Air Quality Designations for the 2008 

Ozone National Ambient Air Quality 

Standards 

AGENCY: Environmental Protection 

Agency (EPA). 

ACTION: Final rule. 

SUMMARY: This rule establishes initial 

air quality designations for most areas in 

the United States, including areas of 

Indian country, for the 2008 primary 

and secondary national ambient air 

quality standards (NAAQS) for ozone. 

The designations for several counties in 

Illinois, Indiana, and Wisconsin that the 

EPA is considering for inclusion in the 

Chicago nonattainment area will be 

designated in a subsequent action, no 

later than May 31, 2012. 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. The EPA 

is establishing the air quality thresholds 

that define the classifications in a 

separate rule that the EPA is signing and 

publishing in the Federal Register on 

the same schedule as these designations. 

In accordance with that separate rule, 

six nonattainment areas in California are 

being reclassified to a higher 

classification. 

DATES: The effective date of this rule is 

July 20, 2012. 

ADDRESSES: The EPA has established a 

docket for this action under Docket ID

II. What is the purpose of this action? 

The purpose of this action is to 

announce and promulgate initial area 

designations for most areas of the 

country with respect to the 2008 

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, 

unclassifiable, or unclassifiable/ 

attainment. In addition, the 

nonattainment areas are classified by 

operation of law according to the 

severity of their ozone air quality 

problems and six areas in California are 

being reclassified immediately to a 

higher classification. The classification 

categories are Marginal, Moderate, 

Serious, Severe, and Extreme. The EPA 

is establishing the air quality thresholds 

that define the classifications in a 

separate rule titled, ‘‘Implementation of 

the 2008 National Ambient Air Quality 

Standards for Ozone: Nonattainment 

Area Classifications Approach, 

Attainment Deadlines and Revocation of 

the 1997 Ozone Standards for 

Transportation Conformity Purposes’’ 

(Classifications Rule). In that separate 

rule, the EPA also codified the 

immediate reclassification of six areas 

in California. (See 40 CFR 51.1103(d).) 

The list of all areas being designated in 

each state and in areas of Indian county 

appear in the tables at the end of this 

final rule (amendments to 40 CFR 

81.301–356). For areas designated as 

nonattainment, the tables include the 

area’s classification by operation of law 

or the area’s reclassification in 

accordance with 40 CFR 51.1103(d). 

In this action, the EPA is designating 

45 areas as nonattainment. Seven of the 

areas are multi-state areas. The EPA is 

designating one area, Uinta Basin, WY, 

as unclassifiable because there is 

existing non-regulatory monitoring in 

the area that detected levels of ozone 

that exceed the NAAQS. Regulatory 

monitoring has been conducted in that 

area since April 2011, and thus there are 

not yet three consecutive years of 

certified ozone monitoring data 

available that can be used to determine 

the area’s attainment status. Consistent 

with previous initial area designations 

for ozone, the EPA is designating all the 

remaining state areas and Indian 

country as unclassifiable/attainment. 

Consistent with the EPA’s ‘‘Policy for 

Establishing Separate Air Quality 

Designations for Areas of Indian 

Country’’ (December 20, 2011), the EPA 

is designating four areas of Indian 

country separately from their adjacent/ 

surrounding state areas.1 The lands of 

the Pechanga Tribe and the Morongo 

Tribe in Southern California are being 

designated as separate nonattainment 

areas, while two additional areas in 

Indian country are being designated as 

separate unclassifiable/attainment areas. 

The EPA is basing the designations on 

the most recent certified ozone air 

quality monitoring data and 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 the CAA. Requirements 

vary according to an area’s 

classification. The EPA will be 

proposing shortly an implementation 

rule to assist states in the development 

of state implementation plans for 

attaining the ozone standards. 

III. What is ozone and how is it formed? 

Ground-level ozone, O3, 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 high elevation areas in the Western 

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 2008 ozone NAAQS 

and the health and welfare concerns 

they address? 

