OPSEC/ITAR Review Completed: 22 May 2017
Agenda
Introduction
• PCAPP basics
Pilot Test Objectives
Pilot Test Blocks and Results
2
PCAPP Facility is in Agent Operations
Designed to destroy 2,611 tons of mustard agent (HD) in mortar and projectiles stored at PCD
• Completed construction and systemization phases
Destruction operations began on 7 Sep 2016
• Destroyed more than 25,000 155mm HD projectiles
• Completed multiple pilot tests
Began feeding agent hydrolysate to biomass in April 2017

Pilot Test Objectives
Pilot testing provides the data to:
• Define critical operating parameters
• Demonstrate safe operations
• Validate environmental compliance
• Demonstrate efficient operations of the PCAPP
• Provide data for the Multiple Pathway Health Risk Assessment (MPHRA)
Pilot Testing uses a stepped-approached to characterizing plant impacts
• Testing is organized into “blocks” to incrementally assess system impacts

DEMONSTRATE THE PROCESS CRITERIA AND OPERATINGCONDITIONS THAT ENSURE THE PROTECTION OF HUMAN
HEALTH AND THE ENVIRONMENT
PCAPP Block Functions
Block 1 - Projectile Mortar Disassembly (PMDs) machines and associated and air monitoring systems
• Separate energetic components from chemical munitions
Block 2 – Munitions Washout System (MWS) and Munition Treatment Unit (MTU) operations
• Access mustard agent from munitions and washout munition bodies
• Thermally treat munition bodies to U.S. Army standard of 1,000°F for 15 minutes
Block 3 – Chemical Agent Collection and Neutralization Systems
• Collect and separate chemical agent and washwater
• Neutralize/Hydrolyze mustard agent, converting it to thiodiglycol
Block 4 – Hydrolysate Treatment and Water Recovery
• Treat thiodiglycol using immobilized cell bioreactors (ICBs)
• Recover water for reuse in PCAPP systems
Block 5 – Supplemental Decontamination
• Treat chemical agent contaminated secondary waste to levels that will allow for off-site disposition using a supplementary decontamination unit (SDU) and/or an autoclave
Block 6 – Off-gas Treatment System and Agent Filtration Area
• Control PCAPP facility emissions through an active off-gas treatment system and activated charcoal filtration systems
