Determination of Failure To Attain by 2005 and Determination of
Current Attainment of the 1-Hour Ozone National Ambient Air Quality
Standards in the Baltimore Nonattainment Area in Maryland
AGENCY: Environmental Protection Agency (EPA).
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: EPA is issuing two separate and independent final
determinations related to the Baltimore 1-hour ozone nonattainment
area. First, EPA is determining that the Baltimore area previously
failed to attain the 1-hour ozone National Ambient Air Quality Standard
(NAAQS) by its applicable attainment deadline of November 15, 2005
(based on complete, quality-assured and certified ozone monitoring data
for 2003-2005). Second, EPA is also determining that the Baltimore area
is currently attaining the now revoked 1-hour ozone NAAQS based on
complete, quality-assured and certified ozone monitoring data for 2008-
2010 and continuing for 2009-2011. Thus, quality-assured ozone
monitoring data in the Air Quality System (AQS) show that the area has
been attaining the revoked 1-hour ozone standard since 2008. EPA's
determination that the area has attained the 1-hour ozone standard
obviates the need for submission of any contingency measures for
failure to attain that revoked standard.
DATES: This final rule is effective on July 12, 2012.

I. What actions EPA is taking?
EPA is issuing two separate and independent determinations for the
Baltimore area related to implementation of anti-backsliding
requirements for the 1-hour ozone NAAQS.\1\
---------------------------------------------------------------------------
\1\ Hereafter the term ``1-hour ozone NAAQS'' may be expressed
either as ``1-hour ozone NAAQS'' or as ``1-hour ozone standard.''
---------------------------------------------------------------------------
A. Determination of Failure To Attain the 1-Hour Ozone NAAQS by the
Applicable Attainment Date
Pursuant to EPA's authority to ensure implementation of 1-hour
ozone anti-backsliding requirements and section 301 of the Clean Air
Act (CAA), EPA is determining that complete, quality-assured and
certified data for 2003-2005 show that the Baltimore area previously
failed to attain the 1-hour ozone standard by its applicable November
15, 2005 attainment deadline.
B. Determination of Current Attainment of the 1-Hour Ozone NAAQS
EPA is determining that the Baltimore area is currently attaining
the 1-hour ozone standard. EPA's determination is based on the most
recent three-year periods of complete, quality-assured and certified
data, 2008-2010 and continuing in 2009-2011. Moreover, complete,
quality-assured and certified data show that the Baltimore area has
attained the 1-hour ozone standard since the 2006-2008 monitoring
period and for every three-year period since that time. Pursuant to
EPA's interpretation, as set forth in its Clean Data Policy \2\ and the
cases and regulations that embody it, EPA has determined that the
Baltimore area is no longer obliged to submit and implement the 1-hour
ozone contingency measure requirement of CAA section 172(c)(9).
---------------------------------------------------------------------------
\2\ See ``Reasonable Further Progress, Attainment Demonstration,
and Related Requirements for Ozone Nonattainment Areas Meeting the
Ozone National Ambient Air Quality Standard,'' (Clean Data Policy)
dated May 10, 1995.
---------------------------------------------------------------------------
In order to determine the area's air quality status for purposes of
this action, EPA reviewed ozone monitoring
[[Page 34811]]
air quality data from the states, in accordance with 40 CFR 50.9, 40
CFR part 50 appendix H, and EPA policy and guidance, as well as data
processing, data rounding and data completeness requirements. EPA's
review of the air quality data and related rationale for these
determinations are explained in the Notice of Proposed Rulemaking (NPR)
published in the Federal Register on February 1, 2012 (77 FR 4940)
(hereafter ``the NPR for this action'' or ``the February 1, 2012 NPR'')
and will not be restated here.
II. What is the background for these actions?
The Baltimore area is composed of Baltimore, Carroll, Harford and
Howard Counties and the City of Baltimore.\3\ The 1-hour ozone standard
designations were established by EPA following the enactment of the
1990 Amendments to the CAA. See 56 FR 56694, November 6, 1991. Each
area of the country that was designated nonattainment for the 1-hour
ozone NAAQS was classified by operation of law as marginal, moderate,
serious, severe, or extreme depending on the severity of the area's air
quality problem. (See CAA sections 107(d)(1)(C) and 181(a)). The
Baltimore area was designated nonattainment under the 1-hour ozone
NAAQS and classified as severe-15, with an applicable attainment date
of November 15, 2005.
---------------------------------------------------------------------------
\3\ These same counties were designated nonattainment under the
1997 8-hour ozone NAAQS and the 2008 ozone NAAQS. See 40 CFR 81.321
and 77 FR 30088 at 30127, May 21, 2012.
---------------------------------------------------------------------------
On July 18, 1997, (62 FR 38856), EPA promulgated a new, more
protective standard for ozone based on eight-hour average
concentrations (the ``1997 eight-hour ozone NAAQS''). EPA designated
and classified most areas of the country under the eight-hour ozone
NAAQS in an April 30, 2004 final rule (69 FR 23858). In this April 30,
2004 final rule EPA designated the Baltimore area nonattainment under
the 1997 eight-hour ozone NAAQS and classified the area as moderate.\4\
---------------------------------------------------------------------------
\4\ Subsequently, pursuant to section 181(b)(2), EPA
reclassified the Baltimore area as a serious ozone nonattainment
area due to the area's failure to attain 1997 eight-hour ozone NAAQS
on time. See 77 FR 4901, February 1, 2012.
---------------------------------------------------------------------------
On April 30, 2004 (69 FR 23951), EPA also issued a final rule
entitled ``Final Rule To Implement The 8-hour Ozone National Ambient
Air Quality Standard--Phase 1,'' referred to as the Phase 1 Rule. Among
other matters, this rule revoked the 1-hour ozone NAAQS in most areas
of the country, effective June 15, 2005. (See 40 CFR 50.9(b); 69 FR at
23996; and 70 FR 44470 (August 3, 2005)). The Phase 1 Rule also set
forth how anti-backsliding principles will ensure continued progress
toward attainment of the eight-hour ozone NAAQS by identifying which 1-
hour ozone requirements remain applicable in an area after revocation
of the 1-hour ozone NAAQS.
