PHS/EHD has prepared the following comments for <br /> your consideration. <br /> Local Oversight Program <br /> This site was placed into the Local Oversight Program, as per the 1993-1994 contract <br /> between PHS/EHD and the State Water Resources Control Board (SWRCB) which <br /> states that PHS/EHD will oversee the investigation of all suspected underground storage <br /> tank release sites within the county. A suspected release includes PHS/EHD staff <br /> observations made during an inspection of tank removal activity or sample results from <br /> soil collected in the area of the former tank. The site was placed into the Local <br /> Oversight Program based on PHS/EHD staff observations during the March 10, 1989 <br /> over excavation in the area of former tank #4. <br /> Also, the detection limits used to characterize the former tank #4 area at the time of <br /> tank removal were significantly elevated. While the eastern area was re-excavated, the <br /> western area was not. <br /> Furthermore, the sample which was collected from the tank #4 over excavation sidewall <br /> at 13.5 feet below ground surface evidenced residual soil contamination, a heavy oil in <br /> the carbon range of C15 - C28 which could not be quantitated. Diesel is typically <br /> detected in the C12 - C22 range. <br /> The soil contamination associated with the oil-water sump also indicated that the area <br /> should be investigated further. <br /> A Di.kion of San Joaquin Counlp Health Care Services <br />
