State Highway 99 E. Frontage Rd. aka Victor Meats Property <br /> Dear Mr. Knoll: <br /> Please find the site history and the report of findings from the last sampling event of June 14,2004. <br /> RECENT HISTORY OF THE SITE <br /> This site was used for a number of years as a meat processing facility for Victor Meats.The property <br /> and all of the attached improvements were purchased by Woodbridge Partners Inc.at a court ordered <br /> sale in 1999. One waste oil tank and two underground diesel fuel storage tanks of 12000 gallons and' <br /> 8000 gallons each were included as attached improvements to this forced sale. <br /> On August 17,2000,Ford Construction Co.removed the three afore mentioned underground storage <br /> tanks under a San Joaquin County UST closure permit issued on August 8, 2000. Under the <br /> supervision of the consultant, Kleinfelder, Inc., twelve soil samples were extracted from the area <br /> under the tanks and the soil spoil stockpile. Soil samples were transported under Chain of Custody <br /> to Alpha Analytical Inc.for analysis.Groundwater was not encountered during the removal of these <br /> tanks. <br /> Results of Tank Removal Soil Samples <br /> Analysis by EPA Method 8015B/DHS LUFT yielded concentrations of TPHd to 18000 mg/Kg for <br /> the sample from under the south end of the 12000-gallon diesel fuel tank(Sample 21371-EB-S-12K- <br /> 12 ft.). Low concentrations to 570 mg/Kg were found on the north end of this diesel storage tank. <br /> Low concentrations of TPHd were found in the stockpiled excavation spoil.A low concentration of <br /> MTBE was indicated in a soil sample extracted from under the south end of the 12000-gallon diesel <br /> tank <br /> Only extremely low levels of heavy metals were indicated in the-sample from the waste.oit tank and <br /> are most likely not a result of a waste oil spill. <br /> Conclusions From Tank Removal Soil Sample Analysis <br /> The concentration of TPHd is the highest under the south end of the 12000-gallon diesel tank.Lower <br /> r� concentrations were found to decline toward the north end of the tank.Most likely a spill occurred <br /> near the south end of the 12000-gallon diesel tank. .. <br /> l <br />
