Determinations of Attainment by the Attainment Date, Extensions
of the Attainment Date, and Reclassification of Several Areas
Classified as Moderate for the 2008 Ozone National Ambient Air Quality
Standards

AGENCY: Environmental Protection Agency (EPA).

ACTION: Final rule.

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

SUMMARY: The Environmental Protection Agency (EPA) is taking final
action for 11 ozone nonattainment areas that are classified as
``Moderate'' for the 2008 ozone national ambient air quality standards
(NAAQS). First, the agency is determining that two Moderate areas--
Baltimore, Maryland, and Mariposa County, California--attained the
standards by the July 20, 2018, applicable attainment date. Second, the
agency is granting a 1-year attainment date extension for the two
Moderate areas in Sheboygan County, Wisconsin--Inland Sheboygan County,
Wisconsin, and Shoreline Sheboygan County, Wisconsin. Third, the agency
is determining that seven Moderate areas failed to attain the standards
by the applicable attainment date--Chicago-Naperville, Illinois-
Indiana-Wisconsin; Dallas-Fort Worth, Texas; Greater Connecticut,
Connecticut; Houston-Galveston-Brazoria, Texas; Nevada County (Western
part), California; New York-North New Jersey-Long Island, New York-New
Jersey-Connecticut; and San Diego County, California. The effect of
failing to attain by the applicable attainment date is that these areas
will be reclassified by operation of law to ``Serious'' nonattainment
for the 2008 ozone NAAQS on September 23, 2019, the effective date of
this final rule. Accordingly, the responsible state air agencies must
submit State Implementation Plan (SIP) revisions and implement controls
to satisfy the statutory and regulatory requirements for Serious areas
for the 2008 ozone

NAAQS according to the deadlines established in this final rule.

DATES: This rule is effective on September 23, 2019.

I. Proposed Actions

A. Proposed Determinations of Attainment by the Attainment Date,
Determinations of Failure To Attain by the Attainment Date and
Extensions of the Attainment Date

    On November 14, 2018, the EPA proposed actions to fulfill its
statutory obligation under Clean Air Act (CAA or the Act) section 181
to determine whether 11 Moderate ozone nonattainment areas attained the
2008 ozone NAAQS by July 20, 2018, the applicable attainment date for
such areas.\1\
---------------------------------------------------------------------------

    \1\ 83 FR 56781, November 14, 2018 (FR is the Federal Register).
---------------------------------------------------------------------------

    First, the EPA proposed to find that two areas--Baltimore,
Maryland, and Mariposa County, California--attained the 2008 ozone
NAAQS by the applicable attainment date based on complete, quality-
assured and certified ozone air quality monitoring data for the 2015-
2017 calendar years.
    Second, the EPA proposed to grant state requests for a 1-year
extension of the attainment date from July 20, 2018, to July 20, 2019,
for two areas--Denver-Boulder-Greeley-Ft. Collins-Loveland, Colorado,
and Sheboygan County, Wisconsin. The proposed extensions were based on
the states' specific requests for such extensions and compliance with
the criteria under CAA section 181(a)(5)(B) and 40 CFR 51.1107,\2\
i.e., the fourth highest daily maximum 8-hour average ozone
concentration recorded in each area during the attainment year (2017
calendar year) did not exceed the 2008 ozone NAAQS level of 0.075 parts
per million (ppm), and the states certified that they were in
compliance with all requirements and commitments pertaining to the
areas in their respective applicable implementation plans. The EPA
proposed that upon the effective date of a final reclassification
action, the attainment date for these areas would be extended to July
20, 2019.
---------------------------------------------------------------------------

    \2\ CFR is Code of Federal Regulations.
---------------------------------------------------------------------------

    Third, the EPA proposed to find that seven areas failed to attain
the 2008 ozone NAAQS by the applicable attainment date and did not
qualify for a 1-year attainment date extension: Chicago-Naperville,
Illinois-Indiana-Wisconsin; Dallas-Fort Worth, Texas; Greater
Connecticut, Connecticut; Houston-Galveston-Brazoria, Texas; Nevada
County (Western part), California; New York-North New Jersey-Long
Island, New York-New Jersey-Connecticut; and San Diego County,
California. The proposed determination for each of these areas was
based upon complete, quality-assured and certified ozone air quality
monitoring data that showed that the 8-hour ozone design value for the
area exceeded 0.075 ppm for the period 2015-2017. The EPA proposed that
these seven areas would be reclassified as Serious nonattainment areas
by operation of law on the effective date of a final action finding
that these areas failed to attain the 2008 ozone NAAQS by the
applicable attainment date for Moderate areas.\3\ A summary of the
actions proposed for the 11 areas in the November 14, 2018, document is
provided in Table 1.
---------------------------------------------------------------------------

    \3\ See CAA section 181(b)(2)(A).

B. Proposed Serious Area SIP Submission Due Dates and RACT
Implementation Deadlines

    In the November 2018 proposal, the EPA also solicited comment on
adjusting the due dates, in accordance with CAA section 182(i), for SIP
submissions and setting deadlines for implementation of reasonably
available control technology (RACT) for ozone nonattainment areas that
would be reclassified to Serious. Under CAA section 181(b)(2), Moderate
nonattainment areas that fail to attain the 2008 ozone NAAQS by the
applicable attainment date for such areas will be reclassified as
Serious by operation of law upon the effective date of the final
reclassification action. Each responsible state air agency must
subsequently submit a SIP revision that satisfies the air quality
planning requirements for a Serious area under CAA section 182(c).
    On July 20, 2012, when final nonattainment designations became
effective for the 2008 ozone NAAQS, states responsible for areas
initially classified as Serious were required to submit SIP revisions
by due dates relative to that effective date. For those areas, the SIP
submission due dates ranged from 2 to 4 years after July 20, 2012,
depending on the required SIP ``element'' (e.g., 2 years, or July 20,
2014, for the RACT SIP, and 4 years, or July 20, 2016, for the
attainment demonstration). Since those dates have passed, the EPA
proposed in its November 2018 proposal to apply the Administrator's
discretion provided in CAA section 182(i) to adjust the Serious area
SIP due dates and certain implementation deadlines for newly
reclassified areas. CAA section 182(i) requires that reclassified areas
meet the applicable plan submission requirements ``according to the
schedules prescribed in connection with such requirements, except that
the Administrator may adjust any applicable deadlines (other than
attainment dates) to the extent such adjustment is necessary or
appropriate to assure consistency among the required submissions.''
With regard to RACT, the November 2018 proposal made a distinction
between RACT measures that would be needed for purposes of meeting
reasonable further progress (RFP) requirements or for attaining the
NAAQS expeditiously, and the possible set of RACT measures that
nevertheless are required to be adopted and implemented under the CAA
but would not necessarily be needed for a state to meet RFP or
demonstrate timely attainment in a particular nonattainment area.\4\ In
this final action, these two ``categories'' of RACT measures are
referred to as ``RACT measures tied to attainment'' and ``RACT measures
not tied to attainment,'' respectively.
---------------------------------------------------------------------------

    \4\ See 83 FR 62998, December 6, 2018; 40 CFR 51.1312(a)(2).
---------------------------------------------------------------------------

    First, the EPA proposed that states submit Serious area SIP
revisions (including RACT measures tied to attainment) and implement
those RACT measures no later than 12 months from the effective date of
the final reclassification action. Second, the EPA proposed the date
for submitting SIP revisions addressing RACT measures not tied to
attainment and implementing those measures as August 3, 2020, which is
the deadline for areas classified Moderate and higher for the 2015
ozone NAAQS to submit RACT SIP revisions.\5\ At the time of proposal,
the EPA estimated that August 3, 2020 would be approximately 18 months
after the effective date of its final reclassification action.\6\ In
the proposal, the EPA requested comment on an alternative that would
allow states to submit SIP revisions addressing RACT measures not tied
to attainment no later than 24 months from the effective date of the
final reclassification action. The EPA also requested comment on
whether a longer timeframe for implementing RACT measures not tied to
attainment (but no later than January 1, 2024, i.e., providing 5 years
from the anticipated date of reclassification,) would result in
significant emission reductions and improvement in air quality. The
EPA's rationale supporting its proposed due dates and deadlines is
summarized in the following sections.
---------------------------------------------------------------------------

