Notice of issuance of materials license SUA-1598.

End Preamble Start Supplemental Information


The U.S. Nuclear Regulatory Commission (NRC or the Commission) has issued a license to Lost Creek ISR, LLC (LCI) for its Lost Creek uranium in-situ recovery (ISR) project in Sweetwater County, Wyoming. Materials License SUA-1598 authorizes LCI to operate its facilities as proposed in its license application, as amended, and to possess uranium source and byproduct material at the Lost Creek Project. Furthermore, LCI will be required to operate under the conditions listed in Materials License SUA-1598.

This notice also serves as the record of decision for the NRC decision to approve LCI's license application for the Lost Creek Project and to issue Materials License SUA-1598. This record of decision satisfies the regulatory requirement in Section 51.102(a) of Title 10 of the Code of Federal Regulations (10 CFR), which requires a Commission decision on any action for which a final environmental impact statement has been prepared to be accompanied by or to include a concise public record of decision.

The NRC considers the entire publicly available record for a license application to constitute the agency's record of decision. Documents related to this application carry Docket Number 04009068. You can access the NRC's Agencywide Documents Access and Management System (ADAMS), which provides text and image files of the NRC's public documents in the NRC Library at​reading-rm/​adams.html. These documents for the Lost Creek Project include the license application (including the applicant's environmental report) [ADAMS Accession No. ML081060502], the Commission's Safety Evaluation Report (SER) published in August 2011 [ADAMS Accession No. ML112231724], and the Commission's Final Supplemental Environmental Impact Statement (FSEIS) (NUREG-1910, Supplement 3) published in June 2011 [ADAMS Accession No. ML11125A006]. The record of decision also includes the applicable portions of the Generic Environmental Impact Statement for In-Situ Leach Uranium Milling Facilities (NUREG-1910), as incorporated by reference in the FSEIS.

As discussed in the Lost Creek FSEIS, the Commission considered a range of alternatives. The reasonable alternatives discussed in detail were the applicant's proposal as described in its license application to conduct in-situ uranium recovery on the site, the no-action alternative, and the dry yellowcake alternative. Under the proposed action, yellowcake slurry would be produced, but not dried, onsite, whereas the dry yellowcake alternative considered the impacts of installing a dryer onsite to produce dry yellowcake from the yellowcake slurry produced onsite. Before a dryer could be installed on the Lost Creek Project site, the licensee would be required to submit a license amendment request, and the NRC would need to approve such a request. Other alternatives considered, but eliminated from detailed analysis, include conventional uranium mining and milling, conventional mining and heap leach processing, alternate lixiviants, and alternative wastewater disposal options. The Lost Creek FSEIS also discussed the factors considered when evaluating the alternatives, a comparison among the alternatives, and license conditions and monitoring programs. The FSEIS also contained the NRC staff recommendation to the Commission, related to the environmental aspects of the proposed action that the source material license should be issued as requested, unless safety issues mandate otherwise.Start Printed Page 53501

The NRC has found that the application for the source materials license complied with the standards and requirements of the Atomic Energy Act of 1954, as amended (the Act), and the Commission's regulations. As required by the Act and the Commission's regulations in 10 CFR 40.32(b)-(c), the staff has found that LCI is qualified by reason of training and experience to use source material for the purpose that it requested, and that LCI's proposed equipment and procedures for use at its Lost Creek Project are adequate to protect public health and minimize danger to life or property. The NRC staff's review supporting these findings is documented in the SER. The NRC staff also concluded, in accordance with 10 CFR 40.32(d), that issuance of Materials License SUA-1598 to LCI will not be inimical to the common defense and security or to the health and safety of the public. The staff also found in accordance with 10 CFR 40.32(e), after weighing the environmental, economic, technical, and other benefits against environmental costs and considering available alternatives, that the appropriate action is to issue Materials License SUA-1598.

LCI's request for a materials license was previously noticed in the Federal Register on July 10, 2008 (73 FR 39728), with a notice of an opportunity to request a hearing. The NRC did not receive any requests for a hearing on the license application.
