Superfund record of decision (EPA region 10): Eielson Air Force Base, Fairbanks-North Star Borough, AK, September 30, 1996
The decision document presents the final remedial action selected for Eielson Air Force Base (AFB), Alaska. The sitewide investigation at Eielson AFB evaluated basewide contamination that is not confined or attributable to specific source areas identified and addressed in the FFA as well as cumulative risks to human health and the environment posed by contamination on a sitewide basis. Garrison Slough is the only one that poses an unacceptable risk to human health and the environment. Polychlorinated biphenyls (PCBs) were found in the fish tissue and sediments of Garrison Slough. Soils in a trench adjacent to Garrison Slough were contaminated with PCBs and appear to be the source of contamination to slough sediments via surface water runoff. The major components of the selected remedy include: Fishing restrictions in Garrison Slough; Fish control device near the downstream edge of Eielson AFB; Excavation of contaminated soils and sediments with concentrations greater than 10 mg/kg PCBs; Onsite disposal of material with PCB concentrations less than 50 mg/kg; Offsite disposal or treatment of materials with PCB concentrations greater than 50 mg/kg in accordance with the Toxic Substances Control Act (TSCA), 40 CFR part 761; and Environmental monitoring of soils, sediments, surface water, fish, and groundwater.
