WALLA WALLA DISTRICT REGULATORY DIVISION
Published Jan. 9, 2026
PRINT | E-MAIL

On January 8, 2026, the U.S. Army Corps of Engineers (Corps) published a final action in the Federal Register (91 FR 768) announcing the reissuance of 56 existing nationwide permits (NWPs) and one new NWP, as well as the reissuance of NWP general conditions and definitions with some modifications. These 57 NWPs will go into effect on March 15, 2026, and will expire on March 15, 2031. One NWP was not reissued. The Corps has also issued final decision documents for the new and reissued NWPs. These final decision documents are available at www.regulations.gov at docket number COE-2025-0002. Furthermore, the national NWP decision documents will be supplemented by Division Engineers to address decisions concerning the addition of regional conditions to the NWPs.

EXPIRATION OF 2021 NWPs: The 56 existing NWPs published in the January 8, 2026, final action replace the 2021 versions of these NWPs. The 2021 versions of these NWPs expire on March 14, 2026.

REGIONAL CONDITIONS: With the publication of this Federal Register notice, Corps divisions will begin finalizing regional conditions for these 57 NWPs. Regional conditions will provide additional protection for the aquatic environment and will help ensure that the NWPs authorized only those activities with no more than minimal adverse environmental effects. Regional conditions will help ensure protection of high value waters within Idaho.

Corps divisions and districts will also begin determining which conditions for water quality certifications issued by states, tribes, and EPA for the issuance of these NWPs become conditions of these NWPs. Corps divisions and districts will also begin determining which conditions for Coastal Zone Management Act consistency concurrences issued by states for the issuance of these NWPs become conditions of these NWPs. Those regional conditions will be announced in a future public notice issued by the Walla Walla District.
