Try checking out Google for articles on the 1/2 billion dollar Kalamazoo River clean up caused by a tar sands pipeline break.

[no-to-illegals]

speaking in terms of tar sands, and imho tar sands (raw tar sands), should not be transported via a pipeline. There are refinement methods to eliminate some of the erosion which occurs during pipeline transfers, and not having researched this particular (pipeline break) am typing without full knowledge regarding this incident. Other transfer methods are available if a product is deemed too erosive for pipeline transfer. Train, and truck. I appreciate your coming back with additional information I did not have.
