USACE launches new Regulatory Request System

The U.S. Army Corps of Engineers Regulatory Program has launched its beta version of the national Regulatory Request System, or RRS. During the initial phases of the RRS rollout, our regulatory process in the St. Paul District remains unchanged. We will be collaborating closely with our state permitting agencies and will continue to keep the public informed of any changes in permit application procedures that may arise during the RRS rollout.

In Minnesota and Wisconsin, the public can test the Regulatory Request System (RRS) by requesting pre-application meetings and permit-related jurisdictional determinations. Please do not use the RRS to apply for a permit in Minnesota or Wisconsin. The St. Paul District employs a joint permit application process with those states. We will continue to process all requests received through our statewide electronic mailboxes or obtained from state agencies. Please go to the following link for information on how to obtain a permit:

The St. Paul District Regulatory Program strongly encourages pre-application meetings, where regulatory team members can provide valuable advice to permit applicants to help streamline the permit process. We will also continue to prepare jurisdictional determinations that result in reducing, expediting, or eliminating permit requirements. Our regulatory project managers will continue to actively identify non-jurisdictional waters on project sites and prepare jurisdictional determinations to eliminate permit requirements on those waters. We are generally unable to divert resources from permitting activities to prepare jurisdictional determinations where there is no project proposal. This approach supports timely permit decisions and ensures we meet the public's needs effectively.

We appreciate your cooperation as we strive to enhance and streamline our regulatory processes for the benefit of all stakeholders. If you have questions specific to the St. Paul District’s use of the RRS, please contact 651-290-5358. For additional information on or to provide feedback on RRS, please contact us using the following email:

2022 National Wetland Plant List

The U.S. Army Corps of Engineers, as part of an interagency effort with the U.S. Environmental Protection Agency, the U.S. Fish and Wildlife Service, and the U.S. Department of Agriculture Natural Resources Conservation Service, is announcing the availability of the final 2022 National Wetland Plant List (NWPL). The Federal Register Notice for the 2022 NWPL update can be found here:

The NWPL provides plant species wetland indicator status ratings, which are used in determining whether the hydrophytic vegetation factor is met when conducting wetland delineations under the Clean Water Act and wetland determinations under the Wetland Conservation Provisions of the Food Security Act. Other applications of the NWPL include wetland restoration, establishment, and enhancement projects. The list is effective as of 13 February 2024 and will be used in any wetland delineations performed after this date. A summary of the 2022 NWPL is provided in the table below.

Open spaces in Washington County are increasingly developed and Hugo is experiencing high development growth over the last few years presenting a need for wetland credits in this region. The sponsor states the proposed bank is in a high impact area that would benefit from enhanced water quality controls and biological diversity in a fragmented system.

The USACE Regulatory Program - Importance to the Public

About Our Regulatory & Permits Office

The purpose of Corps of Engineers' regulatory program is to protect the nation's aquatic resources, while allowing reasonable development through fair, flexible and balanced permit decisions. The Corps evaluates permit applications for all regulated activities that occur in the nation's waters, including wetlands.

The Corps' regulatory program includes Section 10 of the Rivers and Harbors Act of 1899 and Section 404 of the Clean Water Act. The St. Paul District's regulatory jurisdiction covers the states of Minnesota and Wisconsin.

Under Section 10, a Corps permit is required to do any work in, over or under a 'Navigable Water of the U.S.' Waterbodies have been designated as 'Navigable Waters of the U.S.' based on their past, present or potential use for transportation for interstate commerce.

Under Section 404, a Corps permit is required for the discharge of dredged or fill material into waters of the U.S. Many waterbodies and wetlands in the nation are waters of the U.S. and are subject to the Corps' Section 404 regulatory authority.
