The EPA and the Department of the Army intend to engage with State and Tribal co-regulators; industry and agricultural stakeholders; environmental and conservation stakeholders; and the public on certain key topics related to the implementation of the definition of "waters of the United States" in light of the Supreme Court's 2023 decision in Sackett v. Environmental Protection Agency. This notice includes an announcement of forthcoming listening sessions on specific key topic areas to hear interested stakeholders' perspectives on defining "waters of the United States" consistent with the Supreme Court's interpretation of the scope of Clean Water Act jurisdiction and how to implement that interpretation as the agencies consider next steps. The agencies are also accepting written recommendations from members of the public via a recommendations docket. These opportunities are intended to provide for broad, transparent engagement with a full spectrum of stakeholders. Written recommendations must be received on or before 23 April 2025.
