II. Background and Authority

The Coast Guard received notification that the Chicago Triathlon will be taking place within a small area of Monroe Harbor on Lake Michigan in Chicago, IL. The Captain of the Port (COTP) Lake Michigan has determined that a safety zone is needed to protect personnel, vessels, and the marine environment in the navigable waters of Lake Michigan while this event is taking place. Therefore, the COTP Lake Michigan 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.

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. The Coast Guard only recently received final details for the Chicago Triathlon swim event on July 23, 2026. It is impracticable to publish an NPRM because we must establish this safety zone by August 23, 2026.

For the same reason, 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 temporary safety zone from 6 a.m. through 10:30 a.m. on August 23, 2026. The area will be bounded by the following points in Monroe Harbor in Lake Michigan in Chicago, IL, beginning at 41°52.787′ N, 087°36.988′ W, then east to 41°52.786′ N, 087°36.962′ W, then southeast to 41°52.594′ N, 087°36.815′ W, then south to 41°52.515′ N, 087°36.816′ W, then south to 41°52.135′ N, 087°36.896′ W, then west to 41°52.134′ N, 087°36.974′ W returning to the point of origin. No vessels or person will be permitted to enter the safety zone without obtaining permission from the COTP Lake Michigan or a designated representative.

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