[EPA-R04-OAR-2012-0986; FRL-9903-32-Region 4]
Approval and Promulgation of Implementation Plans and Designation
of Areas for Air Quality Planning Purposes; Georgia; Redesignation of
the Atlanta 1997 8-Hour Ozone Moderate Nonattainment Area to Attainment
AGENCY: Environmental Protection Agency (EPA).
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: EPA is taking final action to approve a request submitted on
April 4, 2012, from the State of Georgia, through the Georgia
Environmental Protection Division (GA EPD), to redesignate the Atlanta,
Georgia, ozone nonattainment area (hereafter referred to as the
``Atlanta Area,'' or ``Area'') to attainment for the 1997 8-hour ozone
National Ambient Air Quality Standards (NAAQS). The Atlanta Area
consists of Barrow, Bartow, Carroll, Cherokee, Clayton, Cobb, Coweta,
DeKalb, Douglas, Fayette, Forsyth, Fulton, Gwinnett, Hall, Henry,
Newton, Paulding, Rockdale, Spalding and Walton Counties in their
entireties. EPA's approval of the redesignation request is based on the
determination that Georgia has met the criteria for redesignation to
attainment set forth in the Clean Air Act (CAA or Act). Additionally,
EPA is approving, as a revision to the Georgia State Implementation
Plan (SIP) a maintenance plan for the 1997 8-hour ozone standard for
the Atlanta Area, including new 2024 motor vehicle emission budgets
(MVEBs) for nitrogen oxides (NOX) and volatile organic
compounds (VOC). In this final notice, EPA also responds to comments
received on EPA's February 4, 2013, proposed rulemaking.
DATES: This rule will be effective on January 2, 2014.

I. What is the background for these final actions?
On April 4, 2012, Georgia submitted to EPA a request to redesignate
the Atlanta Area to attainment for the 1997 8-hour ozone NAAQS and to
approve Georgia's SIP revision containing a maintenance plan for the
Atlanta Area. In an action published on February 4, 2013 (78 FR 7705),
EPA proposed approval of Georgia's maintenance plan for the 1997 8-hour
ozone NAAQS, including the NOX and VOC MVEBs contained
therein. At that time, EPA also proposed to approve the redesignation
of the Atlanta Area to attainment. Additional background for today's
action is set forth in EPA's February 4, 2013, proposal. See 78 FR
7705.
As stated in the February 4, 2013, proposal, this redesignation
addresses the Atlanta Area's status solely with respect to the 1997 8-
hour ozone NAAQS, for which designations were finalized on April 30,
2004.\1\ See 69 FR 23857. On March 7, 2012, at 77 FR 13491, EPA
determined that the Atlanta Area attained the 1997 8-hour ozone NAAQS
by its June 15, 2011, applicable attainment date,\2\ and that the Area
was continuing to attain the ozone NAAQS based on quality-assured
monitoring data that was currently available.
---------------------------------------------------------------------------
\1\ On March 6, 2008, the Atlanta Area was reclassified to
moderate nonattainment for the 1997 8-hour ozone NAAQS. See 73 FR
12013.
\2\ On November 30, 2010, EPA published a final rule extending
the attainment date for the Atlanta Area until June 15, 2011. See 75
FR 73969.
---------------------------------------------------------------------------
EPA reviewed quality-assured ozone monitoring data from ambient
ozone monitoring stations in the Atlanta Area from 2008-2011, as
recorded in Air Quality System (AQS), and summarized the 3-year average
of the annual fourth highest daily maximum 8-hour average (i.e., design
value) for 2008-2010 and 2009-2011 in Tables 1 and 2. The data for 2012
were certified on May 1, 2013, and the design value for 2010-2012 is in
Table 3. The 2008-2010 design value establishes that the Area attained
by its attainment date and the 2009-2011, and the 2010-2012 design
values establish that the Atlanta Area continues to meet the 1997 8-
hour ozone NAAQS. Preliminary data provided by GA EPD for 2013 indicate
that the Atlanta Area continues to attain the 1997 8-hour ozone NAAQS
and further indicate that in 2013 no monitors in the Area recorded a
fourth-high ozone value above the 1997 8-hour ozone NAAQS. See Response
1 below for more detail on the 2013 preliminary data.

Effective July 20, 2012, EPA designated a portion of the Atlanta
Area for the 1997 8-hour ozone NAAQS as nonattainment for the 2008 8-
hour ozone NAAQS. This rulemaking does not address requirements for the
2008 8-hour ozone NAAQS. Requirements for the Area for the 2008 8-hour
ozone NAAQS will be addressed in the future.
II. What are the actions EPA is taking?
In today's rulemaking, EPA is approving: (1) Georgia's 1997 8-hour
ozone maintenance plan for the Atlanta Area, including the MVEBs
contained therein (such approval being one of the CAA criteria for
redesignation to attainment status); and (2) Georgia's redesignation
request to change the legal designation of the Atlanta Area from
nonattainment to attainment for the 1997 8-hour ozone NAAQS. The
maintenance plan is designed to demonstrate that the Atlanta Area will
continue to attain the 1997 8-hour ozone NAAQS through 2024. EPA's
approval of the redesignation request is based on EPA's determination
that Georgia has shown that the Atlanta Area meets the criteria for
redesignation set forth in CAA, sections 107(d)(3)(E) and 175A,
including the determination that the Atlanta Area has attained the 1997
8-hour ozone NAAQS. EPA's analyses of Georgia's redesignation request
and maintenance plan are described in detail in the February 4, 2013,
proposed rule (see 78 FR 7705), and in responses to comments in this
final rulemaking. As stated above, since the publication of EPA's
proposed rule, preliminary data available for 2013 show the Area
continues to attain the 1997 8-hour ozone NAAQS.
Consistent with the CAA, the maintenance plan that EPA is approving
includes the 2024 MVEBs for NOX and VOC for the Atlanta
Area. In this action, EPA is approving these NOX and VOC
MVEBs for the purposes of transportation conformity. For required
regional emissions analysis for 2024 and beyond, the applicable budgets
will be the new 2024 MVEBs.
Georgia has chosen to allocate a portion of the available safety
margin to the NOX and VOC MVEBs for 2024 for the Atlanta
Area. This allocation is 26.9 tons per day (tpd) and 29.4 tpd for
NOX and VOC, respectively. The remaining safety margins for
2024 are 276.69 tpd and 28.87 tpd NOX and VOC,
respectively.\3\
---------------------------------------------------------------------------
\3\ The remaining safety margins for NOX and VOC were
inadvertently listed in reverse order in the February 4, 2013,
proposal. See 78 FR 7716. The remaining safety margins for
NOX are 276.69 tpd and 28.87 tpd for VOC as correctly
stated in section vi of the proposed rulemaking notice.
---------------------------------------------------------------------------
The MVEBs, specified in tpd, included in the maintenance plan are
as follows:

VOC Emissions
------------------------------------------------------------------------
Base Emissions................................................ 62.56
Safety Margin Allocated to MVEB............................... 29.4

------------------------------------------------------------------------
In its February 4, 2013, proposed action, EPA noted that the public
comment period on the adequacy of the Atlanta Area MVEBs for the year
2024 (as contained in Georgia's submittal) began on February 29, 2012,
and closed on March 30, 2012. No comments were received during the
public comment period.
III. What are EPA's responses to comments?
EPA received one set of comments on the February 4, 2013, proposed
actions associated with the redesignation of the Atlanta Area for the
1997 8-hour ozone NAAQS. These comments were submitted by GreenLaw on
behalf of Mothers & Others for Clean Air, Sierra Club, and its members.
A summary of the comments and EPA's responses to them are provided
below.
Comment 1: The Commenter contends that EPA cannot redesignate the
Atlanta Area because the Agency relied on ambient air quality data from
2008-2011 to determine that the area has attained the NAAQS and did not
consider data from 2012. The Commenter states that the fourth-highest
ozone value at two monitors in the Atlanta Area exceeded 0.084 ppm in
2012. The Commenter claims that this shows that the Area ``has not
solved its ozone problem,'' and that EPA should require GA EPD to
certify the 2012 data before approving the final redesignation to
attainment.
Response 1: EPA disagrees with the Commenter's claim that the
monitored air quality in the Atlanta Area precludes EPA from approving
Georgia's request to redesignate the area to attainment. The quality-
assured monitoring data show that the Area continues to qualify for
redesignation. First, EPA has considered complete, quality-assured and
certified data for all monitors through 2012. These data have been
certified and show that the Area continues to attain the standard. In
accordance with 40 CFR Part 50, Appendix I, the determination as to
whether the Area meets the NAAQS is based on the three-year average of
the annual fourth-highest readings at a monitor, and not a monitor's
fourth-highest ozone value in a single year. No monitored value in a
single year can itself be a violation. A violation of the 1997 8-hour
ozone
[[Page 72043]]
NAAQS occurs when the three-year average of the annual fourth-highest
daily maximum 8-hour average ozone concentrations measured at a monitor
in an area exceeds 0.084 ppm (i.e., a violation occurs when the three-
year average exceeds 0.084 ppm at any one monitor in the area). This
three-year average is called the monitor's ``design value.'' Even if
the fourth-highest daily maximum at one monitor in one year exceeds
0.084 ppm, this does not constitute a violation. Only a three-year
average of monitor readings can establish that a violation has
occurred. Data must be quality-assured according to the data handling
and reporting convention described in 40 CFR Part 50, Appendix I before
it can be used to determine whether a violation has occurred. An
ambient air monitor reading that exceeds 0.084 ppm in any one year is
not determinative of a violation.
