BOX 3006 <br /> LODI, CA 95241-1910 MAY 21 1998 <br /> Re: CITY OF LODI PUBLIC SAFETY BLDG <br /> 230 ELM ST <br /> LODI, CA 95240 <br /> San Joaquin County Public Health Services, Environmental Health Division <br /> (PHS/EHD) has reviewed our Underground Storage Tank (UST) file for the <br /> above-referenced site. A 10,000 gallon diesel UST was removed in September <br /> 1987 and soil samples collected beneath the UST did not reveal the release of <br /> any contaminants from this UST. A 18,400 gallon diesel UST, which was <br /> proposed to be closed in place in 1986, remains out of use and not properly <br /> closed. Two monitoring wells were installed in October 1986 to investigate if <br /> there had been an unauthorized release of petroleum from the 18,400 gallon <br /> UST. One of the monitoring wells is located south of this UST which is generally <br /> the groundwater flow direction in this area. <br /> A 2,000 gallon dual walled UST was installed in August 1988 and removed in <br /> October 1988 because it failed precision testing. Excavation of contaminated <br /> soil from this UST occurred in December 1988 and soil sample results revealed <br /> that contamination from this UST had been removed. <br /> In a meeting at the site on February 26, 1998, PHS/EHD site mitigation staff <br /> requested a copy of all the sampling and analytical data from the monitoring <br /> wells since they were installed. PHD/EHD has not received any of the <br /> information to date. <br /> In a meeting at Lodi City Hall on May 13, 1998, PHS/EHD UST staff requested a <br /> closure-in-place (CIP) proposal for the 18,400 gallon UST be submitted by June <br /> 4, 1998. In a conversation on May 19, 1998, PHS/EHD UST staff requested a <br /> copy of all the sampling and analytical data of the monitoring wells be submitted <br /> with the CIP proposal by June 4, 1998. <br /> A Division of San Joaquin Counry Health Care Services <br />
