nuclear waste sitesUpdated June 2013

The mission of NCSL’s Nuclear Legislative Workgroup (NLWG) is to provide legislative members with the opportunity to learn about the cleanup of federal nuclear weapons production and research facilities, the transportation and storage of radioactive wastes, and nuclear energy issues that affect our nation and states. This fact sheet is part of this effort.

The U.S. Department of Energy is responsible for the safe cleanup and long-term stewardship of the nation’s nuclear weapons production and research facilities. Radioactive and chemical waste, contaminated soil and water, and other hazardous materials at these sites pose significant risks to humans and the environment.

DOE’s Office of Environmental Management is primarily responsible for initial cleanup of these federal facilities. After the Environmental Management cleanup is complete, DOE’s Office of Legacy Management oversees long-term surveillance and maintenance of the sites.

Currently, DOE oversees 17 Environmental Management sites in 11 states and 90 Legacy Management sites in 29 states.
