  • 30 July 2021 – EPA and Army Announce Next Steps for Crafting Enduring Definition of Waters of the United States

    The Environmental Protection Agency (EPA) and the Department of the Army (Army) have announced plans for upcoming community engagements to inform their efforts to revise the definition of “waters of the United States” (WOTUS). EPA and Army have stated a commitment to developing a reasonable, effective, and durable definition of WOTUS that protects public health, the environment, and downstream communities while supporting economic opportunity, agriculture, and other industries.

    EPA and Army are announcing a series of engagement opportunities, including an opportunity for stakeholders and the public to provide written recommendations and a series of public meetings in August to hear perspectives on the rulemaking. In addition, the agencies are initiating Federalism and Tribal consultations for the foundational rule. The agencies also intend to host a series of dialogues with state and Tribal co-regulators this fall to discuss both rulemakings.

  • 9 June 2021 - EPA, Army Announce Intent to Revise Definition of Waters of the United States
    The Environmental Protection Agency and Department of the Army have announced their intent to revise the definition of “waters of the United States” to better protect our nation’s vital water resources that support public health, environmental protection, agricultural activity, and economic growth.

    After reviewing the Navigable Waters Protection Rule as directed by President Biden, the EPA and Department of the Army have determined that this rule is leading to significant, permanent environmental degradation,” said EPA Administrator Michael S. Regan. “We are committed to establishing a durable definition of ‘waters of the United States’ based on Supreme Court precedent and drawing from the lessons learned from the current and previous regulations, as well as input from a wide array of stakeholders, so we can better protect our nation’s waters, foster economic growth, and support thriving communities.

    Together, the Department of the Army and EPA will develop a rule that is informed by our technical expertise, is straightforward to implement by our agencies and our state and Tribal co-regulators, and is shaped by the lived experience of local communities” said Acting Assistant Secretary of the Army for Civil Works Jaime A. Pinkham.

    The agencies’ new regulatory effort will be guided by the following considerations:

    - Protecting water resources and our communities consistent with the Clean Water Act.
    - The latest science and the effects of climate change on our waters.
    - Emphasizing a rule with a practical implementation approach for state and Tribal partners.
    - Reflecting the experience of and input received from landowners, the agricultural community that fuels and feeds the world, states, Tribes, local governments, community organizations, environmental groups, and disadvantaged communities with environmental justice concerns.

    The agencies are committed to meaningful stakeholder engagement to ensure that a revised definition of waters of the United States considers essential clean water protections, as well as how the use of water supports key economic sectors. Further details of the agencies’ plans, including opportunity for public participation, will be conveyed in a forthcoming action.

  • 28 Jan 2020 - NRCS and Army rescind 2005 joint memorandum The Natural Resources Conservation Service (NRCS) and the Deputy Assistant Secretary of the Army have provided written notice to rescind the 2005 joint memorandum titled "Guidance on Conduction Wetland Determinations for the Food Security Act of 1985 and Section 404 of the Clean Water Act".  This rescission is effective immediately. This rescission does not alter the roles or responsibilities of the Agencies under their respective statutory and regulatory authorities. The Agencies will continue their practice of informing landowners that wetland delineations (performed by the Corps) and determinations (performed by the NRCS) may not be valid for FSA or CWA requirements, respectively.  The Agencies intend to issue new guidance on this topic in the near future.
