Credit Lester Graham / Michigan Radio If Line 5 is still pumping petroleum through the Straits of Mackinac on Thursday, Michigan Governor Gretchen Whitmer has notified Enbridge Energy, she will consider all resulting profits to be property of the state of Michigan. That notice, contained in a letter Whitmer and Department of Natural Resources Director Dan Eichinger wrote Tuesday to Enbridge Executive Vice President Vern Yu, offers the first glimpse into Whitmer’s planned response if the Canadian oil giant follows through with a vow to defy state orders to shut down the pipeline. It comes as Enbridge is also taking fire from the Bay Mills Indian Community, whose executive council has voted to officially banish Line 5 from its territory — a legal action that is considered a punishment of last resort in tribal law. The tribe is calling upon the federal government to enforce the banishment as part of its legal obligation to protect tribal treaty rights to hunt, fish and gather in ceded territory including the Straits of Mackinac.
