[EPA-R04-OAR-2022-0789; FRL-10888-03-R4]
Air Quality Designations; KY; Redesignation of the Kentucky
Portion of the Louisville, KY-IN 2015 8-Hour Ozone Nonattainment Area
to Attainment
AGENCY: Environmental Protection Agency (EPA).
ACTION: Proposed rule.
-----------------------------------------------------------------------
SUMMARY: The Environmental Protection Agency (EPA) is withdrawing its
proposed approval of the request to redesignate the Kentucky portion of
the Louisville, Kentucky-Indiana, 2015 8-hour ozone nonattainment area
(hereinafter referred to as the ``Louisville, KY-IN Area'' or ``Area'')
to attainment for the 2015 8-hour ozone National Ambient Air Quality
Standards (NAAQS or standards). EPA is withdrawing its April 18, 2023,
proposed approval and is now proposing to deny Kentucky's request to
redesignate the Kentucky portion of the Area from nonattainment to
attainment, based on the Area's violation of the NAAQS. EPA is taking
no action at this time on Kentucky's maintenance plan, including the
regional motor vehicle emission budgets for nitrogen oxides
(NOX) and volatile organic compounds (VOC) for the years of
2019 and 2035, submitted with Kentucky's redesignation request for the
Louisville, KY-IN Area. The redesignation request and maintenance plan
state implementation plan (SIP) revision were submitted by the
Commonwealth of Kentucky, through the Kentucky Energy and Environment
Cabinet (Cabinet), Division of Air Quality (DAQ), on September 6, 2022.
DATES: Comments must be received on or before February 3, 2025.

SUPPLEMENTARY INFORMATION:
I. Background
On September 6, 2022, Kentucky submitted a request to redesignate
the Kentucky portion of the Louisville, KY-IN 2015 8-hour ozone
nonattainment area from nonattainment to attainment. Accompanying
Kentucky's request for redesignation under Clean Air Act (CAA or Act)
section 107(d)(3)(D) was a SIP revision containing a maintenance plan
for the Area, as is required by CAA sections 107(d)(3)(E)(iv) and 175A
in order for EPA to redesignate an area from nonattainment to
attainment. On April 18, 2023, EPA proposed to take the following
separate but related actions addressing the September 6, 2022,
submittal: (1) to approve Kentucky's plan for maintaining the 2015
ozone NAAQS (maintenance plan), including the associated motor vehicle
emissions budgets (budgets) for the Louisville, KY-IN Area, and
incorporate the plan into the SIP, and (2) to redesignate the Kentucky
portion of the Area to attainment for the 2015 8-hour ozone NAAQS. EPA
also notified the public of the status of EPA's adequacy determination
for the budgets for the Area. The Louisville, KY-IN Area is composed of
Bullitt, Jefferson, and Oldham Counties in Kentucky, and Clark and
Floyd Counties in Indiana. These proposed actions are summarized below
and described in greater detail in the notice of proposed rulemaking
(NPRM) published on April 18, 2023. See 88 FR 23598.
II. Criteria for Redesignation
The CAA provides the requirements for redesignating a nonattainment
area to attainment. Specifically, section 107(d)(3)(E) of the CAA
prohibits the redesignation of such an area unless: (1) the EPA
Administrator determines that the area has attained the applicable
NAAQS; (2) the Administrator has fully approved the applicable
implementation plan for the area under section 110(k); (3) the
Administrator determines that the improvement in air quality is due to
permanent and enforceable reductions in emissions resulting from
implementation of the applicable SIP and applicable Federal air
pollutant control regulations and other permanent and enforceable
reductions; (4) the Administrator has fully approved a maintenance plan
for the area as meeting the requirements of section 175A; and (5) the
state containing such area has met all requirements applicable to the
area for purposes of redesignation under section 110 and part D of the
CAA.\1\
---------------------------------------------------------------------------
\1\ EPA provided guidance on redesignations in the General
Preamble for the Implementation of title I of the CAA Amendments of
1990 on April 16, 1992 (see 57 FR 13498) and supplemented that
guidance on April 28, 1992 (see 57 FR 18070). EPA has provided
further guidance on processing redesignation requests in the
following documents: 1. ``Ozone and Carbon Monoxide Design Value
Calculations,'' Memorandum from Bill Laxton, Director, Technical
Support Division, June 18, 1990; 2. ``Maintenance Plans for
Redesignation of Ozone and Carbon Monoxide Nonattainment Areas,''
Memorandum from G.T. Helms, Chief, Ozone/Carbon Monoxide Programs
Branch, April 30, 1992; 3. ``Contingency Measures for Ozone and
Carbon Monoxide (CO) Redesignations,'' Memorandum from G.T. Helms,
Chief, Ozone/Carbon Monoxide Programs Branch, June 1, 1992; 4.
