Subpart B—Development of Noise 

Exposure Maps and Noise 
Compatibility Programs 

§ 150.21 Noise exposure maps and re-

lated descriptions. 

(a) Each airport operator may after 

completion of the consultations and 
public procedure specified under para-
graph (b) of this section submit to the 
Regional Airports Division Manager 
five copies of the noise exposure map 
(or revised map) which identifies each 
noncompatible land use in each area 
depicted on the map, as of the date of 
submission, and five copies of a map 
each with accompanying documenta-
tion setting forth— 

(1) The noise exposure based on fore-

cast aircraft operations at the airport 
for a forecast period that is at least 5 

years in the future, beginning after the 
date of submission (based on reason-
able assumptions concerning future 
type and frequency of aircraft oper-
ations, number of nighttime oper-
ations, flight patterns, airport layout 
including any planned airport develop-
ment, planned land use changes, and 
demographic changes in the sur-
rounding areas); and 

(2) The nature and extent, if any, to 

which those forecast operations will af-
fect the compatibility and land uses 
depicted on the map. 

(b) Each map, and related docu-

mentation submitted under this sec-
tion must be developed and prepared in 
accordance with appendix A of this 
part, or an FAA approved equivalent, 
and in consultation with states, and 
public agencies and planning agencies 
whose area, or any portion of whose 
area, of jurisdiction is within the L

dn

65 

dB contour depicted on the map, FAA 
regional officials, and other Federal of-
ficials having local responsibility for 
land uses depicted on the map. This 
consultation must include regular 
aeronautical users of the airport. The 
airport operator shall certify that it 
has afforded interested persons ade-
quate opportunity to submit their 
views, data, and comments concerning 
the correctness and adequacy of the 
draft noise exposure map and descrip-
tions of forecast aircraft operations. 
Each map and revised map must be ac-
companied by documentation describ-
ing the consultation accomplished 
under this paragraph and the opportu-
nities afforded the public to review and 
comment during the development of 
the map. One copy of all written com-
ments received during consultation 
shall also be filed with the Regional 
Airports Division Manager. 

(c) The Regional Airports Division 

Manager acknowledges receipt of noise 
exposure maps and descriptions and in-
dicates whether they are in compliance 
with the applicable requirements. The 
Regional Airports Division Manager 
publishes in the F

EDERAL

R

EGISTER

notice of compliance for each such 
noise exposure map and description, 
identifying the airport involved. Such 
notice includes information as to when

and where the map and related docu-
mentation are available for public in-
spection. 

(d) The airport operator shall, in ac-

cordance with this section, promptly 
prepare and submit a revised noise ex-
posure map. 

(1) If, after submission of a noise ex-

posure map under paragraph (a) of this 
section, any change in the operation of 
the airport would create any ‘‘substan-
tial, new noncompatible use’’ in any 
area depicted on the map beyond that 
which is forecast for a period of at 
least five years after the date of sub-
mission, the airport operator shall, in 
accordance with this section, promptly 
prepare and submit a revised noise ex-
posure map. A change in the operation 
of an airport creates a substantial new 
noncompatible use if that change re-
sults in an increase in the yearly day- 
night average sound level of 1.5 dB or 
greater in either a land area which was 
formerly compatible but is thereby 
made noncompatible under Appendix A 
(Table 1), or in a land area which was 
previously determined to be non-
compatible under that Table and whose 
noncompatibility is now significantly 
increased. 

(2) If, after submission of a noise ex-

posure map under paragraph (a) of this 
section, any change in the operation of 
the airport would significantly reduce 
noise over existing noncompatible uses 
that is not reflected in either the exist-
ing conditions or forecast noise expo-
sure map on file with the FAA, the air-
port operator shall, in accordance with 
this section, promptly prepare and sub-
mit a revised noise exposure map. A 
change in the operation of the airport 
creates a significant reduction in noise 
over existing noncompatible uses if 
that change results in a decrease in the 
yearly day-night average sound level of 
1.5 dB or greater in a land area which 
was formerly noncompatible but is 
thereby made compatible under Appen-
dix A (Table 1). 

(3) Such updating of the map shall in-

clude a reassessment of those areas ex-
cluded under section A150.101(e)(5) of 
Appendix A because of high ambient 
noise levels. 

(4) If the forecast map is based on as-

sumptions involving recommendations 
in a noise compatibility program which 

are subsequently disapproved by the 
FAA, a revised map must be submitted 
if revised assumptions would create a 
substantial, new noncompatible use 
not indicated on the forecast map. Re-
vised noise exposure maps are subject 
to the same requirements and proce-
dures as initial submissions of noise ex-
posure maps under this part. 

(e) Each map, or revised map, and de-

scription of consultation and oppor-
tunity for public comment, submitted 
to the FAA, must be certified as true 
and complete under penalty of 18 
U.S.C. 1001. 

