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.
