SECURITIES AND EXCHANGE COMMISSION

[Release No. 34-73180; File No. SR-NASDAQ-2012-129]

Self-Regulatory Organizations; The NASDAQ Stock Market LLC; Order
Granting an Extension to Limited Exemption From Rule 612(c) of
Regulation NMS in Connection With the Exchange's Retail Price
Improvement Program Until December 31, 2014

September 23, 2014.
    On February 15, 2013, the Commission issued an order pursuant to
its authority under Rule 612(c) of Regulation NMS (``Sub-Penny Rule'')
\1\ that granted the NASDAQ Stock Market LLC (``NASDAQ'') a limited
exemption from the Sub-Penny Rule in connection with the operation of
the Exchange's Retail Price Improvement Program (``Program'').\2\ The
limited exemptions were granted concurrently with the Commission's
approval of the Exchange's proposals to adopt the Program for a one-
year pilot term.\3\ The exemption was granted coterminous with the
effectiveness of the pilot Program; both the pilot Program and the
exemption are scheduled to expire on September 30, 2014.
---------------------------------------------------------------------------

    \1\ 17 CFR 242.612(c).
    \2\ See Securities Exchange Act Release No. 68937 (February 15,
2013), 78 FR 12397 (February 22, 2013) (SR-NASDAQ-2012-129) (``RPI
Approval Order'').
    \3\ See id.
---------------------------------------------------------------------------

    The Exchange now seeks to extend the exemption until December 31,
2014.\4\ The Exchange's request was made in conjunction with an
immediately effective filing that extends the operation of the Program
until December 31, 2014.\5\ In its request to extend the exemption, the
Exchange notes that given the gradual implementation of the Program and
the preliminary participation and results, extending the exemption
would provide additional opportunities for greater participation and
assessment of the results. Accordingly, the Exchange has asked for
additional time to allow it and the Commission to analyze data
concerning the Program, which the Exchange committed to provide to the
Commission.\6\ For this reason and the reasons stated in the RPI
Approval Order originally granting the limited exemption, the
Commission finds that extending the exemption, pursuant to its
authority under Rule 612(c) of Regulation NMS, is appropriate in the
public interest and consistent with the protection of investors.
---------------------------------------------------------------------------

    \4\ See Letter from Jeffrey S. Davis, Vice President & Deputy
General Counsel, NASDAQ to Elizabeth M. Murphy, Secretary,
Commission dated September 11, 2014.
    \5\ See SR-NASDAQ-2014-094.
    \6\ See RPI Approval Order, supra note 2, 78 FR at 12399.
---------------------------------------------------------------------------

    Therefore, it is hereby ordered that, pursuant to Rule 612(c) of
Regulation NMS, the Exchange is granted an extension of the limited
exemption from Rule 612 of Regulation NMS that allows it to accept and
rank orders priced equal to or greater than $1.00 per share in
increments of $0.001, in connection with the operation of its Retail
Price Improvement Program, until December 31, 2014.
    The limited and temporary exemption extended by this Order is
subject to modification or revocation if at any time the Commission
determines that such action is necessary or appropriate in furtherance
of the purposes of the Exchange Act. Responsibility for compliance with
any applicable provisions of the federal securities laws must rest with
the persons relying on the exemption that are the subject of this
Order.

    For the Commission, by the Division of Trading and Markets,
pursuant to delegated authority.\7\

[Docket No. FAA-2016-4221; Directorate Identifier 2015-NM-167-AD]
RIN 2120-AA64

Airworthiness Directives; The Boeing Company Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

-----------------------------------------------------------------------

SUMMARY: We propose to adopt a new airworthiness directive (AD) for all
The Boeing Company Model 767-200 and -300 series airplanes. This
proposed AD was prompted by an evaluation by the design approval holder
(DAH) indicating that the aft pressure bulkhead web to pressure chord
joint is subject to widespread fatigue damage (WFD). This proposed AD
would require repetitive high frequency eddy current (HFEC) inspections
of the aft pressure bulkhead web, at fasteners common to the bulkhead
web and pressure chord, around the entire circumference of the pressure
chord for any crack, and repair of cracks. We are proposing this AD to
detect and correct cracks in the aft pressure bulkhead web. Such
cracking could result in the loss of structural integrity of the
airplane.

