Description

The U.S. Department of Energy (DOE) is responsible for cleanup activities at the Fernald Environmental Management Project (FEMP) site in southwestern Ohio. The 425-hectare site consists of a former 55-hectare Production Area, an adjacent Waste Storage Area and various support facilities. From 1952 until 1989, the FEMP processed uranium into metallic {open_quotes}feed{close_quotes} materials for other DOE facilities in the nation`s defense program. In accordance with the Comprehensive Environmental Response, Compensation and Liability Act (CERCLA), the FEMP site is currently listed on the National Priorities List (NPL). To facilitate an expeditious cleanup effort, environmental issues associated with site cleanup are being ... continued below

Description

The U.S. Department of Energy (DOE) is responsible for cleanup activities at the Fernald Environmental Management Project (FEMP) site in southwestern Ohio. The 425-hectare site consists of a former 55-hectare Production Area, an adjacent Waste Storage Area and various support facilities. From 1952 until 1989, the FEMP processed uranium into metallic {open_quotes}feed{close_quotes} materials for other DOE facilities in the nation`s defense program. In accordance with the Comprehensive Environmental Response, Compensation and Liability Act (CERCLA), the FEMP site is currently listed on the National Priorities List (NPL). To facilitate an expeditious cleanup effort, environmental issues associated with site cleanup are being managed under five operable units. This paper summarizes the risk assessment strategy employed to determine baseline human health risks associated with K-65 and metal oxide residues currently stored in Operable Unit 4. The K-65 and metal oxide residues were generated during the 1950s as a result of the extraction of uranium from uranium-bearing ores and concentrates. These residues are currently stored within Operable Unit 4 in concrete silos. Silos I and 2 contain approximately 6,120 cubic meters [m{sup 3}] (8,005 cubic yards [yd{sup 3}]) of K-65 residues, while silos 3 contains approximately 3890 m{sup 3} (5,080 yd{sup 3}) of cold metal oxides. These concrete silos are beyond their design life and require remedial action. The risk assessment conducted for Operable Unit 4 constitutes the first detailed human health risk assessment to be approved by the Environmental Protection Agency (EPA) for the CERCLA clean-up effort at the FEMP Site. This paper discusses the FEMP`s use of a Risk Information Quality Objective process in concert with the traditional risk assessment approach to determine baseline risk to human health and the environment posed by Operable Unit 4. A summary of the baseline risks to human health is also presented.
