Thornton Rd. RO#: 550 <br /> Lodi, CA., 95242 CUF#: 12992 <br /> The San Joaquin County Environmental Health Department (EHD) has reviewed Corrective <br /> Action Plan (CAP) as submitted by your consultant, Advanced GeoEnvironmental Inc (AGE) <br /> and has the following comments. <br /> The CAP is a large comprehensive document that includes a detailed history of the site <br /> from the time the underground storage tanks (UST) were removed in October 1998 to the <br /> most recent monitoring well and vapor extraction test well installations in November 2006. <br /> Also included in the CAP was a discussion of the soil and ground water contamination <br /> assessment and evaluations of the recent vapor extraction test and a feasibility study for the <br /> remedial alternatives that could work for this site. <br /> Based on feasibility and cost comparisons of the remedial alternatives, your consultant has <br /> concluded that in-situ soil vapor extraction (SVE) has the greatest feasibility to remediate <br /> the soil and that in-situ air sparging (IAS) was the most feasible remedial alternative for <br /> mitigating the petroleum impact to the ground water. The EHD concurs. <br /> Please submit a Remediation Action Plan by July 31, 2007 that details the number, location, <br /> and specifications for all of the remedial wells needed complete the corrective action. <br /> You may contact Michael Infurna, Senior REHS at (209) 468-3454 if you have any <br /> questions or wish to discuss the site. <br /> Donna H�eran, REHS, Director <br /> Envir � <br /> oni� "v`al Health <br /> �pa nt <br /> Michael J.
