(TSGI). The Workplan proposes the abandonment of three monitoring <br /> wells (MW-1 through MW-3) remaining at the site. The groundwater analytical results for <br /> MW-1 through MW-3 were non-detect for petroleum hydrocarbons when last sampled in <br /> December 2006. The Workplan states the wells will be abandoned by pressure grouting at <br /> approximately 150 lbs per square inch each well to 2' below grade, then removal of the traffic <br /> boxes, and finally filling the resulting void with concrete to the surface. Soil cuttings and water <br /> generated during well abandonment will be characterized and properly disposed, or reused <br /> onsite as approved by Regional Board staff. A Well Destruction Report will follow within three <br /> weeks of completion of fieldwork, and will include a summary of fieldwork, analytical data, and <br /> permit / correspondence related to the Workplan. <br /> The Workplan is consistent with the Work Scope and Budget Proposal, DGS EAR Account <br /> Program, Buffalo Tank Corp, Stockton California, EAR Site No. R10-131 approved by me on <br /> 20 June 2011 , and is approved as necessary and appropriate to remove potential conduits to <br /> the aquifer, and to facilitate case closure. Please provide the San Joaquin County <br /> Environmental Health Department and myself with a minimum of 3 working days notice prior to <br /> start of fieldwork, and contact me by phone at (916) 464-4614 or by email at <br /> jbarton(a�waterboards.ca.gov if you have questions or comments. <br /> ames L.L.
