SUPPLEMENTARY INFORMATION: Title of Collection: Antarctic emergency response plan and environmental protection information. OMB Approval Number: 3145–0180. Abstract: The NSF, pursuant to the Antarctic Conservation Act of 1978 (16 U.S.C. 2401 et seq.) (‘‘ACA’’) regulates certain non-governmental activities in Antarctica. The ACA was amended in 1996 by the Antarctic Science, Tourism, and Conservation Act. On September 7, 2001, NSF published a final rule in the Federal Register (66 FR 46739) implementing certain of these statutory amendments. The rule requires nongovernmental Antarctic expeditions using non-U.S. flagged vessels to ensure that the vessel owner has an emergency response plan. The rule also requires persons organizing a non-governmental expedition to provide expedition members with information on their environmental protection obligations under the Antarctic Conservation Act. Expected Respondents. Respondents may include non-profit organizations and small and large businesses. The majority of respondents are anticipated to be U.S. tour operators, currently estimated to number twelve. Burden on the Public. The Foundation estimates that a one-time paperwork and recordkeeping burden of 40 hours or less, at a cost of $500 to $1400 per respondent, will result from the emergency response plan requirement contained in the rule. Presently, all respondents have been providing expedition members with a copy of the Guidance for Visitors to the Antarctic (prepared and adopted at the Eighteenth Antarctic Treaty Consultative Meeting as Recommendation XVIII–1). Because this Antarctic Treaty System document satisfies the environmental protection information requirements of the rule, no additional burden shall result from the environmental information requirements in the proposed rule. srobinson on DSKHWCL6B1PROD with NOTICES ADDRESSES: VerDate Mar<15>2010 16:17 Jun 21, 2010 Jkt 220001 Dated: June 17, 2010.

Introduction The U.S. Nuclear Regulatory Commission (NRC) is issuing for public comment a draft guide in the agency’s ‘‘Regulatory Guide’’ series. This series was developed to describe and make available to the public such information as methods that are acceptable to the NRC staff for implementing specific parts of the NRC’s regulations, techniques that the staff uses in evaluating specific problems or postulated accidents, and data that the staff needs in its review of applications for permits and licenses. The draft regulatory guide (DG) is temporarily identified with its task number, DG–1249, which should be mentioned in all related correspondence. DG–1249 is proposed Revision 3 of Regulatory Guide 1.152, dated January 2006. This guide describes a method that the staff of the NRC considers acceptable to implement Title 10, of the Code of Federal Regulations, Part 50, ‘‘Domestic Licensing of Production and Utilization Facilities’’ (10 CFR Part 50); 10 CFR 50.55a(h); General Design Criterion (GDC) 21, ‘‘Protection System Reliability and Testability,’’ of Appendix A, ‘‘General Design Criteria for Nuclear Power Plants,’’ to 10 CFR Part 50; and Criterion III, ‘‘Design Control,’’ of Appendix B, ‘‘Quality Assurance Criteria for Nuclear Power Plants and Fuel Reprocessing Plants,’’ to 10 CFR Part 50 with regard to use of computers in safety systems of nuclear power plants. This guide applies to all types of commercial nuclear power plants. DG–1249 acknowledges that 10 CFR 73.54, ‘‘Protection of Digital Computer and Communication Systems and Networks,’’ requires licensees to develop cyber-security plans and programs to protect critical digital assets, including digital safety systems, from malicious cyber attacks. Regulatory Guide 5.71, ‘‘Cyber Security Programs for Nuclear Facilities,’’ provides guidance to meet the requirements of 10 CFR 73.54. The combination of DG–1249 and the programmatic provisions under 10 CFR 73.54 should seamlessly address the secure design, development, and operation