Here's what it looked like before the fire. And a link to the Google Map of the location. Selene drives down Choteau Trafficway to Front Street (about two blocks to the East of the plant site) five nights a week on her way to her blackjack training class at one of the riverboat casinos further to the East. I just drove by it myself a week ago, within sight of the plant.
The immediate concern now is the railcars sitting on the siding (pretty much in the same location as those in the picture here). They contain more of the same stuff that has been burning, and one of the cars is venting rather fiercely right now. Also, the EPA just brought an air sampling aircraft up from Dallas and flew through the smoke plume to see what, exactly, we're dealing with. Downtown Airport was warning aircraft that flew through the smoke to wash the airframe as soon as possible after landing since the stuff that is burning is essentially paint thinner.
The smoke column itself, which I couldn't see from my office, was amazingly large and impressive on the way home. I wish I'd had a camera. It looked like a giant black tornado was about to eat Downtown.