    \5\ See 83 FR 62998, December 6, 2018; 40 CFR 51.1312(a)(2).
    \6\ See 83 FR 56781, November 14, 2018.
---------------------------------------------------------------------------

    1. Proposed due date for Serious-area SIP revisions (including RACT
measures tied to attainment), and Proposed implementation deadline for
RACT measures tied to attainment. The EPA proposed that states submit
all Serious-area SIP revisions--with the exception of any RACT measures
not tied to attainment--by no later than 12 months after the effective
date of the final reclassification action.\7\ The state

submittal requirements for nonattainment areas, in general, are
provided under CAA section 172(c); the SIP requirements that apply
specifically to Serious areas are listed under CAA section 182(c) and
include: (1) Enhanced monitoring; (2) an attainment demonstration and
RFP; (3) an enhanced vehicle inspection and maintenance program, if
applicable; (4) clean-fuel vehicle programs and transportation control
measures; (5) nonattainment New Source Review (NSR) program revisions;
and (6) contingency measures. States must also provide an analysis of--
and adopt all--reasonably available control measures (RACM), including
RACT needed for purposes of meeting RFP or timely attaining the NAAQS.
In the case of areas that are reclassified from Moderate to Serious for
the 2008 ozone NAAQS, such an analysis should include: (1) An
evaluation of controls for sources emitting 100 tons per year (tpy) or
more that may have become reasonably available since the January 1,
2017, Moderate area deadline for adopting and implementing RACT, and
(2) an evaluation of controls for sources emitting 50 tpy or more that
are currently reasonably available, consistent with the definition of
``major source'' or ``major stationary source'' for areas classified as
Serious.\8\
---------------------------------------------------------------------------

    \7\ The EPA has long taken the position that the statutory
requirement for states to assess and adopt RACT for sources in ozone
nonattainment areas classified Moderate and higher generally exists
independently from the attainment planning requirements for such
areas. See Memo from John Seitz, ``Reasonable Further Progress,
Attainment Demonstration, and Related Requirements for Ozone
Nonattainment Areas Meeting the Ozone National Ambient Air Quality
Standard'' (1995), at 5 (explaining that Subpart 2 requirements
linked to the attainment demonstration are suspended by a finding
that a nonattainment area is attaining but that requirements such as
RACT must be met whether or not an area has attained the standard);
see also 40 CFR 51.1118 (suspending attainment demonstrations, RACM,
RFP, contingency measures, and other attainment planning SIPs with a
finding of attainment). In addition to the independent RACT
requirement, states have a statutory obligation to apply RACM
(including such reductions in emissions from existing sources in the
area as may be obtained through implementation of RACT) to meet RFP
requirements and to demonstrate attainment as expeditiously as
practicable. Therefore, to the extent that a state adopts new or
additional RACT controls to meet RFP requirements or to demonstrate
attainment as expeditiously as practicable, those states must
include such RACT revisions with the other SIP elements due as part
of the attainment plan required under CAA sections 172(c) and 182(c)
and must implement them by the same date as explained further in
Section III.D.3 of this preamble.
    \8\ See CAA section 182(c).
---------------------------------------------------------------------------

    In CAA section 182(c), the schedule for submitting attainment
planning requirements for Serious areas is 4 years from the effective
date of nonattainment designation.\9\ As such, in accordance with CAA
section 182(i), EPA believed it was necessary to establish a shorter
deadline for all areas being reclassified to Serious, given that a due
date 4 years beyond reclassification would well surpass the Serious
area attainment date of July 20, 2021. EPA therefore proposed a 12-
month deadline for the Serious area attainment planning requirements
believing this timeframe to be appropriate for all the newly
reclassified areas, given that these areas are being reclassified
rather than newly designated, classified as Serious and have therefore
been adopting and implementing control measures to attain the 2008
ozone NAAQS for many years. The EPA considered the proposed timeframe
to be consistent with how the EPA handled setting SIP submission
deadlines for other nonattainment areas that were reclassified from
Moderate to Serious for past ozone NAAQS. Examples include Dallas-Ft.
Worth, Texas,\10\ an area reclassified in 2010 as Serious for the 1997
8-hour ozone NAAQS, and the Beaumont-Port Arthur, Texas,\11\ and St.
Louis, Missouri,\12\ nonattainment areas, reclassified in 2003 and
2004, respectively, from Moderate to Serious for the 1979 1-hour ozone
NAAQS. Based on these examples, the EPA considered that 12 months would
generally provide the time necessary for states and local air districts
to finish reviews of available control measures, adopt revisions to
necessary attainment strategies, address other SIP requirements and
complete the public notice process necessary to adopt and submit timely
SIP revisions.\13\
---------------------------------------------------------------------------

    \9\ See CAA section 182(c)(2) and (i) for SIP submissions and
requirements.
    \10\ See 75 FR 79302, December 20, 2010, Dallas-Ft. Worth,
Texas, reclassification to Serious for the 1997 8-hour ozone NAAQS.
    \11\ See 69 FR 16483, March 30, 2004, Beaumont-Port Arthur,
Texas, reclassification to Serious for the 1979 1-hour ozone NAAQS.
    \12\ See 68 FR 4836, January 30, 2003, St. Louis, Missouri,
reclassification to Serious for the 1979 1-hour ozone NAAQS.
    \13\ Cf. CAA section 179(d)(1).
---------------------------------------------------------------------------

    The EPA also proposed that any RACT that states determine is needed
for meeting RFP or timely attainment of the 2008 ozone NAAQS would need
to be implemented by the date that the attainment plan is due, i.e., no
later than 12 months after the effective date of the final
reclassification action. As a general matter, the Act requires
implementation of those requirements needed for timely attainment ``as
expeditiously as practicable.'' \14\ The EPA considered an
implementation deadline of 12 months from the anticipated effective
date of the final reclassification action to be consistent with the
requirement to act expeditiously. Moreover, at the time of the November
2018 proposal, EPA anticipated that a 12-month deadline would be
generally consistent with the start of the attainment year ozone season
for all 2008 ozone NAAQS Serious areas (early 2020). Ideally, all
emissions control strategies designed to help areas attain the 2008
ozone NAAQS by the applicable Serious area attainment date of July 20,
2021, or to qualify for a 1-year extension of that attainment date,
would be in place and in effect for the start of the final full ozone
season preceding the attainment date, as that is the last ozone season
of air quality monitoring data that could affect the area's design
value as of the attainment date or would decide whether the area met
the 1-year extension air quality eligibility criterion.\15\
---------------------------------------------------------------------------

    \14\ See CAA section 172(c)(1).
    \15\ See 40 CFR 51.1108(d).
---------------------------------------------------------------------------

    Due dates for SIP submission often precede the deadline for
implementation of control strategies contained in those SIP
submissions. However, given the compressed timeframe available for
states to meet the July 20, 2021, attainment date for Serious areas,
the EPA considered that, at the very least, it would be appropriate to
align the due date for RACT SIP submissions with the deadline for
implementation of any new control measures contained in that RACT SIP.
    2. Proposed due date for Serious-area SIP revisions for RACT
measures not tied to attainment. The EPA proposed that states submit
their SIP revisions by August 3, 2020, for any RACT not otherwise
needed for attainment purposes, which was based on our prediction that
such a due date would be approximately 18 months after the effective
date of the final reclassification action. The proposed August 3, 2020,
due date would have aligned the 2008 ozone Serious area SIP due date
for RACT measures not tied to attainment with the SIP revision due
dates for RACT (areas classified Moderate or higher) and certain other
implementation plan elements required for 2015 ozone NAAQS
nonattainment areas.\16\
---------------------------------------------------------------------------

