Regulatory guide; issuance.
The U.S. Nuclear Regulatory Commission (NRC) is issuing revision 2 of Regulatory Guide (RG) 1.137, “Fuel Oil Systems for Emergency Power Supplies.” Revision 2 of RG 1.137 endorses ANSI/ANS-59.51-1997, “Fuel Oil Systems for Safety-Related Emergency Diesel Generators,” (reaffirmed in October 2007) with the exceptions and clarification stated in the RG. ANSI/ANS-59.51-1997 describes methods that the NRC considers acceptable for use in complying with NRC regulations for assuring the quality of fuel oil for emergency diesel generators used in nuclear power plants.

Start Supplemental Information
The NRC is issuing a revision to an existing guide in the NRC's “Regulatory Guide” series. This series was developed to describe and make available to the public information such 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.
II. Further Information
Revision 2 of RG 1.137 endorses American National Standards Institute (ANSI), American Nuclear Society (ANS) (ANSI/ANS) Standard 59.51-1997, “Fuel Oil Systems for Safety-Related Emergency Diesel Generators,” (reaffirmed in October 2007), and American Society for Testing and Materials (ASTM) standard D975-13, “Standard Specification for Diesel Fuel Oils,” with the exceptions stated in the regulatory positions. Both ANSI/ANS-59.51-1997 and ASTM D975-13 describe methods the NRC considers acceptable for use in complying with NRC requirements for assuring the quality of fuel oil and fuel oil systems for emergency diesel generators used in nuclear power plants. The methods described in ANSI/ANS 59.51-1997 and ASTM D975-13 are consistent with NRC requirements derived from “General Design Criteria (GDC) 17, Electric Power Systems” in Appendix A to Part 50 of Title 10, of the Code of Federal Regulations (10 CFR), Start Printed Page 36279“Domestic Licensing of Production and Utilization Facilities,” and 10 CFR 50.55a.
The 1979 revision to RG 1.137 endorsed the guidance in ANSI Standard N195-1976, “Fuel Oil Systems for Standby Diesel-Generators.” The ANSI standard was revised in 1989 and reformatted and revised in 1997 as ANSI/ANS-59.51-1997 with no change to RG 1.137. Revision 2 of RG 1.137 endorses the most current version of the ANSI/ANS standard.
Revision 2 of RG 1.137 was issued with a temporary identification as Draft Regulatory Guide, DG-1282 on July 5, 2012 (77 FR 39745) for a 60-day public comment period. The public comment period was extended until September 28, 2012 (77 FR 48177). Public comments were received and addressed by the NRC staff. These comments and the NRC staff responses are available in ADAMS under Accession No. ML12300A121.
The NRC prepared a regulatory analysis for the development of DG-1285 and it is available in ADAMS under Accession No. ML121090459.
Revision 2 of RG 1.137 supersedes Revision 1 of RG 1.137, and represents the NRC staff's guidance for future users and applications. Earlier versions of this regulatory guide, however, continue to be acceptable for those licensees whose licensing basis includes earlier versions of this regulatory guide, absent a licensee-initiated change to its licensing basis. Additional information on the staff's use of this revised regulatory guide with respect to both current and future users and applications is set forth in the “Implementation” section of the revised regulatory guide.
III. Backfitting and Issue Finality
Issuance of this final regulatory guide does not constitute backfitting as defined in 10 CFR 50.109 (the Backfit Rule) and is not otherwise inconsistent with the issue finality provisions in 10 CFR Part 52. As discussed in the “Implementation” section of this regulatory guide, the NRC has no current intention to impose this regulatory guide on holders of current operating licenses or combined licenses.
This regulatory guide may be applied to applications for operating licenses and combined licenses docketed by the NRC as of the date of issuance of the final regulatory guide, as well as future applications for operating licenses and combined licenses submitted after the issuance of the regulatory guide. Such action does not constitute backfitting as defined in 10 CFR 50.109(a)(1) or is otherwise inconsistent with the applicable issue finality provision in 10 CFR Part 52, inasmuch as such applicants or potential applicants are not within the scope of entities protected by the Backfit Rule or the relevant issue finality provisions in Part 52.
Congressional Review Act
This regulatory guide is a rule as designated in the Congressional Review Act (5 U.S.C. 801-808). However, the Office of Management and Budget (OMB) has not found it to be a major rule as designated in the Congressional Review Act.
