The project is located at 79087 Ahmanson Lane, La Quinta, CA 92253 in the City of La Quinta. The site is approximately 3.0 acres, practice range adjacent, and includes the installation of a modular building unit to house a temporary clubhouse, vehicle parking lot, overflow parking and covered golf cart parking. The temporary clubhouse and site improvements will be utilized for a time frame of approximately two to three years. The total size of disturbed area is 2.4 acres. Pre- project quantity of impervious surface is zero acres (0%); Post-project quantity of impervious surface is 0.8 acre (20%). Site sheet flows northwesterly then northerly to low points where it percolates, evapotranspires and infiltrates. Portion of the site sheet flows easterly towards existing curb at westerly side of Ahmanson Lane, flow southerly to a catch basin and end up at the existing Drywell, where it percolates and infiltrate. Typical activities associated with this type of development include incoming and outgoing vehicle traffic, events and parking, landscape maintenance, use and maintenance of golf course vehicles, and use of trash/recycle bins. The potential pollutants generated by this land use type include sediments, nutrients, organic compounds, trash and debris, bacteria and viruses, oil and grease, and metals.

Hydrologic Conditions of Concern Local Jurisdiction Requires On-Site Retention of Urban Runoff: Yes The project will be required to retain urban runoff onsite in conformance with local ordinance (See Table 6 of the WQMP Guidance document, "Local Land use Authorities Requiring Onsite Retention of Stormwater"). This section does not need to be completed; however, retention facility design details and sizing calculations must be included in Appendix F. No This section must be completed. This Project meets the following condition: Condition A: 1) Runoff from the Project is discharged directly to a publicly-owned, operated and maintained MS4 or engineered and maintained channel, 2) the discharge is in full compliance with local land use authority requirements for connections and discharges to the MS4 (including both quality and quantity requirements), 3) the discharge would not significantly impact stream habitat in proximate Receiving Waters, and 4) the discharge is authorized by the local land use authority. Condition B: The project disturbs less than 1 acre and is not part of a larger common plan of development that exceeds 1 acre of disturbance. The disturbed area calculation must include all disturbances associated with larger plans of development. Condition C: The project's runoff flow rate, volume, velocity and duration for the post-development condition do not exceed the pre-development condition for the 2- year, 24-hour and 10-year 24-hour rainfall events. This condition can be achieved by, where applicable, complying with the local land use authority's on-site retention ordinance, or minimizing impervious area on a site and incorporating other Site- Design BMP concepts and LID/Site Design BMPs that assure non-exceedance of pre-development conditions. This condition must be substantiated by hydrologic modeling methods acceptable to the local land use authority. None: Refer to Section 3.4 of the Whitewater River Region WQMP Guidance document for additional requirements. Supporting engineering studies, calculations, and reports are included in Appendix C. 2 year – 24 hour 10 year – 24 hour Precondition Post-condition Precondition Post-condition Discharge (cfs) Velocity (fps) Volume (cubic feet) Duration (minutes) 2015 Whitewater River Region WQMP SilverRock Resort (PM 37207) – Temporary Clubhouse November 2017 1-9 V. Best Management Practices This project implements Best Management Practices (BMPs) to address the Pollutants of Concern that may potentially be generated from the use of the Project site plus existing site area(s). These BMPs have been selected and implemented to comply with Section 3.5 of the WQMP Guidance document, and consist of Site Design BMP concepts, Source Control, LID/Site Design and, if/where necessary, Treatment Control BMPs as described herein. V.1 SITE DESIGN BMP CONCEPTS, LID/SITE DESIGN AND TREATMENT CONTROL BMPS Local Jurisdiction Requires On-Site Retention of Urban Runoff: Yes The project will be required to retain Urban Runoff onsite in conformance with local ordinance (See Table 6 of the WQMP Guidance document, "Local Land use Authorities Requiring Onsite Retention of Stormwater). The LID/Site Design measurable goal has thus been met (100%), and Sections V.1.A and V.1.B do not need to be completed; however, retention facility design details and sizing calculations must be included in Appendix F, and '100%' should be entered into Column 3 of Table 6 below. No Section V.1 must be completed. This section of the Project-Specific WQMP documents the LID/Site Design BMPs and, if/where necessary, the Treatment Control BMPs that will be implemented on the project to meet the requirements detailed within Section 3.5.1 of the WQMP Guidance document. Section 3.5.1 includes requirements to implement Site Design Concepts and BMPs, and includes requirements to address Pollutants of Concern with BMPs. Further, sub-section 3.5.1.1 specifically requires that Pollutants of Concern be addressed with LID/Site Design BMPs to the extent feasible. LID/Site Design BMPs are those BMPs listed within Table 2 below which promote retention and/or feature a natural treatment mechanism; off-site and regionally-based BMPs are also LID/Site Design BMPs, and therefore count towards the measurable goal, if they fit these criteria. This project incorporates LID/Site Design BMPs to fully address the Treatment Control BMP requirement where and to the extent feasible. If and where it has been acceptably demonstrated to the local land use authority that it is infeasible to fully meet this requirement with LID/Site Design BMPs, Section V.1.B (below) includes a description of the conventional Treatment Control BMPs that will be substituted to meet the same requirements. In addressing Pollutants of Concern, BMPs are selected using Table 2 below. 2015 Whitewater River Region WQMP SilverRock Resort (PM 37207) – Temporary Clubhouse November 2017 1-10 Table 2.

