O'Brien's has had its hands in the botched clean-up efforts of almost every high-profile oil spill disaster in recent U.S. history, including the Exxon Valdez spill, the BP Deepwater Horizon spill, the Enbridge tar sands pipeline spill into the Kalamazoo River, and Hurricane Sandy.

What we already know from existing analysis is that the Keystone XL tar sands pipeline is not in our national interest. The pipeline means worsening climate change. Piping it through the U.S. heartland would put our ranchers and farmers at risk from difficult to clean up oil spills.

In a presentation to investors this week, the company provided three quotes from anonymous local residents, fisherman and river enthusiasts, who gush about what Enbridge's tar sands spill has done for the community. Who are these people and where do they come from?

The National Transportation Safety Board (NTSB) heard the major findings of its two-year investigation of the Enbridge tar sands pipeline spill, which released more than a million gallons of corrosive tar sands into the Kalamazoo River watershed in July 2010.

On the night of July 25, 2010, a section of the continent's vast pipeline network spilled around a million gallons of chemical-laden crude into western Michigan waterways. In the debate over our nation's energy future, the Kalamazoo River spill may prove even more important than the BP blowout.
