4) identify areas where run-off is (or could be rendered ) <br /> acceptable for direct discharge as non-contaminated run-off <br /> and negotiate with regulatory agencies for appropriate <br /> j permits to segregate, retain , and ultimately discharge this <br /> i water to surface waters ; <br /> 5 ) identify processes and operations contributory to areas <br /> recording maximum contaminant loads ; <br /> 6 ) investigate potential improvements in housekeeping <br /> procedures (e.g. routine yard sweeping and dry clean -up ) <br /> and/or process /structural changes (e.g. spray washing of <br /> preserved wood prior to yard storage , roofing of storage <br /> areas ) which will effect significant reductions in <br /> contaminantaddition to precipitate run -off within the <br /> identified contaminated run-off areas. <br /> 7 ) implement recommended housekeeping improvements and <br /> process/structural changes identified to be cost effective <br /> in (6 ). <br /> Marley anticipates that the above program will result in the <br /> l following two segregated precipitation run -off flows : (a ) a <br /> high volume, non-contaminated flow targeted for direct discharge <br /> to surface waters of the area ; and (b) a relatively low volume, <br /> high contamination flow which can be used as process make- up <br /> water and/or will require alternative treatment/disposal methods. <br /> 1 <br /> The second area requiring attention is that of ultimate <br /> disposal of excess precipitation at the site. The program <br /> outlined above will provide information required to minimize run- <br /> ( 9 <br />