Implementation of Site Design BMP Concepts Included Brief Reason for BMPs Indicated as No or N/A Design Concept Technique Specific BMP Yes No N/A Site Design BMP Concept 1 Minimize Urban Runoff, Minimize Impervious Footprint, and Conserve Natural Areas (See WQMP Section 3.5.1.3) Conserve natural areas by concentrating or clustering development on the least environmentally sensitive portions of a site while leaving the remaining land in a natural, undisturbed condition. Conserve natural areas by incorporating the goals of the Multi-Species Habitat Conservation Plan or other natural resource plans. Preserve natural drainage features and natural depressional storage areas on the site. Maximize canopy interception and water conservation by preserving existing native trees and shrubs, and planting additional native or drought tolerant trees and large shrubs. Use natural drainage systems. Where applicable, incorporate Self-Treating Areas Where applicable, incorporate Self-Retaining Areas Increase the building floor to area ratio (i.e., number of stories above or below ground). Proposed building 1-story portable structure Construct streets, sidewalks and parking lot aisles to minimum widths necessary, provided that public safety and a walkable environment for pedestrians are not compromised. Reduce widths of streets where off-street parking is available. Minimize the use of impervious surfaces, such as decorative concrete, in the landscape design. 2015 Whitewater River Region WQMP SilverRock Resort Temporary Clubhouse (Portion of Parcel 1, PM 37207) November 2017 1-13 Other comparable and equally effective Site Design BMP concept(s) as approved by the local land use authority (Note: Additional narrative required to describe BMP and how it addresses site design concept). Almost half of the drainage area will be draining to existing curb and gutter that flows towards an existing catch basin and eventually ended up to an existing Dry Well. The other half drains northerly and southerly towards an existing lower Golf Tees and/or existing lake. 2015 Whitewater River Region WQMP SilverRock Resort Temporary Clubhouse (Portion of Parcel 1, PM 37207) November 2017 1-14 Table 3. Site Design BMP Concepts (continued) Included Brief Reason for Each BMP Indicated as No or N/A Design Concept Technique Specific BMP Yes No N/A Site Design BMP Concept 2 Minimize Directly Connected Impervious Area (See WQMP Section 3.5.1.4) Design residential and commercial sites to contain and infiltrate roof runoff, or direct roof runoff to landscaped swales or buffer areas. Drain impervious sidewalks, walkways, trails, and patios into adjacent landscaping. Incorporate landscaped buffer areas between sidewalks and streets. No sidewalks and streets for this project. Use natural or landscaped drainage swales in lieu of underground piping or imperviously lined swales. Where soil conditions are suitable, use perforated pipe or gravel filtration pits for low flow infiltration. No perforated pipe or gravel filtration pits are used. Maximize the permeable area by constructing walkways, trails, patios, overflow parking, alleys, driveways, low-traffic streets, and other low-traffic areas with open-jointed paving materials or permeable surfaces such as pervious concrete, porous asphalt, unit pavers, and granular materials. Use one or more of the following: Rural swale system: street sheet flows to landscaped swale or gravel shoulder, curbs used at street corners, and culverts used under driveways and street crossings. No curb or streets used for this project. Urban curb/swale system: street slopes to curb; periodic swale inlets drain to landscaped swale or biofilter. No curb or streets used for this project. Dual drainage system: first flush captured in street catch basins and discharged to adjacent vegetated swale or gravel shoulder; high flows connect directly to MS4s. Other comparable and equally effective Site Design BMP concept(s) as approved by the local land use authority (Note: Additional narrative required to describe BMP and how it addresses site design concept). Almost half of the drainage area will be draining to existing curb and gutter that flows towards an existing catch basin and eventually ended up to an existing Dry Well. The other half drains northerly and southerly towards an existing lower Golf Tees and/or existing lake. Use one or more of the following for design of driveways and private residential parking areas: 2015 Whitewater River Region WQMP SilverRock Resort Temporary Clubhouse (Portion of Parcel 1, PM 37207) November 2017 1-15 Included Brief Reason for Each BMP Indicated as No or N/A Design Concept Technique Specific BMP Yes No N/A Design driveways with shared access, flared (single lane at street), or wheel strips (paving only under the tires). Uncovered temporary or guest parking on residential lots paved with a permeable surface, or designed to drain into landscaping. No temporary or guest parking on residential lots. Temporary parking areas for this project are paved with compacted Class II base-consider as partly pervious. 2015 Whitewater River Region WQMP SilverRock Resort Temporary Clubhouse (Portion of Parcel 1, PM 37207) November 2017 1-16 Table 3. Site Design BMP Concepts (continued) Included Brief Reason for Each BMP Indicated as No or N/A Design Concept Technique Specific BMP Yes No N/A Site Design BMP Concept 2 (cont'd) Minimize Directly Connected Impervious Area (See WQMP Section 3.5.1.4) Other comparable and equally effective Site Design BMP concept(s) as approved by the local land use authority (Note: Additional narrative required to describe BMP and how it addresses site design concept). Almost half of the drainage area will be draining to existing curb and gutter that flows towards an existing catch basin and eventually ended up to an existing Dry Well. The other half drains northerly and southerly towards an existing lower Golf Tees and/or existing lake. Use one or more of the following for design of parking areas: Where landscaping is proposed in parking areas, incorporate parking area landscaping into the drainage design. Overflow parking (parking stalls provided in excess of the Permittee's minimum parking requirements) may be constructed with permeable pavement. Other comparable and equally effective Site Design BMP (or BMPs) as approved by the local land use authority (Note: Additional narrative required describing BMP and how it addresses site design concept). Temporary parking areas for this project are paved with compacted Class II base-consider as partly pervious. 2015 Whitewater River Region WQMP SilverRock Resort Temporary Clubhouse (Por. of Parcel 1, PM 37207) November 2017 1-17 Project Site Design BMP Concepts: Most of the site will sheet flow northwesterly and northerly towards existing low-lying points along the golf course where it percolates, evapotranspires, and infiltrates within existing infiltration trench. The other portion will drain easterly towards existing curb in the street, along Ahmanson Lane, then collected by existing catch basin, southerly of the project and eventually drain into existing Dry Well where it percolates and infiltrates. This project will retain the 100% 100-year “pre-developed” and “post-developed” conditions. Hence, it satisfies the local ordinance requirement for 100% on-site retention for the 100-year, 24 hour storm event.

