Report: Enbridge stopped and restarted pipeline during oil spill

A report released last week by the National Transportation Safety Board shows employees in an Enbridge control center located in Edmonton, Alberta did not know they were pressurizing a ruptured oil pipeline in Michigan.

Employees in the control center felt they were dealing with false alarms due to pressure losses in the pipeline after a planned shutdown.

The pressure losses were not due to "column separation" as some thought (air and vapor pockets between slugs of oil in the pipeline). They were caused by a break in the line.

The rupture led to the spill, and the continued pumping made it worse. More than 840,000 gallons of oil spilled, according to Enbridge.

However, the EPA estimates that more than 1 million gallons of thick, tar sands oil have been removed from Talmadge Creek and the Kalamazoo River so far. The spill is still being cleaned up nearly two years later.

The NTSB estimates the pipeline ruptured around 5:58 p.m. on Sunday, July 25, 2010. Enbridge officials didn't know they had a spill on their hands for nearly 17 hours after the initial break.

In fact, employees increased the pressure in the pipeline - twice.

Oil spill clean up work along the Kalamazoo River, near Battle Creek, July, 2010

Tests suggest household wells near the 2010 Kalamazoo River oil spill have not been contaminated.

A pipeline break in July, 2010, resulted in more than 800 thousand gallons of crude oil leaking into the Kalamazoo River.   The cleanup of the river and the surrounding area continues.

Health officials have spent the past few years testing 150 wells in the spill zone.

 The EPA this week gave approval to Enbridge Energy’s plans for continuing its cleanup of an oil spill in the Kalamazoo River.    The plan suggests major cleanup operations may change next year.  

More than 840 thousand gallons of crude oil spewed from a broken pipeline near Marshall in July, 2010.   The exact amount remains in dispute.     

Hundreds of workers have spent the past 17 months removing the oil from the river.

Enbridge Energy says it’s done cleaning up oil that sank to the bottom of the Kalamazoo River until next spring.

“That doesn’t mean cleanup is done for the year it’s just going from one phase into another,” company spokemans Jason Manshum said.

Is there something missing in the latest plan to cleanup the Kalamazoo River oil spill?

The Kalamazoo River has been the site of a massive cleanup operation ever since a ruptured pipeline spewed more than 840 thousand gallons of Canadian oil sands crude near Marshall in July of 2010.

A Michigan State University professor says he’s concerned a revised plan for cleaning up an oil spill in the Kalamazoo River is missing details in one important area.

New Kalamazoo River oil spill cleanup plan due today

Cleanup crews work to remove oil from the Kalamazoo River near Battle Creek in August of 2010.

Nearly 15 months after an oil spill fouled miles of the Kalamazoo River, the pipeline’s owner is submitting an updated cleanup plan to the federal Environmental Protection Agency today.  

The July 2010 pipeline break spewed more than 840 thousand gallons of Canadian tar sands crude oil into the Kalamazoo River.   Hundreds of workers have spent the past year removing contaminated soil, sucking up submerged oil and rehabbing endangered wildlife. But the work is far from over.  

A company spokesman says senior Enbridge officials spent Thursday reviewing and revising the new cleanup plan, that the EPA demanded after the company missed an August deadline.  

The new plan will detail how Enbridge plans to complete the removal of submerged oil in the Kalamazoo River,  remove oil and contaminated soil beyond the river bank and how they’ll reassess their cleanup plans in 2012.  

Enbridge officials estimate the cleanup will eventually cost the pipeline company $700 million.

Estimated cost of cleaning up Kalamazoo River oil spill rising

Oil spill cleanup workers on the Kalamazoo River near Battle Creek in August, 2010.

The new estimate was part of paperwork Enbridge Energy filed today with the U.S. Securities and Exchange Commission.   The company says it’s revising its estimated cleanup costs, from $585 million to $700 million.  That's about a 20 percent increase.   

 “The cleanup cost to date includes some additional work around submerged oil….and those recovery operations….and just some more active remediation of the impacted environment." says Terri Larson,  an Enbridge spokeswoman,  "So there are a few factors that are at play within that expected increase.”

Dozens of people turned out for last night's EPA public meeting on the Kalamazoo River oil spill in Marshall

Dozens of people who turned out for a public hearing in Marshall on the cleanup of last Summer’ s oil spill in the Kalamazoo River left without hearing the news they wanted to hear….that the river will soon reopen.  

More than 766 thousand gallons of crude oil have been recovered during  the past twelve months.   But there are still large deposits of  submerged oil in three different parts of the river.
