The National Transportation Safety Board (NTSB) heard the major findings of its two year investigation of the Enbridge tar sands pipeline spill, which released over a million gallons of corrosive tar sands into the Kalamazoo River watershed in July 2010. The Kalamazoo spill has clearly demonstrated how dirty and dangerous tar sands pipelines are, even more dangerous than conventional oil pipelines.
Nearly two years after what has become the most expensive pipeline disaster in U.S. history, emergency responders are still struggling to clean up the Kalamazoo River. The government's investigation raises serious questions about whether corrosive tar sands can be safely moved on the U.S. pipeline system, especially when they cross farms and waters in the U.S. heartland as the proposed Keystone XL tar sands pipeline would do.
In particular, the NTSB provides a damning picture of Enbridgeâ€™s pipeline safety measures. As one NTSB board member put it, this investigation did not only show corrosion of Enbridgeâ€™s tar sands pipeline, but also demonstrates systemic corrosion of Enbridgeâ€™s pipeline safety program.
"Delegating too much authority to the regulated is tantamount to letting the fox guard the hen house." Deborah Hersman, Chair of NTSB
NTSBâ€™s report shows in glaring detail that the $807 million tar sands spill was the result of Enbridge taking advantage of weak pipeline safety regulations and poor oversight by federal pipeline safety regulators at the Pipeline and Hazardous Safety Materials Administration (PHMSA). Enbridge failed to identify multiple risks to pipeline safety, failed to properly identify the spill, and lacked the resources or planning to mitigate the spill. NTSB staff found that the Kalamazoo spill could and should have addressed the causes of the Kalamazoo spill proactively.
