The Federal Emergency Management Agency (FEMA) assists states and localities overwhelmed by, or at risk from, disasters. FEMA also co-ordinates emergency management activities and planning for the continuity of government should national security be threatened. Since 1979 FEMA has administered a range of authorities that enable the agency to serve as the primary source of federal, technical, and financial assistance for emergency management. Among the types of aid provided through FEMA programs are grants and material to help disaster victims meet pressing needs such as food and shelter, education and training programs to improve the response capabilities of non-federal officials, and mobile communications equipment. FEMA exercises little regulatory authority, but directives that underlie the agency''s mission authorise the agency to establish standards for reconstruction of buildings after a disaster declaration is issued, for the construction of federal buildings in earthquake-prone areas, and for the operation of first responder equipment. FEMA has responded to, and has helped communities prepare for, terrorist attacks in the United States. The Office of Homeland Security (OHS), established by President Bush subsequent to the attacks in 2001, has a similar, but more encompassing, mission related to disasters caused by terrorist actions. Congressional debate on the contours and framework for federal administration of homeland security might include consideration of FEMA''s mission, the extent to which that mission overlaps with the assignments given the new OHS, and a new structure or set of authorities for that agency.
