The Blue Grass Chemical Agent-Destruction Pilot Plant is safely destroying the remaining U.S. chemical weapons stockpile stored at the Blue Grass Army Depot, Kentucky. The depot originally stored 523 U.S. tons of mustard and nerve agent contained in projectiles and rockets. BGCAPP is using neutralization and Static Detonation Chamber units to destroy the munitions. Agent destruction operations began June 7, 2019, and the program is targeting completion by the Chemical Weapons Convention treaty commitment of Sept. 30, 2023. U.S. Public Law mandates stockpile destruction by Dec. 31, 2023.
