Pueblo Chemical Depot Information

The U.S. Army Pueblo Chemical Depot (PCD), which reports to the U.S. Army Chemical Materials Activity (CMA), is responsible for the safe and secure storage of the chemical weapons stockpile in Colorado. PCD is commanded by COL Rodney D. McCutcheon. Located near Pueblo, Colorado, PCD is one of several Army installations in the United States that previously stored chemical weapons. Encompassing approximately 23,000 acres, the depot’s mission has shifted and expanded since PCD was created in 1942. After completing our mission of the safe, secure storage of the chemical weapons stockpile in June 2023, the depot is undergoing closure operations which will take place over the next several years. The chemical stockpile was comprised of 2,600 tons of mustard agent in approximately 780,000 munitions. The Program Executive Office, Assembled Chemical Weapons Alternatives, (PEO-ACWA), is the Department of Defense program responsible for the destruction of chemical weapons in Colorado. Working in partnership with the community, the Army selected neutralization followed by biotreatment to destroy the chemical weapons stockpile at PCD. Bechtel Pueblo is the systems contractor that designed and constructed the Pueblo Chemical Agent-Destruction Pilot Plant (PCAPP) and will close PCAPP.
