On December 30, 2022, the agencies announced the final "Revised Definition of 'Waters of the United States'" rule which will be effective 60 days after it is published in the Federal Register. The agencies developed this rule with consideration of the relevant provisions of the Clean Water Act and the statute as a whole, relevant Supreme Court case law, and the agencies’ technical expertise after more than 45 years of implementing the longstanding pre-2015 “waters of the United States” framework. This rule also considers the best available science and extensive public comment to establish a definition of “waters of the United States” that supports public health, environmental protection, agricultural activity, and economic growth. More information about the final rule is available below.