On March 12, 2008, the EPA revised 

both the primary and secondary NAAQS 

for ozone to a level of 0.075 parts per 

million (ppm) (annual fourth-highest 

daily maximum 8-hour average 

concentration, averaged over 3 years) to 

provide increased protection of public 

health and the environment.2 The 2008 

ozone NAAQS retains the same general 

form and averaging time as the 0.08 

ppm NAAQS set in 1997, but is set at 

a more protective level. 

Ozone exposure also has been 

associated with increased susceptibility 

to respiratory infections, medication use 

by asthmatics, doctor visits, and 

emergency department visits and

hospital admissions for individuals with 

respiratory disease. Ozone exposure 

may also contribute to premature death, 

especially in people with heart and lung 

disease. The secondary ozone standard 

was revised to protect against adverse 

welfare effects including impacts to 

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 areas as nonattainment, 

attainment, or unclassifiable, pursuant 

to section 107(d)(1) of the CAA. The 

CAA requires the EPA to complete the 

initial area designation process within 2 

years of promulgating the 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. 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 designations that did not meet 

the statutory requirements or were 

otherwise inconsistent with the facts or 

analysis deemed appropriate by the 

EPA. If the EPA is considering 

modifications to a state’s initial 

recommendation, the EPA is required to 

notify the state of any such intended 

modifications to its recommendation 

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, it then has an 

opportunity to respond to the EPA to 

demonstrate why it believes the 

modification proposed by the EPA is 

inappropriate. Even if a state fails to 

provide any recommendation for an 

area, in whole or in part, the EPA still 

must promulgate a designation that the 

Administrator deems appropriate. 

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.’’ 

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 the remaining areas 

as ‘‘unclassifiable/attainment’’ 

indicating that the areas either have 

attaining air quality monitoring data or 

that air quality information is not 

available because the areas are not 

monitored, and the EPA has not 

determined that the areas contribute to 

a violation in a nearby area. 

The EPA believes that section 107(d) 

provides the agency with discretion to 

determine how best to interpret the 

terms ‘‘contributes to’’ and ‘‘nearby’’ in 

the definition of a nonattainment area 

for a new or revised NAAQS, given 

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. In 

particular, the EPA believes that the 

statute does not require the agency to 

establish bright line tests or thresholds 

for what constitutes ‘‘contribution’’ or 

‘‘nearby’’ for purposes of designations.3

Similarly, the EPA believes that the 

statute permits the EPA to evaluate the 

appropriate application of the term 

‘‘area’’ as may be appropriate for a 

particular NAAQS. 

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? 

Within one year after a new or revised 

air quality standard is established, the 

CAA requires the governor of each state 

to submit to the EPA a list of all areas 

in the state, with recommendations for 

whether each area meets the standard. 

On December 4, 2008, the EPA issued 

guidance for states and tribal agencies to 

use for this purpose. (See memorandum 

from Robert J. Meyers, Principal Deputy 

Assistant Administrator, to Regional 

Administrators, Regions I–X, titled, 

‘‘Area Designations for the 2008 Revised 

Ozone National Ambient Air Quality 

Standards.) The guidance provided the 

anticipated timeline for designations 

and identified important factors that the 

EPA recommended states and tribes 

consider in making their 

recommendations. These factors include 

air quality data, emissions data, traffic 

and commuting patterns, growth rates 

and patterns, meteorology, geography/ 

topography, and jurisdictional 

boundaries. In the guidance, the EPA 

asked that states and tribes submit their 

designation recommendations, 

including appropriate area boundaries, 

to the EPA by March 12, 2009. Later in 

the process, the EPA issued 2 new 

guidance memoranda related to 

designating areas of Indian county. (See 

December 20, 2011, memorandum from 

Stephen D. Page, 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.’’) 

Under the initial schedule, the EPA 

intended to complete the initial 

designations for the 2008 ozone NAAQS 

on a 2-year schedule, by March 12, 

2010. On September 16, 2009, the EPA 

announced that it would initiate a 

rulemaking to reconsider the 2008 

ozone NAAQS for various reasons, 

including the fact that the 0.075 ppm 

level fell outside of the range 

recommended by the Clean Air 

Scientific Advisory Committee, the 

independent group that provides advice 

to the EPA Administrator on the 

technical bases for the EPA’s NAAQS. 

