On December 4, 2018, the Vessel Incidental Discharge Act (VIDA) was signed into law establishing a new framework for the regulation of discharges incidental to the normal operation of vessels. Under the VIDA, the Environmental Protection Agency (EPA) is responsible for developing national performance standards for discharges from primarily commercial vessels greater than 79 feet in length, and for ballast water from small vessels less than 79 feet in length and fishing vessels. In 2019, EPA consulted with states and Tribes to meaningful and timely input into the development of the proposed rule. Based on EPA’s review of the proposed rule and comments received during the first public comment period and subsequent meetings with interested states, tribes, and other stakeholders, on October 18, 2023, EPA’s Supplemental Notice of Proposed Rulemaking was published in the Federal Register. Comments on the Supplemental Notice must be received no later than December 18, 2023.
