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. 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 specifically
authorized by the Captain of the Port, Sector Northern Great Lakes. We
invite your comments on this proposed rulemaking.
DATES: Comments and related material must be received by the Coast
Guard on or before June 4, 2026.

U.S.C. United States Code
II. Background and Authority
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 18, 2026. 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. Therefore, the COTP
is proposing 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 regulatory text we are
proposing appears at the end of this document.
III. Discussion of the Rule
This proposed rule would establish a safety zone from 7 a.m. until
noon on July 18, 2026. The safety zone would cover all navigable waters
within 100 yards of the Mackinac Bridge while swimmers are beneath it.
No vessel or person would be permitted to enter the safety zone without
obtaining permission from the COTP or their designated representative.
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. 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. Section 605 of the RFA allows an agency to certify a rule, in
lieu of preparing an analysis, if the rulemaking is not expected to
have a significant economic impact on a substantial number of small
entities. 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.
Vessel traffic will be able to safely transit around this regulated
area. This regulation will only impact a small area for a few hours. In
addition, the Coast Guard will issue a Broadcast Notice to Marines via
VHF FM marine channel 16, which will allow small entities to adjust
their transit plans, and the rule allows 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).
B. Collection of Information
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).
C. Federalism and Indian Tribal Governments
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.
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 proposed 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 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 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 proposed 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.
