Air Quality Designations for the 2010 

Sulfur Dioxide (SO2) Primary National 

Ambient Air Quality Standard—Round 

3 

AGENCY: Environmental Protection 

Agency (EPA). 

ACTION: Final rule. 

SUMMARY: This final rule establishes the 

initial air quality designations for 

certain areas in the United States (U.S.) 

for the 2010 sulfur dioxide (SO2) 

primary National Ambient Air Quality 

Standard (NAAQS). The Environmental 

Protection Agency (EPA) is designating 

the areas as either Nonattainment, 

Attainment/Unclassifiable, or 

Unclassifiable. The designations are 

based on application of the EPA’s 

nationwide analytical approach and 

technical analysis, including evaluation 

of monitoring data and air quality 

modeling, to determine the appropriate 

designation based on the weight of 

evidence for each area. The Clean Air 

Act (CAA or Act) directs areas 

designated Nonattainment by this rule 

to undertake certain planning and 

pollution control activities to attain the 

SO2 NAAQS as expeditiously as 

practicable. This is the third of four 

expected sets of actions to designate 

areas of the U.S. for the 2010 SO2

NAAQS. 

DATES: The final rule is effective on 

April 9, 2018.

II. What is the purpose of this action? 

The purpose of this final action is to 

announce and promulgate initial air 

quality designations for certain areas in 

the U.S. for the 2010 SO2 NAAQS, in 

accordance with the requirements of the 

CAA. The EPA is designating areas as 

either Nonattainment, Attainment/ 

Unclassifiable, or Unclassifiable, based 

on the definitions described in Section 

IV in this preamble, and based on 

evaluating any available information, 

including (but not limited to) 

appropriate modeling analyses and/or 

monitoring data. 

This is the third round of designations 

for the 2010 SO2 NAAQS. As discussed 

in Section IV of this document, the EPA 

is designating SO2 areas in multiple 

rounds. The EPA completed the first 

round of SO2 designations in an action 

signed on July 25, 2013 (78 FR 47191; 

August 5, 2013). In that action, the EPA 

designated 29 areas in 16 states as 

Nonattainment, based on air quality 

monitoring data. In the second round of 

SO2 designations, in actions published 

on July 12, 2016 (81 FR 45039), and 

December 13, 2016 (81 FR 89870), the 

EPA designated 65 additional areas in 

24 states: 7 Nonattainment areas, 41 

Unclassifiable/Attainment areas and 17 

Unclassifiable areas. In this third round, 

6 areas are being designated 

Nonattainment; 23 areas are being 

designated Unclassifiable; and the rest 

of the areas covered by this round in all 

states, territories, and tribal lands are 

being designated Attainment/ 

Unclassifiable. In a future fourth round, 

the EPA expects to designate all 

remaining undesignated areas 

(approximately 50 areas) where states 

have installed and begun timely 

operation of a new SO2 monitoring 

network. 

The list of areas being designated in 

the affected states and the boundaries of 

each area appear in the tables for each 

state within the regulatory text at the 

end of this document. For areas in this 

action that meet our definition of 

‘‘Attainment/Unclassifiable,’’ the EPA 

notes this inversion, from previous 

rounds, of the order of the words 

‘‘Attainment’’ and ‘‘Unclassifiable’’ in 

the amended term ‘‘Attainment/ 

Unclassifiable area’’ has no consequence 

itself, and that there are no regulatory 

consequences of this change in, or 

clarified interpretation of, terminology 

to the areas in which the terms 

‘‘Attainment/Unclassifiable’’ or 

‘‘Unclassifiable’’ are applied. For 

consistency, we are also inverting the 

order of ‘‘Attainment’’ and 

‘‘Unclassifiable’’ for areas previously 

designated in Round 2 (81 FR 45039 and 

81 FR 89870). This re-ordering of the 

terms has no regulatory consequence 

and does not revisit the determinations 

made in Round 2 for these areas. The 

EPA believes this change is consistent 

with Congress’s definition of 

‘‘Attainment area’’ in CAA section 

107(d)(1)(A)(ii), and will improve public 

understanding and make clearer what 

regulations apply to areas designated in 

this way, which states have commented 

they believe is important for the 

economic development of such areas. 

These designations are based on the 

EPA’s nationwide analytical approach 

and technical assessment of and 

conclusions regarding the weight of 

evidence for each area, including but 

not limited to available air quality 

monitoring data or air quality modeling. 

With respect to air quality monitoring 

data, the EPA considered data from at 

least the most recent three calendar 

years 2014–2016 as available. In the 

modeling runs conducted by states or 

third parties, the impacts of the actual 

emissions for recent 3-year periods (e.g., 

2012–2014, 2013–2015, 2014–2016) 

were considered. In some cases, the 

modeling evaluated current allowable

1A total of 29 areas throughout the U.S. were 

designated in this action published on August 5, 

2013 (78 FR 47191). The EPA designated all 29 

areas Nonattainment based on violating monitored 

SO2 concentrations from Federal Reference Method 

and Federal Equivalent Method monitors that are 

sited and operated in accordance with 40 CFR parts 

50 and 58, and did not at that time designate any 

other areas. 

2A total of 65 areas throughout the U.S. were 

designated in these actions published on July 12, 

2016 (81 FR 45039), and December 13, 2016 (81 FR 

89870). Of these 65 areas, seven were designated 

Nonattainment.

emissions limits in lieu of or as a 

supplement to modeling of actual 

emissions. As described in Section VI 

and in limited circumstances, the EPA 

may consider early certified 2015–2017 

monitoring data or other documentation 

that demonstrates Attainment. This 

information would need to be submitted 

to the EPA by February 28, 2018. For the 

areas being designated Nonattainment, 

the CAA directs states to develop and 

submit to the EPA State Implementation 

Plans (SIPs) within 18 months of the 

effective date of this final rule, that meet 

the requirements of sections 172(c) and 

191–192 of the CAA and provide for 

Attainment of the NAAQS as 

expeditiously as practicable, but not 

later than 5 years from the effective date 

of this final rule. 

In 2010, the EPA issued a notice of 

final rulemaking that revised the 

primary SO2 NAAQS (75 FR 35520; June 

22, 2010) after review of the existing 

primary SO2 standards promulgated on 

April 30, 1971 (36 FR 8187). The EPA 

established the revised primary SO2

NAAQS at 75 parts per billion (ppb) 

which is attained when the 3-year 

average of the annual 99th percentile of 

1-hour daily maximum concentrations 

does not exceed 75 ppb. 

The process for designating areas 

following promulgation of a new or 

revised NAAQS is contained in the CAA 

section 107(d) (42 U.S.C. 7407(d)). After 

promulgation of a new or revised 

NAAQS, each governor or tribal leader 

has an opportunity to recommend air 

quality designations, including the 

appropriate boundaries for 

Nonattainment areas, to the EPA. The 

EPA considers these recommendations 

as part of its duty to promulgate the 

formal area designations and boundaries 

for the new or revised NAAQS. By no 

later than 120 days prior to 

promulgating designations, the EPA is 

required to notify states, territories, and 

tribes, as appropriate, of any intended 

modifications to an area designation or 

boundary recommendation that the EPA 

deems necessary. 

After invoking a 1-year extension of 

the deadlines to designate areas, as 

provided for in section 107 of the Act, 

the EPA completed an initial round of 

SO2 designations for certain areas of the 

country on July 25, 2013 (referred to as 

‘‘Round 1’’).1 Following the initial 

designations, three lawsuits were filed 

against the EPA in different U.S. District 

Courts, alleging the agency had failed to 

perform a nondiscretionary duty under 

the CAA by not designating all portions 

of the country by the June 2, 2013, 

deadline. In one of those cases, the U.S. 

District Court for the Northern District 

of California on March 2, 2015, entered 

an enforceable order for the EPA to 

complete the area designations by three 

specific deadlines according to the 

court-ordered schedule. 

To meet the first court-ordered 

deadline, additional areas were 

designated on June 30, 2016, and 

November 29, 2016 (collectively 

referred to as ‘‘Round 2’’).2 Pursuant to 

the court-ordered schedule,3 the EPA 

must complete SO2 designations for the 

remaining areas of the country by two 

specific deadlines: December 31, 2017, 

and December 31, 2020. This current 

third round of designations addresses 

all remaining undesignated areas except 

those where a state has installed and 

begun timely operating a new SO2

monitoring network meeting EPA 

specifications referenced in EPA’s SO2

Data Requirements Rule.4

On or about August 22, 2017, 

consistent with section 107(d)(1)(b)(ii) 

of the CAA, the EPA notified affected 

states, territories, and tribes of its 

intended designation of certain specific 

areas as either Nonattainment, 

Attainment/Unclassifiable, or 

Unclassifiable for the SO2 NAAQS. 

These states then had the opportunity to 

demonstrate why they believed an 

intended modification of their updated 

recommendations by the EPA may be 

inappropriate. Although not required 

under the CAA, as the EPA had done for 

the first and second rounds of SO2

designations, the EPA also chose to 

provide an opportunity for members of 

the public to comment on the EPA’s 

August 2017 letters. The EPA published 

a notice of availability and public 

comment period for the intended 

designations on September 5, 2017 (82 

FR 41903). The public comment period 

closed on October 5, 2017. The 

recommendations, the EPA’s August 

2017 letters, and the subsequent state 

and public comment letters, are in the 

docket for this third round of SO2

designations at Docket ID No. EPA–HQ– 

OAR–2017–0003 and are available on 

the SO2 designations website. 

III. What is the 2010 SO2 NAAQS and 

what are the health concerns that it 

addresses? 

The EPA revised the primary SO2

NAAQS in a final rule published in the 

Federal Register on June 22, 2010 (75 

FR 35520), which became effective on 

August 23, 2010. Based on review of the 

air quality criteria for oxides of sulfur 

and the primary NAAQS for oxides of 

sulfur as measured by SO2, the EPA 

revised the primary SO2 NAAQS to 

provide requisite protection of public 

health with an adequate margin of 

safety. Specifically, the EPA established 

a new 1-hour SO2 standard at a level of 

75 ppb, which is met at an ambient air 

quality monitoring site when the 3-year 

average of the annual 99th percentile of 

1-hour daily maximum concentrations 

is less than or equal to 75 ppb, as 

determined in accordance with 

Appendix T of 40 CFR part 50. 40 CFR 

50.17(a) and (b). The EPA also 

established provisions to revoke both 

the existing 24-hour and annual primary 

SO2 standards, subject to certain 

conditions. 40 CFR 50.4(e). 

Current scientific evidence links 

short-term exposures to SO2, ranging 

from 5 minutes to 24 hours, with an 

array of adverse respiratory effects 

including bronchoconstriction and 

increased asthma symptoms. These 

effects are particularly important for 

asthmatics at elevated ventilation rates 

(e.g., while exercising or playing). 

Studies also show a connection between 

short-term exposure and increased visits 

to emergency departments and hospital 

admissions for respiratory illnesses, 

particularly in at-risk populations 

including children, the elderly and 

asthmatics. 

IV. What are the CAA requirements for 

air quality designations and what 

action has the EPA taken to meet these 

requirements? 

After the EPA promulgates a new or 

revised NAAQS, the EPA is required to 

designate all areas of the country as 

either ‘‘Nonattainment,’’ ‘‘Attainment,’’ 

or ‘‘Unclassifiable,’’ for that NAAQS 

pursuant to section 107(d)(1) of the 

CAA. As part of these Round 3 

designations, the EPA is implementing 

its interpretation of statutory terms 

under CAA section 107(d) nationwide 

and is basing these designations on the 

EPA’s nationwide analytical approach 

and technical analysis, including 

evaluation of monitoring data and air 

quality modeling, applied to the 

available evidence for each area.

5This view was confirmed in Catawba County v. 

EPA, 571 F.3d 20 (D.C. Cir. 2009). 

6Tribes are invited to submit recommendations 

following promulgation of a new or revised 

NAAQS, but are not required to do so. 

7See, ‘‘Area Designations for the 2010 Revised 

Primary Sulfur Dioxide National Ambient Air 

Quality Standards,’’ memorandum to Regional Air 

Division Directors, Regions I–X, from Stephen D. 

Page, dated March 24, 2011. 

