AGENCY: U.S. Environmental Protection Agency.

ACTION: Final rule.

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

SUMMARY: The Environmental Protection Agency (EPA) is approving the
portions of a State implementation plan (SIP) revision submitted by the
State of California on February 13, 2013 that relate to attainment of
the 1-hour and 1997 8-hour ozone national ambient air quality standards
in the Los Angeles-South Coast area. Specifically, the EPA is approving
the portions of the South Coast Air Quality Management District's Final
2012 Air Quality Management Plan that update the approved control
strategy for the 1997 8-hour ozone standard and that provide a
demonstration of attainment of the 1-hour ozone standard by December
31, 2022. In approving this SIP revision, the EPA finds that an
attainment date of December 31, 2022 is appropriate in light of the
severity of the 1-hour ozone problem in the Los Angeles-South Coast
area and the limited emissions remaining that can be regulated given
the extent to which emissions sources in the South Coast have already
been controlled. As part of this action, the EPA is approving new
commitments adopted by the South Coast Air Quality Management District
to develop, adopt, submit and implement certain near-term measures to
achieve certain aggregate emission reduction targets, updated new
technology provisions, and a new commitment by the California Air
Resources Board to submit contingency measures in 2019 as necessary to
meet the emission reduction targets for 2022 from implementation of new
technology measures.

DATES: This rule is effective on October 3, 2014.

I. Background

    On February 13, 2013, the California Air Resources Board (CARB)
submitted the Final 2012 Air Quality Management Plan (``2012 AQMP'') to
EPA as a revision to the Los Angeles-South Coast Air Basin (``South
Coast'') portion of the California State Implementation Plan
(SIP).1 2 The South Coast Air Quality Management District
(SCAQMD or District) and CARB prepared the 2012 AQMP in response to
EPA's ``SIP call'' under section 110(k)(5) of the Clean Air Act (CAA or
``Act'') for a new attainment demonstration for the 1-hour ozone
standard for South Coast and to meet other CAA requirements.\3\
---------------------------------------------------------------------------

    \1\ Under California law, CARB is the state agency that is
responsible for submitting SIPs and SIP revisions to EPA. CARB is
also responsible for the regulation of mobile sources in California.
Regional air quality management districts, such as the South Coast
Air Quality Management District (SCAQMD or ``District''), are
responsible for developing and adopting regional air quality plans
and for regulating stationary sources. Once adopted, the plans
developed by the regional air quality management districts are
submitted to CARB for adoption as part of the California SIP and
then submitted to EPA for approval or disapproval under section 110
of the CAA.
    \2\ The South Coast includes Orange County, the southwestern
two-thirds of Los Angeles County, southwestern San Bernardino
County, and western Riverside County (see 40 CFR 81.305).
    \3\ Ground-level ozone is an oxidant that is formed from
photochemical reactions in the atmosphere between volatile organic
compounds (VOC) and oxides of nitrogen (NOX)
(collectively referred to as the ozone precursors). The one-hour
ozone national ambient air quality standard (NAAQS or ``standard'')
is 0.12 parts per million (ppm). While the 1-hour ozone standard was
revoked in 2005, certain SIP requirements, such as having an
attainment demonstration, continue to apply in areas, such as the
South Coast, that were designated as nonattainment for the 1997 8-
hour ozone standards under EPA's ``anti-backsliding'' regulations
governing the transition from the 1-hour ozone to the 1997 8-hour
ozone standards. See 40 CFR 51.905.
---------------------------------------------------------------------------

    In addition to the 2012 AQMP, CARB's February 13, 2013 SIP revision
submittal includes the relevant CARB and SCAQMD board resolutions and
other supporting material. The 2012 AQMP updates the approved 1997 8-
hour ozone control strategy,\4\ includes attainment demonstrations for
the 1-hour ozone standard and the 2006 PM2.5 standard, and
includes demonstrations intended to address the vehicle-miles-traveled
emissions offset requirements of CAA section 182(d)(1)(A) for the 1-
hour ozone and 1997 8-hour ozone standards. With respect to the 1997 8-
hour ozone standard, in adopting the 2012 AQMP, the SCAQMD indicated
that, while the 2012 AQMP updates the approved 1997 8-hour ozone
control strategy with new measures designed to reduce reliance on CAA
section 182(e)(5) long-term (i.e., advanced technologies) measures for
VOC and NOX reductions, it is not intended as an update to
other elements of the approved 8-hour ozone control plan.\5\ The 2012
AQMP contains a number of SIP elements for a number of pollutants, but
we are taking action today only on the portions of the 2012 AQMP that
update the approved 1997 8-hour ozone control strategy from the 2007
AQMP and that provide an attainment demonstration for the 1-hour ozone
standard. Specifically, the relevant elements of the 2012 AQMP covered
by our action include:
---------------------------------------------------------------------------

    \4\ In 1997, EPA established an 8-hour ozone NAAQS of 0.08 ppm
(``1997 8-hour ozone standard'') to replace the existing 1-hour
ozone standard. SCAQMD and CARB prepared the 2007 AQMP and 2007
State Strategy (``2007 AQMP''), in part, to demonstrate attainment
of the 1997 8-hour ozone standard and the ozone control strategy
sets for the measures and provisions that the agencies intend to
fulfill to meet the standard by the applicable attainment date. EPA
approved the 2007 AQMP at 77 FR 12674 (March 1, 2012).
    \5\ See SCAQMD Governing Board Resolution No. 12-19 (December 7,
2012).
---------------------------------------------------------------------------

     CARB's resolution of adoption (Resolution 13-3);
     SCAQMD's resolution of adoption (Resolution 12-19);
     The ozone-related portions of chapter 4 of the 2012 AQMP
(``Control Strategy and Implementation'');
     Appendices IV-A (``District's Stationary Source Control
Measures''),

IV-B (``Proposed Section 182(e)(5) Implementation Measures''), and IV-C
(``Regional Transportation Strategy and Control Measures''); and
     Appendix VII (``South Coast 2012 1-hour ozone attainment
demonstration''), which includes 4 attachments, one of which includes a
demonstration of reasonably available control measures (RACM).
    In addition, EPA requested clarification of the commitments made by
SCAQMD and CARB in connection with the 1-hour ozone attainment
demonstration in the 2012 AQMP, and the two agencies responded with the
following letters clarifying their respective commitments:
     Letter from Barry R. Wallerstein, D.Env, SCAQMD Executive
Officer, to Jared Blumenfeld, Regional Administrator, EPA Region IX,
May 1, 2014 (``Wallerstein Letter''); and
     Letter from Richard W. Corey, Executive Officer, CARB, to
Jared Blumenfeld, Regional Administrator, EPA Region IX, May 2, 2014
(``Corey Letter'').
    For simplicity, in referring to the elements on which we are
acting, we are using the term ``2012 AQMP'' even though we recognize
that the 2012 AQMP includes other elements in addition to those covered
in this final action.
    On May 23, 2014 (79 FR 29712), the EPA proposed approval of the
updated control strategy for the 1997 8-hour ozone standard and the 1-
hour ozone attainment demonstration, including the related emissions
inventories, control strategy, and photochemical modeling. In proposing
approval of the 2012 AQMP, we agreed with the State that an attainment
date of December 31, 2022 for the 1-hour ozone standard in the South
Coast is appropriate in light of the severity of nonattainment and the
extent to which emissions sources have already been controlled in the
South Coast. References herein to ``the proposed rule'' or ``our
proposed rule'' refer to our proposal published on May 23, 2014.
    In connection with future baseline emissions in the South Coast as
presented in the 2012 AQMP, we noted in our proposed rule that the
baseline reflects regulations adopted by SCAQMD as of June 2012 and
regulations adopted by CARB by August 2011.\6\ As we noted in our
proposed rule, as a general matter, EPA will approve a State plan that
takes emissions reduction credit for a control measure only where EPA
has approved the measure as part of the SIP, or in the case of certain
on-road and nonroad (or ``off-road'') measures, where EPA has issued
the related waiver of preemption or authorization under CAA section
209(b) or section 209(e). We also noted that, with certain exceptions,
the relevant SCAQMD and CARB rules had been approved into the SIP, and
with respect to the exceptions (recent amendments to SCAQMD Rules 1146,
1146.1, and 1147 and CARB's Consumer Products Regulation), we
anticipated taking final action prior to taking final action on the
revised 1-hour ozone attainment demonstration.\7\ As anticipated, EPA
has taken action on CARB's amended Consumer Product Rule and SCAQMD's
amended Rules 1146 and 1146.1.\8\ As such, the future baseline in the
2012 AQMP reflects, CARB and SCAQMD rules for which EPA has issued
approvals, waivers, or authorizations and that are therefore
enforceable for the purposes of the CAA.
---------------------------------------------------------------------------

