Tribes, environmental groups challenge Michigan's approval of Line 5 tunnel project

Tribal nations and environmental organizations are pushing back against Michigan’s approval of a tunnel project for the Line 5 pipeline under the Straits of Mackinac. The groups argue that the Michigan Public Service Commission (MPSC) failed to consider the potential climate change impacts and alternatives to the project. They contend the approval overlooks the environmental risks, including possible oil spills, and ignores the concerns of Indigenous communities whose lands and waters could be affected. Legal proceedings are ongoing, with the Michigan Court of Appeals reviewing the case.
