Preparation by Federal Agencies of Civil Defense Emergency Plans. (White House (President Harry S. Truman), April 17, 1952) "In 1952, FCDA was given a key role in assisting federal agencies with planning for service provision and continued functioning during emergencies (now referred to as "continuity of operations"). President Truman issued an executive order directing federal departments and agencies to consult with FCDA and to "prepare plans for providing [their] personnel, materials, facilities, and services... during... a civil defense emergency" and plans for maintaining continuity of government during such a time". (CRS, Federal Emergency Management and Homeland Security Organization: Historical Developments and Legislative Options, 1Jun2006) "...E.O. 10346 mandated that each federal department or agency should cooperate with the Federal Civil Defense Administration to prepare plans for providing its personnel, materials, facilities, and services during the existence of a Civil Defense Emergency.. The plans were to be designed to include continuity of department and agency operations and coordination of such arrangements with other national, state, and local civil defense plans. No consolidated emergency response plan appeared until 1958, with final issuance as a document signed by President Lyndon B. Johnson in 1964 under the auspices of the Office of Emergency Preparedness (originally, the Office of Emergency Management in WWII, and then the Office of Emergency Planning from 1958-61)".