Regarding statutory definitions and 

the EPA’s interpretations of such, 

section 107(d)(1)(A)(i) of the CAA 

defines a Nonattainment area as an area 

that does not meet the NAAQS or that 

contributes to a nearby area that does 

not meet the NAAQS. An Attainment 

area is defined by the CAA as any area 

that meets the NAAQS and does not 

contribute to a nearby area that does not 

meet the NAAQS. Unclassifiable areas 

are defined by the CAA as those that 

cannot be classified on the basis of 

available information as meeting or not 

meeting the NAAQS. 

For the purpose of this action for the 

2010 SO2 NAAQS, the EPA has 

interpreted and applied the statutory 

definitions as follows. The EPA defines 

a Nonattainment area as an area that the 

EPA has determined violates the 2010 

SO2 NAAQS or contributes to a 

violation in a nearby area, based on the 

most recent 3 years of air quality 

monitoring data, appropriate dispersion 

modeling analysis, and any other 

relevant information. 

In this action, an Attainment/ 

Unclassifiable area is defined by the 

EPA as an area that either: (1) Was not 

required to be characterized under 40 

CFR 51.1203(c) or (d) for which 

available information does not indicate 

that the area violates the NAAQS or 

contributes to ambient air quality in a 

nearby area that does not meet the 

NAAQS; or (2) was required to be 

characterized under 40 CFR 51.1203(c) 

or (d) for which the EPA has determined 

the available information indicates the 

area meets the NAAQS and does not 

indicate the area contributes to ambient 

air quality in a nearby area that does not 

meet the NAAQS. 

In this action, an Unclassifiable area 

is defined by the EPA as an area for 

which the available information does 

not allow the EPA to determine whether 

the area meets the definition of a 

Nonattainment area or the definition of 

an Attainment/Unclassifiable area. 

This nationwide analytical approach 

also includes but is not limited to: (1) 

EPA’s interpretations of other terms in 

the context of Round 3 of the 2010 SO2

NAAQS; (2) the appropriate basis for 

characterizing the air quality of an area; 

(3) the five-factor analysis to determine 

the boundaries for each air quality area 

under the NAAQS; and (4) the 

methodology for appropriately 

characterizing SO2 air quality through 

monitoring or modeling. 

The EPA notes that CAA section 

107(d) provides the agency with 

discretion to determine how best to 

interpret the terms in the definition of 

a Nonattainment area (e.g., ‘‘contributes 

to’’ and ‘‘nearby’’) 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’s 

position is 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.5

Similarly, the EPA’s position is that 

the statute permits the EPA to evaluate 

the appropriate application of the term 

‘‘area’’ to include geographic areas 

based upon full or partial county 

boundaries, as may be appropriate for a 

particular NAAQS. For example, CAA 

section 107(d)(1)(B)(ii) explicitly 

provides that the EPA can make 

modifications to designation 

recommendations for an area ‘‘or 

portions thereof,’’ and under CAA 

section 107(d)(1)(B)(iv) a designation 

remains in effect for an area ‘‘or portion 

thereof’’ until the EPA redesignates it. 

By no later than 1 year after the 

promulgation of a new or revised 

NAAQS, CAA section 107(d)(1)(A) 

provides that each state governor is 

required to recommend air quality 

designations, including the appropriate 

boundaries for areas, to the EPA.6 The 

EPA reviews those 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 

Administrator. If the EPA is considering 

modifications to a recommendation, we 

are required by CAA section 

107(d)(1)(B)(ii) to notify the state of any 

such intended modifications not less 

than 120 days prior to our promulgation 

of the final designation. These 

notifications are commonly known as 

the ‘‘120-day letters.’’ During this 

period, if the state or territory does not 

agree with the EPA’s proposed 

modification, it has an opportunity to 

respond to the EPA and to demonstrate 

why it believes the modification 

proposed by the EPA is inappropriate. If 

a state or territory 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, pursuant to CAA 

section 107(d)(1)(B)(ii). While CAA 

section 107(d) specifically addresses the 

designations process between the EPA 

and states and territories, the EPA 

followed the same process to the extent 

practicable for tribes that submitted 

designation recommendations. 

V. What guidance did the EPA issue 

and how did the EPA apply the 

statutory requirements and applicable 

guidance to determine area 

designations and boundaries? 

