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.

06/22/2020: The Environmental Protection Agency (EPA) and the Department of the Army’s Navigable Waters Protection Rule: Definition of “Waters of the United States” (NWPR) became effective in 49 states and in all US territories.  (A preliminary injunction is effective for the State of Colorado only.)  NWPR establishes the scope of federal regulatory authority under the Clean Water Act.  The NWPR includes four simple categories of jurisdictional waters and provides specific exclusions for many water features that traditionally have not been regulated.  Additional information about the NWPR can be found on the EPA’s website at https://www.epa.gov/nwpr.  Information on jurisdiction can also be found at https://www.usace.army.mil/Missions/Civil-Works/Regulatory-Program-and-Permits/juris_info/.

05/21/2020: The U.S. Army Corps of Engineers (Corps), as part of an interagency effort with the U.S. Environmental Protection Agency (EPA), the U.S. Fish and Wildlife Service (FWS) and the U.S. Department of Agriculture Natural Resources Conservation Service (NRCS), is announcing the availability of the final 2018 National Wetland Plant List (NWPL).  The Federal Register Notice for the 2018 NWPL update can be found here: https://www.govinfo.gov/content/pkg/FR-2020-05-18/pdf/2020-10630.pdf.

The NWPL provides plant species 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 May 18, 2020 and will be used in any wetland delineations performed after this date.  Completed wetland delineation/determination forms should reference the version of the NWPL used to complete the form.  The final NWPL is available at http://wetland-plants.usace.army.mil/. State, regional, and national lists can also be downloaded from this site.
