During installation, copper material shall be pre-patinated at the <br /> factory. If patination is done on-site; collect the rinse water in a tank <br /> and haul off-site for disposal. With prior authorization from Dublin San <br /> Ramon Services District (DSRSD), you may collect the rinse water in a <br /> tank and discharge to the sanitary sewer. Optionally, consider coating <br /> the copper materials with a clear coating that prevents further <br /> corrosion and stormwater pollution. The clear coating, if utilized, shall <br /> be reapplied (as recommended by the coating manufacturer) to <br /> maintain its efficacy. <br /> b. During maintenance, the following applies during washing and <br /> patination: <br /> i. Minimize washing of architectural copper as it damages the <br /> patina and any protective coating. <br /> ii. Block all storm drain inlets downstream of the wash. <br /> iii. collect in a tank and dispose off-site, or discharge the wash <br /> water to the sanitary sewer (with prior authorization from <br /> DSRSD). <br /> c. During re-patination, collect the rinse water in a tank and dispose off- <br /> site or discharge to sewer(with prior authorization from DSRSD) . <br /> j. Roof drains shall drain away from the building foundation. Stormwater flow <br /> shall drain to a landscaped area or to an unpaved area wherever practicable <br /> as determined by the City Engineer/Chief Building Official. <br /> k.
