A Includes site characterization; environmental, health, and safety; remedial action for site design, acquisition, construction, and field management; vicinity property design and construction; surveillance and maintenance; technology development, and project management allocation.
   B The Ambrosia Lake (Phillips) mill generated about 3.1 million tons of tailings. Some 0.4 million tons were used to backfill underground mines.
   C Combined Belfield and Bowman cost was $10,239,000. The former uranium ore processing sites were not remediated under the UMTRA Program. Lignite ash produced at these sites was processed at mills in Colorado and New Mexico.
   D Uranium ore was not processed at the Burrell site. Radioactively contaminated materials at this site were stabilized on site for economic reasons.
   E Ore processing data are not available for the Canonsburg facility. Total cost includes Canonsburg and Burrell remediation. Cost for Unit of Radiation Avoided includes Canonsburg and Burrell sites.
   F A portion of the Cheney Disposal Cell will remain open as late as 2023, or until filled. Disposal cell radioactivity will be determined at that time.
   G Radioactively contaminated materials from Monument Valley, Arizona, mill site were relocated/stabilized at the Mexican Hat, Utah, disposal cell.
   H Includes uranium produced at the Rifle mill from Green River and Slick Rock uranium-upgrader slimes and Belfield lignite-ash mill-feed product.
   I Radioactively contaminated materials from the Riverton, Wyoming, mill site were relocated/stabilized at the UMETCO uranium facility in the Gas Hills Uranium Mining District, Wyoming.
   J Includes the Slick Rock uranium mill site and the Slick Rock uranium concentrator site.
   -- = Not applicable.
   Note: The Uranium Mill Tailings Radiation Control Act of 1978 (UMTRCA) provided for regulation of uranium mill tailings and established the Title I program. The U.S. Department of Energy conducted the Uranium Mill Tailings Remedial Action Project (UMTRA) under that authority.
