14 CFR Part 150 sets out the federal rules for airport noise compatibility planning, establishing how airports must measure noise, map affected areas, and develop programs to reduce conflicts between aircraft noise and nearby land uses. It defines key terms such as day-night average sound level (DNL), compatible and noncompatible land use, and noise exposure maps, and it outlines the process by which the FAA reviews and approves or disapproves airport noise compatibility programs. Importantly, FAA approval of such a program does not itself commit federal funding or authorize specific actions without further environmental review.

San Francisco International Airport (SFO) submitted formal comments to the FAA on May 9, 2025, opposing proposed changes to Airport Improvement Program (AIP) Grant Assurances, arguing the modifications lack legal clarity and were being rushed into effect mid-fiscal year. SFO raised concerns that incorporating certain presidential Executive Orders into grant conditions is legally problematic, as those orders are directed at federal agencies rather than state or local governments. The airport requested a 30-day comment period extension and asked that any new requirements not take effect before the start of fiscal year 2026.
