named the Kansas site as the preferred location for the NBAF. On January 16, 2009, the record of decision was published in the Federal Register. After the Manhattan location was finalized in 2009, the Government Accountability Office questioned the choice of location in a July 2010 draft report, because it is located on the mainland U.S. unlike the current Plum Island facility. This led to a further "site-specific" study of the facility's safety, issued by DHS in 2012. Risk assessments Plum Island is the only research facility currently studying foot-and-mouth disease (FMD) in the U.S. In 2008, the Government Accountability Office (GAO) was asked to evaluate the evidence DHS used to support its determinations that FMD work can be done safely on the U.S. mainland, whether an island location provides any additional protection over and above that provided by modern high containment laboratories on the mainland, and the economic consequences of an FMD outbreak on the U.S. mainland. Because of concerns raised by the GAO in 2010, Congress instructed DHS to complete a "site-specific biosafety and biosecurity risk assessment." It also directed the National Academy of Sciences to appoint a committee of the National Research Council (NRC) to conduct an independent evaluation of this site-specific risk analysis to determine its adequacy and validity. Congress would not release construction funds until these were completed and evaluated. DHS completed the requisite site-specific risk analysis (SSRA) in March 2012, and the NRC committee issued its evaluation of the SSRA in June 2012. Site construction The facility is under construction. Preliminary clearing and grading of the proposed site began in 2010, construction on the site's power plant began in 2013, and construction of the lab began in 2015. On January 2, 2013, the Department of Homeland Security accepted a transfer of land from the State of Kansas for the site of the facility. In March 2013, a contract was awarded for the construction of a central utility plant for the NBAF. An official groundbreaking ceremony for construction of the power plant was held on May 28, 2013. The federal government budgeted $440 million for construction and related work on the NBAF under the Consolidated Appropriations Act of 2014, signed into law on January 17, 2014. President Barack Obama included an additional $300 million for construction in his proposed 2015 budget, constituting the final installment of federal construction spending for the facility. This funding was
