SUPPLEMENTARY INFORMATION: 

I. Background

    On October 1, 2015, the EPA revised both the primary and secondary 
NAAQS for ozone to a level of 0.070 parts per million (ppm) (annual 
fourth-highest daily maximum 8-hour average concentration, averaged 
over 3 years).\1\ The revised 2015 ozone NAAQS provide greater 
protection of public health and the environment than the previous 2008 
ozone NAAQS. Although the 2015 ozone NAAQS retain the same general form 
and averaging time as the 0.75 ppm NAAQS set in 2008, the level is more 
protective.
---------------------------------------------------------------------------

    \1\ 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.
---------------------------------------------------------------------------

II. Purpose of This Action

    The purpose of this action is to announce and promulgate initial 
area designations for most counties \2\ in the country and most areas 
of Indian country with respect to the 2015 primary and secondary NAAQS 
for ozone, in accordance with the requirements of CAA section 107(d). 
The EPA is designating these counties as either Attainment/
Unclassifiable or Unclassifiable. For other areas not addressed in this 
final rule, the EPA is not extending the time provided under section 
107(d)(1)(B) of the Clean Air Act but is not yet prepared to issue 
designations. The agency intends to address these areas in a separate 
future action.
---------------------------------------------------------------------------

    \2\ 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 United States.
---------------------------------------------------------------------------

    In this action, the EPA is designating as Attainment/Unclassifiable 
2,646 counties for which the states recommended a designation of 
Attainment or Attainment/Unclassifiable. These are counties with one or 
more monitors attaining the 2015 ozone NAAQS or counties for which the 
EPA does not have reason to believe are violating the 2015 ozone NAAQS 
or are contributing to a violation of the 2015 ozone NAAQS in another 
county.
    In addition, the state of Washington recommended a designation of 
Unclassifiable for three counties--Benton, Franklin, and Walla Walla. 
Benton County and Franklin County are part of the Kennewick Richland, 
Washington, CBSA.\3\ Walla Walla County is outside of the Kennewick-
Richland, Washington, CBSA, but adjacent to Benton County, and the 
state of Washington recommended it to be included in the Unclassifiable 
area. A monitor was installed in 2015 in Benton County, Washington. 
Three consecutive years of certified ozone monitoring data to determine 
the counties' attainment status is not currently available and would 
not be available if the EPA were to extend the deadline for designating 
this area until October 2018. Thus, EPA is designating this area as 
Unclassifiable, consistent with the state's recommendation.\4\

2015 National Ambient Air Quality Standards for Ozone,'' letter from 
Maria D. Bellon, Director, Department of Ecology, State of 
Washington, to Dennis McLerran, Regional Administrator, Region 10, 
dated September 30, 2016.
    \4\ See ``Washington Area Designation for the 2015 Ozone 
National Ambient Air Quality Standards Technical Support Document, 
dated September 29, 2017.
---------------------------------------------------------------------------

    Consistent with the EPA's ``Policy for Establishing Separate Air 
Quality Designations for Areas of Indian Country'' (December 20, 2011), 
the EPA is designating two areas of Indian country (Fond du Lac Band of 
Lake Superior Chippewa Indians and Forest County Potawatomi Community) 
as separate Attainment/Unclassifiable areas.\5\ Both the Fond du Lac 
Band of Lake Superior Chippewa Indians and the Forest County Potawatomi 
submitted attainment recommendations

based on air quality data from ozone monitors located on their 
respective tribal lands.

    \5\ Memorandum from Stephen D. Page, Director, Office of Air 
Quality Planning and Standards, to Regional Air Directors, Regions 
I-X, dated December 20, 2011, titled, ``Policy for Establishing 
Separate Air Quality Designations for Areas of Indian Country.''
---------------------------------------------------------------------------

III. Public Participation in the Designation Process

    Section 107(d)(2)(B) of the CAA provides that initial area 
designations under CAA section 107(d)(1) are not subject to the notice-
and-comment rulemaking procedures of the Administrative Procedure Act 
(APA), but that ``nothing herein shall be construed as precluding such 
public notice and comment whenever possible.'' The EPA is promulgating 
these designations for 2,649 counties including Indian Country located 
in those counties, two separate areas of Indian Country, and five 
territories without notice-and-comment, because we believe that the 
designations pursuant to this final action are noncontroversial and the 
designations are consistent with the recommendations of the states and 
tribes in which these counties and tribal lands are located. Any party 
that is concerned about one or more of the area designations finalized 
in this action may file a petition for reconsideration with the 
Administrator.

IV. 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, a few areas in the Western U.S. have experienced 
high levels of ozone in the wintertime. Ozone and ozone precursors can 
be transported to an area from sources in nearby areas or from sources 
located hundreds of miles away.

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

    As discussed in Section I of this preamble, on October 1, 2015, the 
EPA revised both the primary and secondary NAAQS for ozone to a level 
of 0.070 ppm (annual fourth-highest daily maximum 8-hour average 
concentration, averaged over 3 years) to provide increased protection 
of public health and the environment.
    The EPA lowered the primary 8-hour ozone standard from 0.075 ppm to 
0.070 ppm to protect against health effects associated with ozone 
exposure, including a number of harmful effects on the respiratory 
system, including difficulty breathing, inflammation of the airways, 
and aggravation of lung diseases such as asthma and chronic obstructive 
pulmonary disease, and increased premature death from heart or lung 
disease. The EPA also revised the level of the secondary 8-hour ozone 
standard from 0.075 ppm to 0.070 ppm to protect against welfare 
effects, including impacts on sensitive vegetation and forested 
ecosystems.

VI. CAA Requirements

    When the EPA promulgates a new or revised NAAQS, the EPA is 
required to designate areas 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, then 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 
designates most areas that do not meet the definition of Nonattainment 
as ``Unclassifiable/Attainment.'' In a few instances, based on 
circumstances where some monitoring data are available but is 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 by the CAA to recommend air 
quality designations, including the appropriate boundaries for areas, 
to the EPA. 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 definitions of 
nonattainment, attainment and unclassifiable, 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 standards for the 
pollutant, and 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.\6\
---------------------------------------------------------------------------

    \6\ 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

[[Page 54234]]

submit designation recommendations to the EPA.

VII. Environmental Justice Concerns

    When the EPA establishes a new or revised NAAQS, the CAA requires 
the EPA to designate all areas of the United States as either 
nonattainment, attainment, or unclassifiable. This final action 
addresses designation determinations for 2,649 counties including 
Indian Country located in those counties, two separate areas of Indian 
country, and five territories for the 2015 ozone NAAQS. 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.

VIII. 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 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 Government

    This action does not have tribal implications. It will neither 
impose substantial direct compliance costs on federally recognized 
tribal governments, nor preempt tribal law. The CAA provides for states 
and eligible tribes to develop plans to regulate emissions of air 
pollutants within their areas, as necessary, based on the designations. 
The TAR provides tribes the opportunity to apply for eligibility to 
develop and implement CAA programs, such as programs to attain and 
maintain the ozone NAAQS, but it leaves to the discretion of the tribe 
the decision of whether to apply to develop these programs and which 
programs, or appropriate elements of a program, the tribe will seek to 
adopt. This rule does not have a substantial direct effect on one or 
more Indian tribes.

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 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 VII 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 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

[[Page 54235]]

CAA, and its application of that interpretation to areas across the 
country.
    For the same 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 final designations must be filed 
in the Court of Appeals for the District of Columbia Circuit within 60 
days from the date final action is published in the Federal Register.
