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.

We Are Paperless

New requests for a pre-application meeting, jurisdictional determination, or permit should be submitted through the Regulatory Request System (RRS) at rrs.usace.army.mil.  You can also report a potential violation using the RRS.  Other requests will continue to be accepted in digital format through the Los Angeles District Regulatory contacts listed below.

After your request is received, a Regulatory Project Manager and identification number will be assigned.  For quicker service, you should submit any additional information or documentation for your request directly to the Regulatory Project Manager.

 

 

 

 

 

 

 

 

Note that RRS currently does not support entering multiple request types at a time (e.g., a combined JD request and permit application) as part of the same submittal for a project area. At this time, individual RRS submittals are required for each individual JD request, permit application, etc. that a user wishes to make.  Enter one request type; wait for a response from the Corps (which will include the assigned Project Manager and Department of the Army [DA] number); and then enter the next request type (be sure to include the DA number in the auto-generated email in the field provided ).

Recent News

5/8/25: Last year the U.S. Army Corps of Engineers introduced its new Regulatory Request System (RRS), an online application portal that allows the public to submit permit applications and other information when requesting permission to dredge, fill or conduct activities in jurisdictional wetlands and waters of the U.S. RRS is accessible at https://rrs.usace.army.mil/rrs. RRS users can submit individual permit applications, general permit pre-construction notifications, jurisdictional determination requests, and other information needed during the permit evaluation process using easy-to-follow online submission forms. Applicants can also track the status of their requests using a user-friendly dashboard. RRS benefits the applicant by eliminating the burden associated with the preparation and mailing of paper applications. It also reduces some of the effort associated with processing applications and data entry making the permitting process more efficient.

1/6/25: The U.S. Army Corps of Engineers (USACE) announces the launch of the Public Notice module on the Regulatory Request System (RRS). The new feature allows users nationwide to search, review, and comment on projects being reviewed under the Regulatory Program, significantly enhancing transparency, accessibility, and efficiency. The Public Notice module provides the public with access to proposed projects requiring a standard permit, proposed mitigation banks and in-lieu fee programs under review, and proposed general permits or Section 404 Letter of Permission procedures.  It organizes notices by state and district, which can be viewed in a table format or on an interactive map. Users can easily search for notices by project name or address and submit comments directly through the platform, streamlining public engagement and reinforcing USACE's commitment to improving transparency and the permitting process. The RRS is a web-based platform, currently in its beta version, designed to simplify the permitting process and enhance user experience. In addition to the new Public Notice Module, RRS enables users to submit permit applications, request jurisdictional determinations, and schedule pre-application meetings, all through a user-friendly interface.
