Over the last few years, Michigan officials have been at odds with the company Enbridge, who owns and operates Line 5 -- a major oil pipeline that runs beneath the Straits of Mackinac. AdOn Friday, March 12, the Michigan Public Service Commission introduced the state’s new Propane Security Plan. Though the closure of Line 5 appears to be a “when” issue for Michigan officials, Enbridge officials in January said they have no intention of closing the pipeline. AdOn Nov. 24, 2020, Enbridge filed a federal lawsuit against the state of Michigan, challenging the state’s attempt to revoke the 1953 easement. Enbridge officials argued that shutting down Line 5 is “improper and unlawful,” and that disrupting the oil flow would negatively impact U.S. and Canadian residents and businesses.