Due to the type of work or the materials involved, many activities that occur either at a municipal facility or as a part of municipal field programs have the potential for accidental spills and leaks. Proper spill response planning and preparation can enable municipal employees to effectively respond to problems when they occur and minimize the discharge of pollutants to the environment. Approach An effective spill response and control plan should include: - Spill/leak prevention measures; - Spill response procedures; - Spill cleanup procedures; - Reporting; and - Training A well thought out and implemented plan can prevent pollutants from entering the storm drainage system and can be used as a tool for training personnel to prevent and control future spills as well. Pollution Prevention Develop and implement a Spill Prevention Control and Response Plan. The plan should include: Objectives Cover Contain Educate Reduce/Minimize Product Substitution Targeted Constituents Sediment Nutrients Trash Metals Bacteria Oil and Grease Organics Oxygen Demanding SC-11 Spill Prevention, Control & Cleanup 2 of 7 California Stormwater BMP Handbook January 2003 Municipal www.cabmphandbooks.com - A description of the facility, the address, activities and materials involved - Identification of key spill response personnel - Identification of the potential spill areas or operations prone to spills/leaks - Identification of which areas should be or are bermed to contain spills/leaks - Facility map identifying the key locations of areas, activities, materials, structural BMPs, etc. - Material handling procedures - Spill response procedures including: - Assessment of the site and potential impacts - Containment of the material - Notification of the proper personnel and evacuation procedures - Clean up of the site - Disposal of the waste material and - Proper record keeping Product substitution – use less toxic materials (i.e. use water based paints instead of oil based paints) Recycle, reclaim, or reuse materials whenever possible. This will reduce the amount of materials that are brought into the facility or into the field. Suggested Protocols Spill/Leak Prevention Measures If possible, move material handling indoors, under cover, or away from storm drains or sensitive water bodies. Properly label all containers so that the contents are easily identifiable. Berm storage areas so that if a spill or leak occurs, the material is contained. Cover outside storage areas either with a permanent structure or with a seasonal one such as a tarp so that rain can not come into contact with the materials. Check containers (and any containment sumps) often for leaks and spills. Replace containers that are leaking, corroded, or otherwise deteriorating with containers in good condition. Collect all spilled liquids and properly dispose of them. Spill Prevention, Control & Cleanup SC-11 January 2003 California Stormwater BMP Handbook 3 of 7 Municipal www.cabmphandbooks.com Store, contain and transfer liquid materials in such a manner that if the container is ruptured or the contents spilled, they will not discharge, flow or be washed into the storm drainage system, surface waters, or groundwater. Place drip pans or absorbent materials beneath all mounted taps and at all potential drip and spill locations during the filling and unloading of containers. Any collected liquids or soiled absorbent materials should be reused/recycled or properly disposed of. For field programs, only transport the minimum amount of material needed for the daily activities and transfer materials between containers at a municipal yard where leaks and spill are easier to control. If paved, sweep and clean storage areas monthly, do not use water to hose down the area unless all of the water will be collected and disposed of properly. Install a spill control device (such as a tee section) in any catch basins that collect runoff from any storage areas if the materials stored are oil, gas, or other materials that separate from and float on water. This will allow for easier cleanup if a spill occurs. If necessary, protect catch basins while conducting field activities so that if a spill occurs, the material will be contained. Training Educate employees about spill prevention, spill response and cleanup on a routine basis. Well-trained employees can reduce human errors that lead to accidental releases or spills: - The employees should have the tools and knowledge to immediately begin cleaning up a spill if one should occur. - Employees should be familiar with the Spill Prevention Control and Countermeasure Plan if one is available. Training of staff from all municipal departments should focus on recognizing and reporting potential or current spills/leaks and who they should contact. Employees responsible for aboveground storage tanks and liquid transfers for large bulk containers should be thoroughly familiar with the Spill Prevention Control and Countermeasure Plan and the plan should be readily available. Spill Response and Prevention Identify key spill response personnel and train employees on who they are. Store and maintain appropriate spill cleanup materials in a clearly marked location near storage areas; and train employees to ensure familiarity with the site’s spill control plan and/or proper spill cleanup procedures. Locate spill cleanup materials, such as absorbents, where they will be readily accessible (e.g. near storage and maintenance areas, on field trucks). SC-11 Spill Prevention, Control & Cleanup 4 of 7 California Stormwater BMP Handbook January 2003 Municipal www.cabmphandbooks.com Follow the Spill Prevention Control and Countermeasure Plan if one is available. If a spill occurs, notify the key spill response personnel immediately. If the material is unknown or hazardous, the local fire department may also need to be contacted. If safe to do so, attempt to contain the material and block the nearby storm drains so that the area impacted is minimized. If the material is unknown or hazardous wait for properly trained personnel to contain the materials. Perform an assessment of the area where the spill occurred and the downstream area that it could impact. Relay this information to the key spill response and clean up personnel. Spill Cleanup Procedures Small non-hazardous spills - Use a rag, damp cloth or absorbent materials for general clean up of liquids - Use brooms or shovels for the general clean up of dry materials - If water is used, it must be collected and properly disposed of. The wash water can not be allowed to enter the storm drain. - Dispose of any waste materials properly - Clean or dispose of any equipment used to clean up the spill properly Large non-hazardous spills - Use absorbent materials for general clean up of liquids - Use brooms, shovels or street sweepers for the general clean up of dry materials - If water is used, it must be collected and properly disposed of. The wash water can not be allowed to enter the storm drain. - Dispose of any waste materials properly - Clean or dispose of any equipment used to clean up the spill properly For hazardous or very large spills, a private cleanup company or Hazmat team may need to be contacted to assess the situation and conduct the cleanup and disposal of the materials. Chemical cleanups of material can be achieved with the use of absorbents, gels, and foams. Remove the adsorbent materials promptly and dispose of according to regulations. If the spilled material is hazardous, then the used cleanup materials are also hazardous and must be sent to a certified laundry (rags) or disposed of as hazardous waste. Reporting Report any spills immediately to the identified key municipal spill response personnel. Spill Prevention, Control & Cleanup SC-11 January 2003 California Stormwater BMP Handbook 5 of 7 Municipal www.cabmphandbooks.com Report spills in accordance with applicable reporting laws. Spills that pose an immediate threat to human health or the environment must be reported immediately to the Office of Emergency Service (OES) Spills that pose an immediate threat to human health or the environment may also need to be reported within 24 hours to the Regional Water Quality Control Board. Federal regulations require that any oil spill into a water body or onto an adjoining shoreline be reported to the National Response Center (NRC) at 800-424-8802 (24 hour) After the spill has been contained and cleaned up, a detailed report about the incident should be generated and kept on file (see the section on Reporting below). The incident may also be used in briefing staff about proper procedures Other Considerations State regulations exist for facilities with a storage capacity of 10,000 gallons or more of petroleum to prepare a Spill Prevention Control and Countermeasure Plan (SPCC) Plan (Health & Safety Code Chapter 6.67). State regulations also exist for storage of hazardous materials (Health & Safety Code Chapter 6.95), including the preparation of area and business plans for emergency response to the releases or threatened releases. Consider requiring smaller secondary containment areas (less than 200 sq. ft.) to be connected to the sanitary sewer, if permitted to do so, prohibiting any hard connections to the storm drain. Requirements Costs Will vary depending on the size of the facility and the necessary controls. Prevention of leaks and spills is inexpensive. Treatment and/or disposal of wastes, contaminated soil and water is very expensive Maintenance This BMP has no major administrative or staffing requirements. However, extra time is needed to properly handle and dispose of spills, which results in increased labor costs Supplemental Information Further Detail of the BMP Reporting Record keeping and internal reporting represent good operating practices because they can increase the efficiency of the response and containment of a spill. A good record keeping system helps the municipality minimize incident recurrence, correctly respond with appropriate containment and cleanup activities, and comply with legal requirements. SC-11 Spill Prevention, Control & Cleanup 6 of 7 California Stormwater BMP Handbook January 2003 Municipal www.cabmphandbooks.com A record keeping and reporting system should be set up for documenting spills, leaks, and other discharges, including discharges of hazardous substances in reportable quantities. Incident records describe the quality and quantity of non-stormwater discharges to the storm drain. These records should contain the following information: Date and time of the incident Weather conditions Duration of the spill/leak/discharge Cause of the spill/leak/discharge Response procedures implemented Persons notified Environmental problems associated with the spill/leak/discharge Separate record keeping systems should be established to document housekeeping and preventive maintenance inspections, and training activities. All housekeeping and preventive maintenance inspections should be documented. Inspection documentation should contain the following information: The date and time the inspection was performed Name of the inspector Items inspected Problems noted Corrective action required Date corrective action was taken Other means to document and record inspection results are field notes, timed and dated photographs, videotapes, and drawings and maps. Examples The City of Palo Alto includes spill prevention and control as a major element of its highly effective program for municipal vehicle maintenance shops.