In the notice of proposed rulemaking 

for the revised SO2 NAAQS (74 FR 

64810; December 8, 2009), the EPA 

issued proposed guidance on our 

approach to implementing the standard, 

including our approach to initial area 

designations. The EPA solicited 

comment on that guidance and, in the 

notice of final rulemaking (75 FR 35520; 

June 22, 2010), provided further 

guidance concerning implementation of 

the standard and how to identify 

Nonattainment areas and boundaries for 

the SO2 NAAQS. Subsequently, on 

March 24, 2011, the EPA provided 

additional designations guidance to 

assist states with making their 

recommendations for area designations 

and boundaries.7 That guidance 

recommended, among other things, that 

monitoring data from the most recent 3 

consecutive years be used to identify a 

violation of the SO2 NAAQS. This is 

appropriate because the form of the SO2

NAAQS is calculated as a 3-year average 

of the 99th percentile of the yearly 

distribution of 1-hour daily maximum 

SO2 concentrations (specifically the 

most recent 3 consecutive years). The 

EPA based the first round of final SO2

designations in 2013 solely on violating 

monitored SO2 concentrations for the 

years 2010–2012 from Federal Reference 

Method and Federal Equivalent Method 

monitors that are sited and operated in 

accordance with 40 CFR parts 50 and 

58, and did not at that time designate 

any other areas. 

In the March 24, 2011, guidance, the 

EPA stated that the perimeter of a 

county containing a violation would be 

the initial presumptive boundary for 

Nonattainment areas, but also stated 

that the state, tribe and/or the EPA 

could conduct additional area-specific 

analyses that could justify establishing 

either a larger or smaller area. The EPA 

indicated that the following factors 

should be considered in an analysis of 

whether to exclude portions of a county

documents first made available to states and other 

interested parties in 2013 and updated in 2016. See

Directors from Richard A. Wayland, dated March 8, 

2017. This memo is available at https://

www3.epa.gov/ttn/scram/guidance/clarification/ 

SO2_DRR_Designation_Modeling_Clarification_

Memo-03082017.pdf. 

11The single final TSD for this action consists of 

a few sections with information that applies to all 

affected areas or to certain groups of areas with 

and whether to include additional 

nearby areas outside the county as part 

of the designated Nonattainment area: 

(1) Air quality data; (2) emissionsrelated data; (3) meteorology; (4) 

geography/topography; and (5) 

jurisdictional boundaries, as well as 

other available data. States and tribes 

may identify and evaluate other relevant 

factors or circumstances specific to a 

particular area. 

Following entry of the March 2, 2015, 

court order setting forth the schedule for 

the EPA to complete SO2 designations, 

the EPA issued updated designations 

guidance.8 This guidance superseded 

the March 24, 2011, designation 

guidance for the 2010 SO2 NAAQS, and 

identified factors that the EPA intended 

to evaluate in determining whether 

areas are in violation of the 2010 SO2

NAAQS or contribute to air quality in 

nearby areas that are in violation of the 

2010 SO2 NAAQS. The guidance also 

contained the factors the EPA intended 

to evaluate in determining the 

boundaries for all remaining areas in the 

country, consistent with the court’s 

order and schedule. These factors 

include: (1) Air quality characterization 

via ambient monitoring or dispersion 

modeling results; (2) emissions-related 

data; (3) meteorology; (4) geography and 

topography; and (5) jurisdictional 

boundaries.9

On March 8, 2017, the EPA issued a 

memo to clarify what version of the 

AERMOD modeling system is the most 

appropriate for consideration by the 

agency in the SO2 designations 

process.10

VI. What air quality information has 

the EPA used for these designations? 

For designations for the SO2 NAAQS, 

air agencies have the flexibility to 

characterize air quality using either 

appropriately sited ambient air quality 

monitors or modeling of actual or 

current allowable source emissions. 

These designations are based on the 

EPA’s application of the nationwide 

analytical approach to, and technical 

assessment of, the weight of evidence 

for each area, including but not limited 

to available air quality monitoring data 

and air quality modeling results. The 1- 

hour primary SO2 standard is violated at 

an ambient air quality monitoring site 

(or in the case of dispersion modeling, 

at an ambient air quality receptor 

location) when the 3-year average of the 

annual 99th percentile of the daily 

maximum 1-hour average 

concentrations exceeds 75 ppb, as 

determined in accordance with 

Appendix T of 40 CFR part 50. With 

respect to air quality monitoring data, 

the EPA has considered data from at 

least the most recent 3 calendar years, 

i.e., 2014–2016, as available. In most of 

the modeling runs available for EPA’s 

review, the impacts of the actual 

emissions for one or more of the recent 

3-year periods (e.g., 2012–2014, 2013– 

2015, 2014–2016) were considered, and 

in some cases the modeling was of 

currently effective limits on allowable 

emissions in lieu of or as a supplement 

to modeling of actual emissions. 

