Final Conforming Rule and Updated Definition of "Waters of the United States" Outreach

On August 29, 2023, the U.S. Environmental Protection Agency and Department of the Army ("the agencies") issued a final rule to amend the final “Revised Definition of ‘Waters of the United States’” rule, published in the Federal Register on January 18, 2023. This final rule conforms the definition of “waters of the United States” to the U.S. Supreme Court’s May 25, 2023, decision in the case of Sackett v. Environmental Protection Agency. Parts of the January 2023 Rule are invalid under the Supreme Court’s interpretation of the Clean Water Act in the Sackett decision. Therefore, the agencies have amended key aspects of the regulatory text to conform it to the Court’s decision. The conforming rule, "Revised Definition of 'Waters of the United States'; Conforming," published in the Federal Register and became effective on September 8, 2023. Read more about the conforming rule. 

Listening Sessions

The agencies have committed to hosting virtual listening sessions focused on identifying issues that may arise outside the September 2023 rule to conform the definition of “waters of the United States” to the decision in Sackett. The agencies hosted multiple listening sessions in February 2024 to enable broad participation from co-regulators and stakeholders. The listening sessions were recorded, and the links to the recordings are listed below. 

Update Webinars

On November 15 and 16, 2023, the agencies hosted two Tribal and state webinars to provide updates on the definition of "waters of the United States." Both webinars presented the same information. The agencies also hosted three public webinars to provide updates on the definition of “waters of the United States” on September 12, 13, and 20, 2023. The agencies are also posting a presentation dated September 24, 2024, that provides the most up-to-date information to the public regarding where the amended 2023 rule is operative across the country in light of ongoing litigation. The webinars are posted below. 

Final January 2023 Rule Outreach

The final "Revised Definition of 'Waters of the United States'" rule was published in the Federal Register on January 18, 2023, and the rule took effect on March 20, 2023. The January 2023 Rule is amended by the conforming rule, "Revised Definition of 'Waters of the United States'; Conforming," that published in the Federal Register and became effective on September 8, 2023. Please visit the Rule Status page for additional information about the status of the January 2023 Rule, as amended, and litigation.

Regional Roundtables on Implementation of "Waters of the United States" Rules
