Air Plan Approval; Kentucky; Infrastructure Requirements for the 
2015 8-Hour Ozone National Ambient Air Quality Standard

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule.

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

SUMMARY: The Environmental Protection Agency (EPA) is proposing to 
approve portions of the State Implementation Plan (SIP) submission, 
provided by the Commonwealth of Kentucky, Energy and Environment 
Cabinet, Department for Environmental Protection, through the Kentucky 
Division for Air Quality (KDAQ), on January 9, 2019, to demonstrate 
that the Commonwealth meets the infrastructure requirements of the 
Clean Air Act (CAA or Act) for the 2015 8-hour ozone national ambient 
air quality standard (NAAQS). Whenever EPA promulgates a new or revised 
NAAQS, the CAA requires that each state adopt and submit a SIP for the 
implementation, maintenance and enforcement of each such NAAQS. KDAQ 
certified that the Kentucky SIP contains provisions that ensure the 
2015 8-hour ozone NAAQS is implemented, enforced, and maintained in 
Kentucky.

SUPPLEMENTARY INFORMATION:

I. Background

    On October 1, 2015, (published on October 26, 2015 (80 FR 65292)), 
EPA promulgated a revised primary and secondary NAAQS for ozone 
revising the 8-hour ozone NAAQS from 0.075 parts per million (ppm) to a 
new more protective level of 0.070 ppm. Pursuant to section 110(a)(1) 
of the CAA, states are required to submit SIP revisions meeting the 
applicable requirements of section 110(a)(2) within three years after 
promulgation of a new or revised NAAQS or within such shorter period as 
EPA may prescribe. Section 110(a)(2) requires states to address basic 
SIP elements such as requirements for monitoring, basic program 
requirements and legal authority that are designed to assure attainment 
and maintenance of the NAAQS. This particular type of SIP is commonly 
referred to as an ``infrastructure SIP.'' States were required to 
submit such SIPs for the 2015 8-hour ozone NAAQS to EPA no later than 
October 1, 2018.\1\
---------------------------------------------------------------------------

    \1\ In these infrastructure SIP submissions States generally 
certify evidence of compliance with sections 110(a)(1) and (2) of 
the CAA through a combination of state regulations and statutes, 
some of which have been incorporated into the federally-approved 
SIP. In addition, certain federally-approved, non-SIP regulations 
may also be appropriate for demonstrating compliance with sections 
110(a)(1) and (2).
---------------------------------------------------------------------------

    This rulemaking is proposing to approve portions of Kentucky's 
January 9, 2019, ozone infrastructure SIP submission for the applicable 
requirements of the 2015 8-hour ozone NAAQS, with the exception of the 
interstate transport provisions of section 110(a)(2)(D)(i)(I) 
pertaining to contribution to nonattainment or interference with 
maintenance in other states; the prevention of significant 
deterioration (PSD) provisions related to major sources under sections 
110(a)(2)(C), 110(a)(2)(D)(i)(II), and 110(a)(2)(J); and air quality 
modeling and submission of modeling data under sections 110(a)(2)(K). 
With respect to the interstate transport provisions of section 
110(a)(2)(D)(i)(I), the PSD provisions related to major sources under 
sections 110(a)(2)(C), 110(a)(2)(D)(i)(II), and 110(a)(2)(J), and the 
air quality modeling provisions under section 110(a)(2)(K), EPA will 
address these in separate rulemaking actions.

II. What elements are required under sections 110(a)(1) and (2)?

    Section 110(a) of the CAA requires states to submit SIPs to provide 
for the implementation, maintenance, and enforcement of a new or 
revised NAAQS within three years following the promulgation of such 
NAAQS, or within such shorter period as EPA may prescribe. Section 
110(a) imposes the obligation upon states to make a SIP submission to 
EPA for a new or revised NAAQS, but the contents of that submission may 
vary depending upon the facts and circumstances. In particular, the 
data and analytical tools available at the time the state develops and 
submits the SIP for a new or revised NAAQS affects the content of the 
submission. The contents of such SIP submissions may also vary 
depending upon what provisions the state's existing SIP already 
contains.\2\
---------------------------------------------------------------------------

    \2\ Throughout this rulemaking, unless otherwise indicated, the 
term ``Kentucky Administrative Regulations'' or ``KAR'' indicates 
that the cited regulation has been approved into Kentucky's 
federally-approved SIP. The term ``KRS'' indicates cited Kentucky 
Revised Statutes, which govern the Commonwealth of Kentucky and are 
not a part of the SIP unless otherwise indicated.
---------------------------------------------------------------------------

    More specifically, section 110(a)(1) provides the procedural and 
timing requirements for SIPs. Section 110(a)(2) lists specific elements 
that states must meet for ``infrastructure'' SIP requirements related 
to a newly established or revised NAAQS. As mentioned above, these 
requirements include basic SIP elements such as requirements for 
monitoring, basic program requirements and legal authority that are 
designed to assure attainment and maintenance of the NAAQS. The 
requirements of Section 110(a)(2) are listed below and summarized in 
Section IV, and in EPA's September 13, 2013, memorandum entitled 
``Guidance on Infrastructure State Implementation Plan (SIP) Elements 
under Clean Air Act Sections 110(a)(1) and 110(a)(2).'' \3\
---------------------------------------------------------------------------

