This bill, titled the "Soo Locks Security and Economic Reporting Act of 2025," directs the Secretary of Transportation, in coordination with the Commandant of the Coast Guard and the Secretary of Defense, to submit a comprehensive report to Congress within one year. The report's primary objective is to assess the security vulnerabilities of the Soo Locks in Sault Ste. Marie, Michigan, and to analyze the potential supply chain, logistical, and economic consequences that would arise from a malfunction or failure of these critical locks, impacting both the region and the United States. Specifically, the report must highlight existing security deficiencies, identify potential domestic or international threats, and detail the current security structures of relevant federal, state, and local agencies. It will also provide specific recommendations, including cost estimates, for strengthening the overall security of the Soo Locks. Additionally, the report will propose strategies to effectively reduce the adverse impacts on the United States' supply chain in the event of an operational disruption.
