Destruction of Chemical Munitions at Blue Grass Army Depot, Kentucky - Final Environmental Impact Statement, Volume I (Main Report, Appendicies A-J)

“Destruction of Chemical Munitions at Blue Grass Army Depot, Kentucky – Final Environmental Impact Statement – Volume I (Main Report and Appendices A-J)” (see also “Volume II – Appendix K”) - 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 is 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 Blue Grass Army Depot (BGAD), Kentucky. Four alternatives are addressed in this FEIS for possible use in destruction of the BGAD 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) chemical neutralization followed by supercritical water oxidation, a developing technology that would be initially operated as a pilot test facility; (3) chemical neutralization followed by supercritical water oxidation and gas phase chemical reduction, a developing technology that would be initially operated as a pilot test facility; and (4) electrochemical oxidation, which is also under development and would be initially operated as a pilot test facility. The latter three alternatives have also been evaluated in a separate EIS prepared by the Army Assembled Chemical Weapons Assessment Program (ACWA) as part of four chemical neutralization technologies being considered for pilot testing at BGAD 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 technologies provided by ACWA are analyzed and compared to the extent possible in this FEIS.