The certified data in Tables 1, 2, and 3 show that the Atlanta Area
is attaining the 1997 8-hour ozone standard. The 2012 data are now
certified, and the Area remains in attainment of the 1997 8-hour ozone
NAAQS because the 3-year design value is below 0.084 ppm. The
Commenter's reference to the East Confederate Avenue Site (AQS ID
131210055) and the Henry County Extension Office Site (AQS ID
131510002) do not call into question the Area's attainment status,
because the three-year 2010-2012 design values for these two monitors
remain below the 1997 8-hour ozone NAAQS. Moreover, GA EPD provided
preliminary data through October 2013 indicating that the Atlanta Area
continues to attain the 1997 8-hour ozone NAAQS and further indicate
that in 2013 no monitors in the Area recorded a fourth-high ozone value
above the 1997 8-hour ozone NAAQS.\5\
---------------------------------------------------------------------------
\5\ These preliminary data are included in the docket and are
provided for the purpose of indicating continued attainment of the
1997 8-hour ozone NAAQS. The data have not yet been quality-assured
or certified, and therefore may be subject to change.
---------------------------------------------------------------------------
Comment 2: The Commenter contends that Georgia's redesignation
submittal is flawed because it ``fails to demonstrate that past
reductions in levels of harmful ozone were not due to temporary factors
such as the Great Recession and weather'' and that EPA cannot approve
the redesignation request without a weather adjusted analysis. The
Commenter specifically contends that it would be arbitrary for EPA to
rely on ambient monitoring data from 2008-2011 to satisfy the section
107(d)(3)(E)(i) requirement that the Area attain the NAAQS because the
emissions and air quality from these years were influenced by temporary
economic conditions (the ``Great Recession'') and that EPA has failed
to provide any analysis to the contrary. According to the Commenter,
``[c]ertain monitors in the Atlanta nonattainment area have higher
values in 2012 than in 2008-2011--the years referenced by EPA in its
Proposed Rule--and the readings have been increasing as the economy
rebounds.'' The Commenter also contends that it is inappropriate to use
data from 2008-2010 to determine if the improvement in air quality is
due to permanent and enforceable reductions under section
107(d)(3)(E)(iii) because the data ``does not take into account
economic conditions and other considerations'' such as weather.
Response 2: As noted above, EPA, pursuant to established
regulations, uses a three-year cycle to determine attainment of the
1997 8-hour ozone NAAQS. The averaging of values over three years
serves to account for variations in meteorology and the economy from
year to year. See 40 CFR 50.10 and Appendix I to CFR part 50. Although
EPA's proposal referred to 2008-2010 data, EPA has shown that
additional monitoring data establish that the Atlanta Area has
continued to attain the 1997 8-hour ozone NAAQS beyond the attainment
period of 2008-2010. EPA's review of all data currently available,
including certified 2009-2011 data and now-certified 2010-2012 data,
establishes that the Area continued to attain the standard with 2009-
2011 and now-certified 2010-2012 data. This is the case despite the
fact that conditions in the 2012 ozone season were more conducive to
ozone formation than in many other previous years. EPA disagrees with
the Commenter's assertion that that two individual monitor readings in
2012 cast doubt on the Atlanta Area's attainment status. Nor does the
Commenter provide information to support its contention that the
improvement in air quality during this period was due to the economy
and favorable meteorological conditions rather than to measures the
State and EPA have undertaken to reduce emissions of ozone precursors.
To the contrary, the certified data show that the Area remained
continuously in attainment throughout three sets of three-year period,
during varying meteorological and economic conditions.
Regarding the Commenter's contention that economic conditions
influenced the 2008-2010 ambient ozone concentrations, annual
NOX emissions data for Georgia electric generating units
(EGUs) in 2008, emissions in the first year of the ``Great Recession,''
were in fact similar to emissions from these units for 2003-2007. See
Table 5 below.

Furthermore, NOx emission data for the 10 state VISTAS region from
2002-2009 demonstrate that mobile and non-road NOx emissions have
decreased substantially in Georgia and region-wide and to a much
greater extent than can be attributed to economic fluctuations during
this period. These reductions are attributable to permanent and
enforceable reductions from the numerous Federal and state mobile and
non-road measures implemented during this period. See Tables 6 and 7.

* From GA Regional Haze Plan Appendix C.3 Table 5 (page 15).
Regarding the Commenter's contention that weather influenced the
2008-2010 ambient ozone concentrations, EPA agrees that weather
conditions have an effect on ozone concentrations, both in terms of
increasing ozone and decreasing ozone. However, weather effects are not
controllable, and EPA determines compliance with the ozone NAAQS using
a three-year average to account for changes in meteorology. In the case
of Atlanta, the Area has continuously attained for three three-year
averaging periods, thereby reinforcing the conclusion that attainment
is due to permanent and enforceable reductions rather than variable
economic conditions or favorable meteorology.
Ozone season temperatures and precipitation are two readily
available parameters that can be used to evaluate the potential weather
impacts on ozone concentrations. Ozone is more readily formed on warm,
sunny days when the air is stagnant. Conversely, ozone production is
generally more limited when it is cloudy, cool, rainy, or windy.\6\
Table 8 provides temperature and precipitation data for Georgia for the
ozone seasons (March-October) from 2008-2012 obtained from the National
Oceanic and Atmospheric Administration's National Climatic Data Center
(NOAA NCDC). The data in Table 8 show that both average temperature and
precipitation varied significantly from 2008-2012.

Table 8 provides the following data: Average ozone season (March-
October) temperature and precipitation; deviation from the 118 year
average ozone season temperature and precipitation (termed the
``anomaly''); and the rank of the given year on the 118 year (1895-
2012) recorded history list. A rank of 118 is given to the hottest or
wettest year. The rank and anomaly data in Table 8 show that average
ozone season temperatures were below normal in 2008 and 2009 with
precipitation below normal in 2008 and much above normal in 2009.
Temperatures were much above normal and precipitation was much below
normal for the years 2010, 2011, and 2012. If weather was the
controlling factor for ozone concentrations, the levels of 2008-2010
ozone design values would be expected to be lower than the 2009-2011
design values. However, for six out of the nine monitoring sites listed
in Tables 1 and 2 above, the 2008-2010 design values are higher than
the 2009-2011 design values. Therefore, factors other than weather
appear to be controlling the ozone concentrations. Further, there was
nothing about the weather during the 2008-2010 three-year period that
would indicate that EPA cannot go forward with the proposed approval of
the Atlanta redesignation.
Additionally, 2012 was one of the hottest and driest years in the
recent past. See Table 8, above. In fact, a record-setting heat wave
occurred in late June through early July 2012, which resulted in high
ozone levels measured across the southeast, and yet (as indicated in
the Response to Comment 1 above), data for the 2010-2012 ozone season
show that the Atlanta Area continues to be in attainment of the 1997
ozone standard. This fact further supports EPA's position that weather
is not the controlling factor in the Area's attainment.
The analysis of meteorological conditions and emissions trends
discussed above, along with the analysis of permanent and enforceable
emissions reduction measures described in the proposed rulemaking and
in the Responses to Comment 3, below, demonstrate that the improvement
in air quality in the Atlanta Area is independent of weather or
economic factors.
Comment 3(a): The Commenter states that EPA relied on a number of
state-only Georgia rules as permanent and enforceable measures and
specifically refers to the Georgia Multipollutant Rule and the Smoke
Management Plan. The Commenter further states that ``[u]nless Georgia
submits these rules, and EPA adopts them into the enforceable
implementation plan, they cannot be relied upon for redesignation as
they are not enforceable by EPA or the public and they are not
permanent.''
Response 3(a): EPA did not rely on any state-only Georgia rules as
permanent and enforceable measures under section 107(d)(3)(E)(iii). The
Commenter correctly states that Georgia's Smoke Management Plan and
Georgia Rule (sss)--Multipollutant Rule are not incorporated into the
Georgia SIP and thus, EPA is not relying on emissions associated with
those rules as part of this redesignation. As noted in the proposed
rule, ``Georgia's smoke management plan is a state-only requirement and
is therefore not federally enforceable. This measure is not necessary
for the continued maintenance of the Atlanta nonattainment area.'' The
proposed rule also states that ``Georgia Rule (sss) has not been
submitted to EPA for approval into the SIP and is therefore not
federally enforceable.'' See 78 FR 7705.
