Enbridge Line 5 is back up and running after protestors broke into a valve site.

The operator of a Michigan oil pipeline says it temporarily shut down Line 5 after protesters warned Enbridge that they planned to turn an emergency valve.

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.

MACKINAC COUNTY, Mich. – There was praise and disappointment on Friday after the Michigan Department Environment, Great Lakes and Energy approved the first permits to for the controversial tunnel project around the Enbridge Line 5 gas line. The dual oil pipeline is among the largest in the region and runs directly through the Mackinac Straits carrying 23 million gallons of crude oil each day. In 2010, a separate Enbridge pipeline spilled more than 800,000 gallons of oil into Talmadge Creek and the Kalamazoo River. AdEnvironmental scientists estimate an oil spill in the Straits of Mackinac would cost almost $2 billion in cleaning costs and lost tourism revenue. This week the Canadian Consul General in Detroit telling the Canadian National Post shutting down Line 5 could harm Canadian-U.S. relations.

Enbridge Inc. is suing the state of Michigan for taking steps to shut down the company’s oil pipeline that runs under the Straits of Mackinac. Gretchen Whitmer notified Enbridge that the state was revoking an easement granted in 1953 that allowed an extension of the Line 5 oil pipeline to run through the Straits of Mackinac. We remain highly committed to protecting the Great Lakes, the environment, and all the people who use these waters while delivering energy that people rely on daily. “They have repeatedly violated the terms of the 1953 easement by ignoring structural problems that put our Great Lakes and our families at risk. Today’s lawsuit filed by Enbridge brazenly defies the people of Michigan and their right to protect the Great Lakes from a catastrophic oil spill.

Gretchen Whitmer took legal action Friday to shut down a pipeline that carries oil beneath a channel linking two of the Great Lakes. "They have repeatedly violated the terms of the 1953 easement by ignoring structural problems that put our Great Lakes and our families at risk. The pipeline moves about 23 million gallons (87 million liters) daily between Superior, Wisconsin, and Sarnia, Ontario, traversing parts of northern Michigan and Wisconsin. One of the pipeline supports was damaged this summer, apparently by a boat cable. Placing the pipes beneath a busy shipping lane with no protective cover violated the state's duty to protect the public's interest in Great Lakes waters and bottomlands, the document said.

TRAVERSE CITY, Mich. A Michigan regulatory panel on Tuesday refused to grant quick permission to run a new oil pipeline beneath a channel that connects two of the Great Lakes, deciding instead to conduct a full review. Enbridge filed an application in April with the Michigan Public Service Commission to relocate a segment of its Line 5 that extends beneath the Straits of Mackinac, which links Lakes Huron and Michigan. Enbridge asked the state commission to approve the plan immediately, arguing that the agency in effect had already given permission by allowing the original Line 5 in 1953. Enbridge has already shown that they cannot be trusted, said Sean McBrearty of the environmental coalition Oil & Water Don't Mix. Circuit Judge James Jamo was scheduled to hear arguments Tuesday on whether to extend the order or allow oil to resume flowing through the pipes.

LANSING, Mich. The Ingham County Circuit Court ordered Thursday that Enbridge Energy must cease all operations of the Line 5 oil pipeline located in the Straits of Mackinac. The courts ruling comes after Michigan Attorney General Dana Nessel filed a motion for a temporary restraining requiring Enbridge to cease operations on Monday. The east leg has ceased operations since last week after damage was discovered on Line 5. Work must continue toward complete removal of Line 5 from our waters.The Alberta, Canada-based company discovered damage to the pipelines anchor support on June 18. According to Whitmer, the damaged anchor support lies approximately 150 feet (46 meters) from a section of the pipeline where damage to the pipeline coating was discovered on or around May 26.

Michigan Governor Gretchen Whitmer demanded Friday that Enbridge Energy provide proof that the damage to one of its dual oil pipelines under the Straits of Mackinac will not pose a threat to the area. Whitmer said the damage and how it occurred calls into question the viability of the pipeline. Thats why I am requesting Enbridge turn over to the State of Michigan all relevant information about this most recent damage and provide affirmative evidence that establishes the integrity of the pipeline, Whitmer said in a statement. Duffy clarified that the problem does not affect the pipeline, which he said was shut down as a precaution. The EPA determined that Enbridge neglected to properly evaluate thousands of shallow dents on its Lakehead Pipeline System, which runs across northern Minnesota and northwestern Wisconsin.