Although EPA revoked the 1-hour ozone standard (effective June 15,
2005), eight-hour ozone nonattainment areas remain subject to certain
1-hour anti-backsliding requirements based on their 1-hour ozone
classification. Initially, EPA's Phase 1 rule to address the transition
from the 1-hour to the eight-hour ozone standard did not include 1-hour
nonattainment area contingency measures or major source penalty fee
programs among the measures retained as 1-hour ozone anti-backsliding
requirements. However, on December 23, 2006, the United States Court of
Appeals for the District of Columbia Circuit determined that EPA should
not have excluded these requirements (and certain others not relevant
here) from its anti-backsliding requirements. South Coast Air Quality
Management District v. EPA,\5\ 472 F.3d 882 (D.C. Cir. 2006), reh'g
denied 489 F.3d 1245 (clarifying that the vacatur was limited to the
issues on which the court granted the petitions for review). Thus, the
Court vacated the provisions that excluded these requirements. As a
result, states must continue to meet the obligations for 1-hour ozone
NAAQS contingency measures. On May 14, 2012 (77 FR 28424), EPA issued a
final rule that, among other things, removed the vacated provisions of
40 CFR 51.905(e) and addressed the anti-backsliding requirement for
contingency measures for failure to attain or make reasonable further
progress toward attainment of the 1-hour ozone standard. See 74 FR
2936, January 16, 2009 (proposed rule); 74 FR 7027, February 12, 2009
(notice of public hearing and extension of comment period); and 77 FR
28424, May 14, 2012. On February 1, 2012, EPA proposed the
determinations that are the subject of this final rulemaking action.\6\
---------------------------------------------------------------------------
\5\ Hereafter this decision will be called ``South Coast.''
\6\ EPA's February 1, 2012 Federal Register NPR was captioned as
potentially affecting 40 CFR parts 52 and 81. Because the final
action does not change the classification or other provisions
relating to the Baltimore area codified in 40 CFR part 81, this
action as finalized results only in revision of 40 CFR part 52.
---------------------------------------------------------------------------
III. What comments were received on these actions and what are EPA's
responses?
We received comments from the Sierra Club, which opposed aspects of
both actions and contended that the proposed rule was incomplete.
Below, EPA summarizes those comments and sets forth EPA's responses.
A. Comments on the Determination of Attainment of the 1-Hour Ozone
NAAQS
Comment 1: The commenter claimed that a finding that Baltimore has
attained since 2008 is premature because monitored data for years since
2008 are for years that are not reflective of the historic trend of
emissions. In support of their position, the commenter cite Draft
Inventory of U.S. Greenhouse Gas Emissions and Sinks, 1990-2010,
(February 2012) to support the proposition that reductions in emissions
of NOX and VOC \7\ in 2008 and 2009 are due in part to
nonpermanent reductions in electricity demand and other emissions
related activities resulting from the economic recession. The commenter
also noted that the same draft inventory stated that CO2
emissions rose by 3.7 percent--the largest increase in a 21 year
period--which should correlate to increasing NOX and VOC
emissions from all sectors as well. The commenter contends that EPA is
required in this rulemaking to further determine that the emissions
decreases were due to pollution controls and not the economic downturn
and cited section 107(d)(3)(E)(iii) of the CAA, which states: ``The
Administrator determines 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.'' The commenter argues that EPA is precluded
here from making a determination of attainment based on monitored air
quality, unless EPA makes an additional analysis and determination that
air quality is due to permanent and enforceable reductions from
enforceable limits and control measures.
---------------------------------------------------------------------------
\7\ NOX is an abbreviation for ``nitrogen oxides;''
VOC is an abbreviation for ``volatile organic compounds.''
---------------------------------------------------------------------------
Response 1: EPA disagrees with the comment. EPA's determination of
attainment in this final rule is properly based on monitored air
quality, and it complies with the statutory and regulatory procedures
that govern the making of a determination of attainment for the
purposes of comparison to the 1-hour NAAQS. See 40 CFR 50.9 and
Appendix H. This determination is by definition solely focused on
monitored air quality concentrations and does not
[[Page 34812]]
involve an assessment of causes for those concentrations. Thus it is
separate and independent of the inquiry into the origins of the reduced
monitored ambient concentrations. The commenter conflates EPA's
obligations when making a determination of attainment, which is based
solely on monitored air quality concentrations, with separate and
additional obligations that apply only when EPA is evaluating a request
to redesignate an area from nonattainment to attainment--a process that
is not being undertaken here. The statutory provision cited by
commenter, section 107(d)(3)(E)(iii) of the CAA, applies only in the
context of a redesignation request, and explicitly lists specific
criteria that must be met for redesignation, which are separate from
and in addition to the criteria that must be met when making a
determination of attainment.
In the quite different context of a redesignation, section
107(d)(3)(E)(iii) of the CAA requires EPA to determine, among other
things, that attainment of a NAAQS resulted from permanent and
enforceable emissions reductions under the applicable SIP and Federal
rules. Section 107(d)(3(E)(i) of the CAA lists a determination of
attainment as an independent factor, separate and apart from the other
criteria for approving a redesignation request. Section
107(d)(3)(E)(iii) of the CAA applies only when EPA proposes to
redesignate an area from nonattainment of a NAAQS to attainment. In our
February 1, 2012 NPR, EPA did not propose to redesignate the Baltimore
area to attainment of the 1-hour ozone NAAQS. Moreover, after
revocation of the 1-hour ozone NAAQS in 2005, EPA no longer
redesignates areas to attainment of the 1-hour ozone NAAQS. Nor as the
commenter claimed, did EPA propose to ``reclassify'' the Baltimore
area.\8\ Instead, the February 1, 2012 NPR proposed only to determine
that the Baltimore area has attained the 1-hour ozone NAAQS based upon
quality-assured and certified data for each consecutive 3-year period
from 2006 to 2008 and through 2008 to 2010. EPA also proposed to
determine that the area continues to attain during the most recent 3-
year period for which data are available, 2009-2011, based upon data
available for 2011. As EPA notes elsewhere in its responses to
comments, these 2011 data have now been certified and quality-assured,
and thus establish that the area continues in attainment for the 1-hour
ozone standard. In accordance with the statute and EPA's regulations,
EPA's determination of attainment is based solely upon monitored air
quality data which establish that the area's air quality has attained
the revoked 1-hour ozone NAAQS. EPA's determination therefore meets
regulatory requirements for the clearly defined purpose for which it is
made. The commenter's concerns and contentions, therefore, are
inaccurate, and do not in any way detract from the sound basis for
EPA's final determination that Baltimore has attained the 1-hour ozone
standard.
---------------------------------------------------------------------------
\8\ After revocation of the 1-hour ozone standard, EPA no longer
reclassifies areas under that standard. Moreover, even prior to
revocation, the statute did not provide for reclassification of
severe areas upon a failure to attain the standard by the applicable
attainment date. See section 181(b)(2).
---------------------------------------------------------------------------
Comment 2: The commenter urges the importance of showing that the
improvement in air quality is not due to the economic downturn is
important because the air quality data indicate that the Baltimore area
is at the upper limit of what can be considered attainment (3.1
expected exceedances over 2009 to 2011) under the 1-hour ozone NAAQS.
