Federal Aviation Regulation (FAR) Part 150, “Airport Noise Compatibility Planning,” provides the methodology and procedures to be used in preparing aircraft noise exposure maps and developing airport land use compatibility programs. Conducting a Part 150 study qualifies airport operators for Federal Aviation Administration (FAA) grant funds for homeowner assistance programs. Upon approval of the Part 150 study for Baltimore/Washington International Thurgood Marshall Airport by the FAA, funding will be available to the Maryland Aviation Administration (MAA) for programs such as soundproofing, resale assurance, or the purchase of homes and schools where aircraft noise exceeds federal standards.
