Coast Guard, Department of Homeland Security.
Notice of proposed rulemaking.
The Coast Guard is proposing to update special local regulations (SLR) for certain navigable waters of the Milwaukee River. The SLR update is needed to make the regulations more accurate and to continue to protect personnel, vessels, and the marine environment from potential hazards created by a boat race. This proposed rulemaking would delete an outdated SLR for the Milwaukee Open Water Swim and update the Milwaukee River Challenge to change the date from "1 day; the third Saturday of September." to "1 day; on or around early October." We invite your comments on this proposed rulemaking.
Comments and related material must be received by the Coast Guard on or before January 16, 2026.
To submit comments and view available documents, go to the Federal Docket Management System at https://www.regulations.gov and search for USCG-2025-0936.
If you have questions about this proposed rule, contact LCDR Lynn Schrayshuen, Sector Lake Michigan Waterways Management Division, U.S. Coast Guard; telephone 414-378-0111, or email [email protected].

NPRM Notice of proposed rulemaking
§ Section
U.S.C. United States Code
On September 24, 2025, the Coast Guard met with the event sponsors for the Milwaukee River Challenge and confirmed that their event, which is in its 24th year, will occur annually on or around the beginning of October due to reduced conflict with recreational and commercial vessels during that timeframe. The Captain of the Port Sector Lake Michigan (COTP) is proposing to update the Special Local Regulations in Table 1 to 33 CFR 100.903 for recurring marine events in the COTP Zone to reflect this change and to eliminate outdated regulations. The COTP is proposing these updates under the authority in 46 U.S.C. 70041 and 33 CFR 1.05-1, as they are needed to protect personnel, vessels, and the marine environment in the navigable waters within the regulated area. The regulatory text we are proposing appears at the end of this document.
This proposed rule would update the date for an established special regulated area in Table 1 to 33 CFR 100.903, the Milwaukee River Challenge, from "1 day; the third Saturday of September." to "1 day; on or around early October." The event title and the location of the regulated area would remain the same. No vessel or person would be permitted to enter the regulated area without obtaining permission from the COTP or their designated representative. The proposed rule also would delete the Milwaukee Open Water Swim from the regulatory text in Table 1 (currently Item 6), as this event no longer occurs. The regulatory text we are proposing appears at the end of this document.
We developed this proposed 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.
The Regulatory Flexibility Act of 1980, 5 U.S.C. 601-612, as amended, requires Federal agencies to consider the potential impact of regulations on small entities during rulemaking. 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. The Coast Guard certifies under 5 U.S.C. 605(b) that this proposed rule would not have a significant economic impact on a substantial number of small entities for the following reasons.
This regulation would only impact the Milwaukee River for less than 8 hours. The enforcement period would be during a time when vessel traffic is normally low. In addition, the Coast Guard would issue a Broadcast Notice to Marines via VHF FM marine channel 16, which would allow small entities to adjust their transit plans, and the rule would allow vessels to request permission to enter the regulated area from the COTP.
If you think that your business, organization, or governmental jurisdiction qualifies as a small entity and that this proposed rule would have a significant economic impact on it, please submit a comment (see ADDRESSES ) explaining why you think it qualifies and how and to what degree this proposed rule would economically affect it.
Under section 213(a) of the Small Business Regulatory Enforcement Fairness Act of 1996 (Pub. L. 104-121), if this proposed 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).
This proposed rule will not call for a new collection of information under the Paperwork Reduction Act of 1995 (44 U.S.C. 3501-3520).
We have analyzed this proposed 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 proposed 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.
As required by The Unfunded Mandates Reform Act of 1995 (2 U.S.C. 1531-1538), the Coast Guard certifies that this proposed rule would 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.
We have analyzed this proposed 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 proposed rule is an update to a special regulated area. It is categorically excluded from further review under paragraph L61.
