Coast Guard Implements Temporary Safety Zone on Detroit River for Rowing Regatta

The U.S. Coast Guard has implemented a temporary special local regulation for a segment of the Detroit River to ensure public safety during an upcoming rowing regatta. This measure, effective on June 27, 2026, from 7 a.m. to 4 p.m., will restrict vessel and personnel movement within the regulated area between Point Hennepin and the Grosse Ile toll bridge in the Trenton Channel. The action aims at mitigating potential hazards associated with the large-scale marine event.

Event Context and Safety Rationale

This regulation stems from a request by the Wyandotte Boat Club, which plans to host a rowing regatta involving approximately 400 participants. The Captain of the Port (COTP) Detroit determined that the scale of the event presents significant safety concerns. These include increased vessel congestion, the inherent tipping hazards of competitive rowing shells, and the risks associated with cold-water recovery in the event of an accident. The primary purpose of this rule is to protect all individuals on the water, both participants and non-participants, and to safeguard the marine environment during the event.

Scope of the Special Local Regulation

The temporary rule establishes a regulated area covering all navigable waters of the Detroit River, specifically the Trenton Channel, from surface to bottom and shoreline to shoreline, between Point Hennepin and the Grosse Ile toll bridge. During the nine-hour enforcement period on June 27, 2026, non-participants are strictly prohibited from entering, transiting, or anchoring within this designated zone. Any vessel or person seeking to enter the area must obtain explicit permission from the COTP Detroit or their designated representative. These representatives will be monitoring VHF-FM channel 16 for such requests. Designated representatives include Coast Guard personnel as well as Federal, State, and local officers assisting in enforcement.

Expedited Rulemaking and Legal Basis

A notable aspect of this regulation is its implementation as a temporary final rule without prior public notice and comment. The Coast Guard justified this expedited process by invoking the "good cause" exception under the Administrative Procedure Act. Specifically, 5 U.S.C. 553(b)(B) was cited. The agency stated that it was "impracticable" to conduct a Notice of Proposed Rulemaking (NPRM) because the SLR needed to be in effect by June 27, 2026, to protect personnel and vessels. This left insufficient time to solicit and respond to comments. Similarly, the rule was made effective less than 30 days after publication, citing good cause under 5 U.S.C. 553(d)(3) for the same urgency. This approach is common for temporary safety measures that address immediate or time-sensitive risks on federal waterways.

Wider Regulatory Compliance and Analysis

Despite the expedited nature of its implementation, the Coast Guard performed various regulatory analyses. The agency determined that the rule would not impose significant economic impacts on small entities. This allowed for the waiver of the Regulatory Flexibility Act analysis. It also found no new collection of information requirements under the Paperwork Reduction Act. Furthermore, the rule was determined to have no substantial direct effect on Indian tribal governments under Executive Order 13175. It also was found to have no unfunded mandates exceeding $100 million annually under the Unfunded Mandates Reform Act. Environmentally, the rule was categorically excluded from further review under the National Environmental Policy Act (NEPA). This exclusion was due to its nature as a special local regulation, indicating it does not individually or cumulatively have a significant effect on the human environment.
