I. Introduction

The Nuclear Regulatory Commission (NRC) is issuing an amendment to Materials License No. SUA-1475 issued to Rio Algom Mining, LLC (the licensee), to authorize the consolidating and transporting of materials associated with the lined evaporation ponds at its Ambrosia Lake facility near Grants, NM. NRC has prepared an Environmental Assessment (EA) in support of this amendment in accordance with the requirements of 10 CFR Part 51. Based on the EA, the NRC has concluded that a Finding of No Significant Impact (FONSI) is appropriate. The amendment will be issued following the publication of this Notice.

II. EA Summary

The proposed action is the relocation of the lined evaporation ponds (Section 4 Ponds and Pond 9) at the Ambrosia Lake facility. The action includes the consolidation and removal of byproduct material, transport of the material to the disposal site and disposal of material in accordance with NRC regulations.

In a letter dated November 1, 2004, Rio Algom Mining, LLC (Rio Algom) submitted to the NRC, a Closure Plan-Lined Evaporation Ponds (Relocation Plan) for its Ambrosia Lake uranium mill facility. In a follow-up to the proposed plan, Rio Algom submitted, under letter dated January 28, 2005, a response to a request for additional information and a Revised Relocation Plan. Rio Algom requested that the Revised Relocation Plan be considered initially by NRC so that work can commence at the site. The staff has prepared the EA in support of the proposed license amendment. Staff considered impacts to the land surface, water, air, vegetation, public and worker health and safety, cultural resources, wildlife, and wildlife habitat. The staff found that the potential impacts of the proposed action are limited to the land surface and are temporary due to construction activities. The site Health, Safety and Environment Management System provides adequate assurances to control impacts to the environment. The proposed action will not result in adverse impacts to cultural and historic properties or impact any threatened or endangered species. The overall aesthetics of the area will improve.

III. Finding of No Significant Impact

On the basis of the EA, NRC has concluded that there are no significant environmental impacts from the proposed amendment and has determined not to prepare an environmental impact statement.
