Consolidated Forward Inc.. Landfill Page 11 Identified in This EER: (a) All applicable regulatory guidance originating after the Forward Landfill 1993 FIR and Austin Road Landfill 2000 FIR shall be implemented;all hazar ais materials shall be handled in accordance with local,State,and federal regulations. (b) The site HI CYT, SWPPP, Operations Manual, and Wet Weaker Plan shall serve to provide guidance in the use and handling of hazardous materials erring the operations of the facility. 39 (E.8) Identified in This EIR: Forward Landfill shall continue to test all known water supply wells within the area of the mapped and projected groundwater plume. Groundwater monito ing test shall be performed quarterly at all downgradient private wells at risk. Where detectable VOCs have historically been reported,bottled water shall continue to be supplied by the applicant(as is currently being done for two affected households) until the well sample analytical results show no detectable VOCs for four consecutive quarterly sampling events_ Other offsite private welts such as the CYA wells that have not been adversely affected by the plume shall continue to be monitored and if VOC•contamination is reported then replacement water shall be provided by the applicant,if requested. For wells within the footprint of t!le plume, institutional controls such as notification to current and future landowners regarding risks of installing production wells shall be implemented as part of the local well permitting process. 40 (E.9) Proposed as Part of the Project: The applicant has agreed to incorporate the conditions detailed in the discussion of Impact E.1,above. Aeration and Treatment of Chlorinated Hydro-carbon Contaminated Soils: For chlorinated hydrocarbon-contaminated soils,the on-site treatment of contaminated soils by aeration will be managed so as to minimize exposure to on-site employees as well as off-site residents. Volumes of soils received,time of storage, and/or the types of contaminants and levels of contamination present will all be limited to assure exposure risla are no greater than 10-6. The following limitations apply: Acreage of Chlorinated Hydrocarbon-Contaminated Soil Treatment—0.5 acres Concentration of Contaminants in mg/kg: Volatile Organic Compounds Benzene—5.0 x 10-1 Toluene—6.9 x 10-1 Ethylbenzene—9.9 x 102 Xylene— 1.3 x 104 Chlorinated Hydrocarbons Trichloroethylene— 1.0 Perchloroethylene— 1.0 x 101 1,2 Diehloroethane—2.0 x 10-1 1,1 Diehloroethane— 1.0 x 10-2 1,1,1 Trichloroethane— 1.0 x 101
