Then you would need a "products pipeline" to get the output to market, rather than a "crude oil pipeline" to get it to a refinery.
The market for refined products in Northern Alberta is, shall we say, rather thin.
If there was a better economic answer than the Keystone XL pipeline, one can assume the principals would have proposed it.
There are, in fact, several hundred thousand miles of pipeline buried under U.S. soil already.
Yes: I know. There is a pipeline right up the road from me that takes refined products from the Wharf here in St. Marys County to Washington D.C. for Stuart Petroleum.
About 70 miles I would say. Never caused a problem.
Probably most people around here under 20 years old doesn’t even know it is there.
