Abstract

The Environmental Protection Agency (EPA) is determining that the Missouri portion of the St. Louis, MO-IL bi-State nonattainment area failed to attain the 2015 ozone National Ambient Air Quality Standards (NAAQS) by the applicable attainment date. The effect of failing to attain by the applicable attainment date is that the area will be reclassified by operation of law to "Serious" nonattainment for the 2015 ozone NAAQS on December 31, 2024, the effective date of this final rule. This action fulfills the EPA's obligation under the Clean Air Act (CAA) to determine whether ozone nonattainment areas attained the NAAQS by the attainment date and to publish a document in the Federal Register identifying each area that is determined as having failed to attain and identifying the reclassification. The corresponding action for the Illinois portion of the St. Louis, MO-IL bi-State area is being taken separately.

Finding of Failure To Attain and Reclassification of the Missouri 
Portion of the St. Louis Nonattainment Area as Serious for the 2015 
Ozone National Ambient Air Quality Standards

AGENCY: Environmental Protection Agency (EPA).

ACTION: Final rule.

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

SUMMARY: The Environmental Protection Agency (EPA) is determining that 
the Missouri portion of the St. Louis, MO-IL bi-State nonattainment 
area failed to attain the 2015 ozone National Ambient Air Quality 
Standards (NAAQS) by the applicable attainment date. The effect of 
failing to attain by the applicable attainment date is that the area 
will be reclassified by operation of law to ``Serious'' nonattainment 
for the 2015 ozone NAAQS on December 31, 2024, the effective date of 
this final rule. This action fulfills the EPA's obligation under the 
Clean Air Act (CAA) to determine whether ozone nonattainment areas 
attained the NAAQS by the attainment date and to publish a document in 
the Federal Register identifying each area that is determined as having 
failed to attain and identifying the reclassification. The 
corresponding action for the Illinois portion of the St. Louis, MO-IL 
bi-State area is being taken separately.

DATES: This final rule is effective on December 31, 2024.

ADDRESSES: The EPA has established a docket for this action under 
Docket ID No. EPA-R07-OAR-2024-0540. All documents in the docket are

SUPPLEMENTARY INFORMATION:

I. Overview of Action

    The EPA is required to determine whether areas designated 
nonattainment for an ozone NAAQS attained the standard by the 
applicable attainment date, and to take certain steps for areas that 
failed to attain (see CAA section 181(b)(2)). The EPA's determination 
of attainment for the 2015 ozone NAAQS is based on a nonattainment 
area's design value (DV) as of the attainment date.\1\
---------------------------------------------------------------------------

    \1\ A DV is a statistic used to compare data collected at an 
ambient air quality monitoring site to the applicable NAAQS to 
determine compliance with the standard. The data handling 
conventions for calculating DVs for the 2015 ozone NAAQS are 
specified in appendix U to 40 CFR part 50. The DV for the 2015 ozone 
NAAQS is the 3-year average of the annual fourth highest daily 
maximum 8-hour average ozone concentration. The DV is calculated for 
each air quality monitor in an area, and the DV for an area is the 
highest DV among the individual monitoring sites located in the 
area.
---------------------------------------------------------------------------

    The 2015 ozone NAAQS is met at an EPA regulatory monitoring site 
when the DV does not exceed 0.070 parts per million (ppm). For the 
Moderate nonattainment areas for the 2015 ozone NAAQS addressed in this 
action, the attainment date was August 3, 2024. Because the DV is based 
on the three most recent, complete calendar years of data, attainment 
must occur no later than December 31 of the year prior to the 
attainment date (i.e., December 31, 2023, in the case of Moderate 
nonattainment areas for the 2015 ozone NAAQS). As such, the EPA's 
determinations for each area are based upon the complete, quality-
assured, and certified ozone monitoring data from calendar years 2021, 
2022, and 2023.
    This action addresses the Missouri portion of the St. Louis bi-
State nonattainment area (hereafter St. Louis area) that was classified 
as Moderate for the 2015 ozone NAAQS as of the Moderate area attainment 
date of August 3, 2024. Table 1 provides a summary of the DVs and the 
EPA's air quality-based determinations for the St. Louis area.

