Gov. Whitmer: Enbridge dodging responsibility for potential spill

Mike Koby, president of U.S. operations for Enbridge Energy LP, repeated the promise in a letter Monday to Dan Eichenger, director of the state department.

But Eichenger responded Wednesday that the company still hadn't gone far enough.

Line 5 carries oil and liquids used in propane from Superior, Wisconsin, to Sarnia, Ontario. A nearly 4-mile-long (6.4-kilometers-long) segment, laid in 1953 beneath the Straits of Mackinac, is divided into two pipes.

The straits connects Lake Huron and Lake Michigan. It is a popular tourist draw and has cultural and economic importance to native tribes that operate commercial fishing vessels in the area.

The state is asking Enbridge to carry $900 million of liability insurance and have about $1.88 billion in additional assets available for a worst-case rupture in the straits. Enbridge says it's doing so under the 2018 tunnel agreement with Snyder.

But that deal was signed by Enbridge subsidiaries -- not Enbridge Inc., their parent company based in Calgary, Alberta.

The disagreement centers on whether the parent company is bound by the deal -- or by terms of a 1953 easement the state granted to put the dual pipelines in the straits.

Based on a contractor's analysis, the state contends Enbridge Inc. is off the hook and should make an explicit commitment in writing.

But in his letter, Koby told Eichenger the 2018 agreement requires that “the Enbridge entity or entities that own and operate Line 5, or the parent companies ... will maintain in force financial assurance mechanisms" to deal with a spill.

He added that “the substantial assets of Enbridge subsidiaries in the United States are more than sufficient to cover Enbridge’s assurance obligations." Under the U.S. Oil Pollution Act, the owner of Line 5 “would be obligated as a responsible party to assume the cost of any cleanup,” Koby said.

Environmental groups that have long pushed to shut down the pipeline said the financial dispute should be the final straw.

“If the governor now fails to begin the legal process of decommissioning Line 5 she will be responsible for the financial consequences of any Line 5 rupture on her watch,” said Sean McBrearty, coordinator of Oil & Water Don't Mix.

A state judge ordered a temporary Line 5 shutdown last month after Enbridge reported damage to a steel anchor holding a section of one pipe in place. The judge later allowed oil to resume flowing through the other underwater pipe.
