Enbridge, the Canadian company poised to build the controversial Northern Gateway Pipeline, received a scathing assessment this week from the U.S. National Transportation Safety Board (NTSB) after an inquiry into a 2010 pipeline rupture in Michigan revealed the company’s mismanagement of what unfolded into a “tragic and needless” disaster.
A combination of “human error” and miscommunication culminated in the reckless release of over 843,000 gallons of Albertan diluted bitumen
from the Enbridge Line 6B into the Kalamazoo River. The investigation found that 81 percent of the tar sands oil spill was the result of the company’s baffling response to rupture alerts, which prompted monitors to pump additional oil into the line – twice – rather than close the line’s remote controlled valves. The rupture went undetected for over 17 hours, leading to the most expensive onshore clean up effort in American history
, with a price tag approaching $800 million.
In her opening remarks, NTSB
’s chair Deborah Hersman likened Enbridge to the incompetent Keystone Kops
of silent film, suggesting their bewildering response amounted to nothing more than a pantomime. “Why didn’t they recognize what was happening,” Hersman asked
. “What took so long?”
According to the Board’s investigation, Enbridge knew about the ailing condition of Line 6B for at least five years before the rupture. A 2005 report identified about 15,000 defects with the aging pipeline that extends for 471-kilometers from Ontario to Indiana. Although nearly 900 of those defects had since been addressed, the NTSB found the 2010 rupture was caused by external corrosion at a site overlooked during the course of repairs.
Greenpeace Canada Climate and Energy Campaigner Mike Hudema suggests the significance of the NTSB’s findings should bear down on the current pipeline proposals under review in Canada.
“Today’s damning findings from the NTSB
reveal that Enbridge exploited weak regulation. They knew about the broken pipeline’s corrosion for five years and did nothing about it. Canadian officials must wake up and say no to Enbridge’s tar sands pipelines. This should be the last warning signal we need that Enbridge cannot be trusted to build a tar sands pipeline through the largest intact temperate rainforest left on the planet
. This tar sands pipeline should never be built.”
In response to the NTSB
findings Enbridge said
it has “already implemented, in 2010 and 2011, appropriate operational and procedural changes based on our own internal investigation,” adding, “as a result of our detailed investigation into the accident, and as part of our ongoing continuous improvement efforts, we have taken steps to address lessons learned and make incremental improvements aimed at preventing a similar accident from happening again in the future.”
In addition to finding “pervasive organizational failures at Enbridge,” the NTSB
panel also found fault with industry regulators. Hesman cautioned
that the “accident was the result of multiple mistakes and missteps by Enbridge but there is also regulatory culpability.” She added
, “delegating too much authority to the regulated [companies] to assess their own system risks and correct them is tantamount to the fox guarding the hen house.”
“Regulators need regulations and practices with teeth – and the resources to enable them to take corrective action before a spill, not after.”
And given Enbridge’s aggressive lobbying over the months leading up to the passing of bill C-38
“regulatory streamlining…for pipeline construction,” “improved efficiencies to the environmental assessment processes” as well as amendments to “the proposed ban on oil tanker traffic” and “greenhouse gas regulations in respect of quotas that affect the energy and pipeline industries” – the current political climate appears to be in favor of letting industry run amok at a time when what we need to be is cautious.
In the words of NTSB chair Hesman, the board’s findings should “force us to ask hard questions of this vital industry.”
