United States Code II. Purpose and Legal Basis The purpose of this rule is to update the Coast Guard's chapters in the Code of Federal Regulations

(CFR)to reflect the renaming of our districts. This is a conforming amendment regarding the Coast Guard's organization. This final rule is issued under the authority of 5 United States Code (U.S.C.) 552(a) and 553; 14 U.S.C. 102, 503, and 504; and Department of Homeland Security

(DHS)Delegation No. 00170.1(II)(23) Revision No. 01.4. As explained in 33 CFR 1.05-1(h), the Chief of the Coast Guard's Office of Regulations and Administrative Law has been delegated authority to issue regulations necessary to implement technical, organizational, and conforming amendments and corrections to regulations. We did not publish a notice of proposed rulemaking before this final rule. The Coast Guard finds that this rule is exempt from notice and comment rulemaking requirements under 5 U.S.C. 553(b)(A) because the district renaming is a conforming amendment involving agency organization. Updating the district names in the CFR imposes no substantive changes on the public's rights or obligations and will be inconsequential in impact. The Coast Guard finds good cause exists under 5 U.S.C. 553(d)(3) to make the rule effective fewer than 30 days after publication in the **Federal Register** . Delaying the effective date of the rule is unnecessary because updating the district name we use in our regulations is inconsequential to the public and the name has already been adopted by the Coast Guard in agency practice. III. Background The Coast Guard announced the renaming of the districts in a message, ALCOAST 305/25, “Force Design 2028—Renaming Coast Guard Districts” on July 3, 2025. A copy of the ALCOAST is available in the docket under the ADDRESSES section of this preamble. As explained in the ALCOAST, when the Coast Guard operated as part of the Navy during World War II it adopted the Navy's numbered district system to ensure alignment between the services. In the 80 years since the end of World War II, the Coast Guard has maintained its numbered districts. However, the Navy stopped using numbered districts over 25 years ago. Renaming Coast Guard districts to reflect their geographical location will help the public and maritime stakeholders easily find and understand which Coast Guard district they live, boat, and operate in. In the ALCOAST we explained the name change will not impact operations or change existing geographical district boundaries. The ALCOAST also stated we would change district names in the CFR in coming months. IV. Discussion of Final Rule This final rule updates the CFR to reflect the renaming of Coast Guard operational districts from numerical to geographic names. The geographic names more clearly align districts with their areas of responsibility, improve collaboration with interagency partners, and ensure the public and maritime stakeholders can easily find and understand the districts in which they live, recreate, and operate. The new geographic names are as follows: Previous numerical district name New geographical district name District 1 USCG Northeast District. District 5 USCG East District. District 7 USCG Southeast District. District 8 USCG Heartland District. District 9 USCG Great Lakes District. District 11 USCG Southwest District. District 13 USCG Northwest District. District 14 USCG Oceania District. District 17 USCG Arctic District. The Coast Guard periodically issues technical, organizational, and conforming amendments to existing regulations. These conforming amendments provide the public with accurate and current regulatory information but do not change the effect of any Coast Guard regulations on the public. This rule also revises the authority citations in several parts of the CFR solely to update the DHS Delegation No. 00170.1 to the most current revision number 01.4. V. Regulatory Analyses We developed this rule after considering numerous statutes and Executive orders related to rulemaking. A summary of our analyses based on these statutes or Executive orders follows. A. Regulatory Planning and Review Executive Order 14192 (Unleashing Prosperity Through Deregulation) directs agencies to significantly reduce the private expenditures required to comply with Federal regulations and provides that “any new incremental costs associated with new regulations shall, to the extent permitted by law, be offset by the elimination of existing costs associated with at least 10 prior regulations.” This rule is not an Executive Order 14192 regulatory action because this rule is not significant under Executive Order 12866. See OMB Memorandum M-25-20, “Guidance Implementing Section 3 of Executive Order 14192, titled `Unleashing Prosperity Through Deregulation' ” (March 26, 2025). The name change will have no substantive effect on the public. A regulatory analysis

