Maybe in the one port region, but has California stopped importing oil?
I cannot speak for California. I know that they are having a problem figuring out what to do with all the oil on the West Coast. I would guess that some of it is now being exported. Clinton made that legal.
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.