The deadline for Round 3 

designations and the practical 

difficulties of obtaining source 

emissions data for modeling, and 

complete, quality-assured, certified SO2

monitoring data for the entirety of 

calendar year 2017 in December 2017, 

make the EPA’s use of final 2017 

emissions and monitoring data for this 

action generally impracticable. Under 

normal circumstances, the full year of 

such data would not be available to 

support regulatory determinations until 

after the end of the calendar year, and 

under the applicable regulations, the 

deadline for states to certify monitoring 

data is May 1, 2018. However, because 

these designations are being 

promulgated at the end of calendar year 

2017, and because states can obtain 

source emissions information and make 

complete, quality-assured, certified 

2017 data available for some areas 

quickly in 2018, in order to address the 

impracticability problem, the EPA is 

providing a process by which statecertified 2017 monitoring or emissions 

data that become available early in 2018 

could be used in the designation 

process. We have provided that the final 

SO2 designation decisions announced in 

this action will be effective on the date 

90 days following the date of 

publication of this action in the Federal 

Register. If any state submits complete, 

quality-assured, certified 2017 data or 

related information about 2017 air 

quality to the EPA by February 28, 2018, 

supporting a change of the designation 

status for any area within that state, and 

the EPA agrees that a change of 

designation status is appropriate, then 

we will withdraw the designation 

announced in this action for such area 

and issue another designation that 

reflects the inclusion and analysis of 

such information. We emphasize that 

we will conduct this process only for 

those states that submit the information 

by the deadline of February 28, 2018, 

and in those instances where we can 

complete our analysis of the information 

and effect the change of designation 

status before the original effective date 

established by this final action. 

If these submissions cause an area to 

change from Nonattainment to 

Attainment or Unclassifiable, the EPA 

will change the designation for the area 

following the process described in the 

preceding paragraph. If inclusion of 

2017 data or related information about 

2017 air quality indicates 

Nonattainment in an area that was 

designated Attainment or 

Unclassifiable, we will evaluate the 

reasons for the violation in the area and 

determine the appropriate course of 

action, which could include additional 

future action to change the designation 

for the area to Nonattainment. 

VII. How do the Round 3 designations 

affect Indian country? 

For areas of Indian country, there are 

no violating monitors. The Navajo 

Nation submitted modeling analyses for 

the areas around two SO2 emission 

sources located in the Navajo Nation, 

the Navajo Generating Station and the 

Four Corners Power Plant, neither of 

which indicated a violation of the 

NAAQS. The Navajo Nation, the lands 

of the Hopi Tribe, and the Southern Ute 

Indian Reservation are being designated 

as separate areas. All other parts of 

Indian country are being designated as 

Attainment/Unclassifiable or 

Unclassifiable along with the 

surrounding state area. No areas of 

Indian country are being designated as 

Nonattainment in this round. 

VIII. 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 final action are provided in a final 

technical support document (TSD) 11

some common features, and many sections that are 

specific to individual states, territories, or tribal 

areas. For convenience, the term ‘‘TSD’’ is also used 

generically to refer to these state/territory/tribespecific sections. For informational purposes, these 

individual state/territory/tribe-specific sections/

included in the docket. The final TSD, 

intended designations TSD, modeling 

files, technical assistance documents, 

applicable EPA guidance memoranda, 

public comments, and copies of 

correspondence regarding this process 

between the EPA and the states, 

territories, tribes, and other parties, are 

available for review at the public docket 

for these SO2 designations at https://

www.regulations.gov under Docket ID 

No. EPA–HQ–OAR–2017–0003, at the 

EPA Docket Center listed above in the 

ADDRESSES section of this document and 

on the agency’s SO2 Designations 

website at https://www.epa.gov/sulfurdioxide-designations. Area-specific 

questions can be addressed to the EPA 

Regional offices (see contact information 

provided at the beginning of this 

document). 