The commenter suggests that the air quality improvement and continued
attainment may be due to economic factors and not to pollution controls
and argues that the Baltimore area may quickly slip back into
nonattainment as the economy recovers, and that any ``redesignation of
the area to attainment will not be valid.''
Response 2: EPA disagrees with the comment. As set forth in EPA's
response to Comment 1, as is appropriate, EPA here is making only a
determination of attainment for the 1-hour ozone standard based on
monitored air quality. EPA is not redesignating the area to attainment
for that standard--nor could the Agency do so, in view of the fact that
the 1-hour ozone standard has been revoked since 2005. EPA's clearly
defined determination of attainment here is consistent with the
regulations that apply, and is based upon three years of complete,
quality-assured monitoring data. For each NAAQS, EPA establishes
through regulation procedures for the requisite level (in this case
0.12 ppm \9\), form (averaging periods, etc.) and, minimum data quality
and handling conventions necessary to distinguish compliance from
noncompliance. Although the 1-hour ozone NAAQS as promulgated in 40 CFR
50.9 includes no discussion of specific rounding conventions regarding
rounding measured ambient air quality data or the expected number of
exceedances for a year or over a consecutive three year period, our
publicly articulated position and the approach long since universally
adopted by the air quality management community is that the
interpretation of the 1-hour ozone standard requires rounding ambient
air quality data consistent with the stated level of the standard.
Section 1.0 of Appendix H to 40 CFR part 50 explains how to determine
when the expected number of days per calendar year with maximum hourly
average concentrations above 0.12 ppm is equal to or less than 1.
Section 1.0 of Appendix H refers to ``Guideline for Interpretation of
Ozone Air Quality Standards'' \10\ for an ``expanded discussion of
these procedures and associated examples.'' In section 2.1--
Interpretation of Expected Number, this ``Guideline for Interpretation
of Ozone Air Quality Standards'' says as long as ``this arithmetic
average remains `less than or equal to 1' the area is in compliance. As
far as rounding conventions are concerned, it suffices to carry one
decimal place when computing the average.'' In the 1990 amendments to
the CAA, Congress expressly recognized the continuing validity of EPA
guidance. See generally, H Comm. Rep. 101-490 pp. 197, 232 (1990)
(House Energy and Commerce Committee Report). Under EPA regulations, a
sum of 3.1 expected exceedances over a consecutive 3-year period
complies with the standard because the average is 3.1 divided by 3 or
1.0333 * * * that when rounded to carry one decimal place is 1.0 which
does not exceed 1. The fractional value of the amount of expected
exceedances arises due to missed monitoring days and derives from
calculations pursuant to Appendix H to 40 CFR part 50. The form of the
standard itself in terms of average number of ``expected exceedances''
is grounded in statistical considerations because the term ``expected
exceedances'' is a statistical term. See section 2.0 of ``Guideline for
Interpretation of Ozone Air Quality Standards.'' This fractional part
of ``expected exceedances'' for a year or for a consecutive 3-year
period arises from the calculation required using the procedures of
Appendix H to 40 CFR part 50 to account for the number of days for
which no valid data difference between the required number of required
monitoring days in the year and the actual number of days with valid
data with an allowance for the number of days a state may assume to
[[Page 34813]]
be less than the standard level. These calculations were provided in
Appendix A to ``Technical Support Document--Determination of Failure to
Attain by 2005 and Determination of Attainment by 2008 for the 1-Hour
Ozone National Ambient Air Quality Standards in the Baltimore
Nonattainment Area in Maryland.\11\'' Thus, the form of the 1-hour
ozone NAAQS restricts the level of uncertainty, in the form of missed
monitoring data as expressed, in the case of the 2011 data for one
monitor, as 3.1 expected exceedances over a three-year period.

---------------------------------------------------------------------------
This fractional number is not an indication that the area is not
attaining the standard, but rather takes into consideration and
accounts for missing data. Moreover, EPA determines whether the area is
in attainment through the procedures and definitions supplied in the
regulations and under long standing interpretations. EPA does not
distinguish degrees of attainment. Once an area's monitored
concentrations show that it is below the level of concentrations
defined as ``attainment'' of the standard, EPA considers the area to be
in attainment of that standard.
Comment 3: The comments assert that EPA cannot determine that the
Baltimore area is attaining the 1-hour ozone NAAQS for the period 2009
to 2011 unless and until EPA has determined the 2011 data meet the data
quality standards of 40 CFR 50.9 and Appendix H for use in compliance
determinations. The commenter stated that the data for 2011 reflect 209
out of 214 required monitoring days, with ``three days assumed less
than the standard,'' and contends that EPA must show that the missing
days are not contributing to nonattainment for 2009-2011, according to
the applicable calculation methods.
Response 3: EPA agrees that a determination of attainment of the
revoked 1-hour ozone standard should be consistent with relevant
regulatory requirements. EPA has determined that the 2011 data meet the
quality assurance and certification requirements for use to determine
compliance with the 1-hour ozone NAAQS through 2011. In making a
determination of attainment, EPA relies on the most recent three years
of complete, quality-assured data, and also reviews subsequent data
that become available and that suggest consistency with continued
attainment. On February 1, 2012 (77 FR 4940), EPA proposed a
determination that the Baltimore area has attained the 1-hour ozone
NAAQS, and included data showing that the area had attained the
standard since 2008. Although at that point the 2011 data had not yet
been certified by the State of Maryland, the data for prior years had
been previously certified and showed continuous attainment, and
available data for 2011 were consistent with continued attainment. On
April 12, 2012, the Maryland Department of the Environment certified
the 2011 air quality monitoring data for ozone as complete and quality-
assured. EPA has reviewed the certified 2011 1-hour ozone monitoring
data and determined that the certified 2011 data matches and is the
same as that used to support the February 1, 2012 NPR. Because data for
2011 have now have been certified as complete and quality-assured, this
final rule determining that the Baltimore area is attaining the 1-hour
ozone NAAQS is based upon the most recent three years of complete,
quality-assured, certified air quality monitoring data for 2009 to
2011. As discussed in the previous response, the form of the 1-hour
ozone NAAQS and Appendix H to 40 CFR part 50 (which contains the
interpretation and procedures to calculate the number of expected
exceedances for a year) account for any days for which valid data are
missing. For this reason, EPA can determine the Baltimore area is
attaining the 1-hour ozone NAAQS now that the 2011 data have been
certified.
Comment 4: The comments asserted that the 2008 1-hour ozone data
for the Edgewood monitor is missing as evinced by an Ozone Monitor
Report 2008 obtained from EPA's Web page http://www.epa.gov/airdata/ad_rep_mon.html. Thus, the comments assert EPA needs to provide these
data and verify that there actually were no values at the Edgewood
monitor in 2008 above the 125 ppb level, and EPA needs to explain why
the 2008 1-hour data for Edgewood, which is the critical monitoring
data for determining attainment, is missing from its Web page. The
comments expressed concern that the 8-hour averages are also very high
which suggests that there may have been 1-hour levels above 125 ppb.
