Abstract
The Environmental Protection Agency (EPA or Agency) is finalizing the determination that the Sullivan County, Tennessee, sulfur dioxide (SO<INF>2</INF>) nonattainment area (hereinafter referred to as "the Sullivan County Area" or "Area") failed to attain the 2010 1-hour SO<INF>2</INF> primary National Ambient Air Quality Standard (NAAQS or standard) by the applicable attainment date of October 4, 2018, based upon a weight of evidence analysis of available quality-assured and certified SO<INF>2</INF> ambient air monitoring data and SO<INF>2</INF> emissions data from January 2015 through December 2017. As a result of this determination, the State of Tennessee is required to submit by April 5, 2023, revisions to the Tennessee State Implementation Plan (SIP) that, among other things, provide for the attainment of the SO<INF>2</INF> NAAQS in the Sullivan County Area as expeditiously as practicable but no later than April 5, 2027.

Finding of Failure To Attain the 2010 Sulfur Dioxide Standard;
Tennessee; Sullivan County Nonattainment Area
AGENCY: Environmental Protection Agency (EPA).
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: The Environmental Protection Agency (EPA or Agency) is
finalizing the determination that the Sullivan County, Tennessee,
sulfur dioxide (SO<INF>2</INF>) nonattainment area (hereinafter
referred to as ``the Sullivan County Area'' or ``Area'') failed to
attain the 2010 1-hour SO<INF>2</INF> primary National Ambient Air
Quality Standard (NAAQS or standard) by the applicable attainment date
of October 4, 2018, based upon a weight of evidence analysis of
available quality-assured and certified SO<INF>2</INF> ambient air
monitoring data and SO<INF>2</INF> emissions data from January 2015
through December 2017. As a result of this determination, the State of
Tennessee is required to submit by April 5, 2023, revisions to the
Tennessee State Implementation Plan (SIP) that, among other things,
provide for the attainment of the SO<INF>2</INF> NAAQS in the Sullivan
County Area as expeditiously as practicable but no later than April 5,
2027.
DATES: This rule is effective May 5, 2022.

SUPPLEMENTARY INFORMATION:
I. Background
On January 13, 2022 (87 FR 2095), EPA published a notice of
proposed rulemaking (NPRM) proposing to find that the Sullivan County
Area failed to attain the 2010 1-hour SO<INF>2</INF> primary NAAQS \1\
by the applicable attainment
[[Page 19646]]
date of October 4, 2018, based upon a weight of evidence analysis of
available quality-assured and certified SO<INF>2</INF> ambient air
monitoring data and SO<INF>2</INF> emissions data from January 2015
through December 2017.
---------------------------------------------------------------------------
\1\ The Clean Air Act (CAA or Act) establishes a process for air
quality management through the establishment and implementation of
the NAAQS. On June 2, 2010, EPA revised the primary SO<INF>2</INF>
NAAQS, establishing a new 1-hour SO<INF>2</INF> standard of 75 parts
per billion (ppb). See 75 FR 35520 (June 22, 2010). After the
promulgation of a new or revised NAAQS, EPA is required to designate
all areas of the country pursuant to section 107(d)(1)-(2) of the
CAA.
---------------------------------------------------------------------------
EPA designated the Sullivan County Area as nonattainment on August
5, 2013,\2\ based on air quality monitoring data from an SO<INF>2</INF>
monitor operating at the time of designation (Air Quality System (AQS)
Site ID: 47-163-0007). The Sullivan County Area is comprised of a 3-
kilometer (km) radius circle centered around the B-253 powerhouse at
the Eastman Chemical Company facility in Kingsport, Tennessee
(Eastman), which encompasses this SO<INF>2</INF> monitor that was
operating at the time of designation.\3\ EPA's first round of
designations for the 2010 SO<INF>2</INF> NAAQS, including the Sullivan
County Area, became effective on October 4, 2013.
---------------------------------------------------------------------------
\2\ On August 5, 2013, EPA finalized its first round (round 1)
of designations for the 2010 primary SO<INF>2</INF> NAAQS.
Specifically, in the 2013 action, EPA designated 29 areas in 16
states as nonattainment for the 2010 SO<INF>2</INF> NAAQS, including
a portion of Sullivan County.
\3\ For exact descriptions of the Sullivan County Area, refer to
40 CFR 81.343.
---------------------------------------------------------------------------
Pursuant to CAA section 192(a), the attainment date for the Area
was no later than October 4, 2018, which is five years after the
effective date of the final action designating the Sullivan County Area
as nonattainment for the 2010 SO<INF>2</INF> NAAQS. Under section
179(c) of the CAA, within six months of the attainment date, EPA is
required to make a determination, based on the area's air quality as of
the attainment date, whether an area attained by that date. If EPA
determines that an area failed to attain by the attainment date, EPA is
required to publish that determination in the Federal Register. See CAA
section 179(c)(2).
On June 25, 2021, EPA entered into a consent decree with the Center
for Biological Diversity in the U.S. District Court for the Northern
District of California.\4\ The consent decree requires EPA to finalize
by March 31, 2022, a determination whether the Sullivan County Area
attained the 1-hour SO<INF>2</INF> standard by the October 4, 2018,
attainment date.
---------------------------------------------------------------------------
\4\ See Consent Decree entered June 25, 2021, (Docket ID: EPA-
R04-OAR-2021-0428), Center for Biological Diversity et al. v. EPA,
Case No. 3:20-cv-05436-EMC (N.D. Cal.) which is included in the
docket for this action.
---------------------------------------------------------------------------
In the January 13, 2022, NPRM, EPA evaluated whether the Sullivan
County Area attained the 2010 SO<INF>2</INF> NAAQS by the October 4,
2018, attainment date. For an area to attain the 2010 SO<INF>2</INF>
NAAQS by the October 4, 2018, attainment date, the design value based
upon monitored air quality data from 2015-2017 at each eligible
monitoring site must be equal to or less than 75 ppb for the 1-hour
standard. EPA developed a weight of evidence assessment based on
available quality-assured and certified air quality monitoring data,
and source-specific SO<INF>2</INF> emissions in the Area from January
2015 through December 2017 to support the proposed determination that
the Sullivan County Area did not attain the 1-hour SO<INF>2</INF>
standard by October 4, 2018.
Air monitoring data in the Sullivan County Area from January 1,
2015, to July 20, 2016, did not meet the quality assurance requirements
in 40 CFR part 58 Appendix A and, therefore, were not comparable to the
NAAQS. Consequently, a valid 2015-2017 design value could not be
determined for the Area. In lieu of a 2015-2017, 3-year design value,
EPA reviewed the available quality-assured ambient monitoring data from
July 20, 2016, to December 31, 2017, and annual and hourly
SO<INF>2</INF> emissions data at Eastman from January 1, 2015, to
December 31, 2017, to determine the air quality in the Sullivan County
Area as of the applicable attainment date. The available annual 99th
percentile daily maximum 1-hour average SO<INF>2</INF> data at each
state and local air monitoring station (SLAMS) site \5\ within the
Sullivan County Area for the 2015-2017 period are presented in Table 1.
---------------------------------------------------------------------------
\5\ See EPA's January 13, 2022, NPRM for additional details
regarding the Ross N. Robinson and Skyland Drive SLAMS sites. See 87
FR 2095.
Table 1--2015-2017 SO2 Monitoring Data for the Sullivan County Area

