Transfer/Processing Report <br /> Tracy Material Recovery& Transfer Facility <br /> 30703 S. MacArthur Drive, Tracy, California 95377 <br /> 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, compostable <br /> materials, or C&D debris during storage, processing, or transfer. The amount of free <br /> liquids that may be generated from this material is minimized through the use of best <br /> management practices; all process water is retained 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 /> Wastewater from the composting operations are managed in accordance with the <br /> Statewide General Waste Discharge Requirements for Composting Operations. The <br /> onsite wastewater and stormwater retention basins have been expanded in <br /> accordance with required capacities. <br /> The facility has been exempted from coverage under the NPDES General Industrial <br /> Permit by the State Water Resources Control Board because all operations occur <br /> below existing grade and stormwater is retained onsite in a lined basin. <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 impacts. <br /> Water will be pumped from the retention basin for facility use in operations, including <br /> fire and dust control. <br /> The retention basin has been designed, and recently reconstructed, to retain all <br /> surface water runoff resulting from a 100-year, 24-hour storm event. Site personnel <br /> will regularly inspect and maintain the storm drains, drainage ditches and basin. <br /> 42 <br />