``Procedures for Processing Requests to Redesignate Areas to
Attainment,'' Memorandum from John Calcagni, Director, Air Quality
Management Division, September 4, 1992 (hereinafter referred to as
the ``Calcagni Memorandum''); 5. ``State Implementation Plan (SIP)
Actions Submitted in Response to Clean Air Act (CAA) Deadlines,''
Memorandum from John Calcagni, Director, Air Quality Management
Division, October 28, 1992; 6. ``Technical Support Documents (TSDs)
for Redesignation of Ozone and Carbon Monoxide (CO) Nonattainment
Areas,'' Memorandum from G.T. Helms, Chief, Ozone/Carbon Monoxide
Programs Branch, August 17, 1993; 7. ``State Implementation Plan
(SIP) Requirements for Areas Submitting Requests for Redesignation
to Attainment of the Ozone and Carbon Monoxide (CO) National Ambient
Air Quality Standards (NAAQS) On or After November 15, 1992,''
Memorandum from Michael H. Shapiro, Acting Assistant Administrator
for Air and Radiation, September 17, 1993 (hereinafter referred to
as the ``Shapiro Memorandum''); 8. ``Use of Actual Emissions in
Maintenance Demonstrations for Ozone and CO Nonattainment Areas,''
Memorandum from D. Kent Berry, Acting Director, Air Quality
Management Division, November 30, 1993; 9. ``Part D New Source
Review (Part D NSR) Requirements for Areas Requesting Redesignation
to Attainment,'' Memorandum from Mary D. Nichols, Assistant
Administrator for Air and Radiation, October 14, 1994 (hereinafter
referred to as the ``Nichols Memorandum''); and 10. ``Reasonable
Further Progress, Attainment Demonstration, and Related Requirements
for Ozone Nonattainment Areas Meeting the Ozone National Ambient Air
Quality Standard,'' Memorandum from John S. Seitz, Director, Office
of Air Quality Planning and Standards, May 10, 1995.
---------------------------------------------------------------------------
[[Page 295]]
Regarding the first criterion's requirement that the area ``has
attained'' the relevant NAAQS, since the passage of the 1990 Amendments
to the CAA, EPA has consistently read that provision to require
continued attainment until EPA's action redesignating the area, and to
prohibit redesignation where an area violates the standard during the
pendency of the Agency's review of the state's request. See Calcagni
Memorandum at 5 (``Regions should advise States of the practical
planning consequences if EPA disapproves the redesignation request or
if the request is invalidated because of violations recorded during the
EPA's review.'') (emphasis added). The Agency's interpretation of that
provision is supported by the Act's definition of attainment and
nonattainment areas in CAA section 107(d)(1)(A), which defines a
nonattainment area as ``any area that does not meet'' the NAAQS (CAA
section 107(d)(1)(A)(i)) and an attainment area as ``any area that
meets'' the NAAQS. The use of the present tense in CAA section
107(d)(1)(A) is consistent with the use of the present perfect tense in
CAA section 107(d)(3)(E)(i), which tasks EPA with determining that an
area ``has attained'' the NAAQS, as opposed to attaining at some
previous time (e.g., ``had attained) with subsequent violations. See 62
FR 49154 (September 19, 1997) (laying out statutory analysis supporting
EPA's interpretation of CAA section 107(d)(3)(E)(i) in denial of the
Birmingham, AL 1-hour ozone redesignation request). EPA has applied
this interpretation of the first attainment redesignation criterion in
numerous redesignation actions.\2\
---------------------------------------------------------------------------
\2\ See, e.g., 59 FR 22757 (May 3, 1994) (denial of
redesignation request for Richmond, VA); 62 FR 49154 (September 19,
1997) (denial of redesignation request for Birmingham, AL); 61 FR
19193 (May 1, 1996) (denial of redesignation request for Pittsburgh-
Beaver Valley, PA); 61 FR 50718 (September 27, 1996) (denial of
redesignation request for the Kentucky portion of the Cincinnati-
Hamilton KY-OH area); 84 FR 16214 (April 18, 2019) (denial of
redesignation request for the Wisconsin portion of the Chicago-
Naperville, IL-IN-WI area).