    Table 1--Summary of Nonattainment Areas in Missouri Classified as
                    Moderate for the 2015 Ozone NAAQS
------------------------------------------------------------------------
                                   2021-2023 design    Attainment by the
      Nonattainment  area          value (DV)  (ppm)    attainment  date
------------------------------------------------------------------------
St. Louis......................                 0.074  Failed to attain.
------------------------------------------------------------------------

    The EPA is finding that the St. Louis area as shown in table 1 did 
not attain by the attainment date, because the 2021-2023 DVs are 
greater than 0.070 ppm. If the EPA determines that a nonattainment area 
classified as Moderate failed to attain by the attainment date, CAA 
section 181(b)(2)(B) requires the EPA to publish a document in the 
Federal Register, no later than 6 months following the attainment date, 
identifying each such area and identifying the applicable 
reclassification.
    Under CAA section 181(b)(2)(A), the effect of this determination is 
that the St. Louis area will be reclassified by operation of law as 
Serious on the effective date of this final rule. The reclassified area 
will then be subject to the Serious area requirement to attain the 2015 
ozone NAAQS as expeditiously as practicable, but not later than August 
3, 2027.
    Upon reclassification, stationary air pollution sources in the St. 
Louis ozone nonattainment areas will be subject to Serious ozone 
nonattainment area New Source Review (NSR) and title V permit 
requirements. The source applicability thresholds for major sources and 
major source modification emissions will be 50 tons per year (tpy) for 
volatile organic compounds (VOC) and nitrogen oxides (NO<INF>X</INF>). 
For new and modified major stationary sources subject to review under 
Missouri regulation 10 CSR 10-6.060, in the EPA approved State 
implementation plan (SIP),\2\ VOC and NO<INF>X</INF> emission increases 
from the proposed construction of the new or modified major stationary 
sources must be offset by emission reductions by a minimum offset ratio 
of 1.20 to 1 (see CAA section 182(c)(10)).
---------------------------------------------------------------------------

    \2\ Specifically, we are referring to the EPA-approved Missouri 
regulation 10 Code of State Regulations (CSR) 10-6.060, titled 
``Construction Permits Required.'' Most recently revised and 
approved into Missouri's SIP on August 11, 2022 (85 FR 49530).
---------------------------------------------------------------------------

    Once reclassified as Serious, Missouri must submit to the EPA the 
SIP revisions for this area that satisfies the statutory and regulatory 
requirements applicable to Serious areas established in CAA section 
182(c) and in the 2015 Ozone NAAQS SIP Requirements Rule (see 83 FR 
62998, December 6, 2018). The EPA is establishing deadlines for 
submitting SIP revisions for newly reclassified areas in a separate 
action.

II. What is the background for this action?

    On October 26, 2015, the EPA issued its final action to revise the 
NAAQS for ozone to establish a new 8-hour standard (see 80 FR 65452, 
October 26, 2015). In that action, the EPA promulgated identical 
tighter primary and secondary ozone standards designed to protect 
public health and welfare that specified an 8-hour ozone level of 0.070 
ppm. Specifically, the standards require that the 3-year average of the 
annual fourth highest daily maximum 8-hour average ozone concentration 
may not exceed 0.070 ppm.
    Effective on August 3, 2018, the EPA designated 52 areas throughout 
the country as nonattainment for the 2015 ozone NAAQS (see 83 FR 25776, 
June 4, 2018). As part of that action, the EPA designated the St. 
Louis, MO-IL bi-State area as Marginal nonattainment for the 2015 Ozone 
NAAQS. The area included Boles Township of Franklin County, St. Charles 
County, St. Louis County, and St. Louis City in Missouri, and Madison 
and St. Clair Counties in Illinois. As part of that same action, EPA 
designated Jefferson County and the remaining portion of Franklin 
County, in Missouri, and Monroe County in Illinois, as attainment/
unclassifiable. On July 10, 2020, the District of Columbia Circuit 
Court remanded the Jefferson County, Missouri, and Monroe County, 
Illinois, designations (among other designations) to the EPA. The Court 
upheld EPA's designation of Boles Township as nonattainment and the 
remainder of Franklin County as attainment/unclassifiable. In response 
to the Court remand, the EPA revised the Jefferson County, Missouri, 
and Monroe County, Illinois, designation to nonattainment on May 26, 
2021 (86 FR 31438).
    In a separate action, the EPA assigned classification thresholds 
and attainment dates based on the severity of an area's ozone problem, 
determined by the area's DV (see 83 FR 10376, May 8, 2018). The EPA 
established the attainment date for Marginal, Moderate, and Serious 
nonattainment areas as 3 years, 6 years, and 9 years, respectively, 
from the effective date of the final designations.