Implementing the following management practices can help prevent fuel spills and leaks. Approach Reduce potential for pollutant discharge through source control pollution prevention and BMP implementation. Successful implementation depends on effective training of employees on applicable BMPs and general pollution prevention strategies and objectives. Pollution Prevention Use properly maintained offsite fueling stations whenever possible. These businesses are better equipped to handle fuel and spills properly. Educate employees about pollution prevention measures and goals Focus pollution prevention activities on containment of spills and leaks, most of which may occur during liquid transfers. Suggested Protocols General "Spot clean" leaks and drips routinely. Leaks are not cleaned up until the absorbent is picked up and disposed of properly. Objectives Cover Contain Educate Reduce/Minimize Targeted Constituents Sediment Nutrients Trash Metals Bacteria Oil and Grease Organics Oxygen Demanding SC-20 Vehicle and Equipment Fueling 2 of 6 California Stormwater BMP Handbook January 2003 Municipal www.cabmphandbooks.com Label drains within the facility boundary, by paint/stencil (or equivalent), to indicate whether they flow to an oil/water separator, directly to the sewer, or to a storm drain. Labels are not necessary for plumbing fixtures directly connected to the sanitary sewer but may be useful to help eliminate confusion about where the drain leads. Post signs to remind employees not to top off the fuel tank when filling and signs that ban employees from changing engine oil or other fluids at that location. Report leaking vehicles to fleet maintenance. Install inlet catch basin equipped with a small sedimentation basin or grit chamber to remove large particles from stormwater in highly impervious areas. Proper maintenance of these devices is necessary. Accumulated non-contaminated stormwater (e.g., in a secondary containment) should be released prior to next storm. Ensure the following safeguards are in place: - Overflow protection devices on tank systems to warn the operator to automatically shutdown transfer pumps when the tank reaches full capacity. - Protective guards around tanks and piping to prevent vehicle or forklift damage. - Clearly tagging or labeling all valves to reduce human error. - Automatic shut off for severed fuel hoses. Fuel Dispensing Areas Maintain clean fuel-dispensing areas using dry cleanup methods such as sweeping for removal of litter and debris, or use of rags and absorbents for leaks and spills. Do not wash down areas with water. Fit underground storage tanks with spill containment and overfill prevention systems meeting the requirements of Section 2635(b) of Title 23 of the California Code of Regulations. Fit fuel dispensing nozzles with "hold-open latches" (automatic shutoffs) except where prohibited by local fire departments. Post signs at the fuel dispenser or fuel island warning vehicle owners/operators against "topping off" of vehicle fuel tanks. Design fueling area to prevent stormwater runoff and spills. Cover fueling area with an overhanging roof structure or canopy so that precipitation cannot come in contact with the fueling area and if possible use a perimeter drain or slope pavement inward with drainage to a blind sump (must be properly maintained and water properly disposed of); pave area with concrete rather than asphalt. Vehicle and Equipment Fueling SC-20 January 2003 California Stormwater BMP Handbook 3 of 6 Municipal www.cabmphandbooks.com Apply a suitable sealant that protects the asphalt from spilled fuels in areas where covering is infeasible and the fuel island is surrounded by pavement. Install vapor recovery nozzles to help control drips as well as air pollution. Use secondary containment when transferring fuel from the tank truck to the fuel tank. Cover storm drains in the vicinity during transfer. Outdoor Waste Receptacle Area Spot clean leaks and drips routinely to prevent runoff of spillage. Minimize the possibility of stormwater pollution from outside waste receptacles by using an effective combination of the following: - use only watertight waste receptacle(s) and keep the lid(s) closed, or - grade and pave the waste receptacle area to prevent runon of stormwater, or - install a roof over the waste receptacle area, or - install a low containment berm around the waste receptacle area, or - use and maintain drip pans under waste receptacles. Containment areas and drip pans must be properly maintained and collected water disposed of properly (e.g., to sanitary sewer). Several drip pans should be stored in a covered location near outdoor waste receptacle area so that they are always available, yet protected from precipitation when not in use. Post “no littering” signs. Air/Water Supply Area Minimize the possibility of stormwater pollution from air/water supply areas by implementing an effective combination of the following: - spot clean leaks and drips routinely to prevent runoff of spillage, or - grade and pave the air/water supply area to prevent runon of stormwater, or - install a roof over the air/water supply area, or - install a low containment berm around the air/water supply area. Maintain containment areas and dispose of contaminated water properly (e.g., to sanitary sewer). Inspection Aboveground Tank Leak and Spill Control: - Check for external corrosion and structural failure. SC-20 Vehicle and Equipment Fueling 4 of 6 California Stormwater BMP Handbook January 2003 Municipal www.cabmphandbooks.com - Check for spills and overfills due to operator error. - Check for failure of piping system. - Check for leaks or spills during pumping of liquids or gases from truck or rail car to a storage facility or vice versa. - Visually inspect new tank or container installation for loose fittings, poor welding, and improper or poorly fitted gaskets. - Inspect tank foundations, connections, coatings, and tank walls and piping system. Look for corrosion, leaks, cracks, scratches, and other physical damage that may weaken the tank or container system. - Periodically, integrity testing should be conducted by a qualified professional. Inspect and clean, if necessary, storm drain inlets and catch basins within the facility boundary before October 1 each year. Training Train all employees upon hiring and annually thereafter on proper methods for handling and disposing of waste. Make sure that all employees understand stormwater discharge prohibitions, wastewater discharge requirements, and these best management practices. Train employees on proper fueling and cleanup procedures. Use a training log or similar method to document training. Ensure that employees are familiar with the site’s spill control plan and/or proper spill cleanup procedures. Spill Response and Prevention Keep your Spill Prevention Control and Countermeasure (SPCC) Plan up-to-date. Place stockpiles of spill cleanup materials where they are readily accessible. Use adsorbent materials on small spills and general cleaning rather than hosing down the area. Remove the adsorbent materials promptly and dispose properly. Store portable absorbent booms (long flexible shafts or barriers made of absorbent material) in unbermed fueling areas. Report spills promptly. Install an oil/water separator and connect to the sanitary sewer (if allowed), if a dead-end sump is not used to collect spills. Other Considerations Carry out all federal and state requirements regarding underground storage tanks, or install above ground tanks. Vehicle and Equipment Fueling SC-20 January 2003 California Stormwater BMP Handbook 5 of 6 Municipal www.cabmphandbooks.com Requirements Costs The retrofitting of existing fueling areas to