    \3\ Two elements identified in section 110(a)(2) are not 
governed by the three-year submission deadline of section 110(a)(1) 
because SIPs incorporating necessary local nonattainment area 
controls are not due within three years after promulgation of a new 
or revised NAAQS, but rather are due at the time the nonattainment 
area plan requirements are due pursuant to section 172. These 
requirements are: (1) Submissions required by section 110(a)(2)(C) 
to the extent that subsection refers to a permit program as required 
in part D, title I of the CAA; and (2) submissions required by 
section 110(a)(2)(I) which pertain to the nonattainment planning 
requirements of part D, title I of the CAA. This proposed rulemaking 
does not address infrastructure elements related to section 
110(a)(2)(I) or the Part D nonattainment permitting requirements of 
110(a)(2)(C).

     110(a)(2)(A): Emission Limits and Other Control Measures
     110(a)(2)(B): Ambient Air Quality Monitoring/Data System
     110(a)(2)(C): Programs for Enforcement of Control Measures 
and for Construction or Modification of Stationary Sources \4\
---------------------------------------------------------------------------

    \4\ As mentioned above, the Part D permit program for 
construction and modification of stationary sources is not relevant 
to this proposed rulemaking.
---------------------------------------------------------------------------

     110(a)(2)(D)(i)(I) and (II): Interstate Pollution 
Transport
     110(a)(2)(D)(ii): Interstate Pollution Abatement and 
International Air Pollution
     110(a)(2)(E): Adequate Resources and Authority, Conflict 
of Interest, and Oversight of Local Governments and Regional Agencies
     110(a)(2)(F): Stationary Source Monitoring and Reporting
     110(a)(2)(G): Emergency Powers
     110(a)(2)(H): SIP Revisions
     110(a)(2)(I): Plan Revisions for Nonattainment Areas \5\
---------------------------------------------------------------------------

    \5\ As also mentioned above, this element is not relevant to 
this proposed rulemaking.
---------------------------------------------------------------------------

     110(a)(2)(J): Consultation with Government Officials, 
Public

     110(a)(2)(M): Consultation and Participation by Affected 
Local Entities

III. What is EPA's approach to the review of infrastructure SIP 
submissions?

    EPA is acting upon the SIP submission from Kentucky that addresses 
certain infrastructure requirements of CAA sections 110(a)(1) and 
110(a)(2) for the 2015 8-hour ozone NAAQS. Whenever EPA promulgates a 
new or revised NAAQS, CAA section 110(a)(1) requires states to make SIP 
submissions to provide for the implementation, maintenance, and 
enforcement of the NAAQS, commonly referred to as an ``infrastructure 
SIP.'' These submissions must meet the various requirements of CAA 
section 110(a)(2), as applicable. Due to ambiguity in some of the 
language of CAA section 110(a)(2), EPA believes that it is appropriate 
to interpret these provisions in the specific context of acting on 
infrastructure SIP submissions. EPA has previously provided 
comprehensive guidance on the application of these provisions through a 
guidance document for infrastructure SIP submissions and through 
regional actions on infrastructure submissions.\6\ Unless otherwise 
noted below, we are following that existing approach in acting on this 
submission. In addition, in the context of acting on such 
infrastructure submissions, EPA evaluates the submitting state's SIP 
for facial compliance with statutory and regulatory requirements, not 
for the state's implementation of its SIP.\7\ EPA has other authority 
to address any issues concerning a state's implementation of the rules, 
regulations, consent orders, etc. that comprise its SIP.
---------------------------------------------------------------------------

    \6\ EPA explains and elaborates on these ambiguities and its 
approach to address them in its September 13, 2013 Infrastructure 
SIP Guidance (available at https://www3.epa.gov/airquality/urbanair/sipstatus/docs/Guidance_on_Infrastructure_SIP_Elements_Multipollutant_FINAL_Sept_2013.pdf), as well as in numerous agency actions, including EPA's prior 
action on Kentucky's infrastructure SIP to address the 2010 Nitrogen 
Dioxide NAAQS. (81 FR 41488 (June 27, 2016)).
    \7\ See Mont. Envtl. Info. Ctr. v. Thomas, 902 F.3d 971 (9th 
Cir. 2018).
---------------------------------------------------------------------------

IV. What is EPA's analysis of how Kentucky addressed the elements of 
the sections 110(a)(1) and (2) ``Infrastructure'' provisions?

    Kentucky's January 9, 2019 infrastructure submission addresses the 
provisions of sections 110(a)(1) and (2) as described below.
    1. 110(a)(2)(A) Emission Limits and Other Control Measures: Section 
110(a)(2)(A) requires that each implementation plan include enforceable 
emission limitations and other control measures, means, or techniques 
(including economic incentives such as fees, marketable permits, and 
auctions of emissions rights), as well as schedules and timetables for 
compliance, as may be necessary or appropriate to meet the applicable 
requirements.
    Kentucky's submission cites to numerous SIP-approved regulations 
that include enforceable emission limits and other control measures 
found in 401 Kentucky Administrative Regulations (KAR) Chapters 50-53, 
59, 61, 63, and 65 to demonstrate that the Commonwealth meets the 
requirements of this element, including the following:

    Collectively these regulations establish enforceable emissions 
limitations and other control measures, means or techniques, for 
activities that contribute to ozone concentrations in the ambient air 
and provide authority to establish such limits and measures as well as 
schedules for compliance to meet the applicable requirements of the 
CAA. In addition, Kentucky Revised Statute (KRS) Chapter 224 Section 
10-100 (KRS 224.10-100), provides the Energy and Environment Cabinet 
the authority to administer all rules, regulations, and orders 
promulgated under Chapter 224, and to provide for the prevention, 
abatement, and control of all water, land, and air pollution.
    EPA has made the preliminary determination that the provisions 
contained in these regulations, and Kentucky's statute are adequate for 
enforceable emission limitations and other control measures, means, or 
techniques, as well as schedules and timetables for compliance for the 
2015 8-hour ozone NAAQS in the Commonwealth.
    2. 110(a)(2)(B) Ambient Air Quality Monitoring/Data System: Section 
110(a)(2)(B) requires SIPs to provide for establishment and operation 
of appropriate devices, methods, systems, and procedures necessary to: 
(i) Monitor, compile, and analyze data on ambient air quality, and (ii) 
upon request, make such data available to the Administrator. These 
requirements are met through KRS 224.10-100 (22), which provides the 
authority to require the installation, maintenance, and use of 
equipment, devices, or tests and methodologies to monitor the nature 
and amount of any substance emitted into the ambient air and to provide 
the information to the Cabinet.
    KDAQ also cites to the following regulations to demonstrate that 
the Commonwealth meets the requirements of this element: 401 KAR 
50:050. Monitoring; 401 KAR 51:017. Prevention of significant 
deterioration of air quality; and 401 KAR 51:052. Review of new sources 
in or impacting upon nonattainment areas; 401 KAR 53:005. General 
provisions; 401 KAR 53:010. Ambient air quality standards.
    Annually, states develop and submit to EPA for approval statewide 
ambient monitoring network plans consistent with the requirements of 40 
CFR parts 50, 53, and 58. The annual network plan involves an 
evaluation of any proposed changes to the monitoring network, includes 
the annual ambient monitoring network design plan and a certified 
evaluation of the agency's ambient monitors and auxiliary support 
equipment.\9\ KDAQ's monitoring network plan was submitted on June 28, 
2019, and approved by EPA on October 3, 2019. Kentucky's approved 
monitoring network plan can be accessed at www.regulations.gov using 
Docket ID No. EPA-R04-OAR-2019-0217. These SIP-approved rules and 
Kentucky's statute, along with Kentucky's Ambient Air Monitoring 
Network Plan, provide for the establishment and operation of ambient 
air quality monitors, the compilation and analysis of ambient air 
quality data, and the submission of these data to EPA upon request. 
Therefore, EPA has made the preliminary determination that Kentucky's 
SIP and practices are adequate for the ambient air quality monitoring 
and data system related to the 2015 8-hour ozone NAAQS.
---------------------------------------------------------------------------

    \9\ On occasion, proposed changes to the monitoring network are 
evaluated outside of the network plan approval process in accordance 
with 40 CFR part 58.
---------------------------------------------------------------------------

    3. 110(a)(2)(C) Programs for Enforcement of Control Measures and 
for Construction or Modification of Stationary Sources: This element 
consists of three sub-elements: Enforcement, state-wide regulation of 
new and modified minor sources and minor modifications of major 
sources, and preconstruction permitting of major sources and major 
modifications in areas designated attainment or unclassifiable for the 
subject NAAQS as required by CAA title I part C (i.e., the major source 
PSD program). EPA's analysis of how these provisions of Kentucky's SIP 
address each sub-element are described below.
    Enforcement: KDAQ's SIP-approved regulation, 401 KAR 50:060, 
Enforcement, provides for enforcement of emission limits and control 
measures associated with ozone through permit terms and conditions, and 
compliance schedules. This regulation also authorizes the Cabinet to 
modify and revoke permits and compliance schedules, and authorizes 
administrative penalties and injunctive relief, citing to statutory 
civil penalty and injunctive relief provisions of KRS 224.99-010. EPA 
has made the preliminary determination that Kentucky's SIP is adequate 
for enforcement related to the 2015 8-hour ozone NAAQS.
    Preconstruction PSD Permitting for Major Sources: With regard to 
section 110(a)(2)(C) related to the programs for preconstruction PSD 
permitting for major sources, EPA is not proposing any action in this 
rulemaking. EPA will consider these requirements in relation to 
Kentucky's 2015 8-hour ozone NAAQS infrastructure submission in a 
separate rulemaking.
    Regulation of minor sources and modifications: Kentucky's SIP-
approved rules, 401 KAR 51:005, Purpose and general provisions and 401 
KAR 52:030, Federally-enforceable permits for non-major sources 
collectively govern the preconstruction permitting of modifications and 
construction of minor stationary sources, and minor modifications of 
major stationary sources.
    EPA has made the preliminary determination that Kentucky's SIP is 
adequate for program enforcement of control measures, and regulation of 
minor sources and modifications related to the 2015 8-hour ozone NAAQS.
    4. 110(a)(2)(D)(i)(I) and (II) Interstate Pollution Transport: 
Section 110(a)(2)(D)(i) has two components: 110(a)(2)(D)(i)(I) and 
110(a)(2)(D)(i)(II). Each of these components has two subparts 
resulting in four distinct components, commonly referred to as