---------------------------------------------------------------------------
Courts have confirmed EPA's interpretation of the first criterion
in cases with factually similar circumstances to those present here. In
Southwestern Pennsylvania Growth Alliance v. Browner, although denying
the petitioner's challenge based on their failure to preserve an issue
for litigation, the Third Circuit laid out its agreement with EPA's
reading of the provisions. See 121 F.3d 106 (3d Cir. 1997). Petitioners
there argued that EPA was not permitted to consider violations that
occurred after the submission of its redesignation request (and in that
case, violations that occurred after EPA's 18-month statutory window to
act on the state's request, per CAA section 107(d)(3)(D)). See id. at
111. The Court, in an opinion authored by then Judge Alito, wrote,
``[e]ven if we were to reach the merits of petitioner's argument, we
would hold that 42 U.S.C. 7407(d)(3)(D) did not preclude the EPA from
considering the summer 1995 exceedance data. The language of the
provision that enumerates the redesignation criteria tends to support
this result. Under 42 U.S.C. 7407(d)(3)(E)(i), the EPA Administrator
`may not' promulgate a redesignation of a nonattainment area unless,
among other things, `the Administrator determines that the area has
attained the [NAAQS]. The use of the term `has attained' instead of
`attained' may be interpreted as suggesting that the attainment must
continue until the date of the redesignation.'' Id. at 113. The Court
further stated that it did not agree with petitioners that the
mandatory window established by the Act for EPA to approve or deny a
state's redesignation request ``conclusively indicate[s] that Congress
intended to prohibit the EPA from taking action after the expiration of
the statutorily specified time period.'' Id. And finally, the Court
signaled its agreement with the Agency that continued fulfillment of
the first redesignation criterion is paramount to approving a state's
request: ``Since 42 U.S.C. 7407(d)(3)(E)(i) prohibits the EPA from
redesignating an area that is not in attainment of the NAAQS, the EPA
correctly denied Pennsylvania's request for redesignation. . . . An
area's failure to attain a NAAQS is the most fundamental criterion in
its designation as a nonattainment area.'' Id. at 118 n.5.
Similarly, the Sixth Circuit has interpreted the first
redesignation criterion consistent with the Third Circuit and with EPA.
In Commonwealth of Kentucky v. EPA, Kentucky argued that EPA should not
have denied its request to redesignate its portion of the Cincinnati-
Northern Kentucky OH-KY nonattainment area to attainment based on a
``single violation in July 1995'' when the area had measured clean data
in ``the period specified in the redesignation request, i.e., 1992-
1994.'' No. 96-4274, 1998 U.S. App. LEXIS 21686, at 5-6 (6th Cir. Sept.
2, 1998). Similar to the Petitioner's arguments in the Third Circuit
case discussed above, Kentucky asserted that ``Congress could have been
more clear if it had used the simple present tense (`attains') or the
progressive present tense (`is attaining') to explicitly require
continuing compliance.'' Id. at 9. But the Court, agreeing with EPA,
held that ``Congress also could have been more clear if it had used the
simple past tense (`attained') to require a noncontinuing compliance.
Congress declined both of these options and simply used the present
perfect tense (`has attained'). According to standard usage, the
present perfect tense denotes past action with an abiding effect or
continuing relevance. . . . Thus, the phrase `has attained,' as the
Third Circuit concluded, requires `that the attainment must continue
until the date of redesignation.' '' Id. (citation to Third Circuit
decision omitted). The Sixth Circuit bolstered its reading of the first
redesignation criterion by pointing to the Act's requirements regarding
maintenance. Id. at 10.
Significantly, in both cases where parties challenged EPA's
interpretation that the first redesignation criterion requires
continued attainment of the NAAQS through the Agency's final action
redesignating the area, the reviewing courts, ``after applying all
relevant interpretive tools, conclude[d]'' that EPA's reading was
``best.'' See Loper Bright Enterprises v. Raimondo, 144 S. Ct. 2244,
2266 (2024). The Third Circuit and the Sixth Circuit opinions
interpreting CAA section 107(d)(3)(E)(i) only cited Chevron deference
to the Agency as a backstop to their own examination of the text of the
provision and conclusion about the best reading of the Act's first
redesignation criterion. See SPGA v. Browner, 121 F.3d at 113; Kentucky
v. EPA, 1998 U.S. App. LEXIS 21686, at 11. Those courts' findings that
the CAA redesignation provision ``requires that the attainment must
continue until the date of redesignation'' was made in the course of
those courts ``do[ing] their ordinary job of interpreting statutes,''
``based on the traditional tools of statutory construction.'' See Loper
Bright, 144 S. Ct. at 2267-68.
