MI environmental groups, Tribes decry fast-tracking Line 5 tunnel
April 18, 2025
Environmental groups across Michigan are pushing back after the U.S. Army Corps of Engineers confirmed it will fast-track Enbridge’s Line 5 tunnel project without conducting a full environmental review.
Line 5 is a 645-mile pipeline transporting crude oil and natural gas liquids beneath the Straits of Mackinac. Speeding up the project is a response to President Donald Trump’s declaration of a “national energy emergency.”
Ashley Rudzinski, climate and environment program director at the nonprofit Groundwork Center for Resilient Communities, alleged fast-tracking Line 5 without a thorough review violates at least two state laws, the Michigan Public Trust Law and the Submerged Land Act, and raises concerns about potential oil spills and threats to treaty rights.
“We have also seen many of our partners in this work, and allies – the six Tribal nations here in Michigan – pull out of continued negotiations with the Army Corps,” Rudzinski pointed out. “In my estimation, that is because this process has become a sham.”
Enbridge responded in a statement saying in part, “Line 5 is critical energy infrastructure” and it is safe. It went on to say Michigan approved environmental permits and tunnel placement but after nearly five years, the project still awaits a U.S. Army Corps decision on its environmental impact.
Critics of the Line 5 tunnel are urging Gov. Gretchen Whitmer and the Michigan Department of Environment, Great Lakes and Energy to deny the necessary permits.
Rudzinski warned the project may also become a burden on taxpayers.
“Enbridge has petitioned the Federal Energy Regulatory Commission to be able to pass the tunnel construction cost onto their shippers, who ultimately can pass that on to consumers,” Rudzinski noted. “That means everyday folks will have to pay more for these products.”
Enbridge has consistently stated it will bear the full financial responsibility for the construction, operation and maintenance of the Line 5 tunnel, and taxpayers will not be required to fund any part of the project.