[[Page 14446]]

``prongs,'' that must be addressed in infrastructure SIP submissions. 
The first two prongs, which are codified in section 110(a)(2)(D)(i)(I), 
are provisions that prohibit any source or other type of emissions 
activity in one state from contributing significantly to nonattainment 
of the NAAQS in another state (``prong 1'') and interfering with 
maintenance of the NAAQS in another state (``prong 2''). The third and 
fourth prongs, which are codified in section 110(a)(2)(D)(i)(II), are 
provisions that prohibit emissions activity in one state from 
interfering with measures required to prevent significant deterioration 
of air quality in another state (``prong 3''), or to protect visibility 
in another state (``prong 4'').
    110(a)(2)(D)(i)(I)--prongs 1 and 2: EPA is not proposing any action 
in this rulemaking related to the interstate transport provisions 
pertaining to the contribution to nonattainment or interference with 
maintenance in other states of section 110(a)(2)(D)(i)(I) (prongs 1 and 
2). EPA will consider these requirements in relation to Kentucky's 2015 
8-hour ozone NAAQS infrastructure submission in a separate rulemaking.
    110(a)(2)(D)(i)(II)--prong 3: With regard to section 
110(a)(2)(D)(i)(II), the PSD element, referred to as prong 3, EPA is 
not proposing any action in this rulemaking. EPA will consider these 
requirements in relation to Kentucky's 2015 8-hour ozone NAAQS 
infrastructure submission in a separate rulemaking.
    110(a)(2)(D)(i)(II)--prong 4: Section 110(a)(2)(D)(i)(II) requires 
that the SIP contain adequate provisions to protect visibility in other 
States. This requirement is satisfied for any relevant NAAQS when the 
state has a fully-approved regional haze SIP. Kentucky's SIP contains a 
fully approved Regional Haze Plan (see 84 FR 13800 (April 8, 2019)). 
EPA's approval of the Kentucky regional haze SIP therefore ensures that 
emissions from Kentucky are not interfering with measures to protect 
visibility in other states, satisfying the requirements of prong 4 of 
section 110(a)(2)(D)(i)(II) for the 2015 8-hour ozone NAAQS. EPA has 
made the preliminary determination Kentucky's SIPs meet the 
requirements of prong 4 of section 110(a)(2)(D)(i)(II) for the 2015 8-
hour ozone NAAQS.
    5. 110(a)(2)(D)(ii) Interstate Pollution Abatement and 
International Air Pollution: Section 110(a)(2)(D)(ii) requires SIPs to 
include provisions ensuring compliance with sections 115 and 126 of the 
Act, relating to interstate and international pollution abatement. 
Regulation 401 KAR 51:010. Attainment Status Designations designates 
the status of all areas of the Commonwealth of Kentucky with regard to 
attainment of the NAAQS. Regulation 401 KAR 51:017. Prevention of 
significant deterioration of air quality and Regulation 401 KAR 51:052. 
Review of new sources in or impacting upon nonattainment areas, Section 
1, require Kentucky to provide notice to nearby states that may be 
affected by proposed major source modifications. These regulations cite 
to Federal notification requirements under 40 CFR Sections 51.166 and 
to 401 KAR 52:100. Public, affected state, and the US. EPA review, 
Section 6, which requires that public notice for permit actions be 
provided to affected states. Additionally, Kentucky does not have any 
pending obligation under sections 115 and 126 of the CAA with respect 
to the 2015 ozone NAAQS. EPA has made the preliminary determination 
that Kentucky's SIP is adequate for ensuring compliance with the 
applicable requirements relating to interstate and international 
pollution abatement for the 2015 8-hour ozone NAAQS.
    6. 110(a)(2)(E) Adequate Resources and Authority, Conflict of 
Interest, and Oversight of Local Governments and Regional Agencies: 
Section 110(a)(2)(E) requires that each implementation plan provide: 
(i) Necessary assurances that the state will have adequate personnel, 
funding, and authority under state law to carry out its implementation 
plan, (ii) that the state comply with the requirements respecting state 
boards pursuant to section 128 of the Act, and (iii) necessary 
assurances that, where the state has relied on a local or regional 
government, agency, or instrumentality for the implementation of any 
plan provision, the state has responsibility for ensuring adequate 
implementation of such plan provisions. EPA is proposing to approve 
Kentucky's SIP submission as meeting the requirements of sub-elements 
110(a)(2)(E)(i), (ii), and (iii).
    In support of elements 110(a)(2)(E)(i) and (iii), Kentucky's 
infrastructure submission demonstrates that it is responsible for 
promulgating rules and regulations for the NAAQS, emissions standards, 
general policies, a system of permits, fee schedules for the review of 
plans, and other planning needs. With respect to having the necessary 
funding and authority to implement the Kentucky SIP, Kentucky's State 
statute 401 KAR 50:038. Air Emissions Fee, and the following State 
statutes support sub-elements (i) and (iii): KRS 224.10-100. Powers and 
Duties of the Cabinet and KRS 224.10-020. Departments within the 
cabinet--Offices and divisions within the departments--Appointments. As 
evidence of the adequacy of KDAQ's resources with respect to sub-
elements (i) and (iii), KDAQ has a performance partnership agreement 
with EPA outlining 105 grant commitments and current status of these 
commitments for fiscal year 2018. Annually, the Commonwealth updates 
this performance partnership agreement based on current SIP 
requirements, air quality planning, and applicable requirements related 
to the NAAQS. There were no outstanding issues in relation to the SIP 
for fiscal year 2018, therefore, KDAQ's grants were finalized and 
closed out. With respect to (iii) necessary assurances that, where the 
state has relied on a local or regional government, agency, or 
instrumentality for the implementation of any plan provision, the state 
has responsibility for ensuring adequate implementation of such plan 
provisions, Kentucky's State statute KRS 224.2-130, Concurrent 
jurisdiction with local district provides the Cabinet with oversight 
authority of local programs and concurrent jurisdiction. EPA has made 
the preliminary determination that Kentucky has adequate resources for 
implementation of the 2015 8-hour ozone NAAQS. Accordingly, EPA is 
proposing to approve Kentucky's infrastructure SIP submission with 
respect to section 110(a)(2)(E)(i) and (iii).
    Section 110(a)(2)(E)(ii) requires that Kentucky comply with section 
128 of the CAA. Section 128 requires that (a)(1) the majority of 
members of the state board or body which approves permits or 
enforcement orders represent the public interest and do not derive any 
significant portion of their income from persons subject to permitting 
or enforcement orders under the CAA; (a)(2) any potential conflicts of 
interest by such board or body, or the head of an executive agency with 
similar, powers be adequately disclosed. For purposes of section 
128(a)(1), Kentucky has no boards or bodies with authority over air 
pollution permits or enforcement actions. Such matters are instead 
handled by the Director of the KDAQ. As such, a ``board or body'' is 
not responsible for approving permits or enforcement orders in 
Kentucky, and the requirements of section 128(a)(1) are not applicable. 
For purposes of section 128(a)(2), Kentucky's SIP has been updated. On 
October 3, 2012 (77 FR 60307), EPA took final action to approve KRS 
Chapters 11A.020, 11A.030, 11A.040 and Chapters 224.10-020 and 224.10-
100 into the SIP to address the conflict of interest requirements of

