Coca-Cola Enterprises - West <br /> . Job No. 90054 <br /> Two steel USTs formerly existed at the site; one 10,000-gallon diesel UST and one 1,000-gallon <br /> gasoline UST. The diesel UST was reportedly installed m 1978 and the gasoline UST was <br /> installed in 1937. The site conditions at the time of USTEC's assessment including the location <br /> of the buildings, the former USTs, pnaduct delivery piping,vent piping, and fuel dispensers are <br /> presented on Figure 2. <br /> i:..; 2.2 PROJECT BACKGROUND <br /> CCE-W moved from their facility at 1100 Wilson Way in April, 1990. The USTs were removed <br /> as part of the abandonment procedures for the site. The excavation and removal of the 10,000- <br /> gallon and 1,000-gallon USTs, fuel dispensers, product delivery, and vent pipes was completed <br /> {" by Crisp Construction of Visalia, California, on April 19, 1990. All work was completed under <br /> the supervision of Quinn and Quinn Enterprises,Inc.,also of Visalia, California. Environmental <br /> �. support for the tank removal was provided by USTEC. <br /> sa. <br /> During the removal operations USTEC personnel collected a total of four soil samples. One <br /> soil sample was collected at a depth of 2 feet below the tank invert at each end of both USTs. <br /> Samples were analyzed for total petroleum hydrocarbons MPH) in accordance with <br /> Environmental Protection Agency (EPA) method 8015 modified for diesel and gasoline. In <br /> addition, samples were analyzed for the aromatic hydrocarbons benzene, toluene, ethylbenzene, <br /> and xylenes (BTEX) in accordance with EPA method 8020. <br /> V'4 Based on field work and analytical chemistry results,concentrations of diesel and gasoline were <br /> �+ found to be present in the soils in concentrations above State of California recommended clean- <br /> up levels (100 parts per million TPH) in the 1,000-gallon UST excavation. The results of this <br /> investigation were presented to Public Health Services, San Joaquin County, Environmental <br /> Health Division, in a Preliminary Underground Storage Tank Investigation Report (Appendix <br /> A). Follov:'-ig the preliminary UST investigation, USTEC was retained by CCE-W to conduct <br /> a contamination assessment at the Stockton site. <br /> 6 <br /> i� <br /> 2 <br /> f. <br /> MMIM <br />
