ENVIRONMENT HEALTH <br /> 1831 16th Street PERMITISERVICES <br /> Sacramento, CA 95814 <br /> DOCUMENT REVIEW, NEW WEST PETROLEUM#9003 (SHELL BRANDED), <br /> 6437 BANNER STREET, LODI, SAN JOAQUIN COUNTY(CAO R5-2007-0709) <br /> I reviewed the Remediation Well Installation Work Plan (Workplan) dated 7 August 2008 <br /> from your consultant Closure Solutions, Inc. (CSI). The Workplan was submitted in response to <br /> the requirements of Order#16 of Cleanup and Abatement Order R5-2007 0709 (CAO), which <br /> states "Within 60 days of Water Board staffs approval of the FRP but no later than November <br /> 2008, begin implementation of the approved remedial actions." The Workplan incorporates <br /> recommendations from the Final Remediation Plan & Remediation System Design, which were <br /> approved by the 24 July 2008 Regional Board staff letter, and proposes installing six additional <br /> 4-inch diameter groundwater extraction wells (EW-6A, EW-7A, EW-713, EW-86, EW-913, and <br /> EW-1 OA, enclosed Figure 2) offsite to remediate the methyl tert-butyl ether (MtBE) groundwater <br /> plume in the A and B zones of the aquifer. The extraction wells will be completed with 4-inch <br /> diameter Schedule 80 polyvinylchloride (PVC) casing and screened from 5' to 25' below ground <br /> surface (bgs) in the A zone wells and 30' to 50' bgs in the B zone wells. <br /> The Workplan is approved as proposed. Please procure all necessary permits, and provide the <br /> San Joaquin County Environmental Health Department and myself at least three working days <br /> notice prior to starting fieldwork.