[[Page 14447]]

section 128. These SIP-approved state statutes establish the powers and 
duties of the Cabinet, departments within the Cabinet, and offices and 
divisions within such departments (Chapters 224.10-020 and 224.10-100) 
and support sub-element (ii) by requiring adequate disclosures of 
potential conflicts (KRS 11A.020. Public servant prohibited from 
certain conduct--Exception--Disclosure of personal or private interest) 
and otherwise ensuring that public officers and servants do not engage 
in activities that may present a conflict of interest (KRS 11A.030 
Considerations in determination to abstain from action on official 
decision--Advisory opinion; and KRS 11A.040 Acts prohibited for public 
servant or officer--Exception). With the incorporation of these 
statutes into the Kentucky SIP, the Commonwealth has adequately 
addressed the requirements of section 128(a)(2). Thus, EPA is proposing 
approval of KDAQ's infrastructure SIP submission for the 2015 8-hour 
ozone NAAQS with respect to section 110(a)(2)(E)(ii).
    7. 110(a)(2)(F) Stationary Source Monitoring and Reporting: Section 
110(a)(2)(F) requires SIPs to meet applicable requirements addressing: 
(i) The installation, maintenance, and replacement of equipment, and 
the implementation of other necessary steps, by owners or operators of 
stationary sources to monitor emissions from such sources, (ii) 
periodic reports on the nature and amounts of emissions and emissions 
related data from such sources, and (iii) correlation of such reports 
by the state agency with any emission limitations or standards 
established pursuant to this section, which reports shall be available 
at reasonable times for public inspection. EPA's rules regarding how 
SIPs need to address source monitoring requirements at 40 CFR 51.212 
require SIPs to exclude any provision that would prevent the use of 
credible evidence of noncompliance.
    The Kentucky infrastructure submission demonstrates how the major 
source and minor source emission inventory programs collect emission 
data throughout the Commonwealth and ensure the quality of such data. 
Kentucky meets these requirements through Chapter 50 General 
Administrative Procedures, specifically 401 KAR 50:050 Monitoring. 401 
KAR 50:050, Section 1, Monitoring Records and Reporting, states that 
the Cabinet may require a facility to install, use, and maintain stack 
gas and ambient air monitoring equipment and to establish and maintain 
records, and make periodic emission reports at intervals prescribed by 
the Cabinet. Also, KRS 224.10-100 (23) requires that any person engaged 
in any operation regulated pursuant to this chapter file with the 
Cabinet reports containing information as to location, size, height, 
rate of emission or discharge, and composition of any substance 
discharged or emitted into the ambient air or into the waters or onto 
the land of the Commonwealth, and such other information the Cabinet 
may require. In addition, EPA is unaware of any provision preventing 
the use of credible evidence in the Kentucky SIP.
    Additionally, Kentucky is required to submit emissions data to EPA 
for purposes of the National Emissions Inventory (NEI), pursuant to 
Subpart A to 40 CFR part 51,--``Air Emissions Reporting Requirements,'' 
(AERR). All states are required to submit a comprehensive emission 
inventory every three years and report emissions for certain larger 
sources annually through EPA's online Emissions Inventory System. 
States report emissions data for the six criteria pollutants and the 
precursors that form them--nitrogen oxides, sulfur dioxides, ammonia, 
lead, carbon monoxide, particulate matter, and volatile organic 
compounds. Many states also voluntarily report emissions of hazardous 
air pollutants. Kentucky's most recently published triennial compiled 
emissions information is available as part of the 2014 NEI. EPA 
compiles the emissions data, supplementing it where necessary, and 
releases it to the general public through the website https://www.epa.gov/air-emissions-inventories.\10\
---------------------------------------------------------------------------

