This area is impaired by Bacteria and sediment/siltation. To mitigate this problem this development will utilize "Fossil Filters" to remove any contaminates from on site runoff. June 4, 2003 3 TAIT & ASSOCIATES, INC. 3.0 CHARACTERIZATION OF PROJECT RUNOFF 3.1 Existing and Post-Construction Drainage 1 Water Management Pla11 (SWMP) -efp WEST COAST PRODUCTS, LLC CARLSBAD, CALIFORNIA The proposed project will not significantly alter drainage patterns on site. The site will utilize the existing point discharge locations. The proposed development results in an increase in the composite runoff coefficient from 0.83 to 0.85, as a result, the peak flow rate increases slightly from 2.81 cfs to 2.96 cfs. The increase in flow rate is insignificant. · A detailed description of the drainage patterns and flows are discussed in the Drainage Report submitted to the City of Carlsbad on February 5, 2003. This section is an excerpt from that report. The existing site drains via surface flow to the street right of way. The proposed site collects runoff is a series of catch basins for discharge under the sidewalk. Post-construction runoff will be directed the public right of way. This proposed development will not divert water from its original outlet points. The preliminary design of this system is included (See Attachment 2). Summaries of the post-construction water quality flows are included in Table 3.1. The flows were developed using the 85th Percentile Precipitation map developed by the County, which was obtained from the website http://www.co.san- diego.ca. us/dpw /land/flood.htm. Table 3.1 Post-Construction Water Quality Flows Basin# Development Condition Watershed Area 25-year peak flow Basin 1 Existing 0.31 0.77 Proposed 0.12 0.45 Basin 2 Existing 0.54 2.04 Prooosed 0.73 2.51 3.2 Post-Construction Expected Discharges There are no sampling data available for the existing site condition. In addition, the project is not expected to generate significant amounts of non-visible pollutants. However, the following constituents are commonly found on similar developments and could affect water quality: • Organic Compounds from solvents and hydrocarbons. • Oxygen demanding substances. • Oil, grease and hydrocarbons from vehicular traffic • Trash and debris deposited in drain inlets. • Pesticides, nutrients and herbicides from landscape maintenance. June 4, 2003 4 TAIT & ASSOCIATES, INC. 3.3 Soil Characteristics S ) Water Management Pla11 (SWMP) WEST COAST PRODUCTS, LLC CARLSBAD, CALIFORNIA The project area consists of soil group D with a minimum saturated infiltration rate of 6.3 mm/h. The project will not have slopes steeper than 2: 1. (Note: Information regarding soil conditions is also available in the Soil Survey, San Diego Area, California, US Department of Agriculture, 1973. 4.0 MITIGATION MEASURES TO PROTECT WATER QUALITY To address water quality for the project, BMPs will be implemented during construction and post-construction. 4.1 Construction BMPs A detailed description of the construction BMPs will be developed during the Grading Plan and Improvement Plan Engineering. Since the project is in the preliminary development phase only a listing of potential types of temporary BMPs are available. This includes the following: • Gravel bag Barrier • Gravel Bag Berms • Street Sweeping • Material Delivery and Storage • Storm Drain Inlet Protection • Spill Prevention and Control • Stockpile Management • Concrete Waste Management • Solid Waste Management • Water Conservation Practices • Stabilized Construction Entrance/Exit • Paving and Grinding Operations Construction BMPs for this project will be selected, constructed, and maintained so as to comply with all applicable ordinances and guidance documents. 4.2 Post-construction BMPs Pollutants of concern as noted in section 3 will be addressed through three types of BMPs. These types ofBMPs are site design, source control and treatment control. 4.2.1 Site Design BMPs Post-construction control practices to reduce or eliminate erosion and discharge of sediment and pollutants into the storm water systems include the following in accordance with the project plans and specifications: • Concrete curb and gutter • Paving • Landscaping June 4, 2003 5 TAIT & ASSOCIATES, INC. -• • Periodic maintenance by Owner Motor Fuel Dispensing Area r·---~. Water Ma11ageme11t Plan (SWMPJ ,,,IP WEST COAST PRODUCTS, LLC CARLSBAD, CALIFORNIA All paving near fuel dispensing areas will be Portland Cement Concrete extending at least 6-1/2 feet from the dispenser nozzles. A canopy protects the fueling area from direct runoff. The site is designed to prevent runoff from draining across the fueling slab. Under canopy spills are directed to two water quality inlets with "Fossil Filters". These sumps are equipped with a shut- off valve, which should remain in the closed position. " Landscaping Landscaped areas are designed to contain and allow absorption of runoff while following the designed flow paths. Plants shall be grouped with similar water requirements in order to reduce excess irrigation runoff and promote surface filtration. Commercial Vehicle Washing The covered carwash has provisions for recycling wash water. A sand/grit separator and clarifier system have been provided for recycling purposes. Trench drains intercept entrance and exit water and connect to this system. The follo\1\:'ing should be incorporated, where feasible, into ongoing operations: • All discharges and runoff from the proposed car wash operation shall be directed to the sewer system or to holding tanks. • As much waste water as feasible shall be captured and recycled using filters, oil/water separators with recyclable absorbents that absorb hydrocarbons but do not react with water, or reclamation systems. • Equipment, tanks and chemical containers shall be inspected for leaks regularly on a monthly basis. • Biodegradable soaps and chemicals should be used instead of solvent-based solutions. 4.2.2 Source Control BMPs Source control BMPs will consist of measures to prevent polluted runoff. This program will include an educational component directed to the owner and employees. The Owner should provide educational training for their employees in the proper use, handling and cleanup of all waste materials, pesticides, fertilizers, etc. while on the job. Qualified and experienced individuals shall provide training to each employee prior to allowing him/her to handle waste materials. Emergency response, spill prevention and this Storm Water Management Plan should be part of the Owner's educational program. June 4, 2003 6 TAIT & ASSOCIATES, INC. .. f ) Water Manageme11t Pla11 (SWMP) 1"P WEST COAST PRODUCTS, LLC CARLSBAD, CALIFORNIA The Owner will receive a set of brochures developed by the County's Environmental Health Department. These will include the following: • Stormwater Runoff Pollution Fact Sheet • Stormwater Runoff Pollution Prevention Tips for Business Owners • Stormwater Pollution Prevention for Landscaping In addition, storm drain inlets will be stenciled with a message warning citizens not to dump pollutants into the drains. 4.2.2.1 Activity Restrictions • Impervious surfaces including sidewalks, parking lots, driveways , etc. should be swept monthly. No hosing off into storm drains or adjacent property is allowed. • Cleanup is confined to using mop and bucket only. Use absorbent materials on small spills and remove them promptly. • Avoid over watering of landscape areas. ·, • This site has no vehicle repair facilities. Commercial car repairs on the property are prohibited. If any hazardous materials are stored on-site, the hazardous materials shall be disposed of in accordance with local regulations. Potential pollutants exposed to rainwater shall be covered. 4.2.2.2 Landscaping Landscape maintenance should be performed by professionals under contract. Biodegradable fertilizer shall be used whenever possible. Pesticides and fertilizers should be applied, by properly trained persons, at the minimum rate recommended by the manufacturer. • Unused pesticides and fertilizers should be stored in watertight containers in areas not exposed to rainfall or runoff. • Leaf blowers (if allowed) should be used to direct debris toward accessible collection areas for pickup. Debris should not be directed into the street or storm drains. • A voia over watering of landscape areas. • Prevent soil erosion by properly maintaining ground cover. 