Project Description <br /> Tracy Material Recovery Facility and Transfer Station Expansion <br /> f 30703 S. MacArthur Drive, Tracy, California 95377 <br /> Utilities <br /> Utilities required for operation of the Tracy MRF & TS include water, electricity, sanitary <br /> sewer, and telephone service. Existing and proposed utilities are described below. <br /> Water Usage: <br /> All water required for facility operations, including potable water, is obtained from an on- <br /> site groundwater supply well. This on-site also supplies an on-site, 150,000 gallon storage <br /> tank to satisfy local fire protection requirements. Electrical fire pumps are installed to <br /> serve the fire main and fire hydrant system and building sprinkler systems. A diesel <br /> generator is provided on-site for emergency power. <br /> Sanitary Sewer: <br /> All sanitary sewer wastes are collected and disposed of in a subsurface leach field <br /> installed on-site. The design of this system is per San Joaquin County Public Health <br /> Services requirements. <br /> All water used in the washdown of the MRF/Transfer Building, contact water that may <br /> be generated from being brought in by solid waste trucks during discharging of solid <br /> waste, and the storm water that may end up in the loading bays, will be collected and be <br /> pumped to a storage tank for disposal off site, and will not be discharge into the septic <br /> system. <br /> The Tracy MRF & TS does not accept liquid wastes. <br /> Electricity: Electricity is provided by the local power company. <br /> Storm Drainage: <br /> The facility will operate under a Storm Water Pollution Prevention Plan filed with the <br /> California State Water Resources Control Board. The facility will operate on concrete or <br /> asphalt-concrete. <br /> Surface water runoff, including all process water, will be directed to a onsite retention <br /> basin by use of grading design, drain pipes, and drainage ditches, where it will be <br /> properly treated, if necessary, to eliminate potential environmental impacts. Water will <br /> be pumped from the retention basin for facility use in operations, including fire and dust <br /> control. <br /> The retention basin has been designed (see calculations in Appendix D) to retain all <br /> surface water runoff resulting from a 100-year, 24-hour storm event. Site personnel will <br /> regularly inspect and maintain the, storm drains, drainage ditches and basin. <br /> 16 <br /> 170.18.03 CUP Project Description 121807 <br />
