The U.S. is fully committed to achieving 100% destruction of its chemical weapons stockpile as soon as practicable, while protecting the workforce, public and environment.

The Program Executive Office, Assembled Chemical Weapons Alternatives, or PEO ACWA, is responsible for the destruction of the remaining U.S. chemical weapons stockpile stored at the U.S. Army Pueblo Chemical Depot in Colorado and the Blue Grass Army Depot in Kentucky.

In 2012, the U.S. Army Chemical Materials Agency, now known as the U.S. Army Chemical Materials Activity, completed destruction of nearly 90% of the original U.S. chemical weapons stockpile. PEO ACWA is destroying the remaining 10% of the stockpile, in accordance with the Chemical Weapons Convention.

In Colorado, the Pueblo Chemical Agent-Destruction Pilot Plant, or PCAPP, is destroying the stockpile using neutralization followed by biotreatment. In Kentucky, the Blue Grass Chemical Agent-Destruction Pilot Plant, or BGCAPP, is destroying the stockpile using neutralization. Both pilot plants, which are actively destroying munitions, are being augmented by Static Detonation Chamber units to eliminate difficult-to-process rounds and additionally, at Blue Grass, secondary waste from the destruction process. Destruction operations at both sites are scheduled to conclude by the Chemical Weapons Convention treaty commitment of Sept. 30, 2023. U.S. Public Law mandates stockpile destruction by Dec. 31, 2023.