    \6\ See 2012 AQMP, appendix III, page III-1-1.
    \7\ With respect to SCAQMD Rule 1147, we determined that the
future baseline emissions in the 2012 AQMP reflect emissions
reductions associated with the version of the rule approved by EPA
at 75 FR 46845 (August 4, 2010) rather than the 2011 amended
version, and thus, approval of the revised South Coast 1-hour ozone
attainment demonstration in the 2012 AQMP does not depend upon EPA
approval of the more recent amendments to that rule.
    \8\ The EPA Region IX Regional Administrator signed direct final
and proposed rules for the amended Consumer Product Rule, and the
amended Rules 1146 and 1146.1, on August 5, 2014 and July 25, 2014,
respectively.
---------------------------------------------------------------------------

    The control strategy for the 1-hour ozone standard includes adopted
measures (i.e., baseline measures that are reflected in the future
baseline emissions inventories), committal measures, and new technology
measures.\9\ The overall control strategy and emissions reductions from
the various components are presented in table 4 of our proposed rule,
which we reprint here for ease of reference.
---------------------------------------------------------------------------

    \9\ ``New technology'' measures is the terms used herein to
refer to the provisions of the 2012 AQMP that update the
corresponding provisions in the 2007 AQMP that anticipate
development of new control techniques or improvement of existing
control technologies. See section 182(e)(5) of the Act.

\a\ The modeling runs that were used to demonstrate attainment of the 1-
  hour ozone standard in the 2012 AQMP were based on the base year
  (2008) summer planning inventories (see table 1 from our proposed
  rule) with adjustments made for weekly and daily temperature
  variations. See 2012 AQMP, appendix VII, page VII-51.

    With respect to the ozone control strategy, we proposed that the
2012 AQMP provides for implementation of all RACM and that the
committal measures and new technology measures relied upon to achieve
necessary emissions reductions were approvable. Specifically, we
proposed to approve the new commitments by the SCAQMD to develop,
adopt, submit and implement 15 new measures as expeditiously as
possible to achieve, in the aggregate, emissions reductions of 6 tons
per day (tpd) of VOC and 11 tpd of NOX by January 1, 2022,
and to substitute any other measures as necessary to make up any
emission reduction shortfall.\10\ The 15 new SCAQMD measures are
summarized in table 5 of our proposed rule, which we reprint here for
ease of reference. For a

detailed description of the measures to which the SCAQMD has committed,
please see appendix VI-A of the 2012 AQMP.
---------------------------------------------------------------------------

    \10\ In our proposed rule, we erroneously described the SCAQMD's
aggregate emissions reductions commitment as 5.8 tpd of VOC and 10.7
tpd of NOX. However, as corrected, the commitment is for
6 tpd of VOC and 11 tpd of NOX. See pages 7 and 8 of
SCAQMD Resolution No. 12-19, table 4-11 of the 2012 AQMP, and the
Wallerstein Letter.

    We noted in our proposed rule that CARB did not make a new
aggregate emissions reduction commitment for the purposes of
demonstrating attainment of the 1-hour ozone standard by December 31,
2022 in the South Coast, but instead relies on the EPA-approved
aggregate emissions reduction commitment under the 2007 AQMP, which
will provide 7 tpd of VOC and 24 tpd of NOX reductions by
January 1, 2022. Considered together, the SCAQMD's new aggregate
emissions reductions commitment and CARB's existing aggregate emissions
reductions commitment under the 2007 AQMP amount to 13 tpd of VOC and
35 tpd of NOX for the purposes of 1-hour attainment in the
South Coast by December 31, 2022.
    We also proposed to approve, as authorized under section 182(e)(5)
of the CAA, provisions that anticipate development of new control
techniques or improvement of existing control technologies. The 2012
AQMP relies on such provisions to achieve emissions reductions of 17
tpd of VOC and 150 tpd of NOX by January 1, 2022 for 1-hour
ozone attainment demonstration purposes. Consistent with the
requirements for CAA section 182(e)(5), we proposed to approve a
related commitment by CARB to develop, adopt, and submit contingency
measures by January 1, 2019 to be implemented if the anticipated
technologies do not achieve the planned reductions.\11\ The 2012 AQMP
frames the section 182(e)(5) provisions in terms of specific measures
referred to herein as ``new technology measures.'' These measures are
summarized in table 6 of our proposed rule, which we reprint here for
ease of reference. See 2012 AQMP, appendix IV-B for a detailed
description of the measures.
---------------------------------------------------------------------------

    \11\ We interpret CARB's contingency measure commitment to be
for January 1, 2019 based on the requirement in section 182(e)(5)
that such measures must be submitted ``no later than 3 years before
proposed implementation of the [advanced control technologies
measures].''

                                                          (e.g., $2,500 for full zero-emission vehicles) for

                                                          This measure continues these programs through 2023.
ONRD-05...............  Further Emission Reductions      This measure calls for CARB to adopt a regulation or
                         from Heavy-Duty Vehicles         other enforceable mechanism to further reduce

                                                          regulation or other enforcement mechanism would
                                                          require, by 2020, all containers transported between
                                                          the marine ports and the near-dock railyards to use
                                                          zero-emission technologies.
OFFRD-01..............  Extension of the SOON Provision  This measure seeks to reduce emissions from older, high-
                         for Construction/Industrial      emitting off-road diesel engines. Under this measure,

    A more detailed discussion of the ozone NAAQS, ozone SIP plans for
the South Coast, EPA's SIP call for a new 1-hour ozone attainment
demonstration as well as the 2012 AQMP and our evaluation of how it
meets the requirements of the CAA can be found in our proposed rule.
The EPA is approving the 2012 AQMP based on our determination that it
complies with applicable CAA requirements and provides for expeditious
attainment of the 1-hour ozone standard in the South Coast.

II. Public Comments and the EPA's Responses

    Our proposed rule provided a 30-day comment period. During this
period, we received a comment letter from Earthjustice on behalf of a
number of community and environmental groups, including Communities for
a Better Environment, Natural Resources Defense Council, Physicians for
Social Responsibility--Los Angeles, and Sierra Club (herein, referred
to collectively as ``Earthjustice''); and a number of emails and
attachments from a member of the public representing the Public Solar
Power Coalition (``PSPC'' herein). The attachments from PSPC included a
copy of the clerk's transcript of case documents from the Superior
Court, Los Angeles County, to the Second District Court of Appeal upon
appeal of Eder v. South Coast Air Quality Management District (SC
119641).\12\ We provide our responses to the comments in the paragraphs
below. We have organized the comments and responses under the related
major topics.
---------------------------------------------------------------------------

    \12\ In its emails to EPA, PSPC did not specify how the 500+
pages of clerk's transcript, included as attachments to their
emails, are relevant to our May 23, 2014 proposed rule. PSPC's
emails also include links to several Web sites and the emails
indicate that the documents and studies available through these web
links are to be included in the record. Again, however, PSPC did not
specify how these materials relate to our proposed rule. Therefore,
other than acknowledging receipt of the attachments and web links,
EPA has no further response to them.
---------------------------------------------------------------------------

One-Hour Ozone Attainment Date

    Comment 1: Earthjustice asserts that EPA erred in relying on CAA
sections 110(k)(5) and 172(a)(2) to set the South Coast's attainment
deadline for the 1-hour standard and was required instead to use
section 179(d)(3). Earthjustice further asserts that, if EPA had acted
correctly, the attainment date would be no later than 2021 rather than
2022.
    Response 1: This comment is not timely and is not relevant to the
current rulemaking. The EPA established the new attainment date for the
1-hour ozone standard in the South Coast in our final SIP call rule,
which was issued on January 7, 2013. See 78 FR 889 (``The SIP must
provide for attainment of the 1-hour ozone NAAQS in the South Coast
nonattainment area as expeditiously as practicable, but no later than
five years from the effective date of today's rule, unless the State
can demonstrate that it needs up to an additional five years to attain
in light of the severity of the nonattainment problem and the
availability and feasibility of control measures.'')
    The 2012 AQMP provides a demonstration of attainment by December
31, 2022 and our proposed rule finds that an attainment date of
December 31, 2022 is appropriate in light of the severity of the 1-hour
ozone problem in the South Coast and the extent to which emission
sources in the South Coast have already been controlled. See 79 FR
29712, at 29724 (May 23, 2014).

