Public Workshop to Discuss Low-Level Radioactive Waste Management
The U.S. Nuclear Regulatory Commission (NRC), in coordination with the U.S. Department of Energy (DOE), plans to conduct a workshop to discuss possible approaches to revising the regulatory framework for the management of commercial low-level radioactive waste (LLW). The purpose of this workshop is to gather information from a broad spectrum of stakeholders concerning the NRC's proposed options for a comprehensive revision to NRC's and DOE's waste regulations and to discuss possible options.
Dan Kane; Denial of Petition for Rulemaking
The Nuclear Regulatory Commission (NRC) is denying a petition for rulemaking (PRM) submitted by Dan Kane. Mr. Kane requested that the NRC rescind the Waste Confidence Rule, suspend all ongoing reactor licensing proceedings, and phase out operations at all operating nuclear power plants. The NRC is denying the petition because, contrary to the assertions made in the PRM, the Commission's Waste Confidence Decision and Rule consider the political uncertainty discussed in the petition and do not depend on the availability of a repository at Yucca Mountain, Nevada.
Amendments to Adjudicatory Process Rules and Related Requirements
The U.S. Nuclear Regulatory Commission (NRC or the Commission) is proposing to amend its adjudicatory rules of practice. This proposed rule would make changes to the NRC's adjudicatory process that NRC believes will promote fairness, efficiency, and openness in NRC adjudicatory proceedings. This proposed rule would also correct errors and omissions that have been identified since the major revisions to the NRC's Rules of Practice in early 2004.
AP1000 Design Certification Amendment
The U.S. Nuclear Regulatory Commission (NRC or Commission) proposes to amend its regulations to certify an amendment to the AP1000 standard plant design. The purpose of the amendment is to replace the combined license (COL) information items and design acceptance criteria (DAC) with specific design information, address the effects of the impact of a large commercial aircraft, incorporate design improvements, and increase standardization of the design. Upon NRC rulemaking approval of its amendment to the AP1000 design, an applicant seeking an NRC license to construct and operate a nuclear power reactor using the AP1000 design need not demonstrate in its application the safety of the certified design. The applicant for this amendment to the AP1000 certified design is Westinghouse Electric Company, LLC (Westinghouse). The public is invited to submit comments on this proposed design certification rule (DCR), the revised generic design control document (DCD) that would be incorporated by reference into the DCR, and the environmental assessment (EA) for this amendment to the AP1000 design.

Notice of Availability of Final Environmental Impact Statement for the AREVA Enrichment Services LLC Proposed Eagle Rock Enrichment Facility in Bonneville County, ID
Notice is hereby given that the U.S. Nuclear Regulatory Commission (NRC) has published the Final Environmental Impact Statement (EIS) for the AREVA Enrichment Services LLC (AES) Proposed Eagle Rock Enrichment Facility (EREF). On December 30, 2008, AES submitted a license application to the NRC that proposes the construction, operation, and decommissioning of a gas centrifuge-based uranium enrichment facility on a presently undeveloped site near Idaho Falls in Bonneville County, Idaho (the ``proposed action''). This application is for a license to possess and use byproduct material, source material, and special nuclear material at the proposed uranium enrichment facility. The application included an Environmental Report (ER) regarding the proposed action. AES subsequently submitted revisions to the license application on April 23, 2009 (Revision 1), and April 30, 2010 (Revision 2), which included ER Revision 1 and ER Revision 2, respectively. License application Revision 1 addresses the expansion of the proposed EREF to increase its production capacity from 3.3 million Separative Work Units (SWUs) per year to 6.6 million SWUs per year; and ER Revision 1 includes information on the environmental impacts of the proposed 6.6- million-SWU-per-year EREF. Revision 2 to the license application and the ER incorporates into Revision 1 additional information that AES previously provided the NRC in response to NRC staff requests for additional information for its safety and environmental reviews, as well as supplemental information on a proposed electrical transmission line required to power the proposed EREF. On June 17, 2009, AES submitted a request for an exemption from certain NRC regulations so that it could commence certain preconstruction activities (e.g., site preparation) on the proposed EREF site prior to the NRC's decision on whether to grant or deny a license. On March 17, 2010, the NRC granted an exemption authorizing AES to conduct the requested preconstruction activities. The Final EIS is being issued as part of the NRC's process to decide whether to issue a license to AES, pursuant to Title 10 of the Code of Federal Regulations (10 CFR) parts 30, 40, and 70, to construct and operate the proposed uranium enrichment facility. Specifically, AES proposes to use gas centrifuge technology to enrich the uranium-235 isotope found in natural uranium to concentrations up to 5 percent by weight. The enriched uranium would be used to manufacture nuclear fuel for commercial nuclear power reactors. In the Final EIS, the NRC staff assessed the potential environmental impacts from the preconstruction, construction, operation, and decommissioning of the proposed EREF project. The Final EIS was prepared in compliance with the National Environmental Policy Act of 1969, as amended (NEPA), and the NRC's regulations for implementing NEPA in 10 CFR part 51. The NRC staff assessed the impacts of the proposed action on land use, historic and cultural resources, visual and scenic resources, air quality, geology and soils, water resources, ecological resources, noise, transportation, public and occupational health, waste management, socioeconomics, and environmental justice. Additionally, the NRC staff analyzed and compared the benefits and costs of the proposed action. In preparing this Final EIS, the NRC staff also reviewed, considered, evaluated, and addressed the public comments received on the Draft EIS. In addition to the proposed action, the NRC staff considered the no-action alternative and other alternatives. Under the no-action alternative, the NRC would deny AES's request to construct and operate a uranium enrichment facility at the EREF site. The no-action alternative serves as a baseline for comparison of the potential environmental impacts of the proposed action. Other alternatives the NRC staff considered but eliminated from further analysis include: (1) Alternative sites for the EREF; (2) alternative sources of enriched uranium; and (3) alternative technologies for