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 will remain 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.

Additional features will be added to the RRS this spring.  Before implementing any changes, we will work with state permitting agencies to determine which features will enhance public service in Minnesota and Wisconsin.

At this time, the public may test the RRS to request pre-application meetings or jurisdictional determinations. However, we will continue to process all requests received through our statewide electronic mailboxes or obtained from state agencies.

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: Jarrett Cellini by email at

USACE Regulatory Announcement
USACE launches new Regulatory Request System

Published Jan. 31, 2024

USACE announces the launch of its new Regulatory Request System, or RRS. The RRS is designed to make the review of permit requests a transparent and efficient process for the public. The RRS, currently in a beta version, provides general information on the regulatory program and allows the public to submit pre-application meeting requests and jurisdictional determination requests.

Additional capability is scheduled this spring. This added capability will allow users the ability to electronically submit individual and general permit applications and other necessary information, saving time and reducing the need for paper-based submissions.

The RRS will streamline the permit application process and underscores USACE commitment to modernizing our application process, meeting user expectations, and providing a transparent, straightforward process for the timely review of permit requests.

Stay tuned for further updates on the full release of the RRS. Please click on the following link to access RRS:

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.

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.
