"In certain scenarios, a PFO may be pre-designated by the Secretary of Homeland Security to facilitate Federal domestic incident planning and coordination at the local level outside the context of a specific threat or incident. A PFO also may be designated in a pre-incident mode for a specific geographic area based on threat and other considerations. In the event of a single incident with national implications or in the case of multiple incidents, a national-level PFO may be designated to provide overall coordination of Federal incident management activities. The PFO may further delegate duties to a Deputy PFO, the FCO or other designated Federal official as appropriate to facilitate incident management span of control or after an event transitions to long-term recovery and/or cleanup operations".
