Three steel underground storage tanks (UST) are located adjacent to the carwash building. Two fuel dispensing islands are located west of the UST (Figure 2). BACKGROUND In January 1987, Canonie Environmental, of Sto kton California, trenched and collected two soil samples from beneath the product piping adjacent to the western fuel dispensing island, after the Taiping failed a pressure test. Soil analysis indicated total petroleum hydrocarbon (TPH) concentrations ranged from below detection limits (BDL) to 1,500 parts-per-million (ppm). Subsequent to the soil sampling, approximately 3 to 5 cubic yards of petroleum-bearing soil were excavated adjacer t to the western dispenser island, under the supervision of the San Joaquin County Enviro mental Health Department (SJCEHD). The excavation was backfilled with clean fill material, The UST are approximately 30 years old, however, they were lined with fiberglass in November 1987. The product and vapor,lines were replaced after the UST fiberglass work. 93A42C.RER
