Given the changes in the oil markets and Congress’ plan for a border adjustment tax, this could well be a pipeline to nowhere. Extracting oil from Alberta oil sands is much more costly than fracking in the Permian Basin. When you add in the 20% tax refiners would have to pay for Canadian oil, imports are likely a non-starter.
The pipeline will also carry crude from the North Dakota fields. Most of this is now shipped by tank car.
