The Department of Homeland Security completed a Site-Specific Biosafety and Biosecurity Mitigation Risk Assessment (SSRA) (PDF, 463 pages - 37 MB) in June 2010, and submitted it to the National Academy of Sciences for review. The SSRA was reprinted in October 2010 with Academy updates included. Appendices referenced in the SSRA are available in the SSRA Appendices (PDF, 290 pages - 43 MB) document.
The National Academy of Sciences reviewed the SSRA and found the site-specific risk analysis to be an important "first step in an iterative process aimed at identifying and minimizing risk" and supported the need for the capabilities NBAF provides. With a risk assessment completed at such an unusually early stage in facility design, DHS has taken proactive steps to build in risk mitigation and management measures for NBAF. Homeland Security issued a fact sheet (PDF, 2 pages - 132 KB) summarizing the SSRA process.
As part of its on-going risk management process and to comply with recent Congressional requirements, the Department of Homeland Security (DHS) updated the NBAF SSRA by incorporating recommendations from the NRC and the updated design plans. The Updated SSRA includes an Executive Summary (PDF, 66 pages - 3.3MB), Volume I (PDF, 432 pages - 95.4MB), Volume II (PDF, 491 pages - 19.7MB), and Appendices (PDF, 360 pages - 20.0MB).
The Updated SSRA satisfies the Congressional requirements for demonstrating how calculated risks have been significantly reduced by incorporating mitigation measures into the risk assessment and updating the analysis to allow for a cumulative risk calculation.
The Department will not build or operate the NBAF unless it can be done in a safe manner. The Department will continue to work with USDA and Centers for Disease Control (CDC) to ensure all recommendations from the SSRA are properly implemented and all biosafety and biosecurity requirements have been met. No permits will be issued by USDA and/or CDC until all requirements are met.
