Michigan officials approved a $500 million plan Friday to encase in a protective tunnel a portion of an oil pipeline that runs beneath a channel connecting two Great Lakes, leaving just one more regulatory hurdle for the contentious project.
The state's three-person Public Service Commission approved the project in the Straits of Mackinac on a 2-0 vote. Commissioner Alessandra Carreon abstained, noting she just joined the commission four months ago.
