Pt. 150, App. A
uses around the airport and of pre-
venting the introduction of additional
noncompatible land uses;
(2) The program provides for revision
if made necessary by the revision of
the noise map; and
(3) Those aspects of programs relat-
ing to the use of flight procedures for
noise control can be implemented with-
in the period covered by the program
and without—
(i) Reducing the level of aviation
safety provided;
(ii) Derogating the requisite level of
protection for aircraft, their occupants
and persons and property on the
ground;
(iii) Adversely affecting the efficient
use and management of the Navigable
Airspace and Air Traffic Control Sys-
tems; or
(iv) Adversely affecting any other
powers and responsibilities of the Ad-
ministrator prescribed by law or any
other program, standard, or require-
ment established in accordance with
law.
(c) When a determination is issued,
the Regional Airports Division Man-
ager notifies the airport operator and
publishes a notice of approval or dis-
approval in the F

identifying the nature and extent of
the determination.
(d) Approvals issued under this part
for a program or portion thereof be-
come effective as specified therein and
may be withdrawn when one of the fol-
lowing occurs:
(1) The program or portion thereof is
required to be revised under this part
or under its own terms, and is not so
revised;
(2) If a revision has been submitted
for approval, a determination is issued
on the revised program or portion
thereof, that is inconsistent with the
prior approval.
(3) A term or condition of the pro-
gram, or portion thereof, or its ap-
proval is violated by the responsible
government body.
(4) A flight procedure or other FAA
action upon which the approved pro-
gram or portion thereof is dependent is
subsequently disapproved, significantly
altered, or rescinded by the FAA.
(5) The airport operator requests re-
scission of the approval.
(6) Impacts on flight procedures, air
traffic management, or air commerce
occur which could not be foreseen at
the time of approval.
A determination may be sooner re-
scinded or modified for cause with at
least 30 days written notice to the air-
port operator of the FAA’s intention to
rescind or modify the determination
for the reasons stated in the notice.
The airport operator may, during the
30-day period, submit to the Regional
Airports Division Manager for consid-
eration any reasons and circumstances
why the determination should not be
rescinded or modified on the basis stat-
ed in the notice of intent. Thereafter,
the FAA either rescinds or modifies the
determination consistent with the no-
tice or withdraws the notice of intent
and terminates the action.
(e) Determinations may contain con-
ditions which must be satisfied prior to
implementation of any portion of the
program relating to flight procedures
affecting airport or aircraft operations.
(f) Noise exposure maps for current
and forecast year map conditions that
are submitted and approved with noise
compatibility programs are considered
to be the new FAA accepted noise expo-
sure maps for purposes of part 150.
