Chemical Weapons Disposal

The U.S. Army's chemical stockpile is aging and gradually deteriorating. Its elimination has public, political, and environmental ramifications. The U.S. Department of Defense has designated the Department of the Army as the executive agent responsible for the safe, timely, and effective elimination of the chemical stockpile. This book provides recommendations on the direction the Army should take in pursuing and completing its Chemical Stockpile Disposal Program.

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 incidentsâ€"called chemical eventsâ€"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.

As the result of disposal practices from the early to mid-twentieth century, approximately 250 sites in 40 states, the District of Columbia, and 3 territories are known or suspected to have buried chemical warfare materiel (CWM). Much of this CWM is likely to occur in the form of small finds that necessitate the continuation of the Army's capability to transport treatment systems to disposal locations for destruction. Of greatest concern for the future are sites in residential areas and large sites on legacy military installations. The Army mission regarding the remediation of recovered chemical warfare materiel (RCWM) is turning into a program much larger than the existing munition and hazardous substance cleanup programs. The Army asked the Nation Research Council (NRC) to examine this evolving mission in part because this change is significant and becoming even more prominent as the stockpile destruction is nearing completion. One focus in this report is the current and future status of the Non-Stockpile Chemical Material Project (NSCMP), which now plays a central role in the remediation of recovered chemical warfare materiel and which reports to the Chemical Materials Agency. Remediation of Buried Chemical Warfare Materiel also reviews current supporting technologies for cleanup of CWM sites and surveys organizations involved with remediation of suspected CWM disposal sites to determine current practices and coordination. In this report, potential deficiencies in operational areas based on the review of current supporting technologies for cleanup of CWM sites and develop options for targeted research and development efforts to mitigate potential problem areas are identified.

The U.S. Army Chemical Stockpile Disposal Program was established with the goal of destroying the nation's stockpile of lethal unitary chemical weapons. Since 1990 the U.S. Army has been testing a baseline incineration technology on Johnston Island in the southern Pacific Ocean. Under the planned disposal program, this baseline technology will be imported in the mid to late 1990s to continental United States disposal facilities; construction will include eight stockpile storage sites. In early 1992 the Committee on Alternative Chemical Demilitarization Technologies was formed by the National Research Council to investigate potential alternatives to the baseline technology. This book, the result of its investigation, addresses the use of alternative destruction technologies to replace, partly or wholly, or to be used in addition to the baseline technology. The book considers principal technologies that might be applied to the disposal program, strategies that might be used to manage the stockpile, and combinations of technologies that might be employed.

The main approach adopted by the U.S. Army for destruction of all declared chemical weapon materiel (CWM) is incineration. There has been considerable public opposition to this approach, however, and the Army is developing a mix of fixed site and mobile treatment technologies to dispose of non-stockpile CWM. To assist in this effort, the Army requested NRC to review and evaluate these technologies, and to assess its plans for obtaining regulatory approval for and to involve the public in decisions about the application of those technologies. This book presents an assessment of non-stockpile treatment options and the application of these systems to the non-stockpile inventory, of regulatory and permitting issues, and of the role of the public.

DoD's program to destroy chemical weapons has been controversial from its inception and has experienced delays, cost increases, and mgmt. weaknesses. Concerns over the financial mgmt. of the program surfaced following a review by the DoD Comptroller, which suggested that significant portions of prior years' approp. remained unliquidated. This report discusses the mgmt. of the program -- whether (1) it will meet the Chem. Weapons Convention's time frames within the costs projected, (2) obligations and liquidation of funds approp. for the program have been adequately managed, and (3) the mgmt. structure of the program allows for coordinated account.