[[Page 92818]]

Thus, the attainment date for Marginal nonattainment areas for the 2015 
ozone NAAQS was August 3, 2021, the attainment date for Moderate areas 
was August 3, 2024, and the attainment date for Serious areas is August 
3, 2027. On October 7, 2022 (87 FR 60897), the EPA determined that 22 
areas, including the St. Louis area addressed in this action, did not 
attain the standards by the Marginal attainment date, and was 
reclassified as Moderate by operation of law.

III. What is the statutory authority for this action?

    The statutory authority for this determination is provided by the 
CAA, as amended (42 U.S.C. 7401 et seq.). Relevant portions of the CAA 
include, but are not necessarily limited to, sections 181 and 182.
    CAA section 107(d) provides that when the EPA establishes or 
revises a NAAQS, the agency must designate areas of the country as 
nonattainment, attainment, or unclassifiable based on whether an area 
is not meeting (or is contributing to air quality in a nearby area that 
is not meeting) the NAAQS, meeting the NAAQS, or cannot be classified 
as meeting or not meeting the NAAQS, respectively. Subpart 2 of part D 
of title I of the CAA governs the classification, state planning, and 
emissions control requirements for any areas designated as 
nonattainment for a revised primary ozone NAAQS. In particular, CAA 
section 181(a)(1) requires each area designated as nonattainment for a 
revised ozone NAAQS to be classified at the same time as the area is 
designated based on the extent of the ozone problem in the area (as 
determined based on the area's DV). Classifications for ozone 
nonattainment areas are ``Marginal,'' ``Moderate,'' ``Serious,'' 
``Severe,'' and ``Extreme,'' in order of stringency. CAA section 182 
provides the specific attainment planning and additional requirements 
that apply to each ozone nonattainment area based on its 
classification.
    Section 181(b)(2)(A) of the CAA requires that within 6 months 
following the applicable attainment date, the EPA shall determine 
whether an ozone nonattainment area attained the ozone standard based 
on the area's DV as of that date. Under CAA section 181(a)(5) as 
interpreted by the EPA in 40 CFR 51.1307, upon application by any 
state, the EPA may grant a 1-year extension to the attainment date when 
certain criteria are met. One criterion for a first attainment date 
extension is that an area's fourth highest daily maximum 8-hour value 
for the attainment year must not exceed the level of the standard.
    In the event an area fails to attain the ozone NAAQS by the 
applicable attainment date and is not granted a 1-year attainment date 
extension, CAA section 181(b)(2)(A) requires the EPA to make the 
determination that an ozone nonattainment area failed to attain the 
ozone standard by the applicable attainment date, and requires the area 
to be reclassified by operation of law to the higher of: (1) The next 
higher classification for the area, or (2) the classification 
applicable to the area's DV as of the determination of failure to 
attain.\3\ Section 181(b)(2)(B) of the CAA requires the EPA to publish 
the determination of failure to attain and accompanying 
reclassification in the Federal Register no later than 6 months after 
the attainment date, which in the case of the Moderate nonattainment 
areas considered in this determination is February 3, 2025.
---------------------------------------------------------------------------

