The U.S. Department of Energy’s (DOE) Office of Environmental Management (EM) mission is to address the nation’s Cold War environmental legacy resulting from decades of nuclear weapons production and government-sponsored nuclear energy research. This legacy includes some of the world’s most dangerous radioactive sites with large amounts of radioactive wastes, spent nuclear fuel (SNF), excess plutonium and uranium, thousands of contaminated facilities, and contaminated soil and groundwater.
The Office of Environmental Management Story
As the largest environmental cleanup program in the world, EM has been charged with the responsibility of cleaning up 107 sites across the country whose area is equal to the combined area of Rhode Island and Delaware.
The Budget & Planning Office manages, integrates and coordinates planning and budget support for the Department of Energy’s Office of Environmental Management.
