Cameco Corp.'s Crow Butte uranium mine in Nebraska was allowed to continue operating, the U.S. Atomic Safety and Licensing Board decided.
The ruling ends a longstanding battle between the company and opponents, such as the Oglala Sioux Tribe, which sought to prevent a renewal of the mining license following its expiry in 2007. The mine has been operating on a temporary license since.
According to a report by the Rapid City (S.D.) Journal, the Nuclear Regulatory Commission had previously renewed the license. However, it was mandatory to also get confirmation by the Atomic Safety and Licensing Board.
Despite finding that the environmental analysis by the NRC did not meet the required standards in one area, the board refused to shut down mining operations at the site.
