Kirk Larson, PG, and Robert Trommer, CHG <br /> State Water Resources Control Board <br /> Division of Financial Assistance <br /> 1001 1 Street <br /> Sacramento CA 95814 CUF Claim # 14167 <br /> Subject: 7500 Eleventh Street W, Tracy, CA <br /> Five-Year Review Recommendations May 2011 <br /> The San .Joaquin County Environmental Health Department (EHD) has received and reviewed <br /> the fourth five-year review letter dated 19 May 2011 from Kirk Larson of the State Water <br /> Resources Control Board (SWRCB) Cleanup Fund (CUF) for the above-referenced site. The <br /> CUF recommended that the EHD consider the site for closure. <br /> The EHD has been considering the site for closure. By an oversight, an EHD letter dated <br /> 23 February 2010 was not uploaded to GeoTracker, an oversight that has now been corrected. <br /> In the letter, which was a response to a closure request, the EHD requested additional <br /> information to evaluate the closure request and to demonstrate plume stability and decline. By <br /> conversation with the consultant in December 2010, the EHD was informed that at the direction <br /> of the RP, no work had been done or was to be done pending receipt of reimbursement from the <br /> CUF. Since then a groundwater monitoring event was conducted in February 2011, for which a <br /> report dated 15 April 2011 has been received by the EHD. In the report, some but not all the <br /> information requested by the EHD was presented. <br /> The EHD will issue a letter directing submittal of the rest of the information and dropping the <br /> additional characterization of the leading portion of the dissolved plume. Upon receipt of the <br /> information, the EHD will complete the site closure evaluation. If the EHD can be of further <br /> service to you, your requests, questions and/or comments should be directed to Nuel <br /> Henderson at (209) 468-3436. <br /> Sincerely, / <br /> Nuel Henderson, PG <br /> Engineering Geologist <br /> Fourth Five-Year Review Comment Letter 2011.doc <br />
