complex began agent-destruction operations, destroying 4.2-inch mortar rounds. SDC operations marked the beginning of the third and final chemical weapons destruction campaign at PCAPP. On April 19, 2022, BGCAPP destroyed the last M55 rocket containing VX nerve agent, thus completing the fourth and penultimate destruction campaign. On July 6, 2022, the fifth and final destruction campaign at BGCAPP began when the first M55 rocket containing GB nerve agent was destroyed. On July 20, 2022, the second munitions campaign at PCAPP was completed with more than 383,000 105mm projectiles destroyed. As of Sept. 9, 2022, 50% of the original stockpile of chemical agent at BGCAPP has been destroyed. Chemical weapons destruction in Colorado PEO ACWA is responsible for the management of PCAPP at the U.S. Army Pueblo Chemical Depot, located near Pueblo, Colorado. The Pueblo Chemical Depot was originally constructed as the Pueblo Ordnance Depot in 1942 and has been responsible for safe and secure storage of 2,613 U.S. tons of mustard agent in projectiles and mortars, though PCAPP operations are reducing the amount of agent stored at PCD. The weapons have been stored at the depot since the 1950s. The destruction technology used is neutralization followed by biotreatment. The follow-on process, biological treatment, consists of breaking down the product of neutralization called hydrolysate by microbial digestion. Additionally, three SDCs are augmenting PCAPP's neutralization/biotreatment technology to destroy 4.2-inch mortar rounds and any projectiles which have been found unsuitable for processing through the main plant. Chemical weapons destruction in Kentucky PEO ACWA is responsible for the management of BGCAPP at the Blue Grass Army Depot located in east central Kentucky. The installation stores and maintains conventional munitions and provides chemical defense equipment and special operations support to the Department of Defense. The Blue Grass Chemical Activity, a tenant of the depot, is responsible for the safeguarding of a portion of the U.S. chemical weapons stockpile, 523 tons of nerve agents GB and VX and mustard agent in rockets and projectiles. BGCAPP is also using neutralization to destroy chemical agent while Static Detonation Chamber technology was used to process mustard agent-filled projectiles, and will be used to destroy containerized, drained rocket warheads and overpacked munitions. PEO ACWA schedule Destruction of the remaining U.S. chemical weapons stockpile should be completed by the Chemical Weapons Convention treaty commitment of Sept. 30, 2023. U.S. Public Law mandates stockpile destruction Dec. 31, 2023. Public Involvement The Blue
