Part 150 Noise Study

Part 150 Noise Study

Part 150 of the Federal Aviation Regulations (FAR), “Airport Noise Compatibility Planning,” sets standards for airport operators to use in documenting noise exposure and for establishing programs to minimize noise-related land use incompatibilities. A formal submission to the Federal Aviation Administration (FAA) under Part 150 includes two principal elements:

    (1) A Noise Exposure Map (NEM); and,
    (2) A Noise Compatibility Program (NCP).

 

The City of Portland completed its first Part 150 Study for Portland International Jetport in 1989. The FAA completed its review of the NEM and found it in compliance with Part 150 requirements, publishing a notice of its determination in the Federal Register on 27 March 1990. The FAA approved the Jetport's Noise Compatibility Program in July 1990.

In 2001, the City of Portland began an update of the 11-year old Part 150 study, including a comprehensive evaluation of the previously-approved program elements, development and documentation of an updated NEM, investigation of new alternatives, and preparation of the required NCP documentation.
