SCUBA diving, surfing, white water activities, fishing, or use of natural hot springs. REC2 - Non-Contact Recreation: Includes the uses of water for recreational involving proximity to water, but not normally involving body contact with water, where ingestion of water is reasonably possible. These uses include, but are not limited to, picnicking, sunbathing, hiking, camping, boating, tide pool and marine life study, hunting, sightseeing, or aesthetic enjoyment in conjunction with the above activities. EST - Estuarine Habitat: Includes uses of water that support terrestrial ecosystems including, but not limited to, preservation or enhancement of terrestrial habitats, vegetation, wildlife, (e.g., mammals, birds, reptiles, amphibians, invertebrates), or wildlife water and food sources. MAR - Marine Habitat: Includes uses of water that support marine ecosystems including, but not limited to, preservation or enhancement of marine habitats, vegetation such as kelp, fish, shellfish, or wildlife (e.g., marine mammals, shorebirds). PreparedBy: Dl Hunsaker & Associates San Diego, Inc. H:\SWPPP\2470/002\Main STORM WATER POLLUTION PREVENTION PLAN La Suvera CDP 04-16 WILD - Wildlife Habitat: Includes uses of water that support estuarine ecosystems including, but not limited to, preservation or enhancement of estuarine habitats, vegetation, fish, shellfish, or wildlife (e.g., estuarine mammals, waterfowl, shorebirds). BIOL - Preservation of Biological Habitats of Special Significance: Includes uses of water that support designated areas or habitats, such as established refuges, parks, sanctuaries, ecological reserves, or Areas of Special Biological Significance (ASBS), where the preservation or enhancement of natural resources requires special protection. RARE - Rare, Threatened, or Endangered Species: Includes uses of water that support habitats necessary, at least in part, for the survival and successful maintenance of plant or animal species established under state or federal law as rare, threatened or endangered. MIGR - Migration of Aquatic Organisms: Includes uses of water that support habitats necessary for migration, acclimation between fresh and salt water, or other temporary activities by aquatic organisms, such as anadromous fish. Monitoring Program for Pollutants Not Visibly Detectable in Storm Water Craftsman Carlsbad I, LLC has developed a sampling and analysis program for pollutants not visibly detectable in storm water discharges, which are or should be known to occur on the construction site and which could cause or contribute to the exceedance of a water quality objective ("Pollutants of Concern"). Craftsman Carlsbad I, LLC has identified the following as potential pollutants of concem: Petroleum hydrocarbons, gypsum and cement products, fertilizers, and pesticides. Analytes for Analysis Based on the Pollutants of Concern identified above. Craftsman Carlsbad I, LLC will test each discharge point and control sample for the following analytes: 1. pH 2. Biological Oxygen Demand (BOD) 3. Nitrates 4. Total Dissolved Solids (TDS) 5. Oil & Grease Prepared By: DI H:\SWPPP\2470/002\Main Hunsaker & Associates San Diego, Inc. STORM WATER POLLUTION PREVENTION PLAN La Suvera CDP 04-16 Sample Locations Control Samples Sample Collection Training Personnel for Sampling Sample Events Hunsaker and Associates has identified two (2) discharge sampling points that in their opinion fairly represent the discharge contributions of Craftsman Carlsbad I, LLC's project to the greater watershed. See Exhibit J-1 (Active Outlet & Run-On Points) at the end of this section, and also on the Wall Map located at the jobsite. In addition to the discharge points identified above, Hunsaker and Associates has identified one (1) upgradient and one (1) ambient location, as shown on the Wall Map located at the jobsite. These control samples will be used to determine the relative contribution, if any, of Pollutants of Concern by Craftsman Carlsbad I, LLC's project. Grab-samples will be collected and preserved in accordance with Method 1060 of Standard Methods for the Examination of Water and Wastewater 20* Edition (1998). Provided, however, that no sample shall be required if sample locations cannot be safely accessed. Note: Sampling points may be dynamic due to changes in the field. Show any updates on the Wall Map. Craftsman Carlsbad I, LLC has engaged the services of Storm Water Compliance Specialists to provide the following training program: • One two-hour training session for site superintendents, merchant builders and sample collectors to be conducted prior to the commencement ofthe rainy season each year. • One on-site sample collection and sample preservation field class for designated sample collectors to be conducted before the commencement of the rainy season each year. • Follow up visits to review sampling results with Craftsman Carlsbad I, LLC management and make recommendations for modifications to BMPs or the testing program after each sampled rain event. If a determination is made that sampling is needed, collect storm water runoff samples regardless of the time of year, status of the construction site, or day of the week. Collect samples during the first two hours of runoff (during daylight hours). Storm water inspections and sample collections are required even during non-working days (including Prepared By: DI Hunsaker & Associates San Diego. Inc. H:\SWPPP\2470/002\Main STORM WATER POLLUTION PREVENTION PLAN La Suvera CDP 04-16 weekends and holidays). Dischargers need not collect any more than (4) four samples per month. Samples will also be taken if visual monitoring indicates there has been a breach malfunction, leakage, or spill from a BMP which could result in the discharge of stonn water containing non-visibly detectable pollutants, or if storm water comes into contact with soil amendments or other exposed materials or contamination and is allowed to be discharged. Weather-triggered Action Plan (WTAP) Prior to a Storm Event Implement BMPs 1) You are responsible to monitor the weather each dav (weatherchannel.com, accuweather.com, sandiegoinsider.com or an average of chosen sources shall be used). 2) 72 Hour Response Plan. If the probability of rain is 79% or greater within the next 72 hours, perform the following today: a) Perform an inspection to identify the work and prioritize that work in this 72 Hour Response Plan. b) Order sufficient materials to repair, supplement and improve BMPs. c) Implement and maintain those erosion and sediment control BMPs that require time to cure (tacifier, BFM, etc.) or that require more than 24 hours to implement. d) Perform maintenance now to free-up personnel for implementing BMPs as rains approach. 3) 24 Hour Response Plan. If the probability of rain is 70% or greater within the next 24 hours, perform the following Immediately: a) Perform an inspection to identify the work and prioritize that work in this 24 Hour Response Plan. b) Fiber rolls shall be placed back in their previous condition at back of sidewalk and secured in place. c) Perform and/or direct that streets get swept so that sediment is kept out of storm drains. d) Perform any remaining maintenance. Distribute materials ready to deploy to repair, supplement and improve BMPs. e) Schedule work force for emergency deployment. f) Cover all wash out pits with visqueen or equivalent thereof to avoid over-filling of washout area. g) Cover or store all pressure treated lumber, concrete bags, stucco bags, form oil and fuel. h) Clean up jobsite of miscellaneous trash and debris. i) All trash containers should be covered. •""P^^-™ ^ H:\SWPPP\2470/002\Main Hunsaker & Associates San Diego. IIK. STORM WATER POLLUTION PREVENTION PLAN La Suvera CDP 04-16 Sample Procedure j) Sawdust in chop yard area that could be exposed to rainfall must be removed or covered, k) Painter's temporary operational area must be cleaned up and paint disposed of and/or stored properly away from rain. I) The gas machine in the Plumber's temporary operational area must be cleaned and covered. Sampling and Analysis Strategy 1. Monitor weather forecast. If the probability of rain is 70% or greater during the next 24-72 hours, and forecasted storm is likely to constitute a Sampling Event, alert the sampling crews. 2. Call the lab to see if they can pick up and analyze the samples within the 24 hour holding time. 3. Perform a comprehensive and thorough pre-storm inspection and make the observations you will need to facilitate the required sampling in a safe manner. Record your observations in the inspection log in the SWPPP. The Primary purpose of this inspection is to ensure that the BMPs are properly installed and maintainecl. General Conditions 1) Make any necessary corrections, repairs and/or revisions to the BMPs, based on inspections. Note these actions on the Project 2) Wall Map and in the SWPPP logs. 3) Insure adequate quantities of additional BMP materials are stored onsite in case they are required during the storm to reinforce 4) or replace installed BMPs. 5) Make sure that all potential non-visible pollutants (example: caulking tubes, glues, sealants, lime bags, concrete bags, stucco bags are secured example: covered, moved, sealed or cleaned. 6) Remember that during extended storms events, inspections shall be required each 24 hour period. (See inspection forms in Appendix B) Monitor weather forecasts, and alert sampling crews when the probability of rain exceeds 70% during the next 24 hours and is likely to create a sampling event as defined by previous section "Sampling Event". 3. At the commencement of a Sampling Event, disperse sampling discharge points with sample kit provided by the environmental laboratory. Each sampling crew will collect manual grab samples. To collect the sample, place the sample container with open-end facing upstream directly into the stream of water. Be sure not to contaminate the inside of the container. This will be done for each container in the kit. Prepared By: DI Hunsaker £ Associates San Diego. Inc H:\SWPPP\247O/O02\Main STORM WATER POLLUTION PREVENTION PLAN La Suvera CDP 04-16 Sample Analysis Once the samples are collected, each sampling crew will complete a Chain of Custody Record (provided by the environmental laboratory) and label the sample. The information required is the name and signatures of the people collecting the sample in the field, the date and time, and location of sample. Sample crews will then deliver the samples to the site storm water manager. The samples shall be collected and analyzed according to the specifications of the manufacturer of the sampling devices. The site storm water manager will assure delivery of the samples to the designated environmental laboratory within 24 hours of the sample collection. Craftsman Carlsbad I, LLC has contracted with Storm Water Compliance Specialists to provide necessary sampling kits and perform analysis.

Anticipated situations, which might cause Craftsman Carlsbad I, LLC to revise its SWPPP or sampling program, include but are not limited to: • Comparison of analytical results with Benchmarks derived from the San Diego Basin Plan or the Multi-Sector Industrial Permit for analytes tested; • SWPPP monitoring that indicates changes in discharge locations or pollutants of concern Basin Plan Benchmarks The site is within the Batiquitos Lagoon drainage basin and is drained by an unnamed tributary of Batiquitos Lagoon, hydrologic unit basin number 4.51. The Water Quality Control Plan for the San Diego Basin ("Basin Plan") provides at Table 3-2 that the following concentrations not be exceeded more than 10% of the time during any one-year period. While Craftsman Carlsbad I, LLC does not believe that table 3-2 constitutes a discharge standard or limit, it will apply these concentrations as decision- making benchmark standards. Where such standards are not available through the basin plan. Craftsman Carlsbad I, LLC employs the benchmark standards set forth in the U.S. EPA Multi-Sector Industrial Permit for decision-making purposes. The applicable benchmarks are as follows. Analyte Bench Mark Concentration Reference PH 6.0-9.0 Table B U.S. EPA Multi- Sector Permit BOD 30 mg/L Table B U.S. EPA Multi- Sector Permit Nitrates (N03) 45 mg/L Basin Plan 3-10 TDS 500 mg/L Basin Plan Table 3-2 Oil and Grease 15 mg/L Table B U.S. EPA Multi- Sector Permit PreparedBy: Dl Hunsaker & Associates San Diego, Inc. H:\SWPPP\2470/002\Main STORM WATER POLLUTION PREVENTION PLAN La Suvera CDP 04-16 Exceedances of Benchmark Criteria When laboratory analysis shows that a tested analyte exceeds the benchmark concentration, Craftsman Carlsbad I, LLC, in conjunction with its consultants will perform a root cause analysis and prepare a Corrective Action Report (CAR) within 14 days of the receipt of the information. The root cause analysis identifying the probable causes of the exceedance and CAR describing the actions Craftsman Carlsbad I, LLC will take to attempt to reduce the exceedance will be implemented within 30 days of receipt of the laboratory information. Craftsman Carlsbad I, LLC will also submit copies of the analytical data, root cause analysis and CAR to the Regional Board within 30 days of receipt of the laboratory information following section B.5 of the General Permit. Compliance with Benchmark Data Where laboratory data for two consecutive rain events for any specific discharge point indicates that La Suvera's discharges at that point are below benchmarks for any analyte. Craftsman Carlsbad I, LLC will cease to test for that analyte at that discharge point. However, whenever the construction activities serviced by the discharge point in question are observed to have changed. Craftsman Carlsbad I, LLC will re-institute testing for the full suite of analytes described above. Change of Conditions Whenever SWPPP monitoring pursuant to Section B of the permit indicates a change in site conditions, which might affect the appropriateness of sampling points or the introduction of new pollutants of concern. Craftsman Carlsbacl I, LLC will review its testing protocols and revise them accordingly. Craftsman Carlsbad I, LLC will record all such revisions in its SWPPP.

