Chemical Destruction Plant Eliminates 155mm Mustard Projectiles from Colorado Stockpile

The Pueblo Chemical Agent-Destruction Pilot Plant (PCAPP) team announced the safe and efficient destruction of nearly 300,000 155mm chemical weapons projectiles stored at the U.S. Army Pueblo Chemical Depot in Colorado, marking the end of the plant's first munitions campaign. In 1997, a presidential directive and the ratification of the Chemical Weapons Convention – an international treaty to destroy chemical weapons – called upon all member nations to destroy their chemical weapons and production facilities. Bechtel leads the team contracted to help the United States complete its obligations under this treaty by safely destroying 2,611 tons of mustard agent inside munitions.
