Worksheet B <br />C.3 – Source Controls <br />Select appropriate source controls and identify the detail/plan sheet where these elements are shown. <br />Yes Detail/Plan <br />Sheet No. <br />8 Any connection to the sanitary sewer system is subject to sanitary district approval. <br />9 Businesses that may have outdoor process activities/equipment include machine shops, auto repair, industries with pretreatment facilities. <br />10 See the Flowstobay website: https://flowstobay.org/wp-content/uploads/2020/04/ArchitecturalcopperBMPs.pdf <br />■ Fueling areas shall have impermeable surface that is a) minimally graded to prevent ponding and b) <br />separated from the rest of the site by a grade break. <br />■ Canopy shall extend at least 10 ft. in each direction from each pump and drain away from fueling area. <br />■ Cover and/or grade to minimize run-on to and runoff from the loading area. <br />■ Position downspouts to direct stormwater away from the loading area. <br />■ Drain water from loading dock areas to the sanitary sewer.8 <br />■ Install door skirts between the trailers and the building. <br />Design for discharge of fire sprinkler test water to landscape or sanitary sewer.8 <br />■ Drain condensate of air conditioning units to landscaping. Large air conditioning units may connect to <br />the sanitary sewer.8 <br />■ Roof drains from equipment drain to landscaped area where practicable. <br />■ Drain boiler drain lines, roof top equipment, all wash water to sanitary sewer.8 <br />Architectural Copper <br />Rinse Water ■ Drain rinse water to landscaping, discharge to sanitary sewer8, or collect and dispose properly offsite. <br />See flyer “Requirements for Architectural Copper.”10 <br />Miscellaneous Drain <br />or Wash Water <br />Fire Sprinklers <br />Outdoor Equipment/ <br />Materials Storage <br />Provide sink or other area for equipment cleaning, which is: <br />■ Connected to a grease interceptor prior to sanitary sewer discharge.8 <br />■ Large enough for the largest mat or piece of equipment to be cleaned. <br />■ Indoors or in an outdoor roofed area designed to prevent stormwater run-on and run-off, and signed to <br />require equipment washing in this area. <br />■ Provide a roofed and enclosed area for dumpsters, recycling containers, etc., designed to prevent <br />stormwater run-on and runoff. <br />■ Connect any drains in or beneath dumpsters, compactors, and tallow bin areas serving food service <br />facilities to the sanitary sewer.8 <br />■ For more information, see the New Development Projects Litter Reduction Fact Sheet at: <br />https://www.flowstobay.org/wp-content/uploads/2021/06/New-Dev-Litter-Reduction-Fact-Sheet- <br />060421.pdf <br />Perform process activities either indoors or in roofed outdoor area, designed to prevent stormwater run- <br />on and runoff, and to drain to the sanitary sewer.8 <br />■ Cover the area or design to avoid pollutant contact with stormwater runoff. <br />■ Locate area only on paved and contained areas. <br />■ Roof storage areas that will contain non-hazardous liquids, drain to sanitary sewer8, and contain by <br />berms or similar. <br />Outdoor Process <br />Activities9 <br />Refuse Areas <br />■ Designate repair/maintenance area indoors, or an outdoors area designed to prevent stormwater run- <br />on and runoff and provide secondary containment. Do not install drains in the secondary containment <br />areas. <br />■ No floor drains unless pretreated prior to discharge to the sanitary sewer.8 <br />■ Connect containers or sinks used for parts cleaning to the sanitary sewer.8 <br />Vehicle/ Equipment <br />Repair and <br />Maintenance <br />Fuel Dispensing <br />Areas <br />Loading Docks <br />Vehicle/ Equipment <br />Cleaning <br />■ Roofed, pave and berm wash area to prevent stormwater run-on and runoff, plumb to the sanitary <br />sewer8, and sign as a designated wash area. <br />■ Commercial car wash facilities shall discharge to the sanitary sewer.8 <br />Features that <br />require <br />source control <br />Source Control Measures <br />(Refer to Local Source Control List for detailed requirements) <br />Storm Drain <br />Floor Drains <br />Parking garage <br />Mark on-site inlets with the words “No Dumping! Flows to Bay” or equivalent. <br />Plumb interior floor drains to sanitary sewer [or prohibit]. <br />Plumb interior parking garage floor drains to sanitary sewer.8 <br />Provide connection to the sanitary sewer to facilitate draining.8 <br />■ Retain existing vegetation as practicable. <br />■ Follow ReScape (www.rescapeca.org) principles. Select diverse species appropriate to the site. <br />Include plants that are pest- and/or disease-resistant, drought-tolerant, and/or attract beneficial insects. <br />■ Minimize use of pesticides and quick-release fertilizers. <br />■ Use efficient irrigation system; design to minimize runoff. <br />Landscaping <br />Pool/Spa/Fountain <br />Food Service <br />Equipment (non- <br />residential) <br />7.A. - Page 60 of 121 <br />66