DATES: We must receive comments on this proposed AD by April 22, 2016.

ADDRESSES: You may send comments, using the procedures found in 14 CFR
11.43 and 11.45, by any of the following methods:

Discussion

    Structural fatigue damage is progressive. It begins as minute
cracks, and those cracks grow under the action of repeated stresses.
This can happen because of normal operational conditions and design
attributes, or because of isolated situations or incidents such as
material defects, poor fabrication quality, or corrosion pits, dings,
or scratches. Fatigue damage can occur locally, in small areas or
structural design details, or globally. Global fatigue damage is
general degradation of large areas of structure with similar structural
details and stress levels. Multiple-site damage is global damage that
occurs in a large structural element such as a single rivet line of a
lap splice joining two large skin panels. Global damage can also occur
in multiple elements such as adjacent frames or stringers. Multiple-
site-damage and multiple-element-damage cracks are typically too small
initially to be reliably detected with normal inspection methods.
Without intervention, these cracks will grow, and eventually compromise
the structural integrity of the airplane, in a condition known as WFD.
As an airplane ages, WFD will likely occur, and will certainly occur if
the airplane is operated long enough without any intervention.
    The FAA's WFD final rule (75 FR 69746, November 15, 2010) became
effective on January 14, 2011. The WFD rule requires certain actions to
prevent structural failure due to WFD throughout the operational life
of certain existing transport category airplanes and all of these
airplanes that will be certificated in the future. For existing and
future airplanes subject to the WFD rule, the rule requires that DAHs
establish a limit of validity (LOV) of the engineering data that
support the structural maintenance program. Operators affected by the
WFD rule may not fly an airplane beyond its LOV, unless an extended LOV
is approved.
    The WFD rule (75 FR 69746, November 15, 2010) does not require
identifying and developing maintenance actions if the DAHs can show
that such actions are not necessary to prevent WFD before the airplane
reaches the LOV. Many LOVs, however, do depend on accomplishment of
future maintenance actions. As stated in the WFD rule, any maintenance
actions necessary to reach the LOV will be mandated by airworthiness
directives through separate rulemaking actions.
    In the context of WFD, this action is necessary to enable DAHs to
propose LOVs that allow operators the longest operational lives for
their airplanes, and still ensure that WFD will not occur. This
approach allows for an implementation strategy that provides
flexibility to DAHs in determining the timing of service information
development (with FAA approval), while providing operators with
certainty regarding the LOV applicable to their airplanes.
    The FAA has received a report indicating that an evaluation by the
DAH has indicated that the aft pressure bulkhead web to pressure chord
joint is subject to WFD. This condition, if not corrected could result
in cracks from the aft pressure bulkhead web to pressure chord joint
and possible loss of structural integrity of the airplane.

Related Service Information Under 1 CFR part 51

    We reviewed Boeing Alert Service Bulletin 767-53A0268, dated April
1, 2015. This service information describes procedures for repetitive
high frequency eddy current (HFEC) inspections of all visible locations
of the aft pressure bulkhead web, at fasteners common to the bulkhead
web and pressure chord, and around the entire circumference of the
pressure chord for any crack, and repair of cracks. This service
information is reasonably available because the interested parties have
access to it through their normal course of business or by the means
identified in the ADDRESSES section.

FAA's Determination

    We are proposing this AD because we evaluated all the relevant
information and determined the unsafe condition described previously is
likely to exist or develop in other products of the same type design.

Proposed AD Requirements

    This proposed AD would require accomplishing the actions specified
in the service information described previously, except as discussed
under ``Differences Between this Proposed AD and the Service
Information.'' For information on the procedures and compliance times,
see this service information at http://www.regulations.gov by searching
for and locating Docket No. FAA-2016-4221.

Differences between This Proposed AD and the Service Information

    Boeing Alert Service Bulletin 767-53A0268, dated April 1, 2015,
specifies to contact the manufacturer for instructions on how to repair
certain conditions, but this proposed AD would require repairing those
conditions in one of the following ways:
     In accordance with a method that we approve; or
     Using data that meet the certification basis of the
airplane, and that have been approved by the Boeing Commercial
Airplanes Organization Designation Authorization (ODA) whom we have
authorized to make those findings.
    The applicability in this proposed AD is not limited to airplanes
identified in Boeing Alert Service Bulletin 767-53A0268, dated April 1,
2015. That service information does not contain a comprehensive list of
the airplanes that are subject to the identified unsafe condition. This
proposed AD would therefore apply to all Model 767-200 and -300 series
airplanes.

Costs of Compliance

    We estimate that this proposed AD affects 296 airplanes of U.S.
registry.
    We estimate the following costs to comply with this proposed AD:

                                                                     Estimated Costs
--------------------------------------------------------------------------------------------------------------------------------------------------------
                                                                                Cost per
                Action                        Labor cost           Parts cost        product                      Cost on U.S. operators
--------------------------------------------------------------------------------------------------------------------------------------------------------
Inspection...........................  57 work-hours x $85 per              $0           $4,845   $1,434,120 per inspection cycle.
                                        hour = $4,845 per
                                        inspection cycle.
--------------------------------------------------------------------------------------------------------------------------------------------------------

    The size of any repair area needs to be determined before material
and work-hour costs can be calculated. We have received no definitive
data that would enable us to provide cost estimates for the on-
condition actions specified in this proposed AD.

Authority for This Rulemaking

    Title 49 of the United States Code specifies the FAA's authority to
issue rules on aviation safety. Subtitle I, section 106, describes the
authority of the FAA Administrator. Subtitle VII: Aviation Programs,
describes in more detail the scope of the Agency's authority.
    We are issuing this rulemaking under the authority described in
Subtitle VII, Part A, Subpart III, Section 44701: ``General
requirements.'' Under that section, Congress charges the FAA with
promoting safe flight of civil aircraft in air commerce by prescribing
regulations for practices, methods, and procedures the Administrator
finds necessary for safety in air commerce. This regulation is within
the scope of that authority because it addresses an unsafe condition
that is likely to exist or develop on products identified in this
rulemaking action.

Regulatory Findings

    We determined that this proposed AD would not have federalism
implications under Executive Order 13132. This proposed AD would not
have a substantial direct effect on the States, on the relationship
between the national Government and the States, or on the distribution
of power and responsibilities among the various levels of government.
    For the reasons discussed above, I certify this proposed
regulation:
    (1) Is not a ``significant regulatory action'' under Executive
Order 12866,
    (2) Is not a ``significant rule'' under the DOT Regulatory Policies
and Procedures (44 FR 11034, February 26, 1979),
    (3) Will not affect intrastate aviation in Alaska, and
    (4) Will not have a significant economic impact, positive or
negative, on a substantial number of small entities under the criteria
of the Regulatory Flexibility Act.

List of Subjects in 14 CFR Part 39

    Air transportation, Aircraft, Aviation safety, Incorporation by
reference, Safety.

The Proposed Amendment

    Accordingly, under the authority delegated to me by the
Administrator, the FAA proposes to amend 14 CFR part 39 as follows:

PART 39--AIRWORTHINESS DIRECTIVES

0
1. The authority citation for part 39 continues to read as follows:

    Authority:  49 U.S.C. 106(g), 40113, 44701.

Sec.  39.13  [Amended]

0
2. The FAA amends Sec.  39.13 by adding the following new airworthiness
directive (AD):

The Boeing Company: Docket No. FAA-2016-4221; Directorate Identifier
2015-NM-167-AD.

(a) Comments Due Date

    We must receive comments by April 22, 2016.

(b) Affected ADs

    None.

(c) Applicability

    This AD applies to all The Boeing Company Model 767-200 and -300
series airplanes, certificated in any category.

(d) Subject

    Air Transport Association (ATA) of America Code 53, Fuselage.

(e) Unsafe Condition

    This AD was prompted by an evaluation by the design approval
holder (DAH) indicating that the aft pressure bulkhead web to
pressure chord joint is subject to widespread fatigue damage (WFD).
We are issuing this AD to detect and correct cracks in the aft
pressure bulkhead web to pressure chord joint which could result in
the loss of structural integrity of the airplane.

(f) Compliance

    Comply with this AD within the compliance times specified,
unless already done.

(g) Repetitive Inspections

    Except as required by paragraph (h) of this AD, at the
applicable time specified in paragraph 1.E., ``Compliance,'' of
Boeing Alert Service Bulletin 767-53A0268, dated April 1, 2015,
perform a surface high frequency eddy current (HFEC) inspection for
cracking of the aft pressure bulkhead web, at fasteners common to
the bulkhead web and pressure chord, around the entire circumference
of the pressure chord, in accordance with the Accomplishment
Instructions of Boeing Alert Service Bulletin 767-53A0268, dated
April 1, 2015. For this AD, Group 2, Configuration 2, as specified
in Boeing Alert Service Bulletin 767-53A0268, dated April 1, 2015,
includes airplanes with the aft pressure bulkhead replaced as
specified in Boeing Alert Service Bulletin 767-53A0267. Repeat the
inspection thereafter at the applicable time specified in paragraph
1.E., ``Compliance,'' of Boeing Alert Service Bulletin 767-53A0268,
dated April 1, 2015.

(h) Service Information Exception

    Where Boeing Alert Service Bulletin 767-53A0268, dated April 1,
2015, specifies a compliance time ``after the original issue date of
this service bulletin,'' this AD requires compliance within the
specified compliance time after the effective date of this AD.

(i) Crack Repair

    If any crack is found during any inspection required by
paragraph (g) of this AD, before further flight, repair the crack
using a method approved in accordance with the procedures specified
in paragraph (j) of this AD. Although Boeing Alert Service Bulletin
767-53A0268, dated April 1, 2015, specifies to contact Boeing for
repair instructions, and specifies that action as ``RC'' (Required
for Compliance), this AD requires repair as specified in this
paragraph. Installation of a repair terminates the inspections
required by paragraph (g) of this AD in the area covered by the
repair only.

(j) Alternative Methods of Compliance (AMOCs)

    (1) The Manager, Seattle Aircraft Certification Office (ACO),
FAA, has the authority to approve AMOCs for this AD, if requested
using the procedures found in 14 CFR 39.19. In accordance with 14
CFR 39.19, send your request to your principal inspector or local
Flight Standards District Office, as appropriate. If sending
information directly to the manager of the ACO, send it to the
attention of the person identified in paragraph (k)(1) of this AD.
Information may be emailed to<EMAIL_ADDRESS>    (2) Before using any approved AMOC, notify your appropriate
principal inspector, or lacking a principal inspector, the manager
of the local flight standards district office/certificate holding
district office.
    (3) An AMOC that provides an acceptable level of safety may be
used for any repair, modification, or alteration required by this AD
if it is approved by the Boeing

Commercial Airplanes Organization Designation Authorization (ODA)
that has been authorized by the Manager, Seattle ACO to make those
findings. To be approved, the repair method, modification deviation,
or alteration deviation must meet the certification basis of the
airplane and the approval must specifically refer to this AD.
    (4) Except as required by paragraph (i) of this AD: For service
information that contains steps that are labeled as RC, the
provisions of paragraphs (j)(4)(i) and (j)(4)(ii) apply.
    (i) The steps labeled as RC, including substeps under an RC step
and any figures identified in an RC step, must be done to comply
with the AD. An AMOC is required for any deviations to RC steps,
including substeps and identified figures.
    (ii) Steps not labeled as RC may be deviated from using accepted
methods in accordance with the operator's maintenance or inspection
program without obtaining approval of an AMOC, provided the RC
steps, including substeps and identified figures, can still be done
as specified, and the airplane can be put back in an airworthy
condition.

Environmental Financial Advisory Board

AGENCY: Environmental Protection Agency (EPA).

ACTION: Notice of request for nominations of candidates to the
Environmental Financial Advisory Board.

-----------------------------------------------------------------------

SUMMARY: The U.S. Environmental Protection Agency (EPA) invites
nominations of qualified candidates to be considered for appointment to
the Environmental Financial Advisory Board (EFAB or the Board). The
Board provides advice to the EPA on ways to lower the costs of, and
increase investments in, environmental and public health protection.
Appointments will be made by the Administrator and will be announced in
June 2020.

DATES: Nominations should be submitted in time to arrive no later than
January 6, 2020.

ADDRESSES: Nominations should be sent via email to
<EMAIL_ADDRESS>(preferred) or by mail to U.S. Environmental
Protection Agency, Water Infrastructure and Resiliency Finance Center
(4202M), 1200 Pennsylvania Ave. NW, Washington, DC 20460.

FOR FURTHER INFORMATION CONTACT: Any member of the public who wants
further information concerning the nomination process may contact
Stephanie Sanzone, membership coordinator, via telephone/voice mail
(202) 564-2839, or email at<EMAIL_ADDRESS>General
information concerning the EFAB can be found on the EPA website at
https://www.epa.gov/waterfinancecenter/efab.

SUPPLEMENTARY INFORMATION:
    Background: The EFAB is an EPA advisory committee chartered under
the Federal Advisory Committee Act (FACA), 5 U.S.C. App. 2, to provide
advice and recommendations to the EPA on innovative approaches to
financing environmental programs, projects and activities.
Administrative support for the EFAB is provided by the Water
Infrastructure and Resiliency Finance Center within EPA's Office of
Water. The Board was established in 1989 to provide advice and
recommendations to the EPA on the following issues: Reducing the cost
of financing environmental facilities and discouraging polluting
behavior; creating incentives to increase private investment in the
provision of environmental services and removing or reducing
constraints on private involvement imposed by current regulations;
developing new and innovative environmental financing approaches and
supporting and encouraging the use of cost-effective existing
approaches; identifying approaches specifically targeted to small/
disadvantaged community financing; increasing the capacity of state and
local governments to carry out their respective environmental programs
under current Federal tax laws; analyzing how new technologies can be
brought to market expeditiously; and increasing the total investment in
environmental protection of public and private environmental resources
to help ease the environmental financing challenge facing our nation.
    The Board meets in-person two times each calendar year (two days
per meeting) at different locations within the continental United
States. In addition to the bi-annual meetings, teleconference meetings
may be held during the year to ensure timely completion of the Board's
work. Board members typically contribute approximately 5 to 8 hours per
month to the activities of the Board. Members serve on the Board
without compensation; however, Board members may receive travel and per
diem allowances where appropriate and in accordance with Federal Travel
Regulations.
    Members are appointed to represent the perspective of specific
organizations, associations or groups of persons (Representative
members) or to provide their individual expertise (Special Government
Employee, or SGE, members).
    Candidates invited to serve as SGE members will be asked to submit
the ``Confidential Financial Disclosure Form for Environmental
Protection Agency Special Government Employees'' (EPA Form 3110-48).
This confidential form allows the EPA to

determine whether there is a statutory conflict between that person's
public responsibilities as an SGE member and private interests and
activities, or the appearance of a loss of impartiality as defined by
Federal regulation. The form may be viewed at https://www.epa.gov/waterfinancecenter/efab, but this form should not be submitted as part
of a nomination.
    Experience and Expertise Sought for the EFAB: The Board seeks to
maintain diverse representation across all workforce sectors (local/
state/tribal government, business (industry and finance), and nonprofit
organizations) and geographic regions of the United States. Nominees
should demonstrate experience in environmental finance and/or reducing
the cost of financing environmental protection in various environmental
media (water, land and air). Experience and expertise sought include,
but are not limited to, the following areas: Brownfields; commercial
banking; energy efficiency; environmental and financial resiliency;
infrastructure financing; insurance markets; local utility management
and finance; public-public and public-private partnerships; regulators;
resource conservation; sustainable community partnerships; and water
and wastewater utility financial management.
    EPA values and welcomes diversity. In an effort to obtain
nominations of diverse candidates, EPA encourages nominations of women
and men of all racial and ethnic groups. In addition to this notice,
other sources may be utilized in the solicitation of nominees. The
deadline for receiving nominations is Monday, January 6, 2020.
Appointments will be made by the Administrator of the Environmental
Protection Agency and will be announced in June 2020. Nominee
qualifications will be assessed under the mandates of the FACA, which
requires that committees be balanced in terms of the points of view
represented and the functions to be performed; for the Board, this
balance includes diversity across a broad range of constituencies,
sectors and groups.
    How to Submit Nominations: Any interested person or organization
may nominate qualified persons to be considered for appointment to the
EFAB. Individuals may self-nominate. Nominations should be submitted
via email to<EMAIL_ADDRESS>(preferred) or mailed to the
address above. Nominations should include the following information:
Contact information for the person making the nomination; contact
information for the nominee (if different), including full name and
title, business mailing address, telephone and email address; the
specific areas of experience or expertise of the nominee; the nominee's
curriculum vitae or resume; and a biographical sketch of the nominee
indicating current position and recent service on other national
advisory committees or national professional organizations. A
supporting letter of endorsement is encouraged, but not required.
    Evaluation Criteria: The following criteria will be used to
evaluate nominees: Residence in the continental United States;
professional knowledge of, and experience with, environmental financing
activities; senior level-experience that fills a gap in Board
representation or brings a new and relevant dimension to its
deliberations; demonstrated ability to work in a consensus-building
process with a wide range of representatives from diverse
constituencies; and willingness to serve a two or three-year term as an
active and contributing member, with possible re-appointment to a
second term. Under EPA policy, members of EPA advisory committees may
not be in receipt of (or reap substantial direct benefit from) an EPA
grant; this policy does not apply to state, tribal or local government
agency recipients of EPA grants.

40 CFR Part 52

[EPA-R04-OAR-2010-1036; FRL-9643-2]

Approval and Promulgation of Implementation Plans and
Designations of Areas for Air Quality Planning Purposes; Georgia;
Atlanta; Determination of Attainment by Applicable Attainment Date for
the 1997 8-Hour Ozone Standards

AGENCY: Environmental Protection Agency (EPA).

ACTION: Final rule.

-----------------------------------------------------------------------

SUMMARY: EPA is determining that the Atlanta, Georgia, 1997 8-hour
ozone nonattainment Area (hereafter referred to as ``the Atlanta Area''
or ``the Area'') has attained the 1997 8-hour ozone national ambient
air quality standards (NAAQS) by its applicable attainment date of June
15, 2011. The determination of attainment was made by EPA on June 23,
2011, and was based on quality-assured and certified monitoring data
for the 2008-2010 monitoring period. The Atlanta Area is comprised of
Barrow, Bartow, Carroll, Cherokee, Clayton, Cobb, Coweta, Dekalb,
Douglas, Fayette, Forsyth, Fulton, Gwinnett, Hall, Henry, Newton,
Paulding, Rockdale, Spalding and Walton Counties in Georgia. In this
action EPA is determining that the above-identified Area attained the
1997 8-hour ozone NAAQS by its applicable attainment date. EPA is
finalizing this action because it is consistent with the Clean Air Act
(CAA) and its implementing regulations. Additionally, in this action
EPA is clarifying an inadvertent citation error in the proposed
approval for this action.

DATES: This final rule is effective on April 6, 2012.

ADDRESSES: EPA has established a docket for this action under Docket ID
Number EPA-R04-OAR-2010-1036. All documents in the docket are listed in
the www.regulations.gov Web site. Although listed in the electronic
docket, some information is not publicly available, i.e., confidential

SUPPLEMENTARY INFORMATION:

I. What action is EPA taking?
II. What is the effect of this action?
III. What is EPA's final action?
IV. Statutory and Executive Order Reviews

I. What action is EPA taking?

    Based on EPA's review of the quality-assured and certified
monitoring data for 2008-2010, and in accordance with section 181(b)(2)
of the CAA and EPA's regulations, EPA is determining that the Atlanta
Area attained the 1997 8-hour ozone NAAQS by the applicable attainment
date of June 15, 2011.\1\
---------------------------------------------------------------------------

    \1\ Effective June 15, 2004, EPA designated the Atlanta Area as
a marginal area under the 1997 8-hour ozone NAAQS. Subsequently, EPA
took action to reclassify the Area to moderate for the 1997 8-hour
ozone NAAQS. Moderate areas for the 1997 8-hour ozone NAAQS had an
applicable attainment date of June 15, 2010, unless the area
qualified for an extension. On November 30, 2010, EPA took final
action to extend the applicable attainment date for the Atlanta Area
to June 15, 2011. See 75 FR 73969 for more information.
---------------------------------------------------------------------------

    On June 23, 2011, EPA published a determination of attainment for
the Atlanta Area, which served to suspend the requirements for the
State to submit an attainment demonstration and associated reasonably
available control measures (RACM), reasonable further progress (RFP)
plan, contingency measures, and other planning State Implementation
Plan (SIP) revisions related to attainment of the 1997 8-hour ozone
NAAQS so long as the Area continues to attain the 1997 8-hour ozone
NAAQS. See 76 FR 36873. This final rulemaking also includes useful
background information on the 8-hour ozone NAAQS relevant to the
Atlanta Area. Today's action finalizes EPA's determination that the
Atlanta Area attained the 1997 8-hour ozone NAAQS

by the applicable attainment date of June 15, 2011. Today's action is
simply focused on the date by which the Area had attaining data.
    Other specific requirements of the determination and the rationale
for EPA's action are explained in the notice of proposed rulemaking
(NPR) published on December 15, 2011 (76 FR 77950). The comment period
for this action closed on January 17, 2012. No comments were received
in response to the NPR.
    Also, in the NPR, EPA stated that its obligations to determine if
an area attained the 1997 8-hour NAAQS by its applicable attainment
date were found under CAA section 179(c). See 76 FR at 77951-77952. The
citation to section 179(c) was incorrect. EPA notes that for an area
such as Atlanta, which is designated moderate nonattainment for the
1997 8-hour ozone standard, the proper citation is CAA section
181(b)(2)(A). Thus CAA section 181(b)(2) is the correct citation for
the basis of today's action.

II. What is the effect of this action?

    Today's action is a determination that the Atlanta Area attained
the 1997 8-hour ozone NAAQS by its applicable attainment date of June
15, 2011, consistent with CAA section 181(b)(2). Finalizing this action
does not constitute a redesignation of Atlanta Area to attainment of
the 1997 8-hour ozone NAAQS under section 107(d)(3) of the CAA.
Further, finalizing this action does not involve approving maintenance
plans for the Atlanta Area as required under section 175A of the CAA,
nor would it find that the Atlanta Area has met all other requirements
for redesignation. The designation status of the Atlanta Area remains
nonattainment for the 1997 8-hour ozone NAAQS until such time as EPA
determines that the Area meets the CAA requirements for redesignation
to attainment and takes action to redesignate the Area.