    \16\ All the areas reclassified because of this final rule are
among those designated nonattainment for the 2015 ozone NAAQS,
effective August 3, 2018 (see 83 FR 25776, June 4, 2018).
---------------------------------------------------------------------------

    As provided for in CAA section 182(i), the Administrator may adjust
deadlines for reclassified areas ``to the extent such adjustment is
necessary or appropriate to assure consistency among the required
submissions.'' In the November 2018 proposal, the EPA interpreted
``consistency among the required submissions'' to allow for
consideration of ``required submissions'' for various ozone NAAQS that
are being implemented simultaneously. Since all the areas that are
subject to reclassification to Serious upon the effective date of this
final reclassification action are also designated nonattainment for the
2015 ozone NAAQS or are in the Ozone Transport Region (OTR), the same
state air agencies are required under CAA section 182 to submit SIP
revisions for certain SIP elements for the 2015 ozone

NAAQS within 2 years of the effective date of the nonattainment area
designations. The effective date of nonattainment area designations for
the 2015 ozone NAAQS was August 3, 2018, and therefore the due date for
submitting nonattainment SIP revisions associated with that standard is
August 3, 2020. Consistent with CAA section 182(i), the EPA considered
coordinating the SIP due dates related to the 2008 and 2015 ozone NAAQS
for these nonattainment areas to be ``appropriate'' and could result in
more effective implementation of the NAAQS.
    Under CAA section 182(i), reclassified areas generally are required
to submit SIP revisions associated with their new classification
``according to the schedules prescribed in connection with such
requirements.'' CAA section 182(b)(2), which establishes the RACT
requirement for ozone nonattainment areas classified as Moderate or
above, and CAA section 184(b), which establishes RACT requirements for
states in the ozone transport region, provide a 24-month schedule for
compliance with those requirements.\17\ Although the proposed due date
of August 3, 2020, would have provided states with less than 24 months
to submit their SIP revisions for RACT measures not tied to attainment,
the EPA considered the anticipated timeframe to be ``appropriate''
given coordination with the 2015 ozone NAAQS SIP due dates and the
nature of the submission, i.e., because states with newly reclassified
Serious areas should recently have addressed RACT requirements
commensurate with the Moderate area classification, such that their
Serious area RACT SIP submittal should primarily only have to address
sources emitting between 50-100 tpy. The EPA also requested comment on
an alternative approach that would have allowed states a full 24 months
from the effective date of the final reclassification action to submit
SIP revisions for RACT not otherwise needed for attainment, if such
additional time would yield significant emission reductions and
improvement in air quality.
---------------------------------------------------------------------------

    \17\ See 40 CFR 51.1112(a)(2).
---------------------------------------------------------------------------

    3. Implementation deadline for Serious-area RACT measures not tied
to attainment. CAA section 182(b)(2) establishes the RACT area
requirements for ozone areas designated and classified Moderate and
higher.\18\ That provision, which was written for the 1-hour ozone
NAAQS, established a RACT implementation deadline of approximately 5
years from November 15, 1990. In the 2008 ozone NAAQS SIP Requirements
Rule, the EPA interpreted this statutory deadline for the 2008 ozone
standard by establishing a RACT implementation deadline of January 1 of
the fifth year after the effective date of nonattainment designation,
and explained that this was consistent with the maximum timeframe
provided under the CAA for implementing RACT in nonattainment areas
classified Moderate or higher.\19\ For nonattainment areas initially
classified as Moderate or higher for the 2008 ozone NAAQS and for OTR
states, RACT measures were required to be implemented by January 1,
2017. Because that date has now passed and cannot be applied to the
areas that are subject to reclassification to Serious, the EPA proposed
to set a new deadline of August 3, 2020, for implementation of any new
RACT requirements not otherwise needed for RFP or timely attainment
purposes.
---------------------------------------------------------------------------

    \18\ CAA Section 182(b)(2) sets the RACT requirement for
Moderate areas, and the Act requires other higher-classified areas
to fulfill the CAA section 182(b) requirements. See CAA sections
182(c), (d), and (e) (requiring states with Serious, Severe, and
Extreme nonattainment areas, respectively, to also fulfill the
obligations required of lower-classified areas).
    \19\ See 40 CFR 51.1112(a)(3); 80 FR 12264, 12280, March 6,
2015.
---------------------------------------------------------------------------

    This proposed deadline of August 3, 2020, was based on EPA's
estimation at proposal that the date would be approximately 18 months
after the anticipated effective date of the final reclassification
action. EPA also proposed the same date for the submission due date for
related SIP revisions for RACT measures not tied to attainment
discussed in Section I.B.2 of this final reclassification action.
    Areas originally classified as Moderate and higher for the 2008
ozone NAAQS had just under 5 years to implement ozone RACT requirements
(by January 1 of the fifth year after the effective date of
designation, i.e., January 1, 2017). By contrast, areas reclassified in
2016 from Marginal to Moderate for the 2008 ozone NAAQS became subject
to the RACT requirement less than seven months (and in two cases
significantly less than seven months) before the RACT implementation
deadline.20 21 22 In some reclassified Moderate areas,
states may have been able to adopt additional controls as RACT had
there been additional time to implement them. In their proposal the
EPA, therefore, also solicited comment on whether an extended RACT
implementation deadline--beyond August 3, 2020, but no later than
January 1 of the fifth year after the effective date of
reclassification to Serious (i.e., January 1, 2024)--would yield
additional and substantial emission reductions in newly-reclassified
Serious areas beyond what could be achieved by the due date of August
3, 2020.

II. Significant Events Following EPA's November 2018 Proposal

    Following EPA's issuance of the November 2018 proposal, two
significant events occurred which have bearing on this final rule.
First, on March 26, 2019, the State of Colorado's Governor Jared Polis
sent a letter to EPA to withdraw the state's request for a 1-year
attainment date extension.\23\ As stated in the Act's attainment date
extension provision for ozone nonattainment areas, section 181(a)(5),
``[u]pon application by any State,'' the EPA may extend an area's
attainment date by 1 year provided certain criteria are met. The EPA
interprets a state's application to be a necessary prerequisite to
granting the 1-year extension.\24\ Because the Governor has withdrawn
the request, this rulemaking does not finalize the 1-year extension for
the Denver-Greeley-Ft. Collins-Loveland, CO, nonattainment area for the
2008 ozone NAAQS.
---------------------------------------------------------------------------

    \23\ See docket item EPA-HQ-OAR-2018-0226-0059, ``GOV Letter
Attainment Extension withdrawal 3.26.2019.''
    \24\ Cf. Del. Dep't of Natural Res. and Envtl. Control v. EPA,
895 F.3d 90 (D.C. Cir. 2018) (interpreting section 181(a)(5)'s
reference to ``any'' state literally to provide EPA with authority
to grant an extension to a multi-state nonattainment area based on
the extension request of only one state in that area).
---------------------------------------------------------------------------