Conduct tests, analyses and evaluations to determine whether a discharge of storm water is an illegal discharge or whether the requirements of this chapter are met. 4. Photograph any effluent stream, material or waste, material or waste container, container label, vehicle, waste treatment process, waste disposal site connection, or condition believed to contribute to storm water pollution or constitute a violation of this chapter. 5. Review and obtain a copy of the storm water pollution prevention plan , the Hazardous Materials Release Response Pian and Inventory, and/or any other documents, permits, manifests, logs or records that may be required of the facility from local, state or federal laws, regulations or codes in order to conduct operations or business on the premises.. 6. Require the facility operator to retain evidence, as instructed by the inspector, for a period not to exceed thirty (30) days. 7. Review and obtain copies of all storm water monitoring data compiled by the facility, if such monitoring is required of the facility. 15.12.120 Containment, cleanup, and notification of spills. Any person owning or occupying any premises who has knowledge of any release of significant quantities of materials, pollutants, or waste which may result in pollutants or non-storm water discharges entering the city's storm water conveyance system shall immediately take all reasonable action to contain, minimize, and clean up such release. Such person shall notify the city of Carlsbad of the occurrence and any other appropriate agency of the occurrence as soon as possible, but no later than twenty-four (24) hours from the time of the incident's occurrence. (Ord. NS-394 § 2 (part), 1997) 15.12.130 Testing, monitoring or mitigation requirements. A. The enforcement official may require that any person engaged in any activity and/or owning or operating any facility which causes or contributes to storm water pollution or contamination, illegal discharges, prohibited discharges and/or discharge of nonstorm water to the storm water conveyance system perform monitoring, including physical and chemical monitoring and/or analyses and furnish reports as the enforcement official may specify if: 1. The person, or facility owner or operator, fails to eliminate illegal or prohibited discharges within a specified time after receiving a written notice to do so by the enforcement official. 2. The enforcement official has documented repeated violations of this chapter by the person or facility owner or operator which has caused or contributed to storm water pollution. It is unlawrful for such person or facility owner or operator to fail or refuse to undertake and provide the monitoring, analyses, and/or reports specified. Specific monitoring criteria shall bear a relationship to the types of pollutants which may be generated by the person's activities or the facility's operations. If the enforcement agency has evidence that a pollutant is originating from a specific premises, then the enforcement agency may require monitoring for that pollutant regardless of whether said pollutant may be generated by routine activities or operations. The person or facility owner or operator shall be responsible for all costs of these activities, analyses and reports. B. Any persons required to monitor pursuant to subsection A of this section, shall implement a storm water monitoring program including, but not limited to, the following: 1. Routine visual monitoring for dry weather flows. 2. Routine visual monitoring for spills which may pollute storm water runoff. 3. A monitoring log including monitoring date, potential pollution sources, as noted in subsections 1 and 2 of this section, and a description of the mitigation measures taken to eliminate any potential pollution sources. C. The enforcement official may require a person, or facility owner or operator, to install or implement storm water pollution reduction or control measures, including, but not limited to, process modification to reduce the generation of pollutants if: 1. The person, or facility owner or operator fails to eliminate illegal or prohibited discharges after receiving a written notice from the enforcement official. 2. The person, or facility owner or operator, fails to implement a storm water pollution prevention plan, as required by the enforcement official. 3. The enforcement official has documented repeated violafions of this chapter any such person or facility owner or operator which has caused or contiibuted to storm water pollution. D. If tesfing, monitoring or mifigation required pursuant to this chapter are deemed no longer necessary by the enforcement official, then any or all of the requirements contained in subsecfions A, B, and C of this section, may be disconfinued. E. A storm water monitoring program prepared and implemented pursuant to any state-issued NPDES General Permit shall be deemed to meet the requirements of a monitoring program forthe purposes of this chapter. (Ord. NS-394 § 2 (part), 1997) 15.12.140 Concealment. Causing, permitting, aiding, abetfing or concealing a violatiori of any provision of this chapter is unlawful and shall consfitute a separate violafion of this chapter. (Ord. NS-394 § 2 (part), 1997) 15.12.150 Administrative code enforcement powers and procedures The enforcement agency and enforcement official can exercise any code enforcement powers and procedures as provided in Chapter lof this code. In addition to the general enforcement powers and procedures provided in Chapter 1of this code, the enforcement agency and enforcement official have the authority to utilize the following administrative remedies as may be necessary to enforce this chapter: A. Cease and Desist Orders. When the enforcement offidal finds that a discharge has taken place or is likely to take place in violafion of this chapter, the enforcement official may issue an order to cease and desist such discharge, practice, or operation likely to cause such discharge and direct that those persons not complying shall: 1. Comply with the applicable provisions and policies of this chapter. 2. Comply with a time schedule for compliance. 3. Take appropriate remedial or preventive action to prevent the violation from recurring. B. Notice to Clean, Test and/or Abate. Whenever the enforcement official finds any oil, earth, dirt, grass, weeds, dead trees, tin cans, rubbish, refuse, waste or any other material of any kind, in or upon the sidewalk abutting or adjoining any parcel of land, or upon any parcel of land or grounds, which may result in an increase in pollutants entering the city's storm water conveyance system or a nonstorm water discharge to the city's stomi water conveyance system, the enforcement official may issue orders and give written notice to remove same in any reasonable manner. The recipient of such notice shall undertake the activities as described in the notice. C. Stop Work Orders. Whenever any work is being done contrary to the provisions of this Ordinance, the enforcement official may order the work stopped by notice in writing served on any person engaged in performing or causing such work to be done, and any such person shall immediately stop such work until authorized by the enforcement official to proceed with the work. D. Permit or License Suspension or Revocation. Violations of this Ordinance may be grounds for permit or license suspension or revocation. E. Civil Penalties. Any person who violates any of the provisions of this chapter or who fails to implement a storm water monitoring plan, violates any cease and desist order or notice to clean and abate, or fails to adopt or implement a storm water pollution prevention plan as directed by the enforcement official shall be liable for a civil penalty not to exceed two thousand five hundred ($2,500) dollars for each day such a violafion exists. The violator shall be charged for the full costs of any investigafion, inspection, or monitoring survey which led to the detection of any such violation, for abatement costs, and for the reasonable costs of preparing and bringing legal acfion under this subsection. In addifion to any other applicable procedures, the enforcement agency may ufilize the lien procedures listed in Section15.12.150(F) to enforce the violator's liability. The violator may also be liable for compensatory damages for impairment, loss or destruction to water quality, wildlife, fish and aquatic life. (Ord. NS-394 § 2 (part), 1997) ' F. The enforcement oflicial shall take all appropriate legal steps to collect these obligations, including referral to the city attorney for commencement of a civil acfion to recover said funds. If collected as a lien, the enforcement official shall cause a notice of lien to be filed with the county recorder, inform the county auditor and county recorder of the amount of the obligafion, a descripfion of the real property upon which the lien is to be recovered, and the name of the agency to which the obligafion is to be paid. Upon payment in full, the enforcement official shall file a release of lien with the county recorder. (Ord. NS-394 § 2 (part), 1997 G. Environmental Code Enforcement Civil Penalties Fund. Civil penalties collected pursuant to this Chapter shall be deposited in the Environmental Code Enforcement Civil Penalties Fund as established by the City Manager for the enhancement of the City's code enforcement efforts, environmental public outreach or education, environmental improvement grants, and/or to reimburse City Departments for investigative costs and costs associated with the hearing process that are not paid by the responsible person or violator. Civil penalties deposited in this fund shall be appropriated and allocated in a manner determined by the City Manager. The City Auditor shall establish accounting procedures to ensure proper account identification, credit and collection. 15.12.170 Judicial enforcement. A. Criminal Penalties. Any person who violates any provision of this chapter or who fails to implement a storm water monitoring plan, violates any cease and desist order or notice to clean and abate, or fails to adopt or implement storm water pollution prevention plans or employee training programs as directed by the enforcement official shall be punished, upon conviction, by a fine not to exceed one thousand dollars for each day in which such violation occurs, or imprisonment in the San Diego County jail for a period not to exceed six months, or both. B. Injunction/Abatement of Public Nuisance. Whenever a discharge into the storm water conveyance system is in violation of the provisions of this chapter or otherwise threatens to cause a condition of contaminafion, pollution, or nuisance, the enforcement official may also cause the city to seek a petition to the Superior Court for the issuance of a preliminary or permanent injunction, or both, or an action to abate a public nuisance, as may be appropriate in restraining the confinuance of such discharge. C. Other Civil Action. Whenever a notice and order or hearing officer's decision is not complied with, the city attorney may, at the request of the enforcement official, initiate any appropriate civil action in a court of competent jurisdiction to enforce such notice and order and decision, including the recovery of any unpaid storm drain fees and/or civil penalfies provided herein. (Ord. NS-394 § 2 (part), 1997) 15.12.180 Violations deemed a public nuisance. in addition to the other civil and criminal penalties provided herein, any condifion caused or permitted to exist in violation of any of the provisions of this chapter is a threat to the public health, safety, and welfare and is declared and deemed a public nuisance, which may be summarily abated and/or restored as directed by the enforcement official in accordance with the procedures identified in Chapter 6.16. A civil action to abate, enjoin or otherwise compel the cessation of such nuisance may also be taken by the city, if necessary. The full cost of such abatement and restoration shall be borne by the owner of the property and the cost thereof shall be a lien upon and against the property in accordance with the procedures set forth in Secfion 15.12.150(F). 15.12.190 Remedies not exclusive. Remedies set forth in this chapter are not exclusive but are cumulative to all other civil and criminal penalfies provided by law, including, but not limited to, penalty provisions of the Federal Clean Water Act and/or the State Porter-Cologne Water Quality Control Act.

