    Bottles of mustard gas were among the hazardous materials held at the Pueblo Chemical Weapons Depot from 1942 to 1996, when the facility served as a weapons storage site. Today, mustard gas shells, along with other dangerous projectiles stored at the site, are currently being destroyed  at the Pueblo Chemical Agent Destruction Pilot Plant.