III. What is EPA's final action?

    EPA is determining, based on quality-assured and certified
monitoring data for the 2008-2010 monitoring period, that the Atlanta
Area attained the 1997 8-hour ozone NAAQS by the applicable attainment
date of June 15, 2011. This action is being taken pursuant to section
181(b)(2) of the CAA and is consistent with the CAA and its
implementing regulations.

IV. Statutory and Executive Order Reviews

    This action makes a determination of attainment by the applicable
attainment date, based on air quality, and would not impose additional
requirements beyond those imposed by state law. For that reason, this
action:
     Is not a ``significant regulatory action'' subject to
review by the Office of Management and Budget under Executive Order
12866 (58 FR 51735, October 4, 1993);
     Does not impose an information collection burden under the
provisions of the Paperwork Reduction Act (44 U.S.C. 3501 et seq.);
     Is certified as not having a significant economic impact
on a substantial number of small entities under the Regulatory
Flexibility Act (5 U.S.C. 601 et seq.);
     Does not contain any unfunded mandate or significantly or
uniquely affect small governments, as described in the Unfunded
Mandates Reform Act of 1995 (Pub. L. 104-4);
     Does not have Federalism implications as specified in
Executive Order 13132 (64 FR 43255, August 10, 1999);
     Is not an economically significant regulatory action based
on health or safety risks subject to Executive Order 13045 (62 FR
19885, April 23, 1997);
     Is not a significant regulatory action subject to
Executive Order 13211 (66 FR 28355, May 22, 2001);
     Is not subject to requirements of Section 12(d) of the
National Technology Transfer and Advancement Act of 1995 (15 U.S.C. 272
note) because application of those requirements would be inconsistent
with the CAA; and
     Does not provide EPA with the discretionary authority to
address, as appropriate, disproportionate human health or environmental
effects, using practicable and legally permissible methods, under
Executive Order 12898 (59 FR 7629, February 16, 1994).

In addition, this 1997 8-hour ozone determination of attainment by
applicable attainment date for the Atlanta Area does not have tribal
implications as specified by Executive Order 13175 (65 FR 67249,
November 9, 2000), because the SIP is not approved to apply in Indian
country, and EPA notes that it will not impose substantial direct costs
on tribal governments or preempt tribal law.

    The Congressional Review Act, 5 U.S.C. 801 et seq., as added by the
Small Business Regulatory Enforcement Fairness Act of 1996, generally
provides that before a rule may take effect, the agency promulgating
the rule must submit a rule report, which includes a copy of the rule,
to each House of the Congress and to the Comptroller General of the
United States. EPA will submit a report containing this action and
other required information to the U.S. Senate, the U.S. House of
Representatives, and the Comptroller General of the United States prior
to publication of the rule in the Federal Register. A major rule cannot
take effect until 60 days after it is published in the Federal
Register. This action is not a ``major rule'' as defined by 5 U.S.C.
804(2).
    Under section 307(b)(1) of the CAA, petitions for judicial review
of this action must be filed in the United States Court of Appeals for
the appropriate circuit by May 7, 2012. Filing a petition for
reconsideration by the Administrator of these final rules do not affect
the finality of these actions for the purposes of judicial review nor
does it extend the time within which a petition for judicial review may
be filed, and shall not postpone the effectiveness of such rule or
action. This action may not be challenged later in proceedings to
enforce its requirements. (See section 307(b)(2).)

Sec.  52.577  Determination of attainment.

* * * * *
    (d) Based upon EPA's review of the air quality data for the 3-year
period 2008-2010, EPA determined that the Atlanta, Georgia, 1997 8-hour
ozone nonattainment Area attained the 1997 8-hour ozone NAAQS by the
applicable attainment date of June 15, 2011. Therefore, EPA has met the
requirement pursuant to CAA section 181(b)(2) to determine, based on
the Area's air quality as of the attainment date, whether the Area
attained the standard. EPA also determined that the Atlanta, Georgia,
1997 8-hour ozone nonattainment Area is not subject to the consequences
of

failing to attain pursuant to section 181(b)(2).
