GAO reviewed the Federal Emergency Management Agency’s (FEMA) actions to improve its capabilities to respond to terrorist incidents based on its response to lessons learned from the Oklahoma City bombing, requirements in Presidential Decision Directives 39 and 62, and its own guidance. Specifically, GAO determined the extent to which FEMA has (1) incorporated the lessons learned from the aftermath of the Oklahoma City bombing, (2) ensured the preparedness of states and federal agencies to respond to terrorist incidents, and (3) ensured that states’ plans are tested through exercises. GAO found that FEMA (1) has made across the board improvements in those areas identified as needing action after the Oklahoma City bombing, (2) updated the Federal Response Plan to address how federal agencies, states, and localities would work together to respond to an act of terrorism, and (3) assessed states’ capabilities for consequence management in 1995 and set up a system to continue monitoring those capabilities.