4.2.2.3 General Regulation & Permit Compliance The following general regulations are anticipated to be required based on the project's operations. Local governmental agencies should be contacted for further information and regulations. Local I Industrial Permits The Owner will need to comply with all local requirements regarding fuel dispensing and industrial waste discharge, if any. Check the local sewer agency's requirements for carwash discharge, industrial waste or storm water discharge permitting. June 4, 2003 7 TAIT & ASSOCIATES, INC. Title 22 Compliance ::r..~ Water Ma11ageme11t Plan (SWMP) BP WEST COAST PRODUCTS, LLC CARLSBAD, CALIFORNIA The Owner will ensure that its employees comply with Title 22 of the California Code of Regulations (CCR) and relevant sections of the California Health and Safety Code, Ch. 6.5, regarding hazardous waste management as enforced by San Diego County Department of Environmental Health on behalf of the State. Per Title 22, hazardous waste must be identified and permitted through the local permitting agency. Spill Contingency Plan Where necessary, a Spill Contingency Plan (Emergency Response Plan) should be prepared in conformance with San Diego County Department of Environmental Health guidelines. The plan should include provisions for stockpiling spill clean up and containment materials, notification to responsible agencies in case of a spill, disposal of cleanup materials after a spill and filing the required reports or other documentation related to spills. The "Fossil Filters" should be inspected after every spill and disposed of, if contaminated, per San Diego County's Hazardous Materials regulations for hydrocarbon-contaminated waste. Contact the local waste management company for additional assistance. Underground Storage Tank Compliance The Owner will need to comply with all related California Code of Regulations as enforced by San Diego County Department of Environmental Health, including C.C.R. Title 23 dealing with underground storage tanks and Ch. 6. 7 of the Health and Safety Code. In accordance with Title 23 C.C.R, a Monitoring and Response Plan should be prepared for the site. Uniform Fire Code Implementation Per Article 80 of the Uniform Fire Code, the Owner should keep information on the types and quantities of materials associated with on-site uses on file with the local Fire Department, updated annually, 4.2.2.4 Litter Control The Owner should implement trash management and litter control procedures aimed at reducing pollution of drainage water. It should consist of daily maintenance of parking lots and outside areas and requiring employees to deposit trash in waste containers with spill prevention features. The trash enclosure waste containers will be emptied weekly by a local commercial trash hauling company. The under canopy trash receptacles should be inspected daily, at a minimum, and emptied into the onsite waste container when full. June 4, 2003 8 TAIT & ASSOCIATES, INC. 4.2.3 Treatment Control BMPs -I ~ .• ..,;I Water Manageme11t Pla11 (SWMP) BP WEST COAST PRODUCTS, LLC CARLSBAD, CALIFORNIA The following treatment control BMPs will be implemented to address water quality: • "Fossil Filters" 4.2.3.1 "Fossil Filters" Catch basin inserts are small, passive, gravity-powered devices that are fitted below the grate of a drain inlet. When correctly designed and applied, they can intercept and contain significant amounts of litter, vegetation, petroleum hydrocarbons and coarse sediments. They target specific pollutants that have been identified as a priority at each site. They should be regarded as a part of a treatment train that incorporates source controls with in- line or conveyance controls, as well as end-of:.pipe solutions. All should function in a regulatory and educational framework aimed at pollution prevention as a primary source control before the first pollutant enters this system. 4.2.3.1.1 Appropriate Applications and Siting Constraints: "Fossil Filters" should be considered wherever site conditions allow for runoff without excessive debris ( e.g. Leaves, Sand, Trash) where flow velocities are not high enough to exceed filter capacity. FACTORS AFFECTING PRELIMINARY DESIGN: The efficiency of any filtration system is in direct proportion to the caliber of its maintenance program. Another system limitation is unsuitable installation sites. Examples of such sites would be areas with heavy leaf loading, areas next to sand or dirt piles and areas with permeable (non- hard) surface where soil and stones can be washed into the inlet.

