Enbridge rejects Michigan’s order to shut down Line 5 pipeline through Great Lakes

The company is seeking state and federal permits for the $500 million project, which is not affected by the shutdown order.

Michigan’s demand that Enbridge Inc. shut down an oil pipeline that runs through a channel linking two of the Great Lakes is based on bad information and political posturing and will be ignored, the Calgary-based company said on Jan. 12.

Democratic Gov. Gretchen Whitmer in November moved to revoke a 1953 state easement that allowed part of the Canadian company’s Line 5 to be placed along the bottom of the Straits of Mackinac, charging that Enbridge had repeatedly violated the terms and put the lakes at risk.

Whitmer gave the company 180 days — until May 12 — to turn off the flow. Enbridge filed a federal lawsuit challenging the order shortly after it was issued.

In a point-by-point-response to the state’s termination notice, Vern Yu, president for liquids pipelines, said in a letter on Jan. 12 that Enbridge won’t close Line 5.


“Our dual pipelines in the straits are safe, fit for service and in full compliance with the federal safety standards that govern them,” Yu said.

Line 5 is part of Enbridge’s Lakehead network, which carries oil and liquids used in propane from Western Canada to refineries in the U.S. and Ontario. The pipeline moves about 87 million litres daily between Superior, Wisc., and Sarnia, Ont., 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 Enbridge says are in good shape and have never leaked.

Whitmer, however, agrees with environmentalists, Native American tribes and other critics who contend they’re vulnerable to a catastrophic spill.

Enbridge reached an agreement with then-Michigan 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 beneath the straits.

The company is seeking state and federal permits for the $500 million project, which is not affected by the shutdown order.

Whitmer’s order said granting the easement in a busy shipping lane vulnerable to anchor strikes was a mistake and Enbridge had made things worse, repeatedly violating a requirement that the pipelines rest on the lake bed or have other supports at least every 22 metres.
