Enbridge- Reports for November 2017 Agreement with the State of Michigan


In November of last year, 2017, Enbridge and the State of Michigan entered into an agreement, setting forward a plan to improve coordination between the company and the State for the operation and maintenance of Enbridge’s Line 5 pipeline, while providing enhanced transparency to the citizens of Michigan. The agreement required Enbridge to produce four reports that looked at various aspects of Line 5 in the Straits of Mackinac and across Michigan.
