The Pueblo Chemical Agent-Destruction Pilot Plant is safely and efficiently destroying the stockpile of chemical weapons stored at the U.S. Army Pueblo Chemical Depot. The pilot plant is using neutralization followed by biotreatment as the technology to destroy munitions containing more than 2,600 tons of mustard agent. Additionally, construction continues for three Static Detonation Chambers that will augment the main plant by destroying problematic chemical munitions that cannot be easily processed using the main plant’s automated equipment.

In September 2002, the Bechtel Pueblo Team was awarded the systems contract to design, construct, systemize, pilot test, operate and close the plant. The Program Executive Office, Assembled Chemical Weapons Alternatives program, known as PEO ACWA, is the Department of Defense agency responsible for managing the destruction of the Pueblo chemical weapons stockpile and oversees the Bechtel Pueblo contract.
