II. Background and Authority

The Coast Guard received notification of an ongoing sewage leak in the vicinity of the Florida Avenue Bridge at position 29°58.860 N, 90°.01.300 W. The Captain of the Port (COTP) New Orleans has determined that potential hazards associated with the sewage leak are a safety concern for anyone transiting within MM 6.5 East of Harvey Lock to MM 10 East of Harvey Lock along the Gulf Intracoastal Waterway (GIWW) which includes the Inner Harbor Navigational Canal (IHNC) Lock. These hazards include exposure to harmful substances and the presence of response vessels and personnel working in the area.

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. The COTP previously established a safety zone for this response on April 18, 2026. The effective date for that temporary rule has expired but the response is continuing, therefore the COTP is issuing this temporary rule to extend the effective period of the safety zone.

Because of these potential hazards, the Coast Guard is issuing this rule without prior notice and comment. As is authorized by 5 U.S.C. 553(b)(B), the Coast Guard finds that good cause exists for not publishing a notice of proposed rulemaking (NPRM) with respect to this rule because it is impracticable and contrary to the public interest. Additionally, the Coast Guard was notified of this event on April 18, 2026, and issued a temporary safety zone rule that expired May 2, 2026. However, we must issue this temporary rule immediately due to continuing response operations, to extend enforcement of the previously established safety zone until May 22, 2026, to continue to protect personnel, vessels, and the marine environment. Therefore, we do not have enough time to solicit and respond to comments.

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 from May 5, 2026 through May 22, 2026. The safety zone will cover all navigable waters within MM 6.5 East of Harvey Lock to MM 10 East of Harvey Lock along the Gulf Intracoastal Waterway (GIWW) which includes the Inner Harbor Navigational Canal (IHNC) Lock. Vessels and persons will not be allowed to enter the zone during this time, unless authorized by the COTP. The COTP will also issue public advisories to notify the public of the safety zone location and enforcement schedule.

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 ( printed page 27205) 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

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 et seq.), 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.

For the reasons discussed in the preamble, the Coast Guard amends 33 CFR part 165 as follows:
