Evaluation of Chemical Events at Army Chemical Agent Disposal Facilities

For over a decade the Army has been carrying out a program aimed at the destruction of accumulated chemical weapons stored at several sites. While destruction by incineration has been successful, several incidents—called chemical events—occurred during the disposal process or decontamination activities that raised some public concerns about the safety of operations of three third generation incineration facilities. As a result, the Congress asked the NRC to investigate whether the incidents provide information useful to help ensure safe operation of the future sites. This book presents an analysis of causes of and responses to past chemical events, implications of such events for ongoing and future demilitarization activities, and recommendations for preparing for future events.Table of ContentsFront MatterExecutive Summary1 The Chemical Demilitarization Challenge2 Causal Factors in Events at Chemical Demilitarization Facilities3 Responses to Chemical Events at Baseline Chemical Demilitarization Facilities4 Implications of Past Chemical Events for Ongoing and Future Chemical Demilitarization Activities5 Preparing for Potential Future Chemical Events at Baseline Chemical Demilitarization Facilities6 Findings and RecommendationsReferencesAppendix A Specific Design Features of the Toole Chemical Agent Disposal Facility Baseline Incineration SystemAppendix B Chronicle of Chemical Events and Other Occurrences at TOCDF and JACADS As Identified by PMCDAppendix C List of Individual Incidents from the Chemical Weapons Working GroupAppendix D List of Individual Incidents from Calhoun County Commission, Anniston, AlabamaAppendix E Additional Information Concerning RiskAppendix F Causal Tree Analysis of December 3-5, 2000, Event at JACADSAppendix G Memorandum of Understanding Between Deseret Chemical Depot and Tooele County for Information ExchangeAppendix H Biographical Sketches of Committee MembersAppendix I Committee Meetings