    Second, since the EPA issued its November 2018 proposal, the agency
has taken final action to approve a request from the State of Wisconsin
to revise the designation for the Sheboygan County nonattainment area
for the 1997 and 2008 primary and secondary ozone NAAQS, by splitting
the historic nonattainment area into two distinct nonattainment areas
that together cover the identical geographic area of Sheboygan County,
Wisconsin.\25\ For purposes of this action, the former Sheboygan County
2008 ozone moderate nonattainment area is now the ``Inland Sheboygan
County, WI,'' nonattainment area and the ``Shoreline Sheboygan County,
WI,'' area. Because the boundary of the two nonattainment areas
together covers the entire historic nonattainment area, for which EPA

proposed a 1-year extension of the attainment date for the 2008 ozone
NAAQS in November 2018, the EPA is taking final action to grant a 1-
year extension of the Moderate area attainment date to July 20, 2019
for both areas.\26\ The EPA may grant a 1-year attainment date
extension for the two areas because air quality data for each area,
evaluated independently, shows the 2017 fourth-highest 8-hour ozone
value for the Inland Sheboygan County, WI, nonattainment area was 0.070
ppm, and the corresponding value for the Shoreline Sheboygan County,
WI, nonattainment area was 0.075 ppm. Furthermore, the other statutory
criteria for qualifying for a 1-year attainment date extension for an
ozone nonattainment area are met.\27\
---------------------------------------------------------------------------

    \25\ See 84 FR 33699, July 15, 2019; effective July 15, 2019.
    \26\ See Section III.B of this preamble.
    \27\ The Wisconsin Department of Natural Resources requested an
extension for the Sheboygan County, WI, nonattainment area and
certified its implementation plan applicable for the entire historic
geographic area.
---------------------------------------------------------------------------

III. Final Actions

    The public comment period for EPA's November 2018 proposal closed
on December 14, 2018. To accommodate a request for a public hearing,
the comment period was subsequently reopened on February 8, 2019, a
public hearing was held on February 15, 2019, and the comment period
closed on February 22, 2019.
    All comments received during these two public comment periods may
be found in the electronic docket for this final action. In this
section describing EPA's final actions, certain key comments and the
agency's responses are included. A Response to Comments document
including all significant comments received on the EPA's proposal and
the agency's responses to those comments is also included in the docket
for this rulemaking. To access the full set of comments received and
the Response to Comments document, please go to http://www.regulations.gov and search for Docket No. EPA-HQ-OAR-2018-0226, or
contact the person listed in the FOR FURTHER INFORMATION CONTACT
section.
    Due to the withdrawal of Colorado's request for a 1-year attainment
date extension, EPA is not taking final action for the Denver-Boulder-
Greeley-Ft. Collins-Loveland, CO, nonattainment area in this final
rule. However, EPA is finalizing the attainment date extension for both
portions of the historic Sheboygan, Wisconsin, nonattainment area
(i.e., Inland Sheboygan County, WI, and Shoreline Sheboygan County,
WI), which now counts as two nonattainment areas. A summary of EPA's
final actions for the 11 Moderate nonattainment areas in provided in

A. Determinations of Attainment by the Attainment Date

    Pursuant to section 181(b)(2)(A) of the CAA and 40 CFR 51.1103, the
EPA is making final determinations that the Baltimore, MD, and Mariposa
County, CA, Moderate nonattainment areas listed in Table 2 attained the
2008 ozone NAAQS by the applicable attainment date of July 20, 2018.
Once effective, this final action satisfies the EPA's obligation
pursuant to CAA section 181(b)(2)(A) to determine, based on an area's
air quality as of the attainment date, whether the area attained the
standard by the applicable attainment date. The effect of a final
determination of attainment by an area's attainment date is to
discharge the EPA's obligation under CAA section 181(b)(2)(A), and to
establish that, in accordance with CAA section 181(b)(2)(A), the area
will not be reclassified for failure to attain by the applicable
attainment date.
    These determinations of attainment do not constitute a
redesignation to attainment as provided for under CAA section
107(d)(3). Redesignations require states to meet additional statutory
criteria, including the EPA approval of a state plan demonstrating
maintenance of the air quality standard for 10 years after
redesignation, as required under CAA section 175A. As for all NAAQS,
the EPA is committed to working with states that choose to submit
redesignation requests for the 2008 ozone NAAQS.\28\
---------------------------------------------------------------------------

    \28\ It is worth noting that EPA issued Clean Data
Determinations, which suspend certain attainment planning
requirements, for both the Baltimore, Maryland, and Mariposa,
California, 2008 ozone NAAQS nonattainment areas. For Baltimore,
Maryland, the final 2008 ozone NAAQS Clean Data Determination was
effective on July 1, 2015 (80 FR 30941, June 1, 2015). For Mariposa,
California, EPA issued a final 2008 ozone NAAQS Clean Data
Determination that was initially effective on February 21, 2017 (81
FR 93624, December 21, 2016) and was delayed until March 21, 2017,
due to a Presidential Directive (82 FR 8499, January 26, 2017). More
information about the Clean Data Policy and redesignation guidance
is available at https://www.epa.gov/ozone-pollution/redesignation-and-clean-data-policy-cdp.
---------------------------------------------------------------------------

    Comment: One commenter suggested that the record supporting the
Baltimore, Maryland, reclassification action was incomplete because it
appeared that the state relied on two exceptional events claims for
Canadian wildfires impacting air quality in Baltimore in May and July
2016.\29\ The commenter claimed that the EPA failed to clearly identify
the basis for its action in the docket. The commenter also suggested
that Maryland appears to be the only state to claim that the July 2016
wildfires justified exclusion of any air quality data, indicating that
Maryland's

demonstration and the EPA's acceptance of the data exclusion were
arbitrary and not valid.
---------------------------------------------------------------------------

    \29\ See comments from Earthjustice, docket item EPA-HQ-OAR-
2018-0226-0050.
---------------------------------------------------------------------------

    Response: The EPA acknowledges that it inadvertently omitted from
the record for this proposed action the supporting information received
from Maryland regarding these exceptional events claims. The EPA
therefore issued a supplemental proposal in the Federal Register on May
7, 2019.\30\ This supplemental proposal made available the exceptional
events demonstration relied upon by Maryland to support the exclusion
of air quality data for the Baltimore area due to Canadian wildfire
impacts in May and July 2016. Comments were solicited for a 15-day
period through May 22, 2019. No substantive comments requiring a
response were received.
---------------------------------------------------------------------------

    \30\ See 84 FR 19893, May 7, 2019; and docket item EPA-HQ-OAR-
2018-0226-0061.
---------------------------------------------------------------------------

B. Extension of the Moderate Area Attainment Date

    Pursuant to CAA section 181(a)(5), the EPA is taking final action
to grant a 1-year extension of the applicable attainment date from July
20, 2018, to July 20, 2019, for the two nonattainment areas in
Sheboygan County, Wisconsin--Inland Sheboygan County, WI, and Shoreline
Sheboygan County, WI.\31\
---------------------------------------------------------------------------

    \31\ Subsequent to EPA's proposal to extend the 2008 ozone
Moderate area attainment deadline for the Sheboygan County
nonattainment area, the EPA approved Wisconsin's request to split
the area into two distinct nonattainment areas. See 84 FR 33699,
July 15, 2019; effective July 15, 2019. See also Section II of this
preamble.
---------------------------------------------------------------------------

    The EPA is not taking final action to grant a 1-year extension for
the Denver area because the State withdrew its request for an
extension, and the EPA interprets that request to be a necessary
prerequisite to an extension of the attainment date under CAA section
181(a)(5). The EPA is therefore addressing whether the Denver area
attained the 2008 ozone NAAQS by the July 20, 2018 attainment date and
any associated reclassification in a separate action.
    Comment: One commenter opposed an attainment date extension for the
Sheboygan area. The commenter claimed that because the ``extension
year'' runs from July 2018 to July 2019, and the year preceding the
Extension Year runs from July 2017 to July 2018, then the relevant
monitoring data for making the CAA section 181(a)(5)(B) extension
determination should be from the July 2017 to July 2018 period. The
commenter noted that during this period, one of the Sheboygan County
monitors recorded a fourth-highest daily maximum 8-hour average of
0.081 ppm, and they claimed that for this reason the area does not
qualify for a 1-year attainment date extension.
    Response: The EPA does not agree with the commenter because a 1-
year attainment date extension for an ozone nonattainment area is based
on air quality data for the most recent calendar year prior to the
attainment date. This interpretation of CAA section 181(a)(5)(B) is
explained in the SIP requirements rule for the 2008 ozone NAAQS.\32\ As
noted in Table 1, the fourth-highest 8-hour ozone value during 2017 for
the historic Sheboygan County nonattainment area was below the level of
the standard. Furthermore, as noted in Section II of this preamble,
when analyzed separately, the fourth-highest 8-hour ozone value during
2017 for each of the ``new'' attainment areas in Sheboygan County
(i.e., Inland Sheboygan County,WI, and Shoreline Sheboygan County, WI),
was below the level of the standard, and thus Sheboygan County, now
separated into two nonattainment areas, qualifies for a 1-year
attainment date extension.
---------------------------------------------------------------------------

