Enbridge calls Line 5 incident ‘dangerous’ but files no official safety report

Despite describing an incursion on its Line 5 oil pipeline last month as “dangerous” and “criminal,” the pipeline operator Enbridge Energy did not file a report to the federal agency that tracks pipeline safety problems.

Protesters gathered at an exposed section of the pipeline on October 19, and one of them took a wrench to a manual shutoff valve. Enbridge spokesperson Ryan Duffy said the company’s control center shut down the flow of oil before the protester actually started cranking on the valve.

Now, the FBI is investigating, but federal pipeline safety regulators remain in the dark about exactly what happened.

That’s because federal regulations only require certain safety problems to be reported if they last more than five days. Duffy said the problems caused by the demonstrators “did not meet the criteria for a report.”

Bill Caram, executive director of the Pipeline Safety Trust, called the five-day rule “a loophole that drives us crazy.” He said the trust has been urging legislators and regulators for close to a decade to require reporting of all safety problems regardless of how long they last.

Caram said emergency valve shutoffs can overpressurize and weaken pipelines. He said the October incident on Line 5 is an example of a situation that should trigger a report but was exempt from current reporting rules.

“The unplanned closure of a valve is a condition that could lead to an imminent hazard. We believe regulators should know when these kinds of potential imminent hazards have happened on a pipeline,” Caram said.

“It doesn’t matter that it was fixed within five days or not. Just the fact that it happened makes it worth reporting.”

Small problems that go unreported can swell into bigger problems, said Caram -- like last month’s oil spill off the coast of California.

Duffy said Line 5 remains safe, and Enbridge “did keep PHMSA [the federal Pipeline and Hazardous Materials Safety Administration] updated on what happened” during the pipeline incursion. He did not answer followup questions about what the company told the administration in those updates.

This story's original headline stated that the Oct. 19 incursion on Enbridge's Line 5 was "not reported to federal safety regulators." An Enbridge spokesperson said the company was in touch with its federal regulatory agency by phone, and the headline has since been updated.