uranium enrichment. These alternatives were eliminated from further analysis due to economic, environmental, national security, technological maturity, or other reasons. The Final EIS also discusses alternatives for the disposition of depleted uranium hexafluoride (UF6) resulting from enrichment operations over the lifetime of the proposed EREF. After weighing the impacts, costs, and benefits of the proposed action and comparing alternatives, the NRC staff, in accordance with 10 CFR 51.91(d), sets forth its recommendation regarding the proposed action. The NRC staff recommends that, unless safety issues mandate otherwise, the proposed action should be approved (i.e., NRC should issue a license). In this regard, the NRC staff has concluded that the environmental impacts of the proposed action are generally small, and that implementation of the proposed AES environmental monitoring program and AES mitigation measures discussed in the Final EIS would eliminate or substantially lessen any adverse environmental impacts associated with the proposed action. Document Availability: The Final EIS and other publicly available documents related to this notice can be accessed using any of the methods described in this section. Because one appendix of the Final EIS contains Sensitive Unclassified Non-Safeguards Information (SUNSI), this appendix has been withheld from public inspection in accordance with 10 CFR 2.390, ``Availability of Public Records.'' This appendix contains proprietary business information as well as security-related information. The NRC staff has considered the information in this appendix in forming the conclusions presented in the EIS.

Office of New Reactors; Proposed Revision 1 to Standard Review Plan, Section 188.8.131.52 on Administrative Procedures-General
The NRC is soliciting public comment on NUREG-0800, ``Standard Review Plan for the Review of Safety Analysis Reports for Nuclear Power Plants,'' on a proposed Revision 1 to Standard Review Plan (SRP), Section 184.108.40.206 on ``Administrative ProceduresGeneral,'' (Agencywide Documents Access and Management System (ADAMS) Accession No. ML110100193). The previous version of this SRP section was published in July 19, 2010, as proposed revision 1 (ADAMS Accession No. ML101340264). Since then, the NRC staff has made substantial changes to that guidance and it is being re-noticed for comments (Enclosure 1, ADAMS Accession No. ML110100212). A redline document comparing the version of the previous SRP Section 220.127.116.11, Revision 1 that was issued for public comments and the current version can be found under ADAMS Accession No. ML101340165. The NRC staff issues notices to facilitate timely implementation of the current staff guidance and to facilitate activities associated with the review of amendment applications and review of design certification and combined license applications for the Office of New Reactors. The NRC staff intends to incorporate the final approved guidance into the next revision of NUREG-0800, SRP Section 18.104.22.168, Revision 1 and Regulatory Guide 1.206, ``Combined License Applications for Nuclear Power Plants (LWR Edition),'' June 2007.
Agency Information Collection Activities: Submission for the Office of Management and Budget (OMB) Review; Comment Request
The NRC has recently submitted to OMB for review the following proposal for the collection of information under the provisions of the Paperwork Reduction Act of 1995 (44 U.S.C. Chapter 35). The NRC hereby informs potential respondents that an agency may not conduct or sponsor, and that a person is not required to respond to, a collection of information unless it displays a currently valid OMB control number. The NRC published a Federal Register Notice with a 60-day comment period on this information collection on November 22, 2010. 1. Type of submission, new, revision, or extension: Revision. 2. The title of the information collection: Comprehensive Decommissioning Program, Including Annual Data Collection. 3. Current OMB approval number: 3150-0206. 4. The form number if applicable: N/A. 5. How often the collection is required: Annually. 6. Who will be required or asked to report: All Agreement States who have signed Section 274(b) Agreements with NRC. 7. An estimate of the number of annual responses: 83. 8. The estimated number of annual respondents: 37 (13 Agreement States respondents with sites of interest + 24 Agreement States respondents with no sites of interest). 9. An estimate of the total number of hours needed annually to complete the requirement or request: 662 (590 hours from Agreement States with sites of interest + 72 hours from Agreement States with no sites of interest). 10. Abstract: Agreement States will be asked to provide information about uranium recovery and complex sites undergoing decommissioning regulated by the Agreement States on an annual basis. The information request will allow the NRC to compile, in a centralized location, more complete information on the status of decommissioning and decontamination in the United States in order to provide a national perspective on decommissioning. The information will be made available to the public by the NRC in order to ensure openness and promote communication to enhance public knowledge of the national decommissioning program. This does not apply to information, such as trade secrets and commercial or financial information provided by the Agreement States, that is considered privileged or confidential. Information such as financial assurance and the status of decommissioning funding would need to be identified by the Agreement State as privileged or confidential, whereupon the NRC would withhold such information from public access and treat it as sensitive or non- sensitive, per the considerations in 10 CFR 2.390 and 9.17. This does not apply to financial assurance or decommissioning funding information that is already available to the public. Although specific details of the funding mechanisms are treated as confidential, beneficial lessons learned regarding the improvement of decommissioning-related funding will be shared with the Agreement States. A copy of the final supporting statement may be viewed free of charge at the NRC Public Document Room, One White Flint North, 11555 Rockville Pike, Room O-1 F21, Rockville, Maryland 20852. OMB clearance requests are available at the NRC worldwide Web site: http:// www.nrc.gov/public-involve/doc-comment/omb/index.html. The document will be available on the NRC home page site for 60 days after the signature date of this notice. Comments and questions should be directed to the OMB reviewer listed below by March 10, 2011. Comments received after this date will be considered if it is practical to do so, but assurance of consideration cannot be given to comments received after this date. Christine J. Kymn, Desk Officer, Office of Information and Regulatory Affairs (3150-0206), NEOB-10202, Office of Management and Budget, Washington, DC 20503.

