摘要

This decision document presents the selected remedial action/corrective actionfor the Rocky Flats Environmental Technology Site (RFETS) Operable Unit (OU) 3: Offsite Areas, located near Broomfield and Westminster, Colorado. OU 3 is comprised of four Individual Hazardous Substance Sites (IHSS's): Contamination of the Land Surface (IHSS 199), Great Western Reservoir (IHSS 200), Standley Lake (IHSS 201) and Mower Reservoir (IHSS 202). Based upon the Baseline Risk Assessment and the Environmntal Risk Assessment contained in the RCRA Facility Investigation/Remedial Investigation (RFI/RI) Report of June 1996, DOE, the lead agency under CERCLA for OU 3, concludes that no action is appropriate for OU 3. The RFI/RI Report concludes that all IHSS's within OU 3 are already in a state protective of human health and the environment.
