AGENCY:
Coast Guard, Department of Homeland Security.

Temporary final rule.
SUMMARY:
The Coast Guard is establishing a temporary safety zone for navigable waters within 200 yards radius around the Barge DEFIANT grounded north of El Morro, east of the green buoy three, near the entrance of the San Juan Harbor. The safety zone is needed to protect personnel, vessels, and the marine environment from potential hazards created by the Barge DEFIANT grounding. Entry of vessels or persons into this zone is prohibited unless specifically authorized by the Captain of the Port, Sector San Juan.
DATES:
This rule is effective without actual notice from February 18, 2026 through February 23, 2026. For the purposes of enforcement, actual notice will be used from February 9, 2026, until February 18, 2026.

NPRM Notice of proposed rulemaking
§ Section
U.S.C. United States Code
II. Background and Authority
The Coast Guard received notification that the Barge DEFIANT grounded north of El Morro, east of the green buoy three, near the entrance of the San Juan Harbor. The Captain of the Port (COTP) San Juan has determined that potential hazards associated with the vessel grounding are a safety concern for anyone within 200 yards radius around the grounded Barge DEFIANT barge. Therefore, the COTP is issuing this rule under the authority in 46 U.S.C. 70034, which is needed to protect personnel, vessels, and the marine environment in the navigable waters within the safety zone.
For the same reasons, the Coast Guard finds that under 5 U.S.C. 553(d)(3), good cause exists for making this rule effective less than 30 days after publication in the Federal Register.
III. Discussion of the Rule
This rule establishes a safety zone over all navigable waters within 200 yards radius of the current location of the Barge DEFIANT. The duration of the zone is intended to protect personnel, vessels, and the marine environment in these navigable waters while the Owning company of the vessel completes their salvage plan.
IV. 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
We have analyzed this rule under Executive Order 13132, Federalism, and have determined that it is consistent with the fundamental federalism principles and preemption requirements described in that Order.
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 ( printed page 7400) 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
As required by The Unfunded Mandates Reform Act of 1995 (2 U.S.C. 1531-1538), the Coast Guard certifies that this rule will not result in an annual expenditure of $100,000,000 or more (adjusted for inflation) by a State, local, or tribal government, in the aggregate, or by the private sector.
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 is a safety zone. It is categorically excluded from further review under paragraph L60(d) 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.