Response 4: In response to this comment, EPA re-checked the 2008 1-
hour ozone monitoring data for the Edgewood monitor (AQS ID number 24-
025-1001). Although the 2008 data were complete and available through
the portal EPA uses to access AQS, EPA learned that the data for 2008
had not been completely available through the public portal access. The
2008 1-hour ozone air quality data were and are recorded in EPA's Air
Quality Data (AQS) system, which is EPA's official repository for air
quality data to be used for determinations of compliance with a NAAQS.
In preparation for the February 1, 2012 NPR, on March 3, 2011, EPA
viewed and retrieved the data in AQS for the 2008 (as well as the 2004
through 2007, and 2009 through 2010 years) ozone air quality data, and
used this data in the compliance calculations for the proposed
rule.\12\ These calculations were provided in the Technical Support
Document (TSD)--``Determination of Failure to Attain by 2005 and
Determination of Attainment by 2008 for the 1-Hour Ozone National
Ambient Air Quality Standards in the Baltimore Nonattainment Area in
Maryland,'' dated January 26, 2012'' for the proposed rule. See docket
item EPA-R03-OAR-2011-0680-0008.\13\ After receiving the Sierra Club's
comment on this issue, EPA re-checked and downloaded a ``Monitor values
Report'' dated April 16, 2012, for the same 2008 data for the Edgewood
monitoring site via the public access portal of ``Air Data Mart.'' \14\
From an examination of this April 16, 2012 ``Monitor Values Report,''
EPA learned that all the data for the ozone monitors in Harford County
could not be accessed through that portal and that in fact the 2008
data were in AQS. The April 16, 2012 ``Monitor Values Report''
indicated that there were 4850 ``observations'' (data points) in AQS
for the Edgewood monitoring site which equals the same number of
observations as for the 202 valid days of monitoring data for the
Edgewood monitor in 2008 used in the compliance calculations prepared
for the February 1, 2012 NPR.15 16 Upon investigation EPA
determined that there was a minor fault in the Air Data Mart public
access portal system and has corrected the problem. EPA has verified
that the complete 2008 data can now be accessed via the ``Air Data
Mart.'' On May 1, 2012, EPA retrieved a copy from the ``Air Data Mart''
and placed a copy of the output which displays the 2008
[[Page 34814]]
data in the docket for this action.\17\ EPA has verified that the 2008
data for the Edgewood monitor now available through the ``Air Data
Mart'' portal do not affect its determination of attainment for the
area during any period that included 2008 data because the data
available on May 1, 2012 via the ``Air Data Mart'' portal is the same
as that EPA obtained on March 3, 2011 for use in the compliance
calculations prepared for the February 1, 2012 NPR. These data values
were thus considered by EPA and do not affect EPA's determinations for
any attainment period that included the 2008 data. Moreover, EPA has
also determined here that the area is attaining the standard for the
most recent three years of complete, quality-assured data, 2009-2011.
EPA's determination for this most recent period does not include or
require reliance upon any data for 2008.
---------------------------------------------------------------------------
\12\ There are several levels of access to AQS such as the
public access portal ``http://www.epa.gov/airdata/ad_rep_mon.html'' and various restricted access portals used by States and

restricted access portal to obtain the 2008 data presented in the

---------------------------------------------------------------------------
EPA recognizes that, for the 1997 ozone NAAQS, the 8-hour ozone
values in the Baltimore area exceed that NAAQS, and EPA has taken
action accordingly:
1. On February 1, 2012, EPA determined that the Baltimore 1997 8-
hour moderate ozone nonattainment area had failed to attain the 1997 8-
hour NAAQS by its applicable attainment date, and the Baltimore area
was reclassified as a serious ozone nonattainment area.\18\ See 77 FR
4901, February 1, 2012.
---------------------------------------------------------------------------
\18\ The boundaries of the ``Baltimore'' nonattainment areas are
the same under both the 1-hour and 1997 8-hour (40 CFF 50.10) NAAQS.
---------------------------------------------------------------------------
2. On April 30, 2012, the EPA Administrator signed a final rule
that designated areas as nonattainment or attainment for 2008 ozone
NAAQS, which is codified at 40 CFR 50.15. The Baltimore, MD area was
included as a nonattainment area. See 77 FR 30088 at 30127, May 21,
2012.
B. Comments Concerning Effect of Determination of Baltimore Area's
Failure to Attain the 1-Hour Ozone NAAQS
Comment 1: The comments express support for EPA's statement that
the Baltimore area's failure to attain by its statutory 1-hour
attainment date of November 15, 2005 bears on obligations with respect
to two 1-hour ozone anti-backsliding requirements whose implementation
would be triggered by a finding of failure to attain: contingency
measures for failure to attain and section 185 major stationary source
fee programs. However, the commenter disagrees with the proposed rule's
discussion of the effect of the determination on these 1-hour ozone
anti-backsliding requirements. Specifically, the commenter criticizes
EPA's statements below:
1. ``If this determination [of current 1-hour attainment of ozone
NAAQS] is finalized, then even if EPA finalizes its proposed
determination that the area failed to attain the 1-hour ozone standard
by the 2005 deadline, it will not result in any 1-hour ozone
contingency measure obligations for the area.'' See 77 FR 4940 at 4943.
2. ``A final determination of failure to attain by the area's 1-
hour attainment date would trigger the 1-hour anti-backsliding
obligation to implement the penalty fee program under section[s]
182(d)(3)[,] 182(f) and 185, unless that obligation is terminated.''
See 77 FR 4940 at 4943.
The comments assert that under the South Coast decision EPA is
obligated to enforce contingency and fee measures in areas that fail to
attain the 1-hour ozone NAAQS by their attainment dates and is not
authorized to release the area from its contingency obligations or to
terminate the obligation to pay the section 185 and other fees
With respect to the section 185 fee requirement, the commenter
states that the Baltimore area failed to attain by November 15, 2005,
and that the Baltimore area did not receive an extension of its
attainment date (section 181 (a)(5) of the CAA). The commenter contends
that therefore the area is subject to 185 fees on its major sources of
VOCs and NOx for the time period 2005-2008.
