Scope and purpose. Sec. B150.3 Requirement for noise map. Sec.
B150.5 Program standards. Sec. B150.7 Analysis of program
alternatives. Sec. B150.9 Equivalent programs. Sec. B150.1 Scope
and purpose.
(a) This appendix prescribes the content and the methods for
developing noise compatibility programs authorized under this part.
Each program must set forth the measures which the airport operator
(or other person or agency responsible) has taken, or proposes to
take, for the reduction of existing noncompatible land uses and the
prevention of the introduction of additional noncompatible land
uses within the area covered by the noise exposure map submitted by
the operator.
(b) The purpose of a noise compatibility program is:
(1) To promote a planning process through which the airport
operator can examine and analyze the noise impact created by the
operation of an airport, as well as the costs and benefits
associated with various alternative noise reduction techniques, and
the responsible impacted land use control jurisdictions can examine
existing and forecast areas of noncompatibility and consider
actions to reduce noncompatible uses.
(2) To bring together through public participation, agency
coordination, and overall cooperation, all interested parties with
their respective authorities and obligations, thereby facilitating
the creation of an agreed upon noise abatement plan especially
suited to the individual airport location while at the same time
not unduly affecting the national air transportation system.
(3) To develop comprehensive and implementable noise reduction
techniques and land use controls which, to the maximum extent
feasible, will confine severe aircraft YDNL values of Ldn 75 dB or
greater to areas included within the airport boundary and will
establish and maintain compatible land uses in the areas affected
by noise between the Ldn 65 and 75 dB contours.
Sec. B150.3 Requirement for noise map.
(a) It is required that a current and complete noise exposure
map and its supporting documentation as found in compliance with
the applicable requirements by the FAA, per § 150.21(c) be included
in each noise compatibility program:
(1) To identify existing and future noncompatible land uses,
based on airport operation and off-airport land uses, which have
generated the need to develop a program.
(2) To identify changes in noncompatible uses to be derived from
proposed program measures.
(b) If the proposed noise compatibility program would yield maps
differing from those previously submitted to FAA, the program shall
be accompanied by appropriately revised maps. Such revisions must
be prepared in accordance with the requirements of Sec. A150.101(e)
of appendix A and will be accepted by FAA in accordance with §
150.35(f).
Sec. B150.5 Program standards.
Based upon the airport noise exposure and noncompatible land
uses identified in the map, the airport operator shall evaluate the
several alternative noise control actions and develop a noise
compatibility program which -
(a) Reduces existing noncompatible uses and prevents or reduces
the probability of the establishment of additional noncompatible
uses;
(b) Does not impose undue burden on interstate and foreign
commerce;
(c) Provides for revision in accordance with § 150.23 of this
part.
(d) Is not unjustly discriminatory.
(e) Does not derogate safety or adversely affect the safe and
efficient use of airspace.
(f) To the extent practicable, meets both local needs and needs
of the national air transportation system, considering tradeoffs
between economic benefits derived from the airport and the noise
impact.
(g) Can be implemented in a manner consistent with all of the
powers and duties of the Administrator of FAA.
Sec. B150.7 Analysis of program alternatives.
(a) Noise control alternatives must be considered and presented
according to the following categories:
(1) Noise abatement alternatives for which the airport operator
has adequate implementation authority.
(2) Noise abatement alternatives for which the requisite
implementation authority is vested in a local agency or political
subdivision governing body, or a state agency or political
subdivision governing body.
(3) Noise abatement options for which requisite authority is
vested in the FAA or other Federal agency.
(b) At a minimum, the operator shall analyze and report on the
following alternatives, subject to the constraints that the
strategies are appropriate to the specific airport (for example, an
evaluation of night curfews is not appropriate if there are no
night flights and none are forecast):
(1) Acquisition of land and interests therein, including, but
not limited to air rights, easements, and development rights, to
ensure the use of property for purposes which are compatible with
airport operations.
(2) The construction of barriers and acoustical shielding,
including the soundproofing of public buildings.
(3) The implementation of a preferential runway system.
(4) The use of flight procedures (including the modifications of
flight tracks) to control 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 § 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.
