UMETCO Minerals Corp.; Final Finding of No Significant Impact; Notice of Opportunity for Hearing

요약

The Umetco Minerals Corporation (Umetco) requested that the U.S. Nuclear Regulatory Commission (NRC) amend its NRC Source Material License SUA-648 to authorize reclamation of the A-9 Repository (disposal cell), located in Natrona County, Wyoming, according to the 1998 Enhanced Reclamation Plan, as amended. The Umetco East Gas Hills site is located approximately 50 miles (80 kilometers) southeast of the town of Riverton, Wyoming. The A-9 cell is a former surface uranium mine that was lined with clay and used for mill tailings disposal. Cover construction was begun under a previously approved reclamation design and several changes have been proposed in the enhanced plan. An Environmental Assessment (EA) was performed by the NRC staff in support of its review of Umetco's license amendment request, in accordance with the requirements of 10 CFR part 51. The conclusion of the EA is a Finding of No Significant Impact (FONSI) for the proposed licensing action.