    \10\ EPA compiles the emissions data and releases the National 
Emissions Inventory (NEI) to the public triennial. According to 
EPA's 2017 NEI Plan, the 2017 NEI will be available on April 1, 
2020, See https://www.epa.gov/sites/production/files/2019-04/documents/2017nei_plan_addendum_final_apr2019_0.pdf
---------------------------------------------------------------------------

    EPA has made the preliminary determination that Kentucky's SIP and 
practices are adequate for the stationary source monitoring systems 
related to the 2015 8-hour ozone NAAQS. Accordingly, EPA is proposing 
to approve Kentucky's infrastructure SIP submission with respect to 
section 110(a)(2)(F).
    8. 110(a)(2)(G) Emergency Powers: This section requires that states 
demonstrate authority comparable with section 303 of the CAA and 
adequate contingency plans to implement such authority. Section 303 
authorizes EPA to take action seeking to immediately restrain pollution 
sources if such pollution is presenting an imminent and substantial 
endangerment to public health, welfare, or the environment. Kentucky's 
infrastructure SIP submission identifies air pollution emergency 
episodes and preplanned abatement strategies as outlined in the 
following Kentucky regulations in Chapter 55 Emergency Episodes, 
specifically: 401 KAR 55:005. Significant harm criteria, 401 KAR 
55:010. Episode Criteria, and 401 KAR 55:015. Episode Declaration.401 
KAR 55:020, Abatement, 401 KAR 55:005. Significant Harm Criteria, 
Section 1, Purpose, defines those levels of pollutant concentration 
which must be prevented in order to avoid significant harm to the 
health of persons. 401 KAR 55:010. Episodic Criteria defines those 
levels of pollutant concentrations which justify the proclamation of an 
air pollution alert, air pollution warning, an air pollution emergency. 
401 KAR 55:015. Episode Declaration provides for the curtailment or 
reduction of processes or operations which emit an air contaminant or 
an air contaminant precursor whose criteria has been reached and are 
located in the affected areas for which an episode level has been 
declared.
    In addition, KRS 224.10-100 Powers and duties of cabinet and KRS 
224.10-410 Order for discontinuance, abatement, or alleviation of 
condition or activity without hearing--Subsequent hearing, establish 
the authority for Kentucky's secretary to issue orders to person(s) for 
discontinuance, abatement, or alleviation of any condition or activity 
without hearing because the condition or activity presents a danger to 
the health or welfare of the people of the state, and for the Cabinet 
to require adoption of any remedial measures deemed necessary. EPA has 
made the preliminary determination that Kentucky's SIP, and state laws 
are adequate for emergency powers related to the 2015 8-hour ozone 
NAAQS. Accordingly, EPA is proposing to approve Kentucky's 
infrastructure SIP submission with respect to section 110(a)(2)(G).
    9. 110(a)(2)(H) SIP Revisions: Section 110(a)(2)(H), in summary, 
requires each SIP to provide for revisions of such plan: (i) As may be 
necessary to take account of revisions of such national primary or 
secondary ambient air quality standard or the availability of improved 
or more expeditious methods of attaining such standard, and (ii) 
whenever the Administrator finds that the plan is substantially 
inadequate to attain the NAAQS or to otherwise comply with any 
additional applicable requirements. As previously discussed, KDAQ is 
responsible for adopting air quality rules and revising SIPs as

[[Page 14448]]

