U.S. Army Corps of Engineers, Department of the Army, DoD.

Pursuant to the National Environmental Policy Act (NEPA) of 1969, as amended, the U.S. Army Corps of Engineers, Portland District (USACE) intends to prepare a Supplemental Environmental Impact Statement (SEIS) to address the directive in the 2024 Water Resources Development Act (WRDA) to formally analyze an alternative that would cease hydropower operations at USACE owned and operated Willamette Valley Projects. The Willamette Valley System (WVS) must operate for its Congressionally authorized project purposes while complying with all applicable laws, including the Endangered Species Act (ESA), to avoid jeopardizing the continued existence of listed species. The USACE will serve as the lead Federal agency for the SEIS.

The USACE invites Federal and State agencies, Native American Tribes, local governments, interested parties, and the public to submit comments on development of the scope of the SEIS by June 6, 2025.

Send written scoping comments to U.S. Army Corps of Engineers, Portland District, P.O. Box 2946, Attn: CENWP-PME-E, Portland, OR 97208-2946. Email comments or requests to be added to the mailing list to: [email protected]. All comments and materials received, including names and addresses, will become part of the administrative record and may be released to the public.