CAA Section 182(e)(5)

    Comment 2: Earthjustice asserts that the plain language of the CAA
does not allow for reliance on section 182(e)(5) after the attainment
date. The Act requires states that plan to rely on CAA section
182(e)(5) measures to implement contingency measures ``adequate to
produce emissions reductions sufficient, in conjunction with other
approved plan provisions, to achieve . . . attainment by the applicable
dates'' and that the applicable attainment date for ``extreme'' areas
is November 15, 2010 pursuant to section 181(a)(1). With respect to the
South Coast, Earthjustice argues that the contingency measures are de
facto insufficient to achieve attainment by the applicable dates
because the attainment date of November 15, 2010 has expired, and
because it has expired, it is no longer possible to satisfy the
requirements of section 182(e)(5). Thus, Earthjustice concludes that
the 1-hour ozone attainment demonstration in the 2012 AQMP cannot rely
on section 182(e)(5) measures.
    Response 2: We disagree with the contention that the plain language
of the CAA does not allow for reliance on section 182(e)(5) when a
state fails to meet its initial attainment date and a new attainment
date must be established. Section 182(e) expressly provides EPA with
the authority to approve an attainment demonstration for ``extreme''
ozone areas that anticipates ``development of new control techniques or
improvement of existing control technologies,'' referred to herein as
``new technology'' measures, if certain conditions are met. Nothing in
this provision limits its application only to the initial designations
and classification that occurred immediately following enactment of the
CAA Amendments of 1990. The commenter does not explain why it is ``no
longer possible'' to meet the conditions of section 182(e)(5), and we
explain in the proposed rule why the State has met those requirements.
See 79 FR at 29722-29724 (May 23, 2014).
    Comment 3: Earthjustice argues that an area that fails to attain by
its applicable attainment date should not be allowed to include CAA
section 182(e)(5) measures because it gives states no incentive to
close the ``black box'' within the attainment time frames of the Act.
Earthjustice believes that allowing areas to rely on section 182(e)(5)
provisions after the attainment time frames of the Act creates an
incentive to continually roll ``black'' box reductions past the
attainment date.
    Response 3: We disagree that approving a revised 1-hour ozone
attainment demonstration that relies on new technology measures under
CAA section 182(e)(5) (and referred to as the ``black box'' by
Earthjustice) removes the incentive for states to follow through on the
related emissions reductions within the timeframes of the Act. First,
if the new technology measures in the 2012 AQMP do not achieve the
emissions reductions upon which the 1-hour ozone attainment
demonstration relies (i.e., 17 tpd of VOC and 150 tpd

of NOX), then CARB must submit contingency measures to make
up for the shortfall. CARB has made a commitment to develop and submit
such contingency measures by January 1, 2019.
    Given the extent to which emissions sources in the South Coast are
already controlled, development of section 182(e)(5) contingency
measures will present a significant regulatory challenge to CARB that
can only be avoided or reduced if the new technology measures achieve a
significant portion, if not all, of the emissions reductions expected
from them in the 2012 AQMP. Further, upon the effective date of today's
action, the commitment submitted by CARB to submit such contingency
measures will be part of the California SIP and thus enforceable by EPA
or private citizens.
    Comment 4: Earthjustice asserts that allowing the 1-hour ozone
attainment demonstration in the 2012 AQMP to rely on section 182(e)(5)
measures conflicts with the purpose of section 182(e)(5) because
section 182(e)(5)(A) specifically precludes reliance on new technology
measures to comply with emissions reductions necessary in the first ten
years after enactment of the 1990 Amendments to the Act and thereby
indicates Congress's intention that a 10-year period is too short to
allow reliance on ``black box'' measures to comply with CAA
requirements; because, as a practical matter, the shortened planning
horizon for attainment in the 2012 AQMP does not provide the time
necessary to develop and implement new technology measures; and because
section 182(e)(5)(B) requires contingency measures to be submitted at
least three years in advance of implementation of the measures if the
anticipated technologies do not achieve the anticipated emissions
reductions.
    Earthjustice contends that emissions reductions must be in place by
January 1, 2020 to provide the three years of clean data prior to an
attainment date of December 31, 2022, which means that the contingency
measures under CAA section 182(e)(5)(B) must be submitted by January 1,
2017, less than three years from the present. Given the contrast
between the planning horizon for the 1-hour ozone standard in the 2012
AQMP and the longer (20-year) planning horizon for the initial South
Coast AQMP established under the CAA Amendments of 1990, Earthjustice
concludes that section 182(e)(5) measures cannot be relied upon for the
1-hour ozone attainment demonstration in the 2012 AQMP.
    Response 4: First, the language of section 182(e)(5)(A) does not
preclude reliance on new technology provisions in the new 1-hour ozone
attainment demonstration. Section 182(e)(5)(A) is the first condition
necessary to support reliance on new technology provisions, and to meet
this condition, the EPA must find that such provisions ``are not
necessary to achieve the incremental emission reductions required
during the first ten years after November 15, 1990.'' Since the 10-year
attainment period for the area runs from 2013 until January 1, 2022, by
definition the State has met this condition. Given the plain language
of the Act in this regard, there is no ambiguity to resolve and for
which Congressional intent might be taken into consideration.
    Second, with respect to the practical consideration of whether
sufficient time is available to develop new technology measures to
provide emissions reductions by January 1, 2022 to provide for
attainment of the 1-hour ozone standard by December 31, 2022, we note
that the processes used by the relevant air agencies to develop and
implement the new technology measures are not new to the 2012 AQMP, but
represent a continuation of the effort initiated in the wake of
development of the 2007 AQMP for attainment of the 1997 8-hour ozone
NAAQS and that is unfolding over a longer planning period, similar to
that for the 1-hour ozone plan developed pursuant to the CAA Amendments
of 1990. Third, with respect to the timeline for emissions reductions
and submittal of contingency measures under the 2012 AQMP, we note that
the deadline for emissions reductions necessary for attainment of the
1-hour ozone standard by December 31, 2022 is January 1, 2022, not
January 1, 2020 as asserted by Earthjustice. We explain the basis for
this timeframe in our response to comment 13. Given that all
emission reductions necessary for attainment of the standard must be
achieved by January 1, 2022, the contingency measures under CAA section
182(e)(5)(B) are due to EPA no later than January 1, 2019, not January
1, 2017.
    Thus, CARB had about six years from adoption of the 2012 AQMP, and
has about four years remaining from the date of this final action, to
determine whether it will be able to achieve 17 tpd of VOC and 150 tpd
of NOX reductions in the South Coast for 1-hour ozone
attainment demonstration purposes through the new technology measures
or whether it will need to adopt alternative ``contingency'' measures
to cover some or all of the necessary emissions reductions. This
timeframe does not render application of section 182(e)(5) absurd; to
the contrary, we believe that it is both practicable and reasonable.
    Comment 5: Earthjustice asserts that CAA section 179 governs what
happens when a region fails to meet an ozone standard, and that section
179 does not permit the use of section 182(e)(5) measures.
Specifically, Earthjustice notes that section 179(d)(2) states that the
new plan required under section 179 shall comply with sections 110 and
172 of the CAA and makes no reference to allowing for reliance on
section 182(e)(5).
    Response 5: This comment appears to take issue with EPA's previous
final action determining that the South Coast had failed to attain the
1-hour ozone standard by the November 15, 2010 applicable attainment
date. See 76 FR 82133, at 82145 (December 30, 2011). In that action, we
were clear that the basis for our action was CAA sections 301(a) and
181(b)(2) and not section 179(c). Thus the new 1-hour ozone attainment
demonstration is not governed by the requirements under section
179(d)(2). Regardless, we note that while section 179(d)(2) requires
that the new SIP meet the requirements of CAA sections 110 and 172, it
does not speak to nor preclude reliance on section 182(e)(5). We do not
believe, and the commenter does not suggest, how a SIP for an ozone
area classified as extreme would be inconsistent with the requirements
of sections 110 and 172.
    Comment 6: Even if reliance on CAA section 182(e)(5) were allowed,
EPA's approval is arbitrary and capricious, contends Earthjustice,
because EPA has not determined whether the section 182(e)(5) new
technology measures will produce sufficient emission reductions to
allow the South Coast to meet the attainment deadline. Earthjustice
contends that over half of the proposed section 182(e)(5) measures in
the 2012 AQMP have not been evaluated for their potential to reduce
emissions. Additionally, Earthjustice asserts that, to rely on section
182(e)(5) measures to demonstrate attainment, the SIP must contain
enforceable commitments from agencies responsible for developing and
implementing the measures and that it is unclear from EPA's proposed
rule whether such commitments have been made.
    Response 6: We disagree that to approve the new technology
provisions in the 2012 AQMP, we must determine that the identified new
technology measures will in fact achieve the reductions necessary to
attain the standard. Section 182(e)(5) contemplates that States will
rely on measures not yet fully evolved and for that reason it is
difficult to attribute a

