such as notification to current and future landowners regarding risks of installing production <br /> wells shall be implemented as part of the local well permitting process. <br /> j. 40(E.9) <br /> Proposed as Part of the Project: <br /> The applicant has agreed to incorporate the conditions detailed in the discussion of impact <br /> E.1, above. <br /> Aeration and Treatment of Chlorinated Hydro-carbon Contaminated Soils: For chlorinated <br /> hydrocarbon-contaminated soils,the on-site treatment of contaminated soils by aeration will <br /> be managed so as to minimize exposure to on-site employees as well as off-site residents. <br /> Volumes of soils received,time of storage, and/or the types of contaminants and levels of <br /> contamination present will all be limited to assure exposure risks are no greater than 10-6. <br /> The following limitations apply: <br /> Acreage of Chlorinated Hydrocarbon-Contaminated Soil Treatment-0.5 acres <br /> Concentration of Contaminants in mg/kg: <br /> Volatile Organic Compounds <br /> Benzene-5.0 x 10-1 <br /> Toluene-6.9 x 10-1 <br /> Ethylbenzene-9.9 x 102 <br /> Xylene-1.3 x 104 <br /> Chlorinated Hydrocarbons <br /> Trichloroethylene-1.0 <br /> Perchloroethylene-1.0 x 101 <br /> 1,2 Dichloroethane-2.0 x 10-1 <br /> 1,1 Dichloroethane-1.0 x 10-2 <br /> 1,1,1 Trichloroethane-1.0 x 101 <br /> Methylene Chloride-1.0 <br /> PAHs(carcinogenic)-7.5 x 101 <br /> PCBs-1.0 x 101 <br /> PCDD/Fs-3.0 x 10-5 I <br /> Cresol-4.0 x 103 <br /> Metals <br /> Arsenic-5.0 x 101 <br /> Beryllium-7.5 <br /> Cadmium-1.0 x 101 <br /> Chromium III-4.0 x 102 <br /> Copper-2.2 x 102 <br /> Lead-5.0x101 <br /> Mercury-2.0 <br /> Nickel-2.0 x 102 <br /> Zinc-9.2 x 101 <br /> To mange both on-and off-site impacts due to the on-site aeration or treatment of <br /> contaminated soils,the concentration of chlorinated hydrocarbons in the soil will be restricted <br /> to lower levels than those assumed in the health risk assessment contained in the Forward <br /> Final EIR (1993). <br /> San Joaquin County UP-00-7, ER-00-2\Fornrard.
