Projectiles at Blue Grass

REQUIREMENT BG-2 DESTRUCTION OF APPROXIMATELY 15,000 MUSTARD AGENT H-FILLED 155-mm PROJECTILES AT BLUE GRASS... 

Requirement BG-2 is for the destruction of all 155-mm mustard agent H projectiles at Blue Grass. 

If used to destroy mustard agent-filled 155-mm projectiles at Blue Grass, the explosive loading would be well within the capability of the DAVINCH units— that is, even if a 20- to 30-kg donor charge is used, the combined explosive weight of the projectile burster (0.186 kg) and the donor charge would still be less than the explosive containment capabilities ofthcDV65. 

The same factors involved in evaluating the public and regulatory acceptability of the DAVINCH for processing 155-mm mustard agent-filled projectiles at Blue Grass should also apply to Pueblo. 

Not all the projectiles in storage at Blue Grass Army Depot contain explosive burster charges. Those projectiles with bursters (155-mm HD rounds) are pro-... 

At Blue Grass the 70,000 noncontaminated rocket motors and 15,000 mustard agent-filled projectiles are expected to be consistent feedstocks. For these applications, the flexibility of an EDT is not an issue unless the Army chooses to use one EDT for both applications. 

In accordance with the Chemical Weapons Convention, the United States is destroying (via chemical neutralization followed by biotreatment or supercritical water oxidation) the remaining sulfur mustard stored at the Blue Grass and Pueblo Army Depots (PEO ACWA, 2014). The sulfur mustard occurs in artillery projectiles and mortar rounds. Destruction is scheduled for completion by 2019 at Pueblo Army Depot and 2023 at Blue Grass Army Depot.