Response 1: First, we wish to emphasize, as EPA stated in its
proposal, that the purpose of this rulemaking notice is to make
specific air quality determinations regarding whether the Baltimore
area attained the revoked 1-hour ozone standard. While EPA's proposal
stated that these determinations bear on 1-hour anti-backsliding
requirements for contingency measures and CAA section 185 penalty fees,
this notice does not attempt to address or resolve all the
implementation issues regarding those requirements. Thus, Sierra Club's
position that EPA's specific rulemakings on air quality determinations
must also include resolutions of all anti-backsliding implementation
issues that may flow from them is incorrect. While EPA recognizes that
the anti-backsliding requirements for 1-hour ozone contingency measures
and section 185 fees are linked to the determination of failure to meet
the attainment deadline for that standard, EPA's rulemakings here
regarding those determinations do not, and are not required to, dispose
of all implementation issues for those requirements or for others, such
as those raised in Sierra Club's comments regarding milestones and
additional planning.
Nevertheless, EPA sets forth below its views on points raised by
the commenter. First, with respect to contingency measures, EPA
believes that, as EPA explains in its response below in the context of
the requirement for section 185 penalty fees, it is EPA's final
determination that the area failed to attain by its attainment date
that triggers the requirement to implement these. Since EPA is also
finalizing here its determination that the area is currently attaining
the 1-hour ozone standard, the obligation to submit or implement any
measures is suspended. This would be the case, moreover, even if the
obligation for contingency measures had been triggered at an earlier
date because the purpose of nonattainment contingency measures for
failure to attain is to provide for progress towards attainment. Once
attainment has been reached, this purpose is satisfied. EPA's Clean
Data Policy and the many Courts which have upheld it, including
National Resources Defense Council v. EPA, 571 F.3d 1249 (D.C. Cir.
2009), support this rationale.\19\ Contrary to commenter's complaint,
EPA is not here unlawfully refusing to effectuate the anti-backsliding
requirement for contingency measures. Nor is EPA unlawfully releasing
the area from its anti-backsliding obligation with respect to
contingency measures. To the contrary, EPA is following the long-
established legal path to determining that the contingency measure
requirement has been satisfied by a determination, after notice-and-
comment rulemaking, of attainment of the 1-hour ozone standard. In
making the determination that the area failed to attain the 1-hour
ozone standard by its applicable attainment date, and concurrently
making the determination that the area has been attaining the 1-hour
ozone standard since 2008, and that it continues to attain that
standard, EPA is enforcing the anti-backsliding requirement. The
Baltimore area is not backsliding on the 1-hour ozone standard; as EPA
has determined, the Baltimore area has attained that standard, and
continues to attain it.
---------------------------------------------------------------------------
\19\ See also 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). See the additional cases listed in footnote 7
of the February 1, 2012 NPR (77 FR 4940 at 4943).
---------------------------------------------------------------------------
[[Page 34815]]
EPA also points out that in these circumstances EPA is not required
to show the causes or amounts of the reductions that have brought the
area into attainment over the last years. EPA's discussion of the
contributions that the 1997 ozone controls have made to 1-hour ozone
attainment was aimed at showing that 1-hour attainment has occurred in
the context of ongoing reductions for a more stringent ozone standard.
This showing is not necessary to and is not relied upon in EPA's
determination that the obligation to submit 1-hour ozone contingency
measures has been satisfied.
In its comments, Sierra Club argues that EPA's determination that
the Baltimore area failed to attain by its 1-hour ozone attainment
deadline also requires EPA to decide here that it must retroactively
collect penalties under section 185 for the period before EPA made its
determination.\20\ We disagree. Neither EPA's determination, nor the
South Coast case, compels EPA to reach this conclusion or even to
decide that issue here. EPA intends to address issues regarding 1-hour
anti-backsliding requirements in future rulemakings on implementation
of the section 185 requirements for the Baltimore area. Nevertheless,
we wish to express our preliminary views on Sierra Club's comments
below. EPA's preliminary views, as set forth below, are not necessary
to and are independent of its air quality determinations regarding
nonattainment and attainment that are contained in this notice of final
rulemaking.
---------------------------------------------------------------------------
\20\ As explained above and elsewhere in our response to
comments, EPA disagrees with Sierra Club's contentions regarding
retroactive collection of fees. As a technical point, however, we
note that under section 185, the earliest year for which fees could
ever have been required to be paid is the calendar year following
the attainment date, November 15, 2005. Thus, it is clear that under
no circumstances would fees be due for 2005.
---------------------------------------------------------------------------
Sierra Club's comments quote at length from South Coast, 472 F.3d
at 902-903. While EPA acknowledges that this decision established that
section 185 fee requirements were to be included as anti-backsliding
measures, the Court in that case did not direct any specific means of
enforcement of these requirements, nor the method for determining
whether an area failed to attain by its attainment date. That decision
established only that the section 185 and contingency measure
requirements were ``applicable.'' It did not establish or even address
how those requirements were to be implemented.\21\
---------------------------------------------------------------------------
\21\ Moreover, as EPA explained above, those issues are
ancillary to the determination of failure to attain the 1-hour ozone
standard that EPA is finalizing in this rulemaking.
---------------------------------------------------------------------------
The D.C. Circuit, however, has previously upheld EPA's longstanding
practice of making determinations of an area's failure to meet
attainment deadlines solely through notice and comment rulemaking. See
Sierra Club v. Whitman, 285 F.3d 63 (D.C. Cir. 2002). In that case,
which similarly arose from a determination of failure of a 1-hour ozone
nonattainment area to meet its attainment deadline, the D.C. Circuit
rejected a litigant's \22\ demand to make the consequences of that
determination retroactive to the time period before EPA made the
determination. See Sierra Club v. Whitman, 285 F.3d 63 (D.C. Cir.
2002).\23\ In that case, Sierra Club similarly argued that EPA's
overdue determination that the St. Louis 1-hour ozone nonattainment
area failed to attain by its attainment deadline should apply
retroactively, and that the Court should require retroactive
reclassification of the area. The Court rejected Sierra Club's
contention that an EPA rulemaking was not required to determine a
failure to attain.
---------------------------------------------------------------------------
\22\ In that case, also Sierra Club.
\23\ Sierra Club v. Whitman was discussed and distinguished in a
recent D.C. Circuit decision that addressed retroactivity in a quite
different context, where, unlike here, EPA sought to give its
regulations retroactive effect. National Petrochemical and Refiners
Ass'n v. EPA. 630 F.3d 145, 163 (D.C. Cir. 2010), rehearing denied
643 F.3d 958 (D.C. Cir. 2011), cert denied 132 S. Ct. 571 (2011).
---------------------------------------------------------------------------
``No matter what the Sierra Club thinks the Clean Air Act or the
APA required of EPA, the fact remains that `EPA's established practice
for making a final decision concerning nonattainment and
reclassification is to conduct a rulemaking under the APA, not to issue
a letter, a list, or some other informal document.' * * * [citations
omitted.]'' The Court concluded: ``In other words, if there has not
been a rulemaking there has not been an attainment determination.'' 285
F.3d at 66.
