The George W. Bush administration put the Continuity of Operations plan into effect for the first time directly following the September 11 attacks . Their implementation involved a rotating staff of 75 to 150 senior officials and other government workers from every federal executive department and other parts of the executive branch in two secure bunkers on the East Coast . Friends , family , and co-workers were only able to reach them through a toll-free number and personal extensions . The Bush administration did not acknowledge the implementation of the COG plan until March 1 , 2002
