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.

IV. Further Information

amendment, the EA, and other supporting documentation, are available
