Corrective Action Plan <br /> to the groundwater treatment system with double-contained piping. Electrical conduit <br /> will be provided between the treatment system and each co-extraction well. <br /> c Groundwater discharge piping will be installed to connect the treatments stem with <br /> ' either the sanitary sewer or the storm drain system, which ever is permitted. <br /> d) The remediation contractor will assure that all construction and installation actions are <br /> ' performed under appropriate regulatory permits and meet all applicable regulatory <br /> standards. <br /> ' e) The wellhead caps on extraction wells EW-1, EW-2, EW-3, and EW-4 will be designed <br /> for the co-extraction of groundwater and soil vapor. <br /> ' Task 4 Construct and Install SVE/Groundwater Extraction and Treatment Systems <br /> OST will provide and install the SVE/groundwater extraction/treatment technology as specified <br /> ' under Sections 5.2, 5.3,and 5.4. The proposed approximate location of the treatment system is <br /> as illustrated on the Remediation Site Map, Figure 5. <br /> ' Task 5 Perform Start-Up Monitoring <br /> 1) The contractor will provide soil vapor treatment system source testing, including field <br /> and laboratory analyses, as required by the SJVUAPCD Permit to Operate. <br /> ' 2) OST will provide groundwater treatment system start-up sampling and analyses as <br /> required by either the City of Manteca Public Works Department permit or the NPDES <br /> permit, whichever is applicable. <br /> Task 6 Perform Operations and Maintenance/Compliance Monitoring <br /> ' 1) Provide routine operations and maintenance (O&M) of the soil vapor and groundwater <br /> extraction and treatment systems, including GAC change-out labor, to maintain the <br /> design effectiveness of the respective systems. <br /> 2) Provide routine periodic effluent (groundwater) and emissions (air) sampling and <br /> analysis as specified by the NPDES and Air Board permits, respectively. <br /> Task 7 Perform Monthly/Quarterly Self-Monitoring Program <br /> ' 1) Perform monthly water level measurements and quarterly groundwater sampling. <br /> Assume groundwater will be sampled from five monitoring wells. <br /> I, s <br /> ' 701-1-2.cap OST Page 14 <br />
