These filter trays are placed in waste incineration of used unexposed carbon from Banks 3 through 6 of containers that are fed to the MPF. Since the carbon the HVAC filter units to Calgon Carbon Corporation would not be completely oxidized at the end of normal for reactivation.

Recommendation 7-4. Although carbon can be successfully treated in the metal parts furnace, on-site Recommendation 7-5b. The Chemical Materials disposal treatment of exposed carbon in the metal parts Agency should review the planned sampling and furnace should be limited to small quantities of exposed analysis procedures for carbon that will be treated in the carbon -- from, for example, agent collection system fil- autoclave. This would ensure that they are appropriate ter units and M-40 protective mask canisters -- because for achieving the postautoclave processing condition the time required to completely oxidize all of the of the carbon and that they can reliably measure agent exposed carbon generated at a chemical agent disposal concentrations at levels required by the permit for offfacility would seriously extend the disposal operations site shipment to a hazardous waste disposal facility.
