The Pueblo Chemical Depot was a chemical weapons storage site located in Pueblo County, Colorado, United States. The Pueblo Chemical Depot was one of the last two sites in the United States with chemical munitions and chemical materiel. The Pueblo Chemical Agent Destruction Pilot Plant (PCAPP) which is under the Program Executive Office, Assembled Chemical Weapons Alternatives (PEO ACWA) program destroyed its stockpile of 155mm and 105mm artillery shells and 4.2-inch mortars, all of which contained a form of the chemical agent mustard gas.
