Energy Fuels Resources Corporation
Proposed Piñon Ridge Uranium Mill

A uranium mill is being proposed for construction in Montrose County by Energy Fuels Resources Corp. The proposed site for the mill is approximately 12 miles west of Naturita in the Paradox Valley. The proposed mill would be the first uranium/vanadium mill built in the United States in more than 25 years.

Before construction can begin, the Colorado Department of Public Health and Environment must review and approve the company's applications for a radioactive materials license and for air emissions permits. In addition, the U.S. EPA must approve construction of material impoundments at the mill site.

More information on these actions can be found below.


Radioactive Materials License

The Colorado Department of Public Health and Environment’s Hazardous Materials and Waste Management Division approved the radioactive materials license on January 5, 2011.

Air Permit

The proposed facility also must obtain an air permit from the Colorado Department of Public Health and Environment’s Air Pollution Control Division. Proposed facilities must demonstrate that they will not cause or contribute to violations of the National Ambient Air Quality Standards (NAAQS). For more information on various aspects of the air permit and the permitting process, please follow these links:

EPA Approval of Impoundments

The U.S. EPA has made notice its intent to approve construction of uranium byproduct material impoundments at the mill site, and has established an informal public comment period on its approval through April 8, 2011. More information on EPA's approval can be found at the following site:

 
 

Additional materials and documents will be posted here as they become available.