The EPA signed the proposed 

reconsideration on January 6, 2010. (See 

75 FR 2938; January 19, 2010.) Because 

of the significant uncertainty the ozone 

NAAQS reconsideration created 

regarding the continued applicability of 

the 2008 NAAQS, the EPA determined 

there was insufficient information to 

mstockstill on DSK4VPTVN1PROD with RULES2

Federal Register / Vol. 77, No. 98 / Monday, May 21, 2012 / Rules and Regulations 30091 

4The 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 I. 

designate areas within 2 years of 

promulgation of the NAAQS. Therefore, 

the EPA used its authority under CAA 

section 107(d)(1)(B) to extend the 

deadline for designating areas by 1 year, 

until March 12, 2011. (See 75 FR 2936; 

January 19, 2010.) The EPA has not 

taken final action on the proposed 

reconsideration; thus, the current 

NAAQS for ozone remains at 0.075 

ppm, as established in 2008. 

After the March 12, 2011, designation 

deadline passed, WildEarth Guardians 

and Elizabeth Crowe (WildEarth 

Guardians) filed a lawsuit seeking to 

compel the EPA to take action to 

designate areas for the 2008 ozone 

NAAQS. WildEarth Guardians and 

Elizabeth Crowe v. Jackson (D. Ariz. 11– 

CV–01661). The EPA and WildEarth 

Guardians settled the case by entering 

into a consent decree that requires the 

EPA Administrator to sign a final rule 

designating areas for the 2008 ozone 

NAAQS by May 31, 2012. 

On September 22, 2011, the EPA 

issued a memorandum to clarify for 

state and local agencies the status of the 

2008 ozone NAAQS and to outline 

plans for moving forward to implement 

them. The EPA indicated that it would 

proceed with initial area designations 

for the 2008 NAAQS, and planned to 

use the recommendations states made in 

2009 as updated by the most current, 

certified air quality data from 2008– 

2010. While the EPA did not request 

that states submit updated designation 

recommendations, the EPA provided the 

opportunity for states to do so. Several 

states chose to update their 

recommendations, and some requested 

that the EPA base designations for their 

areas on certified air quality data from 

2009–2011, and committed to certify the 

2011 data earlier than the May 1 

deadline for annual air monitoring 

certification under 40 CFR part 

58.15(a)(2) so that the EPA would have 

sufficient time to consider the data in 

making decisions on designations and 

nonattainment area boundaries. 

On or about December 9, 2011, the 

EPA sent letters to Governors and Tribal 

leaders notifying them of the EPA’s 

preliminary response to their 

designation recommendations and to 

inform them of the EPA’s approach for 

completing the designations for the 

2008 ozone NAAQS. The EPA requested 

that states submit any additional 

information that they wanted the EPA to 

consider by February 29, 2011, 

including any certified 2011 air quality 

monitoring data. On January 31, 2011, 

the EPA sent revised 120-day letter 

responses to Illinois, Indiana, and 

Wisconsin based on updated ozone air 

quality data for 2009–2011, submitted 

by the state of Illinois two days before 

the EPA sent the December 9, 2011, 

letters. Given the timing of Illinois’ 

submission of certified data, EPA was 

not able to consider the information in 

the December 9, 2011, letters. After 

reviewing the new information, which 

indicated a violation of the ozone 

NAAQS at a monitor in the Chicago 

area, the EPA sent letters on January 31, 

2012 notifying Illinois, Indiana, and 

Wisconsin that it intended to designate 

certain counties, identified in those 

letters, as nonattainment for the 2008 

ozone NAAQS. The EPA cannot finalize 

a designation for those areas until 120 

days following the letters. Therefore, the 

EPA will be designating the Illinois, 

Indiana, and Wisconsin counties 

identified in the January 31, 2011, 

letters in a separate rule that will be 

signed no later than May 31, 2012. 

