Additional Air Quality Designations for the 2015 Ozone National 
Ambient Air Quality Standards

AGENCY: Environmental Protection Agency (EPA).

ACTION: Final rule.

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

SUMMARY: This rule establishes initial air quality designations for 
certain areas in the United States, including areas of Indian country, 
for the 2015 primary and secondary national ambient air quality 
standards (NAAQS) for ozone. On November 6, 2017, the Environmental 
Protection Agency (EPA) designated about 85 percent of the country as 
attainment/unclassifiable and three counties as unclassifiable. In this 
action, the EPA is designating all remaining areas, except for eight 
counties in the San Antonio, Texas metropolitan area. Areas are being 
designated as either nonattainment, attainment/unclassifiable, or 
unclassifiable. Areas designated as nonattainment are also being 
classified by operation of law according to the severity of their air 
quality problems. The classification categories are Marginal, Moderate, 
Serious, Severe, and Extreme. In addition, five nonattainment areas in 
California are being voluntarily reclassified to a higher 
classification.

DATE:  The effective date of this rule is August 3, 2018.

II. What is the purpose of this action?

    The purpose of this action is to announce and promulgate initial 
area designations for certain areas of the country with respect to the 
2015 primary and secondary NAAQS for ozone, in accordance with the 
requirements of Clean Air Act (CAA) section 107(d). The EPA is 
designating areas as either nonattainment, attainment/unclassifiable, 
or unclassifiable. In addition, this action announces the 
classification for nonattainment areas, which occurs by operation of 
law at the time of designation and is based on the severity of each 
area's ozone air quality problems. This action also reclassifies five 
areas in California to a higher classification. The classification 
categories are Marginal, Moderate, Serious, Severe, and Extreme. The 
EPA established the air quality thresholds that define the 
classifications in a separate rule titled, ``Implementation of the 2015 
National Ambient Air Quality Standards for Ozone: Nonattainment Area 
Classifications Approach'' (Classifications Rule) (83 FR 10376; March 
9, 2018).
    The list of all areas being designated in this action appear in the 
regulatory tables included at the end of this final rule. These tables, 
which will amend 40 CFR part 81, identify the designation and the 
classification for each nonattainment area.
    In this action, the EPA is designating 51 areas as nonattainment. 
Consistent with the EPA's ``Policy for Establishing Separate Air 
Quality Designations for Areas of Indian Country'' (December 20, 2011), 
the EPA is designating certain lands of the Pechanga Tribe and the 
Morongo Tribe in Southern California as separate nonattainment 
areas.\1\ Seven of the nonattainment areas are multi-state areas. The 
EPA is also designating one area as unclassifiable. The EPA is 
designating all the other areas addressed in this final action, 
including both state and tribal areas, as attainment/unclassifiable. 
With this action, the EPA has issued final designations for all areas 
of the country with the exception of eight counties in the San Antonio, 
Texas, metropolitan area. The EPA intends to issue final designations 
for these eight counties by July 17, 2018.
---------------------------------------------------------------------------

    \1\ Designation guidance for the 2015 ozone NAAQS is available 
at https://www.epa.gov/ozone-designations/epa-guidance-area-designations-2015-ozone-naaqs.
---------------------------------------------------------------------------

    The EPA is basing the designations on the most recent 3 years of 
certified ozone air quality monitoring data and on an evaluation of 
factors to assess contributions to nonattainment in nearby areas. State 
areas designated as nonattainment are subject to planning and emission 
reduction requirements as specified in CAA part D. Requirements vary 
according to an area's classification. On November 17, 2016, the EPA 
proposed an implementation rule to assist states in the development of 
state implementation plans for attaining the ozone standards (81 FR 
81276). The EPA expects to finalize this rule as soon as possible after 
finalizing the nonattainment area designations for the 2015 ozone 
NAAQS.

III. What is ozone and how is it formed?

    Ground-level ozone is a gas that is formed by the reaction of 
volatile organic compounds (VOCs) and oxides of nitrogen 
(NOX) in the atmosphere in the presence of sunlight. These 
precursor emissions are emitted by many types of pollution sources, 
including power plants and industrial emissions sources, on-road and 
off-road motor vehicles and engines, and smaller sources, collectively 
referred to as area sources. Ozone is predominately a summertime air 
pollutant. However, high ozone concentrations have also been observed 
in cold months, where a few areas in the Western United States (U.S.) 
have experienced high levels of local VOC and NOX emissions 
that have formed ozone when snow is on the ground and temperatures are 
near or below freezing. Ozone and ozone precursors can be transported 
to an area from sources in nearby areas or from sources located 
hundreds of miles away. For purposes of determining ozone nonattainment 
area boundaries, the CAA requires the EPA to include areas that 
contribute to nearby violations of the NAAQS.

