# SUPPLEMENTARY INFORMATION:

## I. Introduction

                    The NRC is issuing a revision to an existing guide in the NRC's “Regulatory Guide” series. Regulatory guides were developed to describe and make available to the public information and methods that are acceptable to the NRC staff for implementing specific parts of the agency'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 NRC typically seeks public comment on a draft version of a RG by announcing its availability for comment in the                     **Federal Register**                    .  However, as explained on page 7 of NRC's Management Directive 6.6 “Regulatory Guides,” (ADAMS Accession No. ML110330475) the NRC may directly issue a final RG without a draft version or public comment-period if the changes to the RG are non-substantive.                

The NRC is issuing Revision 1 of RG 5.74 directly as a final RG because the changes between Revision 0 and Revision 1 are non-substantive. Revision 1 of RG 5.74 incorporated editorial changes and updated the guide to the current format for RGs and is administrative in nature. These changes were intended to improve clarity and did not substantially alter the staff's regulatory guidance. These changes included additional questions to assist the user in the screening of planned and emergent activities or changes, and clarification to the requirement that the safety-security interface must be maintained at all times.

## II. Backfitting and Issue Finality

                    Issuance of this final RG does not constitute backfitting as defined in section 50.109 of title 10 of the                     *Code of Federal Regulations*                     (10 CFR), (the Backfit Rule), and is not otherwise inconsistent with the issue finality provisions in 10 CFR part 52. The changes in Revision 1 of RG 5.74 are limited to editorial changes to improve clarity and the correction of a title. These changes do not fall within the kinds of agency actions that constitute backfitting or are subject to limitations in the issue finality provisions of part 52. Accordingly, the NRC did not address the Backfit Rule or issue finality provisions of part 52.                

## III. Congressional Review Act

This RG is a rule as defined in the Congressional Review Act (5 U.S.C. 801-808). However, the Office of Management and Budget has not found it to be a major rule as defined in the Congressional Review Act.

## IV. Submitting Suggestions for Improvement of Regulatory Guides

                    Revision 1 of RG 5.74 is being issued without public comment. However, you may at any time submit suggestions to the NRC for improvement of existing RGs or for the development of new RGs to address new issues. Suggestions can be submitted by the form available online at                     *http://www.nrc.gov/​reading-rm/​doc-collections/​reg-guides/​contactus.html.*                     Suggestions will be considered in future updates and enhancements of the RG.                

Dated at Rockville, Maryland, this 14th day of April, 2015.

For the Nuclear Regulatory Commission.

Acting Chief, Regulatory Guidance and Generic Issues Branch, Division of Engineering, Office of Nuclear Regulatory Research.
