Army Corps Fast-Tracks Line 5 Tunnel Review

On Wednesday, April 16, 2025, the U.S. Army Corps of Engineers decided to fast-track permits for building a protective tunnel around the Enbridge oil pipeline that runs beneath a channel connecting two Great Lakes. Obtaining these permits is one of the final steps in securing Line 5. The move comes after President Donald Trump issued an executive order in January declaring that the U.S. has become too dependent on foreign energy sources and mandates that federal agencies identify energy infrastructure projects for expedited emergency permitting from the U.S. Army Corps of Engineers and the Environmental Protection Agency. NPGA, MPGA and WPGA have supported litigation supporting Line 5.
