Muniappa Naidu <br /> - � <br /> San Joaquin County Environmental Health Department <br /> 1868 E. Hazelton Ave . <br /> Stockton , California 95205 <br /> Subject : Results of Additional Soil and Groundwater Sampling <br /> for Underground Storage Tank Closure <br /> Associated Tractor Service , Inc . <br /> 1323 W . Charter Way , Stockton, CA <br /> Dear Mr . Naidu : <br /> We have prepared this report on behalf of Ms . Margo Bentz-Ivers , the property owner of the <br /> subject site, which is occupied by Associated Tractor Service , Inc . This report describes the <br /> results of additional soil sampling and groundwater sampling to investigate conditions beneath <br /> a former underground gasoline storage tank (UST) . <br /> Background <br /> According to records in San Joaquin Environmental Health Dept . (EHD ) files a 1 ,000- <br /> gallon gasoline UST was last used in 1986 or 1987 and was removed without a permit in <br /> the spring of 1991 . The UST reportedly had a small hole in the bottom . The tankpit was <br /> then backfilled without any soil samples being collected . <br /> In October 1991 the Roy F . Weston company filed an UST closure permit application for <br /> soil sampling but apparently the work was not performed . In June 1992 , as requested by <br /> EHD , Hess & Hess construction filed a soil sampling workplan and another UST closure <br /> application . The workplan proposed collecting two soil samples from the tankpit with a <br /> hand auger . There is nothing in the EHD files to indicate that the proposed sampling work <br /> was done . Note , however , that the additional required UST closure information such as <br /> tank disposition record, etc . were filed with EHD . <br /> Additional UST Soil and GW Sampling Report <br />