The Court also refused to accept Sierra Club's assertion that the
Court should compel EPA to give retroactive effect to its
determination, resulting in reclassification as of the area's
attainment date. The Court stated: ``Although EPA failed to make the
nonattainment determination within the statutory time frame, Sierra
Club's proposed solution only makes the situation worse. Retroactive
relief would likely impose large costs on the states, which would face
fines and suits for not implementing air pollution prevention plans
[earlier], even though they were not on notice at the time.'' 285 F.3d
at 68.
While it is true that the Clean Air Act provides that both
reclassification and penalty fees are consequences of failure to attain
the ozone standard, the D.C. Circuit in Sierra Club recognized that
these weighty consequences are not triggered until EPA makes a
determination, after notice and comment rulemaking, of failure to
attain. In that case, the Court also rejected the view that adverse
consequences from the determination should be imposed retroactively,
especially if it would, as here, subject the states to additional
burdens caused by retroactive requirements that they were not given
notice of prior to conclusion of the rulemaking process.
Several features of our rulemaking for Baltimore provide additional
grounds for application of a similar position to that taken by the
court in the St. Louis Sierra Club case. In the case of St. Louis, when
the question of retroactive application arose, the area remained in
nonattainment of the 1-hour ozone standard, which was also still the
only standard in effect at the time of the Court's decision. Here,
unlike St. Louis, EPA has determined that the Baltimore area is
currently attaining the 1-hour ozone standard, and thus there is
significantly less reason to consider imposing retroactive penalties
that are intended to bring about the attainment that has already
occurred.
Sierra Club here argues, unpersuasively, that the South Coast
opinion supports retroactive imposition of penalties, quoting the
Court's statement that, unless section 185 requirements were
applicable, '' a state could go unpenalized without ever attaining even
the original NAAQS. * * *'' 472 F.3d at 903. Here, however, this
possibility does not exist. EPA's final determination in this
rulemaking establishes that the Baltimore area has in fact attained the
1-hour ozone standard.
Sierra Club quotes the Court's statement in South Coast that
``Congress set the penalty deadline well into the future, giving states
and industry ample notice and sufficient incentives to avoid the
penalties.'' 372 F.3d at 903. Notice of the existence of penalty
provisions, however, is not the same as notice that these provisions
have been triggered. As the D.C. Circuit recognized in Sierra Club v.
Whitman, only when EPA issues a final notice determining that an area
has failed to attain by the attainment date can that failure be
definitively established. The case of Baltimore presents a particularly
compelling context in which to apply this principle. The Baltimore area
has been attaining the 1-hour ozone standard since 2008. No
incentives--and certainly no penalties--are required for the area to
[[Page 34816]]
reach attainment,\24\ a goal that the area has met and preserved. Under
these circumstances, and based on the D.C. Circuit's and EPA's long
held position on the issue of retroactive consequences of
determinations of failure to attain, EPA cannot see a reason to impose
penalties on sources in Baltimore. As explained above, EPA is
determining that the area is currently, and has for some time been,
attaining the 1-hour ozone standard. Thus no anti-backsliding purpose
is served by retroactive imposition of fees for a failure to meet a
deadline for a revoked standard, under circumstances that existed years
ago, which have since been eclipsed by continuous attainment. EPA
believes that forcing the states and sources to address old penalties
now would also divert attention and resources from efforts to achieve
current, forward-looking environmental goals, including the stricter
2008 ozone standard. In these circumstances, giving retroactive effect
to EPA's determination of failure to attain the standard here would be
unreasonable, and it would, as the Court held in Sierra Club v.
Whitman, ``only mak[e] the situation worse.''
---------------------------------------------------------------------------
\24\ Sierra Club appears to recognize this, since it does not
request EPA to impose penalties for the time period after the area
attained the standard (2010 to the present).
---------------------------------------------------------------------------
Comment 2: The commenter asserts under South Coast (at 903-904)
that, ``anti-backsliding'' considerations require that 1-hour
contingency measures must remain in place even after transitioning away
from the 1-hour ozone standard. The commenter asserts that because EPA
has not yet approved contingency measures for failure to attain for the
Baltimore area, EPA must take remedial action either under 42 U.S.C.
7410(k)(5) to issue a call for a plan revision for the required
contingency measures or under 42 U.S.C. 7410(k)(6) to correct its final
action on the SIP for the Baltimore area by disapproving the submission
\25\ for lack of the contingency measures. The comments assert that EPA
must issue a Federal Implementation Plan (FIP) that includes the
required contingency measures.
---------------------------------------------------------------------------
\25\ The comments used the phrase ``disapprove the submit.''
---------------------------------------------------------------------------
Response 2: Even if there existed any outstanding SIP submission
requirement for contingency measures for failing to meet the deadline
to attain the revoked 1-hour ozone standard, EPA's final determination
here that the area has attained the 1-hour ozone standard suspends that
requirement. Pursuant to EPA's Clean Data Policy, EPA's determination
that the area has attained the 1-hour ozone standard means that
attainment has been reached, and thus the purpose of the contingency
measures is fulfilled.
Comment 3: The commenters claim that any contingency measures now
needed must be from ``current emissions'' and that crediting reductions
from measures in the reasonable further progress (RFP) for 2008 under
the 1997 ozone NAAQS is not supported by any statutory authority. In
addition, the commenters claim that use of the RFP reductions in the
RFP plan for 2008 is arbitrary for two reasons:
The commenters claim that the 2008 RFP plan does not provide enough
reductions of VOC emissions and that EPA cannot rely on substituting
NOx reductions because there is no direct NOx to VOC trade-off. The
comments assert that the 1-hour contingency requirement is 13.77 tons
per day (tpd) of VOC reductions whereas the RFP plan required 2.05 tpd
of VOC reductions to leave a shortfall of 11.72 tpd of VOC reductions.
The comments claim the contingency plan cannot rely on the ``1997''
ozone NAAQS \26\ requiring more NOX reductions than the 1-
hour contingency requirement ``because there is no such thing as a
direct NOx to VOCs trade off'' and that ozone formation is more
complicated than that. The comments further contend because EPA has not
demonstrated that the RFP reductions have been achieved EPA cannot
credit them towards the contingency requirement.
---------------------------------------------------------------------------
\26\ See 40 CFR 50.10.
---------------------------------------------------------------------------
Response 3: EPA disagrees with this comment. EPA believes that
EPA's determination that the Baltimore area attained the 1-hour ozone
NAAQS in 2008 and has continued to attain this NAAQS suspends the
requirement for submission of 1-hour ozone contingency measures. EPA's
final determination of attainment for the 1-hour ozone standard removes
the need at this time to further address any comments or objections
related to the contingency measure requirement. EPA's determination
that the area has been attaining the 1-hour ozone standard since 2008,
and continues to attain the standard, provides independent and
sufficient grounds for concluding that the 1-hour contingency measure
anti-backsliding requirement is satisfied. No additional reductions
from contingency measures--or any other measures--are needed to bring
about attainment of the 1-hour ozone standard or reasonable progress
toward that attainment, which has already been achieved.
