Washington, DCâ(ENEWSPF)âAugust 22, 2014. This week, the State Department released documents revealing a scheme by Canadian tar sands giant Enbridge to bypass the Presidential Permit process for expansion of its Alberta Clipper tar sands pipeline. Enbridge has applied to double the capacity of the pipeline, also known as Line 67, to put it on par with the tar sands carrying capacity of the controversial Keystone XL pipeline. The State Department has previously made clear that any such expansion requires approval and comprehensive environmental review, and is currently undertaking that review.