Although not required by section 

107(d) of the CAA, the EPA also 

provided an opportunity for members of 

the public to comment on the EPA’s 

120-day response letters to states and 

tribes. The EPA announced a 30-day 

public comment period in the Federal 

Register on December 20, 2011 (76 FR 

78872). The comment period was 

subsequently extended until February 3, 

2012 (77 FR 2677; January 19, 2012). On 

February 14, 2012 (77 FR 8211), the EPA 

reopened the public comment period for 

the limited purpose of inviting comment 

on the EPA’s revised responses to 

Illinois, Indiana, and Wisconsin. State 

and tribal recommendations and the 

EPA’s preliminary responses were 

posted on EPA’s Web site at http:// 

www.epa.gov/ozonedesignations 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 in the docket. 

VII. What air quality data has the EPA 

used to designate areas for the 2008 

ozone NAAQS? 

The final ozone designations are 

based primarily on certified air quality 

monitoring data from calendar years 

2008–2010, which was the most recent 

certified data available to the EPA 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. States 

generally had not completed these 

requirements for calendar year 2011 

ozone air quality data when the EPA 

notified states of our intended 

designations on December 9, 2011. In 

certain cases, states included as part of 

their designation recommendations a 

request that the EPA consider 

monitoring data from 2009–2011 in 

making final designation decisions. In 

these requests, they indicated to the 

EPA what they expected their certified 

ozone air quality data would show 

regarding whether an area was attaining 

the standard, and for designations 

purposes they committed to certifying 

their 2011 data no later than February 

29, 2012, so that the EPA would have 

sufficient time to consider it. Thus, for 

those areas, the EPA considered the 

state’s preliminary representation of 

2011 data in sending the 120-day 

notification letter. We have verified 

these representations in making our 

final designations decisions. 

VIII. What are the ozone air quality 

classifications? 

In accordance with CAA section 

181(a)(1), each area designated as 

nonattainment for the 2008 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).4 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. The final Classifications 

Rule, which is being signed at the same 

time as the designations rule and being 

published and effective at the same time 

or before the designations, establishes 

the classification thresholds for each 

classification category for purposes of 

the 2008 NAAQS and explains the 

EPA’s methodology for calculating the 

thresholds. In addition, in the 

mstockstill on DSK4VPTVN1PROD with RULES2

30092 Federal Register / Vol. 77, No. 98 / Monday, May 21, 2012 / Rules and Regulations 

Classifications Rule, the EPA 

promulgated a regulation, 40 CFR 

51.1103(d), that immediately reclassifies 

6 areas in California to higher 

classifications. The classification for 

each nonattainment area designated for 

the 2008 ozone NAAQS is shown in the 

40 CFR part 81 tables at the end of this 

designations rule. 

IX. What is the reclassification of six 

California nonattainment areas? 

The final Classifications Rule 

addresses the reclassification for the 

2008 ozone NAAQS of selected areas in 

California that had voluntarily 

reclassified under the 1997 ozone 

NAAQS. In accordance with the final 

Classifications Rule, the following areas 

are being voluntarily reclassified to a 

higher classification for purposes of the 

2008 NAAQS pursuant to that rule: 

Serious—Ventura County, CA; Severe— 

Los Angeles-San Bernardino Counties 

(West Mojave Desert), Riverside County 

(Coachella Valley), and Sacramento 

Metro, CA; Extreme—Los Angeles-South 

Coast Air Basin, and San Joaquin Valley, 

CA. These classifications are reflected in 

the tables at the end of this final rule 

(amendments to 40 CFR 81.301–356). 

X. Can states request that areas 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.’’ The 

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 section 

181(a)(4) provisions grant the 

Administrator broad discretion in 

making or determining not to make, a 

reclassification. (See 56 FR 56698; 

November 6, 1991.) As part of the 1991 

action, the EPA developed criteria to 

evaluate whether it is appropriate to 

reclassify a particular area. (See list 

below and at 56 FR 56698.) Because 

section 181(b)(3) provides that the EPA 

must grant any state request to reclassify 

an area into a higher classification, the 

EPA focused these criteria primarily on 

how the EPA would assess requests for 

a lower classification. In 1991, 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 used 

the same method and criteria once again 

to evaluate reclassification requests 

under section 181(a)(4) for purposes of 

the 1997 ozone NAAQS. The EPA 

intends to continue to use this same 

approach for purposes of evaluating any 

request for a reclassification for the 2008 

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. 

