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.
