§ 34.3

General requirements.

(a) This part provides for the ap-

proval or acceptance by the Adminis-
trator or the Administrator of the EPA
of testing and sampling methods, ana-
lytical techniques, and related equip-
ment not identical to those specified in
this part. Before either approves or ac-
cepts any such alternate, equivalent,
or otherwise nonidentical procedures
or equipment, the Administrator or the
Administrator of the EPA shall consult
with the other in determining whether
or not the action requires rulemaking
under sections 231 and 232 of the Clean
Air Act, as amended, consistent with
the responsibilities of the Adminis-
trator of the EPA and the Secretary of
Transportation under sections 231 and
232 of the Clean Air Act.

(b) Under section 232 of the Act, the

Secretary of Transportation issues reg-
ulations to ensure compliance with 40
CFR part 87. This authority has been
delegated to the Administrator of the
FAA (49 CFR 1.47).

(c)

U.S. airplanes. This part applies to

civil airplanes that are powered by air-
craft gas turbine engines of the classes
specified herein and that have U.S.
standard airworthiness certificates.

(d)

Foreign airplanes. Pursuant to the

definition of ‘‘aircraft’’ in 40 CFR 87.1,
this regulation applies to civil air-
planes that are powered by aircraft gas
turbine engines of the classes specified
herein and that have foreign airworthi-
ness certificates that are equivalent to
U.S. standard airworthiness certifi-
cates. This regulation applies only to
those foreign civil airplanes that, if
registered in the United States, would
be required by applicable regulations
to have a U.S. standard airworthiness
certificate in order to conduct the op-
erations intended for the airplane. Pur-
suant to 40 CFR 87.3(c), this regulation
does not apply where it would be incon-
sistent with an obligation assumed by
the United States to a foreign country
in a treaty, convention, or agreement.

(e) Reference in this regulation to 40

CFR part 87 refers to title 40 of the
Code of Federal Regulations, chapter
I—Environmental Protection Agency,
part 87, Control of Air Pollution from
Aircraft and Aircraft Engines (40 CFR
part 87).

(f) This part contains regulations to

ensure compliance with certain stand-
ards contained in 40 CFR part 87. If
EPA takes any action, including the
issuance of an exemption or issuance of
a revised or alternate procedure, test
method, or other regulation, the effect
of which is to relax or delay the effec-
tive date of any provision of 40 CFR
part 87 that is made applicable to an
aircraft under this FAR, the Adminis-
trator of FAA will grant a general ad-
ministrative waiver of its more strin-
gent requirements until this FAR is
amended to reflect the more relaxed re-
quirements prescribed by EPA.

(g) Unless otherwise stated, all ter-

minology and abbreviations in this
FAR that are defined in 40 CFR part 87
have the meaning specified in that
part, and all terms in 40 CFR part 87
