t <br /> SITE INVESTIGATION WORK PLAN <br /> 800 WEST CHURCH STREET VvU3F <br /> STOCKTON, CALIFORNIA <br /> Following completion of groundwater sampling, the boreholes will be backfilled to the ground <br /> surface using a tremie pipe and a bentonite/Portland Type II cement grout. The borings will then <br /> be completed to match the existing ground surface. <br /> 3.4 TASK 4: INVESTIGATION-DERIVED WASTE MANAGEMENT <br /> Investigation-derived wastes (IDWs), those materials generated during the process of sampling <br /> and investigation at the Site, will be managed in accordance with applicable regulatory <br /> requirements. IDWs are anticipated to include soil cuttings, decontamination fluids, personal <br /> protective equipment (PPE) and disposable sampling equipment. <br /> Management of IDW must comply with applicable regulations. Potential applicable regulations <br /> include the Resource Conservation and Recovery Act (RCRA), Clean Air Act (CAA), Clean <br /> Water Act (CWA), Safe Drinking Water Act(SDWA) and legally enforceable state regulations. <br /> Waste generated during implementation of the work will be containerized in USDOT-approved <br /> containers, labeled and temporarily stored in a secure area at the Site. The containers will be <br /> labeled including generator contact information, accumulation date and type of waste, e.g., purge <br /> water, solid waste and PPE. The IDWs will then be characterized to determine appropriate waste <br /> disposal options. <br /> i <br /> I <br /> 6 <br /> 5111 <br />