While Georgia Rule (sss) may contribute to future NOX
reductions, which may help continue to assure maintenance, it did not
contribute to NOX reductions that resulted in the Atlanta
Area becoming attainment for the 1997 8-hour ozone NAAQS. This is
demonstrated by the fact that EGUs contributed 63.62 tpd of the 606.78
tpd NOX emissions for 2008, or only about 10.5 percent of
the NOX emissions, based on the Atlanta attainment year
inventory.
Comment 3(b): The Commenter contends that reductions associated
with the NOX SIP Call are not permanent and enforceable
because the NOX SIP Call ``has been replaced and therefore
effectively no longer exists.'' The Commenter further states that the
NOX SIP Call ``is a cap and trade program, which means that
there are no actual reductions required from the emission sources in
the Metro-Atlanta nonattainment area. Rather, to the extent that any
reductions were once required, they could have happened only in areas
downwind that have little to no impact on the Metro-Atlanta area
nonattainment.'' The Commenter cites to the United States Court of
Appeals for the District of Columbia Circuit (D.C. Circuit) decision in
NRDC v. EPA, 571 F.3d 1245 (D.C. Cir. 2009) to support its position
that ``EPA cannot use cap-and-trade programs to satisfy an area-
specific statutory mandate.''
Response 3(b): EPA disagrees that the emission reductions resulting
from the NOX SIP Call are not permanent and enforceable
under section 107(d)(3)(E)(iii). The Commenter's contention that
reductions associated with the NOX SIP Call cannot be
considered permanent and enforceable because the rule ``has been
replaced and therefore effectively no longer exists'' is erroneous. As
noted in the proposal, even though EPA discontinued the NOX
Budget Trading Program when it promulgated CAIR, ``all states
regardless of the current status of their regulations that previously
required participation in the NOX Budget Trading Program
will remain subject to all of the requirements in the NOX
SIP Call even if the existing CAIR ozone season trading program is
withdrawn or altered.'' See 78 FR 7712. Participation in the CAIR ozone
season trading program is one acceptable way for states to meet their
NOX SIP Call obligations, but obligations under the
NOX SIP Call exist independent of CAIR and are independently
permanent and enforceable. EPA further explained in the proposal that
the anti-backsliding provisions of 40 CFR 51.905(f) specifically
provide that the provisions of the NOX SIP Call, including
the statewide NOX emission budgets, continue to apply after
revocation of the 1-hour NAAQS. EPA therefore does not agree with the
Commenter that reductions associated with the NOX SIP Call
are not permanent and enforceable because of the status of the rule.
[[Page 72046]]
Although Georgia was not subject to the NOX SIP Call,
reductions from the NOX SIP Call in upwind states helped the
Atlanta Area achieve attainment.
EPA also disagrees that the Atlanta Area cannot be redesignated for
the 1997 8-hour ozone NAAQS solely because the NOX SIP Call
is a cap-and-trade program. The Commenter's reliance on NRDC v. EPA,
571 F.3d 1245 (D.C. Cir. 2009) is inapposite. The D.C. Circuit's
decision in that case does not support the Commenter's argument and is
entirely consistent with EPA's position here. That case addressed a
specific aspect of the cap-and-trade program, solely within the very
different context of EPA's determination that the NOX SIP
Call trading program presumptively satisfied the nonattainment
Reasonably Available Control Technology (RACT) requirement. The Court's
decision centered on whether the RACT requirement could be satisfied by
reductions outside the nonattainment area. The Court simply held that
because EPA had not shown the trading program would result in
sufficient reductions in a nonattainment area, its determination that
the program satisfied the nonattainment RACT requirement was not
supported.\8\ Id. at 1256- 58. The Court did not hold, or address the
issue, as Commenter suggests, of how emissions trading programs that
require emissions reductions--either inside or outside a nonattainment
area--and which result in air quality improvement, should be considered
in evaluating redesignation requests. Trading programs require total
mass emission reductions by establishing mandatory caps on total
emissions to permanently reduce the total mass emissions allowed by
sources subject to the programs, validated through rigorous continuous
emission monitoring and reporting regimes. The emission caps and
associated controls are enforced through associated SIP rules or
Federal implementation plans (FIPs). Any purchase of allowances and
increase in emissions by one source necessitates a corresponding sale
of allowances and either reduction in emissions or use of allowances by
another source. Given the regional nature of ozone, the corresponding
NOX emission and/or allowance reduction in one affected area
will have an air quality benefit that will compensate, at least in
part, for the impact of any emission increase in another affected area.
In this case, as shown in Tables 6 and 7 of this notice, the
NOX SIP Call and other Federal mobile and non-road control
regulations achieved measurable reductions in NOX emissions
in the states upwind from and affecting the Atlanta Area. For the
reasons explained above, reductions associated with the NOX
SIP Call are permanent and enforceable because states remain subject to
the requirements of that rule. EPA has therefore determined that with
regard to the reductions associated with the NOX SIP Call,
in accordance with section 107(d)(3)(E)(iii), ``the improvement in air
quality is due to permanent and enforceable reductions in emissions
resulting from implementation of . . . applicable Federal air pollutant
control regulations.'' Thus, EPA disagrees that the Commenter has
identified a basis on which EPA should disapprove Georgia's
redesignation request.
---------------------------------------------------------------------------
\8\ The Court specifically elected not to vacate the RACT
provision and left open the possibility that EPA may be able to
reinstate the provision for particular nonattainment areas if, upon
conducting a technical analysis, it finds the NOX SIP
Call results in greater emissions reductions in a nonattainment area
than would be achieved if RACT-level controls were installed in that
area. Id. at 1258.
---------------------------------------------------------------------------
Comment 3(c): The Commenter does not believe that EPA can rely on
CAIR or CSAPR to provide permanent and enforceable emissions reductions
under section 107(d)(3)(E)(iii). According to the Commenter, EPA cannot
rely on CAIR because it has been remanded, and cites to two prior
Federal Register notices in support of its position that EPA's proposed
reliance on CAIR as a permanent and enforceable measure for
redesignation is contrary to other EPA Region 4 actions. The Commenter
reiterates its position that emissions reductions associated with CAIR
cannot be considered permanent and enforceable because CAIR is a cap-
and-trade program (citing again to NRDC v. EPA for the proposition that
``cap and trade programs cannot be used to satisfy area-specific
mandates''). Specifically, the Commenter contends that, under CAIR,
``[a]ny emissions reductions impacting the Metro-Atlanta nonattainment
area achieved through CAIR could be lost through the purchase of
emissions credits or trading of credits'' and that ``[a]ny source could
decide at any time in the future to purchase emissions credits,
increasing its emissions and thus impacts to the Atlanta Area.'' The
Commenter contends that ``CAIR did not impose any reductions'' and that
the use of modeling in developing CAIR is unreliable because it used
assumptions about the economy, the weather, and international commodity
prices like the price of coal and natural gas. Instead, the Commenter
believes that EPA could impose unit specific emission limits for units
in and impacting the Atlanta Area, and argues that such limits would
not be redundant of reductions required by CAIR ``because CAIR did not
impose any reductions on these units.'' The Commenter also states that
``to the extent'' that EPA relies on reductions from CSAPR, that rule
has been vacated and EPA may not rely on reductions associated with
CSAPR for the purposes of this redesignation.
Response 3(c): EPA does not agree that emission reductions
associated with CAIR cannot be considered permanent and enforceable for
purposes of meeting the requirements of section 107(d)(3)(E)(iii).
Section 107(d)(3)(E) of the CAA sets out the requirements for
redesignation, and states in relevant part that the Administrator must
``determine[] that the improvement in air quality is due to permanent
and enforceable reductions in emissions resulting from implementation
of the applicable implementation plan and applicable Federal air
pollutant control regulations and other permanent and enforceable
reductions.'' 42 U.S.C. 7407(d)(3)(E)(iii).
EPA recognizes that the D.C. Circuit's remand of CAIR necessarily
means that CAIR will at some point cease to be in effect. However, EPA
disagrees that the Court's remand forecloses the Agency and states from
relying on CAIR for purposes such as redesignating an area from
nonattainment to attainment. Subsection (iii) of section 107(d)(3)(E)
is a backwards looking requirement; it requires that the attainment air
quality in the area is ``due to'' permanent and enforceable emission
reductions. The purpose of this requirement is to ensure that in
redesignating areas from nonattainment to attainment, EPA does not rely
on ephemeral, temporarily improved air quality that results from
circumstances such as temporary shutdowns of plants or reduced emission
rates because of slowed production. See Procedures for Processing
Requests to Redesignate Areas to Attainment,'' Memorandum from John
Calcagni, Director, Air Quality Management Division, September 4, 1992
(Calcagni Memorandum) at page 4. The structure of section
107(d)(3)(E)(iii) indicates that the Act generally considers reductions
resulting from SIPs and Federal regulations as permanent and
enforceable. It references ``other'' reductions that are comparable to
measures adopted into SIPs or federally adopted regulations and can
therefore also qualify as permanent and enforceable reductions,
indicating that, in general, SIP reductions and
[[Page 72047]]
reductions from Federal regulations are the types of reductions that
the Act views in the first instance as having the requisite permanence
and enforceability for purposes of redesignation.
