SUPPLEMENTARY INFORMATION: 

I. Introduction

    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 
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.
    Revision 2 of RG 1.106 was issued with a temporary identification 
as Draft Regulatory Guide, DG-1264. This regulatory guide describes a 
method acceptable to the NRC staff regarding the application of thermal 
overload protection devices. This method would ensure that the thermal 
overload protection devices will not needlessly prevent the motor from 
performing its safety-related function.

II. Further Information

    DG-1264, was published in the Federal Register on May 02, 2011 (76 
FR 24538) for a 60-day public comment period. The public comment period 
closed on June 28, 2011. The NRC staff's responses to the public 
comments on DG-1264 are available under ADAMS Accession Number 
ML112580363.

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'' discussion of this 
regulatory guide, the NRC has no current intention to impose this 
regulatory guide on holders of current operating licenses or combined 
licenses. Accordingly, the issuance of this regulatory guide does not 
constitute ``backfitting''' as defined in 10 CFR 50.109(a)(1) or is 
otherwise inconsistent with the applicable issue finality provisions in 
10 CFR Part 52.
    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 CRF 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 10 CFR Part 52.

    Dated at Rockville, Maryland, this 17th day of February 2012.

    For the Nuclear Regulatory Commission.
Mark P. Orr,
Acting Chief, Regulatory Guide Development Branch, Division of 
Engineering, Office of Nuclear Regulatory Research.
