Think about it, BP is shut down, CONOCO is shut down and TESORO is running exclusively on shale oil. That leaves one Anacortes refinery and US Oil in WA.
Cherry Point is 225,000 BPD
COP Ferndale is 100,000 BPD
The West Coast imports 1,100,000 BPD.
There is not a lack of West Coast refining capacity, to pick up this oil. There is too much foreign imported oil displacing it.
