White Mesa Uranium Mill
Energy Fuels Resources (USA) Inc. (EFR) operates the White Mesa Uranium Mill, located approximately six miles south of Blanding. Prior to Energy Fuels Inc., taking ownership of the Mill in August, 2012, it was operated by Denison Mines (USA) Corporation from December, 2006 to August 2012. Proceeding Denison Mines, the facility was operated by International Uranium (USA) Corporation.
The Mill License was originally issued by the US Nuclear Regulatory Commission as a source material license under 10 CFR Part 40 on March 31, 1980. It was renewed by the NRC in 1987 and again in 1997. After the State of Utah became an Agreement State for uranium mills in August, 2004, the Mill License was reissued by the Executive Secretary as a State of Utah Radioactive Materials License on February 16, 2005.

On February 8, 2012 the U.S. Geological Survey published a report of an assessment of potential migration of radionuclides and trace elements from the White Mesa Uranium Mill to the surrounding areas. DWMRC preliminary review findings were shared with the public in a July 9, 2012 meeting in Blanding.