IV. What are the 2015 ozone NAAQS and the health and welfare concerns 
they address?

    On October 1, 2015, the EPA revised both the primary and secondary 
NAAQS for ozone to a level of 0.070 parts per

[[Page 25778]]

million (ppm) (annual fourth-highest daily maximum 8-hour average 
concentration, averaged over 3 years).\2\ The level of the ozone NAAQS 
previously set in 2008 is 0.75 ppm. The 2015 ozone NAAQS retain the 
same general form and averaging time as the 2008 ozone NAAQS.
---------------------------------------------------------------------------

    \2\ See 80 FR 65296; October 26, 2015, for a detailed 
explanation of the calculation of the 3-year 8-hour average and 40 
CFR part 50, Appendix U.
---------------------------------------------------------------------------

    The primary ozone standards provide protection for children, older 
adults, and people with asthma or other lung diseases, and other at-
risk populations against an array of adverse health effects that 
include reduced lung function, increased respiratory symptoms and 
pulmonary inflammation; effects that contribute to emergency department 
visits or hospital admissions; and mortality. The secondary ozone 
standards protect against adverse effects to the public welfare, 
including those related to impacts on sensitive vegetation and forested 
ecosystems.

V. What are the CAA requirements for air quality designations?

    When the EPA promulgates a new or revised NAAQS, the EPA is 
required to designate all areas in the country as nonattainment, 
attainment, or unclassifiable, pursuant to section 107(d)(1) of the 
CAA. Section 107(d)(1)(A)(i) of the CAA defines a nonattainment area 
as, ``any area that does not meet (or that contributes to ambient air 
quality in a nearby area that does not meet) the national primary or 
secondary ambient air quality standard for the pollutant.'' If an area 
meets either prong of this definition, states should recommend and the 
EPA is obligated to designate the area as ``nonattainment.'' CAA 
section 107(d)(1)(A)(ii) defines an attainment area as any area that 
does not meet the definition of nonattainment and that meets the NAAQS. 
CAA section 107(d)(1)(A)(iii) provides that any area that the EPA 
cannot designate on the basis of available information as meeting or 
not meeting the standards should be designated as ``unclassifiable.'' 
Historically for ozone, the EPA has designated most areas that do not 
meet the definition of nonattainment as ``unclassifiable/attainment.'' 
This category includes areas that have air quality monitoring data 
meeting the NAAQS and areas that do not have monitors but for which the 
EPA has no evidence that the areas may be violating the NAAQS or 
contributing to a nearby violation. In the designations for the 2015 
ozone NAAQS, the EPA has reversed the order of the label to be 
attainment/unclassifiable to better convey the definition of the 
designation category and so that the category is more easily 
distinguished from the separate unclassifiable category. In a few 
instances, based on circumstances where some monitoring data are 
available but are not sufficient for a determination that an area is or 
is not attaining the NAAQS, the EPA has designated an area as 
``unclassifiable.''
    Section 107(d)(1)(B) of the CAA requires the EPA to issue initial 
area designations within 2 years of promulgating a new or revised 
NAAQS. However, if the Administrator has insufficient information to 
make these designations within that time frame, the EPA has the 
authority to extend the deadline for designation decisions by up to 1 
additional year.
    By not later than 1 year after the promulgation of a new or revised 
NAAQS, each state governor is required to recommend air quality 
designations, including the appropriate boundaries for areas, to the 
EPA. (See CAA section 107(d)(1)(A).) The EPA reviews those state 
recommendations and is authorized to make any modifications the 
Administrator deems necessary. The statute does not define the term 
``necessary,'' but the EPA interprets this to authorize the 
Administrator to modify designation recommendations that are 
inconsistent with the statutory language, including modification of 
recommended boundaries for nonattainment areas that are not supported 
by the facts or analysis. If the EPA intends to modify a state's 
recommendation, section 107(d)(1)(B) of the CAA requires the EPA to 
notify the state of any such intended modifications not less than 120 
days prior to the EPA's promulgation of the final designation. These 
notifications are commonly known as the ``120-day letters.'' If the 
state does not agree with the EPA's intended modification, the 120-day 
period provides an opportunity for the state to demonstrate to the EPA 
why it believes any modification proposed by the EPA is inappropriate. 
If a state fails to provide any recommendation for an area, in whole or 
in part, the EPA must promulgate a designation that the Administrator 
deems appropriate.
    The terms ``contributes to'' and ``nearby'' in the definition of a 
nonattainment area are not defined in the statute and the EPA has 
discretion to interpret these ambiguous terms, based on considerations 
such as the nature of a specific pollutant, the types of sources that 
may contribute to violations, the form of the relevant NAAQS, and any 
other relevant information. The EPA does not interpret the statute to 
require the agency to establish bright line tests or thresholds for 
what constitutes ``contribution'' or ``nearby'' for purposes of 
designations.\3\
---------------------------------------------------------------------------

    \3\ This view was confirmed in Catawba County v. EPA, 571 F.3d 
20 (D.C. Cir. 2009).
---------------------------------------------------------------------------

    Section 301(d) of the CAA authorizes the EPA to approve eligible 
Indian tribes to implement provisions of the CAA on Indian reservations 
and other areas within the tribes' jurisdiction. The Tribal Authority 
Rule (TAR) (40 CFR part 49), which implements section 301(d) of the 
CAA, sets forth the criteria and process for tribes to apply to the EPA 
for eligibility to administer CAA programs. The designations process 
contained in section 107(d) of the CAA is included among those 
provisions determined to be appropriate by the EPA for treatment of 
tribes in the same manner as states. Under the TAR, tribes generally 
are not subject to the same submission schedules imposed by the CAA on 
states. As authorized by the TAR, tribes may seek eligibility to submit 
designation recommendations to the EPA.

VI. What is the chronology for this designations rule and what guidance 
did the EPA provide?

    On February 25, 2016, the EPA issued guidance for states and tribal 
agencies to use for purposes of making designation recommendations as 
required by CAA section 107(d)(1)(A). (See February 25, 2016, 
memorandum from Janet G. McCabe, Acting Assistant Administrator, to 
Regional Administrators, Regions 1-10, titled, ``Area Designations for 
the 2015 Ozone National Ambient Air Quality Standards'' (Designations 
Guidance)). The Designations Guidance provided the anticipated timeline 
for designations and identified important factors that the EPA 
recommended states and tribes consider in making their recommendations 
and that EPA intended to consider in promulgating designations. These 
factors include air quality data, emissions and emissions-related data, 
meteorological data, geography/topography, and jurisdictional 
boundaries. In the Designations Guidance, the EPA asked that states and 
tribes submit their designation recommendations, including appropriate 
area boundaries, to the EPA by October 1, 2016. The EPA had previously 
issued two guidance memoranda related to designating areas of Indian 
country that also apply for designations for the 2015 ozone NAAQS. (See 
December 20, 2011, memorandum from Stephen D. Page,

[[Page 25779]]

Director, Office of Air Quality Planning and Standards, to Regional Air 
Directors, Regions I-X, titled, ``Policy for Establishing Separate Air 
Quality Designations for Areas of Indian Country,'' and December 20, 
2011, memorandum from Stephen D. Page, Director, Office of Air Quality 
Planning and Standards, to Regional Air Directors, Regions I-X, titled, 
``Guidance to Regions for Working with Tribes during the National 
Ambient Air Quality Standards (NAAQS) Designations Process.'') In the 
Designation Guidance, the EPA indicated the agency expected to complete 
the initial designations for the 2015 ozone NAAQS on a 2-year schedule, 
by October 1, 2017, consistent with CAA 107(d)(1)(B)(i).
    On November 6, 2017, the EPA designated as attainment/
unclassifiable 2,646 counties,\4\ including tribal lands within those 
counties, for which the states recommended a designation of attainment 
or attainment/unclassifiable. This represents about 85 percent of the 
counties in the U.S. The EPA also designated a three-county area in 
Washington as unclassifiable as recommended by the state. Consistent 
with the EPA's Tribal Designation Guidance, the EPA designated two 
areas of Indian country (Fond du Lac Band of Lake Superior Chippewa 
Indians and Forest County Potawatomi Community) as separate attainment/
unclassifiable areas.
---------------------------------------------------------------------------

    \4\ Any reference to ``counties'' in this action also includes 
non-county administrative or statistical areas that are comparable 
to counties. Louisiana parishes; the organized boroughs of Alaska; 
the District of Columbia; and the independent cities of the states 
of Virginia, Maryland, Missouri, and Nevada are equivalent to 
counties for administrative purposes. Alaska's Unorganized Borough 
is divided into 10 census areas that are statistically equivalent to 
counties. As of 2017, there are currently 3,142 counties and county-
equivalents in the U.S.
---------------------------------------------------------------------------

