Temporary interim rule and request for comments.
**SUMMARY:**
The Coast Guard is extending the effective period of the current temporary safety zone to December 31, 2025.

King Airport in St. Thomas, USVI. Entry of vessels or persons into this zone is prohibited unless specifically authorized by the Captain of the Port Sector San Juan.
**DATES:**
*Effective date:* This rule is effective without actual notice from November 21, 2025 through December 31, 2025. For the purposes of enforcement, actual notice will be used from October 1, 2025, through November 21, 2025.
*Comments due date:* Comments and related material must be received by the Coast Guard on or before December 22, 2025.

**II. Background Information and Regulatory History**
On August 25, 2025, the Coast Guard established a temporary final rule establishing a safety zone for the runway of Cyril E. King Airport in St. Thomas, USVI. [^1] The Coast Guard originally published the temporary final rule to be effective through September 30, 2025. We are now extending it to December 31, 2025, to provide an opportunity for comment before we establish a permanent safety zone.
[^1] 90 FR 41301.
The Coast Guard is issuing this temporary interim rule under the authority in 5 U.S.C. 553(b)(B). This statutory provision authorizes an agency to issue a rule without prior notice and opportunity to comment when the agency for good cause finds that those procedures are “impracticable, unnecessary, or contrary to the public interest.” The Coast Guard finds that good cause exists for not publishing a notice of proposed rulemaking (NPRM) with respect to this temporary interim rule because there is an immediate need to mitigate the risk of vessels transiting between private port authority managed yellow buoys & the end of the St. Thomas Cyril E. King runway because of their proximity to the low flying aircrafts. Prompt action is needed to respond to the potential safety hazards associated with vessels transiting in the proximity of the runway of Cyril E. King Airport in St. Thomas, USVI. It is impracticable to publish an NPRM because we must establish this safety zone by October 1, 2025.
Also, under 5 U.S.C. 553(d)(3), the Coast Guard finds that good cause exists for making this temporary interim rule effective less than 30 days after publication in the *Federal Register* . The current temporary final rule around the St. Thomas Cyril E. King runway ends on September 30, 2025; however, the need for the safety zone continues. Delaying the effective date of this temporary interim rule would be impracticable because prompt action is needed starting on October 1, 2025, to respond to the potential safety hazards associated with vessels transiting between private port authority managed yellow buoys & the end of the St. Thomas Cyril E. King runway and their proximity to the low flying aircrafts.
We are soliciting comments on the extension of the enforcement period of this safety zone. Persons wishing to comment may do so by submitting written comments to the office listed under *ADDRESSES* in this preamble. Commenters should include their names and addresses, identify the docket number for the regulation, and give reasons for their comments.
**III. Legal Authority and Need for Rule**
The Coast Guard is issuing this temporary interim rule under authority in 46 U.S.C. 70034. The Captain of the Port Sector San Juan (COTP) has determined potential hazards associated with vessels transiting between private port authority managed yellow buoys & the end of the St. Thomas Cyril E. King runway and their proximity to the low flying aircrafts. There is a safety concern for any vessel transiting within approximately 400 yards from shore directly west of the airport's runway. This temporary interim rule is needed to protect personnel, vessels, and the marine environment in the navigable waters within the safety zone.
**IV. Discussion of the Rule**
On August 25, 2025, the Coast Guard established a temporary safety zone for navigable waters west of the Cyril E. King Airport in St. Thomas, U.S. Virgin Islands. This temporary interim rule extends the effective period through December 31, 2025, to give an opportunity for comment before the Coast Guard establishes a permanent safety zone. The temporary safety zone covers all navigable waters within 400 yards from shore directly west of the airport's runway within the two private port authority managed yellow buoys located at 18°20.288′ N−64°59.343′ W and 18°20.116′ N−64°59.343′ W. No vessel or person will be permitted to enter the safety zone without obtaining permission from the COTP or a designated representative.
**V. Regulatory Analyses**
We developed this rule after considering numerous statutes and Executive orders related to rulemaking. Below we summarize our analyses based on a number of these statutes and Executive orders.
**A. Impact on Small Entities**
The regulatory flexibility analysis provisions of the Regulatory Flexibility Act of 1980, 5 U.S.C. 601-612, do not apply to rules that are not subject to notice and comment. Because the Coast Guard has, for good cause, waived the notice and comment requirement that would otherwise apply to this rulemaking, the Regulatory Flexibility Act's flexibility analysis provisions do not apply here.
Under section 213(a) of the Small Business Regulatory Enforcement Fairness Act of 1996 (Pub. L. 104-121), if this rule will affect your small business, organization, or governmental jurisdiction and you have questions, contact the person listed in the *FOR FURTHER INFORMATION CONTACT* section.
Small businesses may send comments to the Small Business and Agriculture Regulatory Enforcement Ombudsman and the Regional Small Business Regulatory Fairness Boards by calling 1-888-REG-FAIR (1-888-734-3247). 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.
**B. Collection of Information**
This rule will not call for a new collection of information under the Paperwork Reduction Act of 1995 (44 U.S.C. 3501-3520).
**C. Federalism and Indian Tribal Governments**
A rule has implications for federalism under Executive Order 13132, Federalism, if it has a substantial direct effect on the 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 that Order and have determined that it is consistent with the fundamental federalism principles and preemption requirements described in Executive Order 13132.
Also, this rule does not have tribal implications under Executive Order 13175, Consultation and Coordination with Indian Tribal Governments, because it does 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.
**D. Unfunded Mandates Reform Act**
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 $100,000,000 (adjusted for inflation) or more in any one year. Though this rule will not result in such an expenditure, we do discuss the effects of this rule elsewhere in this preamble.
**E. Environment**
We have analyzed this rule under Department of Homeland Security 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 determined that this action is one of a category of actions that do not individually or cumulatively have a significant effect on the human environment. This rule involves safety zone that will prohibit entry within 400 yards from shore directly west of the airport's runway within the two private port authority managed yellow buoys. It is categorically excluded from further review under paragraph L60(a) of Appendix A, Table 1 of DHS Instruction Manual 023-01-001-01, Rev. 1. 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.
