Second of three chemical weapons destruction campaigns completed in Pueblo
PUEBLO, Colo. – The Pueblo Chemical Agent Destruction Pilot Plant (PCAPP) team has completed the destruction of more than 383,000 mustard-filled 105mm projectiles.
The 105mm projectiles are the second of three ordnance destruction campaigns to be destroyed in the
Pueblo Chemical Depot (PCD).
PCD originally stocked three different types of mustard filled weapons: two projectile types, 155mm
and 105mm 4.2 inch mortar shells.
The final destruction campaign of the 4.2-inch mortar shells is currently underway.
The 105 mm projectiles were destroyed under the supervision of trained operators using
robotic technology for dismantling and emptying ammunition. The mustard agent has been neutralized and the
the resulting product, known as the hydrolyzate, was broken down into salt, water and organic matter using
microbes in a bioprocessing process.
Approximately 54 of the 105mm projectiles were deemed unsuitable for automated processing and will be
later be destroyed using the Static Detonation Chamber complex.
Chemical weapons destruction operations began in March 2015 when more than 780,000 munitions
included the original chemical weapons stockpile stored at the PCD.
As of July 20, approximately 94,000 munitions remained. The destruction of 2,334.6 US tons or 89% of the mustard agents was reported to the Organization for the Prohibition of Chemical Weapons (OPCW), an intergovernmental organization that implements the Chemical Weapons Convention treaty.
