Summary

The Great Lakes St. Lawrence Seaway Development Corporation (GLS) is amending joint regulations with Canada to update various categories within the Seaway Regulations and Rules. These changes aim to clarify existing requirements for users of the Seaway.

What changed

The Great Lakes St. Lawrence Seaway Development Corporation (GLS), in conjunction with Canada's St. Lawrence Seaway Management Corporation (SLSMC), is issuing a final rule to amend the joint Seaway Regulations and Rules. The updates affect sections on Condition of Vessels, Seaway Navigation, Radio Communications, Dangerous Cargo, Information and Reports, and General provisions. The primary purpose of these amendments is to clarify existing requirements for commercial users of the Seaway.

This rule is effective January 10, 2025, and is intended to align with Canadian regulations and ensure consistency for Seaway users prior to the opening of the Seaway season. While the GLS certifies that the rule will not have a significant economic impact on small entities, primarily due to the foreign vessel operator majority, commercial users should review the updated regulations to ensure compliance with the clarified requirements.

What to do next

  1. Review updated Seaway Regulations and Rules sections including Condition of Vessels, Seaway Navigation, Radio Communications, Dangerous Cargo, Information and Reports, and General.

ACTION:

Final rule.

SUMMARY:

The Great Lakes St. Lawrence Seaway Development Corporation (GLS) and the St. Lawrence Seaway Management Corporation (SLSMC)
of Canada, under international agreement, jointly publish and presently administer the St. Lawrence Seaway Regulations and
Rules (Practices and Procedures in Canada) in their respective jurisdictions. Under agreement with the SLSMC, the GLS is amending
the joint regulations by updating the regulations and rules in various categories. These changes are to clarify existing requirements
in the regulations.

DATES:

This rule is effective on January 10, 2025.

ADDRESSES:

Docket: For access to the docket to read background documents or comments received, go to https://www.regulations.gov; or in person at the Docket Management Facility; U.S. Department of Transportation, 1200 New Jersey Avenue SE, West Building
Ground Floor, Room W12-140, Washington, DC 20590-001, between 9 a.m. and 5 p.m., Monday through Friday, except Federal holidays.

Carrie Mann Lavigne, Chief Counsel, Great Lakes St. Lawrence Seaway Development Corporation, 180 Andrews Street, Massena,
New York 13662; (315) 764-3200.

SUPPLEMENTARY INFORMATION:

The GLS and SLSMC of Canada, under international agreement, jointly publish and presently administer the St. Lawrence Seaway
Regulations and Rules (Practices and Procedures in Canada) in their respective jurisdictions. Under agreement with the SLSMC,
the GLS is amending the joint regulations by updating the Regulations and Rules in various categories. The changes update
the following sections of the Regulations and Rules: Condition of Vessels, Seaway Navigation, Radio Communications, Dangerous
Cargo, Information and Reports, and General. These changes are to clarify existing requirements in the regulations.

Regulatory Notices: Privacy Act: Anyone is able to search the electronic form of all comments received into any of our dockets by the name of the individual
submitting the comment (or signing the comment, if submitted on behalf of an association, business, labor union, etc.). You
may review DOT's complete Privacy Act Statement in the
Federal Register
published on April 11, 2000 (65 FR 19477-78) or you may visit https://www.regulations.gov.

The joint regulations will become effective in Canada in 2025 prior to the opening of the Seaway. For consistency, because
these are joint regulations under international agreement, and to avoid confusion among users of the Seaway, the GLS finds
that there is good cause to make the U.S. version of the amendments effective upon the date of publication to ensure an effective
date prior to the Seaway opening.

Regulatory Evaluation

This regulation involves a foreign affairs function of the United States and therefore, Executive Order 12866 does not apply
and evaluation under the Department of Transportation's Regulatory Policies and Procedures is not required.

Regulatory Flexibility Act Determination

The GLS certifies that this regulation will not have a significant economic impact on a substantial number of small entities.
The St. Lawrence Seaway Regulations and Rules primarily relate to commercial users of the Seaway, the vast majority of whom
are foreign vessel operators. Therefore, any resulting costs will be borne mostly by foreign vessels.

Environmental Impact

This regulation does not require an environmental impact statement under the National Environmental Policy Act (49 U.S.C.
4321, et seq.) because it is not a major Federal action significantly affecting the quality of the human environment.

Federalism

The Corporation has analyzed this rule under the principles and criteria in Executive Order 13132, dated August 4, 1999, and
has determined that this rule does not have sufficient federalism implications to warrant a Federalism Assessment.

Unfunded Mandates

The Corporation has analyzed this rule under title II of the Unfunded Mandates Reform Act of 1995 (Pub. L. 104-4, 109 Stat.
48) and determined that it does not impose unfunded mandates on State, local, and Tribal governments and the private sector
requiring a written statement of economic and regulatory alternatives.

Paperwork Reduction Act

This regulation has been analyzed under the Paperwork Reduction Act of 1995 and does not contain new or modified information
collection requirements subject to the Office of Management and Budget review.
