I. Introduction

    The Nuclear Regulatory Commission (NRC) is issuing an amendment to 
Materials License No. SUA-442, issued to Pathfinder Mines Corporation 
(the licensee), to authorize alternate concentration limits (ACLs) at 
its Shirley Basin site in Carbon County, WY. 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 purpose of the proposed amendment is to authorize ACLs for 
chloride, radium-226 + -228, selenium, sulfate, thorium-230, total 
dissolved solids (TDS), and uranium at the licensee's Shirley Basin 
site. Specifically, the amendment will replace current ground-water 
protection standards with ACLs because reducing ground-water 
concentrations to meet current standards is not feasible using the 
current ground-water corrective action program (CAP). The Licensee will 
also deactivate the current CAP because approval of the ACLs will bring 
all ground-water constituents of concern into compliance with approved 
standards. The current CAP has significantly reduced concentrations of 
the aforementioned constituents in ground water to the extent that 
deactivating the CAP is not expected to impact human health, safety, 
and the environment.
    On April 3, 2000, Pathfinder Mines Corporation requested that NRC 
approve the proposed amendment. The staff has prepared the EA in 
support of the proposed license amendment. Staff considered impacts to 
land use, geology and soils, water resources, ecology, meteorology, 
climatology, air quality, socioeconomics, historical and cultural 
resources, public and occupational health, and transportation. The 
staff found that the impacts of the proposed action were not 
significant because ground-water remedial actions have significantly 
reduced the areal extent and concentration of hazardous constituents, 
and considerable modeling and ground-water sampling have adequately 
demonstrated that residual groundwater constituent concentrations are 
not expected to impact human health, safety, and the environment.

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.
