TRAVERSE CITY, Michigan (AP) — Michigan Gov. Gretchen Whitmer took legal action Friday to shut down a pipeline that carries oil beneath a channel linking two of the Great Lakes.
Whitmer’s office notified Canadian company Enbridge Inc. that it was revoking an easement granted 67 years ago to extend a roughly 4-mile (6.4-kilometer) section of the pipeline through the Straits of Mackinac. The revocation takes effect in 180 days, when the flow of oil must stop.
“Enbridge has routinely refused to take action to protect our Great Lakes and the millions of Americans who depend on them for clean drinking water and good jobs,” the Democratic governor said in a statement. “They have repeatedly violated the terms of the 1953 easement by ignoring structural problems that put our Great Lakes and our families at risk.
“Most importantly, Enbridge has imposed on the people of Michigan an unacceptable risk of a catastrophic oil spill in the Great Lakes that could devastate our economy and way of life.”
Michigan Attorney General Dana Nessel filed a lawsuit Friday to carry out Whitmer’s decision. Another pending case that Nessel filed last year targets the pipeline as a public nuisance.
Enbridge said there was “no credible basis” for Whitmer’s action.
“Line 5 remains safe, as envisioned by the 1953 Easement, and as recently validated by our federal safety regulator,” said Vern Yu, the company’s president for liquids pipelines.
Line 5 is part of Enbridge’s Lakehead network, which carries oil from western Canada to refineries in the U.S. and Ontario. The pipeline moves about 23 million gallons (87 million liters) daily between Superior, Wisconsin, and Sarnia, Ontario, traversing parts of northern Michigan and Wisconsin.
The underwater section beneath the Straits of Mackinac, which connects Lake Huron and Lake Michigan, is divided into two pipes that are 20 inches (50 centimeters) in diameter. Enbridge says they are in good condition and have never leaked.
Environmentalists say they’re vulnerable and that closing Line 5 should be part of a global effort to curb use of climate-warming fossil fuels.
“Line 5 remains exposed to uncontrollable and powerful forces, including exceptionally strong currents, lakebed scouring, new anchor and cable strikes and corrosion,” said Liz Kirkwood of For Love of Water.
Enbridge reached an agreement with then-Gov. Rick Snyder, a Republican, in 2018 to replace the underwater portion with a new pipe that would be housed in a tunnel to be drilled through bedrock beneath the straits.
The company is seeking state and federal permits for the $500 million project, which is not affected by Whitmer’s shutdown order.
Environmental activists, native tribes and some elected officials began pushing to decommission Line 5 after another Enbridge pipe spilled at least 843,000 gallons (3.2 million liters) of oil in the Kalamazoo River in southern Michigan in 2010.
Pressure grew as the company reported gaps in protective coating and installed supports when erosion opened wide spaces between sections of pipe and the lake bed.
An anchor dragged by a commercial tug and barge dented both pipes in April 2018. One of the pipeline supports was damaged this summer, apparently by a boat cable.
In a termination notice, Whitmer’s office said the easement should not have been granted in 1953. 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.
It referred to a Michigan Technological University report that said oil discharged in the straits could harm fish and foul hundreds of miles of beaches, dunes and wetlands.
The notice said Enbridge repeatedly violated a requirement that the pipelines rest on the lake bed or have other supports at least every 75 feet (22 meters). Spaces exceeding the threshold have been detected as far back as 1963 and most were never dealt with, it said.
Enbridge has repeatedly defended its operation of the pipeline, saying the coating gaps posed no serious threat. It has installed more than 120 supports to improve stability and stepped up patrols and other measures to prevent anchor strikes.
The company said shutting down Line 5 would cause shortages of crude oil for refineries in Michigan, Ohio, Pennsylvania and eastern Canada, as well as propane shortages in northern Michigan. It also would boost shipments of oil by rail or trucks, Enbridge said.
“Today’s move would kill jobs and increase fuel costs,” said Geno Alessandrini of the Michigan Laborers Union, which joined industry groups in criticizing Whitmer’s decision. “That’s the last thing Michigan needs as we work to overcome the coronavirus pandemic.”
Republican state Sen. Jim Stamas said the governor had sided with “environmental extremists” instead of “hardworking Northern Michigan families.”
Democratic U.S. Sen. Gary Peters, a member of the Senate committee that oversees the U.S. Pipeline and Hazardous Materials Safety Administration, endorsed Whitmer’s move and said he would work with officials “to swiftly evaluate alternatives to Line 5 while continuing to hold Enbridge accountable.”
