Pt. 151 14 CFR Ch. I (1-1-19 Edition) the operation of aircraft to reduce exposure of individuals (or specific noise sensitive areas) to noise in the area around the airport. (5) The implementation of any restriction on the use of airport by any type or class of aircraft based on the noise characteristics of those aircraft. Such restrictions may include, but are not limited to - (i) Denial of use of the airport to aircraft types or classes which do not meet Federal noise standards; (ii) Capacity limitations based on the relative noisiness of different types of aircraft; (iii) Requirement that aircraft using the airport must use noise abatement takeoff or approach procedures previously approved as safe by the FAA; (iv) Landing fees based on FAA certificated or estimated noise emission levels or on time of arrival; and (v) Partial or complete curfews. (6) Other actions or combinations of actions which would have a beneficial noise control or abatement impact on the public. (7) Other actions recommended for analysis by the FAA for the specific airport. (c) For those alternatives selected for implementation, the program must identify the agency or agencies responsible for such implementation, whether those agencies have agreed to the implementation, and the approximate schedule agreed upon. Sec. B150.9 Equivalent programs. (a) Notwithstanding any other provision of this part, noise compatibility programs prepared in connection with studies which were either Federally funded or Federally approved and commenced before October 1, 1981, are not required to be modified to contain the following items: (1) Flight tracks. (2) A noise contour of Ldn 70 dB resulting from aircraft operations and data related to the Ldn 70 dB contour. When determinations on land use compatibility using Table 1 of appendix A differ between Ldn 65-70 dB and Ldn 70-75 dB, the determinations should either use the more conservative Ldn 70-75 dB column or reflect determinations based on local needs and values. (3) The categorization of alternatives pursuant to Sec. B150.7(a), although the persons responsible for implementation of each measure in the program must still be identified in accordance with Section 150.23(e)(8). (4) Use of ambient noise to determine land use compatibility. (b) Previously prepared noise compatibility program documentation may be supplemented to include these and other program requirements which have not been excepted.
