(a) "Emergency resources management plan" shall mean that plan prepared by the Idaho emergency resources planning committee, approved by the federal office of emergency planning and adopted by the governor, which sets forth the organization, administration, and functions for the emergency management by the state government of essential resources and economic stabilization within the state. Such plan shall provide an emergency organization and emergency administrative policies and procedures for the conservation, allocation, distribution, and use of essential resources available to the state following a civil defense emergency such as an attack upon the United States. It shall be supplemental to the national plan for emergency preparedness adopted by the President of the United States, and shall become operative upon the establishment of a civil defense emergency. To the extent that the federal government is either incapable of or not prepared to conduct its emergency resources management program, the state will substitute for and replace the federal program until such time as the federal program becomes effective in the state.
