A federal judge on Wednesday blocked Michigan Governor Gretchen Whitmer‘s attempt to shut down the Line 5 oil pipeline, which runs under the Straits of Mackinac connecting Lake Michigan and Lake Huron. The ruling asserts that only the federal government has authority in regulating interstate pipeline safety.
The judge's opinion followed Whitmer's 2020 order for regulators to revoke Enbridge Inc.'s easement, citing fears of catastrophic spills from the 72-year-old pipeline. Enbridge subsequently filed a federal lawsuit to contest this order.
U.S. District Judge Robert Jonker pointed out that revoking the easement would effectively mean shutting down Line 5. He referenced the Pipeline Safety Act of 1992, which explicitly prevents states from regulating interstate pipeline safety. Jonker acknowledged Michigan's concerns regarding environmental risks but noted that the federal government has prioritized interstate pipeline issues over state authority.
Enbridge welcomed the ruling, stating it protects against significant energy disruptions for both the United States and Canada. The case has broader implications as other legal challenges concerning Line 5 are ongoing, including actions by Michigan Attorney General Dana Nessel and various environmental groups.
The pipeline continues to be a contentious issue, with environmental advocates warning that an oil spill in the Great Lakes would cause devastating consequences. Legislative battles continue as the U.S. Supreme Court weighs in on whether a related case belongs in state or federal court.