    \32\ See 80 FR 12292 (March 6, 2015) and 40 CFR 51.1107.
---------------------------------------------------------------------------

C. Determinations of Failure To Attain and Reclassification

    Pursuant to CAA section 181(b)(2), the EPA is finalizing its
proposed determinations that the seven Moderate nonattainment areas
listed in Table 2 have failed to attain the 2008 ozone NAAQS by the
applicable attainment date of July 20, 2018. Therefore, upon the
effective date of this final action, these seven areas will be
reclassified, by operation of law, to Serious for the 2008 ozone NAAQS.
Once reclassified to Serious, these areas will be required to attain
the standard ``as expeditiously as practicable'' but no later than 9
years after the initial designation as nonattainment, which in this
case would be no later than July 20, 2021. If any of these areas
attains the 2008 ozone NAAQS prior to the Serious area attainment date,
the relevant state may request redesignation to attainment, provided
the state can demonstrate that the criteria under CAA section
107(d)(3)(E) are met.\33\
---------------------------------------------------------------------------

    \33\ See more information about the Clean Data Policy and
redesignation guidance is available at https://www.epa.gov/ozone-pollution/redesignation-and-clean-data-policy-cdp.
---------------------------------------------------------------------------

    Following the November 2018 proposal, the California Air Resources
Board submitted a request under CAA section 181(b)(3) to voluntarily
reclassify the Nevada County (Western part) nonattainment area from
Moderate to Serious nonattainment for the 2008 ozone standards.\34\ The
State's request for voluntary reclassification was accompanied by a SIP
revision that addresses Serious area attainment, RFP, RACM and other
planning requirements.\35\ The State previously submitted a SIP
revision to address the Serious-area RACT requirements on June 7,
2018,\36\ and a SIP revision to address NSR requirements for the 2008
ozone standard on September 6, 2016.\37\ In this final action, the EPA
is finding that the Nevada County (western part), California area
failed to attain the 2008 ozone standard by the applicable attainment
date, which means the area will be reclassified to Serious by operation
of law. The EPA notes that there is no need for the EPA to act on the
request for voluntary reclassification because the EPA's final
determination here results in the same outcome as would occur with an
approval of that request--in either scenario, the area would be
reclassified to Serious, and subject to the Serious area requirements
described in CAA section 182(c).
---------------------------------------------------------------------------

    \34\ See the December 2, 2018, letter from California Air
Resources Board (CARB) Executive Officer Richard W. Corey to EPA
Region 9 Regional Administrator Michael Stoker, transmitting CARB
Resolution 18-36, and November 14, 2018 letter from Northern Sierra
Air Quality Management District (NSAQMD) Executive Director Gretchen
Bennitt to CARB Executive Officer Richard W. Corey, transmitting
NSAQMD Resolution 2018-07.
    \35\ The Northern Sierra Air Quality Management District, which
has local jurisdiction over the area, adopted the Ozone Attainment
Plan for Western Nevada County on October 22, 2018. The California
Air Resources Board adopted the plan as a revision to the California
SIP on November 15, 2018.
    \36\ The Northern Sierra Air Quality Management District adopted
the Reasonably Available Control Technology (RACT) State
Implementation Plan (SIP) Revision for Western Nevada County 8-hour
Ozone Nonattainment Area on March 26, 2018. The California Air
Resources Board Executive Officer adopted the Plan as a revision to
the California SIP on June 7, 2018.
    \37\ The Northern Sierra Air Quality Management District adopted
District Rule 428: New Source Review Requirements for New and
Modified Major Sources in Federally Designated Nonattainment Areas
on June 27, 2016. The California Air Resources Board Executive
Officer adopted the rule as a revision to the California SIP on
September 6, 2016.
---------------------------------------------------------------------------

    The EPA received some adverse comments on its proposal to determine
that certain areas failed to attain by the applicable attainment date
and to reclassify those areas to Serious nonattainment. For a
discussion of additional comments received on the proposal and
responses to those comments, please see the Response to Comments
document in the docket for this action.
    Comment: Several commenters noted that when the Chicago area was
designated as nonattainment for the

more stringent 2015 ozone NAAQS,\38\ a portion of Lake County, Indiana,
and all of Porter County, Indiana, were designated as attainment rather
than being included as part of the Chicago, IL-IL-WI, nonattainment
area for the more stringent 2015 ozone NAAQS. For this reason, the
commenters oppose the inclusion of these Indiana counties in the
reclassification of the Chicago nonattainment area to Serious for the
2008 ozone NAAQS.
---------------------------------------------------------------------------

    \38\ See 83 FR 25776, June 4, 2018; final rule effective August
3, 2018.
---------------------------------------------------------------------------

    Response: Although the Chicago, IL-IN-WI, nonattainment area for
the 2015 ozone NAAQS consists of a smaller geographic area than the
Chicago-Naperville, IL-IN-WI, nonattainment area for the 2008 ozone
NAAQS, the differences in the geographic extent of the nonattainment
areas does not constitute a revision to the nonattainment area boundary
for the 2008 ozone NAAQS. Under CAA section 181(b)(2), when the EPA
determines that an area has failed to attain a standard by the
applicable attainment date, that area is reclassified by operation of
law to the next higher classification for the area or the
classification applicable to the area's design value as of the date EPA
determines the area failed to attain. Because the Chicago-Naperville,
IL-IN-WI, nonattainment area for the 2008 ozone NAAQS failed to attain
the standard by its Moderate attainment date, the EPA is required by
the CAA to reclassify the area, not a portion of the area, to Serious.
The boundary of the nonattainment area for a different NAAQS, in this
case the 2015 ozone NAAQS, has no relevance on the EPA's duties with
respect to the 2008 ozone NAAQS.
    Comment: One commenter suggested that the Houston, Texas, area
should not be reclassified to Serious for the 2008 ozone NAAQS because
certain days in 2018 were impacted by exceptional events, and if such
events were taken into account, the area would attain the standard
based on 2016-2018 data.
    Response: The CAA section 181(b)(2)(A) requires the EPA
Administrator to determine whether an area attained the 2008 ozone 8-
hour NAAQS based on the area's 2015-2017 design value as of the
attainment date, July 20, 2018. Based on these data, the Houston area
is being reclassified to Serious as of the effective date of this final
action. The EPA will review any exceptional events demonstrations that
may be provided by Texas in the future, and the EPA will determine if
it concurs with such demonstrations. If Houston or any other area that
has been reclassified to Serious provides the EPA with quality-assured,
certified air quality data for 2016-2018 that demonstrates attainment
of the 2008 ozone NAAQS, the area could be eligible for a clean data
determination,\39\ which would suspend the obligation to submit the
attainment planning elements so long as the area continues to attain
the standard. Such areas would also be able to submit a request for
redesignation provided they meet the statutory criteria for
redesignation, including an approved maintenance plan.

redesignation guidance is available at https://www.epa.gov/ozone-pollution/redesignation-and-clean-data-policy-cdp.
---------------------------------------------------------------------------