minimize stormwater exposure or spill runoff can be expensive. Good design must occur during the initial installation. Extruded curb along the “upstream” side of the fueling area to prevent stormwater runon is of modest cost. Maintenance Clean oil/water separators at appropriate intervals. Keep ample supplies of spill cleanup materials onsite. Inspect fueling areas, storage tanks, catch basin inserts, containment areas, and drip pans on a regular schedule. Supplemental Information Design Considerations Designing New Installations The elements listed below should be included in the design and construction of new or substantially remodeled facilities. Fuel Dispensing Areas Fuel dispensing areas must be paved with Portland cement concrete (or, equivalent smooth impervious surface), with a 2% to 4% slope to prevent ponding, and must be separated from the rest of the site by a grade break that prevents runon of stormwater to the extent practicable. The fuel dispensing area is defined as extending 6.5 feet from the corner of each fuel dispenser or the length at which the hose and nozzle assembly may be operated plus 1 foot, whichever is less. The paving around the fuel dispensing area may exceed the minimum dimensions of the "fuel dispensing area" stated above. The fuel dispensing area must be covered, and the cover’s minimum dimensions must be equal to or greater than the area within the grade break or the fuel dispensing area, as defined above. The cover must not drain onto the fuel dispensing area. If necessary install and maintain an oil control device in the appropriate catch basin(s) to treat runoff from the fueling area. Outdoor Waste Receptacle Area Grade and pave the outdoor waste receptacle area to prevent runon of stormwater to the extent practicable. Air/Water Supply Area Grade and pave the air/water supply area to prevent runon of stormwater to the extent practicable. SC-20 Vehicle and Equipment Fueling 6 of 6 California Stormwater BMP Handbook January 2003 Municipal www.cabmphandbooks.com Designated Fueling Area If your facility has large numbers of mobile equipment working throughout the site and you currently fuel them with a mobile fuel truck, consider establishing a designated fueling area. With the exception of tracked equipment such as bulldozers and perhaps small forklifts, most vehicles should be able to travel to a designated area with little lost time. Place temporary “caps” over nearby catch basins or manhole covers so that if a spill occurs it is prevented from entering the storm drain. Examples The Spill Prevention Control and Countermeasure (SPCC) Plan, which is required by law for some facilities, is an effective program to reduce the number of accidental spills and minimize contamination of stormwater runoff. The City of Palo Alto has an effective program for commercial vehicle service facilities. Many of the program’s elements, including specific BMP guidance and lists of equipment suppliers, are also applicable to industrial facilities.

Use of the procedures outlined below can prevent or reduce the discharge of pollutants to stormwater during vehicle and equipment cleaning. Approach Reduce potential for pollutant discharge through source control pollution prevention and BMP implementation. Successful implementation depends on effective training of employees on applicable BMPs and general pollution prevention strategies and objectives Pollution Prevention If possible, use properly maintained off-site commercial washing and steam cleaning businesses whenever possible. These businesses are better equipped to handle and properly dispose of the wash waters. Good housekeeping practices can minimize the risk of contamination from wash water discharges. Objectives Cover Contain Educate Reduce/Minimize Product Substitution Targeted Constituents Sediment Nutrients Trash Metals Bacteria Oil and Grease Organics Oxygen Demanding Photo Credit: Geoff Brosseau SC-21 Vehicle and Equipment Cleaning 2 of 4 California Stormwater BMP Handbook January 2003 Municipal www.cabmphandbooks.com Suggested Protocols General Use biodegradable, phosphate-free detergents for washing vehicles as appropriate. Mark the area clearly as a wash area. Post signs stating that only washing is allowed in wash area and that discharges to the storm drain are prohibited. Provide a trash container in wash area. Map on-site storm drain locations to avoid discharges to the storm drain system. Emphasize the connection between the storm drain system and runoff and help reinforce that car washing activities can have an affect on local water quality. This can be accomplished through storm drain stenciling programs. Vehicle and Equipment Cleaning Design wash areas to properly collect and dispose of wash water when engine cleaning is conducted and when chemical additives, solvents, or degreasers are used. This may include installation of sumps or drain lines to collect wash water or construction of a berm around the designated area and grading of the area to collect wash water as well as prevent stormwater run-on. Consider washing vehicles and equipment inside the building if washing/cleaning must occur on-site. This will help to control the targeted constituents by directing them to the sanitary sewer. If washing must occur on-site and outdoor: - Use designated paved wash areas. Designated wash areas must be well marked with signs indicating where and how washing must be done. This area must be covered or bermed to collect the wash water and graded to direct the wash water to a treatment or disposal facility. - Oil changes and other engine maintenance cannot be conducted in the designated washing area. Perform these activities in a place designated for such activities. - Cover the wash area when not in use to prevent contact with rain water. Use hoses with nozzles that automatically turn off when left unattended. Perform pressure cleaning and steam cleaning off-site to avoid generating runoff with high pollutant concentrations. If done on-site, no pressure cleaning and steam cleaning should be done in areas designated as wellhead protection areas for public water supply. Disposal Consider filtering and recycling wash water. Vehicle and Equipment Cleaning SC-21 January 2003 California Stormwater BMP Handbook 3 of 4 Municipal www.cabmphandbooks.com Discharge equipment wash water to the sanitary sewer, a holding tank, or a process treatment system, regardless of the washing method used. Discharge vehicle wash water to (1) the sanitary sewer, a holding tank, or process treatment system or (2) an enclosed recycling system. Discharge wash water to sanitary sewer only after contacting the local sewer authority to find out if pretreatment is required. Training Train employees on proper cleaning and wash water disposal procedures and conduct “refresher” courses on a regular basis. Train staff on proper maintenance measures for the wash area. Train employees and contractors on proper spill containment and cleanup. The employee should have the tools and knowledge to immediately begin cleaning up a spill if one should occur. Spill Response and Prevention Refer to SC-11, Spill Prevention, Control and Cleanup. Keep your Spill Prevention Control and Counter Measure (SPCC) Plan up-to-date, and implement accordingly. Have spill cleanup materials readily available and in a known location. Clean up spills immediately and use dry methods if possible. Properly dispose of spill cleanup material. Other Considerations (Limitations and Regulations) Some municipalities may require pretreatment and monitoring of wash water discharges to the sanitary sewer. Steam cleaning can generate significant pollutant concentrations requiring that careful consideration be given to the