Public Notices

  • Electronic Submittals

    The Montana Regulatory Office of the U.S. Army Corps of Engineers' Omaha District has been working to be more responsive to the needs of the public. For the Regulatory Program, we know there is great interest in allowing information associated with aquatic resource delineation verifications, permit applications, pre-application meetings, and other requests in a digital format, instead of paper. To that end, we have created a process for the public to submit their requests electronically. This new process is easy to access, ensures timely delivery, improves efficiency, reduces costs and environmental footprint, and comports with Army and Department of Defense (DoD) requirements.

  • Special Public Notice for Federal Register Notice

    Expiration date: 3/18/2022

    On January 6, 2017, the U.S. Army Corps of Engineers (Corps) published the notice in the Federal Register announcing the reissuance of all existing nationwide permits (NWPs), general conditions, and definitions with some modifications. The NWPs became effective on March 19, 2017, and will expire on March 18, 2022.

  • 2017 Nationwide Permit Reissuance and Montana Regional Conditions

    Expiration date: 3/18/2022

    On January 6, 2017, the U.S. Army Corps of Engineers (Corps) published the notice in the Federal Register announcing the reissuance of all 50 existing nationwide permits (NWPs), general conditions, and definitions with some modifications. The Corps also issued two new NWPs, one new general condition, and five new definitions. The 2017 NWPs will go into effect on March 19, 2017, and will expire on March 18, 2022. After publication of the FR notice, Corps districts finished development of regional conditions for the reissued NWPs. Regional conditions provide additional protection by ensuring that NWPs authorize only those activities with minimal adverse effects on the aquatic environment. Regional conditions also help ensure protection of high value waters within specific geographic areas. By this public notice the Northwestern Division Engineer establishes the enclosed regional conditions applicable to the NWP program in Montana.
