On June 18, 2026, the U.S. Coast Guard acted swiftly to impose a temporary emergency safety zone on a crucial stretch of the Ohio River near Madison, Indiana. This decisive measure was implemented in response to a downed powerline near mile marker (MM) 560.0, which posed an immediate and serious threat to navigation and public safety. The rule, codified as 33 CFR Part 165, took effect without prior notice and comment, underscoring the urgent nature of the hazard. It remains in force through June 25, 2026, or until the powerline is repaired and the danger is fully mitigated.
The Immediate Threat and Coast Guard's Response
The Captain of the Port (COTP) Ohio Valley, Captain Randy L. Preston, determined that the downed powerline created a significant safety concern. The primary dangers included the potential for electrical shock to anyone in the water or aboard vessels, as well as the presence of utility workers and equipment in the river while repairs are underway. Such circumstances necessitate immediate action to prevent accidents and protect lives. The Coast Guard received notification of the event on June 18, 2026, prompting the rapid establishment of the safety zone to protect life, vessels, and the marine environment in the navigable waters.
Operating under the authority granted by 46 U.S.C. 70034, which empowers the Coast Guard to establish safety zones for navigable waters, the agency invoked emergency rulemaking procedures. Specifically, the Coast Guard cited 5 U.S.C. 553(b)(B) and 5 U.S.C. 553(d)(3), which allow for the waiver of public notice and comment periods when good cause exists. In this case, the need to prevent vessels and persons from coming into contact with the dangerous downed powerline, and the lack of time to solicit public input, formed the basis for this expedited process.
Scope and Enforcement of the Safety Zone
The emergency safety zone encompasses all navigable waters on the Ohio River from mile marker 559.0 to mile marker 561.0, extending from the surface to the bottom. During the enforcement period, which began on June 18, 2026, and is scheduled to conclude on June 25, 2026, or earlier if repairs are completed, entry into this designated area is strictly prohibited. The only exception is for vessels or persons who have received specific authorization from the Captain of the Port Ohio Valley or their designated representative. Designated representatives may include Coast Guard patrol commanders, coxswains, petty officers, or other federal, state, and local officers assisting the COTP in enforcement.
Those needing to seek permission to enter the zone must contact the COTP or their representative via VHF-FM channel 16 or by telephone. Compliance with all lawful orders and directions from the COTP or designated representatives is mandatory for anyone within the safety zone.
Broader Regulatory Context
Even in emergency rulemaking, federal agencies must consider various regulatory analyses. The Coast Guard's assessment of this temporary final rule indicated that the Regulatory Flexibility Act of 1980, concerning impacts on small entities, does not apply because the rule was issued without prior notice and comment. Similarly, the rule was found not to impose new information collection requirements under the Paperwork Reduction Act. From a federalism perspective, the rule is consistent with Executive Order 13132 and poses no tribal implications under Executive Order 13175. Furthermore, the action does not trigger the Unfunded Mandates Reform Act of 1995, as it will not result in expenditures exceeding $100 million annually.
Environmentally, the Coast Guard determined that this emergency safety zone, lasting seven days and prohibiting entry within a two-mile stretch of the Ohio River, is categorically excluded from further review under the National Environmental Policy Act of 1969. A Record of Environmental Consideration supporting this determination is available for public review.
Implications for Waterway Users and Safety
This emergency declaration serves as a stark reminder of the dynamic nature of waterway safety and the critical role of agencies like the Coast Guard in responding to unforeseen hazards. While temporary, such zones can disrupt commercial and recreational navigation, highlighting the importance of real-time communication and adherence to maritime regulations. The swift invocation of emergency powers demonstrates a commitment to preventing potential tragedies, prioritizing human life and environmental protection over procedural timelines when immediate threats emerge.