The criteria EPA intends to use to 

evaluate whether it is appropriate to 

reclassify a particular area include: 

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 five 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, we 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. 

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 five 

percent of the upper limit for the next 

lower classification. For example, an 

area with a Moderate design value of 

0.090 ppm (or less) would be eligible to 

request a reclassification to Marginal 

because 0.090 ppm is five percent more 

than the upper limit of 0.086 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 0.090 ppm or less; 

Serious areas with a design value of 

0.105 ppm or less; and Severe areas 

with a design value of 0.118 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 five 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. Areas 

with the following design values are 

eligible to request a reclassification to 

the next higher classification: Marginal 

areas with a design value of 0.082 ppm 

or more; Moderate areas with a design 

value of 0.095 ppm or more; and Serious 

areas with a design value of 0.108 ppm 

or more. 

C. Timing of the Five Percent 

Reclassifications 

A Governor or eligible Tribal 

governing body of any area that wishes 

to pursue a reclassification should 

submit all requests and supporting 

documentation to the EPA Regional 

Office by June 20, 2012. This relatively 

short time frame is necessary because 

section 181(a)(4) only authorizes the 

Administrator to make such 

mstockstill on DSK4VPTVN1PROD with RULES2

Federal Register / Vol. 77, No. 98 / Monday, May 21, 2012 / Rules and Regulations 30093 

reclassifications within 90 days after the 

initial classification. 

XI. 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. 

In general, state recommendations for 

initial area designations do not apply to 

Indian country. Consistent with the 

‘‘Policy for Establishing Separate Air 

Quality Designations for Areas of Indian 

Country’’ (December 20, 2011), in 

instances where the EPA did not receive 

an initial designation recommendation 

from a tribe, the EPA is designating their 

area of Indian country along with the 

adjacent/surrounding state area(s). 

Tribes whose areas of Indian country are 

designated as nonattainment for the 

2008 ozone NAAQS are being affected 

by poor air quality. Where 

nonattainment areas include both 

Indian country and state land, it is 

important for states and tribes to work 

together to coordinate planning efforts. 

Coordinated planning will help ensure 

that the planning decisions made by the 

states and tribes complement each other 

and that the nonattainment area makes 

reasonable progress toward attainment 

and ultimately attains the 2008 ozone 

NAAQS. 

XII. 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 are 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 Web site at http:// 

www.epa.gov/ozonedesignations. Statespecific information is available from 

the EPA Regional Offices. 

XIII. Statutory and Executive Order 

Reviews 

Upon promulgation of a new or 

revised NAAQS, the CAA requires the 

EPA to designate areas as attaining or 

not attaining the NAAQS. The CAA 

then specifies requirements for areas 

based on whether such areas are 

attaining or not attaining the NAAQS. In 

this final rule, the EPA assigns 

designations to areas as required. 

A. Executive Order 12866: Regulatory 

Planning and Review and Executive 

Order 13563: Improving Regulation and 

Regulatory Review 

This action responds to the CAA 

requirement to promulgate air quality 

designations after promulgation of a 

new or revised NAAQS. This type of 

action is exempt from review under 

Executive Orders 12866 (58 FR 51735, 

October 4, 1993) and 13563 (76 FR 3821, 

January 21, 2011). 

B. Paperwork Reduction Act 

This action does not impose an 

information collection burden under the 

provisions of the Paperwork Reduction 

Act, 44 U.S.C. 3501 et seq. Burden is 

defined at 5 CFR 1320.3(b). This rule 

responds to the CAA requirement to 

promulgate air quality designations after 

promulgation of a new or revised 

NAAQS. This requirement is prescribed 

in the CAA section 107. The present 

final rule does not establish any new 

information collection requirements. 

C. Regulatory Flexibility Act 

This final rule is not subject to the 

Regulatory Flexibility Act (RFA), which 

generally requires an agency to prepare 

a regulatory flexibility analysis for any 

rule that will have a significant 

economic impact on a substantial 

number of small entities. The RFA 

applies only to rules subject to noticeand-comment rulemaking requirements 

under the Administrative Procedure Act 

(APA) or any other statute. This rule is 

not subject to notice-and-comment 

requirements as provided under CAA 

section 107(d)(2)(B). 

D. Unfunded Mandates Reform Act 

This action contains no federal 

mandate under the provisions of Title II 

of the Unfunded Mandates Reform Act 

of 1995 (UMRA), 2 U.S.C. 1531–1538 for 

state, local, or tribal governments or the 

private sector. The action imposes no 

enforceable duty on any state, local or 

tribal governments or the private sector. 

Therefore, this action is not subject to 

the requirements of sections 202 and 

205 of the UMRA. 

This action is also not subject to the 

requirements of section 203 of UMRA 

because it contains no regulatory 

requirements that might significantly or 

uniquely affect small governments. It 

does not create any additional 

requirements beyond those of the CAA 

and ozone NAAQS (40 CFR 50.15). The 

CAA establishes the process whereby 

states take primary responsibility in 

developing plans to meet the ozone 

NAAQS. 

E. Executive Order 13132: Federalism 

This final rule 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, as specified in 

Executive Order 13132. The CAA 

establishes the process whereby states 

take primary responsibility in 

developing plans to meet the ozone 

NAAQS. This rule will not modify the 

relationship of the states and the EPA 

for purposes of developing programs to 

implement the ozone NAAQS. Thus, 

Executive Order 13132 does not apply 

to this rule. 

F. Executive Order 13175: Consultation 

and Coordination With Indian Tribal 

Governments 

Subject to the Executive Order 13175 

(65 FR 67249, November 9, 2000) the 

EPA may not issue a regulation that has 

tribal implications, that imposes 

substantial direct compliance costs, and 

that is not required by statute, unless 

the Federal government provides the 

funds necessary to pay the direct 

compliance costs incurred by tribal 

governments, or the EPA consults with 

tribal officials early in the process of 

developing the proposed regulation and 

develops a tribal summary impact 

statement. 

The EPA has concluded that this 

action may have tribal implications. 

However, it will neither impose 

substantial direct compliance costs on 

tribal governments, nor preempt tribal 

law. Tribes whose areas of Indian 

country are being designated as 

‘‘nonattainment’’ for the 2008 ozone 

NAAQS are affected by poor air quality. 

Although tribes are not required to 

submit implementation plans under the 

Clean Air Act, for those tribes whose 

areas are being designated as part of 

surrounding state areas, it will be 

imperative that states and the tribes 

coordinate on air quality planning 

efforts to ensure that ozone levels are 

reduced. In addition, several tribes’ 

areas of Indian country are being 

designated as ‘‘nonattainment’’ 

separately from their surrounding state 

areas. For these tribes, internal capacity 

for air quality planning will be 

important to enable their areas of Indian 

country to come into attainment. 

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, 

mstockstill on DSK4VPTVN1PROD with RULES2

30094 Federal Register / Vol. 77, No. 98 / Monday, May 21, 2012 / Rules and Regulations 

letters were sent to all tribes who were 

expected to be impacted by designations 

for the 2008 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. These letters offered an 

additional opportunity for consultation. 

All consultations were completed in late 

February/early April 2012. During 

consultation, the primary concerns 

raised by tribes included the following: 

Impact of nonattainment designation on 

future economic development; 

appropriateness of using data from 

monitors not on tribal land; and 

ensuring final decisions are consistent 

with the EPA’s ‘‘Policy for Establishing 

Separate Air Quality Designations for 

Areas of Indian Country.’’ (December 

20, 2011). During the consultations, the 

EPA’s Regional Offices ensured that the 

tribes fully understood the reasoning for 

the EPA’s preliminary designations 

decisions and how those decisions are 

aligned with a consideration of the most 

recent certified air quality data and all 

other relevant information, including 

the EPA’s ‘‘Policy for Establishing 

Separate Air Quality Designations for 

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 2008 ozone 

NAAQS. 

