Section 408 Permissions

This site describes the process for review and approval of all requests to modify, alter, or occupy any existing U.S. Army Corps of Engineers-constructed public works project.  Public works projects include dams, basins, levees, channels, navigational channels, and any other local flood protection works constructed by the Corps.  In order for the District to approve any proposed alterations requests, it must meet Corps’ standards, and must not be injurious to the public interest or affect the USACE project’s ability to meet its authorized purpose.

Obtain a Section 408 Permission

The processing of a Section 408 Permission request begins with a written request from an applicant.  The permission application (SPL Form 25) should be completed, along with the other documents as required in each Checklist.  Each request for an alteration will be evaluated on a case-by-case basis.  All application packages will be screened for completeness before they are filed in the District.  A request for additional information may be sent to notify you of any additional information which may be necessary for the Corps to review your proposed project.  If an application is complete we will notify you with the identification number.

Once sufficient information is provided, it is the responsibility of the Corps’ Section 408 Program Manager, supported by the Project Delivery Team technical staff, to evaluate proposed alterations.  The proposal will be evaluated for impacts of the proposed alteration to flood conveyance, structural integrity, operation and maintenance, NEPA requirements, and flood fighting capabilities as well as meeting Corps policy and criteria.  Upon completion of the review, the Applicant is notified whether the proposal is approved or denied.

EC 1165-2-220 provides the policies and procedural guidance that the District follows in processing requests to alter or modify civil works projects that were constructed by the Corps of Engineers.

Upon permission approval, the permittee is responsible for the construction oversight to ensure construction is in accordance with the plans and specifications approved by USACE.  After construction completion, notification is provided to the USACE that all permitted construction is complete and final documentation submitted.

Permit applicants an send up to 25 files per package, up to 8 GB, Files greater than 8 GB can be compressed (zip, 7z, tar.gz, etc.) to reduce the size of the file. It is suggested that the permit applicant compress each of the 5 folders separately (a-General, b-Technical, c-O&M, d-RE, e-Environmental) separately. Please make sure to notify the 408 permit coordinator after any drop-offs have been made as they will have 7 days to access the files.

General.  The sole authority to grant permission for temporary or permanent alterations is contained in Section 14 of the Rivers and Harbors Act of 1899 and codified in 33 USC 408 (Section 408).  Approval for any modifications, alterations, or occupation of public works projects is granted through the District’s Section 408 program.  The District Engineer has the authority to approve most relatively minor, low impact alterations/modifications to the public works facilities however, some requests which involve significant modifications, raisings, realignments, etc. may need to be approved at Corps Headquarters.

Applications for modifications to completed projects can be submitted from a number of sources.  Most federally-constructed public works projects are turned over to a Non-Federal project sponsor for operation and maintenance.  Anyone wishing to modify one of these facilities should first contact the Non-Federal Sponsor and work with them to prepare the permission application for submission to the Corps for review and approval.  Once the Corps approves the modification / alteration, a permission will be issued to that Non-Federal Sponsor, who in turn would issue their own permit to the Applicant.

Applications for permission to perform new construction affecting flood-control reservoirs and channels for which the Federal Government holds rights-of-way and Operations and Maintenance responsibility, are referred directly to the Corps of Engineers.  The permission would then be issued directly to the Applicant.