The catch basins and piping should be cleaned whenever more than 20% of the volume capacity has been reduced by debris. Inspect roof drain inlets/outlets for any obstructions and clean as necessary. • Have sanitary sewer lines inspected for sediment buildup and clean as necessary. • Prior to the rainy season, September 30th, inspect and clean as necessary storm/roof drains. • After all storms, check drain inlets for any ponded water and take corrective actions as necessary. 5.2 "Fossil Filters" The operational and maintenance needs of a "Fossil Filter" are. • Regular sweeping and removal of debris. • Regular inspections. June4,2003 10 TAIT&ASSOCIATES,INC. • Cleaning out the insert. • Disposal of the collected pollutants and exposed absorbent. • Replenishment of absorbent material supply. Inspection Frequency S '"""\ Water Management Plan (SWMP) -~ WEST COAST PRODUCTS, LLC CARLSBAD, CALIFORNIA The installed devices should be inspected on a regular basis. The frequency of inspection should be based on pollutant loading, amount of debris, leaves, etc., and amount of runoff. Manufacturer recommendations include no less than three inspections per year. I Manufacturer guidelines for timing of inspections are: • For areas with a definite rainy season: Prior to and during the rainy season at a minimum. • For filters not subject to the elements (washracks, parking garages, etc.), inspections should be on a regular basis. The facility will be inspected and inspection visits will be completely documented: Functional Maintenance Functional maintenance has two components, preventive maintenance and corrective maintenance Preventive Maintenance Preventive maintenance activities to be instituted at all "Fossil Filter" inlets are: • Trash and Debris. During each inspection, debris and trash removal will be conducted to reduce the potential for inlet structures and other components from becoming clogged and inoperable during storm events. • Sediment Removal. Sediment accumulation, as part of the operation and maintenance program, will be monitored once a month during the dry season, after every large storm (0.50 inch), and monthly during the wet season. Specifically, if sediment interferes with flow or operation, the sediment will be removed. • Cleaning Insert. Insert devices must be cleaned out on a recurring basis. The . manufacturer recommends at least three cleanings per year -more in high exposure areas. June 4, 2003 11 TAIT & ASSOCIATES, INC. Corrective Maintenance )m Water Management Plan (SWMP) BP WEST COAST PRODUCTS, LLC CARLSBAD, CALIFORNIA Corrective maintenance is required on an emergency or non-routine basis to correct problems and to restore the intended operation and safe function of a "Fossil Filter". Corrective maintenance activities include: • Removal of Debris and Sediment. The collected debris and the exposed adsorbent, which should be placed in DOT approved drums, with proper handling and documentation, can usually be disposed of at a landfill. However, because disposal regulations vary by area, it is recommended that the persons disposing of the material contact their local regulatory agency and landfill to ensure compliance with local and state environmental regulations. 6.0 FISCAL RESOURCES The maintenance of post-construction BMP's will be the responsibility of the owner. Maintenance cost for "Fossil Filter" inserts is estimated at $1,000 per year 7.0 SUMMARY/CONCLUSIONS This SWMP has been prepared in accordance with the Watershed Protection, Stormwater Management, and Discharge Control Ordinance and the Stormwater Standards Manual. This SWMP has evaluated and addressed the potential pollutants associated with this project and their effects on water quality. A summary of the facts and findings associated with this project and the measures addressed by this SWMP is as follows: • The beneficial uses for the receiving wafers have been identified. None of these beneficial uses will be impaired or diminish due to the construction and operation of this project. • The Arco Project will not significantly alter total on site drainage flows. The discharge points will not be changed. • The proposed construction and post-construction BMP's address the mitigation measures to protect water quality and protection of water quality objectives and beneficial uses to the maximum extent practicable. • To further protect runoff quality a "Dead Sump" has been designed to intercept fuel s~ills or contaminated runoff from under the fueling station canopy. A valve will allow the owner to cutoff contaminated flow before it gets to the public right of way. The "Dead Sump" will then contain all emergency fuel spills and allow the owner to remove and dispose of in accordance with federal, state and local regulations. See Appendix C for "Dead Sump" detail.

