# SUPPLEMENTARY INFORMATION:

## I. Introduction

The U.S. Nuclear Regulatory Commission (NRC) is issuing for public comment a draft regulatory 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), titled, “Guidance on Making Changes to Emergency Response Plans for Nuclear Power Reactors,” is temporarily identified by its task number, DG-1237, which should be mentioned in all related correspondence. This is a new guide.

                    The NRC staff's objectives for Title 10, section 50.54(q), of the Code of Federal Regulations (10 CFR 50.54(q)) are to ensure that licensees (1) Follow and maintain the effectiveness of their approved emergency plans, (2) evaluate proposed changes to these plans for their impact on the effectiveness of the plans, and (3) obtain prior NRC approval for changes that would reduce the effectiveness of the plans. These actions are essential if these plans are to continue to provide reasonable assurance that adequate protective measures can and will be taken in the event of a radiological emergency. The NRC is proposing changes to 10 CFR 50.54(q) based on lessons learned from operating experience and at the direction of the Commission. The purpose of this draft guide is to provide guidance on the implementation of proposed revision of 10 CFR 50.54(q) with respect to making changes to emergency response plans. The                           ( print page 23221)                        proposed changes to 10 CFR 50.54(q) can be found at the Federal e-Rulemaking Portal (                    *http://www.regulations.gov*) by searching on Docket ID: NRC-2008-0122.                

## II. Further Information

The NRC staff is soliciting comments on DG-1237. Comments may be accompanied by relevant information or supporting data, and should mention DG-1237 in the subject line.

Personal information will not be removed from the comments. Comments may be submitted by any of the following methods:
