modification of the conduct of covered
transactions that may be engaged in
with the respondent.
(3) Notice to respondent required. The
suspending official shall provide
prompt written notice to the respondent
of the final suspension order issued to
the regulated entities with respect to
such respondent.
(4) Content of notice. The notice of a
final suspension order shall include:
(i) A statement of the suspension
determination and supporting grounds,
including a discussion of any relevant
information submitted by the
respondent; and
(ii) A copy of the final suspension
order.
(g) Effective date. A final suspension
order shall take effect on the date
specified in the order, which shall be at
least forty-five (45) calendar days after
the date on which the order is signed by
the suspending official.
(a) Time period for request. A
suspended person may submit a request
to the Director for reconsideration of a
final suspension order at any time after
the expiration of a twelve (12)-month
period from the date the order took
effect, but no such request may be made
within twelve (12) months of a previous
request for reconsideration from such
person.
(b) Content of request. A request for
reconsideration must be submitted in
writing and state the specific grounds
for relief from the final suspension
order, which shall be limited to any new
information that may indicate that
engaging in covered transactions with a
regulated entity would no longer
present a risk of significant financial or
reputational harm or threat to the safe
and sound operation of a regulated
entity.
(c) Decision on request. The Director
may approve a request for
reconsideration if the Director
determines that engaging in covered
transactions with a regulated entity is
no longer likely to result in significant
financial or reputational harm to a
regulated entity or otherwise threaten
the safe and sound operation of a
regulated entity. The Director will
inform the requestor of the decision on
the request for reconsideration in a
timely manner. A decision on a request
for reconsideration shall not constitute
an appealable order.
Appeal to the Director.
(a) Opportunity to appeal. A
respondent may submit an appeal to the
Director within thirty (30) calendar days
after the date a final suspension order
has been signed. If the Director signed
the final suspension order as the
suspension official, the respondent has
no appeal right under this section. The
appeal shall be accompanied by a
written brief specifically identifying the
respondent’s objections to the final
suspension order and the supporting
reasons for such objections.
(b) Decision on appeal. The Director
shall issue a written final decision on an
appeal of a final suspension order based
on the record submitted by the
suspending official, together with any
material submitted with an appeal. The
Director may affirm, vacate or amend
the suspension, or remand to the
suspending official for further
proceedings, in the discretion of the
Director. If the Director does not take
action on an appeal prior to the effective
date of the order, the order shall take
effect as if it had been affirmed by the
Director, on the date specified in the
order.
(c) Final agency action. The written
final decision of the Director on an
appeal of a final suspension order shall
be the final agency action. If the Director
does not take action on an appeal prior
to the effective date of the order, the
order shall be the final agency action.
(d) Exhaustion of administrative
remedies. In order to fulfill the
requirement to exhaust administrative
remedies, a respondent must appeal a
final suspension order to the Director as
provided in this section prior to seeking
judicial review of such order.

SUPPLEMENTARY INFORMATION:
Background
Section 231(a)(2)(A) of the Clean Air
Act (CAA) (42 U.S.C. 7571) directs the
Administrator of the EPA to propose
aircraft emission standards applicable to
the emission of any air pollutant from
classes of aircraft engines which, in the
EPA Administrator’s judgment, causes
or contributes to air pollution that may
reasonably be anticipated to endanger
public health or welfare. These emission
standards have been promulgated by the
EPA in 40 CFR part 87.
Section 232 of the CAA (42 U.S.C.
7572) then directs the FAA to prescribe
regulations to ensure compliance with
the EPA’s standards. The FAA has
promulgated these emission standards
in 14 CFR part 34, and in the engine
marking requirements in part 45.
The EPA initially regulated gaseous
exhaust emissions, smoke and fuel
venting from aircraft in 1973, with
occasional revision. Since the EPA’s
adoption of the initial regulations, the
FAA has taken subsequent action to
ensure that the regulations in 14 CFR
are kept current with the EPA’s
standards.
On July 27, 2011, the EPA proposed
new aircraft engine emission standards
for oxides of nitrogen (NOX),
compliance flexibilities, and other
regulatory requirements for aircraft
turbofan or turbojet engines with rated
thrusts greater than 26.7 kilonewtons
(kN) (76 FR 45012). The EPA also
proposed adopting the gas turbine
VerDate Mar<15>2010
16:30 Oct 22, 2013
Jkt 232001
engine test procedures of the
International Civil Aviation
Organization (ICAO). The final rule
adopting these proposals was published
on June 18, 2012 (77 FR 36342), and was
effective July 18, 2012.
On December 31, 2012, the FAA
published a final rule with a request for
comments (77 FR 76842) adopting the
EPA’s new emissions standards in part
34. Although the EPA’s NPRM
presented an opportunity to comment
on the proposed regulations and the
EPA addressed them in its final rule, the
FAA sought public comment on its final
rule.
The FAA received three comments on
the final rule. Concurrent with the
publication of this technical
amendment, the FAA is publishing a
disposition of comments to address the
comments received. No changes are
being made to the final rule based on
those comments, and the comments did
not affect the corrections adopted here.
3. § 34.23—Exhaust Emission Standards
for Engines Manufactured On and After
July 18, 2012
Discussion of Technical Amendments
In § 34.23(b)(1), the table entitled
‘‘Tier 8 Oxides of Nitrogen Emission
Standards for Subsonic Engines’’ was
published with three errors in the
column labeled ‘‘Rated output rO (kN).’’
The FAA is correcting these errors as
follows:
1. Authority Citation
In the amendatory language of the
final rule, we inadvertently changed the
authority citation for section 34 by
replacing the semicolon after ‘‘42 U.S.C.
4321 et seq., 7572’’ with the letter ‘‘1.’’
No change to the authority citation was
intended. We are correcting this error
and returning the authority citation to
what was in place prior to the final rule.
2. § 34.1—Definitions
In the definition of ‘‘Standard day
conditions,’’ the value for ‘‘specific
humidity’’ is incorrectly listed as ‘‘0.00
kg H2O/kg dry air.’’ The correct value is
‘‘0.00634 kg H2O/kg dry air.’’ This error
has existed in § 34.1 for some time, and
the FAA is unable to determine when
this error was introduced. In contrast,
the EPA’s rule correctly defines the
term.
The FAA can find no evidence that
the existence of this error has caused
any significant adverse impact on
engine manufacturers. These
manufacturers have been using the
EPA’s definition to establish compliance
with the exhaust emission requirements.
However, any inconsistency between
the regulations of the EPA and the FAA
could cause confusion. The FAA
intended to correct this error in the final
rule, but inadvertently left this change
out.
Since this correction is not expected
to impose any additional burden on the
manufacturers subject to these
regulations, the FAA is adopting this
change in this document.

In § 34.23, there are two tables that
were published with errors that create
inconsistencies with similar tables in
the EPA’s rule. In the NPRM, the FAA
stated its intent to adopt the standards
promulgated by the EPA. The FAA is
correcting these errors.
A table in § 34.23(a)(2) entitled ‘‘Tier
6 Oxides of Nitrogen Emission
Standards for Subsonic Engines’’ was
published with two errors in the column
labeled ‘‘Rated output rO (kN).’’ The

promulgated by the EPA. The FAA is correcting these errors.
A table in Sec. 34.23(a)(2) entitled ``Tier 6 Oxides of Nitrogen
