2.0 DESCRIPTION OF HAZARDOUS WASTE TANK SYSTEM <br /> 2.1 Facility Operations <br /> The Site is a self-service auto dismantling facility where customers purchase car parts which they <br /> remove themselves from a selection of salvage cars. Facility operations include draining fluids from <br /> new cars arriving on-Site(including gas, oil, and radiatorfluid); mounting cars on stands in the yard <br /> for customer access; removing radiators and core parts from salvaged cars; and loading core parts <br /> and tires onto separate trucks for off-Site recycling. Gasoline is drained from salvaged cars but is <br /> transferred out of building by steel piping and stored in double walled still tanks. Gasoline storage is <br /> not included as a part of this hazardous waste assessment. <br /> The Site encompasses approximately 26 acres. Of this, approximately 6.5 acres are used for such <br /> operations as car crushing, core and parts storage, and vehicle preparation; 17 acres are used for <br /> the customer salvage yard; and 2.5 acres are used for the customer parking lot. <br /> A Partial Site Plan is provided in Figure 2 and photographs of the Site are provided in Appendix A. <br /> 2.2 Tanks <br /> The eight tanks at the Site were numbered 01, 02, 03, 04, Al, A2, A3, and A4 for ease of <br /> reference in this report(refer to Figure 3). The hazardous waste tank system at the Site includes <br /> the following: <br /> • Four—330 gallon above ground storage tanks (used oil — 01 through 04) <br /> • Four—220 gallon above ground storage tank(waste antifreeze—Al through A4) <br /> Details of the used oil and waste antifreeze above ground storage tanks are provided in Table 1 <br /> and Figure 3. Site photographs, including images of the tanks, are provided in Appendix A. <br /> Manufacturer specifications are provided in Appendix C. <br /> 2.2.1 Secondary Containment <br /> The hazardous waste tank systems are located within 2 cross-linked polyethylene (XLPE), <br /> aboveground secondary containment tanks within the Drain Building (see Figures 2 and 3). <br /> Hazardous Waste Tank Assessment Stockton,CA <br /> Auto Parts Group—Pick-N-Pull 2 Project No.211283 <br />
