This regulation establishes the Army Emergency Management Program. The EMP serves as the single integrated emergency management program for the planning, execution, and management of response efforts (designed or intended) to mitigate the effects of an all-hazard incident, to include but not limited to, natural, manmade, and technological disasters, chemical, biological, radiological, nuclear, and high-yield explosive incidents and accidents on or affecting Army installations, facilities, and/or activities. For the purpose of this regulation the term “installation” is used collectively. This regulation facilitates the alignment of the Army with Department of Defense policy and guidance derived in part from Homeland Security Presidential Directive 5 for domestic installations and serves as a baseline for others. This regulation further outlines specific exceptions and caveats for government-owned, contractor-operated plants and installations and other facilities not possessing organic emergency response capabilities.
