On December 30, 2022, the agencies announced the final "Revised Definition of 'Waters of the United States'" rule. On January 18, 2023, the rule was published in the Federal Register; the rule will be effective on March 20, 2023. The agencies’ final rule establishes a clear and reasonable definition of “waters of the United States” and reduces the uncertainty from constantly changing regulatory definitions that has harmed communities and our nation’s waters.
These roundtables allowed stakeholders to engage and discuss their experiences with implementing the definition of "waters of the United States," including challenges and opportunities within their geographic areas.
