. SITE CONTAMINATION WORK PLAN J & L MARKET 8115 South E1 Dorado Street French Camp, CA 95231 1 .0 INTRODUCTION I 1 . 1 Background J & L Market is a gasoline and diesel station and convenience store located at the intersection of Mathews Road and South El Dorado Street in French Camp, California. The Market is owned and operated by James Fisk. Mr. Fisk retained Elite IV Contractors of Stockton, California to remove and replace the underground fuel storage tanks and remodel the service station portion of the property. The scope of work called for removing the existing tanks from the western corner of the property, as well as the product lines and dispenser islands from, the east ( front) side of the property (Figure 2 ) . The new tanks are to be installed in the northern corner of the property. 1 .2 Tank Removal Elite IV removed two 10 , 000-gallon unleaded gasoline storage tanks and one 2 , 000-gallon unleaded gasoline storage tank from thb property on November 8, 1995 (Figure 1 ) . The removal was witnessed • by the French Camp Fire Department and San Joaquin County Environmental Health Division. The northern half of the excavation for the new tanks was dug prior to the removal of the old tanks, but the southern half could not be dug until the product line/dispenser trenches had been sampled and examined for evidence of soil contamination. When this was done on November 8, gasoline- contaminated soil was observed in the eastern trench (dispenser island #2 ) , preventing further excavation until laboratory analysis of the trench samples had been performed and a work plan for removal of contaminated soil had been prepared. 1 . 3 Laboratory Results of Product Line Samples Six samples were gollected from the product line trenches and delivered to Excelchem Labs in Roseville, California. The four samples from the dispenser island area were analyzed on 24-hour turnaround for Total Petroleum Hydrocarbons as gasoline and Volatile Aromatic Hydrocarbons (benzene, toluene, ethylbenzene, and xylene [BTEX] ) . A copy of the laboratory report is attached. Samples JL-P-4 through JL-P-6 were non-detect for all analytes, as was the composite sample from the stockpile. However, hydrocarbons were detected in sample JL-P-3, which was collected from the south end of island #2 (Figure 2 ) . Gasoline was detected at a concentration of 5, 500 mg/kg, toluene was detected at 55 mg/kg, . ethylbenzene was detected at 62 mg/kg, and xylene was detected at 460 mg/kg. Benzene was reported as not detected, but due to the high concentrations of other hydrocarbons, the laboratory was
