What is Section 408?

Section 408 is the process that allows alteration to a federally authorized project. The proposed project cannot pose a risk to the public interest and will not impair the usefulness of the federally authorized project. Examples of federally authorized projects include, but are not limited to levees, dams and the federal navigation channel.

This requirement was established in Section 14 of the Rivers and Harbors Act of 1899, codified at 33 United States Code (USC) 408 (Section 408).

15-Day Notice                    

This Public Notice announces the Section 408 review of the ODOT US30 Graham Creek. 

Portland District is reviewing the ODOT US30 Graham Creek project which proposes replace aging and undersized culverts near the Magruder-Graham Creek Levee segment within the Magruder Levee System in Clatskanie, Oregon. The project is intended to improve fish passage as well as replace aging and undersized culverts along a portion of Graham Creek, of the Columbia River Highway (US30) in Clatskanie, Oregon 

Alteration of a federally authorized project: This proposed project would temporarily modify a federal flood protection system (levee) and therefore require authorization from the Corps, pursuant to 33 USC 408 (Section 408). Section 408 provides authority to the Secretary of the Army to grant permission for the alteration or modification of Corps federal civil works projects when, in the judgment of the Secretary, such alteration or modification will not be injurious to the public interest and will not impair the usefulness of the project.

Consideration of Comments: The Corps is soliciting comments specific to this project from the public, federal, state and local agencies and officials, and other interested parties. Comments will be considered in determining whether it would be in the public interest to proceed with this action.

All comments received will become part of the official record and are subject to public release under the Freedom of Information Act including any personally identifiable information such as names, phone numbers, and addresses.
Comments: Interested parties may submit, in writing, any comments directed specifically to this proposal and not to other regulatory processes administered by the Corps or other government agencies pertaining to the ODOT US30 Graham Creek Project
