Henderson <br /> and I have reviewed letter dated December 3, 2008, by San Joaquin County Environmental Health Department <br /> (EHD). The EHD had recommended that the conductor casing for MW-1D be set at seventy feet below surface <br /> grade (bsg)instead of the proposed depth by Stantec Consulting Corporation (Stantec)of sixty-five feet bsg. The <br /> EHD concluded that Stantec is correct. The conductor casing should be set at the potential aquitard at <br /> approximately sixty-five feet bsg. This email documents concurrence by the EHD to set the conductor casing for <br /> MW-1 D at the proposed sixty-five feet bsg. The site geologist or engineer should verify that the bottom of the <br /> conductor casing has been set within the fine-grained unit. <br /> Vicki McCartney,Senior REHS <br /> San Joaquin County <br /> Environmental Health Department <br /> 600 East Main Street <br /> Stockton,California 95202 <br /> .Phone: (209)468-9852 <br /> 1/15/2009 <br />
