Security personnel noticed something suspicious about a truck that tried to enter through the truck gate, according to a statement on the facility's Facebook page. They treated the situation as an "explosive threat." Local, state and federal agencies were notified and no one was allowed to enter the Aresnal property.

All 5,000 employees were sent home at 1:45 p.m.

Route 15, which passes  in front of the facility, remained closed in both directions.