    \3\ All nonattainment areas named in this action that failed to 
attain by the attainment date would be classified to the next higher 
classification, Serious. None of the affected areas has a DV that 
would otherwise place an area in a higher classification.
---------------------------------------------------------------------------

    Once an area is reclassified, each state that contains a 
reclassified area is required to submit certain SIP revisions in 
accordance with its more stringent classification. The SIP revisions 
are intended to, among other things, demonstrate how the area will 
attain the NAAQS as expeditiously as practicable, but no later than 
August 3, 2027, the Serious area attainment date for the 2015 ozone 
NAAQS. Per CAA section 182(i), a state with a reclassified ozone 
nonattainment area must submit the applicable attainment plan 
requirements ``according to the schedules prescribed in connection with 
such requirements'' in CAA section 182(c) for Serious areas, but the 
EPA ``may adjust applicable deadlines (other than attainment dates) to 
the extent such adjustment is necessary or appropriate to assure 
consistency among the required submissions.'' The EPA is addressing the 
SIP revision and implementation deadlines for newly reclassified 
Serious areas, as well as the continued applicability of Moderate area 
requirements if they have not yet been met, in a separate rulemaking.

IV. How does the EPA determine whether an area has attained the 
standard?

    The level of the 2015 ozone NAAQS is 0.070 ppm.\4\ Under the EPA 
regulations at 40 CFR part 50, appendix U, the 2015 ozone NAAQS is 
attained at a site when the 3-year average of the annual fourth highest 
daily maximum 8-hour average ambient ozone concentration (i.e., DV) 
does not exceed 0.070 ppm. When the DV does not exceed 0.070 ppm at 
each ambient air quality monitoring site within the area, the area is 
deemed to be attaining the ozone NAAQS. Each area's DV is determined by 
the highest DV among monitors with valid DVs.\5\ The data handling 
convention in appendix P dictates that concentrations shall be reported 
in ``ppm'' to the third decimal place, with additional digits to the 
right being truncated. Thus, a computed 3-year average ozone 
concentration of 0.071 ppm is greater than 0.070 ppm and would exceed 
the standard, but a computed 3-year average ozone concentration of 
0.0709 ppm is truncated to 0.070 ppm and attains the 2015 ozone NAAQS.
---------------------------------------------------------------------------

    \4\ See 40 CFR 50.19.
    \5\ According to appendix U to 40 CFR part 50, ambient 
monitoring sites with a DV of 0.070 ppm or less must meet minimum 
data completeness requirements in order to be considered valid. 
These requirements are met for a 3-year period at a site if daily 
maximum 8-hour average ozone concentrations are available for at 
least 90% of the days within the ozone monitoring season, on 
average, for the 3-year period, with a minimum of at least 75% of 
the days within the ozone monitoring season in any one year. Ozone 
monitoring seasons are defined for each State in appendix D to 40 
CFR part 58. DVs greater than 0.070 ppm are considered to be valid 
regardless of the data completeness.
---------------------------------------------------------------------------

    The EPA's determination of attainment is based upon hourly ozone 
concentration data for calendar years 2021, 2022, and 2023 that have 
been collected and quality-assured in accordance with 40 CFR part 58 
and reported to the EPA's Air Quality System (AQS) database.\6\
---------------------------------------------------------------------------

    \6\ The EPA maintains the AQS, a database that contains ambient 
air pollution data collected by the EPA, state, local, and Tribal 
air pollution control agencies. The AQS also contains meteorological 
data, descriptive information about each monitoring station 
(including its geographic location and its operator) and data 
quality assurance/quality control information. The AQS data is used 
to (1) assess air quality, (2) assist in attainment/non-attainment 
designations, (3) evaluate SIPs for non-attainment areas, (4) 
perform modeling for permit review analysis, and (5) prepare reports 
for Congress as mandated by the CAA. Access is through the website 
at <a href="https://www.epa.gov/aqs">https://www.epa.gov/aqs</a>.
---------------------------------------------------------------------------

