environmental qualification (EQ) of certain electric equipment
important to safety.
DATES: Revision 2 to RG 1.89 is available on May 3, 2023.

SUPPLEMENTARY INFORMATION:
I. Discussion
The NRC is issuing a revision in the NRC's ``Regulatory Guide''
series. This series was developed to describe methods that are
acceptable to the NRC staff for implementing specific parts of the
agency's regulations, to explain techniques that the staff uses in
evaluating specific issues or postulated events, and to describe
information that the staff needs in its review of applications for
permits and licenses.
Revision 2 to RG 1.89 was issued with a temporary identification of
Draft Regulatory Guide, DG-1361 (ADAMS Accession No. ML20183A423).
The staff revised RG 1.89 to endorse, with clarifications,
exceptions, and supplements, International Electrotechnical Commission/
Institute of Electrical and Electronic Engineers Standard 60780-323,
``Nuclear Facilities--Electrical Equipment Important to Safety--
Qualification,'' Edition 1, 2016-02, as this standard reflects almost
40 years of experience gained in implementing regulatory requirements
and industry research and testing related to environmental
qualification (EQ). Nuclear plant license renewal provides additional
motivation for continuing attention to equipment qualification. This
revised guide contains information specific for EQ for both older
plants and newer reactors licensed under parts 50 and 52 of title 10 of
the Code of Federal Regulations (10 CFR).
II. Additional Information
The NRC published notices of the availability of DG-1361 in the
Federal Register on December 17, 2020 (85 FR 81958) and February 18,
2021 (86 FR 10133) for 60-day public comment periods. The public
comment periods closed on February 16, 2021, and April 19, 2021,
respectively. Public comments on DG-1361 and the staff responses to the
public comments are available under ADAMS under Accession No.
ML22272A601.
As noted in the Federal Register on December 9, 2022 (87 FR 75671),
this document is being published in the ``Rules'' section of the
Federal Register to comply with publication requirements under 1 CFR
chapter I.
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. Backfitting, Forward Fitting, and Issue Finality
Issuance of RG 1.89, Revision 2, does not constitute backfitting as
defined in 10 CFR 50.109, ``Backfitting,'' and as described in NRC
Management Directive (MD) 8.4, ``Management of Backfitting, Forward
Fitting, Issue Finality, and Information Requests''; affect the issue
finality of an approval issued under 10 CFR part 52; or constitute
forward fitting as defined in MD 8.4 because, as explained in this RG,
licensees are not required to comply with the positions set forth in
this RG.
V. Submitting Suggestions for Improvement of Regulatory Guides
A member of the public may, at any time, submit suggestions to the
NRC for improvement of existing RGs or for the development of new RGs.
Suggestions can be submitted on the NRC's public website at https://www.nrc.gov/reading-rm/doc-collections/reg-guides/contactus.html.
Suggestions will be considered in future updates and enhancements to
the ``Regulatory Guide'' series.
