SUPPLEMENTARY INFORMATION:

I. Introduction

The U.S. Nuclear Regulatory Commission (NRC) plans to issue a license amendment to Source Materials License No. SUA-56 held by Western Nuclear, Inc. (the Licensee), to authorize the establishment of alternate concentration limits (ACLs) at its Split Rock uranium mill tailings site in Jeffrey City, Wyoming. The NRC has prepared an Environmental Assessment (EA) in support of the proposed action 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 is appropriate. Final action on the Licensee's amendment request will be taken following publication of this notice. The NRC will issue a technical evaluation report addressing the safety aspects of establishing ACLs at the Licensee's facility.

II. EA Summary

The purpose of the proposed amendment is to authorize the establishment of ACLs instead of ground water protection standards for six constituents at the Licensee's Jeffrey City, Wyoming, facility. Specifically, this amendment will establish ACLs for ammonia, manganese, molybdenum, nitrate, radium-226 and -228, and natural uranium. This amendment will also require the Licensee to establish institutional controls on all properties within the long-term surveillance boundary to preclude domestic ground water use. On October 29, 1999, the Licensee requested that NRC approve the proposed amendment.

The staff has prepared the EA in support of the proposed license amendment. The staff considered impacts to ground water, surface water, land use, ecology, socioeconomic conditions, and historical and cultural resources. Impacts to ground water are mitigated by the use of institutional controls that prevent human consumption of contaminated ground water within the long-term surveillance boundary. However, agricultural and livestock uses have been preserved within the long-term surveillance boundary. A surface water and ground water monitoring program has been established to track ground water contamination, and trigger levels for surface water and ground water have been established, the exceedance of which would require a response from the Licensee.

III. Finding of No Significant Impact

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