Thus it is not necessary for the purpose of finalizing this notice
to address the commenter's critique of EPA's discussion, in its
proposed rulemaking, of emissions reductions that may have contributed
to attainment. In the February 1, 2012 NPR, EPA included a discussion
of emissions reductions that had occurred in Baltimore in the period
after the area's 1-hour ozone attainment deadline. EPA's discussion
described certain emissions reductions that served the same function as
contingency measures would have done, whether or not the measures that
brought about those reductions had formally been approved as
contingency measures. The commenter addresses EPA's discussion and
criticizes its analysis of post-2005 reductions. While EPA disagrees
with the commenter's views of these reductions, and believes that they
reflect a misunderstanding of the CAA requirements, EPA finds it
unnecessary to respond specifically to them in this rulemaking. The
purpose of contingency measures is to bring about attainment, and EPA's
determination that the area has attained the 1-hour ozone standard
shows that this purpose has been achieved. In these circumstances, it
is not necessary to reach agreement on calculations regarding the
emissions reductions that brought the area into attainment. Attainment
of the 1-hour ozone standard has been reached, and thus no contingency
measures are required to reach attainment. This is all the more true
for an area subject to ongoing implementation of additional control
measures for the 1997 8-hour ozone standard. The decision of the DC
Circuit in South Coast did not address or invalidate the Clean Data
Policy, which was upheld by that Circuit in Natural Resources Defense
Council v. EPA.
Comment 4: The commenter claims that the contingency measures
should have come into place in 2005 when the area was violating, and,
therefore, EPA cannot use the Clean Data Policy to suspend the
requirement because, the commenter argues: (1) The FIP clock should
have long since passed and a clean data determination cannot excuse EPA
from its FIP obligation; (2) to use the Clean Data Policy would
effectively remove the contingency measure requirement and create a
backslide by removing a requirement that should have been in place
before the clean data determination. The commenter claims that the
Court in South Coast precludes EPA from removing requirements that
[[Page 34817]]
were required before this clean data determination.\27\
---------------------------------------------------------------------------
\27\ The comments contend that the Baltimore area is still
experiencing ``exceedances'' of the 1-hour ozone NAAQS. An
exceedance of the standard does not constitute a violation of that
standard. EPA responses elsewhere in this document show that the 1-
hour ozone NAAQS defines an area as attaining the standard if it has
fewer than or equal to 3.1 expected exceedances over any consecutive
3-year period. As EPA has shown, for the past four years, since
2008, the Baltimore area has not monitored a violation of the 1-hour
ozone NAAQS.
---------------------------------------------------------------------------
Response 4: As set forth in EPA's response to comments above, prior
to this final rulemaking EPA had not determined that the area failed to
attain by its attainment deadline, and thus, contrary to the
commenter's contention, no contingency measures for failure to attain
had been triggered. See Sierra Club v. Whitman, cited above in EPA's
Response to Comment. Moreover, as explained elsewhere in this notice
and in EPA's proposed rulemaking, EPA is also making here a final
determination that the area has attained the 1-hour ozone standard.
This determination establishes that the purpose of the contingency
measures has been fulfilled. This is the case even if it is determined
that the area previously failed to attain by the applicable deadline. A
determination that the area has attained and continues to attain the
standard, whenever it is issued, logically means that no contingency
measures need be adopted to reach attainment. Thus there is no legal or
common sense justification for a retroactive imposition of ozone
contingency measures intended to achieve attainment of the revoked 1-
hour ozone standard, a goal that has already been reached.
EPA's prior rulemakings demonstrate that its interpretation under
the Clean Data Policy applies after revocation of the 1-hour ozone
standard, and after the South Coast decision (See 74 FR 13166 (March
26, 2009) and 75 FR 6570 (February 10, 2010). Moreover, since there was
and is no state obligation to adopt one- hour contingency measures,
there is no FIP obligation. Because no SIP deficiency exists with
respect to 1-hour ozone contingency measures, no FIP requirement based
upon it exists either. Contrary to commenter's claim, EPA's
interpretation under the Clean Data Policy does not act to remove an
anti-backsliding requirement; rather, as the Courts have held, even
when the 1-hour ozone standard was in effect, it is an interpretation
that the requirement is satisfied by attainment. Sierra Club v. EPA
(10th Cir. 1996). Contingency measures have no meaning while an area is
attainment.
C. Comments Concerning Revised State Implementation Plan for 1-Hour
Ozone
Comment 1: The commenter asserts that section 182 of the CAA
requires EPA to require Maryland to submit a ``revised SIP'' for ozone
for the Baltimore area. To support this proposition, the commenter
cites the opening paragraph of section 182(d).\28\ The commenter states
that the plans required by sections 182(c) and (d) of the CAA include
but are not limited to ``enhanced monitoring, attainment and reasonable
further progress \29\ demonstrations, NOx control, and contingency
provisions, as well as the enforcement of fees under ``section
182(d)(3)'' (that is the section 185 fees).
---------------------------------------------------------------------------
\28\ This paragraph states: ``Each State in which all or part of
a Severe Area is located shall, with respect to the Severe Area,
make the submissions described under subsection (c) [i.e., section
182(c)] of this section (relating to Serious Areas), and shall also
submit the revisions to the applicable implementation plan
(including the plan items) described under this subsection [section
182(d)].'' (with clarifying citations added)
\29\ ``RFP'' hereafter.
---------------------------------------------------------------------------
Response 1: EPA disagrees that Maryland must submit additional SIP
revisions for attainment and reasonable further progress
demonstrations, NOx control, and contingency provisions as a
consequence of EPA's determination that the Baltimore area failed to
attain the revoked 1-hour ozone standard by November 15, 2005. EPA does
not agree with commenter's view regarding requirements for a severe
nonattainment area that fails to meet its attainment deadline to revise
its SIP to provide for additional RFP demonstrations and contingency
measures under CAA section 182. Nor does EPA believe that section
181(b)(4) of the CAA imposes any requirements for the revoked 1-hour
ozone standard, because no further 1-hour ozone planning requirements
under that provision or any other, applicable to an area such as
Baltimore, were preserved in anti-backsliding.
