Box 100 <br /> Sacramento CA 95812-0100 <br /> Subject: 101 Wilson Way S., Stockton, CA <br /> Review Summary Report December 2014 Response CUF Claim No 8479 <br /> San Joaquin County Environmental Health Department (EHD) has reviewed Review Summary <br /> Report—Additional Work, Fifth Review(5th RSR), dated 09 December 2014 from Kirk Larson of <br /> the State Water Resources Control Board (SWRCB) Cleanup Fund (CUF) for above-referenced <br /> site. The CUF recommended that the EHD direct the responsible party (RP) to conduct regular <br /> groundwater monitoring of all wells to define the downgradient extent of groundwater <br /> contamination and to continue active remediation to achieve Policy goals in a timely manner. <br /> The CUF determined that other impediments to case closure identified by the EHD were <br /> satisfied by site conditions, specifically: 1) that adequate data is available for a conceptual site <br /> model, 2) that the secondary source has been removed through excavation and active <br /> remediation, 3) that the case meets the vapor intrusion criterion 2a by Scenario 1, and 4) that <br /> the case meets the direct contact criterion by Policy Criterion 3b. <br /> By letter dated 15 July 2014, the EHD had directed the RP to submit professional evaluations <br /> and opinions on all of the impediments to closure referred to above; in view of the CUF's <br /> professional evaluations provided in 5" RSR, the EHD will change the directives to completion <br /> of the assessment of the lateral extent of impacted groundwater and continuing groundwater <br /> remediation. The EHD will also modify the LTCP checklist and path to closure pages on <br /> GeoTracker to reflect the professional opinions rendered by the CUF. <br /> Questions or comments should be directed to Angelica Sandoval Marin at (209) 468-2807 or to <br /> Nuel Henderson at 209)468-3436. <br /> Sincerely, <br /> Angelica Sandoval Marin, REHS Nuel Henderson, PG <br /> Senior Registered Environmental Engineering Geologist <br /> Health Specialist <br /> 2014/15 Review Summary Report Response 0115 CUF Claim No 8479.doc <br />
