Enbridge Submitted a Joint Application for Line 5 Tunnel
(Houston, TX) Enbridge Energy wants to build a roughly 4-mile-long tunnel beneath the Straits of Mackinac. It would replace the underwater segment of Line 5, a pipeline that runs between Superior, Wisconsin, and Sarnia, Ontario.
Enbridge submitted a joint application to the Michigan Department of Environment, Great Lakes and Energy and the U.S. Army Corps of Engineers. Approval from both is needed for the project to go forward.
