d) Trash areas, dumpsters and recycling containers shall be enclosed and roofed to prevent water run-on to the area and runoff from the area and to contain litter and trash, so that it is not dispersed by the wind or runoff during waste removal. These areas shall not drain to the storm drain system, but 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 ridge or a berm shall be constructed to prevent such drainage if found necessary by the City Engineer/Chief Building Official. A sign shall be posted prohibiting the dumping of hazardous materials into the sanitary sewer. The project developer shall notify the Dublin-San Ramon Services District (DSRSD) upon installation of the sanitary connection; a copy of this notification shall be provided to the Planning Department. e) All paved outdoor storage areas shall be designed to minimize pollutant runoff. Bulk materials stored outdoors that may contribute to the pollution of stormwater runoff must be covered as deemed appropriate by the City Engineer/Chief Building Official and as required by the State Water Board. f) All metal roofs, if used, shall be finished with rust-inhibitive paint. g) Roof drains shall discharge and drain away from the building foundation.
