The station formerly dispensed diesel fuel in addition to <br /> i4 regular, unleaded, and premium unleadedaso <br /> g line. The fuels were . <br /> f; stored on site in six underground storage tanks: four 6,000- <br /> F <br /> *. gallon and two 12,000-gallon tanks. The four 6,000- <br /> gallon tanks <br /> N had been in use for the past 27 years, while the two 12,000- <br /> r gallon tanks had only been in service for the last 7 years. " <br /> c There are no known septic tanks in the area, and all underground <br /> 3' utilities have been marked in the street by the appropriate <br /> �a <br /> utility companies. <br /> On March 17, 1987, all buildings, um is <br /> P P lands, underground <br /> �s fuel storage tanks and product lines were removed (Figure 2) . <br /> x <br /> During the tank removal procedure, the San Joaquin Local Health <br /> District '(SJLHD) inspected the excavation and determined that <br /> . hydrocarbon contamination was evident. However, according to the <br /> site operator, Mr. Knowles, inventory records indicated no <br /> l <br /> produet .discrepancies had occurred since the station began <br /> operation, Soil samples were collected from the tank excavation <br /> !~ on March 17, 1987, and again on April 10, 1987 (Appendix YV) , <br /> 4 with subsequent laboratory analyses prompting the SJLHD to <br /> request an initial groundwater investigation.
