The Blue Grass Chemical Agent-Destruction Pilot Plant (BGCAPP) is safely destroying a chemical weapons stockpile stored at the Blue Grass Army Depot, or BGAD. The depot, located near Richmond, Kentucky, provides conventional ammunition services, chemical defense equipment management and manufacturing capabilities for the Department of Defense. The Blue Grass Chemical Activity, a tenant of the 15,000-acre depot, is responsible for safekeeping the chemical weapons stockpile stored at the depot. Together, the U.S. Army and the community surrounding BGAD are working in a committed partnership to support the safe destruction of the stockpile.
The Blue Grass chemical weapons stockpile was originally comprised of 523 U.S. tons of weaponized blister and nerve agent in M55 rockets, 155mm projectiles and 8-inch projectiles. Destruction operations began in June 2019 and are scheduled to complete by the congressionally mandated deadline of Dec. 31, 2023.
