==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."
