Public Participation Plan For The Chemical Weapons Stockpile Disposal Program U S Army Pueblo Chemical Depot Pueblo Colorado

The purpose of this Public Participation Plan is twofold: (1) to establish ways for sharing knowledge about the chemical weapons disposal mission at Pueblo Chemical Depot; and (2) to allow members of the community surrounding the U.S. Army Pueblo Chemical Depot to communicate openly with the Department of Defense, Program Manager Assembled Chemical Weapons Alternatives the Army, Colorado Department of Public Health and Environment and the systems contractor, Bechtel National, Inc. about chemical weapons stockpile disposal. This document outlines specific public participation strategies for addressing these goals and for maintaining the Public Participation Plan as a flexible, "living" document that can adapt to evolving community needs and concerns.

In 1996, Congress enacted directing the Department of Defense to assess and demonstrate technology alternatives to incineration for destruction of the chemical weapons stored at Pueblo Chemical and Blue Grass Army Depots. Since then, the National Research Council (NRC) has been carrying out evaluations of candidate technologies including reviews of engineering design studies and demonstration testing. Most recently, the NRC was asked by the Army to evaluate designs for pilot plants at Pueblo and Blue Grass. These pilot plants would use chemical neutralization for destroying the chemical agent and the energetics in the munitions stockpiles of these two depots. This report provides the interim assessment of the Pueblo Chemical Agent Destruction Pilot Plant (PCAPP) to permit adjustment of any significant problems as soon as possible. The report presents an analysis of the issues about the current PCAPP design and a series of findings and recommendations about ways to reduce concerns with involve the public more heavily in the process.

The United States has maintained a stockpile of chemical warfare agents and munitions since World War I. The Army leadership has sought outside, unbiased advice on how best to dispose of the stockpile. In 1987, at the request of the Under Secretary of the Army, the National Research Council (NRC) established the Committee on Review and Evaluation of the Army Chemical Stockpile Disposal Program (Stockpile Committee) to provide scientific and technical advice and counsel on the CSDP. This report is concerned with the technology selection for the Pueblo site, where only munitions containing mustard agent are stored. The report assesses a modified baseline process, a slightly simplified version of the baseline incineration system that was used to dispose of mustard munitions on Johnston Island. A second NRC committee is reviewing two neutralization-based technologies for possible use at Pueblo. The evaluation in this report is intended to assist authorities making the selection. It should also help the public and other non-Army stakeholders understand the modified baseline process and make sound judgments about it.

Chemical warfare materiel (CWM) is a collection of diverse items that were used during 60 years of efforts by the United States to develop a capability for conducting chemical warfare. Nonstockpile CWM, which is not included in the current U.S. inventory of chemical munitions, includes buried materiel, recovered materiel, binary chemical weapons, former production facilities, and miscellaneous materiel. CWM that was buried in pits on former military sites is now being dug up as the land is being developed for other purposes. Other CWM is on or near the surface at former test and firing ranges. According to the Chemical Weapons Convention (CWC), which was ratified by the United States in April 1997, nonstockpile CWM items in storage at the time of ratification must be destroyed by 2007. The U.S. Army is the designated executive agent for destroying CWM. Nonstockpile CWM is being handled by the Non-Stockpile Chemical Materiel Program (NSCMP); stockpile CWM is the responsibility of the Chemical Stockpile Disposal Program. Because nonstockpile CWM is stored or buried in many locations, the Army is developing transportable disposal systems that can be moved from site to site as needed. The Army has plans to test prototypes of three transportable systems-the rapid response system (RRS), the munitions management device (MMD), and the explosive destruction system (EDS)-for accessing and destroying a range of nonstockpile chemical agents and militarized industrial chemicals. The RRS is designed to treat recovered chemical agent identification sets (CAIS), which contain small amounts of chemical agents and a variety of highly toxic industrial chemicals. The MMD is designed to treat nonexplosively configured chemical munitions. The EDS is designed to treat munitions containing chemical agents with energetics equivalent to three pounds of TNT or less. These munitions are considered too unstable to be transported or stored. A prototype EDS system has recently been tested in England by non-stockpile program personnel. Although originally proposed for evaluation in this report, no test data were available to the committee on the composition of wastes from the EDS. Therefore, alternative technologies for the destruction of EDS wastes will be discussed in a supplemental report in fall 2001. Treatment of solid wastes, such as metal munition bodies, packing materials, and carbon air filters, were excluded from this report. Review and Evaluation of the Army Non-Stockpile Chemical Materiel Disposal Program: Disposal of Neutralent Wastes evaluates the near-term (1999-2005) application of advanced (nonincineration) technologies, such as from the Army's Assembled Chemical Weapons Assessment Program and the Alternative Technologies and Approaches Project, in a semi-fixed, skid-mounted mode to process Rapid Response System, Munitions Management Device, and Explosive Destruction System liquid neutralization wastes.

Public Law 99-145 and subsequent related legislation requires destruction of the U.S. stockpile of lethal unitary chemical agents and munitions. Furthermore, in 1993 an international treaty, the Chemical Weapons Convention (CWC), was signed by 65 nations, including the United States. The CWC, which set the deadline for completing destruction of chemical weapons as 10 years following ratification by the required number of nations, received the necessary ratifications on April 29,1997. Thus, the international deadline for destruction of chemical weapons as April 29, 2007. The Army Chemical Stockpile Disposal Program has prepared this Final Environmental Impact Statement (FEIS) to assess the potential health and environmental impacts of the construction, operation, and closure of a facility to destroy the chemical agent and munitions stored at Pueblo Chemical Depot (PCD), Colorado. Four alternatives are addressed in this FEIS for possible use in destruction of the PCD stockpile: (1) baseline incineration, which is currently in use by the Army at Deseret Chemical Depot (DCD), Utah and was used by the Johnston Atoll Chemical Agent Disposal System (JACADS) to destroy the entire stockpile on Johnston Atoll; (2) modified incineration, which is based on lessons learned at JACADS and DCD; (3) chemical neutralization followed by biotreatment, a developing technology that would be initially operated as a pilot test facility; and (4) chemical neutralization followed by super critical water oxidation, which is also under development and would be initially operated as a pilot test facility. The latter two alternatives are also being evaluated in a separate DEIS prepared by the Army Assembled Chemical Weapons Assessment Program (ACWA) as part of four chemical neutralization technologies being considered for pilot testing at PCD and three other chemical munitions storage locations. The data and information obtained from testing and full scale operation of the incineration technology, and available data and information from on-going studies of the neutralization technologies provided by ACWA are analyzed and compared to the extent possible in this FEIS.
