The U.S. Army Pueblo Chemical Depot originally stored more than 2,600 tons of the blister agent mustard in projectiles and mortar rounds.
Chemical Weapons Destruction Technologies
Technologies chosen to safely destroy the Pueblo stockpile.
Neutralization Followed by Biotreatment
The Assembled Chemical Weapons Alternatives program, the U.S. Army Pueblo Chemical Depot and the community worked together to select neutralization followed by biotreatment to destroy the chemical weapons stored at the depot.
Explosive Destruction System
The Explosive Destruction System, or EDS, augmented the pilot plant to destroy a number of problematic munitions that could not be easily destroyed by the main plant’s automated equipment. During two campaigns from March 2015 to December 2018, the EDS eliminated 951 items resulting in 3.82 tons of mustard agent destroyed.
Static Detonation Chamber
Three Static Detonation Chamber (SDC) units will augment the main plant by destroying all problematic munitions, including the 4.2-inch mortar rounds. PCAPP will employ three SDCs, each consisting of two units — the detonation chamber and the off-gas treatment system. The SDCs are expected to be operational by the end of 2020.
