can be complicated by gelling or solidification of the matenal, particularly In the case of mustard, some of which then does not drain from the munition or ton container. These operations result in three separate streams of material that are fed to specially designed destruction systems: an agent stream that is stored in a feed tank prior to injection into the liquid incinerator; a mixed streaTr of energetics, small metal components, and residual agent to be fed to the rotary kiln deactivation furnace system; and large metal parts (e.g., ton containers, spray tanks, artillery projectiles)

As agent flow increases, the fuel flow is decreased to maintain the desired temperature for effective agent destruction. Agent flow to the burner is stopped if this temperature drops below 2550°F.

Gases leaving the secondary chamber of the liquid incinerator or the metal parts furnace afterburner flow to separate dedicated pollution abatement systems for removal of gaseous pollutants and particles to meet emission standards.

The exhaust gas stream from the venturi scrubber enters the scrubber tower below the clear liquor reservoir tray, moves upward through the packed bed section, and exits at the top of the tower after passing through a mist eliminator pad. In the packed bed section, the gas stream contacts a brine solution flowing countercurrently through the bed.

AlLYiliary Systems The dunnage furnace and its pollution abatement system consist of a feed handling system, a pry y chamber, an afterburner, a quench tower, a baghouse separator, an induced draft blower, and a separate exhaust stack. It is designed to burn noncontaminated and contaminated dunnage Mom the munitions processing operations, as well as charcoal and HEPA (highefficier~c~y particulate air)

These systems must be readjusted for each agent type. The ACAMS generates frequent false alarms because it cannot adequately differentiate agent from other commonly encountered organic contaminants (e.g., fuel contaminants, diesel exhaust, antifreeze)

Beyond these expected problems however, and as noted in its OVT reports, the Stockpile Committee believes that the Chemical Stockpile Disposal Program has been understaffed ~ view of the many major technical, regulatory, and public communications issues involved. This has led to administrative oversights and even to short-term technical modifications where longer-term solutions are necessary.
