Waters of the United States

EPA and Army Finalize Rule Establishing Definition of WOTUS and Restoring Fundamental Water Protections

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.
