The state has awarded permits to Enbridge Energy to dig the tunnel that would house a new Line 5 pipeline. The replacement would still be used to move petroleum products on a path that runs beneath environmentally sensitive Straits of Mackinac.

Hugh McDiarmid of the Michigan Department of Environment, Great Lakes and Energy says this decision does not address the wisdom of an oil pipeline in the Great Lakes, but technical issues with digging the tunnel.

A judge has ordered Enbridge Energy to shut down a set of twin pipelines that run through the Straits of Mackinac.
                That’s in response to a request filed by state Attorney General Dana Nessel.

The Michigan Court of Appeals has upheld a law that allows Enbridge Energy to build a tunnel so it can continue to move oil and natural gas liquids through a controversial Great Lakes pipeline.

Line Five runs beneath the Straits of Mackinac, which connects Lake Michigan and Lake Huron.
