Wyoming Regulatory Office

The Department of the Army Regulatory Program is one of the oldest in the Federal Government. Initially it served a fairly simple, straightforward purpose: to protect and maintain the navigable capacity of the nation's waters. Time, changing public needs, evolving policy, case law and new statutory mandates have changed the complexion of the program, adding to its breadth, complexity and authority.

The Regulatory Program is committed to protecting the Nation's aquatic resources, while allowing reasonable development through fair, flexible and balanced permit decisions. The Corps evaluates permit applications for essentially all construction activities in the Nation's waters, including wetlands.

Regulatory Announcement

 15 May 2024 – Permit applications are now available in RRS!


USACE is pleased to announce that the new national online application portal and management platform, known as the Regulatory Request System (RRS) now includes an electronic submission option for permit applications. This platform has been introduced to modernize our permit application process and to address our users' expectations by providing a straightforward and transparent process for the submittal of permit requests.

RRS is a web-based platform currently in a beta version that enables users to submit pre-application meeting requests, jurisdictional determination requests, and new applications for individual and general permits. This new system aims to streamline the process, improve efficiency, and provide a more user-friendly experience for our applicants.     

All six states in the Omaha District, which includes the northeastern quarter of Colorado, Nebraska, Montana, North Dakota, South Dakota, and Wyoming, are accepting RRS electronic submissions. Please note that in the state of Montana, the RRS joint permit application (JPA) process will not be available on May 15th.  The Montana Regulatory Offices will be flexible with incoming applications submitted in the RRS and continue to coordinate with state and federal counterparts to minimize the burden on applicants. The external JPA form for Montana’s resources is still available online; for further information regarding this JPA, please visit: https://dnrc.mt.gov/Licenses-and-Permits/Stream-Permitting/.

We believe that RRS will not only benefit our users by simplifying the application process but will also enhance our ability to effectively manage and review permit requests. We are confident that this modernization initiative will lead to improved customer satisfaction and greater overall efficiency within our Regulatory Program.

We encourage users to explore and utilize the new Regulatory Request System to take advantage of its benefits and features. Visit rrs.usace.army.mil today!

The U.S. Army Corps of Engineers (USACE) and EPA (the Agencies) jointly announce the availability of the Interim Draft of the National Ordinary High Water Mark Field Delineation Manual for Rivers and Streams (National OHWM Manual) and its accompanying data sheet. The Interim Draft National OHWM Manual provides draft technical guidance for identifying and delineating the OHWM using a scientifically supported, rapid framework. The Agencies are requesting comments and feedback from the public and practitioners on the Interim Draft of the National OHWM Manual via the public notice linked below. Following the public comment period and additional field testing, comments and feedback received from the public and practitioners will be utilized to further refine the Interim Draft of the National OHWM Manual for clarity, consistency, and technical accuracy. The one-year testing and comment period ends on December 1, 2023. A final version of the National OHWM Manual is anticipated to be published during 2024.

During the period while the OHWM Manual is an interim draft, OHWM identification and/or delineation for official USACE Regulatory purposes should continue in accordance with the applicable OHWM definition in the Federal regulations, Regulatory Guidance Letter 05-05, and any applicable USACE district policies. However, USACE Regulatory staff are encouraged to test the Interim Draft of the National OHWM Manual and provide comments and feedback by emailing usace.ohwm@usace.army.mil.
