The South Carolina Firefighter Mobilization Oversight Committee shall establish the South Carolina Firefighter Mobilization Plan. The purpose of the plan is to provide for responding firefighting and rescue resources from one part of the State to another part of the State or from one state to another state. The plan is operative (1) under emergencies declared by the Governor or by the President of the United States, (2) when a local fire chief needs additional resources after existing mutual aid agreements have been utilized, or (3) when another state requests assistance in dealing with an emergency when a state mutual aid agreement exists between South Carolina and the other state. In addition, the plan operates and is a part of the State Emergency Response Plan.
