Jan 13, 2021 TRAVERSE CITY — Enbridge said Tuesday it would defy Michigan’s demand to shut down an oil pipeline that runs through a channel linking two of the Great Lakes, contending that Gov. Gretchen Whitmer’s decision was based on bad information and political posturing. The Democratic governor in November moved to revoke a 1953 state easement that allowed part of the Canadian company’s Line 5 to be placed along the bottom of the Straits of Mackinac. Saying Enbridge had repeatedly violated the terms and put the lakes at risk, Whitmer gave the company 180 days — until May 12 — to turn off the flow.
