B. Submitting Comments

    The NRC encourages electronic comment submission through the 
Federal rulemaking website (https://www.regulations.gov). Please 
include Docket ID NRC-2023-0068 in your comment submission.
    The NRC cautions you not to include identifying or contact 
information that you do not want to be publicly disclosed in your 
comment submission. The NRC will post all comment submissions at 
https://www.regulations.gov as well as enter the comment submissions 
into ADAMS. The NRC does not routinely edit comment submissions to 
remove identifying or contact information.
    If you are requesting or aggregating comments from other persons 
for submission to the NRC, then you should inform those persons not to 
include identifying or contact information that they do not want to be 
publicly disclosed in their comment submission. Your request should 
state that the NRC does not routinely edit comment submissions to 
remove such information before making the comment submissions available 
to the public or entering the comment into ADAMS.

II. Additional Information

    The NRC is issuing for public comment a DG 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.
    The DG, entitled ``Cybersecurity Event Notifications,'' (ADAMS 
Accession No. ML22250A443) is temporarily identified by its task 
number, DG-5079, which is proposed Revision 1 of RG 5.83 of the same 
name.
    The DG describes methods that the staff of the NRC considers 
acceptable for licensees to report and record cybersecurity events as 
required under section 73.77 of title 10 of the Code of Federal 
Regulations (10 CFR), ``Cyber security event notifications.'' This 
guide applies to nuclear power reactor licensees that are licensed to 
operate under 10 CFR part 50, ``Domestic Licensing of Production and 
Utilizations

[[Page 24716]]

Facilities,'' or 10 CFR part 52, ``Licenses, Certifications, and 
Approvals for Nuclear Power Plants.''
    The staff is also issuing for public comment a regulatory analysis 
(ADAMS Accession No. ML22250A472). The staff developed a regulatory 
analysis to assess the value of issuing or revising a regulatory guide 
as well as alternative courses of action.
    As noted in the Federal Register on December 9, 2022 (87 FR 75671), 
this document is being published in the ``Proposed Rules'' section of 
the Federal Register to comply with publication requirements under 1 
CFR chapter I.

III. Backfitting, Forward Fitting, and Issue Finality

    Issuance of DG-5079, if finalized, would 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'' (ADAMS Accession 
No. ML18093B087); constitute forward fitting as that term is defined 
and described in MD 8.4; or affect issue finality of any approval 
issued under 10 CFR part 52, ``Licenses, Certifications, and Approvals 
for Nuclear Power Plants.'' As explained in DG-5079, applicants and 
licensees would not be required to comply with the positions set forth 
in this guide.

IV. 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.
