Final Rule: Definition of “Waters of the United States” Addition of Applicability Date to 2015 Clean Water Rule

The Environmental Protection Agency and U.S. Department of the Army (the agencies) finalized a rule adding an applicability date to the 2015 Rule defining “waters of the United States.” The final rule published in the Federal Register on February 6, 2018. The 2015 Rule will not be applicable until February 6, 2020. This amendment gives the agencies the time needed to reconsider the definition of “waters of the United States.”