(RA)follows. This rule involves non-substantive technical amendments and updates to internal agency practices and procedures and will not impose any additional costs. The technical amendments in this rule modify existing language in the CFR. The Coast Guard does not expect any additional costs for the public or the Federal Government because none of the technical and editorial changes included in this rule will change existing regulatory requirements. Specifically, renaming the districts to reflect their geographical location will help the public and maritime stakeholders easily find and understand which Coast Guard district they live, boat, and operate in, leading to less confusion. A summary of these amendments by numerical district name and geographical district name are presented in table 1. Table 1—Summary of Regulatory Changes by District Number and Name Previous numerical district name New geographical district name Description of changes Economic impact District 1 USCG Northeast District Editorial No impact; editorial changes. District 5 USCG East District Editorial No impact; editorial changes. District 7 USCG Southeast District Editorial No impact; editorial changes. District 8 USCG Heartland District Editorial No impact; editorial changes. District 9 USCG Great Lakes District Editorial No impact; editorial changes. District 11 USCG Southwest District Editorial No impact; editorial changes. District 13 USCG Northwest District Editorial No impact; editorial changes. District 14 USCG Oceania District Editorial No impact; editorial changes. District 17 USCG Arctic District Editorial No impact; editorial changes. The unquantified benefits of these non-substantive technical amendments are increased accuracy of regulatory information by removing expired or cancelled provisions that are no longer relevant. Further, these changes will improve public understanding and accessibility of Coast Guard regulations, ensuring that the public benefits from accurate regulatory text and reduced confusion. B. Small Entities Under the Regulatory Flexibility Act, 5 U.S.C. 601-612, we have considered whether this rule would have a significant economic impact on a substantial number of small entities. The term “small entities” comprises small businesses, not-for-profit organizations that are independently owned and operated and are not dominant in their fields, and governmental jurisdictions with populations of less than 50,000 people. Under 5 U.S.C 604(a), a regulatory flexibility analysis is not required for this final rule because under the provision in section 553(b)(A) we were not required to publish a general notice of a proposed rulemaking. Therefore, we did not conduct a regulatory flexibility analysis for this rule. C. Assistance for Small Entities Under section 213(a) of the Small Business Regulatory Enforcement Fairness Act of 1996, Public Law 104-121, we want to assist small entities in understanding this final rule so that they can better evaluate its effects on them and participate in the rulemaking. The Coast Guard will not retaliate against small entities that question or complain about this rule or any policy or action of the Coast Guard. D. Collection of Information This rule calls for no new collection of information under the Paperwork Reduction Act of 1995, 44 U.S.C. 3501, 3520. E. Federalism A rule has implications for federalism under Executive Order 13132 (Federalism) if it has a substantial direct effect on States, on the relationship between the National Government and the States, or on the distribution of power and responsibilities among the various levels of government. We have analyzed this rule under Executive Order 13132 and have determined that it is consistent with the fundamental federalism principles and preemption requirements described in Executive Order 13132. F. Unfunded Mandates The Unfunded Mandates Reform Act of 1995, 2 U.S.C. 1531, 1538, requires Federal agencies to assess the effects of their discretionary regulatory actions. In particular, the Act addresses actions that may result in the expenditure by a State, Local, or Tribal government, in the aggregate, or by the private sector of $100 million (adjusted for inflation) or more in any one year. Although this rule will not result in such an expenditure, we do discuss the potential effects of this rule in this preamble. G. Taking of Private Property This rule will not cause a taking of private property or otherwise have taking implications under Executive Order 12630 (Governmental Actions and Interference with Constitutionally Protected Property Rights). H. Civil Justice Reform This rule meets applicable standards in sections 3(a) and 3(b)(2) of Executive Order 12988, (Civil Justice Reform), to minimize litigation, eliminate ambiguity, and reduce burden. I. Protection of Children We have analyzed this rule under Executive Order 13045 (Protection of Children from Environmental Health Risks and Safety Risks). This rule is not an economically significant rule and will not create an environmental risk to health or risk to safety that might disproportionately affect children. J. Indian Tribal Governments This rule does not have Tribal implications under Executive Order 13175 (Consultation and Coordination with Indian Tribal Governments) because it will not have a substantial direct effect on one or more Indian Tribes, on the relationship between the Federal Government and Indian Tribes, or on the distribution of power and responsibilities between the Federal Government and Indian Tribes. K. Energy Effects We have analyzed this rule under Executive Order 13211 (Actions Concerning Regulations That Significantly Affect Energy Supply, Distribution, or Use). We have determined that it is not a “significant energy action” under that order because it is not a “significant regulatory action” under Executive Order 12866 and is not likely to have a significant adverse effect on the supply, distribution, or use of energy. L. Environment We have analyzed this rule under DHS Management Directive 023-01, Rev. 1, associated implementing instructions, and Environmental Planning COMDTINST 5090.1 (series), which guide the Coast Guard in complying with the National Environmental Policy Act of 1969 (42 U.S.C. 4321-4370f), and have made a determination that this action is one of a category of actions that do not individually or cumulatively have a significant effect on the human environment. A Record of Environmental Consideration supporting this determination is available in the docket. For instructions on locating the docket, see the ADDRESSES section of this preamble. This final rule is categorically excluded under paragraph A3, and L54 of Appendix A, Table 1 of DHS Instruction Manual 023-01-001-01, Rev. 1. The categorical exclusion (CATEX) A3 pertains to the promulgation of rules, issuance of rulings or interpretations, and the development and publication of policies, orders, directives, notices, procedures, manuals, advisory circulars, and other guidance documents of the following nature:

(a)those of a strictly administrative or procedural nature,

(b)those that implement, without substantive change, statutory or regulatory requirements,

(c)those that implement, without substantive change, procedures, manuals, and other guidance documents, and

(d)those that interpret or amend an existing regulation without changing its environmental effect,

(e)technical guidance on safety and security matters, or

(f)guidance for the preparation of security plans. CATEX L54 pertains to regulations which are editorial or procedural. This final rule involves non-substantive technical, organizational, and conforming amendments to existing Coast Guard regulations for district name changes.
