You can thank the environmentalist crowd for that. We can't have any of that harmful refinery business going on in this here pristine country of ours, no sir.
When I was young there was a Shell refinery less than 5 miles from my house, one of our neighbors was an engineer there and he took me on a tour one day, I was probably no more than 10 years old but remember being amazed at the myriad of pipes seemingly going in every conceivable direction. Place was decommissioned a few years later and is now only a storage and shipping facility. I used to go there regularly when I was running fuel tankers.
