The Federal Facility Compliance Act, also known as FFCA, which was passed by Congress in 1992, is another amendment to the Resource Conservation and Recovery Act, also known as RCRA. RCRA contains specific restrictions on hazardous waste land disposal. These restrictions include treatment standards that must be met before hazardous waste is stored or disposed. In general, U.S. Department of Energy sites that stored mixed waste were not meeting these standards because they did not have the ability to treat mixed waste.

FFCA required the Secretary of Energy to create Site Treatment Plans for each facility where DOE stores or generates mixed wastes. These plans identify how DOE will provide the necessary mixed waste treatment capacity, including schedules for opening new treatment facilities.  The U.S. Deparment of Energy has more information.