Fossil Fi/ter™ is an effective tool in the efforts to reduce pollution of lakes. rivers. streams and oceans caused by contaminants borne in stormwater runoff. Within the United States. the federal Environmental Protection Agency (EPA) has mandated that states and cities implement Storm Water Pollution Prevention Programs (SWPPP) to curtail pollution from stormwater runoff. The EPA cites Best Available Technology (BAT) criteria for states and cities to use. Fossil Filter™ meets that BAT criteria · THE NEED FOR AN EFFECflVE MAINTENANCE PROGRAM Once installed. the Fossil Filtel""M becomes subject to the provisions of the EPA·s best Management Practices (BMP) dictates. According to the EPA. BMP includes the development of a plan to prevent pollution from stormwater runoff. A natural component of that plan is the establishment of an overall maintenance program. (In the absence of an established maintenance program. KriStar Enterprises cannot warrant the effectiveness of the J:ossil Filter™.) An effective maintenan~e program. where Fossil Filter"" is installed, should include the followi11g key components: 1. INSTALLATION RECORD At the time of installation. both the installer and owner must complete and sign the Fossil · FilterM Installation Record (See Example). The white copy is to remain on file with the owner, th_e yelfow copy i:nust be faxed or mailed to KriStar Enterprises. and the pink copy retained by the installer. 2. MAINnNANCE RECORD At the time of installation. the installer and/or owner must complete the top portion of the Fossil Filte.f"°'M Maintenance Record (See Example). This record is to remain on file with the owner so that he may accurately document the maintenance of the filters. ', To ensure compliance with EPA mandates, it is the responsibility of the owner to establish a maintenance program and maintain a record thereof. Again, without an established maintenance program. Kri5.tar Enterprises cannot warranty the effectiveness of the Fossil Filter"". 3.

Inspect the filter liner for serviceability. If called for, the filter body should be replaced. c. Check the condition of the adsorbent pouches and visually check the condition of the enclosed adsorbent. If the surface of the granules is more than 50% coated with a dark gray or black substance, the pouches should be replaced with new ones. d. Check for loose or missing nuts (on some models) and gaps between the filter and the inlet wall which would allow bypass of the filter during low flows .. e. The filter components should be replaced in the inlet and the grate replaced. 4. CLEANING OUT THE FLO-GARD INSERT: Regardless of the model of Flo-Gard insert, the devices must be cleaned out on a recurring basis. The manufacturer recommends at least three cleanings per year -more in high exposure areas. _ a. The Standard Flo-Gard, in most cases, can be cleaned out by removing the device from the inlet and dumping the contents into a DOT approved drum for later disposal. If the Fossil Rock pouches need to be changed, the time to change them is immediately after dumping and before the filter is replaced in the inlet. b. Because of weight, method of installation and so forth, the Flo-Gard High Capacity, Flo-Gard+Plus and the Perk Filter should be cleaned with the aid of a vactor truck. If necessary, the Fossil Rock pouches should be changed after the pollutants have been removed and-as the filter is being returned to service. 5. DISPOSAL OF THE COLLECTED POLL UT ANTS AND EXPOSED ADSORBENT: Note: As the generator, the landowner is ultimately responsible for the proper disposal of all materials collected and exposed adsorbent. The collected debris and the exposed adsorbent, which should be placed in DOT approved drums, with proper handling and documentation, can usually be disposed of at a landfill. However, because disposal regulations vary by area, it is recommended that the persons disposing of the material contact their local regulatory agency and landfill to ensure compliance with local and state environmental regulations. 6. REPLENISHMENT OF ADSORBENT MATERIAL SUPPLY: Persons responsible for maintaining Flo-Gard catch basin insert filters should keep a supply of Fossil Rock adsorbent pouches on hand to replace overly exposed pouches. Note: Fossil Rock adsorbent is the only tested and approved material for use in Kristar's line of filters. As the manufacturer, Kristar cannot guarantee a similar level of filter efficiency with the use of other materials. If you have questions about Kristar's products or Fossil Rock adsorbent, please call KriStar Enterprises, Inc. at (800) 579-8819.