of digital safety systems. To seamlessly address these issues, DG– 1249: 1. Eliminates all reference to cyber security, malicious activity, or attacks, as those considerations now fall under the purview of 10 CFR 73.54. Since there is now a regulation and associated guidance specifically designed to address cyber security, Regulatory Guide 1.152 no longer needs to address VerDate Mar<15>2010 16:17 Jun 21, 2010 Jkt 220001 cyber security. To eliminate any duplication between the documents, references to cyber security and any protection against a malicious, intelligent adversary have been removed. 2. Emphasizes Regulatory Guide 1.152’s focus on security for the protection of digital safety systems against non-malicious events, per Clauses 5.6.3 and 5.9 of the Institute of Electrical and Electronic Engineer (IEEE) standard 603–1991. Nonmalicious events include incidents in which an operator or other plant personnel could inadvertently access the digital safety system and affect its ability to reliably perform its safety function. Non-malicious events also include undesirable behavior of connected systems which could degrade the reliable operation of the digital safety system. 3. Deletes Regulatory Positions 2.6 through 2.9, which address security in the operational phases of a system’s life cycle. Licensing is complete once the Factory Acceptance Testing is concluded. The licensee’s cyber security programs, to meet the requirements of 10 CFR 73.54, should now address these considerations. (Regulatory Positions 2.1 through 2.5 apply to licensing determinations in the evaluation of applications for license amendments, design certifications, and combined operating licenses.) ‘‘Security,’’ in the context of DG–1249, refers to protective actions taken against a predictable set of non-malicious acts (e.g., inadvertent operator actions or the undesirable behavior of connected systems) that could challenge the integrity, reliability, or functionality of a digital safety system. ‘‘Cyber security’’ refers to those measures and controls taken as part of compliance with 10 CFR 73.54 that protect digital systems against the malicious acts of an intelligent adversary. The objective of this revision is to (1) clarify the relationship between 10 CFR Part 50 and 10 CFR Part 73, ‘‘Physical Protection of Plants and Materials,’’ regarding the security of digital safety systems, (2) remove regulatory positions that are now covered by other regulations to eliminate the potential for any perceived conflict, and (3) to clarify the remaining regulatory positions. The NRC staff is revising Regulatory Guide 1.152 to provide what the staff considers to be an acceptable method of meeting the NRC regulations. Previous revisions should not be used by applicants for new licensing actions. NRC staff believes that continued use of previous revisions of the Regulatory PO 00000 Frm 00073 Fmt 4703 Sfmt 4703 35509 Guide by existing nuclear power plant licensees is acceptable (i.e., meets all NRC requirements, and provides reasonable assurance of adequate protection to public health and safety, and common defense and security). Revision of this Regulatory Guide does not modify any prior commitments made by licensees to the NRC or Agreement States. Therefore, a licensee that has made a commitment must continue to meet that prior commitment, or the commitment should be modified in accordance with the licensee’s commitment management process. The previous revision of this Regulatory Guide will continue to be publically available on the NRC public Web site. II. Further Information The NRC staff is soliciting comments on DG–1249. Comments may be accompanied by relevant information or supporting data and should mention DG–1249 in the subject line. Comments submitted in writing or in electronic form will be made available to the public in their entirety through the NRC’s Agencywide Documents Access and Management System (ADAMS).

