  • RGP-2302-RWY

    Expiration date: 6/21/2023

    The U.S. Army Corps of Engineers (Corps), Omaha District proposes to issue Regional General Permit (RGP) 2302 for discharges of dredged or fill material into irrigation ditches and wetlands that have minimal individual or cumulative adverse effects on the aquatic environment but that do not qualify for the Clean Water Act section 404(f)(1)(C) exemption because of the recapture provision at section 404(f)(2) (see 33 CFR 323.4) or do not qualify for a Nationwide General permit. This permit is applicable to all jurisdictional waters of the United States within the State of Wyoming including, but not limited to, rivers, creeks, ditches, lakes, ponds, reservoirs, and wetlands. Certain waterways and aquatic resource types are given special consideration. The Corps proposes to reissue this RGP for a period of five (5) years. The purpose of this public notice is to inform the public, Indian Tribes, Federal, state and local agencies/officials, and other interested parties of a 21-day comment period in which written comments may be submitted to the Corps. Written comments must be postmarked by June 21, 2023 prior to closure of the public notice administrative record.

  • Notice of Availability of the Beta Streamflow Duration Assessment Method for the Great Plains

    Expiration date: 9/28/2023

    The U.S. Army Corps of Engineers (Corps) Albuquerque, Chicago, Detroit, Fort Worth, Galveston, Kansas City, Omaha, Rock Island, St. Louis, St. Paul, and Tulsa Districts, and the U.S. Environmental Protection Agency (EPA), Regions 5, 6, 7, and 8, jointly announce the availability of the Beta Streamflow Duration Assessment Method (SDAM) for the Great Plains (dated September 2022). The method is a rapid assessment tool to help distinguish between ephemeral, intermittent, and perennial streamflow at the reach scale for the Northern and Southern Great Plains SDAM Regions. The beta SDAM may help provide technical guidance for identifying waters that may be subject to regulatory jurisdiction under Section 404 of the Clean Water Act; however, this method does not alter or change the definition of “Waters of the U.S.”


    Expiration date: 7/27/2022

    The U.S. Army Corps of Engineers, Omaha District, (Corps) is issuing this public notice to inform members of the public of Section 404 of the Clean Water Act (Section 404) and Section 10 of the Rivers and Harbors Act of 1899 (Section 10). The Corps administers the permitting process for activities in waters of the United States and when activities occur over, in, or under a Section 10 water. This public notice explains when the Corps has jurisdiction over work or activities, what types of Department of Army (DA) permits are available, and how to apply for those permits. Specific emphasis is on emergencies and the permitting process for emergency activities in Montana and Wyoming. An “emergency” is a situation which would result in an unacceptable hazard to life, a significant loss of property, or an immediate, unforeseen, and significant economic hardship if corrective action requiring a permit is not undertaken within a time period less than the normal time needed to process the application under standard procedures. See 33 CFR 325.2(e)(4).