specific tonnage reduction to such measures. The new technology
provisions in the 2012 AQMP reflect greater specificity than the
corresponding provisions from the 2007 AQMP, but do not provide
evidence that they will produce sufficient emissions reductions to
allow the South Coast to meet the attainment deadline for the 1-hour
ozone standard. For many of the individual new technology measures,
emissions reductions were not estimated because they depend upon
funding levels, which are uncertain at this time.
    The fact that the specific emissions reduction estimates for the
individual new technology measures in the 2012 AQMP are not available,
however, is immaterial. Section 182(e)(5) requires, as relevant here,
that the State submit ``enforceable commitments to develop and adopt
contingency measures'' to be implemented if the new technologies do not
achieve the planned reductions. In this case, the 2012 AQMP is relying
on 17 tpd of VOC and 150 tpd of NOX reductions from the new
technology provisions for 1-hour ozone attainment demonstration
purposes. Such contingency measures must be ``adequate to produce
emissions reductions sufficient, in conjunction with other approved
plan provisions, to achieve the periodic emission reductions . . . and
attainment by the applicable dates.'' CARB has submitted the necessary
commitment to develop, adopt and submit such contingency measures by
January 1, 2019. See CARB Resolution 13-3 and Corey Letter dated May 2,
2014.
    Although section 182(e)(5) does not require an enforceable
commitment with respect to the new technology measures, we note that
the State has identified the specific agencies that will be responsible
for developing and implementing the controls or techniques anticipated
under the individual new technology measures, and for the 2012 AQMP,
the SCAQMD has identified such agencies for each of the new technology
measures. In addition, as noted in connection with the 2007 AQMP, EPA,
CARB, the SCAQMD and the San Joaquin Valley Unified Air Pollution
Control District (SJVUACPD) have signed a memorandum of agreement
committing the agencies to coordinate efforts to develop and test new
sustainable technologies to accelerate progress in meeting air quality
goals. See 76 FR 57872, at 57882 (September 16, 2011).

RACM

    Comment 7: Earthjustice asserts that EPA's interpretation of RACM
does not comport with the Clean Air Act's mandate for nonattainment
area plans to provide for attainment of the NAAQS as ``expeditiously as
practicable'' but no later than the applicable attainment date.
Earthjustice bases this assertion on what it perceives to be the
inconsistency between the ``expeditiously as practicable'' mandate and
EPA guidance, which provides that, to address the requirement to adopt
all RACM, states should consider all potentially reasonable control
measures in the nonattainment area to determine whether they are
reasonably available for implementation in that area and whether they
would, if implemented individually or collectively, advance the area's
attainment date by one year or more. Earthjustice contends that the
one-year condition is arbitrary and that it allows the states to avoid
implementation of otherwise feasible and cost-effective control
measures if implementation of those measures would not advance
attainment by at least one year. Earthjustice also contends that it is
arbitrary and capricious for EPA to rely on a guidance document that
limits RACM to measures that advance attainment by one year as opposed
to measure that may advance attainment by 9 months, 6 months, 3 months
or even 1 month.
    The one-year condition on the RACM requirement, Earthjustice
asserts, is exacerbated by EPA taking this position for extreme ozone
nonattainment areas that may rely on new technology measures under CAA
section 182(e)(5), as well as areas that have missed their attainment
dates ``because the region has not even identified enough control
measures to attain in the first place.'' Earthjustice claims that the
availability of CAA section 182(e)(5) in extreme areas means that
measures can be rejected arbitrarily as not meeting RACM.
    Lastly, Earthjustice suggests that EPA should instead change its
interpretation of RACM in extreme nonattainment areas that rely on new
technology measures to require a demonstration that all feasible
control measures have been adopted, regardless of whether those control
measures can be demonstrated to advance attainment by a year. It also
requests clarification that RACM represents the minimum level of
control states are required to demonstrate in nonattainment plans and
that other measures are also required, as necessary or appropriate, to
attain the NAAQS as expeditiously as practicable, regardless of whether
the measures are considered RACM.
    Response 7: EPA has consistently interpreted RACM as a collection
of measures that would advance the attainment date by at least one
year, and the courts have determined that the statutory RACM
requirement is ambiguous and deferred to EPA's interpretation of the
requirement. See Sierra Club v. EPA, 314 F.3d 735, 744-745 (5th Cir.
2002); see also Sierra Club v. EPA, 294 F.3d, 155, 162 (D.C. Cir.
2002). See also 57 FR 13498, 13560 (April 16, 1992); 44 FR 20372, 20374
(April 4, 1979).\13\ In considering whether a collection of measures
would advance the attainment date of an area, EPA has previously
interpreted the phrase ``advance the attainment date'' as meaning that
the attainment date would be advanced by at least one year. See e.g.,
66 FR 57160, 57182 (November 14, 2001) (approval of Houston 1-hour
ozone SIP); 66 FR 586 (January 3, 2001) (approval of DC area 1-hour
ozone SIP); 76 FR 57872, 57877 (September 16, 2011)(proposed approval
of South Coast 8-hour ozone SIP--finalized at 77 FR 12674 (March 1,
2012); and 77 FR 12652, 12659-12660 (March 1, 2012)(approval of San
Joaquin Valley 8-hour ozone SIP). EPA's use of a one-year increment in
determining whether a collection of measures would advance the
attainment date is reasonable and consistent with the fact that
determinations of attainment, or failure to attain, the 1-hour ozone
standard are based on data compiled on a calendar-year basis (see 40
CFR 50.9 and appendix H to 40 CFR part 50). Furthermore, sections
172(a)(2)(C) and 181(a)(5) use one year as the increment by which
attainment date extensions can be granted. Thus, requiring evaluation
of whether control measures would advance attainment by an increment of
one year is a reasonable approach.
---------------------------------------------------------------------------

    \13\ Additional relevant EPA guidance includes EPA memorandum
titled ``Guidance on the Reasonably Available Control Measures
(RACM) Requirement and Attainment Demonstration Submissions for
Ozone Nonattainment Areas,'' November 30, 1999, and EPA memorandum
titled ``Additional Submission on RACM from States with Severe One-
Hour Ozone Nonattainment Area SIPs,'' December 14, 2000.
---------------------------------------------------------------------------

