U.S. Army records, primarily as presented in the STS Lot Book and end-of-campaign reports for JACADS and TOCDF, are insufficient to quantify the observations and effects on stockpile disposal operations attributable to the processing of anomalous munitions and containers.

iSAIC responses to committee degradation risk questions, August 14, 2002. 37 This is expressed in the QRA analysis by extending the duration of the agent campaigns for leaker processing.2 Examples of risks associated with leaking M55 rockets that were addressed in the QRAs include those arising from overpacking operations during storage.3 Also, because overpacked munitions involve more extensive handling during demilitarization, they lengthen the disposal campaigns, thus increasing the time in storage of the remaining munitions.

Corrective actions employed to address anomaly conditions of all types include the following: - Modification of process rate, sequence, schedule, and standard operating procedures, as required, to minimize risk and mechanical disruption; - Modification of the RCRA permit to enable a facility to handle an anomaly efficiently (by, for example, allowing a different processing sequence) ; Modification and/or replacement of equipment; Revisions of operator training and improvement of procedures; Notification and education of stakeholders; and Rejection, isolation, and eventual special processing of munitions.

High So/ids Content HO Mustard agent that has a high solids content requires adjustment of the processing rate to reflect extended agent drain time, modification of the RCRA permit to allow increased agent loading in the MPF, and destruction of the agent along with the body of the munition in the MPF. Among the problems encountered was damage to the multipurpose demilitarization machine (MDM)

improper Fabrication of Burster Tube Improper burster tube fabrication is an anomaly that shows up in numerous ways tubes welded into the munitions casing, imperfect agent cavity seal due to burster tube roughness, tubes installed upside down, out-of-specification burster tube fabrication, the use of aluminum tubes instead of specified steel, and overlong tubes. Corrective action involves routine processing where possible but processing as a reject munition when required.

DPE suits used during nonroutine processing of exceptional munitions, such as overpacked leakers, are intended to minimize potential agent exposure. However, additional risk is imposed through the need for protective clothing.

Very little, if any, quantitative data exist on the effects of anomalous stockpile items on the schedule or cost of the stockpile disposal program. There is, however, significant anecdotal information that anomalous munitions and containers extend processing schedules and increase costs.

In parallel with the planning, construction, and operation of stockpile disposal facilities, the Army has funded the Chemical Stockpile Emergency Preparedness Program (CSEPP)
