(a) An executive order or proclamation declaring a state of disaster:
(1) activates the disaster recovery and rehabilitation aspects of the state emergency management plan applicable to the area subject to the declaration; and
(2) authorizes the deployment and use of any forces to which the plan applies and the use or distribution of any supplies, equipment, and materials or facilities assembled, stockpiled, or arranged to be made available under this chapter or other law relating to disasters.
(b) The preparedness and response aspects of the state emergency management plan are activated as provided by that plan.
(c) During a state of disaster and the following recovery period, the governor is the commander in chief of state agencies, boards, and commissions having emergency responsibilities. To the greatest extent possible, the governor shall delegate or assign command authority by prior arrangement embodied in appropriate executive orders or plans, but this chapter does not restrict the governor's authority to do so by orders issued at the time of the disaster.
