FUSRAP Background: Under FUSRAP, the U.S. Army Corps of Engineers is cleaning up sites with contamination resulting from the Nation’s early atomic energy program. FUSRAP was initiated in 1974 to identify, investigate and, if necessary, clean up or control sites throughout the United States contaminated as a result of Manhattan Engineer District or early Atomic Energy Commission activities. Both the Manhattan Engineer District and the Atomic Energy Commission were predecessors of the U.S. Department of Energy.