However, once the devices were installed, there was no requirement for follow-on maintenance or service. Pollutants captured during a rain event remained in the devices until subsequent rain events and then either the devices became plugged-up or the pollutants were flushed on downstream and eventually found their way into the river, stream, ocean, etc. Regulators and governmental agencies are now very diligent in requiring that installed devices be services on a regular basis. DRAINAGE PROTECTION SYSTEMS (DPS) "Our Business Is Maintenance of Stormwater Drainage Inlets - And We Are Good At It" DPS IN ACTION! Drainage Protection Systems (DPS), a dba of KriStar Enterprises, Inc., is in the business of servicing all catch basin filtration systems, stormwater interceptors, oil/water separators and tanks of all sorts, as well as stormwater inlets without devices installed. DPS's highly qualified technicians: • Are certified and equipped for, and experienced in, confined space operations. • Maintain service recoreds on each and every service of each and every site. • Relieve the landowner of the burden of compliance with environmental laws and record-keeping. • Relieve the landowner of the burden of having to spend time and resources to maintain the systems and to properly dispose of the exposed materials. Note: For storm drain maintenance services, contact Drainage Protection Systems (DPS) at (800) 950-8826 Reasons for servicing storm drain systems: 1. It's the law: Federal EPA's 1987 Clean Water Act (33 U.S.C. 1251 et seq., Section 402(P), as amended) and state and local enabling laws require that systems be maintained. 2. To protect the environment. Pollution of our water resources by harmful contaminants that gain entry through the storm drain system is a major problem that must be solved. The Clean Water Act aggressively addresses the problem. uui:ui;iii:Ic:S 1ur 1Y1aimenance or .t'lo-liara ancl .t<io-Gard+.Plus ,- Ffo-GardrM Maintenance MAINTENANCE GUIDELINES FOR FLO-GARD™ INSERTS When installed in a drainage inlet catch basin or tank, Flo-Gard™ products are an effective tool in the effort to reduce pollution of lakes, rivers, streams and oceans caused by pollutants borne in urban water runoff. Within the United States, the federal Environmental Protection Agency (EPA) has, via the Clean Water Act (CWA), mandated that states and cities implement Storm Water Pollution Prevention Programs (SWPPP) to curtail pollution from water runoff. The EPA cites Best Available Technology (BAT) criteria for states and cities to use. Flo-Gard™ meet the BAT criteria. Once installed, the Flo-Gard™ becomes subject to the provisions of the CWA's Best Management Practices (BMP) dictates. According to the EPA, BMP's include the development of a plan to prevent pollution from urban water runoff. Responsibility for developing the plan ultimately rests with the landowner. A natural component of any plan is the establishment of an overall maintenance program. Note: Without an established maintenance program, KriStar Enterprises cannot warrant the effectiveness of their products. An effective maintenance program should include the following key components: 1. REGULAR SWEEPING AND REMOVAL OF DEBRIS: Vehicle parking lots, corporation yards, and so forth should be swept on a regular basis. Sediment and debris (litter, leaves, papers and cans, etc.) within the area, especially around the drainage inlet, should be collected and removed. The frequency of sweeping should be based on the amount of sediment and debris generated. 2. REGULAR INSPECTIONS: The installed devices should be inspected on a regular basis. The frequency of inspection should be based on pollutant loading, amount of debris, leaves, etc., and amount of runoff. Manufacturer recommendations include no less than three inspections per year. Manufacturer guidelines for timing of inspections are: a. For areas with a definite rainy season: Prior to and during the rainy season. b. For areas subject to year-round rainfall: On a recurring (preferably scheduled) basis. c. For areas with winter snow and summer rain: Prior to and just after the snow season and during the summer rain season. d. For filters not subject to the elements (washracks, parking garages, etc.), inspections should be on a regular basis. 3. CONDUCT OF THE VISUAL INSPECTION: While the design of the various models of the Flo-Gard inserts (Flo-Gard+Plus, High Capacity and Standard) differ, the basic procedures for the visual inspection are similar. a. Broom sweep around the inlet and remove the inlet grate. -i..--• , __ . Page 1 of2 • / l!I .KriStar Service for storr.o,.drain and catch basin filtration systems, "-"!water separators, and ...