    Second, we disagree that the one-year condition for consideration
of RACM in areas that rely on CAA section 182(e)(5) new technology
measures to demonstrate attainment (and thus have not identified the
specific measures needed to attain the standard) allows for arbitrary
rejection of measures as not meeting RACM. So long as attainment plans
developed for such areas identify base year emissions, an attainment
date, and attainment-year emission targets, the emissions reductions
associated with advancement of the attainment

date by one year can be calculated. Such an estimate can be used to
judge whether a collection of reasonably available measures would
advance attainment by one year notwithstanding the reliance on new
technology measures. Thus, EPA's long-standing interpretation of RACM
in terms of a collection of measures that would advance the attainment
date of an area is not arbitrary as applied to areas that rely on
section 182(e)(5) new technology measures.
    In the case of the 1-hour ozone standard and the 2012 AQMP, the
emissions reductions associated with advancement of the attainment date
by one year are roughly 14 tpd of VOC and 46 tpd of NOX
based on 2008 base year emissions and the emissions targets for
attainment by December 31, 2022. As described in appendix VI
(``Reasonably Available Control Measures (RACM) Demonstration'') of the
2012 AQMP, the SCAQMD updated previous RACM demonstrations for purposes
of evaluating all feasible control measure concepts for inclusion in
the 2012 AQMP. Ultimately, SCAQMD adopted 15 new committal measures
(see table 5 of our proposed rule) to ensure implementation of RACM.
The collection of measures that were rejected as RACM were rejected
because the hypothetical reductions were deemed non-quantifiable and
thus they would not collectively advance the attainment date. See pages
VI-18 and VI-19 of appendix VI of the 2012 AQMP.
    Also, we disagree with the contention that EPA's one-year condition
for consideration of RACM is absurd as applied to areas that have
failed to attain the standard ``because the region has not even
identified enough control measures to attain in the first place.'' RACM
demonstrations and the attainment demonstrations upon which they rely
are prepared, submitted and approved years before the applicable
attainment date and are based on the best information available at the
time. Notwithstanding approval of well-conceived and well-grounded RACM
and attainment demonstrations that meet all CAA requirements, the area
to which the demonstrations apply may still fail to attain the standard
by the applicable attainment date for any number of reasons, such as
assumptions regarding atmospheric chemistry or population forecasts
that ultimately prove to be inaccurate when viewed in retrospect. Thus,
the failure of an area to attain the standard by the applicable
attainment date sheds no light on the appropriateness of the state's
RACM demonstration or EPA approval of it years before but sets the
stage for a new attainment date, and the type of RACM reevaluation and
new attainment demonstration that is included in the 2012 AQMP.
    Lastly, the EPA confirms that implementation of RACM as
expeditiously as practicable represents the minimum level of control
states are required to demonstrate in nonattainment plans. See CAA
section 172(c)(1). We clarify that, in such plans, other measures are
also required, as may be necessary or appropriate, to provide for
attainment of the NAAQS ``by the applicable attainment date specified
in this part.'' See CAA section 172(c)(6).
    Comment 8: Even if EPA's interpretation of RACM is adequate, SCAQMD
did not perform a proper RACM analysis because SCAQMD did not evaluate
Indirect Source Rule Fees for RACM, which was a RACM commitment in the
San Joaquin Valley.
    Response 8: We disagree with the contention that SCAQMD's RACM
demonstration for the 2012 AQMP was insufficient because it did not
evaluate Indirect Source Rule (ISR) Fees. We recognize that the San
Joaquin Valley air district has adopted, and EPA has approved, an ISR
rule, Rule 9510 (``Indirect Source Review''), which includes an off-
site fee element. However, in doing so, the air district and EPA acted
under CAA section 110(a)(5). See 76 FR 26609 (May 9, 2011). Under that
section of the CAA, EPA is prohibited from requiring states to include
ISR programs in SIPs. Specifically, CAA section 110(a)(5)(A)(i) states
in relevant part: ``Any State may include in a State implementation
plan, but the Administrator may not require as a condition of approval
of such plan under this section, any indirect source review program.
The Administrator may approve and enforce, as part of an applicable
implementation plan, an indirect source review program which the State
chooses to adopt and submit as part of its plan.'' [Emphasis added.] An
ISR Fee rule would constitute an ISR program, and thus, EPA may not
require SCAQMD to consider such a rule as a RACM.
    Comment 9: Earthjustice asserts that SCAQMD must evaluate the
programs that SCAQMD is planning to use as ``qualified'' programs to
fund the Rule 317 section 172(e) fee equivalency account, as RACMs.
Earthjustice claims that, under Rule 317, ``qualified'' programs
represent those that are ``surplus'' to the plan requirements to attain
the 1-hour ozone standard and that reduce emissions from mobile sources
by providing incentive funding that advances the state of mobile source
emission reduction technology, improves fuel and engine infrastructure,
and accelerates fleet turnover. The programs included in Rule 317, the
commenter explains, include School Bus Replacement, Truck Retrofits,
Clean Vehicle Rebate Programs, Hybrid Truck and Bus Voucher Incentives,
Natural Gas Taxi Cabs and Shuttle Vans, a Lawnmower Exchange program,
and others. Earthjustice asserts that SCAQMD must analyze all of the
programs cited in Rule 317 under the RACM analysis to determine whether
the programs will individually or collectively advance the date of
attainment to meet the requirements of section 172(c)(1), and that, if
any of the programs meet the definition of RACM, the programs must be
adopted by SCAQMD in enforceable form in the nonattainment plans to
meet the 1-hour and 8-hour ozone standards in the South Coast.
    Response 9: SCAQMD Rule 317 (``Clean Air Act Non-attainment Fees'')
is intended to satisfy the requirements of sections 182 and 185 of the
Act under EPA's anti-backsliding rules governing the transition from
the revoked 1-hour ozone standard to the 1997 8-hour ozone standard.
The rule utilizes an equivalency approach consistent with the
principles of section 172(e) of the Act. EPA approved Rule 317 as a
revision to the California SIP at 77 FR 74372 (December 14, 2012).
    RACM identifies a certain level of control of existing emissions
sources that must be adopted in legally enforceable form. Incentive
programs by their nature are voluntary, i.e., not enforceable, and thus
are not the types of programs that a State must consider in its RACM
evaluation. Moreover, the types of sources to which the incentive
programs in Rule 317 apply are mobile sources, and as explained in our
proposed rule, 79 FR at 29720 (May 23, 2014), we have found that CARB's
mobile source program continues to meet the RACM requirement for such
sources. CARB's mobile source program includes regulations for many
types of existing (i.e, in-use) vehicles and equipment, including the
types of vehicles and equipment to which the Rule 317 incentive
programs apply.
    Comment 10: The commenter asserts that, because the South Coast
failed to attain the 1-hour ozone NAAQS, the revised 1-hour ozone
attainment plan must include such additional measures as EPA may
reasonably prescribe, including all measures that can be feasibly
implemented in the area in light of technological achievability, costs,
and any non-air quality and other air quality-related health and

environmental impacts to comply with the requirements for such plans
under CAA section 179(d)(2). The commenter states that pursuant to that
provision, EPA should have prescribed potential feasible measures for
achieving the standard, and suggests that the elimination of the
exemption of methane from the definition of ``volatile organic
compounds'' (VOCs) is one such potential measure that should have been
prescribed and evaluated.
    Response 10: In December 2011, we issued a final action determining
pursuant to CAA sections 301(a) and 181(b)(2), that the South Coast had
failed to attain the 1-hour standard by the applicable attainment date.
We did not base that determination on section 179(c), and thus the plan
requirements specified in CAA section 179(d) do not apply. Thus, this
comment is not timely.
    We note that EPA regulations exempt methane from the definition of
VOC, 40 CFR 51.100(s), and the South Coast regulations are consistent
with the EPA regulation. The EPA regulation exempting methane from the
definition of ``VOC'' stems from the Agency's determination that
methane is an organic compound that has negligible photochemical
reactivity and thus need not be controlled for the purposes of reducing
ground-level ozone concentrations. Independent of that, however, we
recognize methane as a potent greenhouse gas and we note that many
control measures that reduce VOC emissions have the co-benefit of
reducing methane. Because EPA regulations exempt methane from the
definition of VOC for the purpose of reduce ground-level ozone
concentrations, it would not be appropriate for the State to rely on
methane reductions as part of its plan to attain the 1-hour ozone
NAAQS.

