The Environmental Protection Agency and the U.S. Department of the Army (agencies) are in receipt of the U.S. Supreme Court's May 25, 2023, decision in the case of Sackett v. Environmental Protection Agency. In light of this decision, the agencies are interpreting the phrase “waters of the United States” consistent with the Supreme Court’s decision in Sackett. The agencies are developing a rule to amend the final "Revised Definition of 'Waters of the United States'" rule, published in the Federal Register on January 18, 2023, consistent with the U.S. Supreme Court’s May 25, 2023 decision in the case of Sackett v. Environmental Protection Agency. The agencies intend to issue a final rule by September 1, 2023.
