Department of Transportation

Great Lakes St. Lawrence Seaway Development Corporation

1. 33 CFR Part 401
2. RIN 2135-AA59

AGENCY:

Great Lakes St. Lawrence Seaway Development Corporation, DOT.

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 SLSMC, 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 March 17, 2026.

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 Operations Office; U.S. Department of Transportation, 1200 New Jersey Avenue SE, Suite W58-213, ( printed page 12691) Washington, DC 20590, between 9 a.m. and 5 p.m., Monday through Friday, except Federal holidays.

FOR FURTHER INFORMATION CONTACT:

Donna O'Berry, Chief Counsel, Great Lakes St. Lawrence Seaway Development Corporation, 1200 New Jersey Ave. SE, Washington, DC 20590; (202) 366-6136.

SUPPLEMENTARY INFORMATION:

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 SLSMC, 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, Dangerous Cargo, Toll Assessment and Payment, and Information and Reports. 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 2026 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, 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

I certify 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

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

Unfunded Mandates

GLS 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.

List of Subjects in 33 CFR Part 401

• Hazardous materials transportation
• Navigation (water)