needed to attain or maintain the NAAQS. Kentucky has the ability and 
authority to respond to calls for SIP revisions and has provided a 
number of SIP revisions over the years for implementation of the NAAQS.
    Additionally, 401 KAR 53:010 outlines the ambient air quality 
standards necessary for the protection of the public health, the 
general welfare, and the property and people in the Commonwealth and 
states that within 60 days of promulgation or revision of any NAAQS by 
EPA, the Cabinet will initiate a process to promulgate or review this 
administrative regulation. 401 KAR 51:010. Attainment Status 
Designations provides provisions for the Cabinet to review applicable 
data and submit to EPA proposed revisions to the list of attainment-
nonattainment areas. EPA has made the preliminary determination that 
Kentucky adequately demonstrates a commitment to provide future SIP 
revisions related to the 2015 8-hour ozone NAAQS when necessary. 
Accordingly, EPA is proposing to approve Kentucky's infrastructure SIP 
submission for the 2015 8-hour ozone NAAQS with respect to section 
110(a)(2)(H).
    10. 110(a)(2)(J) Consultation with Government Officials, Public 
Notification, and PSD and Visibility Protection: EPA is proposing to 
approve Kentucky's infrastructure SIP submission for the 2015 8-hour 
ozone NAAQS with respect to the general requirement in section 
110(a)(2)(J) to include a program in the SIP that provides for meeting 
the applicable consultation requirements of section 121, and the public 
notification requirements of section 127. EPA's rationale for each sub-
element is described below.
    Consultation with government officials (121 consultation): Section 
110(a)(2)(J) of the CAA requires states to meet the requirements of 
section 121 relating to consultation with local governments, designated 
organizations and Federal Land Managers (FLMs) carrying out NAAQS 
implementation requirements pursuant to section 121 relative to 
consultation. This requirement is met through the Regional Haze SIP, 
which provides for continued consultation with government officials, 
including the FLMs. Kentucky also adopted consultation procedures in 
coordination with the transportation partners in the Commonwealth, for 
the implementation of transportation conformity, which includes the 
development of mobile inventories for SIP development. Implementation 
of transportation conformity as outlined in the consultation procedures 
requires KDAQ to consult with Federal, state and local transportation 
and air quality agency officials on the development of motor vehicle 
emissions budgets. Also, KDAQ notes in its January 1, 2019, SIP 
submission that the following Kentucky regulations provide the 
Commonwealth the authority to meet this requirement: 401 KAR 50:055. 
General compliance requirements; 401 KAR 50:060. Enforcement; 401 KAR 
50:065. Conformity of general federal actions; 401 KAR 50:066. 
Conformity of Transportation Plans, Programs, and Projects; 401 KAR 
51:017. Prevention of Significant Deterioration of Air Quality; and 401 
KAR 51:052. Review of new sources in or impacting upon nonattainment 
areas. EPA has made the preliminary determination that Kentucky's SIP 
and practices adequately demonstrate consultation with government 
officials related to the 2015 8-hour ozone NAAQS when necessary for the 
consultation with government official(s) element of section 
110(a)(2)(J).
    Public notification (127 public notification): With respect to 
public notification, section 110(a)(3)(J) of the CAA requires states to 
notify the public of NAAQS exceedances and associated health hazards, 
and to enhance public awareness of measures that can prevent such 
exceedances. These requirements are met through the following Kentucky 
regulations: 401 KAR 51:001. Definitions for 401 KAR Chapter 51; 401 
KAR 51:005. Purpose and General Provisions; 401 KAR 51:010. Attainment 
Status Designations; 401 KAR 51:017. Prevention of significant 
deterioration of air quality; 401 KAR 51:052. Review of new sources in 
or impacting upon nonattainment areas; and 401 KAR 52:100. Public, 
Affected State, and the US EPA Review. Additionally, Kentucky provides 
air quality information to the public via its website at: http://eppcapp.ky.gov/daq/. EPA has made the preliminary determination that 
Kentucky's SIP and practices adequately demonstrate the Commonwealth's 
ability to provide public notification related to the 2015 8-hour ozone 
NAAQS when necessary for the public notification element of section 
110(a)(2)(J).
    PSD: With regard to the PSD element of section 110(a)(2)(J), EPA is 
not proposing any action in this rulemaking. EPA will consider these 
requirements in relation to Kentucky's 2015 8-hour ozone NAAQS 
infrastructure submission in a separate rulemaking.
    Visibility protection: EPA's 2013 Guidance notes that it does not 
treat the visibility protection aspects of section 110(a)(2)(J) as 
applicable for purposes of the infrastructure SIP approval process. 
KDAQ referenced its regional haze program as germane to the visibility 
component of section 110(a)(2)(J). EPA recognizes that states are 
subject to visibility protection and regional haze program requirements 
under Part C of the Act (which includes sections 169A and 169B). 
However, there are no newly applicable visibility protection 
obligations after the promulgation of a new or revised NAAQS. Thus, EPA 
has determined that states do not need to address the visibility 
component of 110(a)(2)(J) in infrastructure SIP submittals. As such, 
EPA has made the preliminary determination that Kentucky's 
infrastructure SIP submission is approvable for section 110(a)(2)(J) 
related to the 2015 8-hour ozone NAAQS and that Kentucky does not need 
to rely on its regional haze program to address this element.
    11. 110(a)(2)(K) Air Quality Modeling and Submission of Modeling 
Data: Section 110(a)(2)(K) of the CAA requires that SIPs provide for 
performing air quality modeling so that effects on air quality of 
emissions from NAAQS pollutants can be predicted and submission of such 
data to EPA can be made. With regard to section 110(a)(2)(K), air 
quality models, EPA is not proposing any action in this rulemaking. EPA 
will consider these requirements in relation to Kentucky's 2015 8-hour 
ozone NAAQS infrastructure submission in a separate rulemaking.
    12. 110(a)(2)(L) Permitting Fees: This section requires the SIP to 
direct the owner or operator of each major stationary source to pay to 
the permitting authority, as a condition of any permit required under 
the CAA, a fee sufficient to cover: (i) The reasonable costs of 
reviewing and acting upon any application for such a permit, and (ii) 
if the owner or operator receives a permit for such source, the 
reasonable costs of implementing and enforcing the terms and conditions 
of any such permit (not including any court costs or other costs 
associated with any enforcement action), until such fee requirement is 
superseded with respect to such sources by the Administrator's approval 
of a fee program under title V.
    Kentucky regulation, 401 KAR 50:038 Air Emissions Fee,\11\ provides 
for the assessment of fees necessary to fund the state permit program. 
KDAQ ensures this is sufficient for the reasonable cost of reviewing 
and acting upon PSD and NNSR permits. Additionally, Kentucky has a 
fully approved title V operating permit program at 401 KAR 52:020 Title

