Regulatory Mission

The Department of the Army Regulatory Program is one of the oldest in the federal government. Initially, it served a fairly simple purpose: to protect and maintain the navigable capacity of the nation's waters. Changing public needs, evolving policy, court decisions, and new statutory mandates have changed several aspects of the program, including its breadth, complexity and authority.

The Regulatory Program administers and enforces Section 10 of the Rivers and Harbors Act of 1899; Section 404 of the Clean Water Act of 1972, as amended; and Section 103 of the Marine Protection, Research, and Sanctuaries Act of 1972.  Under Section 10 of the Rivers and Harbors Act, a Corps permit is required for work or structures in, over, or under navigable waters of the United States.  Under Section 404 of the Clean Water Act, a Corps permit is required for the discharge of dredged or fill material into waters of the United States.  Many waterbodies and wetlands in the nation are waters of the United States and are subject to the Corps' Section 404 regulatory authority.  Under Section 103 of the Marine Protection, Research, and Sanctuaries Act, the Corps regulates the transport and disposal of dredged material at designated ocean sites.

All Corps permit decisions are subject to various other Federal laws applicable to Federal actions, such as the Endangered Species Act, the National Historic Preservation Act, and the Magnuson-Stevens Fisheries Conservation and Management Act.

2/13/24:  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: https://www.govinfo.gov/content/pkg/FR-2024-02-13/pdf/2024-02903.pdf. 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.

1/31/24:  USACE announces the launch of its new Regulatory Request System (RRS). RRS is designed to make the review of permit requests a transparent and efficient process for the public. 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 in Spring 2024. 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. 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: rrs.usace.army.mil. For additional information on or to provide feedback on RRS, please contact rrs@usace.army.mil.

9/8/23:  The U.S. Environmental Protection Agency (EPA) and Department of the Army (the agencies) issued a final rule to amend the final “Revised Definition of ‘Waters of the United States’” rule, published in the Federal Register on January 18, 2023. This final rule conforms the definition of “waters of the United States” to the U.S. Supreme Court’s May 25, 2023, decision in the case of Sackett v. Environmental Protection Agency. Parts of the January 2023 Rule are invalid under the Supreme Court’s interpretation of the Clean Water Act in the Sackett decision. Therefore, the agencies have amended key aspects of the regulatory text to conform it to the Court’s decision. The conforming rule, "Revised Definition of 'Waters of the United States'; Conforming," was published in the Federal Register and became effective September 8, 2023.

4/21/23:  On April 20, 2023, the U.S. Court of Appeals for the Sixth Circuit temporarily issued a stay of enforcement of the 2023 Rule until May 10, 2023 in Commonwealth of Kentucky v. EPA (No. 23-5343) and Kentucky Chamber of Commerce, et al. v. EPA (No. 23-5345). In light of this stay, the agencies interpret "waters of the United States" consistent with the pre-2015 regulatory regime inside the Commonwealth of Kentucky and for the Commonwealth and Plaintiff-Appellants in Case No. 23-5345 and their members until May 10, 2023.

3/20/23:  On March 19, 2023, a district court judge for the Southern District of Texas issued an order preliminarily enjoining in Idaho and Texas the 2023 Rule issued by EPA and the Department of the Army defining “waters of the United States.” On April 12, 2023, a district court judge in North Dakota issued an order preliminarily enjoining in 24 States the 2023 rule issued by EPA and the Department of the Army defining “waters of the United States.” These States include Alabama, Alaska, Arkansas, Florida, Georgia, Iowa, Indiana, Kansas, Louisiana, Mississippi, Missouri, Montana, Nebraska, New Hampshire, North Dakota, Ohio, Oklahoma, South Carolina, South Dakota, Tennessee, Utah, Virginia, West Virginia, and Wyoming. The agencies are reviewing the decisions and their options.
