Closing a runway is an action tied to who owns and operates the airfield. The airport management, or for military facilities the military operations office, has the legal authority to declare a runway closed. They determine when conditions make a runway unsafe and must coordinate with air traffic control and issue the proper notices (such as a NOTAM) to ensure pilots know the closure. The FAA regional office creates rules and oversees safety standards, but it does not unilaterally close a specific runway. The air traffic control tower supervisor can manage traffic and may implement temporary restrictions to maintain safety, but the authority to permanently or officially close a runway rests with the airport’s management. An advisory body like the airport operations committee can propose closures, but it cannot enact a closure without the airport management’s authorization.
