Mission and Safety

The Pueblo Chemical Agent-Destruction Pilot Plant, or PCAPP, is safely and efficiently destroying the stockpile of chemical weapons currently in storage at the U.S. Army Pueblo Chemical Depot, or PCD, since the 1950s. The Department of Defense’s Program Executive Office, Assembled Chemical Weapons Alternatives, known as PEO ACWA, is responsible for safely destroying the depot’s mustard agent-filled projectiles, thereby eliminating the risk associated with continued storage. The safety of the workforce, neighboring communities, and the environment remains the program’s top priority.
