I beg to differ with this point. If you're an educated person not looking to work in a blue collar job your economic prospects in areas like this are limited. The technically inclined and the otherwise ambitious move away to seek better opportunities elsewhere. I lived in a small industrial city for a while many years ago and saw this phenomena for myself. Those who were able left in their teens to major economic centers for tertiary education and considered going back home worse than a death sentence. What was left in the wake of this phenomena was a creeping ghetto, an economic wasteland that only begat more poverty.
I think a part of the problem is that, for someone in a little town like the one in the article, regulatory authorities and the federal legislature are peopled largely with individuals who reside a thousand miles away.
That just can't happen in basically any European country.
If the state doesn't lack the teeth to fix this, why would they choose to compete for federal attention with an order of magnitude more people?
I'm not sure, Louisiana does have a Department of Environmental Quality [1]. In Illinois we had a similar issue play out this year. The Governor is the one who ended up banning the plant's use of ethylene oxide [2]. It looks an obscure state law allowed for that action:
"Invoking rarely used authority in state law, Illinois EPA Director John Kim prohibited Sterigenics from pumping ethylene oxide gas into massive chambers used to sterilize medical equipment, pharmaceutical drugs, spices and food."

From what I gathered this is rooted in the difference between the regulatory principles of the US and most other Western countries. In Europe you usually have to proof first that whatever you do will be reasonably safe, then you can do it. In the US you can do many things without someone checking first, but if it's later shown that you harmed someone you have to pay damages and/or people will be send to prison.
