prevents further corrosion and stormwater pollution. The clear <br /> coating, if utilized, shall be reapplied (as recommended by the <br /> coating manufacturer) to 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 <br /> flow shall drain to a landscaped area or to an unpaved area wherever <br /> practicable as determined by the City Engineer/Chief Building Official. <br /> k. There shall be no direct roof leaders connected to the street gutter/parking <br /> lot or storm drain system, unless otherwise approved by the City engineer. <br /> B. Construction Requirements <br /> The project shall comply with the "Construction General Permit" requirements <br /> of the NPDES Permit for construction activities (including other land <br /> disturbing activities) that disturb one acre or more (including smaller sites that <br /> are part of a larger common plan of development). <br /> Information related to the Construction General Permit is on line at: <br /> • http://www.waterboards.ca.qov/water issues/proqrams/stormwater/construction <br /> .shtml <br /> • http://www.waterboards.ca.qov/water issues/proqrams/stormwater/docs/finalco <br /> nstpermit.pdf <br /> 1. The Construction General Permit's requirements include, but are not limited <br /> to, the following: <br /> a. The project developer shall obtain a construction general permit (N01) <br /> from the Regional Water Quality Control Board to discharge stormwater, <br /> and to develop and implement stormwater pollution prevention plans. <br /> b. The project developer shall submit a Stormwater Pollution Prevention Plan <br /> (SWPPP) to the City Engineer/Chief Building Official for review and <br /> approval prior to the issuance of a grading or building permit, whichever is <br /> sooner. A copy of the approved SWPPP, including all approved <br /> amendments, shall be available at the project site for City review until all <br /> engineering and building work is complete and City permits have been <br /> finaled. A site specific SWPPP must be combined with proper and timely <br /> installation of the BMPs, thorough and frequent inspections, maintenance, <br /> and documentations. SWPPP for projects shall be kept up to date with <br /> 28 <br />
