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?

What does that mean for tar sands pipelines like Keystone XL and Northern Gateway?

The fact that tar sands pipelines are not in our national interest becomes clearer by the day.

The very nature of tar sands -- heavy and abrasive -- points to why tar sands pipelines have an abysmal safety record. But a drastically increased likelihood of spills is only where the problems begin.

On July 25, 2010, an oil company spilled more than a million gallons of toxic tar sands crude just a few miles from Susan Connolly's house. As the spill spread, they could smell the fumes. But it wasn't until later that night that they realized something was seriously wrong

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.

The federal investigation of the Kalamazoo tar sands spills clearly shows that the most expensive pipeline accident in U.S. history could have and should have been prevented.