    Comment: One commenter claimed that Connecticut has failed to
attain the 2008 ozone NAAQS by the applicable attainment date due to
emissions it does not have authority to control, either because such
emissions originate out of state or are from mobile sources regulated
by EPA. The commenter believes that EPA failed to adequately address
interstate transport of air pollution under CAA section 110(a)(2)(D)
for the 2008 ozone NAAQS when it finalized the 2016 Cross-State Air
Pollution Rule (CSAPR) Update. They claimed that the underlying logic
of this rule was flawed because the EPA limited its assessment of
control strategies to those that were feasible to implement only as
late as the 2017 ozone season. The commenter recommends that the EPA
revisit this transport rule to address longer term control strategies
that could be feasible to implement beyond 2017 to benefit air quality
in areas reclassified to Serious and beyond.
    Response: The agency's mandatory duty to make determinations of
attainment or failure to attain the NAAQS is contained in CAA section
182(b)(2), which does not reference or make any exclusions based on the
nature or effect of transported emissions on monitored air quality data
in a given nonattainment area.\40\ Moreover, to the extent the comment
is raising issues related to the EPA's separate action, the CSAPR
Update, to address the requirements of CAA section 110(a)(2)(D), or the
``good neighbor'' provision, with respect to the 2008 ozone NAAQS, they
are outside the scope of this final determination and should be
addressed in the context of those EPA actions.\41\ Nevertheless, the
EPA acknowledges the role interstate transport of precursors to ozone
pollution plays in the efforts of downwind areas to attain and maintain
the NAAQS. The EPA finalized a determination in December 2018, the
``CSAPR Close Out,'' that fulfilled its statutory obligations under CAA
section 110(a)(2)(D), or the ``good neighbor'' provision, with respect
to the 2008 ozone NAAQS.\42\ In that determination, the EPA's air
quality modeling projected that all monitors in the Eastern United
States, including those air quality monitors in Connecticut, would be
attaining and maintaining the NAAQS by 2023, the analytic year used by
the agency.\43\ Id.

D. Serious Area SIP Submission Deadlines and RACT Implementation
Deadlines

    The EPA received comments on the proposed alternatives for the
Serious area deadlines for submitting SIP and RACT revisions, and on
the deadlines for implementation of RACT. After full consideration of
those comments, and pursuant to CAA section 182(i), the EPA is
finalizing the SIP submission due dates and RACT implementation
deadlines.
    1. Due date for Serious area SIP revisions (including RACT measures
tied to attainment), and implementation deadline for RACT measures tied
to attainment. The EPA is finalizing August 3, 2020, as the due date
for Serious area SIP revisions, including RACT measures tied to
attainment. The EPA is also finalizing August 3, 2020, as the
implementation deadline for RACT measures tied to attainment.
    The EPA's decision to finalize the date of August 3, 2020, for
these deadlines was informed by several factors. The EPA proposed a due
date of 12 months from the effective date of a final action for these
SIP elements and the implementation deadline for RACT measures tied to
attainment in its November 2018 proposal. At the time of proposal, the
agency had hoped to issue a timely final action--by January 2019. Under
such a scenario, the actual due dates for Serious area SIP submissions
and deadlines for implementation of RACT measures tied to attainment

would have been January 2020, the beginning of the final year of the 3-
year period (2018-2020) that would be evaluated to determine whether an
area attains the 2008 ozone NAAQS by the July 20, 2021, Serious-area
attainment date. This intended schedule would have enabled the state to
implement controls by the beginning of 2020, the last year for which
air quality data could impact an area's ability to timely attain the
NAAQS or to achieve qualifying air quality for a 1-year extension of
the attainment deadline from July 20, 2021, to July 20, 2022.
    The timeliness of the final action was delayed when the EPA
received a request to schedule a public hearing on the proposal around
the time of the lapse in government appropriations, otherwise referred
to as the Federal Government shutdown, occurred beginning on December
22, 2018, and ended January 25, 2019. Consequently, while the original
public comment period for the November 2018 proposal closed on December
14, 2018, the EPA was unable to hold a public hearing in December. As
quickly as possible after the shutdown ended, and the Government
resumed normal operations, the EPA reopened the public comment period
on February 8, 2019, held the public hearing on February 15, 2019,\44\
and closed the public comment period on February 22, 2019. After
considering the time that it would take to finalize the rule after the
lapse in federal government appropriations, the EPA determined that
finalizing the Serious area SIP due date and implementation deadline
for RACT measures tied to attainment at 12 months from the effective
date of a final rule would result in deadlines falling on a date close
to August 3, 2020. Based on this revised timing scenario, and
considering comments supporting the alignment of SIP due dates and
deadlines for the 2008 and 2015 ozone NAAQS, the EPA determined that it
would be appropriate in this case to finalize a due date for Serious
Area SIP revisions, including RACT measures tied to attainment, and
deadline for implementation of those RACT measures of August 3, 2020,
in order to ensure greater consistency among the submissions and
implementation for both NAAQS.
---------------------------------------------------------------------------

    \44\ EPA is required under the Administrative Procedure Act
(APA) to provide adequate notice of a public hearing (see 5 U.S.C.
553).
---------------------------------------------------------------------------

    More specifically, although the EPA did not propose August 3, 2020,
as a due date for these particular SIP submissions, the date was
proposed as the due date for SIP revisions addressing RACT measures not
tied to attainment and proposed for the deadline for implementation of
those RACT measures. In the November 2018 proposal, the EPA provided
its rationale for proposing August 3, 2020, to provide for
``consistency among submissions'' that may be due from a nonattainment
area for more than one NAAQS. For the reasons provided to proposing the
August 3, 2020, due date for SIP submissions and the deadline for
implementation of RACT measures not tied to attainment, the EPA
believes that establishing August 3, 2020, as the due date for Serious-
area SIP submissions (including RACT measures tied to attainment) and
the implementation deadline of those RACT measures, would more
effectively meet the objective of having consistency among submissions
pursuant to CAA section 182(i), rather than a deadline that is 12
months from the effective date of this final rule.
    Comment: Some commenters opposed the proposed deadline of 12 months
from the effective date of the final action for SIP submissions and
implementation of RACT measures tied to attainment because it would not
provide a reasonable amount of time to evaluate control options,
conduct rulemaking, and give affected sources sufficient time to
implement control requirements. These commenters preferred a period of
18 months or more for Serious Area SIP submission due dates and
implementation deadlines for RACT measures tied to attainment. Other
commenters supported the proposed 12-month due date for SIP submissions
and implementation deadline for RACT measures tied to attainment
because they claimed that any additional delay would only extend the
duration of unnecessary adverse health impacts on nonattainment area
residents. One commenter stated that, because the EPA is directed to
streamline SIP submittals when it considers appropriate due dates after
reclassification, the EPA should set a due date for Serious area SIP
submittals under the 2008 ozone NAAQS that is consistent with the
August 3, 2020, deadline for the Moderate area SIP submittals that will
be due under the 2015 ozone NAAQS. The commenter indicated that states
could realize significant savings of limited state resources if these
2015 ozone Moderate area and 2008 ozone Serious area SIP due dates were
coordinated.
    Response: As discussed earlier, CAA section 182(i) provides
authority to the Administrator to adjust SIP submission due dates as
necessary or appropriate to assure consistency among SIP submissions.
Although the specific date of August 3, 2020 was not included as an
option in the November 2018 proposal, the EPA is persuaded by comments
received supporting this date because setting such a due date pursuant
to the authority of CAA section 182(i) could allow states to save
limited resources by consolidating two SIPs into a single submission.
In addition, given the timing of this final action, the August 3, 2020
SIP submission due date will be relatively close in time to 12 months
after this final action becomes effective, consistent with due dates
established by EPA in past ozone reclassification actions from Moderate
to Serious, which was discussed in the proposal. With regard to
commenters seeking an 18-month period or longer for developing SIP
revisions, the EPA notes that states with areas that were proposed for
reclassification in November 2018 have known with a reasonable amount
of certainty that revised implementation plans would be due in the near
future to provide for expeditious attainment of the 2008 ozone NAAQS,
and have had the opportunity to make progress on plan development
activities before issuance of this final action. Nonetheless, the EPA
recognizes the challenges posed by these due dates and deadlines and is
committed to working closely with states to help them as they prepare
SIP revisions in a timely manner.
    2. Due date for submitting SIP revisions for RACT measures not tied
to attainment. For SIP revisions for RACT measures not tied to
attainment, the EPA proposed a due date of August 3, 2020, which would
have been about 18 months from the anticipated effective date of the
final action (anticipated in early 2019). The EPA also requested
comment on an alternative due date for submitting SIP revisions for
RACT measures not tied to attainment that would have been 24 months
from the effective date of the final action, i.e., ``according to the
schedule[ ] prescribed in connection with such requirement[ ].'' \45\
Taking in to account several comments on these proposed dates and the
circumstances surrounding the timing of this final action, the EPA is
finalizing a due date for SIP revisions for RACT measures not tied to
attainment of 18 months from the effective date of this final action,
as explained further below.
---------------------------------------------------------------------------