After a standard has been revoked, there is no requirement to
revise an initial attainment demonstration for a severe area after the
area fails to attain by the statutorily applicable attainment date.\30\
We disagree with the commenter's claim that EPA's determination here
triggers the Baltimore area's obligations to adopt and submit a broad
variety of additional SIP revisions for the revoked 1-hour ozone
standard. A plan revision under section 181(b)(4) of the CAA is not an
applicable anti-backsliding requirement under EPA's anti-backsliding
regulations. As EPA has explained in other rulemakings, only those
anti-backsliding requirements that were specifically retained by the
anti-backsliding rule, 40 CFR 51.905, and by the decision in South
Coast are applicable, and others cited by the commenter are not
included. See 76 FR 82133 at 82139-140 (December 30, 2011). As EPA
stated in its proposal, the only anti-backsliding measures that pertain
to this determination of failure to meet the 1-hour deadline are 1-hour
contingency measures for failure to attain and section 185 penalty
fees.
---------------------------------------------------------------------------
\30\ As noted in the February 1, 2012 NPR, EPA has fully
approved into the Maryland SIP a 1-hour ozone attainment
demonstration, reasonably available control measures and reasonable
further progress (RFP) plans, and RFP contingency measures for the
Baltimore area. See 77 FR 4940 at 4942-4943, February 1, 2012.
---------------------------------------------------------------------------
Moreover, as set forth above, under EPA's Clean Data Policy, EPA's
determination that the area is currently attaining the 1-hour ozone
standard obviates the need for submission of any planning requirements
related to attainment of the standard. Section 181(b)(4) of the CAA,
cited by the commenter, was not preserved as an anti-backsliding
requirement for the 1-hour ozone standard. In the February 1, 2012 NPR,
EPA stated that its determination ``relates [solely] to effectuating
the anti-backsliding requirements that are specifically retained.'' See
77 FR 4940 at 4942, February 1, 2012.
Comment 2: The comments state that if EPA maintains that the
Baltimore area has attained the 1-hour ozone standard, EPA must require
a new SIP under ``42 U.S.C. Sec. 7505s(a)'' \31\ which would provide
for ``the maintenance of the national primary ambient air quality
standard for such area in the area concerned for at least 10 years
after the redesignation.''
---------------------------------------------------------------------------
\31\ Based upon context, EPA concludes the citation to Sec.
7505s(a) in the comment letter is a scrivener's error and should be
to 42 U.S.C. section 7505a(a) (section 175A(a)).
---------------------------------------------------------------------------
Response 2: EPA disagrees with the comment for several reasons.
Section 175A of the CAA requires that a state submit a ``maintenance
plan \32\'' for the area for which redesignation to attainment is
sought.
---------------------------------------------------------------------------
\32\ A maintenance plan is a SIP revision to provide for
maintenance of the NAAQS in question for a period of ten years after
the area is redesignated to attainment. See, 42 U.S.C. 7505a(a).
---------------------------------------------------------------------------
Section 175A of the CAA applies in conjunction with a state's
request to redesignate an area from nonattainment to attainment
pursuant to section 107(d)(3) of the CAA. The maintenance plan referred
to takes effect after EPA approves the area's redesignation to
attainment. Until a state submits such a request for redesignation of a
nonattainment area, section 175A by its
[[Page 34818]]
own terms does not require submission of any SIP revision.
Section 175A(a) of the CAA provides that each state which submits a
request for redesignation of an area to attainment ``shall also
submit'' a maintenance plan under section 175A of the CAA. In context
``shall also submit'' means that the state must submit a maintenance
plan under section 175A only when it requests redesignation under
section 107(d)(3)(E) of the CAA. Thus section 175A compels submission
of a maintenance plan if and only if the state submits a request for
redesignation of a nonattainment area to attainment. Sections
107(d)(3)(E) and 175A of the CAA do not require submission of a request
to redesignate an area to attainment, nor do they require submission of
a maintenance plan in the absence of a redesignation request. As set
forth in EPA's responses above, EPA no longer redesignates areas for
the revoked 1-hour ozone standard.
EPA no longer redesignates areas to attainment of the 1-hour ozone
NAAQS because EPA revoked that NAAQS on June 15, 2005, as a result of
implementation of the more protective 1997 ozone NAAQS. EPA notes that
the Baltimore area is designated as serious nonattainment for the 1997
ozone NAAQS and has been designated classified as moderate
nonattainment for the 2008 ozone NAAQS.\33\ For all the reasons set
forth above, no requirement for a 1-hour ozone maintenance plan under
section 175A of the CAA is applicable to the Baltimore area.
---------------------------------------------------------------------------
\33\ Subsequent to June 15, 2005, EPA has issued a revised ozone
NAAQS (the 2008 ozone NAAQS codified at 40 CFR 50.15) for which the
level of the standard, 0.075 ppm--lower than the 0.08 ppm of the
1997 ozone NAAQS. A May 21, 2012 (77 FR 30088 at 30127) final rule
designated and classified the Baltimore area as moderate
nonattainment under the 2008 ozone NAAQS.
---------------------------------------------------------------------------
IV. Final Actions
EPA is making two separate and independent determinations related
to the Baltimore 1-hour ozone nonattainment area. These determinations
are based upon complete, quality-assured and certified ozone monitoring
data.
A. Determination of Failure To Attain the 1-Hour Ozone NAAQS by the
Applicable Attainment Date
With respect to the 1-hour ozone standard, and pursuant to EPA's
authority to ensure implementation of 1-hour ozone anti-backsliding
requirements and under CAA section 301, EPA is determining that data
for 2003-2005 show that the Baltimore area previously failed to attain
the 1-hour ozone standard by its applicable November 15, 2005
attainment deadline.
B. Determination of Current Attainment of the 1-Hour Ozone NAAQS
EPA is determining that the Baltimore area is currently attaining
the 1-hour ozone standard. EPA's determination is based on the most
recent three years of complete, quality-assured and certified data for
2009-2011. In addition complete, quality assured and certified data
show that the Baltimore area has attained since the 2006-2008
monitoring period and for every three-year period since that time.
Pursuant to EPA's interpretation, as set forth in its Clean Data Policy
and the cases and regulations that embody it, EPA has determined that
the Baltimore area is no longer obligated to submit and implement the
1-hour ozone contingency measure requirement of CAA section 172(c)(9).
V. Statutory and Executive Order Reviews
A. General Requirements
This action makes determinations of attainment and nonattainment
based on monitored air quality data and does not impose additional
requirements beyond those imposed by statute or regulation. For that
reason, this action:
Is not ``significant regulatory actions'' 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 economically significant regulatory actions based
on health or safety risks subject to Executive Order 13045 (62 FR
19885, April 23, 1997);
Is not significant regulatory actions 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, 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, these final actions regarding attainment of
the 1-hour ozone NAAQS in the Baltimore area do 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.
B. Submission to Congress and the Comptroller General
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).
C. Petitions for Judicial Review
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 August 13, 2012. 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 regarding determinations concerning attainment of
the 1-hour ozone NAAQS in the Baltimore area may not be challenged
later in proceedings to enforce its requirements. (See section
307(b)(2).)