III. Kentucky's Redesignation Request and SIP Revision
On April 18, 2023, EPA proposed to approve Kentucky's September 6,
2022, redesignation request and its maintenance plan SIP revision
based, in part, on complete, quality-assured, and certified 2019-2021
design values for
[[Page 296]]
each monitor in the Louisville, KY-IN Area.\3\ These design values are
equal to or less than the level of the 2015 8-hour ozone NAAQS and were
the most current design values at the time of proposal. See 88 FR
23598. Consistent with its longstanding interpretation of CAA section
107(d)(3)(E)(i), EPA stated in the NPRM that the Agency would not take
final action to approve the redesignation of the Kentucky portion of
the Louisville, KY-IN Area if the three-year design value for the Area
exceeded the NAAQS prior to EPA's finalization of the redesignation.
See 88 FR at 23601. Although preliminary 2022 ozone monitoring data at
the time of proposal indicated an attaining 2022 design value for the
Louisville, KY-IN Area,\4\ the complete, quality-assured, and certified
2021-2023 design value of 0.072 parts per million (ppm) exceeds the
NAAQS as discussed below.
---------------------------------------------------------------------------
\3\ EPA's full rationale for its proposed approval actions was
provided in the NPRM.
\4\ On February 21, 2022, Indiana submitted a separate
redesignation request and maintenance plan for its portion of the
Louisville, KY-IN Area. On July 5, 2022, EPA approved the
redesignation request and maintenance plan for the Indiana portion
of the Louisville, KY-IN Area. See 87 FR 39750.
---------------------------------------------------------------------------
IV. 2023 Violation of the NAAQS for Ozone in the Louisville, KY-IN Area
For ozone, an area may be considered to be attaining the 2015 8-
hour ozone NAAQS if it meets that standard, as determined in accordance
with 40 CFR 50.19 and Appendix U of 40 CFR part 50, based on three
complete, consecutive calendar years of quality-assured air quality
monitoring data. To attain the 2015 8-hour ozone NAAQS, the 3-year
average of the annual fourth-highest daily maximum 8-hour average ozone
concentrations measured at each monitor within an area must not exceed
0.070 ppm. Based on the data handling and reporting convention
described in 40 CFR part 50, Appendix U, the 2015 8-hour ozone NAAQS
are attained if the design value is 0.070 ppm or below. The data must
be collected and quality-assured in accordance with 40 CFR part 58 and
recorded in EPA's Air Quality System (AQS).
EPA reviewed complete, quality-assured, and certified ozone
monitoring data from monitoring stations in the Louisville, KY-IN Area
for the 2015 8-hour ozone NAAQS for 2021 through 2023, and the highest
3-year design value \5\ for 2021-2023 for the Louisville, KY-IN Area is
0.072 ppm, which exceeds the standard of 0.070 ppm.\6\ Further,
preliminary 2024 monitoring data indicates a 2022-2024 design value of
0.075 ppm for the Area. Therefore, the Louisville, KY-IN Area does not
meet the first statutory criterion for redesignation to attainment of
the 2015 8-hour ozone NAAQS found in section 107(d)(3)(E)(i) of the
CAA.
---------------------------------------------------------------------------
\5\ The design value for an area is the highest 3-year average
of the annual fourth-highest daily maximum 8-hour ozone
concentration recorded at any monitor in the area.
\6\ Final air quality design values for all criteria pollutants,
including ozone, are available at https://www.epa.gov/air-trends/air-quality-design-values. These design values are calculated in
accordance with 40 CFR part 50.
---------------------------------------------------------------------------
V. Public Comments Received on EPA's April 18, 2023, Proposal
EPA received three sets of adverse comments on the April 18, 2023,
NPRM. Commenters asserted that the Louisville, KY-IN Area did not
attain the 2015 ozone NAAQS with 2020-2022 data, expressed concern
regarding ambient air ozone exceedances, and stated that the reduction
in emissions in the Area were not permanent and enforceable. As EPA is
withdrawing its proposed approval of the redesignation request, the
comments on the earlier proposal are moot.
