The Kirkland and Ellis letter also states that the December 8, 1995 <br /> State Resources Control Board (SWRCB) Walt Petit memo and the Lawrence <br /> Livermore National Laboratory (LLNL) report on leaking underground fuel tanks <br /> abrogates the necessity of completing the monitoring plan itself. <br /> PHSIEHD concurs that the PCP contamination is unrelated to the UST closure. <br /> PHSIEHD, acting as the local enforcement agency for this cleanup, is recommending <br /> remediation of this area. If you choose to not remediate this area, PHSIEHD will <br /> refer this issue to the Department of Toxic Substances Control. <br /> The solvent contamination is consistent with the presence of a waste oil tank and <br /> may be related to the UST closure. The constituents of the solvent groundwater <br /> contamination in DMW 5 detected in the May 2,1995 sample are carbon tetrachloride <br /> .65 ppb, 1, 2 dichloroethane 40 ppb, and chloroform 3.8 ppb. This well is located in <br /> the former waste oil tank excavation. Solvents were not evidenced in the soil from <br /> DMW-5, leading to Dames & Mores' conclusion that the source of the solvent leak is <br /> not the waste oil tank. PHSIEHD has not been convinced to date that the solvent <br /> contamination is not from the waste oil tank. <br /> A Division of San Joaquin County Health Care 5en-ices <br />