FACT SHEET FOR WATER QUALITY ORDER 99-08-DWQ STATE WATER RESOURCES CONTROL BOARD (SWRCB) 901 P STREET, SACRAMENTO, CALIFORNIA 95814 NATIONAL POLLUTANT DISCHARGE ELIMINATION SYSTEM (NPDES) GENERAL PERMIT FOR STORM WATER DISCHARGES ASSOCIATED WITH CONSTRUCTION ACTIVITY (GENERAL PERMIT) BACKGROUND In 1972, the Federal Water Pollution Control Act (also referred to as the Clean Water Act [CWA]) was amended to provide that the discharge of pollutants to waters of the United States from any point source is unlawful unless the discharge is in compliance with an NPDES permit. The 1987 amendments to the CWA added Section 402(p) which estabUshes a framework for regulating municipal and industrial storm water discharges tmder the NPDES Program. On November 16, 1990, the U.S. Environmental Protection Agency (USEPA) published final regulations that establish storm water permit application requirements for specified categories of industries. The regulations provide that discharges of storm water to waters ofthe United States from construction projects that encompass five (5) or more acres of soil disturbance are effectively prohibited unless the discharge is in compliance with an NPDES Permit. Regulations (Phase n Rule) that became final on December 8, 1999 expand the existing NPDES program to address storm water discharges from constraction sites that disturb land equal to or greater than one (1) acre and less than five (5) acres (small constraction activity). The regulations reqtiire that small constraction activity, other than those regulated vinder an individual or Regional Water Quality Control Board General Permit, must be permitted no later than March 10,2003. While federal regulations allow two permitting options for storm water discharges (individual permits and General Permits), the SWRCB has elected to adopt only one statewide General Permit at this time that will apply to all storm water discharges associated with constraction activity, except from those on Tribal Lands, in the Lake Tahoe Hydrologic Unit, and those performed by the California Department of Transportation (Caltrans). Constraction on Tribal Lands is regulated by an USEPA permit, the Lahontan Regional Water Control Board adopted a separate NPDES permit for the Lake Tahoe Hydrologic Unit, and the SWRCB adopted a separate NPDES permit for Caltrans projects. This General Pennit requires all dischargers where constraction activity disturbs one acre or more, to: 1. Develop and implement a Storm Water Pollution Prevention Plan (SWPPP) which specifies Best Management Practices (BMPs) that will prevent all constraction pollutants from contacting storm water and with the intent of keeping all products of erosion from moving off site into receiving waters. 2. Eliminate or reduce nonstorm water discharges to storm sewer systems and other waters of the nation. 3. Perform inspections of all BMPs. This General Permit shall be implemented and enforced by the nine Califomia Regional Water Quality Control Boards (RWQCBs). The General Permit accompanying this fact sheet regulates storm water runoff from constraction sites. Regulating many storm water discharges tmder one permit will greatly reduce the otherwise overwhelming administrative burden associated with permitting individual storm water discharges. Dischargers shall submit a Notice of Intent (NOI) to obtain coverage under this General Pennit. It is expected that as the storm water program develops, the RWQCBs may issue General Permits or individual permits containing more specific permit provisions. When this occurs, those dischargers will no longer be regulated by this General Permit. On August 19,1999, the State Water Resources Control Board (SWRCB) reissued the General Constraction Storm Water Pennit (Water Quality Order 99-08-DWQ referred to as "General Permit"). The San Francisco BayKeeper, Santa Monica BayKeeper, San Diego BayKeeper, and Orange Coast Keeper filed a petition for writ of mandate challenging the General Permit in the Superior Cotart, Coimty of Sacramento. The Court issued a judgment and writ of mandate on September 15,2000. The Court directed the SWRCB to modify the provisions of the General Permit to require permittees to implement specific sampling and analytical procedvires to determine whether Best Management Practices (BMPs) implemented on a constraction site are: (1) preventing fiirther impairment by sediment in storm waters discharged directly into waters listed as impaired for sediment or silt, and (2) preventing other pollutants, that are known or should be known by permittees to occur on constraction sites and that are not visually detectable in storm water discharges, from causing or contributing to exceedances of water quality objectives. The monitoring provisions in the General Permit have been modified pursuant to the court order. TYPES OF CONSTRUCTION ACTIVITY COVERED BY THIS GENERAL PERMIT Constraction activity subject to this General Permit includes clearing, grading, disturbances to the groimd such as stockpiling, or excavation that results in soil disturbances of at least one acre of total land area. Constraction activity that results Ln soil disturbances of less Uian one acre is subject to this General Permit if the constraction activity is part of a larger conmion plan of development that encompasses one or more acres of soil disturbance or if there is significant watar quality impairment resulting from the activity. Constraction activity does not include routine maintenance to maintain original line and grade, hydraulic capacity, or original purpose of the facility, nor does it include emergency constraction activities required to protect public health and safety. Dischargers should confirm with the local RWQCB whether or not a particular routine maintenance activity is subject to this General Pennit A constraction project which includes a dredge and/or fill discharge to any jurisdictional surface water (e.g., wetland, channel, pond, or marine water) will also need a CWA Section 404 permit from the U.S. Army Corps of Engineers and a CWA Section 401 Water Quality Certification from the RWQCB/SWRCB. Storm water discharges from dredge spoil placement which occurs outside of Corps jurisdiction (upland sites) and are part of constraction activity which disturbs one or more acres of land are covered by this general permit. Proponents of constraction projects which disturb one or more acres of land within the jurisdictional boundaries of a CWA Section 404 permit should contact the local RWQCB to determine the applicability of this permit to the project. NOTIFICATION REOUIREMENTS It is the responsibility of the landowner to obtain coverage under this General Pennit prior to commencement of constraction activities. To obtain coverage, the landowner must file an NOI with a vicinity map and the appropriate fee with the SWRCB. In addition, coverage under this permit shall not occur until the applicant develops an adequate SWPPP for the project. Section A ofthe General Pennit outlines the required contents of a SWPPP. For proposed constraction activity on easements or on nearby property by agreement or permission, the entity responsible for the constraction activity shall file an NOI and filing fee and shall be responsible for development ofthe SWPPP, all of which must occur prior to commencement of constraction activities. A separate NOI shall be submitted to the SWRCB for each constraction site. Owners of new constraction shall file an NOI prior to the commencement of constraction. Owners ofan ongoing constraction site that is covered under the previous General Constraction Permit (WQ Order NO.92-08-DWQ) (1) shall continue to implement their existing SWPPP and monitoring program and (2) shall implement any necessary revisions to their SWPPP in a timely maimer but in no case later than 90-calender days from adoption of this General Permit in accordance with Section A of this General Permit. The NOI requirements ofthe General Permit are intended to establish a mechanism which can be used to clearly identify the responsible parties, locations, and scope of operations of dischargers covered by the General Permit and to document the discharger's knowledge ofthe requirements for a SWPPP. The NOI must be sent to the following address: State Water Resources Confrol Board Division of Water Quality Storm Water Permit Unit P.O. Box 1977 Sacramento, CA 95812-1977 The total aimual fee is the current base fee plus applicable surcharges. When constraction is complete or ownership has been fransferred, dischargers shall file a Notice of Termination with the RWQCB certifying that all State and local requirements have been met in accordance with Special Provisions for Constraction Activity, C.7, ofthe General Pemiit. Dischargers who fail to obtain coverage under this General Pennit for storm water discharges to surface waters will be in violation of Ae CWA and the California Water Code. CONSTRUCTION ACTIVITY NOT COVERED BY THIS GENERAL PERMIT This General Pennit does not apply to storm water discharges from (1) those areas on Tribal Lands; (2) the Lake Tahoe Hycfrologic Unit; (3) constraction under one acre, unless part of a larger common plan of development or sale; (4) projects covered by an individual NPDES Permit for storm water discharges associated with constraction activitjr, and (5) landfill constraction that is subject to the general industrial pennit. Storm wata- discharges in the Lake Tahoe Hydrologic Unit are regulated by a separate pennit(s) adopted by the CaHfomia Regional Water Quality Confrol Board, Lahontan Region (LRWQCB). USEPA regulates storm water discharges on Tribal Lands. Pennit appUcations for storm water discharges fhat will be conducted in the Lake Tahoe Hydrologic Unit must be submitted directly to the LRWQCB. DESCRIPTION OF GENERAL PERMIT CONDITIONS The following is a brief description ofthe major provisions of the General Pennit and the basis for the General Permit. Prohibitions This General Permit authorizes the discharge of storm water to surface waters from constraction activities that result in the disturbance of one or more acres of land. It prohibits the discharge of materials other than storm water and authorized non-storm water discharges and all discharges which contain a hazardous substance in excess of reportable quantities established at 40 Code of Federal Regulations (CFR) 117.3 or 40 CFR 302.4 unless a separate NPDES Permit has been issued to regulate those discharges. In addition, this General Pennit contains provisions that uphold discharge prohibitions contained in water quality confrol plans, as implemented through the nine RWQCBs. Effluent Limitations Pennits for storm water discharges associated with constraction activity shall meet all applicable provisions of Sections 301 and 402 of the CWA. These provisions require confrols of pollutant discharges that utilize best available technology economically achievable (BAT) and best conventional pollutant confrol technology (BCT) to reduce pollutants and any more stringent confrols necessary to meet water quality standards. It is not feasible at this time for the SWRCB to establish numeric effluent limitations. The reasons why it is not feasible to establish numeric effluent limitations are discussed in detail in SWRCB Order Nos. WQ 91-03 and WQ 91-04. Therefore, the effluent limitations contained in this General Permit are narrative and include the requfrement to implement appropriate BMPs. The BMPs shall primarily emphasize source confrols such as erosion confrol and pollution prevention methods. The discharger shall also install stractural confrols, as necessary, such as sediment confrol which will constitute BAT and BCT and will achieve compliance with water quality standards. The narrative effluent limitations constitute compliance with the requirements ofthe CWA. Elimination or reduction of nonstorm water discharges is a major goal of this General Permit. Nonstorm water discharges include a wide variety of sources, including improper dumping, spills, or leakage from storage tanks or fransfer areas. Nonstorm water discharges may contribute a significant pollutant load to receiving waters. Measures to confrol spills, leakage, and dumping and to prevent illicit connections during constraction shall be addressed through stractural as well as non-stractural BMPs. This General Permit prohibits the discharge of materials other than storm water and authorized nonstorm water discharges. It is recognized that certain nonstorm water discharges may be necessary for the completion of constraction projects. Such discharges include, but are not limited to irrigation of vegetative erosion confrol measures, pipe flushing and testing, sfreet cleaning, and dewatering. Such discharges are allowed by this General Permit provided they are not relied upon to clean up failed or inadequate constraction or post-constraction BMPs designed to keep materials onsite. These authorized nonstorm water discharges shall (1) be infeasible to eliminate, (2) comply with BMPs as described in the SWPPP, and (3) not cause or contribute to a violation of water quality standards. Additionally, these discharges may be required to be permitted by the local RWQCB (e.g., some RWQCBs have adopted General Permits for dewatering discharges). This General Pennit is performance-based to the extent that it prohibits the discharge of storm water that causes or threatens to cause pollution, contamination, or nuisance; but it also allows the owner/developer to determine the most economical, effective, and possibly innovative BMPs. The requfrements of this General Permit are intended to be implemented on a year-round basis, not just during the part of the year when there is a high probability of a precipitation event which results in storm water runoff. The permit should be implemented at the appropriate level and in a proactive manner during all seasons while constraction is ongoing. Weather and storm predictions or weather information concerning the 10-year, 6-hour storm event and mean annual rainfall can be obtained by calling the Westem Regional Climate Center at 775-674-7010 or via the intemet at www.wrcc.dri.edu/precip.html and/or www.wrcc.dri.edu/pcpnfreq.html. Receiving Water Limitations Language The receiving water limitations language is fundamentally different from the language adopted in the SWRCB General Industrial Activities Storm Water Permit on April 17,1997. Constraction related activities which cause or contribute to an exceedance of water quality standards must be corrected immediately and cannot wait for the RWQCB to approve a plan of action to correct. The dynamic nature of constraction activity allows the discharger the ability to more quickly identify and correct the source of the exceedances. Therefore, the owner is requfred to take immediate corrective action and to provide a report to the appropriate RWQCB within 14-calendar days of fhe violation describing the corrective action. Storm Water Pollution Prevention Plan (SWPPP) This General Permit requfres development and implementation of a SWPPP. This document emphasizes the use of appropriately selected, correctly installed and maintained pollution reduction BMPs. This approach provides the flexibility necessary to establish BMPs which can effectively address source confrol of pollutants during changing construction activities. All dischargers shall prepare and implement a SWPPP prior to disturbing a site. The SWPPP must be implemented at the appropriate level to protect water quality at all times througout the life ofthe project. Nonstorm water BMPs must be implemented year round. The SWPPP shall remain on the site while the site is under constraction, commencing with the initial mobilization and ending wifh the termination of coverage under the pennit. The SWPPP has two major objectives: (1) to help identify the sources of sediment and other pollutants that affect the quality of storm water discharges and (2) to describe and ensure the implementation of BMPs to reduce or eliminate sediment and other pollutants in storm water as well as nonstorm water discharges. The SWPPP shall include BMPs which address source confrol and, if necessary, shall also include BMPs which address pollutant confrol. Required elements of a SWPPP include: (1) site description addressing the elements and characteristics specific to the site, (2) descriptions of BMPs for erosion and sediment confrols, (3) BMPs for constraction waste handling and disposal, (4) implementation of approved local plans, (5) proposed post-constraction confrols, including description of local post-constraction erosion and sediment confrol requfrements, and (6) nonstorm water management. To ensure that the preparation, implementation, and oversight of the SWPPP is sufficient for effective pollution prevention, individuals responsible for creating, revising, overseeing, and implementing the SWPPP should participate in applicable fraining programs and document such fraimng fri the SWPPP. SWPPPs are reports that are available to the public under Section 308(b) of the CWA and will be made available by the RWQCB upon request. Monitoring Program Another major feature of the General Pennit is the development and implementation of a monitoring program. All dischargers are requfred to conduct inspections ofthe constraction site prior to anticipated storm events and after actual storm events. During extended storm events, inspections must be made during each 24-hour period. The goals of these inspections are (1) to identify areas contributing to a storm water discharge; (2) to evaluate whether measures to reduce pollutant loadings identified in the SWPPP are adequate and properly installed and functioning in accordance with the terms ofthe General Pennit; and (3) whether additional confrol practices or corrective maintenance activities are needed. Equipment, materials, and workers must be available for rapid response to failures and emergencies. All corrective maintenance to BMPs shall be performed as soon as possible, depending upon worker safety. Each discharger shall certify aimually that the constraction activities are in compliance with the requirements of this General Pennit. Dischargers who cannot certify annual compliance shall notify the appropriate RWQCB. A well-developed monitoring program will provide a good method for checking the effectiveness of the SWPPP. Retention of Records The discharger is required to retain records of all monitoring information, copies of all reports requfred by this General Permit, and records of all data used to complete the NOI for all constraction activities to be covered by the General Pennit for a period of at least three years from the date generated. This period may be extended by request of the SWRCB and/or RWQCB. With the exception of reporting noncompliance to the appropriate RWQCB, dischargers are not requfred to submit the records, except upon specific request by the RWQCB. STATE WATER RESOURCES CONTROL BOARD (SWRCB ) ORDER NO. 99 - 08 - DWQ NATIONAL POLLUTANT DISCHARGE ELIMINATION SYSTEM (NPDES) GENERAL PERMTF NO. CAS000002 WASTE DISCHARGE REQUIREMENTS (WDRS) FOR DISCHARGES OF STORM WATER RUNOFF ASSOCIATED WITH CONSTRUCTION ACTIVITY The State Water Resources Confrol Board finds that: 1. Federal regulations for confrolling pollutants in storm water runoff discharges were promulgated by the U.S. Envfronmental Protection Agency (USEPA) on November 16, 1990 (40 Code of Federal Regulations (CFR) Parts 122,123, and 124). The regulations require discharges of storm water to surface waters associated with constraction activity including clearing, grading, and excavation activities (except operations that result in disturbance of less than five acres of total land area and which are not part of a larger common plan of development or sale) to obtain an NPDES permit and to implement Best Available Technology Economically Achievable (BAT) and Best Conventional Pollutant Confrol Technology (BCT) to reduce or eliminate storm water pollution. On December 8,1999 federal regulations promulgated by USEPA (40CFR Parts 9,122,123, and 124) expanded the NPDES storm water program to include storm water discharges from municipal separate storm sewer systems (MS4s) and constraction sites that were smaller than those previously included in the program. Federal regulation 40 CFR § 122.26(b)(15) defines small constraction activity as including clearing, grading, and excavating that result in land disturbance of equal to or greater than one acre or less than five acres or is part of a larger common plan of development or sale. Permit applications for small constraction activities are due by March 10,2003. 2. This General Pennit regulates pollutants in discharges of storm water associated with constraction activity (storm water discharges) to surface waters, except from those areas on Tribal Lands; Lake Tahoe Hydrologic Unit; constraction projects which disturb less than one acre, unless part of a larger common plan of development or sale; and storm water discharges which are detennined ineligible for coverage under this General Permit by the California Regional Water Quality Confrol Boards (RWQCBs). Attachment 1 contains addresses and telephone numbers of each RWQCB office. 3. This General Permit does not preempt or supersede the authority of local storm water management agencies to prohibit, restrict, or confrol storm water discharges to separate storm sewer systems or other watercourses within thefr jurisdiction, as allowed by State and Federal law. 4. To obtain authorization for proposed storm water discharges to surface waters, pursuant to this General Permit, the landowner (discharger) must submit a Notice of Intent (NOI) with a vicinity map and the appropriate fee to fhe SWRCB prior to commencement of constraction activities. In addition, coverage under this General Permit shall not occur until the applicant develops a Storm Water Pollution Prevention Plan (SWPPP) in accordance with the requfrements ofSection A oftiiis permit for the project. For proposed constraction activity conducted on easements or on nearby property by agreement or pennission, or by an owner or lessee of a mineral estate (oil, gas, geothermal, aggregate, precious metals, and/or industrial minerals) entitled to conduct the activities, the entity responsible for the constraction activity must submit the NOI and filing fee and shall be responsible for development of the SWPPP. 5. If an individual NPDES Permit is issued to a discharger otherwise subject to this General Permit or if an altemative General Permit is subsequentiy adopted which covers storm watCT discharges regulated by this General Permit, the applicability of this General Permit to such discharges is automatically terminated on the effective date of the individual permit or the date of approval for coverage under the subsequent General Permit. 6. This action to adopt an NPDES permit is exempt from the provisions of the California Environmental Quality Act (Public Resources Code Section 21100, et seq.) in accordance with section 13389 ofthe California Water Code. 7. The SWRCB adopted the California Ocean Plan, and the RWQCBs have adopted and the SWRCB has approved Water Quality Confrol Plans (Basin Plans). Dischargers regulated by this General Permit must comply with the water quality standards in these Basin Plans and subsequent amendments thereto. 8. The SWRCB finds storm water discharges associated wifh constraction activity to be a potential significant sources of pollutants. Furthermore, the SWRCB finds that storm water discharges associated with constraction activities have the reasonable potential to cause or contribute to an excursion above water quality standards for sediment in the water bodies listed in Attachment 3 to this permit. 9. It is not feasible at this time to establish numeric effluent limitations for pollutants in storm water discharges from constraction activities. Instead, the provisions of this General Permit requfre implementation of Best Management Practices (BMPs) to confrol and abate the discharge of pollutants in storm water discharges. 10. Discharges of non-storm water may be necessary for the completion of certain constraction projects. Such discharges include, but are not limited to: irrigation of vegetative erosion confrol measures, pipe flushing and testing, sfreet cleaning, and dewatering. Such discharges are authorized by this General Permit as long as they (a) do comply with Section A.9 of this General Permit, (b) do not cause or contribute to violation of any water quality standard, (c) do not violate any other provision of this General Permit, (d) do not requfre a non-stonn water permit as issued by some RWQCBs, and (e) are not prohibited by a Basin Plan. If a non-storm water discharge is subject to a separate permit adopted by a RWQCB, the discharge must additionally be authorized by the RWQCB permit. 11. Following adoption of this General Permit, fhe RWQCBs shall enforce the provisions herein including the monitoring and reporting requirements. 12. Following public notice in accordance with State and Federal laws and regulations, fhe SWRCB in a public meeting on June 8,1998, heard and considered all comments. The SWRCB has prepared written responses to all significant comments. 13. This Order is an NPDES permit in compliance with section 402 of the Clean Water Act (CWA) and shall take effect upon adoption by the SWRCB provided the Regional Adminisfrator of the USEPA has no objection. If the USEPA Regional Adminisfrator objects to its issuance, the General Permit shall not become effective until such objection is withdrawn. 14. This General Permit does not authorize discharges of fill or dredged material regulated by the U.S. Army Corps of Engineers under CWA section 404 and does not constitute a waiver of water quality certification under CWA section 401. 15 The Monitoring Program and Reporting Requfrements are modified in compliance with a judgment in the case of San Francisco BayKeeper, et al. v. State Water Resources Confrol Board. The modifications include sampling and analysis requfrements for dfrect discharges of sediment to waters impafred due to sediment and for pollutants that are not visually detectable in runoff that may cause or contribute to an exceedance of water quality objectives. 16 Storm water discharges associated with industrial activity that are owned or operated by municipalities serving populations less than 100,000 people are no longer exempt from fhe need to apply for or obtain a storm water discharge permit. A temporary exemption, which was later extended by USEPA, was provided under section 1068(c) of the Intermodal Surface Transportation and Efficiency Act (ISTEA) of 1991. Federal regulation 40 CFR § 122.26(e)(l)(ii) requires the above municipalities to submit permit application by March 10, 2003. 17 This permit may be reopened and modified to include different monitoring requfrements for small constraction activity than for consfruction activity over five (5) acres. IT IS HEREBY ORDERED that all dischargers who file an NOI indicating their intention to be regulated under the provisions of this General Permit shall comply witii the following: A. DISCHARGE PROHBITIONS: 1. Authorization pursuant to this General Permit does not constitute an exemption to applicable discharge prohibitions prescribed in Basin Plans, as implemented by the rnne RWQCBs. 2. Discharges of material other than storm water which are not otherwise authorized by an NPDES permit to a separate storm sewer system (MS4) or waters of the nation are prohibited, except as allowed in Special Provisions for Constraction Activity, C.3. 3. Storm water discharges shall not cause or threaten to cause pollution, contamination, or nuisance. 4. Storm water discharges regulated by this General Pennit shall not contain a hazardous substance equal to or in excess of a reportable quantity listed in 40 CFR Part 117 and/or 40 CFR Part 302. B. RECEIVING WATER LIMITATIONS: 1. Storm water discharges and authorized nonstorm water discharges to any surface or ground water shall not adversely impact human health or the envfronment. 2. The SWPPP developed for fhe constraction activity covered by this General Permit shall be designed and implemented such that storm water discharges and authorized nonstorm water discharges shall not cause or contribute to an exceedance of any applicable wata- quality standards contained in a Statewide Water Quality Confrol Plan and/or the applicable RWQCB's Basin Plan. 3.

Identify a sampling and analysis sfrategy and sampling schedule for discharges from constraction activity which discharge directly into water bodies listed on Attachment 3. (Clean Water Act Section 303(d) [303(d)] Water Bodies listed for Sedimentation). f. For all constraction activity, identify a sampling and analysis sfrategy and sampling schedule for discharges that have been discovered through visual monitoring to be potentially contaminated by pollutants not visually detectable in the runoff. 2. Implementation Schedule a. For constraction activity commencing on or after adoption of this General Permit, the SWPPP shall be developed prior to the start of soil-disturbing activity in accordance with this Section and shall be implemented concurrentiy with commencement of soil-disturbing activities. b. Existing permittees engaging in constraction activities covered under fhe terms of tiie previous General Constraction Pennit SWPPP (WQ Order No.92-08-DWQ) shall continue to impleinent their existing SWPPP and shall implement any necessary revisions to thefr SWPPP in accordance with this Section of the General Permit in a timely manner, but in no case more than 90-calender days from the date of adoption of this General Permit. c. For ongoing constraction activity involving a change of ownership of property, the new owner shall review the existing SWPPP and amend if necessary, or develop a new SWPPP within 45-calender days. d. Existing permittees shall revise their SWPPP in accordance with the sampling and analysis modifications prior to August 1,2001. For ongoing constraction activity involving a change of ownership the new owner shall review the existing SWPPP and amend the sampling and analysis sfrategy, if requfred, within 45 days. For constiuction activity commencing after the date of adoption, the SWPPP shall be developed in accordance with the modification language adopted. 3. Availability The SWPPP shall remain onthe constraction site while the site is under constriction during working hours, commencing with the initial constraction activity and ending with termination of coverage under the General Pennit. Requfred Changes a. The discharger shall amend the SWPPP whenever there is a change in constraction or operations which may affect the discharge of pollutants to surface waters, ground waters, or a municipal separate storm sewer system (MS4). The SWPPP shall also be amended if the discharger violates any condition of this General Permit or has not achieved the general objective of reducing or eliminating pollutants in storm water discharges. If the RWQCB determines that the discharger is in violation of this General Permit, the SWPPP shall be amended and implemented in a timely manner, but in no case more than 14-calendar days after notification by the RWQCB. All amendments should be dated and directly attached to tiie SWPPP. b. The RWQCB or local agency with the concurrence of the RWQCB may requfre the discharger to amend the SWPPP.

Where relevant drainage areas are too large to depict on tiie map, map notes or inserts illusfrating the upsfream drainage areas are sufficient. (c) Temporary on-site drainages to carry concenfrated flow shall be selected to comply with local ordinances, to confrol erosion, to retum flows to thefr natural drainage courses, and to prevent damage to downsfream properties. 3. Information presented in the SWPPP may be represented either by narrative or by graphics. Where possible, narrative descriptions should be plan notes. Narrative descriptions which do not lend themselves to plan notes can be contained in a separate document which must be referenced on the plan. b. Pollutant Source and BMP Identification The SWPPP shall include a description of potential sources which are likely to add pollutants to storm water discharges or which may result in nonstorm water discharges from the constraction site. Discharges originating from off-site which flow across or through areas disturbed by constraction that may contain pollutants should be reported to tiie RWQCB. 11 The SWPPP shall: (1) Show drainage pattems and slopes anticipated after major grading activities are completed. Runoff from off-site areas should be prevented from flowing through areas that have been disturbed by constraction unless appropriate conveyance systems are in place.

Samples shall be taken should visual monitoring indicate that there has been a breach, malfunction, leakage, or spill from a BMP which could result in the discharge in storm water of pollutants that would not be visually detectable, or if storm water comes into contact with soil amendments or other exposed materials or contamination and is allowed to be discharged. Describe the sampling procedure, location, and rationale for obtaining the uncontaminated sample of storm water. Additional Information (1) The SWPPP shall include a narrative description of pollutant sources and BMPs that cannot be adequately communicated or identified on the site map. In addition, a narrative description of preconstraction confrol practices (if any) to reduce sediment and other pollutants in storm water discharges shall be included.

