From page 183...
... The following findings and recommendations are based on the AltTech Panel' s in-depth technical evaluation and assessment of five alternative technologies: catalytic extraction, electrochemical oxidation, gasphase chemical reduction, stand-alone neutralization or neutralization followed by biodegradation for HD, and stand-alone neutralization or neutralization followed by biodegradation for VX. The panel evaluated these technologies for the particular application of destroying HD blister agent or VX nerve agent stored in bulk containers.

... Specific Finding 3. The panel determined that the development status of the technologies assessed and the lack of long-term experience with their use for the destruction of chemical agent necessitate a comprehensive design review of any selected technology prior to the construction of a pilot plant.

... Before any technology is implemented at a stockpile site, an independent, sitespecific quantitative risk assessment and a health and inherent process safety, which includes consideration of the required safeguards or engineering controls, the potential for process upsets, the requirements for process control interlocking, reliability, and the hazard inventory technical maturity, as shown by such factors as the scale of demonstrated ability to process agent and commercial industrial experience with the equipment, systems, and processes that would be required for an agent-destruction facility process simplicity, judged by such factors as the number of unit operations required and the ease of scale-up to a full-production facility Based on these priorities, the panel reached consensus on the following findings and recommendations on alternative technologies to be pilot-tested for agent destruction at the Aberdeen and Newport sites. HO at Aberdeen Specific Finding 6.

... it is possible, EVALUATION OFALTERNATIVE TECHNOLOGIES although not yet established by adequate testing, that the hydrolysate has sufficiently low toxicity associated with its organic products that complete biodegradation prior to discharge may not be necessary. Furthermore, treatment of VX hydrolysate by existing commercial TSDF processes other than biodegradation is likely to be possible.

... Recommendation S if successful off-site treatment of VX hydrolysate at an existing TSDF is not confirmed by appropriate treatability studies, and successful onsite treatment of VX hydrolysate with existing commercial processes cannot be demonstrated, then the Army should pilot-test the electrochemical oxidation of VX for potential use at the Newport site.
