Air Quality Designations for the 2010 Sulfur Dioxide (SO2) 
Primary National Ambient Air Quality Standard--Round 2

AGENCY: Environmental Protection Agency (EPA).

ACTION: Final rule.

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

SUMMARY: This rule establishes the initial air quality designations for 
certain areas in the United States (U.S.) for the 2010 primary sulfur 
dioxide (SO2) National Ambient Air Quality Standard (NAAQS). 
The Environmental Protection Agency (EPA) is designating the areas as 
either nonattainment, unclassifiable/attainment, or unclassifiable, 
based on whether the areas do not meet the NAAQS or contribute to a 
nearby area that does not meet the NAAQS; meet the NAAQS; or cannot be 
classified on the basis of available information as meeting or not 
meeting the NAAQS, respectively. The designations are based on the 
weight of evidence for each area, including available air quality 
monitoring data and air quality modeling. The Clean Air Act (CAA) 
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 
second round of area designations for the 2010 SO2 NAAQS.

DATES: The effective date of this rule is September 12, 2016.

ADDRESSES: The EPA has established a docket for this action under 
Docket ID NO. EPA-HQ-OAR-2014-0464. All documents in the docket are

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 primary SO2 NAAQS, in accordance with the requirements 
of the CAA. The EPA is designating areas as either nonattainment, 
unclassifiable/attainment, or unclassifiable, based on whether the 
areas do not meet the NAAQS or contribute to a nearby area that does 
not meet the NAAQS; meet the NAAQS; or cannot be classified on the 
basis of available information as meeting or not meeting the NAAQS, 
respectively. This is the second 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 by the Administrator 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 this second round of SO2 designations, the EPA is 
designating 61 additional areas in 24 states: 4 nonattainment areas, 41 
unclassifiable/attainment areas and 16 unclassifiable

[[Page 45041]]

areas. 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. These designations are 
based on the EPA's 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 2013-2015, as available, 
including an evaluation of exceptional event claims.\1\ In most of the 
modeling runs conducted by states or third parties, the impacts of the 
actual emissions for the 3-year periods 2012-2014 or 2013-2015 were 
considered, and in some cases modeling evaluated recent or not-yet-
effective allowable emissions limits in lieu of or as a supplement to 
modeling of actual emissions. For the areas being designated 
nonattainment, the CAA directs states to develop and submit to the EPA 
State Implementation Plans 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. We also note that under EPA's Data Requirements Rule 
in 40 CFR part 51, subpart BB (80 FR 51052; August 21, 2015), the EPA 
expects to receive additional air quality characterization for many of 
the sources located in areas subject to this round of designations, and 
the agency could consider such data that corresponds to those areas 
designated unclassifiable in this round in future actions that assess 
the areas' air quality status.
---------------------------------------------------------------------------

    \1\ Exceptional event claims influenced the EPA's designation 
for an area in Hawaii. The CAA and the EPA's implementing 
regulations allow for the exclusion of air quality monitoring data 
from use in regulatory determinations when there are exceedances 
and/or violations caused by events that satisfy the criteria within 
the Exceptional Events Rule codified at 40 CFR 50.1, 50.14 and 
51.930. The exclusion of event-influenced data from the data set 
that is used to calculate design values could result in regulatory 
relief from an initial area designation as nonattainment. The design 
value used to determine the unclassifiable/attainment area 
designation for Hawaii County, Hawaii reflects the EPA's concurrence 
on multiple exceptional events claims influencing monitored 
concentrations at monitors in Hawaii County, Hawaii.
---------------------------------------------------------------------------

III. What is the 2010 SO2 NAAQS and what are the health concerns that 
it addresses?

    The Administrator signed a final rule revising the primary 
SO2 NAAQS on June 2, 2010. The rule was published in the 
Federal Register on June 22, 2010 (75 FR 35520) and became effective on 
August 23, 2010. Based on the Administrator's 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 parts per billion 
(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)-(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.
    The EPA's NAAQS for SO2 is designed to protect against 
exposure to the entire group of sulfur oxides (SOX). 
SO2 is the component of greatest concern and is used as the 
indicator for the larger group of gaseous SOX. Other gaseous 
SOX (e.g., SO3) are found in the atmosphere at 
concentrations much lower than SO2.
    Emissions that lead to high concentrations of SO2 
generally also lead to the formation of other SOX. Control 
measures that reduce SO2 can generally be expected to reduce 
people's exposures to all gaseous SOX. This may also have 
the important co-benefit of reducing the formation of fine sulfate 
particles, which pose significant public health threats. SOX 
can react with other compounds in the atmosphere to form small 
particles. These particles penetrate deeply into sensitive parts of the 
lungs and can cause or worsen respiratory disease, such as emphysema 
and bronchitis, and can aggravate existing heart disease, leading to 
increased hospital admissions and premature death.\2\ The EPA's NAAQS 
for particulate matter are designed to provide protection against these 
health effects.
---------------------------------------------------------------------------

    \2\ See Fact Sheet titled, ``Revisions to the Primary National 
Ambient Air Quality Standard, Monitoring Network, and Data Reporting 
Requirements for Sulfur Dioxide'' at http://www3.epa.gov/airquality/sulfurdioxide/pdfs/20100602fs.pdf.
---------------------------------------------------------------------------

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,'' \3\ or ``unclassifiable,'' for that 
NAAQS 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.'' This provision also defines an attainment area as 
any area other than a nonattainment area that meets the NAAQS and an 
unclassifiable area as any area that cannot be classified on the basis 
of available information as meeting or not meeting the NAAQS.
---------------------------------------------------------------------------

    \3\ Consistent with designations for other pollutants, the EPA 
is using the designation category of ``unclassifiable/attainment'' 
for areas where appropriate air quality data demonstrate attainment 
(for SO2 this can be through monitoring and/or modeling) 
and for areas for which such data are not available but for which 
the EPA has reason to believe the areas are likely attainment and 
have not been determined to be contributing to nearby violations.
---------------------------------------------------------------------------

    The process for designating areas following promulgation of a new 
or revised NAAQS is contained in section 107(d) of the CAA. The CAA 
requires the EPA to complete the initial designations process within 2 
years of promulgating a new or revised standard. If the Administrator 
has insufficient information to make these designations by that 
deadline, the EPA has the authority to extend the deadline for 
completing designations by up to 1 year. On July 27, 2012, the EPA 
announced that it had insufficient information to complete the 
designations for the 1-hour SO2 standard within 2 years and 
extended the designations deadline to June 3, 2013 (77 FR 46295; August 
3, 2012).
    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

[[Page 45042]]

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.'' During this period, if the state does 
not agree with the EPA's 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 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, the EPA intends to follow the same process to the extent 
practicable for tribes that choose to make designation recommendations. 
If a tribe does not provide designation recommendations, the EPA will 
promulgate the designations that the Administrator deems appropriate.
    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.\4\
---------------------------------------------------------------------------

    \4\ This view was confirmed in Catawba County v. EPA, 571 F.3d 
20 (D.C. Cir. 2009).
---------------------------------------------------------------------------

    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.
    For the 2010 SO2 NAAQS, designation recommendations were 
due to the EPA by June 3, 2011. Designation recommendations and 
supporting documentation were submitted by most states and several 
tribes to the EPA by that date. After receiving these recommendations, 
and after reviewing and evaluating each recommendation, the EPA 
provided responses to the states and tribes regarding certain areas on 
February 7, 2013. The state and tribal letters, including the initial 
recommendations, the EPA's February 2013 responses to those letters, 
any modifications, and the subsequent state comment letters, are in the 
separate docket for that first round of SO2 designations, at 
Docket ID NO. EPA-HQ-OAR-2012-0233.
    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 February 2013 response letters. The EPA completed the first round 
of SO2 designations on July 25, 2013, designating 29 areas 
in 16 states as nonattainment (78 FR 47191; August 5, 2013). In the 
preamble to that action, the EPA stated that in separate future 
actions, it intended to address designations for all other areas for 
which the agency was not yet prepared to issue designations and that 
were consequently not addressed in that final rule. With input from a 
diverse group of stakeholders, EPA developed a comprehensive 
implementation strategy for the future SO2 designations 
actions that focuses resources on identifying and addressing unhealthy 
levels of SO2 in areas where people are most likely to be 
exposed to violations of the standard.
    Following the initial August 5, 2013, 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 an effort intended to resolve the litigation in one of 
those cases, the EPA and the plaintiffs, Sierra Club and the Natural 
Resources Defense Council, filed a proposed consent decree with the 
U.S. District Court for the Northern District of California. On March 
2, 2015, the court entered the consent decree and issued an enforceable 
order for the EPA to complete the area designations by three specific 
deadlines according to the court-ordered schedule.
    According to the court-ordered schedule, the EPA must complete this 
second round of SO2 designations by no later than July 2, 
2016 (16 months from the court's order). The court order specifies that 
in this round the EPA must designate two groups of areas: (1) Areas 
that have newly monitored violations of the 2010 SO2 NAAQS 
and (2) areas that contain any stationary sources that had not been 
announced as of March 2, 2015, for retirement and that, according to 
the EPA's Air Markets Database, emitted in 2012 either (i) more than 
16,000 tons of SO2, or (ii) more than 2,600 tons of 
SO2 with an annual average emission rate of at least 0.45 
pounds of SO2 per one million British thermal units (lbs 
SO2/mmBTU). Specifically, a stationary source with a coal-
fired electric generating unit that, as of January 1, 2010, had a 
capacity of over 5 megawatts and otherwise meets the emissions 
criteria, is excluded from the July 2, 2016, deadline if it had 
announced through a company public announcement, public utilities 
commission filing, consent decree, public legal settlement, final state 
or federal permit filing, or other similar means of communication, by 
March 2, 2015, that it will cease burning coal at that unit.
    The last two court-ordered deadlines for completing remaining 
designations are December 31, 2017 (Round 3), and December 31, 2020 
(Round 4). In Round 3, the EPA must designate any remaining 
undesignated areas, for which, by January 1, 2017, states have not 
installed and begun operating a new SO2 monitoring network 
meeting the EPA's specifications referenced in the then-anticipated 
SO2 Data Requirements Rule. By December 31, 2020, the EPA 
must designate all remaining areas. The EPA finalized the 
SO2 Data Requirements Rule (DRR) on August 10, 2015, 
codified at 40 CFR part 51, subpart BB (80 FR 51052; August 21, 2015). 
The rule establishes requirements for state and other air agencies to 
provide additional monitoring or modeling information on a timetable 
consistent with these designation deadlines. We expect this additional 
information to become available in time to help inform these subsequent 
designations.
    On March 20, 2015, the EPA sent letters to Governors notifying them 
of the March 2, 2015, court order and identifying any sources in their 
states meeting the criteria for the round of

[[Page 45043]]

designations to be completed by July 2, 2016. The EPA offered states 
the opportunity to submit updated recommendations and supporting 
information for the EPA to consider for the affected areas. The EPA 
also notified states that the agency had updated its March 24, 2011, 
SO2 designations guidance to support analysis of 
designations and boundaries for the next rounds of designations. All of 
the states with affected areas submitted updated designation 
recommendations. For areas of Indian county, there were no violating 
monitors and no sources meeting the criteria for the designations to be 
completed by July 2, 2016. However, the EPA also sent letters to Tribal 
Leaders where the EPA had identified a state source that met the 
criteria in the court order and that could potentially be impacting the 
tribal land. The EPA also offered tribes the opportunity to submit 
information or a recommendation for the potentially affected areas of 
tribal land. No tribes submitted information or recommendations for 
this round of designations.
    On or about February 16, 2016, the EPA notified 24 affected states 
of its intended designation of certain specific areas as either 
nonattainment, unclassifiable/attainment, 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, 
as the EPA had done for the first round of SO2 designations, 
the EPA also chose to provide an opportunity for members of the public 
to comment on the EPA's February 2016 response letters. The EPA 
published a notice of availability and public comment period for the 
intended designation on March 1, 2016 (81 FR 10563). The public comment 
period closed on March 31, 2016. The updated recommendations, the EPA's 
February 2016 responses to those letters, any modifications, and the 
subsequent state and public comment letters, are in the docket for this 
second round of SO2 designations at Docket ID NO. EPA-HQ-
OAR-2014-0464 and are available on the SO2 designations Web 
site.

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 its approach to implementing the standard, including its 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.\5\ That guidance 
recommended, among other things, that monitoring data from the most 
recent three 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 on 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.
---------------------------------------------------------------------------

    \5\ See, ``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.
---------------------------------------------------------------------------

    In the March 24, 2011, guidance, the EPA stated that the perimeter 
of a county containing a violating monitor 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 and whether 
to include additional nearby areas outside the county as part of the 
designated nonattainment area: (1) Air quality data; (2) emissions-
related 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, updated 
designations guidance was issued by the EPA through a March 20, 2015, 
memorandum from Stephen D. Page, Director, U.S. EPA, Office of Air 
Quality Planning and Standards, to Air Division Directors, U.S. EPA 
Regions 1-10. This memorandum supersedes the March 24, 2011, 
designation guidance for the 2010 SO2 NAAQS, and identifies 
factors that the EPA intends to evaluate in determining whether areas 
are in violation of the 2010 SO2 NAAQS. The guidance also 
contains the factors the EPA intends 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. This guidance was 
supplemented by two non-binding technical assistance documents intended 
to assist states and other interested parties in their efforts to 
characterize air quality through air dispersion modeling or ambient air 
quality monitoring for sources that emit SO2. Notably, the 
EPA's documents titled, ``SO2 NAAQS Designations Modeling 
Technical Assistance Document'' (Modeling TAD) and ``SO2 
NAAQS Designations Source-Oriented Monitoring Technical Assistance 
Document'' (Monitoring TAD), were first made available to states and 
other interested parties in spring of 2013. Both of these documents 
were most recently updated in February 2016 and are available at 
https://www.epa.gov/sulfur-dioxide-designations.

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 allowable 
source emissions. The EPA issued the non-binding draft Monitoring TAD 
and Modeling TAD recommending how air agencies should conduct such 
monitoring or modeling. For the SO2 designations contained 
in this action, the EPA considered available air quality monitoring 
data from at least calendar years 2013-2015, including an evaluation of 
exceptional events claims, and modeling submitted by state air agencies 
and other parties. In most of the modeling runs, the impacts of the 
actual emissions for the 3-year periods 2012-2014 or 2013-2015 were 
considered, and in some cases modeling evaluated recent or not-yet-
effective allowable emissions limits in lieu of or as a supplement to 
modeling of actual emissions. 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

[[Page 45044]]

average concentrations exceeds 75 ppb, as determined in accordance with 
appendix T of 40 CFR part 50. For this round of designations there were 
no areas designated nonattainment based on monitoring data showing 
violations of the NAAQS. To determine model-based violations, the EPA 
believes that dispersion modeling is an appropriate tool, as discussed 
in the Modeling TAD. The TAD provides recommendations on how an air 
agency might appropriately and sufficiently model ambient air in 
proximity to an SO2 emission source to establish air quality 
data for comparison to the 2010 primary SO2 NAAQS for the 
purposes of designations.

VII. How do the Round 2 designations affect Indian country?

    In Round 2 of the designations for the 2010 primary SO2 
NAAQS, the EPA is designating 61 state areas as either nonattainment, 
unclassifiable/attainment, or unclassifiable. For areas of Indian 
county, there were no violating monitors and no sources meeting the 
criteria for the designations to be completed by July 2, 2016. No areas 
of Indian country are being designated as nonattainment as part of this 
round. Any Indian country located in areas being designated as 
unclassifiable/attainment or unclassifiable are being designated along 
with the surrounding state area. All remaining state areas and areas of 
Indian country will be addressed in subsequent rounds of SO2 
designations.

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 action are provided in 
several technical support documents (TSDs), a response to comments 
document (RTC) and other information in the docket. The TSDs, RTC, 
applicable EPA's 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 agency's 
SO2 Designations Web site at https://www.epa.gov/sulfur-dioxide-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 final action addresses designation determinations for certain 
areas for the 2010 primary 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

    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 selected areas as required.

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

    This action is exempted from review from 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. Paperwork Reduction Act (PRA)

    This action does not impose an information collection burden under 
the PRA. This action responds to the requirement to promulgate air 
quality designations after promulgation of a new or revised NAAQS. This 
requirement is prescribed in the CAA section 107 of title 1. This 
action does not contain any information collection activities.

C. Regulatory Flexibility Act (RFA)

    This final rule is not subject to the RFA. The RFA applies only to 
rules subject to notice-and-comment rulemaking requirements under the 
Administrative Procedure Act (APA), 5 U.S.C. 553, or any other statute. 
This rule is not subject to notice-and-comment requirements under the 
APA but is subject to the CAA section 107(d)(2)(B) which does not 
require a notice-and-comment rulemaking to take this action.

D. Unfunded Mandates Reform Act (UMRA)

    This action does not contain any unfunded mandates as described by 
URM, 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.

E. Executive Order 13132: Federalism

    This final 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.

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

    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 primary SO2 NAAQS. 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 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 does 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. The EPA also sent individualized letters to

[[Page 45045]]

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 designations for the SO2 
standard and offered tribal leaders the opportunity for consultation. 
These communications provided opportunities for tribes to voice 
concerns to the EPA about the general designations process for the 2010 
primary SO2 NAAQS, as well as concerns specific to a tribe, 
and informed the EPA about key tribal concerns regarding designations 
as the rule was under development. For this second round of 
SO2 designations, the EPA sent additional letters to tribes 
that could potentially be affected and offered additional opportunities 
for participation in the designations process. The communication 
letters to the tribes are provided in the dockets for Round 1 (Docket 
ID NO. EPA-HQ-OAR-2012-0233 and Round 2 (Docket ID NO. EPA-HQ-OAR-2014-
0464).

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

    The EPA interprets Executive Order 13045 as applying only 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 concern an environmental 
health risk or safety risk.

H. 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.

I. National Technology Transfer and Advancement Act (NTTAA)

    This action does not involve technical standards.

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

    The EPA believes 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 Executive Order 12898 (59 FR 7629, February 16, 1994). The 
documentation for this decision is contained in Section IX of this 
document.

K. Congressional Review Act (CRA)

    The CRA, 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 action 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 
September 12, 2016.

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 final action designating areas for the 2010 primary 
SO2 NAAQS is ``nationally applicable'' within the meaning of 
section 307(b)(1). This final action establishes designations for areas 
across the U.S. for the 2010 primary SO2 NAAQS. At the core 
of this final action is the EPA's interpretation of 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 this final 
action is nationally applicable and is hereby publishing that finding 
in the Federal Register.
    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 U.S.C.C.A.N. 1402-03. Here, the scope and effect of this final 
action 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 action to be of ``nationwide scope or effect'' and for venue 
to be in the D.C. Circuit. Therefore, this final action is based on a 
determination by the Administrator of nationwide scope or effect, and 
the Administrator is hereby publishing that finding in the Federal 
Register.
    Thus, any petitions for review of these final designations must be 
filed in the Court of Appeals for the District of Columbia Circuit 
within 60 days from the date final action is published in the Federal 
Register.
