structural control such as an oil/water separator or sand filter. No other <br /> area shall drain into the trash enclosure; a ridge or a berm shall be <br /> constructed to prevent such drainage if found necessary by the City <br /> Engineer/Chief Building Official. A sign shall be posted prohibiting the <br /> dumping of hazardous materials into the sanitary sewer. The project <br /> developer shall notify the Dublin San Ramon Services District of the <br /> sanitary sewer connection and provide written verification of such <br /> notification to the City Engineer/Chief Building Official prior to the <br /> installation of the connection. <br /> g. All paved outdoor storage areas shall be designed to minimize pollutant <br /> runoff. Bulk materials stored outdoors that may contribute to the pollution <br /> of stormwater runoff must be covered as deemed appropriate by the City <br /> Engineer/Chief Building. <br /> h. All metal roofs, gutters, and downspouts shall be finished with rust- <br /> inhibitive finish/paint as determined by the Chief Building Official. <br /> All projects using architectural copper roofing, gutters, downspouts, etc., <br /> shall utilize the following Best Management Practices for the use and <br /> maintenance: <br /> a. During installation, copper material shall be pre-patinated at <br /> the factory, if available. If patination is done on-site, collect <br /> the rinse water in a tank and haul off-site for disposal. With <br /> prior authorization from Dublin San Ramon Services District <br /> (DSRSD), the rinse water may be collected in a tank and <br /> discharged to the sanitary sewer. Consider coating the <br /> copper materials with a clear coating that prevents further <br /> corrosion and stormwater pollution. The clear coating, if <br /> utilized, shall be reapplied (as recommended by the coating <br /> manufacturer) to maintain its efficacy. <br /> b. During maintenance (e.g., washing or re-patination), the <br /> following applies: <br /> Minimize washing of architectural copper as it <br /> damages the patina and any protective coating. <br /> ii. Block storm drain inlets as needed to prevent runoff <br /> from entering storm drains. <br /> iii. Collect the wash or rinse water in a tank and dispose <br /> off-site or (with prior authorization from DSRSD), <br /> discharge the wash or rinse water to the sanitary <br /> sewer. <br /> PUD-87, Auf der Maur/ Rickenbach /Vintage City Council <br /> Page 35 of 39 <br />
