The Nuclear Regulatory Commission has approved a plan by United Nuclear Corp. (UNC) to dispose of mine waste from the Northeast Church Rock mine site in New Mexico at the company’s nearby uranium mill and tailings disposal site.

Based on a review of U.S. Atomic Energy Commission (AEC) records and available data from numerous agencies, there are an estimated 4,225 mines across the country that provided uranium ore to the U.S. government for defense-related purposes between 1947 and 1970. To aid in the cleanup of these legacy uranium mines and establish a record of their locations and current conditions, the Defense-Related Uranium Mines (DRUM) program was established within the Department of Energy’s Office of Legacy Management (LM).

When the Department of Energy, the state of Idaho, and the Environmental Protection Agency signed a federal facility agreement and consent order in December 1991, the agencies outlined a plan to investigate and clean up, if necessary, more than 500 individual waste areas within the 890-square-mile Idaho National Laboratory (INL) Site, which was established in 1949 to design, build, and test nuclear reactors.

Soil and groundwater contamination at the Hanford Site’s 100-BC Area will be treated under a record of decision (ROD) signed by the Department of Energy and the Environmental Protection Agency, with the concurrence of the Washington State Department of Ecology.
