From the Document: "In the Post-Katrina Emergency Management Reform Act (PKEMRA, P.L. 109-295), Congress required the President to develop a national preparedness system -- that includes planning and implementation guidance and processes -- with a national preparedness goal. It also directed the FEMA Administrator to develop 'guidelines to define risk-based target capabilities for Federal, State, local, and tribal government preparedness.'"