(f)(1) Title 49, section 47506 provides 

that no person who acquires property 
or an interest therein after the date of 
enactment of the Act in an area sur-
rounding an airport with respect to 
which a noise exposure map has been 
submitted under section 47503 of the 
Act shall be entitled to recover dam-
ages with respect to the noise attrib-
utable to such airport if such person 
had actual or constructive knowledge 
of the existence of such noise exposure 
map unless, in addition to any other 
elements for recovery of damages, such 
person can show that— 

No person who acquires property or an inter-
est therein after the date of enactment of 
the Act in an area surrounding an airport 
with respect to which a noise exposure map 
has been submitted under section 103 of the 
Act shall be entitled to recover damages 
with respect to the noise attributable to 
such airport if such person had actual or 
constructive knowledge of the existence of 
such noise exposure map unless, in addition 
to any other elements for recovery of dam-
ages, such person can show that— 

(i) A significant change in the type or fre-

quency of aircraft operations at the airport; 
or 

(ii) A significant change in the airport lay-

out; or 

(iii) A significant change in the flight pat-

terns; or 

(iv) A significant increase in nighttime op-

erations; occurred after the date of the ac-
quisition of such property or interest therein 
and that the damages for which recovery is 
sought have resulted from any such change 
or increase.’’ 

(f)(2) Title 49 section 47506(b) further 

provides: 

That for this purpose, ‘‘constructive knowl-
edge’’ shall be imputed, at a minimum, to

§ 150.23 

any person who acquires property or an in-
terest therein in an area surrounding an air-
port after the date of enactment of the Act 
if— 

(i) Prior to the date of such acquisition, 

notice of the existence of a noise exposure 
map for such area was published at least 
three times in a newspaper of general cir-
culation in the county in which such prop-
erty is located; or 

(ii) A copy of such noise exposure map is 

furnished to such person at the time of such 
acquisition. 

(g) For this purpose, the term 

signifi-

cant 

in paragraph (f) of this section 

means that change or increase in one 
or more of the four factors which re-
sults in a ‘‘substantial new noncompat-
ible use’’ as defined in § 150.21(d), affect-
ing the property in issue. Responsi-
bility for applying or interpreting this 
provision with respect to specific prop-
erties rests with local government.

§ 150.23 Noise compatibility programs. 

(a) Any airport operator who has sub-

mitted an acceptable noise exposure 
map under § 150.21 may, after FAA no-
tice of acceptability and other con-
sultation and public procedure speci-
fied under paragraphs (b) and (c) of this 
section, as applicable, submit to the 
Regional Airports Division Manager 
five copies of a noise compatibility pro-
gram. 

(b) An airport operator may submit 

the noise compatibility program at the 
same time as the noise exposure map. 
In this case, the Regional Airports Di-
vision Manager will not begin the stat-
utory 180-day review period (for the 
program) until after FAA reviews the 
noise exposure map and finds that it 
and its supporting documentation are 
in compliance with the applicable re-
quirements. 

(c) Each noise compatibility program 

must be developed and prepared in ac-
cordance with appendix B of this part, 
or an FAA approved equivalent, and in 
consultation with FAA regional offi-
cials, the officials of the state and of 
any public agencies and planning agen-
cies whose area, or any portion or 
whose area, of jurisdiction within the 
L

dn

65 dB noise contours is depicted on 

the noise exposure map, and other Fed-
eral officials having local responsi-
bility of land uses depicted on the map. 
Consultation with FAA regional offi-
cials shall include, to the extent prac-
ticable, informal agreement from FAA 
on proposed new or modified flight pro-
cedures. For air carrier airports, con-
sultation must include any air carriers 
and, to the extent practicable, other 
aircraft operators using the airport. 
For other airports, consultation must 
include, to the extent practicable, air-
craft operators using the airport. 

(d) Prior to and during the develop-

ment of a program, and prior to sub-
mission of the resulting draft program 
to the FAA, the airport operator shall 
afford adequate opportunity for the ac-
tive and direct participation of the 
States, public agencies and planning 
agencies in the areas surrounding the 
airport, aeronautical users of the air-
port, the airport operator, and the gen-
eral public to submit their views, data, 
and comments on the formulation and 
adequacy of that program. Prior to 
submitting the program to the FAA, 
the airport operator shall also provide 
notice and the opportunity for a public 
hearing. 

(e) Each noise compatibility program 

submitted to the FAA must consist of 
at least the following: 

(1) A copy of the noise exposure map 

and its supporting documentation as 
found in compliance with the applica-
ble requirements by the FAA, per 
§ 150.21(c). 

(2) A description and analysis of the 

alternative measures considered by the 
airport operator in developing the pro-
gram, together with a discussion of 
why each rejected measure was not in-
cluded in the program. 

(3) Program measures proposed to re-

duce or eliminate present and future 
noncompatible land uses and a descrip-
tion of the relative contribution of 
each of the proposed measures to the 
overall effectiveness of the program. 

(4) A description of public participa-

tion and the consultation with officials 
of public agencies and planning agen-
cies in areas surrounding the airport, 
FAA regional officials and other Fed-
eral officials having local responsi-
bility for land uses depicted on the
