If the Administrator determines that noise mitigation flight procedures are consistent with safe and efficient use of the navigable airspace, the Administrator may commit, at the request of the airport sponsor and in a manner consistent with applicable Federal law, to prescribing such procedures in any record of decision approving the project.(b) MODIFICATION.-Notwithstanding any commitment by the Administrator under subsection (a), the Administrator may initiate changes to such procedures if necessary to maintain safety and efficiency in light of new information or changed circumstances.Added Pub.