    \45\ See CAA section 182(i).
---------------------------------------------------------------------------

    The proposal's due date of August 3, 2020, for RACT submissions not
tied to attainment was expected to be roughly 18 months from the
effective date of the

anticipated final action. By proposing such a date, the EPA recognized
that these measures could reasonably be submitted after the attainment
year ozone season (2020) relevant to the Serious area attainment date,
because these measures were explicitly not tied to the area's ability
to achieve timely attainment. In taking comment on providing a due date
that accounted for a full 24 months to prepare a RACT submission, the
EPA suggested that such additional time could yield a more desirable
end result in terms of emissions reductions and air quality benefits,
reducing state processing and resource burdens, and/or burden on
emissions sources.
    While EPA is not electing to finalize a due date of 24 months from
the effective date of this action (approximately August 2021), we are
also electing not to finalize a due date of August 3, 2020, given that
such a date would provide just under 12 months from the effective date.
Because the measures that states identify as ``reasonably available''
are directly tied to the time provided by the EPA in establishing such
a due date, providing a slightly longer timeframe (i.e., 18 months
rather than 12 months) to identify and submit RACT measures not tied to
attainment for newly reclassified Serious areas for the 2008 standards
could lead states to determine that additional controls are reasonable,
thus helping areas attain both the 2008 and 2015 standards more
expeditiously. Areas subject to this newer due date should have already
implemented RACT for sources emitting 100 tpy or more of volatile
organic compounds (VOC) or nitrogen oxides (NOX) under their
Moderate area requirements. Therefore, at this stage, states should be
primarily focused on identifying and adopting new RACT measures
required to control sources emitting between 50 to 100 tpy of VOC or
NOX. The EPA believes that 18 months would provide adequate
time to adopt any new controls determined to be RACT for this group of
sources and submit a SIP to the EPA accordingly.
    Comment: Several commenters supported either the proposed August
2020 due date or a due date of 18 months from the effective date of
this final action. One commenter stated that a period of at least 18
months is needed to properly identify and evaluate potential controls
and conduct necessary rulemaking at the state level. Another commenter
believed that there was no justification for a due date any earlier
than the July 2021 Serious-area attainment date because this SIP
submission would be for RACT not needed for the area to attain. A third
commenter supported the August 2020 due date because it would provide
for aligned SIP submittal due dates for 2008 ozone Serious areas and
for 2015 ozone Moderate areas.
    Response: Section 182(i) of the CAA provides that states shall meet
requirements for reclassified Moderate, Serious and Severe ozone areas
``according to the schedules prescribed in connection with such
requirements, except that the Administrator may adjust any applicable
deadlines (other than attainment dates) to the extent such adjustment
is necessary or appropriate to assure consistency among the required
submissions.''
    The EPA notes that the notion embodied in this provision is
consistent with several other CAA provisions to establish a SIP
submission due date for an area that has failed to attain a NAAQS by
the relevant attainment date that may be shorter than the SIP
submission due date for the first plan due after an area is initially
designated as nonattainment.\46\ In this case, the areas that are being
reclassified to Serious are identifying and adopting RACT measures not
tied to attainment for a subset of sources emitting between 50-100 tpy
of VOC or NOX, because as Moderate areas they were already
required to address RACT and submit SIPs for sources emitting over 100
tpy. Therefore, the EPA does not agree with the commenter that it is
appropriate or necessary to extend the due date out to the July 2021
attainment date (which would be nearly 24 months) for submitting SIPs
addressing RACT measures not tied to attainment. The EPA is generally
in agreement with the commenter who stated that aligning deadlines
between submissions required for the 2015 ozone NAAQS and the 2008
ozone NAAQS addresses section 182(i)'s call for ``consistency among
submissions'' and creates efficiencies for states in preparing
submissions. However, a SIP revision submission due date of August 3,
2020, for RACT measures not tied to attainment would at this point
provide the states with less than 12 months from the effective date of
this final action to identify and evaluate such RACT, and prepare and
approve those RACT SIPs at the state level.
---------------------------------------------------------------------------

    \46\ For example, CAA section 179(d) requires a state that
failed to attain a NAAQS by the attainment date to submit a revised
implementation plan within 12 months of an EPA finding of failure to
attain. In addition, the requirements for PM10 and
PM2.5 nonattainment areas in CAA section 189(d) require a
Serious area to submit a revised implementation plan within 12
months of a failure to attain the standard.
---------------------------------------------------------------------------

    Finally, the EPA is cognizant and in agreement with the commenter
who stated that a due date of 18 months (which was the expected amount
of time the EPA anticipated with an August 3, 2020, due date) could
allow states to identify additional controls as ``reasonably
available'' in comparison with the shorter deadline.\47\ Therefore, the
EPA believes a due date 18-months from the effective date of this final
action for submission of certain RACT measures not tied to attainment
is appropriate.
---------------------------------------------------------------------------

    \47\ Moreover, the EPA notes that CAA section 110(k)(5), which
provides the EPA with authority to ``establish reasonable
deadlines'' for the submission of SIP revisions to address
substantial inadequacies in the SIP identified by the EPA, states
that the EPA may not establish such deadline ``to exceed 18 months
after the date of such notice.'' While this provision is not
directly applicable here, the EPA believes it is informative.
---------------------------------------------------------------------------

    3. Implementation deadline for RACT measures not tied to
attainment. The EPA proposed two options for the implementation
deadline for RACT measures not tied to attainment: (1) August 3, 2020
or (2) up through the full 5 years provided by the statute for RACT
implementation, i.e., January 1, 2024. In proposing the two dates, the
EPA made several observations. We noted at the time that ``[i]deally,
SIP submission deadlines would precede the implementation of control
strategies contained in those SIP submissions.'' \48\ We also noted, in
the context of taking comment on a providing a deadline past August 3,
2020, but no later than January 1, 2024, that additional time provided
for implementation of control measures ``could lead states to determine
that additional controls are reasonable, thus helping areas attain both
the 2008 and 2015 standards more expeditiously.'' Id. In particular, we
noted that in reclassifying areas from Marginal to Moderate in 2016 for
the 2008 ozone NAAQS after findings of failure to attain, states were
provided less than seven months to implement RACT. We acknowledged that
a more generous timeframe for implementing RACT may have allowed states
to adopt additional controls.
---------------------------------------------------------------------------

    \48\ See 83 FR 56781, November 14, 2018.
---------------------------------------------------------------------------