(6) The SWPPP shall list the name and telephone number of the qualified person(s) who have been assigned responsibility for prestorm, poststorm, and storm event BMP inspections; and the qualified person(s) assigned responsibility to ensure full compUance with the permit and implementation of all elements of the SWPPP, including the preparation of the annual compliance evaluation and the elimination of all unauthorized discharges. Erosion Confrol Erosion confrol, also referred to as "soil stabilization" is the most effective way to retain soil and sediment on the constraction site. The most efficient way to address erosion confrol is to preserve existing vegetation where feasible, to limit disturbance, and to stabilize and revegetate disturbed areas as soon as possible after grading or constraction. Particular attention must be paid to large mass-graded sites where the potential for soil exposure to the erosive effects of rainfall and wind is great. Mass graded constraction sites may be exposed for several years while the project is being built out. Thus, there is potential for significant sediment discharge from the site to surface waters. At a ininimum, the discharger/operator must implement an effective combination of erosion and sediment confrol on all disturbed areas during the rainy season. These disturbed areas include rou^ graded roadways, slopes, and building pads. Until permanent vegetation is established, soil cover is the most cost-effective and expeditious method to protect soil particles from detachment and fransport by rainfall. Temporary soil stabilization can be the single-most important factor in reducing erosion at constraction sites. The discharger shall consider measures such as: covering with mulch, temporary seeding, soil stabilizers, binders, fiber rolls or blankets, temporary vegetation, permanent seeding, and a variety of other measures. The SWPPP shall include a description of the erosion confrol practices, including a time schedule, to be implemented during constraction to minimize erosion on disturbed areas of a constraction site. The discharger must consider the fiill range of erosion confrol BMPs. The discharger must consider any additional site-specific and seasonal conditions when selecting and implementing appropriate BMPs. The above listed erosion control measures are examples of what should be considered and are not exclusive of new or innovative approaches currentiy available or being developed. 14 The SWPPP shall include: (1) An outiine of the areas of vegetative soil cover or native vegetation onsite which will remain undisturbed during the constraction project (2) An outline of all areas of soil disturbance including cut or fill areas which will be stabilized during the rainy season by temporary or permanent erosion confrol measures, such as seeding, mulch, or blankets, etc. (3) An outline ofthe areas of soil disturbance, cut, or fill which will be left exposed during any part ofthe rainy season, representing areas of potential soil erosion where sediment confrol BMPs are requfred to be used during constraction. (4) A proposed schedule for the implementation of erosion confrol measures. The SWPPP shall include a description of the BMPs and confrol practices to be used for both temporary and permanent erosion confrol measures. The SWPPP shall include a description of the BMPs to reduce wind erosion at all times, with particular attention paid to stock-piled materials. 7. Stabilization (1) All disturbed areas of the constraction site must be stabilized. Final stabilization for the purposes of submitting a NOT is satisfied when: -AU soil distiirbing activities are completed AND EITHER OF THE TWO FOLLOWING CRITERL\. ARE MET: -A uniform vegetative cover with 70 percent coverage has been established OR: -equivalent stabilization measures have been employed. These measures include the use of such BMPs as blankets, reinforced chaimel liners, soil cement, fiber matrices, geotextiles, or other erosion resistant soil coverings or freatments. (2) Where background native vegetation covers less than 100 percent of the surface, such as in arid areas, the 70 percent coverage criteria is adjusted as follows: If the native vegetation covers 50 percent of fhe ground surface, 70 percent of 50 percent (.70 X .50=.35) would requfre 35 percent total uniform surface coverage. 15 8. Sediment Confrol The SWPPP shall include a description or illusfration of BMPs which wiU be implemented to prevent a net increase of sediment load in storm water discharge relative to preconstraction levels. Sediment confrol BMPs are requfred at appropriate locations along the site perimeter and at all operational intemal inlets to the storm drain system at all times during the rainy season. Sediment confrol practices may include filtration devices and barriers (such as fiber rolls, silt fence, straw bale barriers, and gravel inlet filters) and/or settling devices (such as sediment fraps or basins). Effective filfration devices, barriers, and settling devices shall be selected, installed and maintained properly. A proposed schedule for deployment of sediment confrol BMPs shall be included in the SWPPP. These are the most basic measures to prevent sediment from leaving the project site and moving into receiving waters. Limited exemptions may be authorized by the RWQCB when work on active areas precludes the use of sediment confrol BMPs temporarily. Under these conditions, the SWPPP must describe a plan to estabUsh perimeter confrols prior to the onset of rain. During the nom-ainy season, the discharger is responsible for ensuring that adequate sediment confrol materials are available to confrol sediment discharges at the downgrade perimeter and operational inlets in the event of a predicted storm. The discharger shall consider a full range of sediment confrols, in addition to the confrols Usted above, such as sfraw bale dikes, earth dikes, brash barriers, drainage swales, check dams, subsurface drain, sandbag dikes, fiber rolls, or other confrols. At a minimum, the discharger/operator must implement an effective combination of erosion and sediment confrol on all disturbed areas during the rainy season. If the discharger chooses to rely on sediment basins for freatment purposes, sediment basins shall, at a minimum, be designed and maintained as follows: Option 1: Pursuant to local ordinance for sediment basin design and maintenance, provided that the design efficiency is as protective or more protective of water quality than Option 3. OR Option 2: Sediment basin(s), as measured from the bottom of the basin to the principal outiet, shall have at least a capacity equivalent to 3,600 cubic feet of storage per acre draining into the sediment basin. The length of the basin shall be more than twice the width of the basin. The length is determined by measuring the distance between the inlet and the outiet; and the depth must not be less than three feet nor greater than five feet for safety reasons and for maximum efficiency. 16 OR Option 3: Sediment basin(s) shall be designed using the standard equation: As=1.2Q/Vs Where: As is the minimum surface area for frapping soil particles of a certain size; Vs is the settiing velocity ofthe design particle size chosen; and Q=C x I x A where Q is the discharge rate measured in cubic feet per second; C is the runoff coefficient; I is the precipitation intensity for the 10-year, 6-hour rain event and A is the area draining into the sediment basin in acres. The design particle size shall be the smallest soil grain size determined by wet sieve analysis, or the fine silt sized (0.01mm) particle, and the Vs used shall be 100 percent of the calculated settling velocity. The length is detemiined by measuring the distance between the inlet and the outiet; the length shall be more than twice the dimension as the width; the depth shall not be less than three feet nor greater than five feet for safety reasons and for maximum efficiency (two feet of storage, two feet of capacity). The basin(s) shall be located on the site where it can be maintained on a year-round basis and shall be maintained on a schedule to retain the two feet of capacity; OR Option 4: The use of an equivalent surface area design or equation, provided that the design efficiency is as protective or more protective of water quality than Option 3. A sediment basin shall have a means for dewatering within 7-calendar days following a storm event Sediment basins may be fenced if safety (worker or public) is a concem. The outflow from a sediment basin that discharges into a natural drainage shall be provided with outlet protection to prevent erosion and scour of the embankment and channel. The discharger must consider any additional site-specific and seasonal conditions when selecting and designing sediment confrol BMPs. The above listed sediment confrol measures are examples of what should be considered and are not exclusive of new or innovative approaches currentiy available or being developed. The SWPPP shall include a description of the BMPs to reduce the fracking of sediment onto public or private roads at all times. These public and private roads shall be inspected and cleaned as necessary. Road cleaning BMPs shall be discussed in the 17 SWPPP and wiU not rely on the washing of accumulated sediment or silt into the storm drain system. 9. Non-Storm Water Management Describe all non-storm water discharges to receiving waters that are proposed for the constraction project. Non-stonn water discharges should be eliminated or reduced to the extent feasible. Include the locations of such discharges and descriptions of all BMPs designed for the confrol of pollutants in such discharges. Onetime discharges shall be monitored during the time that such discharges are occurring. A qualified person should be assigned the responsibility for ensuring that no materials other than storm water are discharged in quantities which will have an adverse effect on receiving waters or storm drain systems (consistent with BAT/BCT), and the name and contact number of that person should be included in the SWPPP document. Discharging sediment-laden water which will cause or contribute to an exceedance of the applicable RWQCB's Basin Plan from a dewatering site or sediment basin into any receiving water or storm drain without filfration or equivalent freatment is prohibited. 10. Post-Constraction Storm Water Management The SWPPP shall include descriptions ofthe BMPs to reduce pollutants in storm water discharges after all constraction phases have been completed at the site (Post- Constraction BMPs). Post-Constraction BMPs include the minimization of land disturbance, the minimization of impervious surfaces, freatment of storm water runoff using infilfration, detention/retention, biofilter BMPs, use of efficient irrigation systems, ensuring that interior drains are not coimected to a storm sewer system, and appropriately designed and constracted energy dissipation devices. These must be consistent with all local post-constraction storm water management requfrements, policies, and guidelines. The discharger must consider site-specific and seasonal conditions when designing the confrol practices. Operation and maintenance of confrol practices after constraction is completed shall be addressed, including short-and long-term funding sources and the responsible party. 11. Maintenance. Inspection, and Repafr The SWPPP shall include a discussion ofthe program to inspect and maintain all BMPs as identified in the site plan or other narrative documents througout the entire duration of the project. A qualified person will be assigned the responsibility to conduct inspections. The name and telephone number of that person shall be listed in the SWPPP document. Inspections will be perfonned before and after storm events and once each 24-hour period during extended storm events to identify BMP effectiveness and implement repafrs or design changes as soon as feasible depending upon field conditions. Equipment, materials, and workers must be available for rapid response to failures and 18 emergencies. All corrective maintenance to BMPs shall be performed as soon as possible after the conclusion of each storm depending upon worker safety. For each inspection requfred above, the discharger shall complete an inspection checklist. At a minimum, an inspection checklist shall include: a. Inspection date. b. Weather information: best estimate of begiiming of storm event, duration of event, time elapsed since last storm, and approximate amount of rainfall (inches). c. A description of any inadequate BMPs. d. If it is possible to safely access during inclement weather, list observations of all BMPs: erosion confrols, sediment confrols, chemical and waste confrols, and non-storm water confrols. Otherwise, list result of visual inspection at relevant outfall, discharge point, or downsfream location and projected requfred maintenance activities. e. Corrective actions required, including any changes to SWPPP necessaiy and implementation dates. f Inspectors name, titie, and signature. The dischargers shall prepare thefr inspection checklists using the inspection checklist form provided by the SWRCB or RWQCB or on forms that contain the equivalent information. 12. Training Individuals responsible for SWPPP preparation, implementation, and permit compliance shall be appropriately frained, and the SWPPP shall document all fraining. This includes those personnel responsible for installation, inspection, maintenance, and repafr of BMPs. Those responsible for overseeing, revising, and amending the SWPPP shall also document their fraining. Training should be both formal and informal, occur on an ongoing basis when it is appropriate and convenient, and should include fraining/workshops offered by the SWRCB, RWQCB, or other locally recognized agencies or professional organizations. 13. List of Confractors/Subconfractors The SWPPP shall include a list of names of all confractors, (or subconfractors) and individuals responsible for implementation ofthe SWPPP. This list should include telephone numbers and addresses. Specific areas of responsibility of each subconfractor and emergency contact numbers should also be included. 19 14. Otiier Plans This SWPPP may incorporate by reference the appropriate elements ofother plans required by local. State, or Federal agencies. A copy of any requfrements incorporated by reference shall be kept at the constraction site. 15. Public Access The SWPPP shall be provided, upon request, to the RWQCB. The SWPPP is considered a report that shall be available to the pubUc by the RWQCB under section 308(b) of tiie Clean Water Act. 16. Preparer Certification The SWPPP and each amendment shall be signed by the landowner (discharger) or his representative and include the date of initial preparation and the date of each amendment. SECTION B: MONITORING PROGRAM AND REPORTING REQUIREMENTS 1. Required Changes The RWQCB may require the discharger to conduct additional site inspections, to submit reports and certifications, or perform sampling and analysis. 2. Implementation a. The requfrements of this Section shall be implemented at the time of commencement of constraction activity (see also Section A. 2. Implementation Schedule). The discharger is responsible for implementing these requfrements until constraction activity is complete and fhe site is stabilized. b. For ongoing constraction activity mvolving a change in ownership of property covered by this General Permit, the new owner must complete a NOI and implement the requfrements of tiiis Section concurrent with the change of ownership. For changes of information, the owner must foUow instractions in C. 7. Special Provisions for Constraction Activity of the General Permit 3. Site Inspections Qualified personnel shall conduct inspections ofthe constraction site prior to anticipated storm events, during extended storm events, and after actual storm events to identify areas contributing to a discharge of storm water associated with constraction activity. The 20 name(s) and contact number(s) ofthe assigned inspectioii personnel shall be listed in the SWPPP. Pre-storm inspections are to ensure fhat BMPs are properly instaUed and maintained; post-storm inspections are to assure that the BMPs have functioned adequately. Durfrig extended storm events, inspections shall be requfred each 24-hour period. Best Management Practices (BMPs) shall be evaluated for adequacy and proper implementation and whether additional BMPs are requfred in accordance with the terms ofthe General Permit (see language in Section A. 11. Maintenance, Inspection, and Repafr). Implementation of nonstorm water discharge BMPs shall be verified and thefr effectiveness evaluated. One time discharges of non-storm water shall be inspecfed when such discharges occur. Compliance Certification Each discharger or qualified assigned persoimel listed by name and contact number in the SWPPP must certify annually that construction activities are in compliance with the requfrements of this General Pennit and the SWPPP. This Certification shall be based upon the site inspections requfred in Item 3 of this Section. The certification must be completed by July 1 of each year. Noncompliance Reporting Dischargers who cannot certify compliance, in accordance with Item 4 of this Section and/or who have had other instances of noncompliance excluding exceedances of water quality standards as defined in section B. 3. Receiving Water Limitations Language, shall notify the appropriate RWQCB within 30 days. Corrective measures should be implemented immediately following discovery that water quality sfandards were exceeded. The notifications shall identify the noncompliance event, including an initial assessment of any impact caused by the event; describe the actions necessary to achieve compliance; and include a time schedule subject to fhe modifications by the RWQCB indicating when compliance will be achieved. Noncompliance notifications must be submitted within 30-calendar days of identification of noncompliance. Monitoring Records Records of all inspections, compliance certifications, and noncompliance reporting must be retained for a period of at least three years from the date generated. With the exception of noncompliance reporting, dischargers are not required to submit these records. Monitoring Program for Sedimentation/Siltation Dischargers of storm water associated with constraction activity that dfrectiy enters a water body listed in Attachment 3 shall conduct a sampling and analysis program for the pollutants (sedimentation/siltation or turbidity) causing the impairment The discharger shall monitor for the applicable parameter. If the water body is listed for sedimentation or 21 siltation, samples should be analyzed for Settieable SoUds (ml/1) and Total Suspended SoUds (mg/1). Altematively or in addition, samples may be analyzed for suspended sediment concenfration according to ASTM D3977-97, If the water body is Usted for turbidity, samples should be analyzed for turbidity (NTU), Discharges tiiat flow tiirough tiibutaries that are not Usted in Attachment 3 or tiiat flow into Municipal Separate Storm Sewer Systems (MS4) are not subject to these sampling and analysis requfrements. The sampling and analysis parameters and procedures must be designed to determine whether the BMPs installed and maintained prevent discharges of sediment from contributing to impairment in receiving waters. Samples shall be coUected during fhe ffrst two hours of discharge from rain events which result in a dfrect discharge to any water body Usted in Attachment 3. Samples shall be coUected during dayUght hours (sunrise to sunset). Dischargers need not coUect more than four (4) samples per montii. AU samples shall be taken in the receiving waters and shall be representative ofthe prevailing conditions ofthe water bodies. Samples shall be coUected from safely accessible locations upsfream of the constraction site discharge and immediately downsfream from the last point of discharge. For laboratory analysis, aU sampling, sample preservation, and analyses must be conducted according to test procedures under 40 CFR Part 136. Field samples shall be coUected and analyzed according to the specifications ofthe manufacturer ofthe sampling devices employed. Portable meters shall be calibrated according to manufacturer's specification. All field and/or laboratory analytical data shall be kept in tiie SWPPP document, which is to remain at tiie constiniction site at all times until a Notice of Termination has been submitted and approved. 8, Monitoring Program for Pollutants Not Visually Detectable in Storm Water A sampling and analysis program shall be developed and conducted for pollutants which are not visually detectable in storm water discharges, which are or should be known to occur on the constraction site, and which could cause or contribute to an exceedance of water quality objectives in the receiving water. Pollutants that should be considered for inclusion in this sampling and analysis program are those identified in Sections A.5.b. and A.5.C. Constraction materials and compounds that are not stored in water-tight containers under a water-tight roof or inside a building are examples of materials for which the discharger may have to implement sampling and analysis procedures. The goal ofthe sampling and analysis is to determine whether the BMPs employed and maintained on site are effective in preventing the potential pollutants from coming in contact with storm water and causing or contributing to an exceedance of water quality objectives in the receiving waters. Examples of construction sites that may require sampling and analysis include: sites tiiat are laiown to have contaminants spiUed or spread on the ground; sites where constraction practices include the application of soil amendments, such as gypsum, which can increase the pH of the runoff; or sites having uncovered stockpUes of material 22 exposed to storm water. Visual observations before, during, and after storm events may trigger the requfrement to coUect samples. Any breach, malfunction, leakage, or spiU observed which could result in the discharge of pollutants to surface waters that would not be visually detectable in storm water shall trigger fhe collection of a sample of discharge. Samples shall be collected at all discharge locations which drain the areas identified by the visual observations and which can be safely accessed. For sites where sampling and analysis is required, personnel frained in water quality sampling procedures shall collect storm water samples. A sufficientiy large sample of storm water that has not come in contact with the disturbed soil or the materials stored or used on-site (uncontaminated sample) shall be collected for comparison with the discharge sample. Samples shall be collected during the first two hours of discharge from rain events that occur during daylight hours and which generate runoff. The uncontaminated sample shall be compared to the samples of discharge using field analysis or through laboratory analysis. Analyses may include, but are not limited to, indicator parameters such as: pH, specific conductance, dissolved oxygen, conductivity, salinity, and TDS. For laboratory analysis, all sampling, sample preservation, and analyses must be conducted according to test procedures under 40 CFR Part 136. Field discharge samples shall be collected and analyzed according to the specifications of the manufacturer of the sampling devices employed. Portable meters shall be calibrated according to manufacturer's specification. All field and/or analytical data shall be kept in the SWPPP document, which is to remain at the constraction site at all times until a Notice of Termination has been submitted and approved. SECTION C: STANDARD PROVISIONS FOR CONSTRUCTION ACTIVITY 1, Dutv to Complv The discharger must comply with all of the conditions of this General Pennit, Any permit noncompliance constitutes a violation of the Clean Water Act (CWA) and the Porter-Cologne Water Quality Confrol Act and is grounds for enforcement action and/or removal from General Permit coverage. 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 fhis General Pennit has not yet bem modified to incorporate the requirement, 2, General Permit Actions This General Permit may be modified, revoked and reissued, or terminated for cause. The filing of a request by the discharger for a General Pennit modification, revocation 23 and reissuance, or tennination, br a notification of planned changes or anticipated noncompliance does not annul any General Permit condition. 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 fhe discharge and that standard or prohibition is more stringent than any limitation on the pollutant in this General Permit, this General Pennit shall be modified or revoked and reissued to conform to the toxic effluent standard or prohibition and the dischargers so notified. 3. Need to Halt or Reduce Activitv 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. 4. Dutv to Mitigate The discharger shall take all responsible steps to minimize or prevent any discharge in violation of fhis General Permit, which has a reasonable likelihood of adversely affecting human health or the envfronment. 5.

NHWB Page 1 of 5 New Home Buyer Water Brochure your home. your community, your environment. Simple things you can do in and around your new home to protect and preserve clean water. congratulations on the purchase of your new home! As you begin to work on making your new house your home, California's home builders want to remind you of the important role you can play in protecting and preserving our state's valuable water resources http ://www.cbia.org/nhwb.htinl 12/7/00 NHWB Page 2 of 5 and environment. How you perform the special and routine activities designed to maintain the beauty and comfort of your home - from painting a room to caring for your lavm and garden - can have a significant impact on the quality of California's water resources and the region's environment. When your home was built, extensive precautions were taken by home builders to prevent the local creeks, streams, and waterways from being polluted by water ninoff and debris at the construction site. The low plastic fences and hay bales you may have seen in the construction areas represent the types of environmental management measures used to limit erosion and storm water runoff. Now it is your turn . Here are several simple suggestions for you to follow to do your part in keeping water clean for your community and the environment. A did you know. The activities you carry out around your home could affect local streams, rivers, and lakes even though you may live miles away from those types of wildlife areas. W^ater from a garden hose or a storm can carry automotive and household materials, such as motor oil, fertilizers, household cleaners, and garbage, to local streams, rivers, and lakes through a storm drain. One quart of motor oil spilled dovm a storm drain can contaminate 250,000 gallons of water. Lawn clippings and other yard waste deposited in storm drains can affect water quality of creeks and streams. Over-appUcation of fertilizer can wash down into a storm drain and enter creeks and streams making algae grow, which deprives fish of oxygen. Over-watering lavms can cause soil erosion that could eventually obstruct flood control channels and create seepage problems for your neighbors. Plus, it's a waste of water. what you can do http://www.cbia.org/nhwb.html 12/7/00 NHWB Page 3 of 5 to help keep the water clean., ...and preserve the environment. Properly use and store all toxic products, including solvents, paints and cleaners. Use completely paint cleaners and other products or share leftovers with a neighbor. Take household hazardous materials containers, such as pesticides and used motor oil to a hazardous material 'collection center. Contact the County for the nearest location. Use kitty litter or other absorbent materials to clean spills, rather than hosing down spills. Depending on the substance, dispose used absorbent materials in the trash can or at a hazardous materials collection center. Rinse water-based paint brushes in the sink. Filter and reuse paint thinner or brush cleaners. Dispose of used thinner, oil and latex paint at a hazardous materials collection center. Use pesticides, herbicides and fertilizers in accordance with label instructions. Do not apply before rain and always dispose of leftovers at a hazardous materials collections center. Control erosion during landscaping projects to prevent dirt and debris from entering storm drains. Conserve water by using landscaping materials that are suited to your climate. ^Throw all rubbish in tightly sealed trash cans. ^Recycle reusable materials, but be sure materials won't blow out of the recycling bin before they are collected. Pick up and properly dispose of litter in your neighborhood. Use a broom rather than a hose to clean up garden clippings. Put leaves and clippings in a trash can or a compost pile. Divert rain spouts and garden hoses away from paved surfaces and onto grass to allow water to filter through the soil. Program your watering system to water less during the rainy season, and remember to turn the sprinklers off on expected rainy days. http ://www. cbia. org/nhwb .html 12/7/00 NHWB Page 4 of 5 './Li Conserve water when washing your car. Wash engines at a 'Do it Yourself Car Wash' where the drainage is not connected ho the storm drain. Pick up animal waste and dispose in the trash can. Californians measure their quality of life by the homes they live in, the communities they work and reside in, and the natm-al environment they rest and recreate in.

Several activities that you do at your home have the potential to pollute runoff Potential pollutants from homes include oil, grease and other petroleum hydrocarbons, heavy metals, litter and debris, animal wastes, solvents, paint and masonry wastes, detergents and other cleanmg solutions, and pesticides and fertilizers. How you manage your home impacts the ocean, even ifyou live several miles from the beach. Everything that exits your property will eventually nm into the ocean. The sources of residential pollutants include household toxics, litter and debris, and runoff from car washing, pool and spa care, lawn maintenance and on-site domestic sewage treatment systems.. It is very important to properly manage and dispose of household toxics to keep your family safe and to prevent pollutants to runoff Did you know that oil and grease from automotive maintenance; paint, masonry and cleaning wastes from home repairs and maintenance; pesticides and fertilizers from garden care are all considered household toxics? Oil and grease wastes from leaking car engines and maintenance and repair activities may contain a wide variety of toxic hydrocarbon compounds and metals at varying concentrations, and that exposure may be toxic to aquatic plants and organisms. Other wastes may be poured into storm drains or pollute runoff from maintenance activities conducted by homeowners, including paint and masonry wastes, solvents, detergents from car wash activities, residues from carpet cleaning and pool and spa care. Call the Household Toxics Hotline, (800) 246-1233, for free disposal options available in your area. Household Toxics Pesticides and Fertilizers Improper disposal of household toxics into stonnwater can endanger aquatic habitat. For example, using excessive amoimts of pesticides and fertilizers during landscape maintenance can contribute nutrients, such as nitrogen and phosphorus, and toxic organic substances, such as organophosphates and carbamates, into stormwater. Toxic materials can damage aquatic hfe and nutrients can result in excessive algae growth in waterways, leading to cloudiness and a reduced level of dissolved oxygen available to http ://www.co .san-diego .ca.us/deh/stonnwater/residential.html 12/5/00 Residential Page 2 of3 aquatic life. And unionized ammonia (nitrogen form) can kill fish. Litter and Debris It is also important to properly disposal of litter and debris, including cigarette butts and green waste (leaves and grass clippings from landscape maintenance activities). Decaying organic matter reduces the amount of dissolved oxygen available to aquatic life. Litter and debris can plug up storm drains and reduce the aesthetic quality ofthe receiving waters Human pathogens Human pathogens (bacteria, parasites and vimses) can also pollute run off! Common sources of human pathogens are improperly managed pet wastes and on-site domestic sewage treatment systems. High levels of coliform bacteria in stormwater, which are used as an indicator of fecal contamination and the potential presence of pathogens, may eventually contaminate waterways and lead to beach closures. Decomposition of pet wastes discharged to receiving waters also demand a high level of oxygen, which reduces the amoimt of dissolved oxygen available to aquatic hfe. You can help control runoff pollution by doing the following: • Do not dispose of liquids or other materials to the storm drain system • Report illegal dumping of any substance (Uquids, trash, household toxics) to the County's toll free, 24-hour hotline 1-888-846-0800 • Utilize the County Household Toxics Program at (800) 246-1233, for disposal of household toxics • Keep lawn clippings and other landscaping waste out of gutters and streets by placing it with trash for collection or by composting it • Clean up and properly dispose of pet waste. It is best to flush pet waste. Altematives to flushing are placing into trash or burying it in your yard (at least 3-fl deep). • Observe parking restriction for street sweeping. • Wash automobiles at car washes or on pervious surfaces (lawns) to keep wash water out of the storm drain system. • Avoid excessive or improper use or disposal of fertilizers, pesticides, herbicides, fungicides, cleaning solutions, and automotive and paint products. • Use biodegradable, non-toxic, and less toxic altemative products to the extent possible. • Cover garbage containers and keep them in good repair. • Sweep sidewalks instead of hosing down. • Water lawn properly to reduce runoff For more information, please call the County Stormwater hotline (619) 338-2048 or toll-free (888) 846-0800 Comments/Suggestions?

