Site Code: 1627 <br /> 11396 Hwy 99 Frontage Rd N. RO#: 538 <br /> Lodi, CA. 95240 CUF#: 015089 <br /> On November 19, 2002, a San Joaquin County Environmental Health <br /> Department (EHD) representative met with you and your consultant to discuss <br /> this site and the continuing subsurface investigation of the fuel release from the <br /> former underground storage tanks (UST). <br /> Topics discussed at the meeting included: (1) your request for "No Further <br /> Action" (NFA) at the former diesel UST; (2) vertical and lateral impacted soil and <br /> groundwater delineation; (3) EHD concerns regarding the `supply well' and the <br /> `unused' drinking water well at the site; (4) identification of other nearby <br /> receptors; and (5) the placement of additional monitoring wells at and around the <br /> site. <br /> For clarification purposes, EHD will address each of these concerns in order <br /> given above: <br /> (1) Your request for "No Further Action"(NFA) of the former diesel UST; <br /> The former diesel UST site appears to be a candidate for closure consideration, <br /> but EHD requests the following additional information as the over-excavation was <br /> performed without EHD oversight, soil samples were not collected from the floor <br /> of the over-excavation, and additional work in the area is needed as part of the <br /> gasoline UST investigation. EHD requests that during the next phase of the <br /> gasoline release investigation, grab groundwater samples be collected near and <br /> down gradient of the former diesel UST and be analyzed for Total Petroleum <br /> Hydrocarbons as diesel (TPH-d) by EPA Method 8015m. If it can be verified that <br /> diesel is not present at a detection limit of 50 µg11 in the groundwater samples, no <br /> further investigation for the former diesel UST release will be required. Closure <br /> documentation for the diesel UST will be included in the gasoline UST closure <br /> documents when that investigation/remediation is completed. <br />