G. Executive Order 13045: Protection of 

Children From Environmental Health 

and Safety Risks 

The EPA interprets Executive Order 

13045 (62 FR 19885, April 23, 1997) as 

applying only to those regulatory 

actions that concern health or safety 

risks, such that the analysis required 

under section 5–501 of the Executive 

Order has the potential to influence the 

regulation. This action is not subject to 

Executive Order 13045 because it does 

not establish an environmental standard 

intended to mitigate health or safety 

risks. 

H. Executive Order 13211: Actions That 

Significantly Affect Energy Supply, 

Distribution, or Use 

This action is not subject to Executive 

Order 13211 (66 FR 28355 (May 22, 

2001)), because it is not a significant 

regulatory action under Executive Order 

12866. 

I. National Technology Transfer and 

Advancement Act (NTTAA) 

Section 12(d) of the NTTAA of 1995, 

Public Law 104–113, section 12(d) (15 

U.S.C. 272 note) directs the EPA to use 

voluntary consensus standards (VCS) in 

its regulatory activities unless to do so 

would be inconsistent with applicable 

law or otherwise impracticable. 

Voluntary consensus standards are 

technical standards (e.g., materials 

specifications, test methods, sampling 

procedures, and business practices) that 

are developed or adopted by VCS 

bodies. The NTTAA directs the EPA to 

provide Congress, through the Office of 

Management and Budget, explanations 

when the Agency decides not to use 

available and applicable VCS. 

This action does not involve technical 

standards. Therefore, the EPA did not 

consider the use of any VCS. 

J. Executive Order 12898: Federal 

Actions To Address Environmental 

Justice in Minority Populations and 

Low-Income Populations. 

Executive Order 12898 (59 FR 7629 

(Feb. 16, 1994)) establishes federal 

executive policy on environmental 

justice. Its main provision directs 

federal agencies, to the greatest extent 

practicable and permitted by law, to 

make environmental justice part of their 

mission by identifying and addressing, 

as appropriate, disproportionately high 

and adverse human health or 

environmental effects of their programs, 

policies, and activities on minority 

populations and low-income 

populations in the U.S. 

The CAA requires that the EPA 

designate as nonattainment ‘‘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.’’ By 

designating as nonattainment all areas 

where available information indicates a 

violation of the ozone NAAQS or a 

contribution to a nearby violation, this 

action protects all those residing, 

working, attending school, or otherwise 

present in those areas regardless of 

minority or economic status. 

The EPA has determined that this 

final rule will not have 

disproportionately high and adverse 

human health or environmental effects 

on minority or low-income populations 

because it increases the level of 

environmental protection for all affected 

populations without having any 

disproportionately high and adverse 

human health or environmental effects 

on any population, including any 

minority or low-income population. 

K. Congressional Review Act 

The Congressional Review Act, 5 

U.S.C. 801 et seq., as added by the Small 

Business Regulatory Enforcement 

Fairness Act of 1996, generally provides 

that before a rule may take effect, the 

agency promulgating the rule must 

submit a rule report, which includes a 

copy of the rule, to each House of the 

Congress and to the Comptroller General 

of the U.S. The EPA will submit a report 

containing this rule and other required 

information to the U.S. Senate, the U.S. 

House of Representatives, and the 

Comptroller General of the U.S. prior to 

publication of the rule in the Federal 

Register. A major rule cannot take effect 

until 60 days after it is published in the 

Federal Register. This action is not a 

‘‘major rule’’ as defined by 5 U.S.C. 

804(2). This rule will be effective July 

20, 2012. 

