Grand Junction Uranium Mill Site (Refinery, Concentrate Plant, and Pilot Plants)
Grand Junction Uranium Mill Site is located in Mesa County, Colorado. This site is covered as a DOE facility for three separate areas. The Refinery is covered as a DOE facility for 1943-1946 which means workers for these years are eligible to file Part B and Part E claims. Workers at the Concentrate Plant are covered as DOE employees for 1948, which means workers for this year are eligible to file Part B and Part E claims. Workers at the Pilot Plants are covered as DOE employees for 1953-1958 which means workers for these years are eligible to file Part B and Part E claims.
Workers covered by RECA 5 (Radiation Exposure Compensation Act (RECA)) at any Grand Junction Uranium Mill are also eligible to file a Part E EEOICPA claim.DOE says "The Manhattan Engineer District (MED) constructed a uranium refinery (mill) to produce uranium concentrate from “green sludge here in 1943 which it operated through 1946.” This location also served as the headquarters for the U.S. Atomic Energy Commission’s (AEC) uranium-procurement program from 1947 through 1970 and was known as the Grand Junction Office. One of the principal functions of the site was the receipt, sampling, and analysis of uranium and vanadium concentrates from the numerous ore-processing operations in the western United States. In 1951, the AEC constructed a concentrate sampling plant, assay laboratory, and two ore-testing pilot plant mills at this facility. Furthermore, the AEC established a sampling and assaying station for the receipt of uranium ores at Grand Junction. Concentrates produced by mills were delivered in steel drums to Grand Junction, where they were received, weighed, sampled, and assayed as the basis for payment to the mills under the terms of their respective contracts.
On September 30, 2001, the Department of Energy transferred ownership of the Grand Junction property to the Riverview Technology Corporation. The DOE, however, continues to lease portions of the site and provides some on-going remediation services as well as Long-Term Surveillance and Maintenance at the site." (credit DOE)