Georgia's CAIR provisions can be found in Georgia Rule 391-3-
1-.02(12)--Clean Air Interstate Rule NOX Annual Trading
Program. On October 9, 2007, at 72 FR 57202, EPA approved Georgia's
CAIR provisions, including CAIR NOX allocations. These SIP
provisions are in place and are federally enforceable. And, because
CAIR has been in force since 2005, the monitoring data used to
demonstrate the Area's attainment of the 1997 8-hour ozone NAAQS by the
June 2011 attainment deadline were impacted by CAIR. CAIR reductions
began as early as 2005, with full program requirements beginning in
2009. CAIR was thus in place and federally enforceable at the time the
Atlanta Area began monitoring attainment, and it continues to remain in
place under the instruction of the Court in EME Homer City Generation,
L.P. v. EPA, 696 F.3d. 7 (D.C. Cir., 2012), which vacated CSAPR and
explicitly left CAIR in place until EPA implements a replacement rule.
With regard to the Federal Register notices cited by Commenter,
those notices pre-date the D.C. Circuit's decision in EME Homer City.
Thus, statements regarding CAIR in those notices would not be
appropriately applied to the Atlanta action because of the
significantly changed circumstances surrounding CAIR. It is not
unreasonable for the Agency to reassess its position about whether the
reductions of CAIR can be considered sufficiently permanent and
enforceable for purposes of redesignation, in light of the D.C.
Circuit's vacatur of CSAPR and its order that the Agency continue to
implement CAIR in EME Homer City. That decision significantly altered
the status of CAIR, particularly in the context of redesignations.
As noted in the proposed rule (78 FR 7712), EPA believes that
relying on CAIR emission reductions in order to redesignate the Atlanta
Area, which has been attaining the NAAQS for many years and continues
to maintain the standard, is precisely the type of ``reliance
interest'' that the D.C. Circuit was concerned about in ordering the
Agency to continue administering CAIR. EME Homer City, 696 F.3d at 38.
In addition, in its substantive holdings, the D.C. Circuit in EME Homer
City held that ``a SIP logically cannot be deemed to lack a `required
submission' before EPA quantifies the good neighbor obligation.'' Id.
at 32. Under this holding, states have no obligation to submit ``good
neighbor'' SIPs until EPA has quantified their ``good neighbor''
obligations and EPA may not promulgate a FIP to address such
obligations until the Agency first quantifies the state's obligations,
and provides the state an opportunity to submit a plan consistent with
that defined obligation. 696 F.3d at 28-37. The EME Homer City decision
thus significantly lengthens the time it will take to get in place
regulations to replace the remanded CAIR. Under the EME Homer City
decision, SIP provisions to replace CAIR could not go into effect until
EPA has undertaken analysis and rulemaking to define states'
obligations in accordance with the other statutory requirements
identified by the EME Homer City Court, provided states adequate time
to develop implementation plans consistent with the defined
obligations, and EPA has reviewed and approved the SIP submissions in
notice-and-comment rulemakings. Similarly, no FIP to replace CAIR could
go into effect unless EPA found a state failed to submit a SIP within
the time given to develop such implementation plans or disapproved such
a SIP submittal. It is not unreasonable for EPA to determine that in
light of these circumstances, CAIR will be in place for a significant
amount of time. EPA therefore disagrees with the Commenter that its
prior statements regarding the status of CAIR before the EME Homer City
decision dictate how the Agency must view CAIR after that decision.
In addition, the modeling EPA conducted for the CSAPR rulemaking
demonstrates that the Atlanta Area would have attained and will
continue to maintain the standard even without CAIR. The air quality
modeling analysis, which analyzed a base-case and future-year modeling
scenario in which neither CAIR nor CSAPR was in place demonstrated that
the Atlanta Area would have been able to attain and will be able to
maintain the 1997 8-hour ozone NAAQS in the absence of any transport
rule. See ``Air Quality Modeling Final Rule Technical Support
Document,'' Appendix B, B-8 to B-9. This modeling is available in the
docket for this redesignation action. Nothing in the EME Homer City
decision undermines that conclusion or suggests that the air quality
modeling conducted during the rulemaking was flawed.
EPA also disagrees with the Commenter that emission reductions
occurring within the relevant nonattainment area cannot be relied upon
for the purpose of redesignations simply because they are associated
with the emissions trading programs established in CAIR. As discussed
in Response to Comment 3(b), EPA does not agree that NRDC v. EPA
supports the Commenter's position. Although framed in terms of the
requirements of section 107(d)(3)(E)(iii), that is, the Act's
requirement that an area's current attainment is a result of permanent
and enforceable measures, the Commenter's concerns appear more focused
on potential future problems in the Atlanta Area. For instance, the
Commenter notes that reductions that were achieved through CAIR that
impacted the Atlanta Area ``could be lost'' because of future emissions
trading, and that sources could decide ``in the future'' to purchase
emissions credit and therefore have a negative impact on the Atlanta
Area. The Commenter's focus on future reductions under CAIR suggests
concern not with EPA's approval under section 107(d)(3)(E)(iii), but
rather the requirements for a fully approved maintenance plan in
section 107(d)(3)(E)(iv) and section 175A that require the state to
show that the area will maintain the standard for ten years following
redesignation. In the proposal, EPA provided projected emissions of
NOX and VOC, the precursors to ozone pollution, for the
Atlanta Area for the relevant maintenance period. See 78 FR 7714, tbls.
2-4. Under its existing suite of control measures, including CAIR,
Atlanta is attaining the 1997 8-hour ozone NAAQS. Over the maintenance
period, emissions for each precursor are expected to further decrease
in the Atlanta Area. If violations of the standard after redesignation
nevertheless occur, EPA has approved the contingency measures in the
maintenance plan to account for such events.
Further, evaluations have been made to see whether trading has
created emissions ``hot spots.'' For example, since the beginning of
the Acid Rain Program, there have been no emissions hot spots
identified or created as a result of the program (see ``The Acid Rain
Program Experience: Should We Be Concerned About SO2
Emissions Hotspots?'' at http://epa.gov/airmarkets/resource/acidrain-resource.html).
Additionally, states and localities may impose stricter limits on
sources to address specific local air quality concerns. For example,
Georgia has adopted a multipollutant rule for Electricity Generating
Units that control emissions of sulfur dioxide (SO2) and
NOX, and North Carolina has adopted its Clean Smokestacks
Act. Florida recently revised its Regional Haze Plan which imposed
additional restrictions on a number of facilities in the State.
[[Page 72048]]
These limits must be met regardless of a source's accumulated
allowances.
The Commenter's statement that ``CAIR did not impose any
reductions'' is simply incorrect, and indicates a lack of understanding
of cap-and-trade programs. In general, cap-and-trade programs provide
economic incentives for early reductions in emissions and encourage
sources to install controls earlier than required for compliance with
future caps on emissions. The flexibility under a cap and trade system
is not about whether to reduce emissions; rather, it is about how to
reduce them at the lowest possible cost. As explained above in Response
to Comment 3(b), trading programs require total mass emission
reductions by establishing mandatory caps on total emissions to
permanently reduce the total mass emissions allowed by sources subject
to the programs, validated through rigorous continuous emission
monitoring and reporting regimens. The emission caps and associated
controls are enforced through the associated SIP rules or FIPs. Any
purchase of allowances and increase in emissions by one source
necessitates a corresponding sale of allowances and either reduction in
emissions or use of banked allowances by another covered source. Given
the regional nature of ozone, the corresponding NOX emission
and/or allowance reduction in one affected area will have an air
quality benefit that will compensate, at least in part, for the impact
of any emission increase in another affected area. EPA disagrees with
the Commenter's suggestion that only specific emission limits on units
can be considered ``reductions.''
In fact, the actual data that EPA has evaluated in order to
conclude that the Atlanta Area has met the criteria for redesignation
shows that power plant emissions in both Atlanta and the surrounding
region have substantially decreased as a result of cap-and-trade
programs, including CAIR. The facts contradict the theoretical concerns
raised by the Commenter, and show that the emission trading programs,
combined with other controls, in fact worked to improve air quality in
the Area. Moreover, the NOX SIP Call and CAIR have
successfully reduced transported emissions contributing to ozone
nonattainment in areas across the country. Data collected from long-
term national air quality monitoring networks demonstrate that these
regional cap-and-trade programs have resulted in substantial
achievements in air quality caused by emission reductions from power
sector sources.\9\ In 2004, EPA designated 91 areas in the Eastern half
of the United States as nonattainment for the 8-hour ozone standard
adopted in 1997, using data from 2001-2003. Based on data gathered from
2009--2011, 90 of these original Eastern nonattainment areas show
concentrations below the 1997 ozone standard. Id. at 12. Many states
have sought and continue to seek redesignation of their nonattainment
areas, relying in part on the reductions attributable to these cap-and-
trade programs. See, e.g., 76 FR at 59607 (proposing to redesignate a
portion of the Chicago area for the 1997 8-hour ozone NAAQS), finalized
at 76 FR 76302, and 74 FR 63995 (redesignation of Great Smoky Mountain
National Park for the 1997 8-hour ozone NAAQS). The Commenter's
contention that EPA and Georgia may not rely on the substantial
emission reductions that have already occurred from these rules based
on a faulty and rigid interpretation of the CAA would impose a major
obstacle for nonattainment areas across the country that have achieved
attainment air quality because of the reductions required by the rules.
