U.S. Chemical Weapons Stockpile Destroyed
The Program Executive Office, Assembled Chemical Weapons Alternatives, known as PEO ACWA, oversaw the safe and environmentally compliant destruction of the remaining 10% of the declared U.S. chemical weapons stockpile, stored at the U.S. Army Pueblo Chemical Depot in Colorado, completed in June 2023, and the Blue Grass Army Depot in Kentucky, completed in July 2023 in compliance with the Chemical Weapons Convention, or CWC, treaty commitment date of 30 September 2023. Destruction was conducted at the Pueblo Chemical Agent-Destruction Pilot Plant, or PCAPP, in Colorado and the Blue Grass Chemical Agent-Destruction Pilot Plant, or BGCAPP, in Kentucky. The U.S. Army Chemical Materials Agency (now Activity) destroyed the other 90% of the nation's stockpile.
PEO ACWA, headquartered at Aberdeen Proving Ground in Maryland, is responsible for the safe and environmentally compliant closure of the Colorado and Kentucky destruction facilities, scheduled to finish in 2028. The U.S. Army has confirmed the absence of chemical agent liability at both sites. When the closure phase is complete, the PEO ACWA program will end, and the organization will no longer exist. All program offices are now at minimal staffing as closure is well underway.