    State and local monitoring network plans are subject to approval by 
the EPA on an annual basis and any interim modifications to those plans 
must also be approved by the EPA.\7\ The annual monitoring network plan 
process is provided in 40 CFR 58.10 and the requirements governing 
system modifications and monitor discontinuations are laid out in 40 
CFR 58.14. Where state or local agencies seek to modify the ambient air 
quality

[[Page 92819]]

monitoring networks by discontinuing a monitor station, the EPA may 
approve such modifications subject to the criteria established in 40 
CFR 58.14(c). The EPA may not approve such discontinuation if doing so 
would compromise data collection needed for implementation of a NAAQS. 
If a monitor has been discontinued subject to 40 CFR 58.14 such that 
the discontinuation results in insufficient data to calculate a valid 
DV according to appendix U to 40 CFR part 50, the EPA will determine 
the applicable area's attainment status based on the remaining monitors 
in the area.

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

V. What is the EPA's determination for the area?

    The EPA is determining that the St. Louis Moderate nonattainment 
area addressed in this action failed to attain the 2015 ozone NAAQS by 
the attainment date of August 3, 2024. As shown in table 1, at least 
one monitor in this area had a 2021-2023 DV greater than 0.070 ppm. The 
EPA has further determined that the St. Louis area did not meet the 
requirement under section 181(a)(5)(B) and 40 CFR 51.1307 necessary to 
grant a 1-year extension of the attainment date, because at least one 
monitor in the area had a 2023 fourth highest daily maximum 8-hour 
average that was greater than 0.070 ppm. Table 2 shows the annual 
fourth highest daily maximum 8-hour average ozone concentration and 
2021-2023 DV for each monitor in the St. Louis, MO-IL area.

VI. What action is the EPA taking?

    Pursuant to CAA section 181(b)(2), the EPA is determining that the 
St. Louis area failed to attain the 2015 ozone NAAQS by the applicable 
attainment date of August 3, 2024. Therefore, upon the effective date 
of this final action, the area will be reclassified, by operation of 
law, to Serious for the 2015 ozone NAAQS. Once reclassified as Serious, 
the area 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 August 3, 
2027.
    Section 553 of the Administrative Procedure Act, 5 U.S.C. 
553(b)(B), provides that, when an agency for good cause finds that 
notice and public procedures are impracticable, unnecessary or contrary 
to the public interest, the agency may issue a rule without providing 
notice and an opportunity for public comment. The EPA has determined 
that there is good cause for making this final agency action without 
prior proposal and opportunity for comment because our action to 
determine whether this area has attained the NAAQS by the attainment 
date is governed, per CAA section 181(b)(2)(A), solely by area design 
values as of that date. The area design values relied upon in this 
document are calculations based on the certified air quality monitoring 
data governed by EPA's regulations and involve no judgment or 
discretion. Thus, notice and public procedures are unnecessary to take 
this action. The EPA finds that this constitutes good cause under 5 
U.S.C. 553(b)(B).

Order 14094: Modernizing Regulatory Review

    This action is not a ``significant regulatory action'' under the 
terms of Executive Order 12866 (58 FR 51735, October 4, 1993) and is 
therefore not subject to review under Executive Order 14094 (88 FR 
21879, April 11, 2023).

B. Paperwork Reduction Act (PRA)

    This rule does not impose an information collection burden under 
the provisions of the PRA of 1995 (44 U.S.C. 3501 et seq.). This action 
does not contain any information collection activities and serves only 
to make a final determination that the St. Louis nonattainment area 
failed to attain the 2015 ozone standards by the August 3, 2024, 
attainment date where such area will be reclassified as Serious 
nonattainment for the 2015 ozone standards by operation of law upon the 
effective date of the final reclassification action.

C. 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 (5 
U.S.C. 601 et seq.). This action will not impose any requirements on 
small entities. The determination of failure to attain the 2015 ozone 
standards (and resulting reclassifications), do not in and of 
themselves create any new requirements beyond what is mandated by the 
CAA. This final action would require the State to adopt and submit SIP 
revisions to satisfy CAA requirements and would not itself directly 
regulate any small entities.