    On December 4, 2017, a coalition of environmental and health 
organizations filed suit against the Administrator claiming that EPA 
failed to meet its mandatory obligation to designate all areas of the 
United States for the 2015 ozone NAAQS by October 1, 2017. American 
Lung Association, et al. v. Pruitt (N.D. Cal. No. 4:17-cv-06900). A 
coalition of 15n states also filed a similar suit on December 5, 2017. 
State of California v. Pruitt (N.D. Cal. No. 4:17-cv-06936). The United 
States District Court for the Northern District of California heard 
arguments on plaintiffs' motions for summary judgment in both cases on 
February 22, 2018. In a March 12, 2018, order, the court granted the 
motions in part and ordered the EPA ``to promulgate final designations 
for all areas of the country except for the eight undesignated counties 
composing the San Antonio area no later than April 30, 2018'' and ``to 
promulgate final designations for the San Antonio area no later than 
127 days from the date of this order.'' The designation deadline for 
eight-county San Antonio area is July 17, 2018.
    On or about December 22, 2017, the EPA sent 120-day letters to 
Governors and tribal leaders notifying them of the EPA's preliminary 
response to their designation recommendations for all areas of the 
country not designated in the November 2017 action, with the exception 
of eight counties in the San Antonio metropolitan area. For the areas 
addressed in the 120-day letters, the EPA requested that states and 
tribes submit any additional information that they wanted the EPA to 
consider in making final designation decisions by February 28, 2018, 
including any certified 2017 air quality monitoring data.
    Although not required by section 107(d)(2)(B) of the CAA, the EPA 
also provided a 30-day public comment period on the designation 
recommendations from states and tribes and the EPA's intended 
designations addressed in the 120-day letters to states and tribes. The 
EPA announced the public comment period in the Federal Register on 
January 5, 2018 (83 FR 651). In that notice, the EPA indicated that the 
agency intended to complete the designations for the areas addressed in 
the responses to states and tribes by April 30, 2018.
    State and tribal recommendations and the EPA's preliminary 
responses are posted on EPA's website at https://www.epa.gov/ozone-designations and are available in the docket for the designations 
action. Comments from the states, tribes and the public, and EPA's 
responses to significant comments, are also available in the docket in 
the individual technical support documents for specific areas and in a 
Response to Comments document.

VII. What air quality data has the EPA used to designate areas for the 
2015 ozone NAAQS?

    The final ozone designations in this action are based primarily on 
air quality monitoring data from the years 2014-2016, which were the 
most recent data that states were required to certify at the time the 
EPA notified the states of its intended modifications to their 
recommendations. Under 40 CFR 58.16, states are required to report all 
monitored ozone air quality data and associated quality assurance data 
within 90 days after the end of each quarterly reporting period, and 
under 40 CFR part 58.15(a)(2) states are required to submit annual 
summary reports and a data certification letter to the EPA by May 1 for 
ozone air quality data collected in the previous calendar year. Thus, 
at the time of the 120-day letters, the most recent certification 
obligation was for air quality data from 2016. In the 120-day 
notification letters to states, the EPA indicated that in order for the 
EPA to consider air quality data for the period 2015-2017 in the final 
designation decisions for any area, a state must submit certified, 
quality assured 2015-2017 air quality monitoring data for the area to 
the EPA by February 28, 2018. Several states chose to submit early 
certified air quality data for areas within their states. For those 
areas, the EPA is basing the final designation decisions on air quality 
data from 2015-2017.

VIII. What are the ozone air quality classifications?

    In accordance with CAA section 181(a)(1), each area designated as 
nonattainment for the ozone NAAQS is classified by operation of law at 
the same time as the area is designated by the EPA. Under Subpart 2 of 
part D of title I of the CAA, state planning and emissions control 
requirements for ozone are determined, in part, by a nonattainment 
area's classification. The ozone nonattainment areas are classified 
based on the severity of their ozone levels (as determined based on the 
area's ``design value,'' which represents air quality in the area for 
the most recent 3 years).\5\ The possible classifications are Marginal, 
Moderate, Serious, Severe, and Extreme. Nonattainment areas with a 
``lower'' classification have ozone levels that are closer to the 
standard than areas with a ``higher'' classification. Areas in the 
lower classification levels have fewer and/or less stringent mandatory 
air quality planning and control requirements than those in higher 
classifications. On March 9, 2018 (83 FR 10376), the EPA published the 
Classifications Rule that establishes how the statutory classifications 
will apply for the 2015 ozone NAAQS, including the air quality 
thresholds for each classification category. Each

[[Page 25780]]

nonattainment area's design value, based on the most recent 3 years of 
certified air quality monitoring data, is used to establish the 
classification for the area. See Table 1.
---------------------------------------------------------------------------

    \5\ The air quality design value for the 8-hour ozone NAAQS is 
the 3-year average of the annual 4th highest daily maximum 8-hour 
average ozone concentration. See 40 CFR part 50, Appendix U.

The regulatory tables included at the end of this action provide the 
classification for each designated nonattainment area for the 2015 
ozone NAAQS based on the design value for the area and the 
classification thresholds established in the Classification Rule.

IX. What action is EPA taking to reclassify five California 
nonattainment areas?

    The CAA provides states with a mechanism for addressing 
nonattainment areas that may not be able to attain by the attainment 
date for their classification. Pursuant to CAA section 181(b)(3), a 
state may voluntarily request that the EPA reclassify a nonattainment 
area to a higher classification. The EPA may not deny and must approve 
any such voluntary reclassification requests. Once an area is 
reclassified to a higher classification, it becomes subject to the 
associated additional planning and control requirements for that higher 
classification, and must attain the standard no later than the maximum 
attainment date for that classification. Six nonattainment areas in 
California were granted voluntary reclassifications to a higher 
classification for both the 1997 and 2008 ozone NAAQS. For the 2008 
ozone NAAQS, the EPA proposed to interpret the voluntary 
reclassification requests for the 1997 ozone NAAQS to also apply for 
the more stringent 2008 ozone NAAQS, unless the state expressly 
requested otherwise. As part of the proposal for the Classifications 
Rule for the 2015 NAAQS, the EPA proposed to again apply previous 
voluntary reclassifications for potential nonattainment areas in 
California for the 2015 ozone NAAQS, unless the state of California 
explicitly requested otherwise in their comments on that proposal 
(November 17, 2016; 81 FR 81285).\6\ These areas included Los Angeles-
South Coast Air Basin, San Joaquin Valley, Riverside County (Coachella 
Valley), Sacramento Metro, Ventura County and Los Angeles-San 
Bernardino Counties (Western Mojave) areas. The EPA believes this is an 
appropriate mechanism to address attainment planning for these 
California areas that were voluntarily reclassified for the 1997 ozone 
NAAQS and previously used this mechanism for the 2008 ozone NAAQS. The 
reclassifications will ensure that these areas will have an attainment 
date for the 2015 ozone NAAQS that is no earlier than the areas' 
attainment date for the 2008 ozone NAAQS. The EPA proposed this 
approach in order to minimize the burden on the state of California to 
separately initiate the voluntary reclassification process again. Areas 
for which California declined voluntary reclassification would be 
classified at the time of designation for the 2015 ozone NAAQS based on 
the most recent 3 years of certified air quality monitoring data. In 
response to EPA's proposal, California declined reclassification only 
for the Sacramento Metro area.
---------------------------------------------------------------------------

    \6\ Proposed rule, ``Implementation of the 2015 National Ambient 
Air Quality Standards for Ozone: Nonattainment Area Classifications 
and State Implementation Plan Requirements.''
---------------------------------------------------------------------------

    Consistent with the comments received from the state of California 
on the November 2016 proposal, the EPA is applying previous voluntary 
reclassifications for five of the six California areas originally 
proposed. The following areas are voluntarily reclassified to a higher 
classification for the 2015 ozone NAAQS: Ventura County, CA--Serious; 
Riverside County (Coachella Valley), CA--Severe-15; Los Angeles-San 
Bernardino Counties (West Mojave Desert), CA--Severe-15; Los Angeles-
South Coast Air Basin, CA--Extreme; and San Joaquin Valley, CA--
Extreme. These classifications are reflected in the tables at the end 
of this final rule.

X. How can states request that an area within 5 percent of the upper or 
lower limit of a classification threshold be reclassified?

    Under CAA section 181(a)(4), an ozone nonattainment area may be 
reclassified to a higher or lower classification (also known as a 
classification bump up or a bump down) ``if an area classified under 
paragraph (1) (Table 1) would have been classified in another category 
if the design value in the area were 5 percent greater or 5 percent 
less than the level on which such classification was based.'' That 
section also states that, ``In making such adjustment, the 
Administrator may consider the number of exceedances of the national 
primary ambient air quality standard for ozone in the area, the level 
of pollution transport between the area and other affected areas, 
including both intrastate and interstate transport, and the mix of 
sources and air pollutants in the area.''
    As noted in the preamble to the rule designating and classifying 
areas following enactment of the CAA Amendments of 1990, the provisions 
of section 181(a)(4) grant the Administrator broad discretion in

