1625-AD02 202504 Unified Agenda of Federal Regulatory and Deregulatory Actions 1625 U.S. Coast Guard USCG 1600 Department of Homeland Security DHS Coast Guard-National Transportation Safety Board Marine Casualty Investigations: Major Marine Casualty Property Value Threshold

The Coast Guard and the National Transportation Safety Board (NTSB) jointly propose to amend the monetary property damage threshold amount for reporting a major marine casualty. The current amount no longer accurately reflects the level of significance for a major marine casualty that would justify an independent investigation by the NTSB. Additionally, this change would standardize the definition of a major marine casualty throughout the Code of Federal Regulations, eliminating confusion for the public and regulators caused by multiple definitions for the term.
