"States immediately threatened with impact from an existing hurricane or typhoon will be considered for an emergency declaration when, in addition to the State request complying with requirements set forth in 44 CFR 206.35, FEMA determines the following three requirements are also met: The National Weather Service determines that the State, or a portion thereof, is threatened by landfall of a major hurricane or typhoon, AND: (1) The Governor has declared a State of Emergency, AND: (2) Either: (2.a) The State, or any jurisdiction(s) thereof, has issued mandatory evacuation orders for three or more counties/parishes, or any geographical area with a combined population of more than 100,000 residents, OR: (2.b) The declaration is necessary to provide direct federal assistance (e.g., teams, equipment, supplies) to meet critical emergency protection requirements before landfall, other than pre-positioning, that would overwhelm the capability or capacity of State resources. States immediately threatened by any other natural or man-made incident that threatens such destruction as could result in a major disaster (except fires, for which emergency assistance is provided under the provisions of the Fire Management Assistance Grant program in 44 CFR part 204) will be considered for an emergency declaration when, in addition to the State request complying with requirements set forth in 44 CFR 206.35, FEMA determines the following three requirements are also met: (1) A qualified Federal government agency - acknowledged as a national authority in a specific incident field (e.g., United States Geological Survey for seismic incidents, the National Weather Service for tsunamis, the Nuclear Regulatory Commission for nuclear power plants, or the Department of Homeland Security for acts of terrorism) - determines or affirms that a catastrophic incident is immediately imminent, AND: (2) The Governor has declared a State of Emergency, AND: (3) Either: (2.a) The State, or any jurisdiction(s) thereof, has issued mandatory evacuation orders for three or more counties/parishes, or any geographical area with a combined population of more than 100,000 residents, OR: (2.b) FEMA determines that the scope of the potential or projected incident is such that it would or could result in such damage as would constitute a catastrophe; AND the declaration is necessary to provide direct federal assistance (e.g., teams, equipment, supplies) to meet critical emergency protection requirements before impact, other than pre-positioning, that would overwhelm the capability or capacity of State resources".
