Enbridge plans to continue to operate its Line 5 oil pipeline under the Great Lakes' Straits of Mackinac, in defiance of Michigan Gov. Gretchen Whitmer's order to shut down the system over repeated violations of the terms of a 1953 state easement. "The governor's notice is actually based on inaccurate and outdated information that ignores the current condition of the dual pipelines," said Enbridge Vice President of US operations Mike Koby, calling Whitmer's decision biased and political.
