Nuclear waste oversight

Our Nuclear Waste Program oversees cleanup at the Hanford Nuclear Reservation near Richland, Washington. The site produced plutonium for military defense between 1943 and 1989, and later served as a storage facility for other radioactive wastes. Today, Hanford is one of the most complex and toxic cleanup sites in the nation. Our role is to regulate cleanup efforts. We also regulate several other mixed waste (which includes both dangerous and radioactive waste) sites in Washington and the Puget Sound Naval Shipyard. Learn what we're doing to keep dangerous and radioactive cleanup on track, and communities and the environment safe.