ACTION: Notice of availability. SUMMARY: The NRC is issuing a revision to its license renewal interim staff guidance (LR–ISG) process. This revision is entitled, ‘‘License Renewal Interim Staff Guidance Process, Revision 2’’ (revised LR–ISG process). The LR–ISG process describes the basic framework for developing and implementing interim changes to certain NRC license renewal guidance documents. These guidance documents facilitate the implementation of and NRC staff review of license renewal applications submitted in accordance with Title 10 of the Code of Federal Regulations (10 CFR) Part 54, ‘‘Requirements for Renewal of Operating Licenses for Nuclear Power Plants,’’ and Part 51, ‘‘Environmental Protection Regulations for Domestic Licensing and Related Regulatory Functions.’’ An electronic copy of the revised LR–ISG process is available in the NRC’s Agencywide Documents Access and Management System (ADAMS) under Accession No. ML100920158. The revised LR–ISG process supersedes the document entitled, ‘‘License Renewal Interim Staff Guidance Process, Revision 1’’ (ML091950069) (the previous LR–ISG process). FOR FURTHER INFORMATION CONTACT: Mr. Matthew Homiack, Division of License Renewal, Office of Nuclear Reactor Regulation, U.S. Nuclear Regulatory Commission, Washington, DC 20555– 0001; telephone 301–415–1683; or email Matthew.Homiack@nrc.gov. ADDRESSES: Documents created or received after November 1, 1999, are available electronically at the NRC’s Public Electronic Reading Room on the Internet at http://www.nrc.gov/readingrm/adams.html. From this site, the public can gain entry into ADAMS. If you do not have access to the Internet or if there are any problems in accessing the documents located in ADAMS, contact the NRC Public Document Room reference staff at 1–800–397–4209, 301– 415–4737, or by e-mail at PDR.Resource@nrc.gov. The NRC posts LR–ISGs and the LR– ISG process on its public Web page under the ‘‘License Renewal’’ heading at http://www.nrc.gov/reading-rm/doccollections/isg. PO 00000 Frm 00074 Fmt 4703 Sfmt 9990 Background The NRC issued the previous LR–ISG process on August 7, 2009, and a notice of availability was published in the Federal Register on August 17, 2009 (74 FR 41461). In this previous process, the NRC staff addressed a recommendation from the NRC’s Office of the Inspector General (OIG) report, OIG–07–A–15, ‘‘Audit of the NRC’s License Renewal Program,’’ dated September 6, 2007 (ML072490486). Accordingly, enhancements were made to the LR–ISG process for the NRC staff to evaluate and document its determinations as to whether LR–ISGs meet the provisions of 10 CFR 54.37(b) and 10 CFR 50.109. As part of this evaluation, the previous LR– ISG process references a draft version of NRC Regulatory Issue Summary (RIS) 2007–16, Revision 1, ‘‘Implementation of the Requirements of 10 CFR 54.37(b) for Holders of Renewed Licenses.’’ At the time the previous process was issued, the NRC staff had not issued the final RIS 2007–16, Revision 1. After issuance of the previous LR–ISG process, the NRC staff identified the need to make some additional clarifications and administrative changes to the process. The clarifications concern the staff’s evaluation of LR–ISGs under 10 CFR 54.37(b) and 10 CFR 50.109 and the applicability of LR–ISGs to renewed license holders. The administrative changes include reference to the final RIS 2007–16, Revision 1, which the NRC issued on April 28, 2010 (ML100250279), and minor changes to the format and content of LR–ISG documents. The NRC staff incorporated these changes into the revised LR–ISG process, which was issued on June 14, 2010. The NRC did not publish a request for public comment in the Federal Register because of the administrative scope of the changes and clarifications. Final Action By this action, the NRC is notifying the public of issuance of the revised LR– ISG process. As of June 14, 2010, the NRC staff will use this process to guide the development and implementation of LR–ISGs. Dated at Rockville, Maryland, this 14th day of June 2010.

SUPPLEMENTARY INFORMATION:

I. Introduction

    The U.S. Nuclear Regulatory Commission (NRC) is issuing for public 
comment a draft guide in the agency's ``Regulatory Guide'' series. This 
series was developed to describe and make available to the public such 
information as methods that are acceptable to the NRC staff for 
implementing specific parts of the NRC's regulations, techniques that 
the staff uses in evaluating specific problems or postulated accidents, 
and data that the staff needs in its review of applications for permits 
and licenses.
    The draft regulatory guide (DG) is temporarily identified with its 
task number, DG-1249, which should be mentioned in all related 
correspondence. DG-1249 is proposed Revision 3 of Regulatory Guide 
1.152, dated January 2006. This guide describes a method that the staff 
of the NRC considers acceptable to implement Title 10, of the Code of 
Federal Regulations, Part 50, ``Domestic Licensing of Production and 
Utilization Facilities'' (10 CFR Part 50); 10 CFR 50.55a(h); General 
Design Criterion (GDC) 21, ``Protection System Reliability and 
Testability,'' of Appendix A, ``General Design Criteria for Nuclear 
Power Plants,'' to 10 CFR Part 50; and Criterion III, ``Design 
Control,'' of Appendix B, ``Quality Assurance Criteria for Nuclear 
Power Plants and Fuel Reprocessing Plants,'' to 10 CFR Part 50 with 
regard to use of computers in safety systems of nuclear power plants. 
