This site displays a prototype of a “Web 2.0” version of the daily Federal Register. It is not an official legal edition of the Federal Register, and does not replace the official print version or the official electronic version on GPO’s govinfo.gov.
The documents posted on this site are XML renditions of published Federal Register documents. Each document posted on the site includes a link to the corresponding official PDF file on govinfo.gov. This prototype edition of the daily Federal Register on FederalRegister.gov will remain an unofficial informational resource until the Administrative Committee of the Federal Register (ACFR) issues a regulation granting it official legal status. For complete information about, and access to, our official publications and services, go to About the Federal Register on NARA's archives.gov.
The OFR/GPO partnership is committed to presenting accurate and reliable regulatory information on FederalRegister.gov with the objective of establishing the XML-based Federal Register as an ACFR-sanctioned publication in the future. While every effort has been made to ensure that the material on FederalRegister.gov is accurately displayed, consistent with the official SGML-based PDF version on govinfo.gov, those relying on it for legal research should verify their results against an official edition of the Federal Register. Until the ACFR grants it official status, the XML rendition of the daily Federal Register on FederalRegister.gov does not provide legal notice to the public or judicial notice to the courts.

The U.S. Nuclear Regulatory Commission (NRC) is considering issuing a license amendment to Materials License No. SUA-56, held by Western Nuclear, Inc. (WNI), to authorize revised groundwater protection standards for its facility near Jeffrey City, Wyoming. On June 19, 1981, WNI announced that the facility would be placed on standby because of a diminishing demand for the ore and because of depressed uranium prices. The facility remained on standby until 1986 when the NRC staff amended the license to terminate the use of the tailings impoundments for disposal, and WNI was required to submit a tailings reclamation plan. On December 1, 2008, as supplemented by a February 7, 2009, submittal, WNI submitted a license amendment request for revised groundwater protection standards. On Start Printed Page 6068March 9, 2009, WNI submitted an additional amendment request for groundwater protection standards for other constituents. NRC staff sent a request for additional information on April 1, 2009, which WNI responded to on June 16, 2009. NRC has prepared an Environmental Assessment (EA) in support of this amendment request 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. The amendment will be issued following the publication of this Notice.
II. EA Summary
The purpose of the proposed amendment is to authorize revised groundwater protection standards for the site. Specifically, WNI has requested that an alternate concentration limit (ACL) be set for selenium at the point of compliance wells equal to 0.05 mg/L. This requested selenium value is equal to the U.S. Environmental Protection Agency's (EPA's) maximum contaminant level (MCL) for selenium in drinking water. WNI has also requested that natural uranium trigger levels for licensee action at the point of exposure be set at background levels, specifically 0.087 mg/L for the Split Rock aquifer and 0.044 mg/L for the flood-plain aquifer. The request excludes one well (Well SWAB-32), where the existing standard will not change.
The NRC staff has prepared the EA in support of the proposed license amendment. The NRC staff considered impacts to groundwater, surface water, endangered and threatened species, historic and cultural resources, socioeconomic conditions, and transportation. This EA references previously approved ACLs, which were granted in 2006. The site currently has institutional controls in place limiting the domestic use of groundwater within the proposed long-term surveillance boundary. Because WNI is requesting a standard for selenium values at the points of compliance equal to EPA's MCL and the trigger levels for licensee action at the point of exposure for natural uranium at background levels, the staff does not expect the proposed action to significantly impact the following resource areas: groundwater, surface water, endangered and threatened species, historic and cultural resources, socioeconomic conditions, and transportation.
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 that there is no need to prepare an environmental impact statement.