This would unnecessarily undermine a reasonable, proven, and cost-
effective approach to combating regional pollution problems.

Rain Program, and former NOX Budget Trading Program

(``2011 Environmental and Health Results Report'').
---------------------------------------------------------------------------
Of the federally-enforceable rules relied upon by Georgia in its
redesignation request, the Commenter singles out cap-and-trade programs
as insufficiently permanent and enforceable to meet the requirements
for redesignation. Measures that have been approved into Georgia's SIP
that have helped contribute to the Area's attainment of the 1997 8-hour
ozone standard include: Georgia Rule (yy)--Emissions of Nitrogen
Oxides, Georgia Rule (lll)--NOX from Fuel Burning Equipment,
Georgia Rule (rrr)--NOX from Small Fuel Burning Equipment,
and Georgia Rule (jjj)--NOX from EGUs. Federal rules relied
upon by Georgia in its redesignation request include Tier 2 vehicle
standards, Large Non-road Diesel Engines Rule, and nonroad spark-
ignition engines and recreational engines standards. See 78 FR 7705.
There is inherent flexibility in nearly all of these requirements
relied upon in Georgia's redesignation request, including Federal
transportation control measures and SIP emission rate limits, also
known as ``command-and-control'' regulations. For example, the rules do
not and cannot account for when and where people drive their cars, nor
do they dictate that consumers in a certain area invest in newer,
lower-emitting cars. Similarly, emission rate limits limit the rate of
emissions per unit of fuel consumed, or parts per million of emissions
in the exhaust but do not regulate throughput or hours of operation of
the regulated sources. It would be unworkable for EPA to disqualify a
requirement as ``permanent and enforceable'' for the purposes of
redesignation simply because the requirement did not require the exact
same pollutant emission reduction every hour of every day of every
year. The Atlanta Area relied on a suite of requirements that, while
inherently allowing for some flexibility, has collectively served to
bring the Area into, and to maintain, attainment of the NAAQS.
Moreover, the Commenter's concerns about modeling with regard to
the CAIR rulemaking are not germane to this redesignation; it is the
Atlanta Area's monitored attainment and continued monitored attainment
that EPA is relying on in finalizing redesignation for this area, as
opposed to modeling that EPA conducted for the CAIR rulemaking and any
assumptions about commodity prices and the economy that necessarily
went into that rulemaking.
Finally, EPA is not relying on CSAPR for continued maintenance of
the Area and in approving this redesignation of Atlanta. As such, there
is no basis to conclude that it would be improper to redesignate the
Area even in the absence of CSAPR.
Comment 4(a): The Commenter states that EPA cannot approve the
emissions inventory under CAA section 182(a)(1) because ``portions of
the emissions inventory were estimated, as opposed to being based on
actual emissions.''
Response 4(a): In a prior, separate rulemaking, EPA has already
taken final action to approve the emissions inventory for the Atlanta
Area under section 182(a)(1). See 77 FR 24399. It is settled law that,
in evaluating redesignations, EPA is not required to review already-
approved SIP revisions. EPA may rely on prior SIP approvals in
approving a redesignation request (Southwestern Pennsylvania Growth
Alliance v. Browner, 144 F.3d 984, 989-90 (6th Cir. 1998), Wall v. EPA,
265 F.3d 426 (6th Cir. 2001)), plus any additional measures it may
approve in conjunction with a redesignation action (see Calcagni
Memorandum at page 3; 68 FR 25426 (May 12, 2003) and citations
therein). In EPA's prior rulemaking action on Atlanta's emissions
inventory,
[[Page 72049]]
EPA provided an opportunity for public notice and comment; and no
comments were submitted. EPA approved the emissions inventory as
consistent with the requirements of section 182(a)(1), the CAA
implementing regulations, and EPA guidance for emission inventories.
Thus, any comments regarding EPA's approval of the emissions inventory
are untimely and unfounded. EPA notes that the maintenance
demonstration accompanying the redesignation request includes an
attainment year inventory that serves as the base year for projecting
emissions over the maintenance period. The State has shown, and EPA
agrees, that this inventory is accurate and comprehensive. Since EPA
has already approved the inventory under section 182(b)(1), no
additional approval is necessary.
Comment 4(b): The Commenter further disputes the approvability of
the emissions inventory because ``[t]here is no indication that EPA
accounted for the increase in NOX and VOC emissions that
will result from use of E15 when it approved GA EPD's estimate of on-
road emissions as satisfying the section 182(a)(1) comprehensive
emissions inventory requirement.''
Response 4(b): EPA does not believe that the Commenter's concerns
regarding E15 use in the Atlanta Area and increases in VOC and NOx
emissions are supported. The Commenter's concerns appear to derive not
from the emissions inventories that EPA approved, but rather from the
possibility that the future increases in NOX and VOC that
the Commenter believes might result from the use of E15. Therefore,
this appears to be a concern regarding future maintenance of the
standard rather than a concern about the approvability of the prior
emissions inventories. In any event, EPA believes that the Commenter's
concerns regarding E15 use in that Atlanta Area and potential resulting
increases in VOC and NOX emissions are unfounded. Georgia
has a state fuel rule that covers 45 counties that is inclusive of the
20-county Atlanta Area that was designated nonattainment for the 1997
8-hour ozone NAAQS. Regardless of the allowance for increased ethanol
in conventional fuel (i.e., E15), Georgia must comply with the
requirements of its state fuel rule which was put in place specifically
to reduce fuel-related VOC and NOX emissions for the Atlanta
Area. EPA approved Georgia's fuel rule into the Georgia SIP for the
purposes of meeting 1-hour ozone NAAQS (see 67 FR 8200 (February 20,
2002)), and this rule remains in Georgia's federally-enforceable SIP.
GA EPD modeled the Georgia fuel rule requirements in developing the
emissions inventory for the maintenance plan.
In 2010 and 2011, EPA granted partial waivers for use of E15 in
model year (MY) 2001 and newer light-duty motor vehicles (75 FR 68094
and 76 FR 4662). As discussed in the partial waiver decisions, there
may be some small emission impacts from the use of E15. E15 is expected
to cause a small immediate emissions increase in NOX
emissions. However, due to its lower volatility than the E10 currently
in-use, its use is also expected to result in lower evaporative
emissions. Other possible emissions impacts may be from the misfueling
of E15 in vehicles or engines for which its use is not approved, i.e.
MY2000 and older motor vehicles, heavy-duty engines and vehicles,
motorcycles and all nonroad engines, vehicles and equipment. EPA
promulgated a separate rule dealing specifically with the mitigation of
misfueling to reduce the potential emissions impacts from misfueling
(76 FR 44406).
However, the E15 partial waivers do not require that E15 be made or
sold and it is unclear if and to what extent E15 may even be used in
Georgia. Even if E15 is introduced into commerce in Georgia,
considering the likely small and offsetting direction of the emission
impacts, the limited set of motor vehicles approved for its use, and
the measures required to mitigate misfueling, EPA believes that any
potential emission impacts of E15 will be less than the maintenance
plan safety margin by which Georgia shows maintenance of the 1997 8-
hour ozone NAAQS. As shown in Tables 9 and 10, total VOC and
NOX emissions decrease significantly from 2008 through 2024,
the last year of the maintenance plan. During this period, total
NOX emissions decrease 50 percent (by 303 tpd) and VOC
emissions decrease 12 percent (by 58 tpd). It should be noted that EPA
recently proposed the Tier 3 vehicle emissions and fuel standards
program. The proposal calls for more stringent limits on emissions of
NOX and VOCs from new motor vehicles beginning with the 2017
model year resulting in emissions reductions as these vehicles enter
the fleet. The proposal also calls for reducing the annual average
sulfur content of gasoline from 30 ppm to 10 ppm beginning on January
1, 2017. Reductions in the sulfur content of gasoline would enable
automobile manufacturers to comply with the proposed vehicle emissions
standards, and would also achieve significant immediate benefits by
reducing emissions from existing vehicles. The maintenance plan does
not include emissions reductions from these proposed regulatory
changes. If the Tier 3 vehicle emissions and fuel standards program is
finalized as proposed, it would result in additional reductions in on-
road emissions of NOX and VOC that go beyond those which are
consistent with maintenance of the 1997 ozone NAAQS in the Atlanta
Area.

Georgia used EPA's approved motor vehicle emissions factor model,
MOVES2010, to prepare the on-road inventory. Additionally, EPA has
concluded that GA EPD used the appropriate parameters for modeling the
Georgia fuel rule and that the emissions inventories are approvable.
Comment 5(a): The Commenter claims that EPA cannot approve the
maintenance plan because it ``would need to show, at a minimum, [that]
the 2014, 2017, 2020, and 2024 emissions will be significantly below
the 2012 emissions'' given that ``2012 emission levels result in
ambient concentrations over the NAAQS.''
Response 5(a): The Commenter's contention that maintenance can be
shown only by emissions that are ``significantly below the 2012''
emissions is based solely on the same misguided premise as its argument
in Comment 1: that two monitor readings in 2012 showed concentrations
above the level of the 1997 8-hour ozone NAAQS. As EPA explained in
Reponses to Comments 1 and 2 above, these readings did not establish
violations or alter the Area's attainment status, and the Area
continued to attain the 1997 8-hour ozone NAAQS in 2012. These readings
also in no way undermine the validity of the attainment year emissions
inventory, which remains the benchmark for showing the levels of
emissions that are needed to maintain the NAAQS. Consequently, the Area
need not, as the Commenter claims, show that emissions levels in the
future will be significantly lower in order to demonstrate continued
attainment. Therefore, the State met the criteria for demonstrating
maintenance by establishing its attainment inventories at the time of
the development of the maintenance plan and showing that future
projected emissions remain at or below the attainment emissions levels.
See Wall v. EPA, supra.
For its maintenance demonstration, Georgia used the 2008 National
Emissions Inventory (NEI) as base year emissions inventory reflecting
one of the years in a three-year period (2008 -2011) when attainment
was reached. Georgia's maintenance plan projected that total emissions
during the 10-year maintenance period after redesignation will stay
below attainment year levels. The 2008 inventory, one of the years in
the three-year period in which the Area attained the 1997 8-hour ozone
NAAQS, is an appropriate inventory to be used to demonstrate
maintenance of the NAAQS.\10\
---------------------------------------------------------------------------
\10\ As explained in the Calcagni Memorandum, ``[w]here a state
has made an adequate demonstration that air quality has improved as
a result of the SIP, the attainment inventory will generally be the
actual inventory at the time the area attained the standard.''
---------------------------------------------------------------------------
The Commenter asserts that ``2012 emissions levels result in
ambient concentrations above the NAAQS.'' Again, as set forth in
Response 1 above, a violation of the 1997 8-hour ozone NAAQS is based
on a three-year average, and does not, as the Commenter claims, result
from a one-year fourth high value. The 2010-2012 ozone season data
established that the Area continues to attain the 1997 8-hour ozone
NAAQS. Preliminary data for 2013 indicate continued attainment.
Moreover, the maintenance plan also provides a mechanism for
anticipating and preventing violations. For example, the maintenance
plan's Tier I contingency measures are triggered when ``the periodic
emission inventory updates reveal excessive or unanticipated growth
greater than 10 percent in emissions of either ozone precursor over the
attainment or intermediate emissions inventories for the Atlanta
maintenance area (as determined by the triennial emission reporting
required by AERR).'' See 78 FR 7705.
Comment 5(b): The Commenter states its view that the maintenance
plan is not approvable because it is missing contingency provisions
that provide for the prompt correction of violations. According to the
Commenter, neither the Tier I nor the Tier II response ``occurs on a
prompt schedule, and several of the potential contingency measures
listed are inappropriate, inadequate, or vague.'' The Commenter goes on
to state that the Tier I response to prepare a comprehensive study to
develop corrective measures ``is not a corrective measure at all.'' The
Commenter states its belief that a period of 18 to 24 months, or more,
to adopt and implement corrective measures does not satisfy the
statutory requirement for prompt correction of violations under either
the Tier I or Tier II response, that the contingency measures listed in
the maintenance plan are ``too vague,'' and that the procedure for
selecting contingency measures has not been provided.
Response 5(b): EPA, consistent with its views set forth in many
other redesignation rulemakings, believes that the contingency measures
in the maintenance plan are adequate under section 175A(d). EPA
therefore disagrees with the Commenter's contention that the
contingency measures are vague and do not provide for prompt correction
of a NAAQS violation. Section 175A(d) of the CAA requires that a
maintenance plan include such contingency provisions, ``as the
Administrator deems necessary,'' to assure that the state will promptly
correct a violation of the NAAQS that occurs after redesignation of the
area. See 42 U.S.C. 7505A(d). Unlike section 172(c)(9), which governs
contingency measures for nonattainment areas, section 175A does not
require the adoption of specific contingency measures that must take
effect without further action by the State or EPA. Instead, Congress
provided EPA with the discretion to determine the form and timing of
the contingency that are required. Section 175A(d) provides leeway for
EPA to take into account the need of a state to assess, adopt, and
implement contingency measures if and when a violation occurs after an
area's redesignation to attainment. Therefore, in accordance with the
discretion accorded it by statute, EPA may allow reasonable time for
states to analyze data and address the causes and appropriate means of
remedying a violation. In assessing what ``promptly'' means in this
context, EPA also may take into account time for adopting and
implementation of the appropriate measure. In the case of the Atlanta
Area, EPA reasonably concluded that 18-24 months constitutes a timeline
consistent
[[Page 72051]]
with prompt correction of a potential monitored violation. This
timeframe also conforms with EPA's many prior rulemakings on acceptable
schedules for implementing section 175A contingency measures. EPA has
long exercised this discretion in its rulemakings on section 175A
contingency measures in redesignation maintenance plans, allowing as
contingency measures commitments to adopt and implement in lieu of
fully adopted contingency measures, and finding that implementation
within 18 to 24 months of a violation complies with the requirements of
section 175A. See recent redesignations such as Indianapolis Area 1997
Annual PM2.5 standard (76 FR 59512, 59522 (Sept. 27, 2011));
Baton Rouge Area 1997 8-hour ozone standard (76 FR 74000 (Nov. 30,
2011) (final); 76 FR 53853, 53869 (Aug. 30, 2011) (proposed));
Crittenden County, Arkansas portion of the Memphis Area 1997 8-hour
ozone standard (75 FR 14077 (Mar. 24, 2010) (final); 75 FR 2091, 2100
(Jan. 14, 2010) (proposal)); 76 FR 79579, 79590 (Dec. 22, 2011)
(proposed)); Hickory-Morganton-Lenoir Area 1997 Annual PM2.5
standard, 76 FR 71452 (Nov. 18, 2011) (final); 76 FR 58210, 58222
(Sept. 20, 2011) (proposed)). Section 175A does not establish any
deadlines for implementation of contingency measures after
redesignation to attainment. It also provides far more latitude than
does section 172(c)(9), which applies to a different set of contingency
measures applicable to nonattainment areas. Section 172(c)(9)
contingency measures must ``take effect . . . without further action by
the State or [EPA].''
EPA has consistently applied this interpretation of section 175A
since its announcement in a September 4, 1992, Calcagni Memorandum
(noting that a State is not required under 175A ``to have fully adopted
contingency measures that will take effect without further action by
the State in order for the maintenance plan to be approved''), and two
U.S. Circuit Courts of Appeal have agreed with the Agency. In Greenbaum
v. EPA, the U.S. Court of Appeals for the Sixth Circuit endorsed the
Calcagni Memorandum's statements regarding contingency measures for
175A maintenance plans and noted that EPA ``has been granted broad
discretion by Congress in determining what is `necessary to assure'
prompt correction'' under this section. 370 F.3d 527, 540 (6th Cir.
2004). The Court also stated that ``no pre-determined schedule for
adoption of the measures is necessary in each specific case.'' Id. In
Sierra Club v. EPA, the U.S. Court of Appeals for the Seventh Circuit
agreed with Greenbaum on these issues and identified the rationale
behind the discretion afforded to EPA and the states in the timing and
development of contingency measures, noting that ``[i]ntelligent
decisions may depend on the nature of future developments.'' 375 F.3d
537, 540 (7th Cir. 2004) (also noting that the ``statute does not call
for any particular degree of precision in the period after attainment .
. . so again, the EPA (and the affected states) had choices to make,
choices that may be gainsaid only if obviously misguided.''). The CAA
does not specify the requisite nature, scope, specificity, or number of
contingency measures to be included in a maintenance plan under section
175A. It is for EPA to determine whether the state has given adequate
assurance that it can promptly correct a violation. The State has
committed to remedy a future violation,\11\ and included measures to
address future violations and a timeline for promptly completing
adoption and implementation. For example, Georgia included a
consideration of expansion of RACT for point sources of VOC and NOx,
specifically the adoption of new and revised RACT rules based on Groups
II, III and IV control technique guidelines (CTGs) as a possible
contingency measure to implement. This identification of measures is
sufficiently specific while allowing for latitude in potential scope.
This will enable the State to address a range of potential sources and
differing degrees and types of violations. EPA believes that the
contingency measures set forth in the submittal, combined with the
State's commitment to an expeditious timeline and process for
implementation, provide assurance that the State will promptly correct
a future violation. Given the uncertainty as to timing, degree, and
nature of any future violation, EPA believes that the contingency
measures set forth adequately balance the need for flexibility in the
scope and type of measure to be implemented with the need for
expeditious state action.
---------------------------------------------------------------------------
\11\ In the context of this rulemaking, a future violation
indicates that the Tier II trigger is activated.
---------------------------------------------------------------------------
Given the discretion provided to EPA and the states under section
175A(d), the need for flexibility in developing appropriate contingency
measures in light of potential future developments, and the need for an
appropriate amount of time to develop and adopt these measures, EPA has
determined that Georgia's maintenance plan satisfies all applicable
requirements.
The maintenance plan for the Atlanta Area contains two different
types of contingency measures. The ``Tier I'' response, is not required
under section 175A, and therefore not subject to its criteria. The Tier
I response is triggered before any violation has occurred. It is
designed not to correct a violation, but to anticipate and evaluate
circumstances that may prefigure a violation.\12\
---------------------------------------------------------------------------
\12\ Specifically, the ``Tier I'' response in the Atlanta
maintenance plan is triggered: (1) when any quality-assured 8-hour
ozone monitoring reading exceeds 0.084 ppm at an ambient air
monitoring station in the Atlanta maintenance area; or (2) if the
periodic emission inventory updates reveal excessive or
unanticipated growth greater than 10 percent in ozone precursors
emissions in the Atlanta maintenance area.
---------------------------------------------------------------------------
Georgia's Tier II contingency measures, by contrast, are triggered
by a violation of the NAAQS. It compels the State to first conduct a
comprehensive study to determine what contingency measures are required
for the maintenance of the ozone NAAQS. Georgia must submit this study
to EPA for review as expeditiously as practicable but no later than
nine months after the trigger date. The State must adopt and implement
measures within 18 to 24 months after the trigger occurs. In addition
to setting these specific timing requirements, the maintenance plan
(see page 37 of the narrative) also lists a number of measures (e.g.,
expansion of RACT for point sources of VOC and NOx, specifically the
adoption of new and revised RACT rules based on Groups II, III and IV
CTGs) that Georgia may select as a contingency measure (see the
proposed rule for this action at 78 FR 7716 for a complete list). In a
September 20, 2013 letter to EPA that has been placed in the docket for
this action, GA EPD confirms that it commits to address and correct any
violation of the 1997 8-hour ozone NAAQS as expeditiously as
practicable, and no later than 24 months from trigger activation. For
additional details pertaining to the State's commitments regarding
contingency measures, see the September 20, 2013 letter from GA EPD,
included in the rulemaking docket. For all of the reasons set forth
above, EPA finds that, pursuant to CAA section 175A(d), the contingency
measures included in the maintenance plan and the schedule for the
development and adoption of measures are adequate to assure that the
State will promptly correct any future violation of the NAAQS that may
occur after redesignation.
Comment 6: The Commenter contends that EPA cannot approve the
redesignation request or maintenance plan without considering the
impacts
[[Page 72052]]
that climate change will have on ozone formation during the maintenance
period. The Commenter states that ``climate change will make our ozone
problems worse'' and cites to an April 2009 EPA document for support.
Response 6: EPA agrees that climate change is a serious
environmental issue; however, EPA does not agree that the redesignation
and maintenance plan at issue in today's notice are flawed because they
do not specifically consider the impacts of climate change on future
ozone concentrations. Given the potential wide-ranging impacts of
climate change on air quality planning, EPA is developing climate
adaptation implementation plans to assess the key vulnerabilities to
our programs (including how climate change might affect attainment of
national ambient air quality standards) and to identify priority
actions to minimize these vulnerabilities. With respect to climate
impacts on future ozone levels, EPA's Office of Air and Radiation has
identified as a priority action the need to adjust air quality modeling
tools and guidance as necessary to account for climate-driven changes
in meteorological conditions and meteorologically-dependent emissions.
However, the broad range of potential future climate outcomes and
variability of projected response to these outcomes limits EPA's
ability, at this time, to translate a general expectation that average
ozone levels will increase with rising temperatures to specific
``actionable'' SIP policies at any specific location. Additionally, EPA
believes that the natural variability in meteorological patterns will
have a larger influence on ozone concentrations than climate influences
over the relatively short-term SIP maintenance period. Thus, EPA
believes it is appropriate to rely upon the existing air quality
modeling tools and guidance and applicable CAA provisions to ensure
that ozone maintenance areas do not violate the NAAQS (as a result of
climate change or any other cause). In addition, in spite of the
uncertainty associated with short-term climate change impacts on ozone
concentrations, the projected emissions reductions of 50 percent for
NOx and 12 percent for VOC in the Atlanta Area over the next 10 years
are so large that they would overwhelm any potential climate change
impacts on ozone. EPA therefore believes that climate change will not
impact the ability of the Atlanta Area to maintain the 1997 8-hour
ozone NAAQS.
Comment 7: The Commenter asserts that EPA cannot redesignate the
Atlanta Area or approve the maintenance plan because the Area ``does
not have SIP approved contingency measures for VOCs and NOx, an
attainment demonstration and reasonable further progress for VOC and
NOx.'' According to the Commenter, ``the contingency measures should
have already been triggered or at most may be triggered this year if
Metro-Atlanta's design value exceeds 0.084 ppm'' which distinguishes
the Atlanta Area from prior actions where ``EPA has claimed that these
provisions do not matter because if any area is attaining, these
requirements would not apply anyway.'' The Commenter believes that
``all provisions that were in the nonattainment SIP would need to
become applicable again'' if the Area violates the NAAQS in the future,
and that ``under EPA's interpretation, there are no provisions that
were in the SIP before redesignation that will become effective again
if the area falls out of compliance with the NAAQS.''
Response 7: On June 23, 2011 (76 FR 36873), EPA determined that the
Atlanta Area had attained the 1997 8-hour ozone NAAQS based on 2008-
2010 monitoring data. Under 40 CFR 51.918, upon a finding that the area
is attaining the standard, requirements for SIP submissions linked to
attainment demonstrations, RFP, and attainment plan contingency
measures are suspended for so long as the area is attaining the
standard.\13\
---------------------------------------------------------------------------
\13\ EPA described its interpretation in a May 10, 1995
memorandum from John S. Seitz, Director, Office of Air Quality
Planning and Standards, entitled ``Reasonable Further Progress,
Attainment Demonstration, and Related Requirements for Ozone
Nonattainment Areas Meeting the Ozone Ambient Air Quality Standard''
(hereafter referred to as the ``Seitz Memorandum''). See also the
discussion and rulemakings cited in EPA's Final Rule to Implement
the 8-Hour Ozone NAAQS--Phase 2, 70 FR 71612, 71644-71646 (November
29, 2005). The Tenth, Seventh and Ninth Circuits have upheld EPA
rulemakings applying the Clean Data Policy. See Sierra Club v. EPA,
99 F. 3d 1551 (10th Cir. 1996); Sierra Club v. EPA, 375 F.3d 537
(7th Cir. 2004); and Our Children's Earth Foundation v. EPA, No. 04-
73032 (9th Cir. June 28, 2005) (memorandum opinion). As explained in
the Seitz Memorandum, EPA believes it is appropriate to interpret
the more specific attainment demonstration and related provisions of
subpart 2 in the same manner. See Sierra Club v. EPA, 99 F.3d. 1551
(10th Cir. 1996).
---------------------------------------------------------------------------
In addition, in the context of redesignations, EPA has long
interpreted requirements related to attainment planning (e.g.,
attainment demonstrations, RFP, and attainment plan contingency
measures) as not applicable for purposes of redesignation. In the
General Preamble EPA stated that: [t]he section 172(c)(9) requirements
are directed at ensuring reasonable further progress (RFP) and
attainment by the applicable date. These requirements no longer apply
when an area has attained the standard and is eligible for
redesignation. Furthermore, section 175A for maintenance plans provides
specific requirements for contingency measures that effectively
supersede the requirements of section 172(c)(9) for these areas.
``General Preamble for the Interpretation of Title I of the Clean Air
Act Amendments of 1990,'' (General Preamble) 57 FR 13498, 13564 (April
16, 1992). See also Calcagni Memorandum (dated 9/4/1992) at page 6.
(``The requirements for reasonable further progress and other measures
needed for attainment will not apply for redesignations because they
only have meaning for areas not attaining the standard.'').
In any event, EPA has previously determined that the Atlanta Area
attained by its attainment date (77 FR 13491), and therefore, no
contingency measures under the requirements of section 172(c)(9) can be
triggered, since those ``contingency measures are directed at ensuring
RFP and attainment by the applicable date.'' Id. at 13564.
The State must continue to operate an appropriate monitoring
network, in accordance with 40 CFR part 58, to verify the attainment
status of the Area. The air quality data relied upon to determine that
the Area is attaining the ozone standard must be consistent with 40 CFR
part 58 requirements and other relevant EPA guidance and recorded in
EPA's AQS.
As stated in Response 1, the Area remains in attainment of the 1997
8-hour ozone NAAQS, and the 2010--2012 quality-assured three-year
design value remains below 0.084 ppm. Preliminary data for 2013 show
continued attainment; therefore, no additional measures have been
triggered. Even if approved section 172(c)(9) contingency measures were
contained in the SIP, these measures are undertaken solely to address a
failure to attain by the Area's attainment date. For an area like the
Atlanta Area that has attained by its attainment date, no 172(c)(9)
contingency measures would be triggered by a violation that occurred
subsequently. After attainment, section 172(c)(9) contingency measures
are no longer deployed. Because the Area qualifies for redesignation,
the 175A maintenance plan approved today ensures that GA EPD will adopt
and implement any required measures in accordance with the schedule and
procedure for adoption and implementation of contingency measures.''
See 78 FR 7705.
Comment 8: The Commenter states that ``EPA has failed to conduct an
adequate analysis with respect to the
[[Page 72053]]
1997 annual PM2.5 NAAQS, the 2006 24-hour PM2.5
NAAQS, the 1-hour NOX NAAQS, the 1-hour SO2
NAAQS, and the 2008 8-hour ozone NAAQS'' and that without such an
analysis, ``EPA cannot ensure that redesignation will not interfere
with attainment of these NAAQS and thus cannot approve the
redesignation.'' The Commenter continues by stating ``EPA's
redesignation of Metro-Atlanta will delay attainment of the 2008 ozone
NAAQS because the 2012 ambient data proved that the current emission
limits are not adequate to maintain the 1997 NAAQS much less the 2008
NAAQS. Thus, if EPA does not approve the redesignation request, Georgia
EPD will have to provide for additional emission reductions of ozone
precursors. These emission reductions will assist in attaining the 2008
ozone NAAQS as quickly as possible.''
Response 8: First, as set forth earlier in other responses to
comments, the 2012 data do not ``prove that the current emissions
limits are not adequate to maintain the 1997 NAAQS . . . .'' The data
for 2012 establish, and preliminary data for 2013 also indicate, that
current emissions levels are consistent with continued attainment of
the 1997 8-hour ozone NAAQS. EPA does not agree that additional
emissions reductions are required in order for the Area to qualify for
redesignation. EPA has also evaluated the redesignation in relation to
the requirements of section 110(l) and believes that redesignation is
consistent with the provisions of that section. Section 110(l) provides
in part: ``[t]he Administrator shall not approve a revision of a plan
if the revision would interfere with any applicable requirement
concerning attainment and reasonable further progress . . ., or any
other applicable requirement of this chapter.'' 42 U.S.C. 7410(l). EPA
does not believe it is necessary to conduct an analysis with respect to
the impact of the redesignation on the 1997 annual PM2.5
NAAQS, the 2006 24-hour PM2.5 NAAQS, the 1-hour
NOX NAAQS, the 1-hour SO2 NAAQS, and the 2008 8-
hour ozone NAAQS. Although EPA does not interpret section 110(l) as
requiring a full attainment demonstration for every SIP revision, the
Agency does consider section 110(l) requirements when acting on each
SIP revision. See, e.g., 70 FR 53, 57 (January 3, 2005); 70 FR 17029,
17033 (April 4, 2005); 70 FR 28429, 28431 (May 18, 2005); and 70 FR
58119, 58134 (October 5, 2005). In this instance, the redesignation
does not relax any existing control requirements, nor does it alter any
existing control requirements, and therefore, EPA concludes that this
redesignation will not interfere with attainment or maintenance of any
of these air quality standards. The Commenter did not provide any
information that would cause EPA to conclude that approval of Georgia's
redesignation will have any impact on the Area's ability to comply with
the 1997 annual PM2.5 NAAQS, the 2006 24-hour
PM2.5 NAAQS, the 1-hour NOX NAAQS, the 1-hour
SO2 NAAQS, and the 2008 8-hour ozone NAAQS.
As set forth above, Georgia's April 4, 2012, redesignation request
and maintenance plan for the 1997 8-hour ozone NAAQS do not revise or
remove any existing emissions limit for any NAAQS or remove any other
existing substantive SIP provisions. In fact, the maintenance plan
provided with the State's submission demonstrates a decline in the
ozone precursors (e.g., NOX and VOC) emissions over the
timeframe of the initial maintenance period.\14\ Furthermore, EPA
designated 15 of the 20 counties in the 1997 8-hour ozone area as
nonattainment for the 2008 8-hour ozone NAAQS. With this nonattainment
designation, EPA notes that, even after the redesignation of the
Atlanta Area for the 1997 8-hour ozone NAAQS, 15 of these counties will
continue to have to comply with nonattainment new source review
requirements for ozone. For all of these reasons, EPA disagrees that
the Commenter has identified a rationale on which EPA could disapprove
of the SIP revision at issue.
---------------------------------------------------------------------------
\14\ EPA notes that the Atlanta Area does not have violating
monitors for the 1997 annual PM2.5 NAAQS, the 2006 24-
hour PM2.5 NAAQS, the 1-hour NOX NAAQS, the 1-
hour SO2 NAAQS, and that this Area has never been
designated nonattainment for 2006 24-hour PM2.5 NAAQS,
the 1-hour NOX NAAQS, or the 1-hour SO2 NAAQS.
---------------------------------------------------------------------------
IV. Why is EPA taking these actions?
EPA has determined that the Atlanta Area has attained the 1997 8-
hour ozone NAAQS and has also determined that all other criteria for
the redesignation of the Atlanta Area from nonattainment to attainment
of the 1997 8-hour ozone NAAQS have been met. See CAA section
107(d)(3)(E). One of those requirements is that the Atlanta Area has an
approved plan demonstrating maintenance of the 1997 8-hour ozone NAAQS.
EPA is also taking final action to approve the maintenance plan for the
Atlanta Area as meeting the requirements of sections 175A and
107(d)(3)(E) of the CAA. EPA is also approving the new NOX
and VOC MVEBs for the year 2024 as contained in Georgia's maintenance
plan for the Atlanta Area because these MVEBs are consistent with
maintenance of the 1997 8-hour ozone NAAQS in the Area. The detailed
rationale for EPA's findings and actions is set forth in the February
4, 2013, proposed rulemaking and in the Reponses to Comments and other
discussion in this final rulemaking.
V. What are the effects of these actions?
Approval of the redesignation request changes the legal designation
of the Atlanta Area from nonattainment to attainment for the 1997 8-
hour ozone NAAQS. EPA is modifying the regulatory table in 40 CFR
81.341 to reflect a designation of attainment for the counties. EPA is
also approving, as a revision to the Georgia SIP, the State's plan for
maintaining the 1997 8-hour ozone NAAQS in the Atlanta Area through
2024. The maintenance plan includes contingency measures to remedy
possible future violations of the 1997 8-hour ozone NAAQS, and
establishes NOX and VOC MVEBs for the year 2024 for the
Atlanta Area.
VI. Final Action
EPA is taking final action to approve the State of Georgia's
request for redesignation and change the legal designation the Atlanta
Area from nonattainment to attainment for the 1997 8-hour ozone NAAQS.
Through this action, EPA is also approving into the Georgia SIP the
1997 8-hour ozone maintenance plan for the Atlanta Area, which includes
for this Area the new NOX and VOC MVEB for 2024 for the
Atlanta Area of 126 tpd and 92 tpd, respectively.
VII. Statutory and Executive Order Reviews
Under the CAA, redesignation of an area to attainment and the
accompanying approval of the maintenance plan under CAA section
107(d)(3)(E) are actions that affect the status of geographical area
and do not impose any additional regulatory requirements on sources
beyond those required by state law. A redesignation to attainment does
not in and of itself impose any new requirements, but rather results in
the application of requirements contained in the CAA for areas that
have been redesignated to attainment. Moreover, 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 CAA.
Accordingly, these actions merely approve state law as meeting Federal
requirements and do not impose additional requirements beyond those
[[Page 72054]]
imposed by state or federal law. For these reasons, these actions:
Are 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);
do not impose an information collection burden under the
provisions of the Paperwork Reduction Act (44 U.S.C. 3501 et seq.);
are 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.);
do 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);
do not have Federalism implications as specified in
Executive Order 13132 (64 FR 43255, August 10, 1999);
are not an economically significant regulatory action
based on health or safety risks subject to Executive Order 13045 (62 FR
19885, April 23, 1997);
are not significant regulatory action subject to Executive
Order 13211 (66 FR 28355, May 22, 2001);
are 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,
do 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 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 January 31, 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).
