DEPARTMENT OF HOMELAND SECURITY

Coast Guard

33 CFR Part 165

[Docket Number USCG-2025-0259]
RIN 1625-AA00


Safety Zone; Straits of Mackinac, Mackinaw City, MI

AGENCY: Coast Guard, DHS.

ACTION: Notice of proposed rulemaking.

-----------------------------------------------------------------------

SUMMARY: The Coast Guard is proposing to establish a temporary safety 
zone for navigable waters within a 100-yard radius of the center span 
of the Mackinac Bridge, Straits of Mackinac, Mackinaw City, MI. The 
safety zone is needed to protect personnel, vessels, and the marine 
environment from a marine event involving swimmers under the bridge. 
This proposed rulemaking would prohibit persons and vessels from being 
in the safety zone unless authorized by the Captain of the Port Sector 
Northern Great Lakes or a designated representative. We invite your 
comments on this proposed rulemaking.

DATES: Comments and related material must be received by the Coast 
Guard on or before June 2, 2025.

ADDRESSES: You may submit comments identified by docket number USCG-
2025-0259 using the Federal Decision-Making Portal at https://www.regulations.gov. See the ``Public Participation and Request for 
Comments'' portion of the SUPPLEMENTARY INFORMATION section for further 
instructions on submitting comments. This notice of proposed rulemaking 
with its plain-language, 100-word-or-less proposed rule summary will be 
available in this same docket.

FOR FURTHER INFORMATION CONTACT: If you have questions about this 
proposed rulemaking, call or email LT Rebecca Simpson, Sector Northern 
Great Lakes Waterways Management Division, U.S. Coast Guard; 906-635-
3223, email [email protected].

II. Background, Purpose, and Legal Basis

    On September 17, 2024, an organization notified the Coast Guard 
that it will be conducting a swim within a 100-yard radius of the 
Mackinac Bridge from 7 a.m. to noon on July 26, 2025. Approximately 400 
swimmers will swim from Mackinaw City to St. Ignace on the east side of 
the bridge. The Captain of the Port Sector Northern Great Lakes (COTP) 
has determined that potential hazards associated with the swim would be 
a safety concern for anyone within a 100-yard radius of the bridge.
    The purpose of this rulemaking is to ensure the safety of vessels 
and the navigable waters within a 100-yard radius of the bridge before, 
during, and after the scheduled event. The Coast Guard is proposing 
this rulemaking under authority in 46 U.S.C. 70034.

III. Discussion of Proposed Rule

    This rule establishes a safety zone from 7 a.m. until noon on July 
26, 2025. The safety zone will cover all navigable waters within 100 
yards of the Mackinac Bridge while swimmers are beneath it. The 
duration of the zone is intended to protect personnel and vessels in 
these navigable waters while swimmers are in the water. No vessel or 
person will be permitted to enter the safety zone without obtaining 
permission from the COTP or a designated representative. The regulatory 
text we are proposing appears at the end of this document.

IV. Regulatory Analyses

    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.

A. Regulatory Planning and Review

    Executive Orders 12866 and 13563 direct agencies to assess the 
costs and benefits of available regulatory alternatives and, if 
regulation is necessary, to select regulatory approaches that maximize 
net benefits. This NPRM has not been designated a ``significant 
regulatory action'' under section 3(f) of Executive Order 12866. 
Accordingly, the NPRM has not been reviewed by the Office of Management 
and Budget (OMB).
    This regulatory action determination is based on the size, 
location, duration, and time-of-day for the safety zone. Vessel traffic 
will be able to safely transit around all safety zones which will 
impact small designated areas within the COTP zone for short durations 
of time. Moreover, the Coast Guard will issue Broadcast Notice to 
Mariners via VHF channel 16 about the zone and the rule allows vessels 
to seek permission to enter the zone.

B. Impact on Small Entities

    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.
    While some owners or operators of vessels intending to transit the 
safety zone may be small entities, for the reasons stated in section 
IV.A above, this proposed rule would not have a significant economic 
impact on any vessel owner or operator.
    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 rule would economically affect it.
    Under section 213(a) of the Small Business Regulatory Enforcement 
Fairness Act of 1996 (Pub. L. 104-121), we want to assist small 
entities in understanding this proposed rule. If the proposed rule 
would affect your small business, organization, or governmental 
jurisdiction and you have questions concerning its provisions or 
options for compliance, please call or email the person listed in the 
FOR FURTHER INFORMATION CONTACT section. The Coast Guard will not 
retaliate against small entities that question or complain about this 
proposed rule or any policy or action of the Coast Guard.

C. Collection of Information

    This proposed rule would not call for a new collection of 
information under the Paperwork Reduction Act of 1995 (44 U.S.C. 3501-
3520).

D. 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 proposed 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 proposed rule does not have Tribal implications under 
Executive Order 13175 (Consultation and Coordination with Indian Tribal 
Governments) because it would 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. If 
you believe this proposed rule has implications for federalism or 
Indian Tribes, please call or email the person listed in the FOR 
FURTHER INFORMATION CONTACT section.

E. 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 proposed rule would not 
result in such an expenditure, we do discuss the potential effects of 
this proposed rule elsewhere in this preamble.

F. Environment

    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 made 
a preliminary determination 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 involves a safety 
zone lasting 5 hours that would prohibit entry within 100 yards of the 
center span of the bridge. Normally such actions are 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 preliminary 
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. We seek any comments or 
information that may lead to the discovery of a significant 
environmental impact from this proposed rule.