D. Unfunded Mandates Reform Act (UMRA)

    This action does not contain any unfunded mandate as described in 
UMRA, 2 U.S.C. 1531-1538 and does not significantly or uniquely affect 
small governments. The action imposes no

[[Page 92820]]

enforceable duty on any state, local, or Tribal governments or the 
private sector.

E. 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. The 
division of responsibility between the Federal Government and the 
States for purposes of implementing the NAAQS is established under the 
CAA.

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

    Executive Order 13175 (65 FR 67249, November 9, 2000), requires the 
EPA to develop an accountable process to ensure ``meaningful and timely 
input by Tribal officials in the development of regulatory policies 
that have Tribal implications.'' This action does not have Tribal 
implications as specified in Executive Order 13175. This action does 
not apply on any Indian reservation land, any other area where EPA or 
an Indian Tribe has demonstrated that a Tribe has jurisdiction, or non-
reservation areas of Indian country. Thus, Executive Order 13175 does 
not apply to this action.

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

    The EPA interprets Executive Order 13045 (62 FR 19885, April 23, 
1997) as applying 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 
establish an environmental standard intended to mitigate health or 
safety risks.

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

    This action is not subject to Executive Order 13211 (66 FR 28355, 
May 22, 2001) because it is not a significant regulatory action under 
Executive Order 12866.

I. National Technology Transfer and Advancement Act (NTTAA)

    This rulemaking does not involve technical standards. Therefore, 
the EPA is not considering the use of any voluntary consensus 
standards.

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

    Executive Order 12898 (Federal Actions To Address Environmental 
Justice in Minority Populations and Low-Income Populations, 59 FR 7629, 
February 16, 1994) directs Federal agencies to identify and address 
``disproportionately high and adverse human health or environmental 
effects'' of their actions on communities with environmental justice 
(EJ) concerns to the greatest extent practicable and permitted by law. 
The EPA defines EJ as ``the fair treatment and meaningful involvement 
of all people regardless of race, color, national origin, or income 
with respect to the development, implementation, and enforcement of 
environmental laws, regulations, and policies.'' The EPA further 
defines the term fair treatment to mean that ``no group of people 
should bear a disproportionate burden of environmental harms and risks, 
including those resulting from the negative environmental consequences 
of industrial, governmental, and commercial operations or programs and 
policies.''
    The EPA did not perform an EJ analysis and did not consider EJ in 
this action. Due to the nature of the action being taken here, this 
action is expected to have a neutral to positive impact on the air 
quality of the affected area. Consideration of EJ is not required as 
part of this action, and there is no information in the record 
inconsistent with the stated goal of E.O. 12898 of achieving 
environmental justice for communities with EJ concerns.

K. Congressional Review Act (CRA)

    This rule is exempt from the CRA because it is a rule of particular 
applicability. The rule makes a factual determination for an identified 
entity, the St. Louis area, based on facts and circumstances specific 
to that entity. The determinations of attainment and failure to attain 
the 2015 ozone NAAQS do not in themselves create any new requirements 
beyond what is mandated by the CAA.

L. 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 January 24, 2025. Filing a petition for 
reconsideration by the Administrator of this action 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 this action. This 
action may not be challenged later in proceedings to enforce its 
requirements. (See section 307(b)(2).)

\1\ Includes any Indian country in each county or area, unless otherwise specified. The EPA is not determining the boundaries of any area of Indian
  country in this table, including any area of Indian country located in the larger designation area. The inclusion of any Indian country in the
  designation area is not a determination that the state has regulatory authority under the Clean Air Act for such Indian country.
\2\ This date is August 3, 2018, unless otherwise noted.
\3\ EPA revised the nonattainment boundary in response to a court decision, which did not vacate any designations for the 2015 ozone NAAQS, but which
  remanded the designation for the identified county. Because this additional area is part of a previously designated nonattainment area, the
  implementation dates for the overall nonattainment area (e.g., the August 3, 2021 attainment date) remain unchanged regardless of this later
  designation date.
