Aircraft noise from Ontario International Airport (ONT) is regulated by the FAA, not the city. ONT runs an FAA Part 150 noise compatibility program; federal preemption bars local restrictions on flights.
Because the FAA has exclusive jurisdiction over the national airspace under the Airline Deregulation Act and related federal law, the City of Ontario and residents cannot adopt or enforce municipal ordinances that restrict aircraft takeoffs, landings, or flight paths at Ontario International Airport (ONT). ONT has participated in an FAA Part 150 Noise Compatibility Program that identifies noise-impacted parcels, funds sound insulation of eligible homes and schools, and recommends land-use controls for new development near the airport. The airport also coordinates voluntary noise-abatement procedures with airlines, including preferred runway use during nighttime hours and thrust-management techniques on departure. Residents under the flight paths in Ontario, Rancho Cucamonga, Chino, and parts of Fontana can file noise complaints through the ONT noise hotline and online portal, which are logged and reviewed by airport staff. Complaints do not result in citations against airlines, but the data informs future Part 150 updates and airline outreach.
