Sec. B150.1

Scope and purpose. 

(a) This appendix prescribes the content 

and the methods for developing noise com-
patibility programs authorized under this 
part. Each program must set forth the meas-
ures which the airport operator (or other 
person or agency responsible) has taken, or 
proposes to take, for the reduction of exist-
ing noncompatible land uses and the preven-
tion of the introduction of additional non-
compatible 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 op-
eration of an airport, as well as the costs and 
benefits associated with various alternative 
noise reduction techniques, and the respon-
sible impacted land use control jurisdictions 
can examine existing and forecast areas of 
noncompatibility and consider actions to re-
duce noncompatible uses. 

(2) To bring together through public par-

ticipation, agency coordination, and overall 
cooperation, all interested parties with their 
respective authorities and obligations, there-
by 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 na-
tional air transportation system. 

(3) To develop comprehensive and 

implementable noise reduction techniques 
and land use controls which, to the max-
imum extent feasible, will confine severe air-
craft YDNL values of L

dn

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 be-
tween the L

dn

65 and 75 dB contours. 

Sec. B150.3

Requirement for noise map. 

(a) It is required that a current and com-

plete 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 compat-
ibility program: 

(1) To identify existing and future non-

compatible land uses, based on airport oper-
ation 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 pro-

gram would yield maps differing from those 
previously submitted to FAA, the program 
shall be accompanied by appropriately re-

vised maps. Such revisions must be prepared 
in accordance with the requirements of Sec. 
A150.101(e) of appendix A and will be accept-
ed 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 noncompat-
ible uses; 

(b) Does not impose undue burden on inter-

state 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 con-

sistent 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 con-

sidered and presented according to the fol-
lowing categories: 

(1) Noise abatement alternatives for which 

the airport operator has adequate implemen-
tation authority. 

(2) Noise abatement alternatives for which 

the requisite implementation authority is 
vested in a local agency or political subdivi-
sion governing body, or a state agency or po-
litical subdivision governing body. 

(3) Noise abatement options for which req-

uisite authority is vested in the FAA or 
other Federal agency. 

(b) At a minimum, the operator shall ana-

lyze 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 there-

in, including, but not limited to air rights, 
easements, and development rights, to en-
sure the use of property for purposes which 
are compatible with airport operations. 

(2) The construction of barriers and acous-

tical 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
