Bluewater Uranium Mill

First Title II Uranium Facility Accepted by US DOE for Long-term Operation and Maintenance.

The Bluewater Uranium Mill was the second-largest Title II uranium processing facility in the Western Hemisphere and the first post-closure site to be accepted by the US Department of Energy for long term operation and maintenance. The plant, owners and operated by Anaconda Minerals discontinued operations in 1979.

Today, the Bluewater, New Mexico, Disposal Site is managed by the U.S. Department of Energy Office of Legacy Management under Title II of the Uranium Mill Tailings Radiation Control Act of 1978. 

Primary Technical Contractor, Remedial Design, and Regulatory Support

ARCO began decommissioning the mill in 1989 and began site reclamation in 1991. By 1995, all mill tailings, contaminated soils, demolished mill structures, and contaminated vicinity property materials were encapsulated in on-site disposal areas. These areas are the main tailings disposal cell, the carbonate tailings disposal cell, an asbestos disposal area, a disposal area that also contains a polychlorinated biphenyl (PCB) disposal cell, and two small former dumps. More than 90 percent of the total tailings material is encapsulated in the main tailings disposal cell.
