Preserving the past, preparing for the future: A broad perspective on long-term stewardship
Three optional tours are offered during the 2018 Long-Term Stewardship Conference. Two of the tours will visit the Grand Junction, Colorado, Disposal Site. The third will visit the Moab, Utah, Uranium Mill Tailings Remedial Action (UMTRA) Project.
Monday, August 20
1:30 p.m. – 4:15 p.m.
Thursday, August 23
1:30 p.m. – 4:15 p.m.
The Grand Junction disposal site is located about 18 miles southeast of Grand Junction. Construction of the site began in 1990. By the end of 1994, contaminated materials from the decommissioned Climax Uranium Mill processing site located south of downtown Grand Junction and vicinity property materials (which had been temporarily stored at the processing site) were transported to the disposal cell.
About 4.4 million cubic yards of contaminated materials were placed in the cell as the U.S. Department of Energy (DOE) completed cleanup of the vicinity properties in 1998.
The site continues to receive contaminated materials generated from utility and road work projects by local municipalities, as well as materials from other former UMTRA sites.
Participants will have the chance to see the cell operations and receiving area, the de-contamination area, the Enhanced Cover Assessment Project, and the disposal cell itself.
The tour is open to up to 40 participants on a first-come, first-serve basis. All tour participants must wear long pants and sturdy, closed-toe footwear (no sandals). Expect hot and dry weather typical of late August in Grand Junction, with a possibility for afternoon showers. Hats, sunscreen, and water bottles are recommended.

7:30 a.m. – 5:00 p.m.
The Uranium Reduction Company constructed the Moab, Utah, mill in 1956 and operated it until 1962, when the assets were sold to Atlas Minerals Corporation. Uranium concentrate was sold to the Atomic Energy Commission through December 1970 for use in national defense programs. After 1970, production was primarily for commercial sales to nuclear power plants. During its years of operation, the mill processed an average of about 1,400 tons of ore per day. The milling operations created process-related wastes and tailings. These tailings were pumped to an unlined impoundment on the western portion of the property that accumulated over time, forming a pile more than 80 feet thick.
The scope of the Moab UMTRA Project is to relocate mill tailings and other contaminated materials to an engineered disposal cell constructed near Crescent Junction, Utah. Active remediation of groundwater at the site is also part of the project. The DOE Office of Environmental Management in Grand Junction has primary responsibility for managing the Moab UMTRA Project.

Participants will visit the Moab site in the morning, followed by a lunch stop in the town of Moab. In the afternoon, the tour will stop at the engineered disposal cell in Crescent Junction.
The tour is open to up to 30 participants on a first-come, first-serve basis. All tour participants must wear long pants and sturdy, closed-toe footwear (no sandals). Expect hot and dry weather typical of late August in Moab, with a possibility for afternoon showers. Hats, sunscreen, and water bottles are recommended.
