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. 

The proposed Revision 4 to RG 4.7 

was issued with a temporary 

identification of Draft Regulatory Guide 

(DG)–4034. The NRC staff revised RG 

4.7 to include alternative approaches to 

the population-density criterion and to 

expand the regulatory guidance 

developed for large light-water reactor 

(LWR) technology with appropriate 

modifications for advanced reactor 

designs (e.g., non-LWR technologies and 

light-water small modular reactors). 

Specifically, this revision includes a 

new appendix A, which implements the 

Commission approved alternative 

population-related criteria in SRM– 

SECY–20–0045 ‘‘Population-Related 

Siting Considerations for Advanced 

Reactors,’’ (ADAMS Accession No. 

ML22194A885). Appendix A provides 

guidance on alternatives to the existing 

guidance in section C.1.4 of this RG that 

establishes a fixed distance of 20 miles 

out to which population density is 

assessed for any new application. 

Readers should understand that the 

body of this RG was developed for large 

LWRs, while appendix A is intended for 

advanced reactor designs. This revision 

also removes repetition and improves 

clarity. Text from the discussion section 

and the two tables in Revision 3 to the 

RG were brought together in Section C, 

‘‘Staff Regulatory Guidance.’’ To present 

each topic in Section C cohesively, the 

document was structured to list (1) 

relevant statutes and regulations, (2) 

related guidance, and (3) considerations, 

regulatory experience, and staff 

positions. 

II. Additional Information

The NRC published a notice of the

availability of DG–4034 in the Federal 

Register on October 18, 2023 (88 FR 

71777) for a 30-day public comment 

period. The public comment period 

closed on November 17, 2023. Public 

comments on DG–4034 and the staff 

responses to the public comments are 

available in ADAMS under Accession 

No. ML23324A007. 

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 chapter I of title 1 

of the Code of Federal Regulations 

(CFR). 

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 this RG does not 

constitute backfitting as defined in 10 

CFR 50.109, ‘‘Backfitting,’’ and as 

described in NRC Management Directive 


khammond on DSKJM1Z7X2PROD with RULES
14744 Federal Register / Vol. 89, No. 41 / Thursday, February 29, 2024 / Rules and Regulations 

(MD) 8.4, ‘‘Management of Backfitting, 

Forward Fitting, Issue Finality, and 

Information Requests,’’ would not affect 

the issue finality of any approval issued 

under 10 CFR part 52; and would not 

constitute forward fitting as that term is 

defined and described in MD 8.4. This 

RG will not apply to any construction 

permits, operating licenses, early site 

permits, limited work authorizations 

issued under 10 CFR 50.10, or combined 

licenses, for which the NRC issued a 

final environmental impact statement 

(EIS) preceded by a draft EIS under 10 

CFR 51.76 or 51.75, any of which were 

issued by the NRC prior to issuance of 

this final RG. The NRC has already 

completed its siting determination for 

those construction permits, operating 

licenses, early site permits, limited work 

authorizations, and combined licenses. 

Therefore, no further NRC regulatory 

action on siting will occur for those 

licenses, permits, and authorizations, 

for which the guidance in the RG would 

be relevant. The methods described in 

this RG will be used in evaluating 

applications for construction permits, 

early site permits, combined operating 

licenses and limited work 

authorizations, which includes 

information under 10 CFR 51.49(b) or 

(f), with respect to compliance with 

applicable regulations governing the 

siting of new nuclear power plants and 

testing facilities, unless the applicant 

proposes an acceptable alternative 

method for complying with those 

regulations. Methods that differ from 

those described in this RG may be 

deemed acceptable if the applicant 

provides sufficient basis and 

information for the NRC staff to verify 

that the proposed alternative complies 

with the applicable NRC regulations. 

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/readingrm/doc-collections/reg-guides/ 

contactus.html. Suggestions will be 

considered in future updates and 

enhancements to the ‘‘Regulatory 

Guide’’ series.

Coast Guard 

33 CFR Part 117 

[Docket No. USCG–2023–0183] 

RIN 1625–AA09 

Drawbridge Operation Regulation; 

River Rouge, Detroit, MI; Correction 

AGENCY: Coast Guard, Department of 

Homeland Security (DHS). 

ACTION: Correcting amendment. 

SUMMARY: The Coast Guard is correcting 

regulations that published in the 

Federal Register on December 28, 2023. 

The final rule announced changes to the 

operations of all movable bridges over 

the River Rouge, Detroit, MI, to improve 

communications and establish winter 

hours. This correction fixes incorrect 

language in the regulations. The 

language in the final rule inadvertently 

stated the draw of the Dix Avenue 

Bridge, mile 2.73, is remotely operated, 

when it is not equipped or authorized 

to operate remotely. 

DATES: This correcting amendment is 

effective February 29, 2024. 

FOR FURTHER INFORMATION CONTACT: If 

you have questions on this correcting 

amendment, call or email Mr. Lee D. 

Soule, Bridge Management Specialist, 

Ninth Coast Guard District; telephone 

216–902–6085, email Lee.D.Soule@

uscg.mil. 

SUPPLEMENTARY INFORMATION: In FR Doc. 

2023–28645, appearing on page 89574 

in the Federal Register of December 28, 

2023, the final rule inadvertently 

identified in paragraph (h) that the 

bridge is remotely operated. The Coast 

Guard did not intend to include this text 

in § 117.645(h). Therefore, we are 

correcting paragraph (h) by removing 

the words ‘‘is remotely operated’’. 

List of Subjects in 33 CFR Part 117 

Bridges. 

For the reasons discussed in the 

preamble, the Coast Guard corrects 33 

CFR part 117 by making the following 

correcting amendment: 

PART 117—DRAWBRIDGE 

OPERATION REGULATIONS 

■ 1. The authority citation for part 117 

continues to read as follows: 

Authority: 33 U.S.C. 499; 33 CFR 1.05–1; 

and DHS Delegation No. 00170.1, Revision 

No. 01.3. 

■ 2. Amend § 117.645 by revising 

paragraph (h) to read as follows: 

§ 117.645 River Rouge. 

* * * * * 

(h) The draw of the Dix Avenue 

Bridge, mile 2.73, is required to operate 

a radiotelephone, and shall open on 

signal except from January 1 through 

March 31 when the bridge shall open on 

signal if provided a 12-hour advance 

notice.

Drawbridge Operation Regulation; 

Ashtabula River, Ashtabula, OH 

AGENCY: Coast Guard, Department of 

Homeland Security (DHS). 

ACTION: Final rule. 

SUMMARY: The Coast Guard is modifying 

the operating schedule that governs the 

Fifth Street Bridge, mile 0.15, and the 

Norfolk Southern Railroad Bridge, mile 

1.5, both over the Ashtabula River. The 

Coast Guard is also changing signaling 

and signage requirements for the 

Norfolk Southern Railroad Bridge, mile 

1.5. The Coast Guard is modifying these 

rules in response to complaints received 

concerning the operations of one or 

more bridges over the waterway and a 

desire to improve safety, remove 

barriers to interstate commerce, improve 

communications, and standardize 

winter operations associated with these 

bridges. 

DATES: This rule is effective April 1, 

2024.
