Transfer/Processing Report <br />Tracy Material Recovery and Transfer Facility <br />30703 S. MacArthur Drive, Tracy, California 95377 <br />Employee restroom facilities are available in the MRF/TS building, at the <br />maintenance/office building. The operator will maintain all sanitary and hand - <br />washing facilities, which may be required by applicable state or local requirements, <br />in a reasonably clean and adequately supplied condition. <br />J. Process Water <br />18221.6(i) anticipated volume of quench or process water, and the planned <br />method of treatment, and disposal of any wastewater <br />The anticipated volume of process water from the Material Recovery and Transfer <br />Facility is the amount of liquids that may make contact with the MSW, <br />compostable materials, or C&D debris during storage, processing, or transfer. The <br />amount of free liquids that may be generated from this material is minimized <br />through the use of best management practices; all process water is retained <br />onsite. <br />Dust mitigation does involve spraying of water from hand held hoses onto <br />excessively dust -producing materials during transfer operations. The amount of <br />liquids added for dust suppression is minimal and is not enough to generate any <br />ponding or standing water. <br />Abft <br />The facility has been exempted from coverage under the NPDES General <br />qV <br />Industrial Permit by the State Water Resources Control Board because all <br />operations occur below existing grade and stormwater is retained onsite in a lined <br />basin. <br />v <br />Surface water runoff, including all process water, will be directed to a onsite <br />retention basin by use of grading design, drain pipes, and drainage ditches, where <br />it will be properly treated, if necessary, to eliminate potential environmental <br />impacts. Water will be pumped from the retention basin for facility use in <br />operations, including fire and dust control. <br />The retention basin has been designed to retain all surface water runoff resulting <br />from a 100 -year, 24-hour storm event. Site personnel will regularly inspect and <br />maintain the storm drains, drainage ditches and basin. <br />41 <br />