environmental impacts and compliance issues related to steam cleaning. Most car washing best management practices are inexpensive, and rely more on good housekeeping practices (where vehicles are washed, planning for the collection of wash water) than on expensive technology. However, the construction of a specialized area for vehicle washing can be expensive for municipal facilities. Also, for facilities that cannot recycle their wash water the cost of pre-treating wash water through either structural practices or planning for collection and hauling of contaminated water to sewage treatment plants can represent a cost limitation. Requirements Costs Capital costs vary depending on measures implemented SC-21 Vehicle and Equipment Cleaning 4 of 4 California Stormwater BMP Handbook January 2003 Municipal www.cabmphandbooks.com - Low cost ($500-1,000) for berm construction, - Medium cost ($5,000-20,000) for plumbing modifications (including re-routing discharge to sanitary sewer and installing simple sump). - High cost ($30,000-150,000) for on-site treatment and recycling. O&M costs increase with increasing capital investment. Maintenance Berm repair and patching. Sweep washing areas frequently to remove solid debris. Inspect and maintain sumps, oil/water separators, and on-site treatment/recycling units. Supplemental Information Design Considerations Designated Cleaning Areas Washing operations outside should be conducted in a designated wash area having the following characteristics: - Paved with Portland cement concrete, - Covered and bermed to prevent contact with stormwater and contain wash water, - Sloped for wash water collection, - Equipped with an oil/water separator, if necessary. Examples The City of Palo Alto has an effective program for commercial vehicle service facilities. Many of the program’s elements, including specific BMP guidance and lists of equipment suppliers, are applicable to industrial vehicle service facilities. The U.S. Postal Service in West Sacramento has a new vehicle wash system that collects, filters, and recycles the wash water.

Additionally, rainfall may wash pollutants from machinery used to unload or move materials. Loading and unloading of material may include package products, barrels, and bulk products. Implementation of the following protocols will prevent or reduce the discharge of pollutants to stormwater from outdoor loading/unloading of materials. Approach Pollution Prevention Keep accurate maintenance logs to evaluate materials removed and improvements made. Park tank trucks or delivery vehicles in designated areas so that spills or leaks can be contained. Limit exposure of materials with the potential to contaminate stormwater. Prevent stormwater runon. Regularly check equipment for leaks. Objectives Cover Contain Educate Reduce/Minimize Product Substitution Targeted Constituents Sediment Nutrients Trash Metals Bacteria Oil and Grease Organics Oxygen Demanding SC-30 Outdoor Loading/Unloading 2 of 4 California Stormwater BMP Handbook January 2003 Municipal www.cabmphandbooks.com Suggested Protocols Loading and Unloading – General Guidelines Develop an operations plan that describes procedures for loading and/or unloading. Do not conduct loading and unloading during wet weather, whenever possible. Cover designated loading/unloading areas to reduce exposure of materials to rain. A seal or door skirt between delivery vehicles and building can reduce or prevent exposure to rain. Design loading/unloading area to prevent stormwater runon which would include grading or berming the area, and positioning roof downspouts so they direct stormwater away from the loading/unloading areas. If feasible, load and unload all materials and equipment in covered areas such as building overhangs at loading docks. Load/unload only at designated loading areas. Use drip pans underneath hose and pipe connections and other leak-prone spots during liquid transfer operations, and when making and breaking connections. Several drip pans should be stored in a covered location near the liquid transfer area so that they are always available, yet protected from precipitation when not in use. Drip pans can be made specifically for railroad tracks. Drip pans must be cleaned periodically, and drip collected materials must be disposed of properly. Pave loading areas with concrete instead of asphalt. Avoid placing storm drains in the area. Grade and/or berm he loading/ unloading area to a drain that is connected to a dead-end sump. Inspection Check loading and unloading equipment regularly for leaks, including valves, pumps, flanges and connections. Look for dust or fumes during loading or unloading operations. Training Train employees (e.g. fork lift operators) and contractors on proper spill containment and cleanup. Employees trained in spill containment and cleanup should be present during the loading/unloading. Train employees in proper handling techniques during liquid transfers to avoid spills. Outdoor Loading/Unloading SC-30 January 2003 California Stormwater BMP Handbook 3 of 4 Municipal www.cabmphandbooks.com Make sure forklift operators are properly trained on loading and unloading procedures. Spill Response and Prevention Refer to SC-11, Spill Prevention, Control & Cleanup Keep your spill prevention Control and countermeasure (SPCC) Plan up-to-date, and implement accordingly. Have spill cleanup materials readily available and in a known location. Cleanup spills immediately and use dry methods if possible. Properly dispose of spill cleanup material. Other Considerations Space, material characteristics and/or time limitations may preclude all transfers from being performed indoors or under cover. Requirements Costs Should be low except when covering a large loading/unloading area. Maintenance Conduct regular inspections and make repairs as necessary. The frequency of repairs will depend on the age of the facility. Check loading and unloading equipment regularly for leaks. Regular broom dry-sweeping of area. Conduct major clean-out of loading and unloading area and sump prior to October 1 of each year. Supplemental Information Further Detail of the BMP Special Circumstances for Indoor Loading/Unloading of Materials As appropriate loading or unloading of liquids should occur indoors so that any spills that are not completely retained can be discharged to the sanitary sewer, treatment plant, or treated in a manner consistent with local sewer authorities and permit requirements. For loading and unloading tank trucks to above and below ground storage tanks, the following procedures should be used: - The area where the transfer takes place should be paved. If the liquid is reactive with the asphalt, Portland cement should be used to pave the area. - Transfer area should be designed to prevent runon of stormwater from adjacent areas. Sloping the pad and using a curb, like a speed bump, around the uphill side of the transfer area should reduce run-on. SC-30 Outdoor Loading/Unloading 4 of 4 California Stormwater BMP Handbook January 2003 Municipal www.cabmphandbooks.com - Transfer area should be designed to prevent runoff of spilled liquids from the area. Sloping the area to a drain should prevent runoff. The drain should be connected to a dead-end sump or to the sanitary sewer (if allowed). A positive control valve should be installed on the drain. For transfer from rail cars to storage tanks that must occur outside, use the following procedures: - Drip pans should be placed at locations where spillage may occur, such as hose connections, hose reels, and filler nozzles, Use drip pans when making and breaking connections. - Drip pan systems should be installed between the rails to collect spillage from tank cars.

