A years-long legal battle is heating up again between the state of Michigan and Line 5 pipeline operator Enbridge Inc., with the state taking legal action on Nov. 13 aimed at shutting down the line in 180 days. The twin pipeline carries light crude oil and natural gas liquids beneath the Straits of Mackinac.
Canada-based Enbridge says it will fight the state’s revocation of an easement granted 67 years ago that allows for extension of the 4-mile pipeline through the straits that connect Lake Michigan and Lake Huron.