IX. 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 action addresses 

designation determinations for certain 

areas for the 2010 SO2 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. 

X. 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 nondiscretionary 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, as specified in Executive 

Order 13175. This action concerns the 

designation of certain areas in the U.S. 

for the 2010 SO2 NAAQS. The CAA 

provides for states, territories, and 

eligible tribes to develop plans to 

regulate emissions of air pollutants 

within their areas, as necessary, based 

on the designations. The Tribal 

Authority Rule (TAR) provides tribes 

the opportunity to apply for eligibility 

to develop and implement CAA 

programs, such as programs to attain 

and maintain the SO2 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. It would not 

create any additional requirements 

beyond those of the SO2 NAAQS. This 

rule establishes the designations for 

certain areas of the country for the SO2

NAAQS, but no areas of Indian country 

are being designated as Nonattainment 

by this action. Furthermore, this rule 

does not affect the relationship or 

distribution of power and 

responsibilities between the federal 

government and Indian tribes. The CAA 

and the TAR establish the relationship 

of the federal government and tribes in 

developing plans to attain the NAAQS, 

and this rule does nothing to modify 

that relationship. Thus, Executive Order 

13175 does not apply. 

Although Executive Order 13175 does 

not apply to this rule, after the EPA 

promulgated the 2010 primary SO2

NAAQS, the EPA communicated with 

tribal leaders and environmental staff 

regarding the designations process. In 

2011, the EPA also sent individualized 

letters to all federally recognized tribes 

to explain the designation process for 

the 2010 primary SO2 NAAQS, to 

provide the EPA designations guidance, 

and to offer consultation with the EPA. 

The EPA provided further information 

to tribes through presentations at the 

National Tribal Forum and through 

participation in National Tribal Air 

Association conference calls. The EPA 

also sent individualized letters to all 

federally recognized tribes that 

submitted recommendations to the EPA 

about the EPA’s intended Round 1 

designations for the SO2 standard and 

offered tribal leaders the opportunity for 

consultation.12 These communications 

provided opportunities for tribes to 

voice concerns to the EPA about the 

general designations process for the 

2010 SO2 NAAQS, as well as concerns 

specific to a tribe, and informed the EPA 

about key tribal concerns regarding 

designations as the designations process 

was under development and through its 

implementation up to that point. For the 

second round of SO2 designations, the 

EPA sent additional letters to tribes that 

could potentially be affected and offered 


sradovich on DSK3GMQ082PROD with RULES2
1104 Federal Register / Vol. 83, No. 6 / Tuesday, January 9, 2018 / Rules and Regulations 

additional opportunities for 

participation in the designations 

process. For this third round of SO2

designations, the EPA has sent similar 

letters to affected 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, lowincome 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 IX 

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 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 final action to designate certain 

areas for the 2010 SO2 NAAQS is 

‘‘nationally applicable’’ within the 

meaning of section 307(b)(1). The final 

action establishes designations for areas 

across the U.S. for the 2010 SO2

NAAQS. At the core of this action is the 

EPA’s nationwide analytical approach 

and technical analysis, including 

evaluation of monitoring data and air 

quality modeling, applied to the 

available evidence for each area, 

including the EPA’s interpretation of 

statutory terms in the CAA such as the 

definitions of Nonattainment, 

Attainment, and Unclassifiable under 

section 107(d)(1) of the CAA, and its 

application of that interpretation to 

areas across the country. Accordingly, 

the Administrator has determined that 

the final action is nationally applicable 

and is hereby publishing that finding in 

the Federal Register. 

For the same reasons discussed above 

that make the final rule nationally 

applicable, the Administrator also has 

determined 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 U.S.C.C.A.N. 

1402–03. Here, the scope and effect of 

the action will extend to numerous 

judicial circuits since the designations 

will apply to areas across the country. 

In these circumstances, section 307(b)(1) 

and its legislative history calls for the 

Administrator to find the action to be of 

‘‘nationwide scope or effect’’ and for 

venue to be in the D.C. Circuit. 

Therefore, the Administrator has 

determined that the final action is based 

on a determination by the Administrator 

of nationwide scope or effect, and is 

hereby publishing that finding in the 

Federal Register.