Utilizing the following protocols will prevent or reduce the discharge of pollutants to stormwater from building and grounds maintenance activities by washing and cleaning up with as little water as possible, following good landscape management practices, preventing and cleaning up spills immediately, keeping debris from entering the storm drains, and maintaining the stormwater collection system. Approach Pollution Prevention Switch to non-toxic chemicals for maintenance when possible. Choose cleaning agents that can be recycled. Encourage proper lawn management and landscaping, including use of native vegetation. Encourage use of Integrated Pest Management techniques for pest control. Encourage proper onsite recycling of yard trimmings. Recycle residual paints, solvents, lumber, and other material as much as possible. Objectives Cover Contain Educate Reduce/Minimize Product Substitution Targeted Constituents Sediment Nutrients Trash Metals Bacteria Oil and Grease Organics Oxygen Demanding SC-41 Building & Grounds Maintenance 2 of 5 California Stormwater BMP Handbook January 2003 Municipal www.cabmphandbooks.com Suggested Protocols Pressure Washing of Buildings, Rooftops, and Other Large Objects In situations where soaps or detergents are used and the surrounding area is paved, pressure washers must use a waste water collection device that enables collection of wash water and associated solids. A sump pump, wet vacuum or similarly effective device must be used to collect the runoff and loose materials. The collected runoff and solids must be disposed of properly. If soaps or detergents are not used, and the surrounding area is paved, wash water runoff does not have to be collected but must be screened. Pressure washers must use filter fabric or some other type of screen on the ground and/or in he catch basin to trap the particles in wash water runoff. If you are pressure washing on a grassed area (with or without soap), runoff must be dispersed as sheet flow as much as possible, rather than as a concentrated stream. The wash runoff must remain on the grass and not drain to pavement. Ensure that this practice does not kill grass. Landscaping Activities Do not apply any chemicals (insecticide, herbicide, or fertilizer) directly to surface waters, unless the application is approved and permitted by the state. Dispose of grass clippings, leaves, sticks, or other collected vegetation as garbage, or by composting. Do not dispose of collected vegetation into waterways or storm drainage systems. Use mulch or other erosion control measures on exposed soils. Check irrigation schedules so pesticides will not be washed away and to minimize non- stormwater discharge. Building Repair, Remodeling, and Construction Do not dump any toxic substance or liquid waste on the pavement, the ground, or toward a storm drain. Use ground or drop cloths underneath outdoor painting, scraping, and sandblasting work, and properly dispose of collected material daily. Use a ground cloth or oversized tub for activities such as paint mixing and tool cleaning. Clean paint brushes and tools covered with water-based paints in sinks connected to sanitary sewers or in portable containers that can be dumped into a sanitary sewer drain. Brushes and tools covered with non-water-based paints, finishes, or other materials must be cleaned in a manner that enables collection of used solvents (e.g., paint thinner, turpentine, etc.) for recycling or proper disposal. Building & Grounds Maintenance SC-41 January 2003 California Stormwater BMP Handbook 3 of 5 Municipal www.cabmphandbooks.com Use a storm drain cover, filter fabric, or similarly effective runoff control mechanism if dust, grit, wash water, or other pollutants may escape the work area and enter a catch basin. The containment device(s) must be in place at the beginning of the work day, and accumulated dirty runoff and solids must be collected and disposed of before removing the containment device(s) at the end of the work day. If you need to de-water an excavation site, you may need to filter the water before discharging to a catch basin or off-site. In which case you should direct the water through hay bales and filter fabric or use other sediment filters or traps. Store toxic material under cover with secondary containment during precipitation events and when not in use. A cover would include tarps or other temporary cover material. Mowing, Trimming, and Planting Dispose of leaves, sticks, or other collected vegetation as garbage, by composting or at a permitted landfill. Do not dispose of collected vegetation into waterways or storm drainage systems. Use mulch or other erosion control measures when soils are exposed. Place temporarily stockpiled material away from watercourses and drain inlets, and berm or cover stockpiles to prevent material releases to the storm drain system. Consider an alternative approach when bailing out muddy water; do not put it in the storm drain, pour over landscaped areas. Use hand or mechanical weeding where practical. Fertilizer and Pesticide Management Follow all federal, state, and local laws and regulations governing the use, storage, and disposal of fertilizers and pesticides and training of applicators and pest control advisors. Follow manufacturers’ recommendations and label directions. Pesticides must never be applied if precipitation is occuring or predicted. Do not apply insecticides within 100 feet of surface waters such as lakes, ponds, wetlands, and streams. Use less toxic pesticides that will do the job, whenever possible. Avoid use of copper-based pesticides if possible. Do not use pesticides if rain is expected. Do not mix or prepare pesticides for application near storm drains. Use the minimum amount needed for the job. Calibrate fertilizer distributors to avoid excessive application. Employ techniques to minimize off-target application (e.g. spray drift) of pesticides, including consideration of alternative application techniques. SC-41 Building & Grounds Maintenance 4 of 5 California Stormwater BMP Handbook January 2003 Municipal www.cabmphandbooks.com Apply pesticides only when wind speeds are low. Work fertilizers into the soil rather than dumping or broadcasting them onto the surface. Irrigate slowly to prevent runoff and then only as much as is needed. Clean pavement and sidewalk if fertilizer is spilled on these surfaces before applying irrigation water. Dispose of empty pesticide containers according to the instructions on the container label. Use up the pesticides. Rinse containers, and use rinse water as product. Dispose of unused pesticide as hazardous waste. Implement storage requirements for pesticide products with guidance from the local fire department and County Agricultural Commissioner. Provide secondary containment for pesticides. Inspection Inspect irrigation system periodically to ensure that the right amount of water is being applied and that excessive runoff is not occurring. Minimize excess watering, and repair leaks in the irrigation system as soon as they are observed. Training Educate and train employees on use of pesticides and in pesticide application techniques to prevent pollution. Train employees and contractors in proper techniques for spill containment and cleanup. Be sure the frequency of training takes into account the complexity of