STORM WATER POLLUTION PREVENTION PLAN La Suvera CDP 04-16 BEST MANAGEMENT PRACTICES (CONSTRUCTION) BMP Objectives Based on the proposed construction, the construction schedule, the site specifics, the anticipated pollutants, the BMP objectives that all Craftsman Carlsbad I, LLC personnel and onsite contractors must adhere to are as follows: Practice Good Housekeeping Perform activities in a manner which keeps potential pollutants from leaving the site by managing pollutant sources and modifying construction activities. Contain Waste Stabilize Disturbed Areas Dispose of all construction waste in designated areas (to be shown on Wall Map by contractor and approved by field superintendent), and keep storm water from entering or leaving these areas. Keep containers of waste up off ground (i.e., on pallets) and cover to avoid runoff during storms. Provide temporary stabilization of disturbed soils whenever active construction is not occurring on that portion of the site. Provide permanent stabilization after fine grading operations and landscape the site. Control Site Perimeter Control Internal Erosion Runoff from the project site should be free from excessive sediment and other pollutants through the use of silt fencing, rock bags, hydro-mulch, fiber rolls, etc., placed at strategic locations throughout the site. Detain waters that contain sediment and other pollutants from the disturbed areas of the site throughout specific stages of project development. To achieve these objectives during construction, BMPs have been selected from two categories: • Contractor Activities and • Erosion and Sediment Control BMPs are indicated for specific pre-construction, construction and post-construction phases, and where appropriate, defined for PreparedBy: Dl Hunsaker & Associates San Diego, Inc. H:\SWPPP\2470/002\Main STORM WATER POLLUTION PREVENTION PLAN La Suvera CDP 04-16 specific areas within the project area. The primary targeted pollutants are sediment, oil and grease, and floatable materials. Contractor Activities Structure Construction/ Painting Material Delivery and Storage These BMPs are measures aimed at reducing the amount of sediment and other pollutants that become available for transport by storm water or non-storm water runoff by monitoring and managing construction activities as the project progresses. The construction of houses using normal construction materials involves many materials that are potential pollutants. Craftsman Carlsbad I, LLC personnel are responsible for ensuring that contractors control all construction activities on a regular basis to avoid pollutants from coming into contact with storm water and leaving the site. Specific activities assigned to Craftsman Carlsbad I, LLC supervisory staff and contractors include the following: • Conduct regularly scheduled walk-downs of active areas; report discrepancies to contractor for immediate corrective action. Sweep the area as needed. Do not sweep debris into storm drain svstems. Debris should be collected and deposited into areas of open soil as long as debris consists mainly of soil material. Report all contaminated soil material to Craftsman Carlsbad I, LLC supervisory personnel for immediate action. • Inform subcontractors of company policy on these matters and include appropriate provisions in their contracts to make certain proper housekeeping and disposal practices are implemented. Many materials used in construction are potential storm water pollutants. Craftsman Carlsbad I, LLC supervisory personnel will monitor all material deliveries as is practical to assure that contractors: • Fuel and lubricate equipment using mobile units to avoid storage of oil and grease onsite. • Keep any potential pollutants that have to be stored onsite in secondary containment as shown on the SWPPP Wall Map, kept on construction trailer wall. PreparedBy: DI Hunsaker & Associates San Diego, IIK. H:\SWPPP\2470/002\Main STORM WATER POLLUTION PREVENTION PLAN La Suvera CDP 04-16 Keep materials that are potential pollutants covered to avoid contact with rainwater. Label containers containing potentially hazardous or toxic materials (i.e., paints, oils, fuels, etc.). Solid Waste Management Solid waste is one of the major pollutants resulting from construction. Contractor must assure that dumpsters are in place for collection of solid waste. Label dumpsters "Solid Waste Only". Craftsman Carlsbad I, LLC personnel will monitor the collection areas as part of the regularly scheduled site inspections/ rounds. The locations of the dumpsters shall be shown on the SWPPP Wall Map. Collect site trash on a daily basis. Hazardous Waste Management Many of the materials used onsite can be hazardous materials, which can become hazardous waste if improperly disposed of. Herbicides and pesticides may only be applied by certified applicators. Use containment berms in fueling areas. Provide secondary containment in paint mixing and clean-up areas. Do not clean out brushes or rinse paint containers into the dirt, street, gutter, or storm drain. Collect and dispose of painting materials in approved manner offsite. Store hazardous materials in original containers only in a designated storage area. Return all unused materials to designated storage areas daily. The location of these materials shall be shown on the SWPPP Wall Map. Concrete Waste Management Concrete washout particulates can contaminate storm water if not properly managed. Dispose of concrete washout in an earthen basin to dry and then be disposed of properly to prevent particulates from entering storm water runoff. DO NOT WASH INTO CURBS AND GUTTERS. If constructing exposed aggregate finish, detain wash water so that fine particulates do not enter storm drain system. Prepared By: Dl Hunsaker & Associates San Diego, Inc. H:\SWPPP\2470/002\Main STORM WATER POLLUTION PREVENTION PLAN La Suvera CDP 04-16 Pavement Construction Management Proper management of pavement construction materials and activities minimizes or eliminates discharges to gutters, storm drains, and watercourses resulting from on-site road paving, surfacing, and asphalt removal activities. • Apply concrete, asphalt, and seal coat during dry weather to prevent contaminants from contacting storm water runoff. • Cover storm drain inlets and manholes when paving or applying seal coat, tack seal, slurry seal, fog seal, or similar materials. • Always park paving machines over drip pans or absorbent materials, since they tend to drip continuously. • Protect drainage ways by using earth dikes, straw bales, sand bags, or other controls, which will divert or trap and filter runoff. When making saw-cuts: • Use as little water as possible • Cover each catch basin completely with filter fabric and contain the slurry by placing barriers around the catch basin (straw bales, sand bags, gravel dams). • Shovel, absorb or vacuum the slurry residue from pavement or gutter and remove from site at the end of the day or job. • Immediately remove any saw-cut slurry entering storm drain. When washing down exposed aggregate concrete: • Wash only when wash water can either flow into a dirt area, drain onto a bermed surface from which it can be pumped and disposed of in sanitary sewer or by a hazardous waste disposal program, or be vacuumed from a catchment created by blocking a storm drain inlet. • If necessary, place straw bales down slope, or divert runoff with temporary berms. • Make sure runoff does not reach gutters or storm drains. • Allow aggregate rinse to settle, and pump the water to the sanitary sewer if allowed by local wastewater authority. Prepared By: Dl ^ H;\SWPPP\2470/002\Main Hunsaker & Associates San Diego, Inc. STORM WATER POLLUTION PREVENTION PLAN La Suvera CDP 04-16 Vehicle and Equipment Maintenance • Collect and return sweepings from exposed aggregate concrete to stockpile or dispose with trash; never wash into a street or storm drain. Recycle broken concrete and asphalt. Inspect and maintain machinery regularly to minimize leaks and drips. Inspect inlet protection measures before and after rainfall events. During extended storms, inspect at least every day. If subjected to non-storm water flows, inspect daily. Maintain inlet protection so that water is not allowed to back up onto areas subject to traffic. If such backup occurs, the protective device must be removed and alternative measures deployed. Check with employees and subcontractors to ensure that measures are being followed. Oil, grease and other hazardous substances can be picked up from vehicles and construction equipment by storm water. Therefore, all Craftsman Carlsbad I, LLC personnel and onsite contractors must assure that the following activities are managed on a daily basis: Maintenance • Inspect and maintain all construction equipment to prevent oil or other fluid leaks. Report all leaks and spills to your immediate supervisor. • Keep stockpiled spill cleanup materials readily accessible. Craftsman Carlsbad I, LLC General Superintendent or his designee will inspect spill cleanup materials on a bi- monthly basis. • Onsite contractors should check incoming vehicles and equipment for leaking oil and fluids. Do not allow leaking vehicles or equipment onsite. Fueling (Grading and Site improvement Activities) • Fueling may only occur onsite using mobile fueling units. Contractors must ensure that all fueling and fuel staging areas are located away from drainage. Prepared By: Dl Hunsaker & Associates San Diego, Inc. H:\SWPPP\2470/0O2\Main STORM WATER POLLUTION PREVENTION PLAN La Suvera CDP 04-16 • Locate on-site fuel storage tanks within a bermed area designed to hold the tank volume. • Cover retention area with an impervious material and install it in a manner to ensure that any spills will be contained in the retention area. • Contractors must always have spill control materials nearby to capture any spills from fueling that may result. Washing • Do not permit steam-cleaning onsite. • Use vehicle drip sheets in accordance with Figure 6.1 to avoid contaminating soil when equipment is maintained or stored onsite. Keep in covered area when not in use. Spill Prevention and Control Spill prevention and prompt appropriate spill response reduces the potential for polluting receiving waters and spilled contaminants. Spills of concern include chemicals and hazardous wastes such as soil stabilizers/binders, dust palliatives, herbicides, growth inhibitors, fertilizers, de-icing products, fuels, lubricants, paints, and solvents. Spill Tvpes Be prepared for spills. Locate and clearly label spill kits and used absorbent containers. Respond to all spills immediately upon discovery. The appropriate spill response is determined by the quantity and/or composition of spilled substance, as follows: • A "minor spill" involves a small quantity of oil, gas, paint, etc. that can be controlled by the first responder upon discovery of the spill. • A "semi-significant spill" can be controlled by the first responder with the aid of other personnel and may require cessation of all other activity. • A "significant/hazardous spill" is a spill that cannot be controlled by personnel in the immediate vicinity. Minor Spill Response • Contain the spill • Recover the spilled material • Clean the spill area. Use absorbent materials. Do not hose down the area. • Dispose of clean-up materials appropriately ''"l^^-™ ° H:\SWPPP\2470/002\Main Hunsalcer & Associates San Diego, Inc. STORM WATER POLLUTION PREVENTION PLAN La Suvera CDP 04-16 Semi-Significant Spill Response • On impermeable surfaces, surround the spill with absorbent material to contain it. Clean spill using absorbent material. • On dirt areas, construct an earthen dike to contain the spill. Dig up contaminated soil and dispose of properly. • If spill occurs during rain, cover spill area to prevent contaminating storm runoff. Significant/Hazardous Spill Response • Contractor notifies the RE immediately. • Contractor calls 911 and appropriate county officials. • Contractor notifies the Governor's Office of Emergency Services Warning Center (805) 852-7550. • For spills meeting federal quantities, the contractor notifies the national Response Center (800) 424-8802. • All verbal notification must be followed up by written reports. • Contractor obtains services of spill contractor or a HazMat team immediately. Contractor staff is not to attempt cleanup until qualified assistance has arrived onsite. Education Train employees regarding the appropriate response for spills for the materials they use. Incorporate spill response procedures into regular safety meetings. Preventative Measures and Troubleshooting Guide Field Condition: Common solutions are: Material spills occur on a permeable surface. Contain spread of spill with an earthen dike. Dig up and properly dispose of contaminated soil. Material spills occur on an impermeable surface. Use dry absorbent materials to encircle and contain the spill. Place clean-up materials in a drum and dispose of properly. The spill exceeds the capacity of spill clean-up Contain spill. Obtain enough spill clean-up materials to completely clean up the spill. Contact Caltrans Maintenance. Store additional spill clean-up materials as necessary Spilled material encroaches on travel way. Contact Caltrans Maintenance. Use additional spill clean-up materials as necessary and replenish these materials in adequate quantity for future use. PreparedBy: Dl Hunsaker & Associates San Diego, Inc. H:\SWPPP\2470/002\Main STORM WATER POLLUTION PREVENTION PLAN La Suvera CDP 04-16 Erosion Control The most efficient way to address erosion control is to preserve existing vegetation where feasible during construction periods and to re-vegetate disturbed areas as soon as possible after grading or construction. In addition to other practices. Craftsman Carlsbad I, LLC will utilize a series of temporary erosion control techniques to minimize exposures during rough grading, site improvement and construction phases, including use of: temporary seeding, permanent seeding, mulching, soil blankets, or sod application. In conformance with the above, the SWPPP Wall Map includes the following (if applicable): • A perimeter outline of the areas of vegetative soil cover or native vegetation that will remain undisturbed during the construction project. • A perimeter outline of the areas of soil disturbance including cut or fill areas that will be covered during the rainy season by temporary seeding, mulch, or blankets, etc. and notes representing areas of potential soil erosion where sediment control BMPs are required to be used during construction. • A description of the BMPs used with particular attention paid to unprotected mass graded areas and stockpiled materials. Sediment Control The SWPPP Wall Map (located on construction trailer wall) includes a description or illustration of BMPs that will be implemented to prevent a net increase of sediment load in storm water discharge relative to natural levels. Sediment control BMPs are required at appropriate locations along the site perimeter and at all operational internal inlets to the City of Carlsbad storm drain system at all times during the rainy season. These are the most basic measures to prevent sediment from leaving the project site. There may be occasions when work on active areas precludes the use of sediment control BMPs temporarily. Under these conditions. Craftsman Carlsbad I, LLC and onsite contractors are to establish perimeter controls prior to the onset of rain, per the General Permit requirements. PreparedBy: Dl Hunsaker & Associates San Diego, Inc. H:\SWPPP\247O/002\Main STORM WATER POLLUTION PREVENTION PLAN La Suvera CDP 04-16 Debris Fence Seeding and Planting Dust Control In developing and implementing control practices, Hunsaker & Associates, Inc. has determined the peak flow-rates based on a 6- hour rainfall duration for a 100-year return interval, as shown in Appendix T. All criteria requested for compliance with the RWQCB will be implemented with construction. Craftsman Carlsbad I, LLC will consider and use, as necessary, a full range of sediment controls such as fiber rolls, silt fences, storm drain inlet protection, sediment traps, temporary sediment basins, gravel bag dikes and/or other controls. Craftsman Carlsbad I, LLC will consider additional site-specific and seasonal conditions at various phases of project development when selecting and designing the BMPs. An Erosion Control Plan for the La Suvera project. Drawing 403-5A (see Appendix T) has been approved by the City of Carlsbad including appropriate erosion control measures from the following: During construction, temporary debris fences will be constructed at points of run-on from large natural areas. These will capture debris, including sediment, before runoff enters the underground storm drain system. Visual inspections should be made following each runoff-producing storm event, to ensure that the fence is functioning properly and is not clogged with debris. Debris fences will be maintained by the Contractor during construction. To minimize exposure of newly graded slopes to the elements: • Hydro mulch slope areas as soon as they are constructed. • Install permanent ground cover on slopes concurrent with final grading and the construction of homes. • Maintain hydro mulch and landscaping for continued coverage throughout the final phases of project development. All landscaping contractors must ensure that workers install downstream gravel bags or silt barriers during active planting and watering, and clean up all areas daily to avoid sedimentation onto public rights of way. The silty sands onsite may be subject to erosion by prevailing winds as well as tracking and grinding of soils materials by construction vehicles. Therefore, Craftsman Carlsbad I, LLC has implemented street weeping around the site twice weekly, and will apply water to heavily tracked and graded areas during the dry season on an as needed basis. PreparedBy: DI Hunsaker & Associates San Diego, Inc. H:\SWPPP\2470/002\Main STORM WATER POLLUTION PREVENTION PLAN La Suvera CDP 04-16 Stabilized Construction Entrance Construction vehicle and equipment traffic from the site is a significant source of transportation for sediment. From the wheels of the vehicles, it is deposited on the city streets, and from there, into the storm drain system. Craftsman Carlsbad I, LLC will construct and maintain a stabilized construction entrance in accordance with Figure F2, or a satisfactory alternative such as the TRACKCLEAN product at the location shown on the Erosion Control Plan as necessary per construction use and weather conditions. Site personnel will monitor the condition of the entrance at least weekly or more often as required. Area supervisors will be advised to report problems to Craftsman Carlsbad I, LLC supervisors immediately. Street Sweeping and Vacuuming Street sweeping and vacuuming are practices to remove tracked sediment from public roads in order to prevent sediment and dirt from entering storm drains or receiving waters. Areas of concern include, but are not limited to, ingress and egress points. Sweepers should have vacuum or other mechanical attachments for collecting dirt and sediment. Inspect project ingress and egress points and roadways daily for signs of tracked sediment. After sweeping is finished, properly dispose of sweeper waste. For collected sediment that is free of trash and debris, consider incorporating the sediment back into the project's earthwork operations. If sweeping causes excess dust, use sweeper with water spray device to reduce dust. Silt Fence/Fiber Roll Barrier Craftsman Carlsbad I, LLC will develop and implement BMPs in a manner that creates "lines of defense" within the project site and at the site perimeter. The goal is to keep waters moving to allow silt to drop out and be collected for deposition at the site's primary disposal area. A silt fence consists of filter fabric, usually reinforced with wire, which is entrenched and attached to poles for support. Fiber rolls, also known as sediment logs or wattles, are composed of biodegradable fibers stuffed in photodegradable, open-weave netting and designed to reduce sediment runoff from disturbed soils into the storm drain system or watercourses. Fiber rolls are porous and allow water to filter through fibers and trap sediment, increase filtration rates, slow runoff, and reduce sheet and rill erosion. PreparedBy: DI Hunsaker & Associates San Diego, Inc. 10 H:\SWPPP\2470/002*lain STORM WATER POLLUTION PREVENTION PLAN La Suvera CDP 04-16 Wattles also create a favorable environment for plant establishment. Fiber rolls are applied as follows: Along sloped areas adjacent to sidewalks and roadways Along the face of exposed and erodible slopes to shorten slope length At entryway during active construction phases End-to-end in a shallow trench and staked in place At grade breaks where slopes transition to a steeper slope In drainage swales to slow flows Along stream banks to assist stabilization and re- vegetation On site personnel will construct silt fences or fiber roll barriers in locations shown on the Erosion Control Plan / Wall Map, in accordance with Figures F3 and F10. Craftsman Carlsbad I, LLC and contractor personnel will check installed barrier DAILY during the rainy season and twice weekly during dry season. Personnel will maintain barriers by removing all accumulated material after any significant rainfall, or when accumulated material exceeds six inches. All accumulated materials will be removed to the disposal area and checked prior to disposal for debris. Repair or replace silt fence/fiber rolls as required. Gravel Bag Barrier Stacked gravel bags create a barrier to detain sediment-laden runoff, promoting sedimentation. Craftsman Carlsbad I, LLC and contractor's personnel will install gravel bag barriers in locations shown on the Erosion Control Plan and/or noted on the SWPPP Wall Map, in accordance with Figures F7 through F9. Craftsman Carlsbad I, LLC and contractor's personnel will check installed barriers DAILY during the rainy season and twice weekly during dry season. Personnel will maintain barriers by removing all accumulated material after any significant rainfall, or when accumulated material exceeds six inches. All accumulated Prepared B): DI Hunsaker & Associates San Diego, Inc. 11 H:\SWPPP\2470/002\Main STORM WATER POLLUTION PREVENTION PLAN La Suvera CDP 04-16 materials will be removed to the disposal area and checked prior to disposal for debris. Repair or replace gravel bags as required. Storm Drain Inlet Protection Sediment Basin Inlet protection devices are designed to prevent sediment-laden storm water from entering a storm drain until some of the sediment has a chance to settle out. There are a variety of devices, depending upon the state of the project (i.e., if the streets are paved, ifthe storm drain is connected, etc). On a site-specific basis in conjunction with planned project construction meetings, on site personnel will construct storm drain inlet protection in locations shown on the Erosion Control Plan or as revised on the SWPPP Wall Map, in accordance with Figures 6.6 to 6.10. Emphasis will be placed on constructing inlet protection during current construction phases, when construction vehicles are most active. On site personnel will maintain protection devices by removing all accumulated material after any significant rainfall, or when accumu- lated material exceeds six inches. All accumulated materials will be removed to the disposal area and checked prior to disposal for debris. Repair or replace devices as required. Sediment control BMPs are required at appropriate locations along the site perimeter and at all operational internal inlets, as shown on the Erosion Control Plan, to prevent a net increase of sediment load in the storm water discharge relative to pre-construction levels. Sediment control practices may include filtration devices and barriers (such as fiber rolls, silt fences, and gravel inlet filters) and/or settling devices (such as sediment traps or basins). Effective filtration devices, barriers and settling devices shall be selected, installed and maintained properly. A proposed schedule for deployment of sediment control BMPs is included in Appendix H. Limited exceptions may be authorized by the RWQCB when work on active areas precludes the use of sediment control BMPs temporarily. Under these conditions, the discharger must have a plan to establish perimeter controls prior to the onset of rain. If the discharger chooses to rely on sediment basins for treatment purposes, sediment basins shall, at a minimum, be designed and maintained according to one of the four options listed in Section A.8 ofthe General Permit (see Appendix N). Prepared By: DI Hunsaker & Associates San Diego, Inc. 12 H:\SWPPP\2470/002\Main STORM WATER POLLUTION PREVENTION PLAN La Suvera CDP 04-16 A sediment basin shall have a means for de-watering within 7 calendar days following a storm event. Sediment basins may be fenced if safety (worker or public) is a concern. The outflow from a sediment basin that discharges into a natural drainage channel shall be provided with outlet protection to prevent erosion and scour of the embankment and channel. Sediment basins will require regular maintenance by onsite staff to remove accumulated silt deposits. Repair or replace basin and outlet riser as required. If a future condition requires the project to be halted, the sediment basins will be reconstructed and be maintained until such time that construction recommences. 13 Prepared By: Dl I *J H:\SWPPP\2470A)02\Main Hunsaker & Associates San Diego, inc. storm Water Pollution Prevention Plan FLYHOOO GORNE-R BRACE HE Avr purr PLASTIC, STAPLED TO 2X4'5 MODIFICATIONS TO THIS DETAIL TO BE NOTED ON THIS SHEET AND/OR THE SWPPP BASEMAP AND OVERLAY.

Scrap lumber and fastener debris Draft BMPs: CAI- Material Storage Onsite staging and storage of treated lumber and other polluting materials (including caulks and sealants) must be palletized or otherwise raised above the ground, covered overnight, and covered prior to impending rain. Use designated material and equipment storage yards for overnight storage of these materials, wherever possible. Truck deliveries of treated lumber that need to be staged (i.e. cannot be delivered to designated storage yards) must be placed at designated material drop locations or away from drainages, sensitive~areas, and the dripline of retained trees whenever possible or as agreed to in the contract scope of work. Minimize the number of material drop locations. (See Caltrans BMPs No. WM-1 or equivalent.) CA2- Materials Use and Waste Management Minimize amount and application area of glues, sealants, and caulks in work areas that are exposed to rainfall. Drips in exposed locations that wiil not cure/dry prior to impending rain must be cleaned up. Spills of hazardous materials must be cleaned up immediately. Waste from hazardous materials use, including treated lumber, must be disposed as hazardous waste, hauled offsite, or disposed of as agreed to in the contract scope of work. Scrap lumber, fasteners, and other inert waste that cannot be reused may be disposed of onsite as solid waste or hauled away. Waste from most adhesive and caulk tubes, if completely empty, may also be disposed of onsite in solid waste containers. (Caltrans BMP No. WM-2.) CAS- Sawdust/Sanding Management Temporaty chop yards with mounted power saws (including saws, stair cutters, and roof cutters) must be located away from drainages and must be equipped with a sawdust collection box or bag that is maintained properiy. A sediment control BMP, such as straw wattle or an equivalent, should be placed on the downgradient perimeter. Individuals using handheld power saws and sanders should work in areas that are not exposed to rainfall whenever possible. Handheld sanding equipment that is equipped with dust collection bags (orthe equivalent) must use bags when working in rain- exposed locations. Visible accumulations of handsawing and sanding debris outside the chop yard in areas that are exposed to rainfall must be removed or covered prior to the end of the workday and immediately in case of impending rain or as agreed to in the scope of work. Chop yards that are no longer active must be cleaned of lumber and carpentty waste and loose sawdust/sanding debris prior to the end of the workday or covered overnight until it can be removed or agreed to in the contract scope of work.

