Our responsibilities include long-term stewardship of 100 sites across the United States and Puerto Rico. However, we have a variety of programs related to the country’s nuclear defense and energy legacy, ranging from oversight of the administration and management of legacy contractor benefits to assessing the condition of 2,500 defense-related uranium mines on federal public land. Use the links below to explore LM’s diverse programs.

Applied Studies and Technology (AS&T)

DOE established the Environmental Sciences Laboratory (ESL) in Grand Junction, Colorado, in 1991 to support its programs. AS&T scientists use the ESL to perform applied research and laboratory-scale demonstrations of soil and groundwater remediation and treatment technologies.

Defense-Related Uranium Mines Program

The U.S. Department of Energy (DOE) Defense-Related Uranium Mines (DRUM) Program is a partnership between DOE, federal land management agencies, and state abandoned mine lands (AML) programs to verify and validate the condition of 2,500 defense-related uranium mines on federal public land by the year 2022. The program builds on DOE’s DRUM Report to Congress effort, which found that 4,225 purchase records exist across the nation. These mines provided uranium ore to the U.S. Atomic Energy Commission for defense-related activities that occurred between 1947 and 1970 and most are abandoned.

Environment, Safety, Health, and Quality (ESH&Q)

Our Environment, Safety, Health, and Quality programs protect our workers, the public, and the environment and integrate quality into the daily operations of our programs and projects.

Post-Closure Benefits

The Legacy Management Post-Closure Benefits (PCB) Program includes the development, implementation, and oversight of the Department’s policy concerning the continuation of contractor pension and medical benefits after the closure of applicable DOE sites/facilities. This includes oversight of the administration and management of legacy contractor benefits in a fiscally responsible and effective manner. The primary program objective is to ensure a seamless transition of benefits administration after closure. This program is handled by the Office of Business Operations within Legacy Management.

Uranium Leasing Program

LM currently manages the Uranium Leasing Program and continues to administer 31 lease tracts, all located within the Uravan Mineral Belt in southwestern Colorado. Twenty-nine of these lease tracts are actively held under lease and two tracts have been placed in inactive status indefinitely. Administrative duties include ongoing monitoring and oversight of leaseholders’ activities and annual inspections to identify and correct safety hazards or environmental compliance issues.