    Thus, the EPA is finalizing July 20, 2021, the Serious area
attainment date, as the deadline for implementation of RACT measures
not tied to attainment. Given the intervening time between proposed and
final rules, an August 3, 2020, deadline for implementation of RACT
measures not tied to attainment would limit the controls that states
could consider implementing. As noted

in the proposal, the EPA believes that there is a direct relationship
between the amount of time provided for implementation of RACT measures
not tied to attainment and the actual measures that will be available
to states to install or implement. We also continue to believe that a
slightly longer timeframe for measures that are not directly tied to
the area's attainment can be appropriate, especially where an area is
simultaneously implementing two ozone standards, such that additional
controls will help the area attain both standards more expeditiously.
On the other hand, the outside timeframe proposed by the EPA for
implementation of RACT measures not tied to attainment, January 1,
2024, was well beyond the Serious area attainment date and we received
feedback during the public comment period suggesting that any
implementation deadline beyond the attainment date would not serve
timely attainment. We are therefore finalizing July 20, 2021, the
Serious Area attainment date, as the deadline for implementing RACT
measures not needed for attainment. The EPA believes this date is
reasonable and appropriate when considering the comments received on
this issue and the timing of this final action. We also note that
because the EPA is finalizing the SIP submission date for RACT measures
not tied to attainment as 18 months from the effective date of this
final action, this implementation approach will provide at least some
window of time between the SIP revision submission due date and the
deadline for implementation of RACT measures not tied to attainment,
which, as we noted at proposal, is preferable to direct alignment of
the SIP submission due date and implementation deadline, where
possible.

IV. Environmental Justice Considerations

    The CAA requires that states with areas designated as nonattainment
submit to the Administrator the appropriate SIP revisions and implement
specified control measures by certain dates applicable to the area's
classification. By requiring additional planning and implementation
requirements for the seven nonattainment areas that the EPA determined
failed to attain the 2008 ozone NAAQS standards, the part of this
action reclassifying those seven areas from Moderate to Serious will
protect all those residing, working, attending school, or otherwise
present in those areas regardless of minority or economic status.

V. Statutory and Executive Order Reviews

A. Executive Order 12866: Regulatory Planning and Review and Executive
Order 13563: Improving Regulation and Regulatory Review

    This action is not a significant regulatory action and was
therefore not submitted to the Office of Management and Budget (OMB)
for review.

B. Executive Order 13771: Reducing Regulations and Controlling
Regulatory Costs

    This action is not an Executive Order 13771 regulatory action
because this action is not significant under Executive Order 12866.

C. Paperwork Reduction Act (PRA)

    This rule does not impose any new information collection burden
under the PRA not already approved by the Office of Management and
Budget.\49\ This action does not contain any information collection
activities and serves only to make final: (1) Determinations that
certain Moderate nonattainment areas listed in Table 2 attained the
2008 ozone standards by the July 20, 2018, attainment date; (2)
approval to grant certain Moderate nonattainment areas listed in Table
2 a 1-year attainment date extension from the July 20, 2018, attainment
date to July 20, 2019; (3) determinations that certain Moderate
nonattainment areas listed in Table 2 failed to attain the 2008 ozone
standards by the July 20, 2018, attainment date where such areas will
be reclassified as Serious nonattainment for the 2008 ozone standards
by operation of law upon the effective date of the final
reclassification action; and (4) establishment of adjusted due dates
for SIP revisions, including RACT SIP revisions, and RACT
implementation deadlines.
---------------------------------------------------------------------------

    \49\ On April 30, 2018, the OMB approved EPA's request for
renewal of the previously approved information collection request
(ICR). The renewed request expires on April 30, 2021, 3 years after
the approval date (see OMB Control Number 2060-0695 and ICR
Reference Number<PHONE_NUMBER>-003 for EPA ICR No. 2347.03).
---------------------------------------------------------------------------

D. Regulatory Flexibility Act (RFA)

    I certify that this action will not have a significant economic
impact on a substantial number of small entities under the RFA. This
action will not impose any requirements on small entities. The
determinations of attainment and failure to attain the 2008 ozone
standards (and resulting reclassifications), and the final approval to
grant 1-year attainment date extensions do not in and of themselves
create any new requirements beyond what is mandated by the CAA.
Instead, this rulemaking only makes factual determinations, and does
not directly regulate any entities.

E. Unfunded Mandates Reform Act (UMRA)

    This action does not contain any unfunded mandate as described in
UMRA, 2 U.S.C. 1531-1538,\50\ and does not significantly or uniquely
affect small governments. This action imposes no enforceable duty on
any state, local or tribal governments or the private sector.
---------------------------------------------------------------------------

    \50\ U.S.C. is United States Code.
---------------------------------------------------------------------------

F. Executive Order 13132: Federalism

    This action does not have federalism implications. It will not have
substantial direct effects on the states, on the relationship between
the national government and the states, or on the distribution of power
and responsibilities among the various levels of government.

G. Executive Order 13175: Consultation and Coordination With Indian
Tribal Governments

    This action has tribal implications. However, it will neither
impose substantial direct compliance costs on federally recognized
tribal governments, nor preempt tribal law. The EPA has identified a
few tribal areas that exist within certain Moderate nonattainment areas
for which the EPA is making final determinations of attainment for the
2008 ozone NAAQS. The EPA regional offices consulted with tribal
officials under the EPA policy on Consultation and Coordination with
Indian Tribes early in the process of developing this regulation to
permit them to have meaningful and timely input into its development.
Documentation of the consultation is provided in docket items EPA-HQ-
OAR-2018-0226-0041 and 0043.

H. Executive Order 13045: Protection of Children From Environmental
Health and Safety Risks

    The EPA interprets Executive Order 13045 as applying only to those
regulatory actions that concern environmental health or safety risks
that the EPA has reason to believe may disproportionately affect
children, per the definition of ``covered regulatory action'' in
section 2-202 of the Executive Order. This action is not subject to
Executive Order 13045 because it does not concern an environmental
health risk or safety risk.

I. Executive Order 13211: Actions That Significantly Affect Energy
Supply, Distribution, or Use

    This action is not subject to Executive Order 13211, because it is
not a significant regulatory action under Executive Order 12866.

J. National Technology Transfer Advancement Act (NTTAA)

    This rulemaking does not involve technical standards.

K. Executive Order 12898: Federal Actions To Address Environmental
Justice in Minority Populations and Low-Income Populations

    The EPA believes that this action does not have disproportionately
high and adverse human health or environmental effects on minority,
low-income populations and/or indigenous peoples, as specified in
Executive Order 12898 (59 FR 7629, February 16, 1994). The
documentation for this decision is contained in the section of the
preamble titled, ``Environmental Justice Considerations.''

L. Congressional Review Act (CRA)

    This rule is exempt from the CRA because it is a rule of particular
applicability. The rule makes factual determinations for specific
entities and does not directly regulate any entities. The
determinations of attainment and failure to attain the 2008 ozone NAAQS
(and resulting reclassifications), and the approval to grant 1-year
attainment date extensions do not in themselves create any new
requirements beyond what is mandated by the CAA.

M. Judicial Review

    Under section 307(b)(1) of the CAA, petitions for judicial review
of final actions that are locally and regionally applicable may be
filed only in the United States Court of Appeals for the appropriate
circuit. However, the statute also provides that notwithstanding that
general rule, ``a petition for review of any action . . . may be filed
only in the United States Court of Appeals for the District of Columbia
if such action is based on a determination of nationwide scope or
effect and if in taking such action the Administrator finds and
publishes that such action is based on such a determination.'' \51\
Because this final action makes findings regarding nonattainment areas
across the country, interprets the CAA and applies such interpretations
to states and nonattainment areas across the country, and establishes
SIP deadlines for newly reclassified areas in different states in a
consistent fashion, the Administrator finds that this action has
nationwide scope and effect. Therefore, in accordance with CAA section
307(b)(1), petitions for review of this final action may be filed only
in the United States Court of Appeals for the District of Columbia
Circuit by October 22, 2019. Note, under CAA section 307(b)(2), the
requirements established by this final rule may not be challenged
separately in any civil or criminal proceedings for enforcement.