Cement-based waste and wastewater from equipment rinsing and cooling Draft BMPs: COI - Material Storage Onsite storage of cement or other caustic materials, including used form boards and molds, must be palletized or otherwise raised above the ground and covered ovemight and prior to impending rain. Use designated material and equipment storage yards for overnight storage of these materials, wherever possible. Truck deliveries of rebar, steel plates, and cable that need to be staged (i.e., cannot be delivered to designated storage yards) must be placed at material drop locations away from drainages and sensitive areas. Material in drop locations must be palletized orotherwise raised off the ground and be able to be covered prior to impending rain. Schedule material deliveries in a manner that reduces the time for onsite storage of potentially polluting materials prior to use and minimize the number of material drop locations. Temporary operational staging of concrete materials and equipment in exposed locations must be conducted over drop cloths, cardboard, or equivalent and be limited in quantity to the needs ofthe 'work at • hand.' Operational staging must be located away from drainages or waterways and from the dripline of retained trees, whenever possible. Forms and molds taken off wet concrete must also be staged over plastic sheeting or an equivalent until rinsed and dried. Remove or cover operational staging locations with a tarp, plastic sheeting, or equivalent immediately prior to impending rain and at the end of each workday or as agreed to in the contract scope of work. (See Caltrans BMPs Nos. WM-1 and WM-8 or equivalent.) C02- Stockpile Protection Temporary stockpiles of trench spoil, sand, and aggregate base course should be located on either unpaved areas or on heavy mil plastic, drop cloths or tarps over pavement. These temporary stockpiles must be rockbagged at the downgradient base perimeter and be able to covered with plastic weighted down (against winds) or an equivalent BMP prior to a rain event. Temporaty stockpiles of cement must also be bagged, palletized (or othenvise raised above the ground surface), sandbagged around the whole base perimeter, and be able to covered with plastic weighted down (against winds) or an equivalent BMP prior to a rain event. When individual stockpile use is complete, remove remaining material and clean visible residue by the end ofthe day or cover stockpile until it can be removed or as agreed to in the contract scope of work. (Caltrans BMPs Nos. WE-1 and SC-6.) C03- Timing for Wet Weather Do not place concrete during rain (precipitation that is sufficient to cause locai runoff) or within 18 hours of rain forecasted with a 40% or greater chance using an effective combination of: . websites including httD://nimbo.wrh.noaa.aov/Sandieao/index3.shtml (National Weather Service (NWS)- San Diego site) and wvw.weather.com for San Diego, CA (as shown in the "Hour by Hour Details" in the row entitled "Chance of Precipitation"); . local broadcast television weather; . U.S. Weather Bureau's telephone recording at 619.289.1212 (updated twice daily at 3am and 3pm); and .. NOAA's San Diego area radio weather news at 162.40 MHz (requires special radio receiver). C04- Storm Drain Inlet Protection Prevent cement and sediment from going down a storm drain. Construct storm drain inlet BMP(s) or ensure that adequate stonn drain inlet BMPs are in place within the drainage area affected by the day's work. Use Caltrans BMPs Nos. SC-10 and WM-4 or an equivalent. Residue and aggregate must be removed from the street and disposed of properiy (see C06 following) at the end of the day or as agreed to in the contract scope of work. COS- Material Mixing ~ Portable and manual mixing of concrete must be performed over a drop cloth, cardboard, plastic sheeting or equivalent with a berm on the downgradient perimeter, created by straw wattle, rockbags, or an equivalent. When adding water to the mixer, minimize wetting of the mixing operation area. Pour dty materials into the mixer in a manner that minimizes dust generation. Collect and secure empty bags of cement, colorant, and other chemicals and temporarily store over drop cloth, cardboard, plastic sheeting or an equivalent prior to disposal and be able to cover empty bags prior to impending rain.

C07- Concrete Management Drips on rain-exposed surfaces, such as streets, from concrete trucks and pumping equipment must be prevented by installing a bucket, drop clothes, or an equivalent under the area. In addition, place stoppers on concrete truck chutes during travel onsite to manage potential dribbling of concrete material. Handling of wet concrete, from swinging pumper chutes to transporting via wheelbarrow, must be performed in a controlled manner to prevent spills and drips onto nontarget surface. Waste concrete and rinsewater from concrete trucks, pumpers, wheelbarrow, buckets, portable mixers, and associated tools and protective clothing must be disposed of in a designated concrete washout facility or equivalent alternative washout facility (which includes portable containment and disposal systems). If concrete pumps are used onsite, a washout facility must be available that conforms with the <12" lip height needed for gravity flow from pumper chutes. If curb and gutter molds, crane buckets or similar implements are used onsite, the molds and implements must be stored on top of heavy mil plastic (or equivalent) until rinsed and dried. Minimize water use. Concrete drips, spills, overpours, and equipment rinsewater landing on rain-exposed outside of any BMP device must be immediately collected and have the surface cleaned and waste disposed of properiy by the end ofthe workday. [Note: An exception to requiring washout use may be available for those involved in supplying concrete to non-structural, below- ground-surface projects such as utility trenches. If authorized in the contract scope of work or approved by Site Project Manager, the involved concrete delivety trucks, buckets, and mixers may rinse chutes, associated equipment, and tools into the same open trench where the concrete was placed.] (Caltrans BMPs Nos. WS-8 and NS-8.) COS- Sawcutting, Coring, and Potholing Management Prior to starting, ensure there is an adequate BMP (or construct one) on storm drain catchbasin inlets within the drainage area affected by the day's work. Sawcutting, coring and potholing in concrete pavement, foundations, or other cement-based material must be conducted with immediate vacuum pickup of cooling water. Remaining dried residue of concrete, aggregate, or sediment must be swept up prior to the end of the workday, or immediately in case of impending rain, and disposed of as solid waste.

Roadway tracking . Maintaining and fueling heavy equipment onsite Draft BMPs: GR1- Soil Stabilization Clearing and grubbing and rough and finish grading work (both permitted or exempt from permitting) must have adequate erosion and sediment control BMPs installed for both slopes and flat (< 5% slope) areas. Conduct pre-construction coordination meeting(s) with Project Biologist(s) and Erosion and Sediment Control Professional(s) wherever possible. Erosion Control BMPs must be chosen from Caltrans Construction Site BMPs Nos. SS-2 through SS-8 for slopes and flat areas or an equivalent. Use of erosion control BMPs must be accompanied by sediment control BMPs. Sediment Control BMPs must be chosen from BMPs Nos. SC-1, SC-5, SC-6, SC-8, SC-10 or SC-2 to manage all disturbed areas. Responsibility for BMP installations should be agreed to in the contract scope of work. Minimize scale of incidentally graded areas on site, such as parking lots and staging areas (i.e., for material delivery, trash and waste disposal areas, and equipment storage), and install adequate sediment control BMPs or as agreed to in the contract scope of work. For grading of small sized and linear (typically trenching) projects, scrape off duff and stockpile it separately whenever possible for later re- vegetation use. GR2- Waterway and Environmentally Sensitive Area Preservation Review all SWPPP, Section 401 Water Quality Certiflcation, and Streambed Alteration agreements prior to starting work to ensure identiflcation and understanding of all project limits and sensitive areas. Respect designated riparian or environmentally sensitive areas by not encroaching on demarcated fencelines. (These fences are typically made of orange snow fencing or black silt fencing and encircle or separate the ESA from the work area.) Locate soil and waste stockpiles away from drainages and sensitive areas and ensure that erosion and sediment control BMPs are either in place or readily available for installation prior to a rain event. Avoid disturbing waterways where possible and comply with all permit conditions and site limits. Minimize the number stream crossings performed and limit crossings to designated location(s). (Please see Caltrans BMP Nos. SS-2 and NS-4 or equivalent.) 19 GR3- Dust Control Do not create visible dust clouds on work areas or access roads. On unpaved roads, do not exceed 15 mph.

Insulation and packaging scrap . Portable equipment fueling and maintenance Draft BMPs: INI-Material Storage Onsite staging or storage of insulation, caulks, foams, or other toxic materials must be palletized or othenvise raised above the ground, covered overnight, and covered prior to impending rain. Use designated material and equipment storage yards for overnight storage of these and other materials wherever possible. Truck deliveries of insulation that needs to be staged (i.e., cannot be delivered to designated storage yards) must be placed at designated material drop locations away from drainages and sensitive areas or as agreed to in the scope of work. Insulation in drop locations must be bagged and palletized or othenvise raised off the ground and be able to be covered prior to impending rain. Schedule material deliveries in a manner that reduces the time for onsite storage of potentially polluting materials prior to use and minimize the number of material drop locations. (See Caltrans BMPs Nos. WM-1 and WM-8 or equivalent.) 1N2- Material Use and Waste Management Use drop cloths or other protective materials when using glues, caulks, sealing foam, etc. until dried in work areas that are exposed to rainfall. Nailguns and staplers must be used in a controlled manner to minimize nail and staple waste falling onto rain-exposed surfaces. Scrap insulation that cannot be reused may be disposed of as solid waste or hauled offsite. Waste from adhesive and caulk tubes, if completely empty, may also be disposed of onsite in solid waste containers. (Caltrans BMP No. WM-2.) IN3- Litter Control Do not leave pieces of insulation, packaging, or other scrap materials in rain-exposed areas. Remove waste material prior to leaving for the day or as agreed to in the scope of work and in case of impending rain or high winds and dispose of properly. Reuse or recycle whenever possible.

Storage of potentially hazardous materials like fertilizers and pesticides . Chemical application to the ground . Vegetative material from trimmings, mowing, and blowing . Over-irrigation and erosion from water pressure . Inadequate ground cover on slopes . Equipment and tool maintenance Draft BMPs: LA1- Material Storage Onsite overnight storage of fuels, fertilizers, pesticides, herbicides, soil amendments (ie., lime, sulfur, iron, gypsum) or other toxic ingredients or materials must be properiy contained and stored under roof or in enclosed storage bins/rolloffs or an equivalent whenever possible. Truck deliveries of these and other materials, such as decorative rock and pavers that cannot be staged in the above referenced covered/enclosed facilities, must be placed at material drop locations away from drainages and sensitive areas or as agreed to in the contract scope of work. Schedule material deliveries in a manner that reduces the time for onsite storage of potentially polluting materials prior to use and minimize the number of rain-exposed material drop locations. Plants, trees, and shrubs staged in rain-exposed locations must be rockbagged (or an equivalent) at the downgradient perimeter. Loose soil, decorative cover, and sand staged in rain-exposed drop locations must be rockbagged around the perimeter and be able to be covered ovemight and immediately prior to impending rain. Temporary operational staging areas for chemical mixing, filling, and spraying operations in rain-exposed locations must be placed over drop clothes, cardboard, or plastic sheeting, limited in amount to the needs of 'work at hand," and must be at located away from drainages and from the dripline of any retained trees whenever possible. (See Caltrans BMP Nos. WM-1 and WM-6.) LA2- Application Control Application of herbicides and pesticides must be performed by a State/County licensed applicator. Select and use the least toxic, effective herbicide, pesticide, and fertilizer and minimize the amount used. For liquid spray application, do not overspray onto a nontarget surface and follow manufacturers precautions about windy conditions. For granular application (both hand or mechanical spreading), minimize overapplication onto nontarget surfaces and sweep up misplaced granules from hard surfaces. Do not use herbicides, pesticides, fertilizers, or soil amendments during a rainfall event or prior to impending rainfall if there is a potential for contaminating runoff. [Note: Any application of aquatic herbicides or pesticides must be performed in full compliance with the State Water Resources Control Board General Permit No. CAG990003.] (See Caltrans BMP No. WM-2.) 23 LAS- Vegetative Matter Control Preserve existing slope stabilization and sediment control BMPs whenever possible during landscape maintenance activities. Collect and properiy dispose of trimmed or pruned vegetative waste prior to the end of the work day. If using chipper/shredder equipment, remove debris accumulated near the unit prior to the end of the workday. If adding wood mulch on landscaped beds, remove mulch particles that remain on paved areas prior to the end of the workday or immediately in case of impending rain. Ensure that beds landscaped with loose mulch has a border installed or an equivalent means that will prevent material from flowing out of the bed onto paved surfaces during periods of inundation. Use mechanical or manual techniques, such as sweeping instead of hosing down surfaces with water. Leaf blowers must be controlled so that blown matter is directed away from curb, gutters and storm drain inlets. Instead when fine sediment needs removal, sweep or an equivalent method, to avoid generating visible dust clouds. Mower trimmings, soil, or vegetative matter dropped, swept or blown onto rain-exposed paved surfaces must be removed prior to the end of the workday or immediately in case of impending rain. Disposal of vegetative matter, sediment, and rinsate are prohibited from entering the storm drain system. (See Caltrans BMP No. SS-8.) LA4- Stockpile Protection Temporary material stockpiles of soils, sand, and soil amendments should be located on unpaved areas or over heavy mil plastic, drop cloths or tarps over pavement. Soil and sand stockpiles remaining at the end of the workday must be rockbagged at the base perimeter (or equivalent) and be able to be covered with plastic (or an equivalent) prior to a rain event. Soil amendment stockpiles (ie, lime, sulphur, iron, gypsum) located in rain-exposed areas must be covered overnight and immediately in case of impending rainfall. When temporary stockpile use is complete, remove remaining material and sweep or shovel visible residue from any paved areas by the end of the workday or cover stockpile until it can be removed or as agreed to in the contract scope of work. (Caltrans BMP Nos. WE-1 and SC-6 for more detail.) LAS- Storm Drain Inlet Protection Sediment must be prevented from going down a storm drain inlet. Construct stomn drain inlet BMP(s) or ensure that adequate storm drain inlet BMPs are in place within the drainage area(s) affected by the day's work. Use Caltrans BMPs Nos. SC-10 and WM-4 or an equivalent. Visible soil or particulate residue from planting, mulching, fertilizing, and maintenance activities on paved surfaces must be swept or shoveled and reused or disposed of properiy prior to the end of the day or as agreed to in the contract scope of work. LA6 Material Use and Waste Management For Landscapers: Use plastic sheeting or equivalent protective materials on the ground underneath fertilizer, herbicide, and pesticide mixing and filling operations. Spills must be cleaned up immediately. Waste soil from planting activity that cannot be reused may be disposed of at designated spoil collection location that is away from watenvays and environmentally sensitive areas, deposited in a solid waste container, or taken offsite. For Irrigators: During installation of irrigation systems, preserve existing site erosion and sediment control BMPs wherever possible. (See also LA4 Stockpile Protection BMP for other installation issues.) Use drop cloths, cardboard, or other surface protective materials on the ground when using glues, pipe dope, and flux until dried in work areas that are exposed to rainfall. (This is not necessaty for incidental drips of these materials into own working trench if the trench is refilled prior to the end of the workday.) Spills 24 must be cleaned up immediately. Waste product and used protective materials from such hazardous materials use, including used tubes and containers, must be disposed of in an approved hazardous waste disposal container or taken offsite. Scrap from irrigation system installation and non-hazardous waste must be removed and disposed of in solid waste containers. Trench spoil may be disposed of at designated spoil collection location that is away from watenvays and environmentally sensitive areas, in the solid waste container, or taken offsite. (Caltrans BMP No. WM-2.) LA7- Soil Stabilization Review site erosion and sediment control plan specifications and soil characteristics for relevent work areas. Preserve existing erosion and sediment control BMPs whenever possible during landscape planting and irrigation installation activities. If slope stabilizing BMPs are not in place on slopes [slopes are areas > 4:1 (H:V)] prior to landscape or irrigation installation, consult with Site Project Manager to ensure proper coordination with any other erosion control installers. Use mulch or an equivalent erosion control method together with planned trees, shrubs, and ground covers that do not provide adequate soil stabilization by themselves. Sediment control BMPs must also be used whenever erosion control BMPs are used. During planting activity, install straw wattles or an equivalent at the downgradient perimeter of the disturbed areas. (For more information on soil stabilization techniques see Caltrans BMPs No. SS-3 through SS-7.) LAS- Irrigation Management Only flush and pressure test irrigation lines after notifying Site Project Manager to ensure adequate erosion and sediment control BMPs are in place to prevent erosion at sprinkler head locations and sediment from entering stomn drain inlets or other conveyances within the drainage area affected by the testing. Manual watering of potted plant materials should be performed in a manner that minimizes runoff of the water. Design automatic sprinkler systems that operate on an as-needed basis (accounting for weather conditions) to prevent or minimize runoff, overspray or seepage. Include water conservation devices, such as low head drainage check valves and flow sensors or an equivalent for water pollution prevention purposes whenever possible. Follow regulatory guidelines for using reclaimed water. (See Caltrans BMP No. NS-7.) LA-9 Handhelds and Equipment Fueling and Maintenance Only necessaty oiling and lubing that is required for the proper functioning of handheld equipment, such as mowers, spreaders, and rototillers, is allowed onsite. Limit the frequency of fueling and maintenance of any associated portable generators and compressors to that necessaty for proper functioning. Portable fuel and oil containers must be stored in a tub or equivalent device to avoid spills and leaks. Drop cloths, trays or an equivalent method must be used underneath handheld and associated portable equipment to avoid leaking fluids, fuels, oils, or grease onto the ground. Do not overspray aerosols to the ground or other rain-exposed surfaces. Do not rinse equipment, such as mowers, onsite except if provided a designated washdown area in a maintenance yard. Clean up spills immediately and dispose of waste properiy. (Caltrans BMP Nos. NS 9 and NS-10.) LA-10 Heavy Equipment Fueling and Maintenance Only maintain tractors, bobcats, shedders, backhoes and other heavy equipment in designated locations away from watenvays, drainages, and sensitive areas or as agreed 25 to in the contract scope of work. Minimize the frequency of ser/icing activity. Servicing technicians must use proper spill prevention procedures during fueling and maintenance activities. Wrap absorbent pads around nozzle when fueling. Use automatic shut-off nozzles and do not "top-off' fuel tanks. Use drip pans or equivalent absorption devices under maintenance activity. Keep fliling nozzles upright when transferring between servicing vehicle and heavy equipment and do not place filling nozzle on the ground. Nozzles, hoses, and equipment must be in good working order. Use adequate lighting at night to see and access flil openings. A Spill Response Kit must be available on the maintenance and fueling vehicles. The Spill Response Kit must include at least 10 feet of containment boom and oleophilic absorbents or equivalent capable of absorbing a minimum of 25 gallons of petroleum. Servicing fimns must report spills to Site Project Manager. (See Caltrans BMPs Nos. NS-9 and NS-10 or equivalent.) LA-11 Equipment/Tool Rinsing and Wastewater Disposal Only necessary rinsing that is required for the proper functioning of equipment is allowed onsite. Onsite rinsing of mowers, sprayers, nozzles, hoses, and other equipment that have been in contact with hazardous materials, such as fuels, oils, and pesticides, must be performed in a bucket or utility sink/bath or an equivalent device that collects and contains wastewater. Use designated areas, such as Maintenance Yards, that are located away from drainages and outside the dripline of retained trees for rinsing equipment that has been in contact with hazardous materials wherever possible. Minimize water use. Non-aqueous-based wastewaters must be contained and removed by a contracted, qualified hazardous waste hauler for offsite disposal as hazardous waste. Aqueous-based wastewater must be disposed of by staging it in containers in a storage bin for pickup by a contracted, qualified waste hauler for offsite disposal or taking it offsite. Incidental rinsing of handtools and equipment coated with sediment may be performed onsite away from drainages. (Caltrans BMP Nos. NS-8 and WM-4.)

