NRC EXTENDS COMMENT PERIOD TO MARCH 3 ON DRAFT ENVIRONMENTAL 

REPORTS FOR PROPOSED URANIUM RECOVERY FACILITIES 

 The Nuclear Regulatory Commission is extending until March 3 the public comment 

period on draft Supplemental Environmental Impact Statements (SEIS) for three proposed 

uranium recovery facilities in Wyoming. The NRC received several requests from interested 

parties to extend the comment period for these documents. The public can use the additional 30 

days to continue reviewing the draft SEIS and provide comments to the NRC regarding review 

of the proposed facilities. 

 The draft reports are the first issued by the agency under its Generic Environmental 

Impact Statement for In-Situ Leach Uranium Milling Facilities (GEIS, NUREG-1910), published 

in June 2009. The GEIS analyzed environmental impacts common to in situ recovery operations 

in four regions of the western United States. The SEIS for each facility incorporates relevant 

discussions and conclusions from the GEIS and examines site-specific impacts unique to that 

proposed facility and its location. All three draft SEIS preliminary recommendations are that, 

unless safety issues mandate otherwise, there are no environmental impacts that would preclude 

granting licenses for the proposed facilities. 

 The three draft SEISs cover license applications for the Moore Ranch Project, proposed 

by Uranium One in Campbell County; the Lost Creek Project, proposed by Lost Creek ISR, 

LLC, for Sweetwater County; and the Nichols Ranch Project, proposed by Uranerz Energy Corp. 

in Campbell and Johnson counties. Each draft SEIS was coordinated with the state of Wyoming, 

the U.S. Environmental Protection Agency, and the U.S. Bureau of Land Management, as well as 

potentially affected Native American tribes near the license applicant facility locations. 

 The GEIS and the individual draft SEIS reports are available on the NRC’s Web site 

through the agency’s online documents database, ADAMS, at the following page: 

http://www.nrc.gov/reading-rm/adams/web-based.html , using accession numbers ML093350050 

for Moore Ranch; ML093350051 for Lost Creek; and ML093340536 for Nichols Ranch. They 

are also available at http://www.nrc.gov/reading-rm/doc-collections/nuregs/staff/sr1910. More
