AGENCY:

Nuclear Regulatory Commission.

ACTION:

Notice of availability.

SUMMARY:

Notice is hereby given that the U.S. Nuclear Regulatory Commission (NRC) is issuing a final Supplemental Environmental Impact Statement (SEIS) to the Generic Environmental Impact Statement for In-Situ Leach Uranium Milling Facilities (GEIS), (NUREG-1910, Supplement 3) for the Lost Creek In-Situ Recovery Project in Sweetwater County, Wyoming. By letter dated October 30, 2007, Lost Creek ISR, LLC (LCI), a wholly-owned subsidiary of UR-Energy USA, Inc. submitted an application to the NRC for a new source and byproduct material license for the Lost Creek ISR Project, which LCI proposed to be located in the Great Divide Basin in Sweetwater County, Wyoming. LCI is proposing to recover uranium from the Lost Creek ISR Project site using the in-situ leach (also known as the in-situ recovery [ISR]) process. In this final SEIS, the NRC staff assessed the environmental impacts from the construction, operation, aquifer restoration, and decommissioning of the proposed Lost Creek ISR Project.

In addition to the proposed action, the NRC staff assessed two alternatives in the final SEIS: An alternative that would result in dry yellowcake production at the proposed Lost Creek ISR Project and the No-Action Alternative. In addition, the NRC staff evaluated alternative wastewater disposal options to the proposed action of disposing of liquid effluent via Class I disposal wells. Under the No-Action alternative, NRC would deny LCI's request to construct, operate, conduct aquifer restoration, and decommission an ISR facility at Lost Creek. Alternatives that were considered, but were eliminated from detailed analysis, included conventional mining and milling or heap leach processing. However, given the substantial environmental impact from implementing these alternatives, they were not further considered. The NRC staff also evaluated alternate lixiviants. For reasons discussed in the SEIS, this alternative was also eliminated from detailed analysis.

As discussed in Section 2.4 of the final SEIS, unless safety issues mandate otherwise, the NRC staff's recommendation to the Commission related to the environmental aspects of the proposed action is that the source and byproduct material license be issued as requested. This recommendation is based upon: (1) The license application, including the environmental and technical report submitted by LCI and the applicant's supplemental letters and responses to the NRC staff's requests for additional information; (2) consultation with Federal, State, Tribal, and local agencies; (3) the NRC staff's independent review; (4) the NRC staff's consideration of comments received on the draft SEIS; and (5) the assessments summarized in this SEIS.

The final SEIS for the Lost Creek ISR Project may be accessed on the Internet at http://www.nrc.gov/​reading-rm/​doc-collections/​nuregs/​staff/​sr1910/​s3/​. Additionally, the NRC maintains an Agencywide Documents and Management System (ADAMS), which Start Printed Page 37161provides text and image files of the NRC's public documents. The SEIS may also be accessed online at NRC's Library at: http://www.nrc.gov/​reading-rm/​adams.html.
