The Koch Nitrogen plan has been threatened, at least that's the impression the deputies are under.
"We do have a threat, once the threat has been confirmed then we're going to roll our units through the area," says Major Mike Moore.
It's a drill, Moore says training exercises are taken as seriously as the real thing.
"The deputies, every day when they leave home, know that anything can happen, so this is just part of their job," he says.
Camera are set up to keep an eye on the perimeter, swat teams suit up, and finally a suspect is taken down.
Just this week several universities including LSU faced bomb threats similar to the hypothetical situation OPSO is responding to in Sterlington. Moore says when law enforcement is ready, the situation will end in an arrest, like that of William Bouvay, the man facing charges connected to the LSU bomb threat.
"We have equipment that we need to test and also we need to know what our response time is in the event we were to have an actual threat," says Moore.
And after a rewarding run-through, Ouachita Parish deputies say they're ready for whatever comes their way.
"We always want to prepare for the worst and hope for the best," says Moore.
