Trucking <br /> 3514 Newton Road, 8toakton, California <br /> i <br /> 3 <br /> i <br /> Dear Mr. Knoll: <br /> According to .information provided by your offiGe, :at least one of � <br /> the underground storage tanks <br /> g g (UST's) at the refOprenced site was � <br /> used to contain diesel fuel. Therefore, selected sgil samples from <br /> the borings will be analyzed for TPN as diesel in '�additiop to TPH <br /> as gasoline and HTE&X. <br /> Your office also advised that we should consider a .boring north of <br /> the UST's, south of the pump islands. GeoAudit proposes to locate <br /> a boring near the southern portion of the pump islOnd, east of the <br /> UST's. This boring will be drilled instead of the )boring proposed <br /> for east side of the main structure, south Of the UST's on the <br /> original site plan. Precise boring locations will be illustrated in <br /> a report following the drilling and analysis. <br /> If you have any questions or comments, please connect Our office. <br /> sincerely, <br /> GEOLOGICAL AUDIT SERVICES, INC. <br /> ob Marty <br /> Project Geologist <br /> i <br /> cc: Nr- aohn Urrutia -- Bank of Stockton ' <br /> i <br /> •4 <br /> i <br /> ,I 1 <br /> •i i <br /> Environmental Services-Hydrogeology-Geotechnical Services I <br /> i <br />