[[Page 25781]]

making, or determining not to make, a reclassification. (See 56 FR 
56698; November 6, 1991.) In that designation action, the EPA provided 
criteria to evaluate in determining whether it is appropriate to 
reclassify a particular area. Because CAA section 181(b)(3) provides 
that the EPA must grant any state request to reclassify an area to a 
higher classification, the EPA focused these criteria primarily on how 
the EPA would assess requests for a lower classification. These 
criteria are:
    Request by state: The EPA does not intend to exercise its authority 
to reclassify areas on the EPA's own initiative. Rather, the EPA 
intends to rely on the state to submit a request for a 
reclassification. A tribe may also submit such a request and, in the 
case of a multi-state nonattainment area, all affected states must 
submit the same reclassification request.
    Discontinuity: A 5 percent reclassification must not result in an 
illogical or excessive discontinuity relative to surrounding areas. In 
particular, in light of the area-wide nature of ozone formation, a 
reclassification should not create a ``donut hole'' where an area of 
one classification is surrounded by areas of higher classification.
    Attainment: Evidence should be available that the proposed area 
would be able to attain by the earlier date specified by the lower 
classification in the case of a reclassification downward.
    Emissions reductions: Evidence should be available that the area 
would be very likely to achieve the appropriate total percent emission 
reduction necessary in order to attain in the shorter time period for a 
reclassification downward.
    Trends: Near- and long-term trends in emissions and air quality 
should support a reclassification. Historical air quality data should 
indicate substantial air quality improvement for a reclassification 
downward. Growth projections and emission trends should support a 
reclassification downward. In addition, the EPA will consider whether 
vehicle miles traveled and other indicators of emissions are increasing 
at higher than normal rates.
    Years of data: The same years of ozone air quality data used for 
the initial designation and classification should be used for 
reclassification requests.
    For ozone areas designated in 1991, the EPA approved 
reclassifications when the area met the first requirement (a request by 
the state to EPA) and at least some of the other criteria, and did not 
violate any of the criteria (emissions reductions, trends, etc.). The 
EPA established the same method and criteria for the purpose of 
evaluating any reclassification requests under CAA section 181(a)(4) 
for the 1997 and 2008 ozone NAAQS. The EPA intends to continue to use 
this same approach for purposes of evaluating any requests for a 
reclassification for the 2015 ozone NAAQS. For reclassifications 
downwards, states may only request a reclassification to the next lower 
classification, and air quality data from prior years cannot be used as 
justification to be reclassified to an even lower classification.

A. Five Percent Reclassifications to a Lower Classification

    For an area to be eligible to be reclassified to a lower 
classification under section 181(a)(4), the area's design value must be 
within 5 percent of the upper limit for the next lower classification. 
For example, an area with a Moderate design value of no more than 0.085 
ppm would be eligible to request a reclassification to Marginal because 
0.085 ppm is 5 percent more than the upper limit of 0.081 ppm for the 
Marginal classification. Accordingly, areas with the following design 
values may be eligible to request a reclassification to the next lower 
classification: Moderate areas with a design value of 0.085 ppm or 
less; Serious areas with a design value of 0.097 ppm or less; Severe 
areas with a design value of 0.110 ppm or less; and for Extreme areas 
with a design value of 0.171 ppm or less.

B. Five Percent Reclassifications to a Higher Classification

    An ozone nonattainment area may also be reclassified under section 
181(a)(4) to the next higher classification. As with 5 percent 
reclassifications to a lower classification, the EPA does not intend to 
exercise its authority to reclassify areas to a higher classification 
on the EPA's own initiative. Rather, the EPA intends to rely on the 
state to submit a request for such a reclassification. Under this CAA 
provision, areas with the following design values are eligible to 
request a reclassification to the next higher classification: Marginal 
areas with a design value of 0.076 ppm or more; Moderate areas with a 
design value of 0.088 ppm or more; and Serious areas with a design 
value of 0.099 ppm or more. Note, as discussed Section IX of this 
preamble, under a separate CAA provision, a state may voluntarily 
request that the EPA reclassify a nonattainment area to a higher 
classification at any time and the EPA must approve the request.

C. Timing of the Five Percent Reclassifications

    A Governor or eligible tribal governing body of any area who wishes 
to pursue a reclassification should submit all requests and supporting 
documentation to the EPA Regional Office by July 5, 2018. This 
relatively short time frame is necessary because CAA section 181(a)(4) 
only authorizes the Administrator to make such reclassifications within 
90 days after the initial classification. The EPA will make its 
decision by September 4, 2018.

