Line 5

In separate cases heard in back-to-back hearings by the Supreme Court, the plaintiffs argued the state has never fully analyzed the risks posed by a more than 70-year-old section of pipeline located in the Straits of Mackinac.

The U.S. Supreme Court heard arguments on Tuesday about whether state or federal court will have the final say on the future of the controversial Line 5 pipeline. Vivian La breaks down the ruling.

Michigan has been trying to shut down the controversial pipeline since 2019. A technical question before the court could seal its fate.

Public comments are due by the end of the week after the U.S. Army Corps of Engineers proposed a tunnel alternative last month.

Weeks before an anticipated final Line 5 permitting decision, environmentalists say the federal government is pulling a 'bait-and-switch' in the Straits of Mackinac.

The state’s highest court will reconsider the Michigan Court of Appeals’ decision in favor of the permit back in February.

The National Wildlife Federation says Michigan's environment department should fully review what damage drilling the tunnel for a new pipeline segment might cause.

The review is a major step toward a permitting decision on the controversial proposal to build a tunnel underneath the Straits of Mackinac. The last day for the public to comment is June 30.

The U.S. Army Corps of Engineers reviewed the environmental effects of constructing a tunnel, leaving the existing lines as they are or covering the dual lines with gravel and rock.

The clock will start on public comment at the end of May, but with half as much time — 30 days instead of 60.
