DHS selected Manhattan, Kansas, as the site for the new NBAF after an extensive site-selection process that involved an environmental impact statement. The Government Accountability Office (GAO) raised concerns about DHS's analysis of the potential spread of foot-and-mouth disease virus (FMDv), one of the most serious foreign animal disease threats. Congress directed DHS to conduct a site-specific risk assessment (SSRA) for the NBAF, instructed the National Research Council (NRC) to independently evaluate the SSRA, and prohibited obligation of NBAF construction funds until the NRC review was complete.
Congress mandated that DHS revise its SSRA to address shortcomings of the 2010 SSRA, directed the NRC to evaluate the updated SSRA (uSSRA), and again prohibited obligation of construction funds until the completion of the second review. The scope for both of these SSRA reports addressed accidental release of pathogens from the NBAF in Manhattan, Kansas and excluded terrorist acts and malicious threats from its risk assessments. Evaluation of the Updated Site-Specific Risk Assessment for the National Bio- and Agro-Defense Facility in Manhattan, Kansas is the evaluation of the final uSSRA.
