The U.S. Army is pilot testing chemical hydrolysis as a method for destroying the chemical agents stockpiled at Aberdeen, Maryland (HD mustard agent), and Newport, Indiana (VX nerve agent). The chemical agents at both locations, which are stored only in bulk ton containers, will be hydrolyzed (using aqueous sodium hydroxide for VX and water for HD) at slightly below the boiling temperature of the solution. The resulting hydrolysate at Aberdeen, which will contain thiodiglycol as the primary reaction product, will be treated by activated sludge biodegradation in sequencing batch reactors to oxidize organic constituents prior to discharge to an on-site federally owned wastewater treatment facility. The hydrolysate at Newport, which will contain a thiol amine and methyl phosphonic acid as the major reaction products, is not readily amenable to treatment by biodegradation. Therefore, organic constituents will be treated using supercritical water oxidation (SCWO). Integrated Design of Alternative Technologies for Bulk-Only Chemical Agent Disposal Facilities focuses on the overarching issues in the process designs integrating individual processing steps, including potential alternative configurations and process safety and reliability. This report reviews the acquisition design packages (ADPs) for the ABCDF and NECDF prepared by Stone and Webster Engineering Company for the U.S. Army.Board on Army Science and Technology, Committee on Review and Evaluation of the Army Chemical Stockpile Disposal ... The committee believes that an investigation of using common designs and equipment could encourage the contractors completing the ADP designs for the ABCDF and ... The Armya#39;s closure team for the Johnston Atoll facility is now studying the process of closure and has published a draft report, Guide to Closure Planning: Draft, Revision 0 (U.S. Army, 1999a).