PS6- Material Use and Waste Management Lath Phase: When cutting and installing backing wire, sheathing, metal lath, plastic sheeting, and red tape, direct unused materials into bins, under roof, or an equivalent to minimize littering in rain-exposed areas. Do not overapply caulk. Remove scrap backing wire, sheathing, and wire mesh from the ground surface priorto plastering and consider reusing and recycling scrap before disposing. Remove scrap from rain- exposed areas prior to the end of the workday and dispose of, or stage for disposal, as solid waste. Plastering Material Use: Spraying, hauling, and manual handling of wet plaster must be performed in a controlled manner to minimize overapplication onto target and nontarget surfaces. While operational downfall (incidental plaster solids fallen from plaster application, handtroweling, and darbying) and some overspray will occur incidental to the plastering operation, it must be managed to prevent rewetting whenever possible. Shut off plaster gun when not applying material to target surface. When removing wet plaster from nontarget surfaces, such as foundations and raw wood, by handsprayer, minimize the amount of water used. Prior to pre-brown coat water blasting operation and prior to rain events, remove wet and dty operational downfall from rain exposed areas onsite or rake/shovel into piles at staging locations, such as underneath scaffolding or behind curb, and cover waste piles with plastic sheeting or equivalent. Drainage from water blasting must not discharge over sidewalks and curbs into gutters or stonn drain inlets. Use earthen berms or sand bags or equivalent behind curb of home sites to prevent runoff from water blasting operations. [If using paint, please see set of BMPs specific to Painters.] 28 Plastering Waste Management: Dispose of secured empty cement, colorant, and fiber bags as solid waste, or stage for disposal under cover or wrapped in plastic or equivalent.

Temporary operation staging locations must also be located away from drainages or waterways and from the dripline of retained trees whenever possible. Clean or cover any remaining operational staging location at the end of the workday or as agreed to in the scope of work. (See Caltrans BMPs Nos. WM-1 and WM-6 for more detail.) RF2- Sawdust/Sanding Management Temporary chop yards with mounted power saws (including saws, stair cutters, and roof cutters) must be located away from drainages and must be equipped with a sawdust collection box or bag that is maintained properiy. A sediment control BMP, such as straw wattle or an equivalent, should be placed on the downgradient perimeter of a chop yard. Individuals using handheld power saws should work in areas that are not exposed to rainfall whenever possible. Accumulations of handsawing debris outside the chop yard in areas that are exposed to rainfall must be removed or covered prior to the end of the workday and immediately in case of impending rain or as agreed to in the scope of work. Chop yards that are no longer active must be cleaned of lumber, carpentty waste, and sawdust prior to the end of the workday or covered overnight until it can be removed or as agreed to in the contract scope of work. (Caltrans BMP No. WM-5.) RFS- Sawcutting, Coring, and Potholing Management Temporaty masonty saws for cutting clay and concrete roof tiles must be located away from drainage(s), sensitive areas, and the dripline of any retained trees whenever possible. Sawing operations must be set up on an impermeable surface, such as plastic 43- sheeting with a sandbag berm or an equivalent placed around the chop yard perimeter. The masonry saw must have a cooling water collection system that is adequately sized and properiy maintained. Minimize water use. Dispose of masonry saw cooling wastewaters in a designated concrete washout facility or equivalent alternative washout facility (which includes portable disposal and containment systems). (Caltrans BMP No. WM-10.) RF4- Material Mixing Portable and manual mixing of mortar, grout and other cementitious ingredients must be performed over an impermeable surface with berming on the downgradient perimter, such as drop cloth, cardboard, or plastic sheeting over the ground or pavement with a sandbag berm, or an equivalent. Manual handling of wet, caustic materials, such as transporting material in a wheelbarrow from the mixer, must be performed in a controlled manner to prevent spills and drips. Spills to the ground or rain-exposed surfaces must cleaned up immediately. (Caltrans BMPs Nos. WM-2, WM-4, and WM-8.) RFS- Concrete Waste Management Handling of wet concrete and grout must be perfonned in a controlled manner to prevent spills and drips onto nontarget surface. Waste concrete and grout and the rinsate from portable mixers, associated tools, and protective clothing must be disposed of in a designated concrete washout facility or equivalent alternative washout facility (which includes portable containment and disposal systems). Minimize water use. Spills or overpours in rain-exposed areas must be removed prior to the end of the workday and priorto an impending rain event. (Caltrans BMPs Nos. WS-8 and NS-8.) .44, RF6- Material Use and Waste Management Operational staging of roof tar and grout on the ground must be placed on drop cloths, cardboard, plastic sheeting, or an equivalent. Nailguns and staplers must be used in a controlled manner to minimize nail and staple waste. Spills of roof tar or mortar to the ground or other rain-exposed surface must be cleaned up immediately and waste materials disposed of as described above. Unused material, spent equipment (including used buckets, scrapers, rags), and used protective sheeting from temporaty operational staging areas must be returned to designated storage bins/containers, placed properiy in either hazardous materials disposal bins or solid waste bins (for sheeting and dty grout/mortar), or removed from the site by the end of the workday and immediately prior to impending rain. Scrap and mortar waste remaining on the ground or on other rain- exposed surfaces must be removed and disposed of prior to the end of the workday or staged under roof or plastic cover (or an equivalent) until it can be removed or as agreed to in the contract scope of work. VVaste decking, nails, staples, boxes, and dried solid mortar waste that cannot be reused may be disposed of in a solid waste container or hauled away. Waste from hazardous materials use, such as asphaltic roof goop, must be disposed as hazardous waste, hauled offsite, or disposed of as agreed to in the contract scope of work. Scrap packaging, shingles, flashing, and other inert waste that cannot be reused may be disposed of onsite as solid waste or hauled away. Waste from most adhesive and caulk tubes, if completely empty, may also be disposed of onsite in solid waste containers. Wet solid mortar waste may be disposed in a designated concrete washout or an equivalent alternative washout facility (including portable containment and disposal systems) or hauled away. (Caltrans BMPs Nos. WM-2, WM-4 and WM-6.) RF7- Equipment/Tool Rinsing and Wastewater Management Minimize water and cleanser use. Rinsate and excess mortar and grouts from portable mixers and associated trowels and tools must be disposed of in designated concrete washout facilities or equivalent alternative washout facilities (including portable-disposal and containment systems) for disposal. Non-aqueous-based solvents are prohibited from use onsite unless ottienvise agreed to in the contract scope of work. Wastewater from cleaning and rinsing roof tar-laden tools and equipment must be collected and disposed of offsite. (Caltrans BMPs Nos. WM-8 and WM-6.) RFS- Handhelds and Equipment Fueling and Maintenance Only necessaty oiling and lubing that is required for the proper functioning of handheld equipment is allowed onsite. Limit the frequency of fueling and maintenance of any associated portable generators and compressors to that necessaty for proper functioning. Portable fuel and oil containers must be stored in a tub or equivalent device to avoid spills and leaks. Drop cloths, trays or an equivalent method must be used underneath handheld and associated portable equipment to avoid leaking fluids, fuels, oils, or grease onto the ground. Do not overspray aerosols to the ground or other rain- exposed surfaces. Clean up spills immediately and dispose of waste properiy. (Caltrans BMPs Nos. NS-9 and NS-10.) 45' RF9- Litter Control Do not throw pieces of lumber, shingles, sheathing, drip molding, roof tile, packaging, or other scrap materials into rain-exposed areas.

Inc. STORM WATER POLLUTION PREVENTION PLAN La Suvera CDP 04-16 BEST MANAGEMENT PRACTICES (POST-CONSTRUCTION) Introduction Craftsman Carlsbad I, LLC is required under the General Permit to ensure that adequate post construction BMPs are designed and implemented in order to reduce the amount of sediment and other pollutants that become available for transport by storm water or non-storm water runoff. In addition to this, the California Regional Water Quality Control Board for the San Diego Region approved Order Number 2001-01 (Order) on February 21, 2001. The Order outlines the storm water discharge requirements for municipal storm water systems, which drain "development" area from watersheds within: 1) the City of San Diego, 2) incorporated cities of San Diego County, and 3) San Diego Unified Port District. The City of Carisbad is identified as one of the municipal copermittees in the Order and, therefore, subject to its requirements. A requirement of the Order is the development, by co-permittees, of a model Standard Urban Storm Water Mitigation Plan (SUSMP). The SUSMP requires all pertinent new development and significant redevelopment projects to implement a combination of BMPs, including (1) source control BMPs and (2) structural treatment BMPs. Storm Water Management Plan Hunsaker & Associates San Diego, Inc. has prepared a Storm Water Management Plan (SWMP) for La Suvera, pursuant to requirements set forth in the City of Carlsbad's "Standard Urban Storm Water Mitigation Plan (SUSMP)." All calculations are consistent with criteria set forth by the Regional Water Quality Control Board's Order No. 2001-01, and the City of Carisbad SUSMP. The SWMP has been prepared to recommend the location of site Best Management Practices (BMPs), the determination of the 85"^ percentile runoff flow tributary to each individual treatment unit and the determination of storm water treatment unit sizing. The SWMP identifies the BMPs that will be implemented with this project, and contains information regarding their effectiveness and maintenance requirements. Maintenance responsibility is also discussed. Three (3) flow-based curb inlet filter BMPs will be placed at the three receiving storm drain inlets within the La Suvera site. The 85**^ percentile runoff will be treated in the proposed FloGard (or an equivalent approved curb inlet filter treatment unit) curb inlet filter units prior to discharging from the site. Prepared By: DI H:\SWPPP\2470/002^Main Hunsaker & Associates San Diego, IIK. STORM WATER POLLUTION PREVENTION PLAN La Suvera CDP 04-16 Source Control BMPs Source control BMPs include procedures to prevent pollutants from ever being deposited onsite, and to prevent soil from being exposed to the elements any longer than is necessary. These must be consistent with all City of Carisbad post-construction storm water management requirements, policies, and guidelines. Craftsman Carisbad I, LLC has considered site-specific and seasonal conditions when designing the control practices. Landscaping Manufactured slopes shall be landscaped with suitable ground cover or installed with an erosion control system. Homeowners should be educated as to the proper routine maintenance to landscaped areas including trimming, pruning, weeding, mowing, replacement or substitution of vegetation in ornamental and required landscapes. Per the RWQCB Order, the following landscaping activities are deemed unlawful and are thus prohibited: • Discharges of sediment, pet waste, vegetative clippings, or other landscaping or construction-related waste. Construction grounds and landscaped areas must be stabilized. Final stabilization for the purposes of submitting a Notice of Termination (NOT) is satisfied when the following steps are implemented: All soil disturbing activities are completed AND EITHER OF THE TWO FOLLOWING CRITERIA ARE MET: • A uniform vegetative cover with 70 percent coverage has been established OR: • Equivalent stabilization measures have been employed. These measures include the use of such BMPs as blankets, reinforced channel liners, soil cement, fiber matrices, geotextiles, or other erosion resistant soil coverings or treatments. • Where background native vegetation covers less than 100 percent of the surface, such as in arid areas, the 70 percent coverage criteria is adjusted as follows: If the native vegetation covers 50 percent of the ground surface, 70 percent of 50 percent (.70 X .50 = .35) would require 35 percent total uniform surface coverage. • Install front yard landscaping. • Landscape all slopes in accordance with the approved landscaping plan. • Maintain landscaping (via assignment to the HOA or to individual homeowners). Remove all vegetative waste and dispose of by composting in an appropriate location, by recycling in an approved facility, and/or by disposal in a landfill. Prepared By; DI H:\SWPPP\2470/002\Main Hunsaker & Associates San Diego, Inc. STORM WATER POLLUTION PREVENTION PLAN La Suvera CDP 04-16 Education Education of the homebuyers is an important way to help reduce pollutants in the post- construction project. • Provide homebuyers with information similar to the example in Appendix O as part of the new owner information package. Additional Considerations In addition, Craftsman Carlsbad I, LLC will implement the following BMPs where determined appropriate: (1) Installation of water efficient irrigation devices and use of reclaimed water on "common" areas throughout the development; (2) Interior drains; inlets, or sinks on private lots will be designed to not be connected to the storm drain system. (3) Roofing materials be composed of inert ingredients (e.g., plastic, tile) should be considered instead of materials (e.g., galvanized metal, copper, treated wood) likely to corrode and leach pollutants to storm water. (4) Energy dissipation devices, stabilized outfalls, high-flow bypasses, stream bank stabilization, and other structural controls necessary to prevent channel erosion. (5) Roof runoff from downspouts routed to pervious areas. (6) Driveways and sidewalks drained to pervious areas. (7) Driveways and sidewalk constructed from pervious materials such as pervious concrete, lattice, or grid pavement. (8) All onsite storm drain inlets, whether newly constructed or existing be stenciled with "Don't Dump - Drains to Ocean" (9) Trash: (a) Cover trash enclosures and/or recycling area(s), if feasible. (b) Use of impermeable materials for surfaces under dumpster areas. (c) Signage placed on the enclosure such as "No Hazardous Materials". (10) All front yards and private slopes will either be landscaped, hydro-seeded, or protected with fiber roll prior to home occupancy. Educational materials that discuss storm water pollution prevention will be provided to all homebuyers. Prepared By: DI H:\SWPPP\2470/002\Main Hiuisaker & Associates San Diego, IIK. STORM WATER POLLUTION PREVENTION PLAN La Suvera CDP 04-16 (11) Maintain landscaping via assignment to the HOA or to individual homeowners. Remove all vegetative waste and dispose of by composting in an appropriate location, by recycling in an approved facility, and/or by disposal in a landfill. (12) Inspect all landscape irrigation on a weekly basis to make sure that there are no broken sprinkler heads or pipes which are creating runoff and erosion) via assignment to the HOA or to individual homeowners). Other Ordinances In addition to being subject to the NPDES requirements, construction onsite is also controlled by the City of Carisbad Grading Ordinance, and Storm Water Management and Discharge Control Ordinance. Grading Ordinance The City of Carisbad Grading Ordinance, included as Appendix K, requires that permanent erosion control be provided by effective planting of slopes, and use of check dams, cribbing, rip-rap or other methods as necessary. These items must be shown on an erosion control plan. The BMPs proposed by this SWPPP meet or exceed the requirements ofthe grading ordinance. Municipal NPDES Permit The local governing agency is an active member of the NPDES Task Force. This agency has implemented a number of BMP programs, which include: • street sweeping • drainage ditch cleaning • used motor oil drop off • reduction in pesticide/fertilizer use • erosion prevention • education The post-construction BMPs specified in this SWPPP fall into the guidelines of the municipal permit.
