Event Summary

On July 15, 2026, the United States — Michigan Department of Environment, Great Lakes, and Energy (EGLE) reissued a wetlands permit for Enbridge's Great Lakes Tunnel Project, and the United States — Wisconsin Department of Natural Resources (DNR) granted a permit related to impacts on rare plants and animals. The permits are necessary for constructing a 4-mile tunnel beneath the Straits of Mackinac to house a new segment of the Line 5 oil pipeline. The approvals follow a 16-month review and over 70,000 public comments. Environmental groups and some politicians criticized the decision, while supporters cited energy reliability and jobs. Litigation over the pipeline's future continues at state and federal levels.
