Preferred route selection process

Enbridge developed the Project’s preferred route based on its extensive pipeline routing experience, knowledge of applicable federal and state regulations, and agency, landowner and other input.

Preferred Route Selection Handout

Enbridge first considered where the Project must enter, deliver within, and exit Minnesota in order to meet the needs of shippers served by Line 3. Enbridge next identified and analyzed routing constraints and opportunities, and identified and analyzed route alternatives.

Once a general route location was identified, Enbridge conducted detailed environmental and engineering survey work to further refine the route to avoid or minimize human and environmental impacts, as well as identify appropriate mitigation measures to limit potential impacts during Project construction and operation. The resulting preferred route meets the Project’s purpose, maximizes opportunities for colocating within a utility corridor, and minimizes potential impacts.
