TABLE 2-1 Processes and Unit Operations Being Used at PCAPP and BGCAPP

FOAK
Equipment Site(s) Function Note
Rocker shear
machine (RSM)
BGCAPP To separate rocket motors from the warhead, drain agent from the warhead, and shear the warhead into small pieces to be sent to the EBHs This unit will not be contaminated unless a leaking munition contaminates it.
Linear projectile mortar disassembly machine(LMPD) BGCAPP PCAPP To disassemble projectiles and mortars and remove their bursters This unit will not be contaminated unless a leaking munition contaminates it.
Munitions washout station (MWS) BGCAPP PCAPP To remove the burster well from projectiles, drain the chemical agent, and wash out any agent residues This unit and the room will be contaminated.
Energetic bulk hydrolyser EBH) BGCAPP To neutralize energetics and any chemical agent in the metal parts of the rockets and fuzes from projectiles This unit and the explosive containment room will be contaminated.
Metal parts treater (MPT) BGCAPP To decontaminate projectile bodies and secondary waste by heating to over 1000F for more than 15 min The front end of this unit will be in a contaminated atmosphere, but the back end, where the metal parts are removed, will not be in a contaminated area.
Munitions treatment unit(MTU) PCAPP To decontaminate projectile bodies and secondary waste by heating to over 1000°F for more than 15 min The front end of this unit will be in a contaminated atmosphere, but the back end, where the metal parts are removed, will not be in a contaminated area.
Supercritical water oxidation (SCWO) BGCAPP To treat agent energetics hydrolysates before releasing them for final disposal This unit is outside the agent area fence and will be in a noncontaminated area.
Immobilized cell bioreactors(ICBs) PCAPP To treat mustard hydrolysate before releasing it for final disposal This unit is outside the agent area fence and will be in a noncontaminated area.

Vapor screening methods are also used to determine if potentially contaminated workspaces require decontamination during agent changeover or closure activities. In these cases, NRT agent vapor monitors are deployed in unventilated areas to determine if agent vapor levels rise above 1 VSL. While these vapor screening procedures have been used to safely characterize agent contamination of both solid waste materials and structural components at CMA chemical demilitarization sites for the past two decades, they are time consuming and do not directly identify the specific contaminated surface areas that may require further decontamination.
