Evaluation of Demonstration Test Results of Alternative Technologies for Demilitarization of Assembled Chemical Weapons: A Supplemental Review for Demonstration II Preface The United States has been in the process of destroying its chemical munitions for well over a decade. Initially, the U.S. Army, guided by recommendations from the National Research Council (NRC), decided to use incineration as its destruction method at all sites. However, citizens in some states with stockpile storage sites oppose incineration on the grounds that the exact nature of the effluents escaping from the stacks cannot be determined. The Army has continued to pursue incineration at four of the eight storage sites in the continental United States where that process seemed appropriate. Nevertheless, influenced by growing public opposition to incineration and the 1996 NRC report Review and Evaluation of Alternative Chemical Disposal Technologies, the Army has also been developing technologies based on chemical hydrolysis for the remaining sites. These processes will be used to destroy the VX nerve agent stored at Newport, Indiana, and the mustard agent stored at Aberdeen, Maryland, both of which are stored only in bulk one-ton containers and not in assembled munitions. In 1996, persuaded by public opposition in Lexington, Kentucky, and Pueblo, Colorado, Congress enacted Public Law 104–201, which instructed the U.S. Department of Defense (DoD) to “conduct an assessment of the chemical demilitarization program for destruction of assembled chemical munitions and of the alternative demilitarization technologies and processes (other than incineration) that could be used for the destruction of the lethal chemical agents that are associated with these munitions.” In response, the Army established the program manager for the Assembled Chemical Weapons Assessment (PMACWA). In Public Law 104–208, the PMACWA was required to “identify and demonstrate not less than two alternatives to the baseline incineration process for the demilitarization of assembled chemical weapons.” During the first phase of the Assembled Chemical Weapons Assessment (ACWA) program, seven technologies were evaluated. Three of them proceeded to demonstration testing (Demo I) and one was dropped completely. In August 1999, the PMACWA selected two of the Demo I technologies as candidates for the destruction of the assembled munitions weapons at Pueblo Chemical Depot. The two packages, General Atomics Total Solution (GATS) and Parsons/Honeywell (formerly Parsons-Allied Signal) water hydrolysis of explosives and agent technology (WHEAT), were advanced to the engineering design study phase of the ACWA program. The PMACWA has involved the citizen stakeholders in every aspect of the program, including the procurement process. The Keystone Center, a nonprofit organization, was hired to facilitate public involvement through a process known as the Dialogue, which has become a model for public involvement in matters of public concern.1 The Congress mandated that the Army coordinate with the NRC during the ACWA program. In response, the NRC established the Committee on Review and Evaluation of Alternative Technologies for Demilitarization of Assembled Chemical Weapons (ACW I committee) in 1997 to oversee this program. The question before the committee was not whether incineration was an adequate technology for destroying assembled chemical weapons but whether other chemical processes acceptable to the stakeholders could be 1 The U.S. Department of Energy and the National Aeronautics and Space Administration have both adopted this approach. For example, at the NASA Jet Propulsion Laboratory, the Dialogue process will be used in developing a Mars sample-return mission, which is scheduled for 2012.

Evaluation of Demonstration Test Results of Alternative Technologies for Demilitarization of Assembled Chemical Weapons: A Supplemental Review for Demonstration II used. The second NRC committee (ACW II committee) was established in the spring of 2000 to evaluate the two engineering design studies for the destruction facilities at Pueblo, Colorado, and Richmond, Kentucky, and to evaluate the demonstration testing of the three technology packages that had not been selected for those sites or for previous demonstration testing. Although the PMACWA had no intention of demonstrating these three technologies, Public Law 106–79 (2000) mandated that the PMACWA “conduct evaluations of [the] three additional alternative technologies under the ACWA program.” Furthermore, the PMACWA was directed to “proceed under the same guidelines as contained in Public Law 104–208 and continue to use the Dialogue process and Citizens’ Advisory Technical Team and their consultants.” Accordingly, the PMACWA initiated a program commonly referred to as Demo II to demonstrate the three technologies (AEA SILVER II™, the Foster Wheeler/Eco Logic/ Kvaerner integrated demilitarization process, and Teledyne-Commodore’s solvated electron process) that had not been selected during the first phase. The ACW II committee was asked to determine if and how the Demo II results affected its commentary, findings, and recommendations and the steps that were suggested for implementation in the ACW I report. This report presents the committee’s evaluation of the second set of demonstration tests. I wish to gratefully acknowledge the hard work of members of the ACW II committee, all of whom served as volunteers and provided the expertise necessary to carry out this enormous task. They gave relentlessly and unselfishly of their time and effort throughout the study. Their areas of expertise included chemical processing, biological remediation, environmental regulations and permitting, energetic materials, and public acceptance. Committee members attended plenary meetings, visited the technology providers’ headquarters and test sites, observed design-review sessions, and studied the extensive literature, including engineering charts and diagrams, provided by the technology providers. On behalf of the committee, I would like to also express appreciation for the extensive support of the Army ACWA team and its interactions with stakeholders and the Dialogue, particularly the group’s Citizens Advisory Technical Team, whose members attended all open meetings of the committee and shared information and views with it. The committee also appreciated the openness and cordiality of the representatives of the technology providers. They and the Army provided early drafts of their test reports and other documentation to facilitate the committee’s evaluation. A study such as this requires extensive logistic support; the committee is indebted to the NRC staff for their assistance. I would particularly like to acknowledge the close working relationship I had with the NRC study director, Patricia Paulette. We worked as a team in leading this study. We spoke on the phone daily and e-mailed each other incessantly. The efforts of William Campbell, who took extensive notes and provided real-time report corrections at all our meetings as well as suggestions on how to best organize the report, were invaluable to the committee and to me. Gwen Roby provided the logistic support that enabled us to concentrate on our task. I am also indebted to my colleagues in the Chemistry Department at the University of Southern California who willingly took over my teaching duties while I traveled on behalf of this study.

The level for mustard agent is 3.0 mg per cubic meter in air. Materials classified as 3X may be handled by qualified plant workers using appropriate procedures but are not releasable to the environment or for general public reuse. In specific cases in which approval has been granted, a 3X material may be shipped to an approved hazardous waste treatment facility for disposal in a landfill or for further treatment. 5X level Treatment of solids to a 5X decontamination level is accomplished by holding a material at 1,000°F for 15 minutes. This treatment results in completely decontaminated material that can be released for general use or sold (e.g., as scrap metal) to the general public in accordance with applicable federal, state, and local regulations. 5X treatment unit This unit is used to heat chemical solid waste materials to a level of decontamination where no residual contamination is detectable.