Enforceable Commitments

    Comment 11: Earthjustice contends that EPA cannot approve
California's reliance on section 172(c)(6) enforceable commitments
because the state's proposed commitments are not enforceable and are
insufficient to substitute for the credible emission reductions needed
to demonstrate attainment. More specifically, Earthjustice notes that
three of CARB's existing commitments in the 2012 AQMP do not have
schedules for implementation, and without such schedules for
implementation, CARB's measures are not ``independently enforceable''
under Ninth Circuit case law, citing El Comite Para El Bienestar de
Earlimart v. Warmerdam, 539 F.3 1062, at 1071-1073 (9th Cir. 2008). The
three CARB measures cited by Earthjustice include expanding passenger
vehicle retirement, promoting cleaner ship engines and fuel, and
adopting off-road recreational vehicle expanded emissions standards. In
addition, Earthjustice contends that the SCAQMD's reservation of the
right to substitute measures for the 15 specific measures adopted by
SCAQMD to meet its emissions reduction commitment renders the measures
unenforceable should the District choose to implement other,
undisclosed measures.
    Response 11: The 1-hour ozone attainment demonstration in the 2012
AQMP relies on existing CARB commitments approved by EPA in connection
with the attainment demonstration for the 1997 8-hour ozone standard in
the 2007 AQMP. More specifically, the 1-hour ozone attainment
demonstration in the 2012 AQMP relies on the same commitments made by
CARB, and approved by EPA, in connection with the 2007 AQMP to take
certain defined measures to its Board for consideration and to achieve
certain aggregate emissions reductions in certain years. In responses
to comments in our final rule approving the commitments for the 8-hour
ozone standard attainment demonstration, we addressed in detail the
issue of enforceability of the commitments. See 77 FR 12674, at 12675-
12677 (March 1, 2012). In short, however, we draw a sharp distinction
between the commitments for the 2007 AQMP and the aspirational goals
found to be unenforceable by certain courts. In contrast to an
unenforceable aspirational goal, we found:

    The language in CARB's and the District's commitments . . . is
specific; the intent of the commitments is clear; and the strategy
of adopting measures to achieve the required reductions is
completely within CARB's and the District's control. Furthermore . .
. CARB and the District identify specific emission reductions that
they will achieve, how they could be achieved and the time by which
these reductions will be achieved, i.e., by the 2023 attainment
year. 77 FR 12674, at 12676-12677 (March 1, 2012).

Although the excerpt from our March 2012 final rule refers to the
commitments for the attainment year for the 1997 8-hour ozone standard,
CARB also made similar types of commitments for certain interim years,
including year 2020, and a similar rationale applies. See 77 FR at
pages 12689-12692 (March 1, 2012).
    As to commitments related to expanding passenger vehicle
retirement, promoting cleaner ship engines and fuel, and adopting off-
road recreational vehicle expanded emissions standards, we disagree
that the CARB has failed to include schedules for implementation and
that, therefore, the commitments are unenforceable. We discuss the
commitments related to these three control strategies and the current
status of implementation in the following paragraphs.
    First, with respect to expanding passenger vehicle retirement,
CARB's 2007 State Strategy calls for expanding the existing vehicle
retirement program to vehicles that are off-cycle from their Smog Check
inspections over an implementation period of 2008-2014.\14\ In 2007,
the California enacted the California Alternative and Renewable Fuel,
Vehicle Technology, Clean Air, and Carbon Reduction Act of 2007
(Assembly Bill (AB) 118), which creates the Air Quality Improvement
Program (AQIP). The Enhanced Fleet Modernization Program (EFMP), one of
the AQIP programs, is a voluntary vehicle retirement program that is
funded through a $1 increase in vehicle registration fees (roughly $30
million annually) and that broadens eligibility criteria beyond vehicle
failure under the Smog Check program. The California Legislature
recently extended the program through 2023 (AB 8). In June 2014, CARB
proposed amendments to the EFMP that would improve the program by
focusing the program on low-income participants, expanding program
flexibility to improve participation, and ensuring that retired
vehicles are functional, which should improve emissions benefits from
the program.
---------------------------------------------------------------------------

    \14\ See CARB's Proposed State Strategy for California's 2007
State Implementation Plan, Release Date: April 26, 2007, pages 100-
101.
---------------------------------------------------------------------------

    Second, as to promoting cleaner ship engines and fuel, CARB
committed to adopting regulations to require use of cleaner, low-sulfur
fuel by ocean-going vessels (OGV) in transit within 24 miles of the
California coast with implementation expected from 2007-2010.\15\ In
2008, CARB adopted the OGV clean fuel (i.e., low sulfur) regulations,
and later amended the regulations in 2011. CARB's OGV clean fuel
regulation is expected to be supplanted in 2015 by equivalent fuel
standards applicable to a much wider area (200 nautical miles) along
the California coast under the 2010 amendments, adopted by the
International Maritime Organization (IMO), to the International
Convention for the Prevention of Pollution from Ships (MARPOL)
designating the North American Emission Control Area (ECA).

MARPOL Tier III NOX standards \16\ will apply within the
North American ECA to marine diesel engines that are installed on a
ship constructed on or after January 1, 2016.
---------------------------------------------------------------------------

    \15\ See CARB's Proposed State Strategy for California's 2007
State Implementation Plan, Release Date: April 26, 2007, pages 107-
110.
    \16\ The current Tier I NOX standards range from 9.8
to 17 g/kW-h, depending on engine speed. The Tier II standards
represent a 20 percent NOX reduction below Tier I, and
the Tier III standards represent an 80 percent NOX
reduction below Tier I.
---------------------------------------------------------------------------

    Third, as to adopting off-road recreational vehicle expanded
emissions standards, CARB committed to bringing the emissions standards
to its Board for consideration in 2013, with implementation schedules
to be determined in the rulemaking process.\17\ In July 2013, CARB
adopted regulations establishing more extensive evaporative emissions
standards for new off-highway recreational vehicles beginning with
model year 2018.
---------------------------------------------------------------------------

    \17\ See CARB's Progress Report on Implementation of
PM2.5 State Implementation Plans (SIP) for the South
Coast and San Joaquin Valley Air Basins, Release Date: March 29,
2011, appendix B (``Rulemaking Calendar'').
---------------------------------------------------------------------------

    As to the enforceability of SCAQMD's commitments in the 2012 AQMP,
Earthjustice is correct that, in committing to develop, adopt,
implement and submit the 15 measures listed in table 5 of the proposed
rule, SCAQMD reserved the right to substitute measures where a listed
measure is found to be infeasible and to otherwise substitute measures
that can achieve equivalent reductions in the same adoption or
implementation timeframes. See 2012 AQMP, pages 4-42 and 4-43. However,
SCAQMD's commitment to the 15 defined measures is supported by the
related, but independently enforceable, commitment to achieve aggregate
emission reductions of 6 tpd of VOC and 11 tpd of NOX by
January 1, 2022. The aggregate emissions reduction commitment
sufficiently ensures that the District will achieve the 6 tpd of VOC
and 11 tpd of NOX that is relied upon by the 1-hour ozone
attainment demonstration, notwithstanding the potential for
substitution of the individual measures by the SCAQMD.
    Moreover, the SCAQMD has committed to be bound by a process with
significant safeguards to ensure the integrity of the regulatory
commitment. For instance, as described in more detail on pages 4-43 and
4-44 of the 2012 AQMP, the SCAQMD has defined ``infeasibility'' for the
purposes of measure substitution, set cost-benefit thresholds
triggering refined analysis, and established a public review and
decision process. With such safeguards, we expect SCAQMD to make few
substitutions, leaving most of the individual measures fully
enforceable as part of the SIP.
    Comment 12: Earthjustice challenges EPA's determination that CARB
and SCAQMD are capable of fulfilling their aggregate emission reduction
commitments, contending that such a determination conflicts with EPA's
earlier finding that there are few opportunities to further reduce
emissions and that six of SCAQMD's defined measures do not have
estimated emission reductions. Without such reduction estimates,
Earthjustice argues, EPA has no reason to believe that California will
satisfy its emission reductions commitments.
    Response 12: EPA's statement as to the few opportunities to further
reduce emissions was made by way of explanation for why we believe
that, with respect to the 2012 AQMP 1-hour ozone attainment
demonstration, circumstances warrant the consideration of enforceable
commitments as part of the attainment demonstration for the South
Coast. We do not find this statement to be in conflict with our stated
belief that CARB and SCAQMD are capable of fulfilling their aggregate
emissions reductions ``given the State's and SCAQMD's efforts to date
to reduce emissions and the proposed stationary and mobile source
strategies found in the 2012 AQMP.'' The former simply acknowledges the
unique challenges facing the air agencies in the South Coast relative
to other parts of the country to identify source categories for
additional controls beyond those already adopted and implemented, while
the latter notes the long-term success of the air agencies in
identifying sources to regulate emission sources to achieve the
necessary reductions notwithstanding the challenges.\18\
---------------------------------------------------------------------------

    \18\ The full statement from our May 23, 2014 proposed rule
regarding the few opportunities to further reduce emissions is: ``As
a result of these State and District efforts, most sources in the
South Coast nonattainment area are currently subject to stringent
rules adopted and approved by EPA (or for which EPA has issued
waivers or authorization in the case of CARB regulations) prior to
the development of the 2012 AQMP, leaving few opportunities (and
generally more technologically and economically challenging ones) to
further reduce emissions.'' 79 FR 29712, at 29721 (May 23, 2014).
---------------------------------------------------------------------------

    Earthjustice is correct that SCAQMD does not provide emissions
reduction estimates for six of the 15 measures that the District has
committed to develop, adopt, submit and implement. However, as further
explained in the proposed rule, 79 FR 29712, at 29721 (May 23, 2014),
SCAQMD is relying on emissions reductions from the SOON program as well
as the emissions reductions from the 15 individual measures to meet its
aggregate emissions reduction commitment. The emissions reductions
estimated from the SOON program plus those from the measures for which
SCAQMD has provided emissions reduction estimates is equal to the
aggregate commitment. See table 5 from the proposed rule and pages IV-
B-30 through IV-B-32 from appendix IV-B of the 2012 AQMP. Thus, we
continue to believe that SCAQMD is capable of fulfilling its aggregate
emission reduction commitment to achieve necessary emissions reductions
by January 1, 2022.
    Comment 13: Earthjustice contends that CARB's and SCAQMD's
emissions reduction commitments are not for a ``reasonable and
appropriate period of time,'' because the agencies anticipate
fulfilling their commitments by January 1, 2022--less than a year
before the 1-hour ozone attainment deadline of December 31, 2022, and
that EPA provides no support for the notion that the agencies will meet
the December 31, 2022 deadline simply by fulfilling their commitments
by January 1, 2022. To the contrary, Earthjustice argues, these
agencies have not demonstrated that the emissions reduction would occur
within a 12-month time frame. In addition, Earthjustice claims that the
agencies could not achieve three years of clean data if the agencies
wait until January 1, 2022 to fulfill commitments.
    Response 13: First, SCAQMD and CARB have committed to achieve
aggregate emissions reductions by January 1, 2022 and are already at
work meeting that commitment, and thus, these agencies have more than
seven years to fulfill the commitments and achieve the reductions
necessary for attainment, not 12 months as suggested by the commenter.
    Second, SCAQMD and CARB commitments to achieve emissions reductions
by January 1, 2022 is consistent with the requirement to ensure that
necessary emissions reductions are in place by the beginning of the
ozone season immediately preceding the attainment deadline. Since the
attainment deadline is December 31, 2022, the ozone season immediately
preceding that deadline begins on January 1, 2022 for the South Coast.
    Reductions necessary to demonstrate attainment by December 31, 2022
need not be in place three years before the deadline. The three-year
record of clean data applies to an attainment determination, not to an
attainment demonstration, the latter of which we are approving today.
The determination of attainment required by CAA section 181(b)(2),
which is made by reviewing

ambient air quality monitoring data after the attainment date, is
distinctly different from the demonstration of attainment required by
CAA section 182(c)(2), which is based on projections of future air
quality levels and submitted before the attainment date.
    For the 1-hour ozone standard, an attainment determination is based
on monitored air quality levels in the three years preceding the
attainment date. See 57 FR 13498, at 13506 (April 16, 1992). In
contrast, an attainment demonstration is based on air quality modeling
showing that projected emissions in the attainment year will be at or
below the level needed to prevent violations of the relevant ambient
air quality standard. For ozone, the attainment year is defined as the
calendar year that includes the last full ozone season prior to the
statutory attainment date. See 75 FR 10420, at 10431 (March 8, 2010)
(Final approval of San Joaquin Valley 1-hour ozone attainment
demonstration; later withdrawn at 77 FR 70376 (November 26, 2012) on
other grounds). EPA has consistently interpreted the Act to require
that the attainment demonstration show that air quality levels will be
at or below the level of the standard in the attainment year and not
for each of the three ozone seasons prior to the attainment date.
    We believe this position is consistent with the ozone attainment
provisions in subpart 2 of title 1, part D of the CAA. The program
Congress crafted for ozone attainment does not require that all
measures needed to attain the standard be implemented three years prior
to the area's attainment date. For example, moderate areas were
required by section 182(b)(1) to provide for VOC emissions reductions
of 15 percent reduction by November 15, 1996 which was also the
attainment date for these areas. For areas classified serious and
above, CAA section 182(c)(2)(B) requires that ROP of 3 percent per year
averaged over 3 years ``until the attainment date'' (a total of 9
percent reduction in emissions in the 3 years leading up to an area's
attainment date). EPA does not believe that Congress intended these
mandatory reductions to be in excess of what is needed to attain.
    This position is also consistent with the attainment date extension
provisions in CAA section 181(a)(5). Under this section, an area that
does not have three years of data meeting the ozone standard by its
attainment date, but has complied with all requirements and commitments
pertaining to the area in the applicable implementation plan and has no
more than one exceedance of the standard in the attainment year, may
receive a one-year extension of its attainment date. Assuming these
conditions are again met the following year, the area may receive an
additional one-year extension. If the area has no more than one
exceedance in this final extension year, then it will have three years
of data indicating that it has attained the ozone standard.
    EPA has consistently taken this position in guidance and in our
approval of 1-hour ozone attainment demonstrations. Our ozone modeling
guidance, which was issued less than a year after the 1990 CAA
Amendments were enacted, requires States to model the ozone season
before the attainment date and not the third ozone season before the
attainment date.\19\ The ozone attainment demonstrations that EPA has
approved since the CAA Amendments of 1990 have been based on this
modeling guidance and show that there will be no violations in the
attainment year. See, for example, 61 FR 10921 (March 18, 1996) and 62
FR 1150 (January 8, 1997), proposed and final approval of California's
attainment plans for 7 nonattainment areas; 66 FR 54143 (October 26,
2001), approval of Pennsylvania's 1-hour ozone attainment plan for the
Philadelphia area; and 67 FR 30574 (May 7, 2002), approval of Georgia's
1-hour ozone attainment plan for Atlanta.
---------------------------------------------------------------------------

    \19\ See Chapter 6 (``Attainment Demonstrations'') of Guideline
for Regulatory Application of the Urban Air Shed Model (July 1991,
OAQPS, EPA).
---------------------------------------------------------------------------

    We took the same position on attainment demonstrations for the 8-
hour ozone standard promulgated in 1997 when we promulgated regulations
specifying the deadline for implementing emissions reductions for
purposes of attainment of that standard. Specifically, 40 CFR 51.908(d)
provides: ``For each nonattainment area, the State must provide for
implementation of all control measures needed for attainment no later
than the beginning of the attainment year ozone season.'' ``Attainment
year ozone season'' is defined as ``the ozone season immediately
preceding a nonattainment area's attainment date.'' 40 CFR 51.900(g).
    Third, we do not find that CARB's and SCAQMD's commitments to be
for a reasonable and appropriate period of time simply because the
aggregate emissions reductions will be in place at the beginning of
ozone season prior to the attainment date, but also because the
agencies have committed to take certain near-term regulatory actions in
support of those emissions reductions commitments. More specifically,
SCAQMD has committed to develop, adopt, and submit, and implement
specific control measures as expeditiously as possible. SCAQMD's
commitment includes adoption dates for the specific measures (the
latest of which calls for adoption in 2016) and implementation dates.
Likewise, CARB has committed to bring certain regulatory measures to
its Board for action on a certain schedule.
    Therefore, we continue to find the reliance of the 2012 AQMP on
these commitments to be acceptable because, among other reasons, we
find the commitments to be for a reasonable and appropriate period of
time.

Sustainable Communities Strategy (SCS)

    Comment 14: Earthjustice claims that the emissions reductions from
SCAG's Sustainable Communities Strategy (SCS) have been included in the
baseline but that such inclusion is not appropriate because SCAG has
not provided any information that the claimed emissions reductions will
come from enforceable measures nor has EPA approved the SCS as a
control measure. Earthjustice contends that the SCS should be submitted
as a control measure towards attainment of the 1-hour and 8-hour ozone
standards in the South Coast.
    Response 14: The SCS is a new requirement for Regional
Transportation Plans (RTPs) in California pursuant to state law (Senate
Bill 375). As described in the 2012 South Coast AQMP, the primary goal
of the SCS is to provide a vision for future growth in Southern
California that will decrease per capita greenhouse gas emissions from
automobiles and light trucks through integrated transportation, land
use, housing and environmental planning. This leads to strategies that
can help reduce per capita vehicle miles traveled over the next 25
years. While the SCS is intended to reduce GHG emissions, it will also
produce reductions in ozone precursors.
    SCAG's most recent adopted RTP, the 2012-2035 Regional
Transportation Plan/Sustainable Communities Strategy (RTP/SCS),
reflects SCS principles to achieve per capita emission reduction
targets. Earthjustice is correct that the baseline inventory for the
South Coast 2012 AQMP includes emissions reductions from the RTP/SCS to
the extent that it reflects the same population, employment, economic
activity, vehicle and transit activity forecasts and transportation
control measures as the RTP/SCS and those forecasts and measures are
projected to result in lower transportation-related emissions than
would have occurred under the RTP baseline case. However, because SCS
strategies are fully

integrated into the RTP/SCS, separate emissions reduction estimates
attributable to land use pattern changes cannot reliably be made apart
from those associated with the various forecasts, transportation
projects, and TCMs in the RTP/SCS. Distinguishing between emissions
reductions associated with the types of changes in land use development
patterns associated with SCS principles from those associated with
transportation projects and TCMs is confounded by the fact that, as
noted in the 2012 South Coast AQMP, the regional transportation system
is appropriately viewed on a systems-level basis, and not by its
components, since each of the individual transportation improvements
and strategies affect each other and the system.
    In addition, to the extent that the RTP/SCS reflects land use
policies, we note that we have historically allowed States to take into
account land use policies in their baseline (as opposed to being
specifically approved into the SIP) if those policies are not being
relied on as part of the control strategy. Specifically, we state:
``EPA believes that it would be appropriate to include a specific land
use policy in the land use assumptions made for the initial forecast
[of future emissions] only if:
    A. The policy meets one of the following conditions:
     It has already been adopted by an appropriate
jurisdiction, or
     the policy is planned and there is an enforcing mechanism
to ensure it will happen; and
    B. The effects of the policy haven't already been accounted for in
the land use assumptions--that is, you are not double counting.'' \20\

be found at the following Web site: http://www.epa.gov/oms/stateresources/policy/transp/landuse/r01001.pdf.
---------------------------------------------------------------------------

    In this instance, to the extent that the RTP/SCS embodies certain
land use policies, those policies are not being relied upon as part of
the control strategy to demonstrate attainment of the 1-hour ozone
standard in the South Coast by the applicable attainment date and are
enforceable through mechanisms provided in SB 375, and the effects of
the policies have not already been accounted for in the land use
assumptions.

Solar Power

    Comment 15: Noting ongoing litigation between PSPC and SCAQMD over
the 2012 AQMP, PSPC calls for adoption by SCAQMD of rules to implement
an Immediate Total Solar Conversion Plan, with full implementation by
2020, or 2023 at the latest, contending that that the Immediate Total
Solar Conversion Plan is cost effective and represents reasonably
available control technology (RACT), Best Available Control Technology
(BACT), and Best Available Retrofit Control Technology (BARCT). PSPC
asserts that California Health and Safety Code (CH&SC) section 40404.5
mandates a solar conversion plan within the South Coast.
    Response 15: For ozone nonattainment areas classified as moderate
or above, CAA section 182(b)(2) requires the implementation of
provisions that require the implementation of RACT on all major
stationary sources of VOC and for each VOC source category for which
EPA has issued Control Techniques Guideline (CTG) documents. CAA
section 182(f) requires that RACT under section 182(b)(2) also apply to
major stationary sources of NOX. In extreme ozone
nonattainment areas such as the South Coast, a major source is a
stationary source that emits or has the potential to emit at least 10
tons of VOC or NOX per year. CAA sections 182(e) and (f).
The current rulemaking does not address the RACT SIP for the South
Coast, thus the issue of whether a particular control is required for a
specific source or source category is not pertinent to this rulemaking.
With respect to the requirement to ensure implementation of emission
limits representing BACT, we note that, for federal law purposes, BACT
determinations are made in connection with preconstruction review and
permitting of new major sources or major modifications of existing
major sources under the provisions of the CAA and EPA regulations for
the Prevention of Significant Deterioration (PSD). As such, BACT is
relevant in the context of individual major source permit applications,
but not in the context of EPA's action on the regional air quality
plan.
    Though not relevant to this rulemaking, we note that we are
currently unaware of any sources that use solar power to control or
limit VOC or NOX emissions. SJVUAPCD has researched solar-
powered aeration for green waste composting, but recent discussions
with SJVUAPCD staff indicated that while this work shows promise, it is
still in the research phase.
    Lastly, our role in reviewing SIP revisions is to ensure that they
meet the applicable requirements of federal law, not state law, and
thus, the issue of whether state law, in this case, CH&SC section
40404.5, mandates a solar conversion plan within the South Coast and
whether the 2012 AQMP complies with the provisions of CH&SC section
40404.5 is not relevant for the purposes of our review of the 2012 AQMP
under CAA section 110(k).\21\ Similarly, the term ``Best Available
Retrofit Control Technology'' is a term established under state law,
and thus is also not relevant to our action on the 2012 AQMP.\22\
---------------------------------------------------------------------------

    \21\ CH&SC section 40404.5 states: ``The Legislature further
finds and declares that the south coast district, in fulfilling its
directive to require the use of best available control technology
for new sources, and in consideration of the state policy to promote
and encourage the use of solar energy systems, shall make reasonable
efforts to incorporate solar energy technology into its air quality
management plan in applications where it can be shown to be cost-
effective.''
    \22\ BARCT is defined in CH&SC section 40406: ``As used in this
chapter, ``best available retrofit control technology'' means an
emission limitation that is based on the maximum degree of reduction
achievable, taking into account environmental, energy, and economic
impacts by each class or category of source.''
---------------------------------------------------------------------------

III. Final Action

    Under section 110(k) of the CAA, and for the reasons discussed
above and in our May 23, 2014 proposal (see 79 FR 29712), the EPA is
approving certain ozone-related portions of the 2012 South Coast AQMP
as a revision to the California SIP. The relevant portions of the 2012
AQMP that are being approved include the updated control strategy for
the 1997 8-hour ozone standard and the demonstration of attainment of
the 1-hour ozone standard in the South Coast by December 31, 2022. In
so doing, we are approving the following commitments and measures upon
which the 1-hour ozone attainment demonstration relies as well as the
State's reliance on the approved control strategy for the 1997 8-hour
ozone standard:
     SCAQMD's commitments to develop, adopt, submit and
implement the measures as summarized in table 5 of the proposed rule,
subject to findings of infeasibility and measure substitution, and a
commitment to meet aggregate emissions reductions targets of 6 tpd of
VOC and 11 tpd of NOX by January 1, 2022;
     The new technology provisions (summarized in table 6 of
the proposed rule) through which the 2012 AQMP expects to achieve
emissions reductions of 17 tpd of VOC and 150 tpd of NOX in
the South Coast by January 1, 2022; and
     CARB's commitment to submit contingency measures by
January 1, 2019 as necessary to ensure that the emissions reductions
from new technology measures are achieved.
    In approving this SIP revision, EPA finds that an attainment date
of

December 31, 2022 is appropriate in light of the severity of the 1-hour
ozone problem in the South Coast and given the extent to which
emissions sources in the South Coast have already been controlled and
the difficulty of developing regulations and controlling additional
emissions. EPA also finds that the South Coast 1-hour ozone attainment
demonstration is based on reasonable estimates and forecasts of ozone
precursor emissions and appropriate photochemical modeling techniques
and assumptions and an acceptable control strategy.

IV. Statutory and Executive Order Reviews

    Under the Clean Air Act, the Administrator is required to approve a
SIP submission that complies with the provisions of the Act and
applicable Federal regulations. 42 U.S.C. 7410(k); 40 CFR 52.02(a).
Thus, in reviewing SIP submissions, EPA's role is to approve State
choices, provided that they meet the criteria of the Clean Air Act.
Accordingly, this action merely approves a state plan as meeting
federal requirements and does 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 Clean Air Act; and
     Does not provide EPA with the discretionary authority to
address disproportionate human health or environmental effects with
practical, appropriate, and legally permissible methods under Executive
Order 12898 (59 FR 7629, February 16, 1994).
    In addition, this rule 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 located in
the State, 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 November 3, 2014. Filing a petition for
reconsideration by the Administrator of this final rule does not affect
the finality of this action 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)).