VI. Proposed Action
EPA is withdrawing its April 18, 2023, proposed approval of
Kentucky's request to redesignate the Kentucky portion of the
Louisville, KY-IN 2015 8-hour ozone nonattainment area to attainment
for the 2015 8-hour ozone NAAQS. For the reasons provided in this
notice, EPA is proposing to deny Kentucky's September 6, 2022,
redesignation request on the basis that the violations of the NAAQS
experienced in the Area during the pendency of EPA's review of the
request demonstrate that the Area has not met the first redesignation
criterion. EPA is not proposing to take action on the Commonwealth's
accompanying submissions to fulfill the other redesignation criteria,
given its proposed denial of the request based on air quality data.
VII. Statutory and Executive Order Reviews
Additional information about these statutes and Executive Orders
can be found at https://www.epa.gov/laws-regulations/laws-and-executive-orders.
A. Executive Order 12866: Regulatory Planning and Review and Executive
Order 14094: Modernizing Regulatory Review
This proposed action is not a significant regulatory action as
defined in Executive Order 12866, as amended by Executive Order 14094,
and is therefore not subject to a requirement for Executive Order 12866
review.
B. Paperwork Reduction Act (PRA)
This proposed action does not impose an information collection
burden under the PRA because it does not contain any information
collection activities.
C. Regulatory Flexibility Act (RFA)
I certify that this proposed 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 proposed action will not impose any
requirements on small entities because it merely proposes to deny a
redesignation request as not meeting Federal requirements.
D. Unfunded Mandates Reform Act (UMRA)
This proposed action does not contain an unfunded mandate as
described in UMRA, 2 U.S.C. 1531-1538, and does not significantly or
uniquely affect small governments. The proposed action imposes no
enforceable duty on any state, local or tribal governments or the
private sector.
E. Executive Order 13132: Federalism
This proposed 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.
F. Executive Order 13175: Consultation and Coordination With Indian
Tribal Governments
This proposed action does not have tribal implications, as
specified in Executive Order 13175, because the Area's SIP is not
approved to apply on any Indian reservation land or in any other area
where EPA or an Indian tribe has demonstrated that a tribe has
jurisdiction, and will not impose substantial direct costs on tribal
governments or preempt tribal law. Thus, Executive Order 13175 does not
apply to this proposed action.
G. Executive Order 13045: Protection of Children From Environmental
Health Risks and Safety Risks
EPA interprets Executive Order 13045 as applying only to those
regulatory actions that concern environmental health or safety risks
that EPA has reason to believe may disproportionately affect children,
per the definition of ``covered regulatory action'' in section 2-202 of
the Executive Order. Therefore, this
[[Page 297]]
proposed action is not subject to Executive Order 13045 because it
merely proposes to deny a redesignation request as not meeting Federal
requirements. Furthermore, EPA's Policy on Children's Health does not
apply to this proposed action.
H. Executive Order 13211: Actions Concerning Regulations That
Significantly Affect Energy Supply, Distribution, or Use
This proposed action is not subject to Executive Order 13211
because it is not a significant regulatory action under Executive Order
12866.
I. National Technology Transfer and Advancement Act (NTTAA)
This proposed action does not involve technical standards.
J. Executive Order 12898 and Executive Order 14096: Federal Actions To
Address Environmental Justice in Minority Populations and Low-Income
Populations and Revitalizing Our Nation's Commitment to Environmental
Justice for All
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 EJ concerns to the
greatest extent practicable and permitted by law. Executive Order 14096
(Revitalizing Our Nation's Commitment to Environmental Justice for All,
88 FR 25251, April 26, 2023) builds on and supplements E.O. 12898 and
defines EJ as among other things, the ``just treatment and meaningful
involvement of all people regardless of income, race, color, national
origin, or Tribal affiliation, or disability in agency decision-making
and other Federal activities that affect human health and the
environment.''
Neither the Cabinet nor the Louisville Metro Air Pollution Control
District evaluated EJ considerations as part of the Cabinet's
redesignation request; the CAA and applicable implementing regulations
neither prohibit nor require an evaluation. EPA did not perform an EJ
analysis and did not consider EJ in this proposed action. Consideration
of EJ is not required as part of this proposed action, and there is no
information in the record upon which this decision is based that is
inconsistent with the stated goal of Executive Order 12898/14096 of
achieving EJ for communities with EJ concerns.
