U.S. Army Corps of Engineers accepts comments on Enbridge Line 3 replacement project

Published Dec. 20, 2018

ST. PAUL, Minn. – The U.S. Army Corps of Engineers, St. Paul District, announced today the beginning of a public comment period for the Enbridge Line 3 replacement project. St. Paul District is currently evaluating a permit request for construction-related activities affecting water resources associated with the proposed Enbridge Line 3 replacement crude oil pipeline. A public notice announcing the comment period can be found at:

The Corps has regulatory authority under Section 404 of the Clean Water Act and under Sections 10 and 14 of the Rivers and Harbors Act. The Corps regulates placement of fill material in wetlands and other waters, as well as work and structures in navigable waters. The Corps does not regulate the overall construction or operation of pipelines, nor does it regulate the siting of any type of pipeline or any substance being transported within a pipeline. The Corps is one of several permitting agencies to review the project.

The proposed project involves the replacement of pipeline across 80 miles of wetlands in Minnesota and approximately 1-mile in North Dakota. The proposed project will result in temporary impacts to approximately 1,000 acres of wetlands, and permanent impacts to 10 acres of wetlands. The project requires crossing 211 water bodies, approximately half of which are ditches.

Public comments may be submitted from Dec. 20, 2018, to Jan. 21, 2019, by email to​, or mailed to:
