Waters of the United States

  • EPA and Army Announce Process to Submit Nomination Letters for Regional Roundtables

    EPA and Army are announcing a process for stakeholders to submit nomination letters with a slate of participants to potentially be selected as one of ten roundtables on the regional implications of “waters of the United States” (WOTUS). The regional roundtables will engage stakeholders representing diverse perspectives in meaningful dialogue to help inform the agencies’ work to develop an enduring definition of WOTUS that supports public health, environmental protection, agricultural activity, and economic growth.

    In response to robust interest in these regional roundtables, the agencies have extended the deadline for submissions to December 1, 2021.

    More information about the roundtables and additional stakeholder engagement opportunities can be found here.

  • Order Vacating and Remanding the Navigable Waters Protection Rule

    The Environmental Protection Agency and U.S. Army Corps of Engineers (the agencies) are in receipt of the U.S. District Court for the District of Arizona’s August 30, 2021, order vacating and remanding the Navigable Waters Protection Rule in the case of Pascua Yaqui Tribe v. U.S. Environmental Protection Agency. In light of this order, the agencies have halted implementation of the Navigable Waters Protection Rule and are interpreting “waters of the United States” consistent with the pre-2015 regulatory regime until further notice. The agencies continue to review the order and consider next steps. This includes working expeditiously to move forward with the rulemakings announced on June 9, 2021, in order to better protect our nation’s vital water resources that support public health, environmental protection, agricultural activity, and economic growth. The agencies remain committed to crafting a durable definition of “waters of the United States” that is informed by diverse perspectives and based on an inclusive foundation.