This guide applies to all types of commercial nuclear power plants.
    DG-1249 acknowledges that 10 CFR 73.54, ``Protection of Digital 
Computer and Communication Systems and Networks,'' requires licensees 
to develop cyber-security plans and programs to protect critical 
digital assets, including digital safety systems, from malicious cyber 
attacks. Regulatory Guide 5.71, ``Cyber Security Programs for Nuclear 
Facilities,'' provides guidance to meet the requirements of 10 CFR 
73.54. The combination of DG-1249 and the programmatic provisions under 
10 CFR 73.54 should seamlessly address the secure design, development, 
and operation of digital safety systems. To seamlessly address these 
issues, DG-1249:
    1. Eliminates all reference to cyber security, malicious activity, 
or attacks, as those considerations now fall under the purview of 10 
CFR 73.54. Since there is now a regulation and associated guidance 
specifically designed to address cyber security, Regulatory Guide 1.152 
no longer needs to address cyber security. To eliminate any duplication 
between the documents, references to cyber security and any protection 
against a malicious, intelligent adversary have been removed.
    2. Emphasizes Regulatory Guide 1.152's focus on security for the 
protection of digital safety systems against non-malicious events, per 
Clauses 5.6.3 and 5.9 of the Institute of Electrical and Electronic 
Engineer (IEEE) standard 603-1991. Non-malicious events include 
incidents in which an operator or other plant personnel could 
inadvertently access the digital safety system and affect its ability 
to reliably perform its safety function. Non-malicious events also 
include undesirable behavior of connected systems which could degrade 
the reliable operation of the digital safety system.
    3. Deletes Regulatory Positions 2.6 through 2.9, which address 
security in the operational phases of a system's life cycle. Licensing 
is complete once the Factory Acceptance Testing is concluded. The 
licensee's cyber security programs, to meet the requirements of 10 CFR 
73.54, should now address these considerations. (Regulatory Positions 
2.1 through 2.5 apply to licensing determinations in the evaluation of 
applications for license amendments, design certifications, and 
combined operating licenses.)
    ``Security,'' in the context of DG-1249, refers to protective 
actions taken against a predictable set of non-malicious acts (e.g., 
inadvertent operator actions or the undesirable behavior of connected 
systems) that could challenge the integrity, reliability, or 
functionality of a digital safety system.
    ``Cyber security'' refers to those measures and controls taken as 
part of compliance with 10 CFR 73.54 that protect digital systems 
against the malicious acts of an intelligent adversary.
    The objective of this revision is to (1) clarify the relationship 
between 10 CFR Part 50 and 10 CFR Part 73, ``Physical Protection of 
Plants and Materials,'' regarding the security of digital safety 
systems, (2) remove regulatory positions that are now covered by other 
regulations to eliminate the potential for any perceived conflict, and 
(3) to clarify the remaining regulatory positions.
    The NRC staff is revising Regulatory Guide 1.152 to provide what 
the staff considers to be an acceptable method of meeting the NRC 
regulations. Previous revisions should not be used by applicants for 
new licensing actions. NRC staff believes that continued use of 
previous revisions of the Regulatory Guide by existing nuclear power 
plant licensees is acceptable (i.e., meets all NRC requirements, and 
provides reasonable assurance of adequate protection to public health 
and safety, and common defense and security). Revision of this 
Regulatory Guide does not modify any prior commitments made by 
licensees to the NRC or Agreement States. Therefore, a licensee that 
has made a commitment must continue to meet that prior commitment, or 
the commitment should be modified in accordance with the licensee's 
commitment management process. The previous revision of this Regulatory 
Guide will continue to be publically available on the NRC public Web 
site.
