We understand that little infonnation is available on the impact to the downstream pollution abatement system's capability to handle the larger volumes of offgases, temperature spikes, as well as residence times for agent destruction. Also, it is our understanding this approach creates significantly greater quantities of agent within the system than is contemplated within the "baseline" design, leading to the potential for higher amounts of agent to be released during upset conditions, operational malfunctions, and raising serious questions surrounding steady state operational capabilities, given the delicate air flow balance required between the HVAC and combustion systems.

(B) Gelled Rockets: The Commission requests that the Committee assess the validity of the Permit Modification currently under consideration for ANCDF which would allow trial burn processing rates of between 30 to 34 M-55 gelled rockets per hour with no agent draining or explosive reconfiguration prior to processing Em: fully agent loaded, explosive and propellant contained chopped rockets fed to the deactivation furnace.)

In particular the Commission requests the Committee to focus on the acute agent toxicity information included in the NRC report, "Review of Acute Human-Toxicity Estimates for Selected Chemical-Warfare Agents" (National Academy Press, 1997) and the Army's CDEPAT Report, "Review of Existing Toxicity Data and Human Estimates for Selected Chemical Agents and Recommended Human Toxicity Estimates for Selected Chemical Agents and Recommended Human Toxicity Estimates Appropriate for Defending the Soldier" (1994~.

(C) Hazardous Waste Combustion: The Commission requests the Committee include a review of the 1999 National Research Council report, Waste Incineration and Public Health, which made art assessment of the relationship between hazardous waste combustion and human health; the design, citing and operating conditions of combustion facilities; an overview of human exposure to pollutants the risk assessments and other methodologies used to measure potential exposures.

Identifying Events to be Reviewed: There is a high degree of skepticism in communities where chemical stockpiles are located that many "incidents" are not being disclosed to the public and that the decision by PMCD on whether or not to have these incidents formally characterized as "chemical events" is often based on the potential negative impact on the program's image rather than the actual circumstances surrounding We incidences. The Commission therefore requests that the Committee insure the lists of "incidents" that have complied by these citizen groups be compared with the list of "Chemical Events" provided to Me Committee by PMCD.

(0 2001: Public infonnation on TOCDF operations has decreased noticeably since the September 2000 House Armed Services Procurement Subcommittee Hearings on the May 8~, 2000, agent release at TOCDF. Information from sources at TOCDF indicate continued DFS feed gate problems, several slag fires in the LIC and other possible incidents of potential agent releases.

Report: The Commission requests the Committee review the more than 3000 design charges noted in the AAA Report with particular attention to the lack of assessment of the effect of these design changes on operations. Modifying components within He overall design of the plants without consideration of their impacts on up or down stream functional capability would appear to contradict sound management policy and could be potentially dangerous from an operational standpoint.