L. Judicial Review 

Section 307(b)(1) of the CAA indicates 

which Federal Courts of Appeal have 

venue for petitions of 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: (i) When the agency action 

consists of ‘‘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 designating areas for the 

2008 ozone NAAQS is ‘‘nationally 

applicable’’ within the meaning of 

section 307(b)(1). This rule establishes 

designations for areas across the U.S. for 

the 2008 ozone NAAQS. At the core of 

this rulemaking is the EPA’s 

interpretation of the definition of 

nonattainment under section 107(d)(1) 

of the 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 

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 

mstockstill on DSK4VPTVN1PROD with RULES2

Federal Register / Vol. 77, No. 98 / Monday, May 21, 2012 / Rules and Regulations 30095 

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, 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 D.C. 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.

The area of the county north and east of the 

boundary defined by a line starting at the 

point defined by the intersection of the 

southwest corner Section 30 Range (R) 

115 West Township (T) 27N and the northwest corner of Section 31 R 115 West 

T27N of Sublette County at Sublette County’s border with Lincoln County. From this 

point the boundary moves to the west 500 

feet to Aspen Creek. The boundary follows 

the centerline of Aspen Creek downstream 

to the confluence of Aspen Creek and 

Fontenelle Creek (in R116W T26N, Section 

1). From this point the boundary moves 

generally to the south along the centerline 

of Fontenelle Creek to the confluence of 

Fontenelle Creek and Roney Creek (in 

R115W T24N Section 6). From the confluence, the boundary moves generally to 

the east along the centerline of Fontenelle 

Creek and into the Fontenelle Reservoir (in 

R112W T24N Section 6). The boundary 

moves east southeast along the centerline 

of the Fontenelle Reservoir and then toward the south along the centerline of the 

Green River to where the Green River in 

R111W T24N Section 31 crosses into 

Sweetwater County. 

Sublette County 

Sweetwater County (part) 

The area of the county west and north of the 

boundary which begins at the midpoint of 

the Green River, where the Green River 

enters Sweetwater County from Lincoln 

County in R111W T24N Section 31. From 

this point, the boundary follows the center 

of the channel of the Green River generally 

to the south and east to the confluence of 

the Green River and the Big Sandy River 

(in R109W T22N Section 28). From this 

point, the boundary moves generally north 

and east along the centerline of the Big 

Sandy River to the confluence of the Big 

Sandy River with Little Sandy Creek (in 

R106W T25N Section 33). The boundary 

continues generally toward the northeast 

along the centerline of Little Sandy Creek 

to the confluence of Little Sandy Creek and 

Pacific Creek (in R106W T25N Section 24). 

From this point, the boundary moves generally to the east and north along the centerline of Pacific Creek to the confluence of 

Pacific Creek and Whitehorse Creek (in 

R103W T26N Section 10). From this point 

the boundary follows the centerline of 

Whitehorse Creek generally to the northeast until it reaches the eastern boundary 

of Section 1 R103W T26N. From the point 

where Whitehorse Creek crosses the eastern section line of Section 1 R103W T26N, 

the boundary moves straight north along 

the section line to the southeast corner of 

Section 36 R103W T27N in Sublette County where the boundary ends.

Classifications Approach, Attainment 

Deadlines and Revocation of the 1997 

Ozone Standards for Transportation 

Conformity Purposes 

AGENCY: Environmental Protection 

Agency (EPA). 

ACTION: Final rule. 

SUMMARY: In this final rule, the EPA is 

establishing the air quality thresholds 

that define the classifications assigned 

to all nonattainment areas for the 2008 

ozone national ambient air quality 

standards (NAAQS) (the ‘‘2008 ozone 

NAAQS’’) which were promulgated on 

March 12, 2008. The EPA is also 

granting reclassification for selected 

nonattainment areas that voluntarily 

reclassified under the 1997 ozone 

NAAQS. This rule also establishes 

December 31 of each relevant calendar 

year as the attainment date for all 

nonattainment area classification 

categories. Finally, this rule provides for 

the revocation of the 1997 ozone 

NAAQS for transportation conformity 

purposes to occur 1 year after the 

effective date of designations for the 

2008 ozone NAAQS. 

DATES: This rule is effective on July 20, 

2012. 

ADDRESSES: The EPA has established a