[[Page 14449]]

V permits \12\ that covers the cost of implementation and enforcement 
of PSD and NNSR permits after they have been issued. EPA has made the 
preliminary determination that Kentucky's SIP and practices adequately 
provide for permitting fees related to the 2015 8-hour ozone NAAQS, 
when necessary. Accordingly, EPA is proposing to approve Kentucky's 
infrastructure SIP submission with respect to section 110(a)(2)(L).
---------------------------------------------------------------------------

    \11\ This rule is not approved into the federally approved SIP.
    \12\ This rule is not approved into the federally approved SIP.
---------------------------------------------------------------------------

    13. 110(a)(2)(M) Consultation and Participation by Affected Local 
Entities: Section 110(a)(2)(M) of the Act requires states to provide 
for consultation and participation in SIP development by local 
political subdivisions affected by the SIP. Kentucky regulation, 401 
KAR 50:066. Conformity of transportation plans, programs, and projects, 
and the interagency consultation process as directed by Kentucky's 
approved Conformity SIP and 40 CFR 93.112 provide for consultation with 
local groups. More specifically, Kentucky adopted state-wide 
consultation procedures for the implementation of transportation 
conformity which includes the development of mobile inventories for SIP 
development and the requirements that link transportation planning and 
air quality planning in nonattainment and maintenance areas. Required 
partners covered by Kentucky's consultation procedures include Federal, 
state and local transportation and air quality agency officials. 
Further, Kentucky's ozone infrastructure SIP submission notes that the 
following State regulations and State statutes provide the Commonwealth 
the authority to meet the requirements of this element; 401 KAR 52:100. 
Public, Affected State, and the U.S. EPA Review; and KRS Chapter 77. 
Air Pollution Control. EPA has made the preliminary determination that 
Kentucky's SIP and practices adequately demonstrate consultation with 
affected local entities related to the 2015 8-hour ozone NAAQS when 
necessary.

V. Proposed Action

    With the exception of interstate transport provisions of section 
110(a)(2)(D)(i)(I) and (II) (prongs 1 and 2), PSD provisions related to 
major sources under section 110(a)(2)(C), 110(a)(2)(D)(i)(II) (prong 3) 
and 110(a)(2)(J), and air quality models of section 110(a)(2)(K), EPA 
is proposing to approve Kentucky's January 9, 2019, infrastructure SIP 
submission for the 2015 8-hour ozone NAAQS for the above described 
infrastructure SIP requirements. EPA is proposing to approve these 
portions of Kentucky's infrastructure SIP submission for the 2015 8-
hour ozone NAAQS because these aspects of the submission are consistent 
with section 110 of the CAA.

VI. Statutory and Executive Order Reviews

    Under the CAA, the Administrator is required to approve a SIP 
submission that complies with the provisions of the Act and applicable 
federal regulations. See 42 U.S.C. 7410(k); 40 CFR 52.02(a). Thus, in 
reviewing SIP submissions, EPA's role is to approve state choices, 
provided that they meet the criteria of the CAA. Accordingly, this 
proposed action merely proposes to approve state law as meeting federal 
requirements and would not impose additional requirements beyond those 
imposed by state law. For that reason, this proposed action:
     Is not a significant regulatory action subject to review 
by the Office of Management and Budget under Executive Orders 12866 (58 
FR 51735, October 4, 1993) and 13563 (76 FR 3821, January 21, 2011);
     does not impose an information collection burden under the 
provisions of the Paperwork Reduction Act (44 U.S.C. 3501 et seq.);
     is certified as not having a significant economic impact 
on a substantial number of small entities under the Regulatory 
Flexibility Act (5 U.S.C. 601 et seq.);
     does not contain any unfunded mandate or significantly or 
uniquely affect small governments, as described in the Unfunded 
Mandates Reform Act of 1995 (Pub. L. 104-4);
     does not have Federalism implications as specified in 
Executive Order 13132 (64 FR 43255, August 10, 1999);
     is not an economically significant regulatory action based 
on health or safety risks subject to Executive Order 13045 (62 FR 
19885, April 23, 1997);
     is not a significant regulatory action subject to 
Executive Order 13211 (66 FR 28355, May 22, 2001);
     is not subject to requirements of Section 12(d) of the 
National Technology Transfer and Advancement Act of 1995 (15 U.S.C. 272 
note) because application of those requirements would be inconsistent 
with the CAA; and
     does not provide EPA with the discretionary authority to 
address, as appropriate, disproportionate human health or environmental 
effects, using practicable and legally permissible methods, under 
Executive Order 12898 (59 FR 7629, February 16, 1994).
    In addition, the 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. In those areas of Indian 
country, the rule does not have tribal implications as specified by 
Executive Order 13175 (65 FR 67249, November 9, 2000), nor will it 
impose substantial direct costs on tribal governments or preempt tribal 
law.
