Ordinance No. 2200 Page 19 of 26 79. STORMWATER POLLUTION CONTROL PLAN: The project will disturb less than 1 acre of land during the construction phase. The applicant shall include a Stormwater Pollution Control Plan (SWPCP) on the improvement plans with the first improvement plans review submittal to the City. The SWPCP shall include Stormwater Best Management Practices (BMPs) to be used at the project site for review and approval by the Director of Engineering/City Engineer. The applicant, general contractor and all subcontractors and suppliers of materials and equipment shall implement these BMPs. All construction projects shall be conducted in a manner which prevents the release of hazardous materials, hazardous waste, polluted water, and sediments to the storm drain system. 80. LANDSCAPE DESIGN: Landscape shall be designed to minimize runoff, promote surface filtration, and minimize the use of fertilizers and pesticides that contribute to stormwater pollution. Examples include: (a) design structures to prohibit the entry of pests, minimizing the need for pesticides; (b) install appropriate plants for the location in accordance with appropriate climate zones; and (c) install and maintain landscaping to treat stormwater runoff. 81. TRASH ENCLOSURES: Trash areas including containers for trash, recycling, and organic waste/composting shall be enclosed and roofed per the city's trash enclosure design guidelines available on the City's website and as required by the NPDES Permit No. CAS612008 and amendments, issued by the San Francisco Bay Regional Water Quality Control Board. The trash enclosure shall be constructed to prevent stormwater run-on and runoff and to contain litter and trash, so that it is not dispersed by the wind or runoff during waste removal. The area enclosed shall drain to the sanitary sewer system and an area drain shall be installed in the enclosure area, providing a structural control such as an oil/water separator or sand filter. No other area shall drain into the trash enclosure. A sign shall be posted prohibiting the dumping of hazardous materials into the sanitary sewer. 82. FULL TRASH CAPTURE DEVICES: The applicant shall install trash capture devices at each upstream connection point to the public storm drain system subject to the review and approval of the Director of Engineering/City Engineer. Stormwater treatment controls, proposed in compliance with Provision C.3 of NPDES Permit No. CAS612008, shall also prevent the discharge of trash to the downstream municipal separate storm sewer systems and receiving waters. Discharge points from these treatment control facilities, including overflows, shall be appropriately screened (5 mm mesh screen) or otherwise configured to meet the full trash capture screening specification for storm flows up to the full trash capture 1-year, 1-hour storm hydraulic specification, in compliance with the NPDES Permit No. CAS612008. The applicant shall submit a Stormwater Management Plan as part of the improvement plans prepared by a California licensed civil engineer, which include but is not limited to the type, location, and sizing calculations of the treatment controls that will be installed. Full trash capture devices shall be a part of the "Stormwater Treatment Measures and Maintenance Agreement." 83. RESTAURANTS AND FOOD ESTABLISHMENTS: The applicant shall provide a contained area for cleaning mats, containers and equipment. The wash area shall be covered or designed to prevent runoff onto or from the area. The area shall be connected to the sanitary sewer system, subject to approval by the Dublin San Ramon Services District, or the cleaning mats, containers and equipment shall be collected in a containment area and removed regularly by a disposal and recycling service. If connected to the sanitary sewer, a grease abatement device (grease trap or interceptor) shall be installed, and a sign shall be posted prohibiting the dumping of hazardous materials.