XI. Determining Rural Transport Areas

    CAA section 182(h) sets out general criteria for determining 
whether an area qualifies as a Rural Transport Area (RTA). The statute 
defines a RTA as an area which is designated nonattainment and neither 
includes nor is adjacent to any part of a metropolitan statistical area 
or consolidated metropolitan statistical area as defined at the time of 
the 1990 CAA amendments. In such cases, the Administrator has 
discretion to treat the area as a RTA based on a finding that the 
emissions within the area do not make a significant contribution to the 
ozone concentrations measured in the area or in other areas. The EPA 
provided guidance on requesting RTA treatment in the February 25, 2016, 
memorandum ``Area Designations for the 2015 Ozone National Ambient Air 
Quality Standards.'' A RTA, regardless of its nonattainment 
classification, is treated as meeting the applicable requirements of 
CAA section 182 (generally relating to submissions required for ozone 
nonattainment areas) if the area meets the submission requirements of a 
Marginal area.
    Two states requested that the EPA find a nonattainment area in 
their state to meet the criteria for treatment as a RTA. In a letter 
dated October 3, 2016, California requested that the EPA make a RTA 
determination for the Tuscan Buttes nonattainment area. In a letter 
dated April 20, 2017, Wisconsin requested that the EPA make a RTA 
determination for the Door County nonattainment area. The EPA has 
determined that the final nonattainment areas for Tuscan Buttes, 
California and Door County, Wisconsin, meet the criteria for treatment 
as RTAs under CAA section 182(h). Documentation supporting these 
determinations are contained in the final TSDs for California (section 
20.0) and Wisconsin (section 3.4), which are available in the public 
docket for this final action. This determination is reflected in the

[[Page 25782]]

regulatory tables in 40 CFR part 81 for each state.

XII. How do designations affect Indian country?

    All state areas listed in the tables at the end of this document 
are designated as indicated, and include Indian country geographically 
located within such areas, except as otherwise noted. Information 
pertaining to areas of Indian country in these tables is intended for 
CAA planning purposes only and is not an EPA determination of Indian 
country land status or any Indian country boundary. The EPA lacks the 
authority to establish Indian country land status, and is making no 
determination of Indian country boundaries in the tables. Consistent 
with the EPA's Tribal Designation Guidance, and at the request of the 
tribes, the EPA is designating certain lands of the Pechanga Tribe and 
the Morongo Tribe in Southern California as separate nonattainment 
areas.\7\ For all other areas, the EPA is designating areas of Indian 
country along with the adjacent/surrounding state area(s). Where 
nonattainment areas include both Indian country and state land, 
coordinated planning will help ensure that the planning decisions made 
by the states and tribes complement each other and that the 
nonattainment area makes progress toward attainment and ultimately 
attains the 2015 ozone NAAQS.
---------------------------------------------------------------------------

at https://www.epa.gov/ozone-designations/epa-guidance-area-designations-2015-ozone-naaqs.
---------------------------------------------------------------------------

XIII. Where can I find information forming the basis for this rule and 
exchanges between the EPA, states, and tribes related to this rule?

    Information providing the basis for this action is provided in the 
docket for this rulemaking. The applicable EPA guidance memoranda and 
copies of correspondence regarding this process between the EPA and the 
states, tribes, and other parties are available for review at the EPA 
Docket Center listed above in the addresses section of this document, 
and on the EPA's ozone designation website at https://www.epa.gov/ozone-designations. State-specific information is available from the 
EPA Regional Offices at the addresses at the top of this Preamble.

XIV. Environmental Justice Concerns

    When the EPA establishes a new or revised NAAQS, the CAA requires 
the EPA to designate all areas of the U.S. as either nonattainment, 
attainment, or unclassifiable. This final action addresses designation 
determinations for the 2015 ozone NAAQS. In addition, nonattainment 
areas are being classified according to the severity of their ozone air 
quality problems. Area designations address environmental justice 
concerns by ensuring that the public is properly informed about the air 
quality in an area. In locations where air quality does not meet the 
NAAQS, the CAA requires relevant state authorities to initiate 
appropriate air quality management actions to ensure that all those 
residing, working, attending school, or otherwise present in those 
areas are protected, regardless of minority and economic status.

XV. Statutory and Executive Order Reviews

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

    This action is exempt from review by the Office of Management and 
Budget because it responds to the CAA requirement to promulgate air 
quality designations after promulgation of a new or revised NAAQS.