the operations and the nature of the staff. Spill Response and Prevention Refer to SC-11, Spill Prevention, Control & Cleanup Keep your Spill Prevention Control and countermeasure (SPCC) plan up-to-date, and implement accordingly. Have spill cleanup materials readily available and in a known location. Cleanup spills immediately and use dry methods if possible. Properly dispose of spill cleanup material. Other Considerations Alternative pest/weed controls may not be available, suitable, or effective in many cases. Building & Grounds Maintenance SC-41 January 2003 California Stormwater BMP Handbook 5 of 5 Municipal www.cabmphandbooks.com Requirements Costs Overall costs should be low in comparison to other BMPs. Maintenance Sweep paved areas regularly to collect loose particles, and wipe up spills with rags and other absorbent material immediately, do not hose down the area to a storm drain. Supplemental Information Further Detail of the BMP Fire Sprinkler Line Flushing Building fire sprinkler line flushing may be a source of non-stormwater runoff pollution. The water entering the system is usually potable water though in some areas it may be non-potable reclaimed wastewater. There are subsequent factors that may drastically reduce the quality of the water in such systems. Black iron pipe is usually used since it is cheaper than potable piping but it is subject to rusting and results in lower quality water. Initially the black iron pipe has an oil coating to protect it from rusting between manufacture and installation; this will contaminate the water from the first flush but not from subsequent flushes. Nitrates, poly- phosphates and other corrosion inhibitors, as well as fire suppressants and antifreeze may be added to the sprinkler water system. Water generally remains in the sprinkler system a long time, typically a year, between flushes and may accumulate iron, manganese, lead, copper, nickel and zinc. The water generally becomes anoxic and contains living and dead bacteria and breakdown products from chlorination. This may result in a significant BOD problem and the water often smells. Consequently dispose fire sprinkler line flush water into the sanitary sewer. Do not allow discharge to storm drain or infiltration due to potential high levels of pollutants in fire sprinkler line water.

The following protocols are intended to prevent or reduce the discharge of pollutants from parking/storage areas and include using good housekeeping practices, following appropriate cleaning BMPs, and training employees. Approach Pollution Prevention Encourage alternative designs and maintenance strategies for impervious parking lots. (See New Development and Redevelopment BMP Handbook). Keep accurate maintenance logs to evaluate BMP implementation. Suggested Protocols General Keep the parking and storage areas clean and orderly. Remove debris in a timely fashion. Allow sheet runoff to flow into biofilters (vegetated strip and swale) and/or infiltration devices. Utilize sand filters or oleophilic collectors for oily waste in low concentrations. Objectives Cover Contain Educate Reduce/Minimize Product Substitution Targeted Constituents Sediment Nutrients Trash Metals Bacteria Oil and Grease Organics Oxygen Demanding SC-43 Parking/Storage Area Maintenance 2 of 4 California Stormwater BMP Handbook January 2003 Municipal www.cabmphandbooks.com Arrange rooftop drains to prevent drainage directly onto paved surfaces. Design lot to include semi-permeable hardscape. Controlling Litter Post “No Littering” signs and enforce anti-litter laws. Provide an adequate number of litter receptacles. Clean out and cover litter receptacles frequently to prevent spillage. Provide trash receptacles in parking lots to discourage litter. Routinely sweep, shovel and dispose of litter in the trash. Surface cleaning Use dry cleaning methods (e.g. sweeping or vacuuming) to prevent the discharge of pollutants into the stormwater conveyance system. Establish frequency of public parking lot sweeping based on usage and field observations of waste accumulation. Sweep all parking lots at least once before the onset of the wet season. If water is used follow the procedures below: - Block the storm drain or contain runoff. - Wash water should be collected and pumped to the sanitary sewer or discharged to a pervious surface, do not allow wash water to enter storm drains. - Dispose of parking lot sweeping debris and dirt at a landfill. When cleaning heavy oily deposits: - Use absorbent materials on oily spots prior to sweeping or washing. - Dispose of used absorbents appropriately. Surface Repair Pre-heat, transfer or load hot bituminous material away from storm drain inlets. Apply concrete, asphalt, and seal coat during dry weather to prevent contamination form contacting stormwater runoff. Cover and seal nearby storm drain inlets (with waterproof material or mesh) and manholes before applying seal coat, slurry seal, etc., where applicable. Leave covers in place until job is complete and until all water from emulsified oil sealants has drained or evaporated. Clean any debris from these covered manholes and drains for proper disposal. Parking/Storage Area Maintenance SC-43 January 2003 California Stormwater BMP Handbook 3 of 4 Municipal www.cabmphandbooks.com Use only as much water as necessary for dust control, to avoid runoff. Catch drips from paving equipment that is not in use with pans or absorbent material placed under the machines. Dispose of collected material and absorbents properly. Inspection Have designated personnel conduct inspections of the parking facilities and stormwater conveyance systems associated with them on a regular basis. Inspect cleaning equipment/sweepers for leaks on a regular basis. Training Provide regular training to field employees and/or contractors regarding cleaning of paved areas and proper operation of equipment. Train employees and contractors in proper techniques for spill containment and cleanup. Spill Response and Prevention Refer to SC-11, Spill Prevention, Control & Cleanup. Keep your Spill Prevention Control and countermeasure (SPCC) plan up-to-date, nad implement accordingly. Have spill cleanup materials readily available and in a known location. Cleanup spills immediately and use dry methods if possible. Properly dispose of spill cleanup material. Other Considerations Limitations related to sweeping activities at large parking facilities may include high equipment costs, the need for sweeper operator training, and the inability of current sweeper technology to remove oil and grease. Requirements Costs Cleaning/sweeping costs can be quite large, construction and maintenance of stormwater structural controls can be quite expensive as well. Maintenance Sweep parking lot to minimize cleaning with water. Clean out oil/water/sand separators regularly, especially after heavy storms. Clean parking facilities on a regular basis to prevent accumulated wastes and pollutants from being discharged into conveyance systems during rainy conditions. SC-43 Parking/Storage Area Maintenance 4 of 4 California Stormwater BMP Handbook January 2003 Municipal www.cabmphandbooks.com Supplemental Information Further Detail of the BMP Surface Repair Apply concrete, asphalt, and seal coat during dry weather to prevent contamination form contacting stormwater runoff.
