N.W.T. Oil Pipeline Leak Estimate Grows

Enbridge crews clean up the oil spill at the Norman Wells pipeline near Wrigley, N.W.T. The company said Monday that 700 to 1,500 barrels of oil leaked from the pipeline on May 9. (Submitted by D'Arcy J. Moses)Enbridge says up to 1,500 barrels of oil may have leaked from its pipeline in the Northwest Territories last month, much higher than the company’s initial estimate of four barrels.

Company spokesperson Gina Jordan said late Monday that the volume of oil that spilled from its Norman Wells pipeline “could range from a minimum of 700 barrels to a maximum of 1,500 barrels.”

“Based on its current analysis, Enbridge anticipates the probability that the maximum volume would be exceeded to be low,” Jordan wrote in an email.

Enbridge had originally reported that just four barrels of oil leaked on May 9 from the pipeline, located about 50 kilometres south of the community of Wrigley, N.W.T.

But on Friday, Jordan said Enbridge cleanup crews had removed about 90 barrels of oil from the spill site. That figure was updated to 100 barrels on Monday.

‘Subsurface impacts’ not included

The news did not surprise Wrigley Chief Tim Lennie, who was among the first people to discover the leak.

“We definitely said there wasn’t four barrels, it was a lot more, so scientifically they’ve just actually proven us right,” Lennie told CBC News.

Jordan said third-party experts are trying to more accurately determine subsurface contamination, and once that is complete a revised estimate of the size of the release can be determined.

“Our original four barrel estimate was based on oil collected at the surface and did not take into account the subsurface impacts, which were believed to be not significantly different,” Jordan wrote in the email.

“The increase in subsurface oil was discovered during the ongoing environmental site assessment, which includes subsurface analysis and is standard practice for all releases.”

River not affected, says company

Jordan maintained that the oil leak has had no impact on the nearby Willowlake River.

But Lennie said he has heard otherwise from people living in the area.

“[The company] said there has been no impact at all on anything, you know, to date. I mean, it’s just been ridiculous,” he said.

Lennie said he has scheduled a public meeting on Wednesday to update Wrigley residents on the situation.

The Norman Wells pipeline was back up and running on May 20, after repairs were made. Enbridge says the cause of the pipeline leak remains under investigation.
