Ahead of a public hearing, we review the latest on the Line 5 tunnel project

The proposal to bury oil and natural gas liquid pipelines beneath the Straits of Mackinac has been a lightning rod for years. A virtual hearing on a state permit is set for Thursday.

But there are lots of moving parts: state permits, federal permits, legal challenges and more.

IPR's Vivian La listened in on a state meeting last week and is preparing for the EGLE hearing on Thursday. We thought it would be useful to walk through some of the details.

Permitting

  • This Thursday, The Michigan Department of Environment, Great Lakes, and Energy (EGLE) will hold a virtual public hearing on a pending pollutant discharge permit
  • Awaiting a decision from EGLE for a wetlands permit
  • Awaiting a decision from the U.S. Army Corps of Engineers on a federal permit

Legal fights

  • The existential question of whether Line 5 belongs in the Straits will be heard in state court, per a U.S. Supreme Court decision in April
  • Gov. Gretchen Whitmer is appealing a U.S. Sixth Circuit Court of Appeals decision that ruled for Enbridge on a matter of federal pipeline regulation

Stakes for Tribal Nations

  • Tribes in Michigan are challenging a permit for the tunnel project from the Michigan Public Service Commission. A decision from the Michigan Supreme Court is expected this summer.
  • Tribes in Wisconsin are challenging a project to reroute a segment of Line 5 that runs through Tribal land.

This post will be updated with more information.
