Groundwater monitodng test shall be performed <br />quarterly at all downgradient private wells at risk. Where detectilile VOCs have historically <br />been reported, bottled water shall continue to be supplied by the applicant (as is currently <br />being done for two affected households) until the well sample =t,1ical results show no <br />detectable VOCs for four consecutive quarterly sampling evenlS. Other offsite private wells <br />such as the CYA wells that have not been adversely affected by dle plume shall continue to <br />be monitored and ifVOC-contamination is reported then replace::nent water shall be provided <br />by the applicant, if requested. For wells within the footprint of !be plume, institutional <br />controls such as notification to current and future landowners regarding risks of installing <br />production wells shall be implemented as part of the local well ~tting process. <br />Proposed as Part of the Project: <br />The applicant has agreed to incorporate the conditions detailed i::t the discussion of Impact <br />E.1, above. . <br />Aeration and Treatment of Chlorinated Hydro-carbon Contmrinated 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 />Conceotration of Contaminants in mglkg: <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 10 I <br />1,2 Dichloroethane -2.0 x 10-1 <br />I, I Dichloroethane -1.0 x 10-2 <br />1,1,1 Trichloroethane -1.0 x 101
