Steve Horn commented on the blog post Keystone XL East? Enbridge’s Line 9 Tar Sands Pipeline
I think because tar sands crude is more corrosive and prone to spilling, as oppose to the sweet crude oil now coming from Africa and the Middle East and heading up to the Canadian market vis-a-vis the New England based pipeline infrastructure. I’m not a scientist though, so I could be wrong. That seems like the logic behind Friends of the Earth’s ecological grievances, though, if I had to guess.
