(i) In accordance with rules or regulations, provide that all law enforcement authorities and other emergency response workers and agencies of other states who may be within this state at the request of the governor or pursuant to state or local mutual-aid agreements or compacts shall have the same authority and possess the same powers, duties, rights, privileges and immunities as are possessed by like law enforcement authorities and emergency response workers and agencies of this state;