Draft Regulatory Guide: Issuance, Availability
The U.S. Nuclear Regulatory Commission (Commission or NRC) is issuing for public comment Draft Regulatory Guide, DG-5020, ``Applying for Enhanced Weapons Authority, Applying for Preemption Authority, and Accomplishing Firearms Background Checks under 10 CFR Part 73.'' The DG-5020 is a proposed new regulatory guide. This guide describes methods that the staff or NRC considers acceptable for licensees and certificate holders to comply with the Commission's regulations implementing the provisions of Section 161A, ``Use of Firearms by Security Personnel,'' of the Atomic Energy Act of 1954, as amended (42 U.S.C. 2201a), that are found in the proposed Title 10 of the Code of Federal Regulations (10 CFR) 73.18, ``Authorization for use of Enhanced Weapons and Preemption of Firearms Laws,'' and 10 CFR 73.19, ``Firearms Background Checks for Armed Security Personnel.''
Draft Weapons Safety Assessment on the Use of Enhanced Weapons; Notice of Availability and Request for Comment
The U.S. Nuclear Regulatory Commission (Commission or NRC) is seeking input from the public, licensees, certificate holders, and other stakeholders on a draft guidance document entitled ``Weapons Safety Assessment'' (WSA). This guidance would be used by licensees and certificate holders applying to the NRC to obtain enhanced weapons under the NRC's proposed rule titled ``Enhanced Weapons, Firearms Background Checks, and Security Event Notifications,'' published in the Proposed Rule section of today's Federal Register (NRC-2011-0018). A completed WSA would be part of an application to the NRC for the use for enhanced weapons. The Commission is authorized under Section 161A of the Atomic Energy Act of 1954, as amended (AEA), to approve licensees' and certificate holders' possession of enhanced weapons as part of a protective strategy for defending NRC-regulated facilities and radioactive material against malevolent acts. Volumes 1 through 3 of the draft WSA are being issued for public review and comment.
Draft Regulatory Guide: Issuance, Availability
The U.S. Nuclear Regulatory Commission (Commission or NRC) is issuing for public comment Draft Regulatory Guide, DG-5019, ``Reporting and Recording Safeguards Events.'' The DG-5019 describes methods that the staff of the NRC considers acceptable for licensees and certificate holders to report and record safeguards (i.e., security) events that are required under the proposed changes to Title 10 of the Code of Federal Regulations (10 CFR) 73.71, ``Reporting and Recording of Safeguards Events,'' and Appendix G to 10 CFR part 73, ``Reportable and Recordable Safeguards Events.''
Enhanced Weapons, Firearms Background Checks, and Security Event Notifications
The Nuclear Regulatory Commission (NRC or the Commission) is proposing regulations that would implement its authority under the new section 161A of the Atomic Energy Act of 1954 (AEA), as amended, and revise existing regulations governing security event notifications. These proposed regulations are consistent with the provisions of the Firearms Guidelines the NRC published under section 161A with the approval of the U.S. Attorney General on September 11, 2009 (74 FR 46800). The NRC previously proposed new regulations on October 26, 2006 (71 FR 62663), that would have implemented this new authority as part of a larger proposed rule entitled ``Power Reactor Security Requirements.'' However, based upon changes to the final Firearms Guidelines the NRC is now proposing further revisions in these implementing regulations that address the voluntary application for enhanced weapons and the mandatory firearms background checks under section 161A. These implementing regulations would only apply to nuclear power reactor facilities and Category I strategic special nuclear material (SSNM) facilities. In addition, the NRC is also proposing revisions addressing security event notifications from different classes of facilities and the transportation of radioactive material consistently and would add new event notification requirements on the theft or loss of enhanced weapons.
