Among many other things
Your links pretty firmly establish that no one is trying to build new refineries, as I stated. I'm still skeptical that the reason that they don't even try is because it is so hard. It seems obvious to me that if the number of refineries is going down, that there is an incentive to drop them rather than to build new ones.
I am skeptical that a refiner can only operate at a 5% margin, when oil companies are earning record profits. Just can't get those two statements to make any sense together. If it is true then there is something very wrong with the markets and it has nothing to do with NIMBYism.