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

    This action is not an Executive Order 13771 regulatory action 
because actions such as air quality designations after promulgating a 
new revised NAAQS are exempt from review under Executive Order 12866.

C. Paperwork Reduction Act (PRA)

    This action does not impose an information collection burden under 
the PRA. This action fulfills the non-discretionary duty for the EPA to 
promulgate air quality designations after promulgation of a new or 
revised NAAQS and does not contain any information collection 
activities.

D. Regulatory Flexibility Act (RFA)

    This designation action under CAA section 107(d) is not subject to 
the RFA. The RFA applies only to rules subject to notice-and-comment 
rulemaking requirements under the APA, 5 U.S.C. 553, or any other 
statute. Section 107(d)(2)(B) of the CAA explicitly provides that 
designations are exempt from the notice-and-comment provisions of the 
APA. In addition, designations under CAA section 107(d) are not among 
the list of actions that are subject to the notice-and-comment 
rulemaking requirements of CAA section 307(d).

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

F. Executive Order 13132: Federalism

    This action does not have federalism implications. It will not have 
substantial direct effects on the states, on the relationship between 
the national government and the states, or on the distribution of power 
and responsibilities among the various levels of government. The 
division of responsibility between the federal government and the 
states for purposes of implementing the NAAQS is established under the 
CAA.

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

    This action has tribal implications. However, it will neither 
impose substantial direct compliance costs on federally recognized 
tribal governments, nor preempt tribal law.
    The EPA consulted with tribal officials early in the process of 
developing this regulation to permit them to have meaningful and timely 
input into its development. At the beginning of the designations 
process, letters were sent to all tribes who were expected to be 
impacted by designations for the 2015 ozone NAAQS. These letters not 
only informed the tribes of the overall designations process, but also 
offered the tribes consultation to ensure early communication and 
coordination. Additionally, letters were sent to potentially affected 
tribes indicating the EPA's intended designations for their areas of 
Indian country. To the extent possible, the EPA included the tribes' 
input into the final decision-making process for designations of their 
areas of Indian country for the 2015 ozone NAAQS.

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

    The EPA interprets Executive Order 13045 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

[[Page 25783]]

environmental standard intended to mitigate health or safety risks.

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

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

J. National Technology Transfer and Advancement Act (NTTAA)

    This rulemaking does not involve technical standards.

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

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

L. Congressional Review Act (CRA)

    This action is subject to the CRA, and the EPA will submit a rule 
report to each House of the Congress and to the Comptroller General of 
the U.S. This action is not a ``major rule'' as defined by 5 U.S.C. 
804(2).

M. Judicial Review

    Section 307(b)(1) of the CAA indicates which Federal Courts of 
Appeal have venue for petitions for review of final actions by the EPA. 
This section provides, in part, that petitions for review must be filed 
in the Court of Appeals for the District of Columbia Circuit for: (i) 
``any nationally applicable regulations promulgated, or final actions 
taken, by the Administrator,'' or (ii) when such action is locally or 
regionally applicable, ``if such action is based on a determination of 
nationwide scope or effect and if in taking such action the 
Administrator finds and publishes that such action is based on such a 
determination.''
    This rule that designates areas for the 2015 ozone NAAQS is 
``nationally applicable'' within the meaning of CAA section 307(b)(1). 
This rule establishes designations for areas across the U.S. for the 
2015 ozone NAAQS. At the core of this rulemaking is the EPA's 
interpretation of the designation provisions in section 107(d)(1) of 
the CAA, and its application of that interpretation to areas across the 
country.
    For these reasons, the Administrator also is determining that the 
final designations are of nationwide scope and effect for the purposes 
of CAA section 307(b)(1). This is particularly appropriate because, in 
the report on the 1977 Amendments that revised section 307(b)(1) of the 
CAA, Congress noted that the Administrator's determination that an 
action is of ``nationwide scope or effect'' would be appropriate for 
any action that has a scope or effect beyond a single judicial circuit. 
H.R. Rep. No. 95-294 at 323, 324, reprinted in 1977 U.S.C.C.A.N. 1402-
03. Here, the scope and effect of this rulemaking extends to numerous 
judicial circuits since the designations apply to areas across the 
country. In these circumstances, CAA section 307(b)(1) and its 
legislative history calls for the Administrator to find the rule to be 
of ``nationwide scope or effect'' and for venue to be in the District 
of Columbia Circuit.
    Thus, any petitions for review of these final designations must be 
filed in the Court of Appeals for the District of Columbia Circuit 
within 60 days from the date of this final action is published in the 
Federal Register.
