Drawing on previous National Academies of Sciences, Engineering, and Medicine reports that addressed the closure of chemical agent disposal facilities, and on information that will be provided by the Program Executive Office for Assembled Chemical Weapons Alternatives (PEO ACWA), the committee will:

• Identify lessons learned, significant risks, or issues that arose during the closure of Chemical Materials Agency (CMA) chemical agent disposal facilities that would be applicable to the closure of the Pueblo Chemical Agent Destruction Pilot Plant (PCAPP) and the Blue Grass Chemical Agent Destruction Pilot Plant (BGCAPP), including the treatment of hydrolysates and liquid secondary wastes. Aspects of closure to be covered will include, but not necessarily be limited to, the deconstruction of large and complex industrial facilities, decontamination, environmental permitting and safety, the handling and disposal of hazardous materials, and occupational safety and health.
• Make findings and recommendations to assist PEO ACWA in defining best practices and approaches for the closure of PCAPP and BGCAPP.