Skyland Dr. (47-163-6002)...... \a\ N/A \b\ 91 78 No.
----------------------------------------------------------------------------------------------------------------
Notes:
\a\ The SLAMS monitors did not collect data in 2015.
\b\ The Ross N. Robinson monitor had only two quarters of complete data in 2016 due to the monitor beginning
operation on July 21, 2016. The Skyland Drive monitor had only one quarter of complete data in 2016 due to the
monitor beginning operation on September 1, 2016.
Source: EPA AQS Design Value Report, retrieved September 14, 2021.
The data in Table 1 indicates that although the two sites in the
Sullivan County Area did not have complete data in 2015 and 2016 to
determine a 3-year design value, both monitors consistently measured
99th percentile daily maximum 1-hour SO<INF>2</INF> concentrations
above the 75 ppb level of the 1-hour NAAQS in 2016 and 2017, after
beginning operation in mid-2016. Both monitors have complete 2017
datasets.
The primary SO<INF>2</INF> emissions sources in the Area are the
coal-fired boilers at Eastman. EPA observed that the annual
SO<INF>2</INF> emissions and the hourly SO<INF>2</INF> emissions from
the Eastman boilers were significantly higher from January 1, 2015, to
June 30, 2016, when air monitoring data are not available, than from
July 1, 2016, through December 31, 2017, when air monitoring data are
available. Considering that the ambient measured concentrations
exceeded the level of the NAAQS in 2016 and 2017, when emissions from
the primary sources of SO<INF>2</INF> were lower than they were in
2015, EPA believes it is reasonable to expect that the 99th percentile
maximum daily 1-hour SO<INF>2</INF> concentration in 2015 likely also
exceeded the level of 75 ppb. Consequently, the three-year average of
the 99th percentile value for 2015 (likely exceeded the level of the
NAAQS), 2016 (exceeded the level of the NAAQS), and 2017 (exceeded the
level of the NAAQS) almost certainly would have resulted in a design
value that violated the NAAQS. Thus, EPA
[[Page 19647]]
finds that this analysis of available quality-assured and certified
ambient concentration data and SO<INF>2</INF> emissions data
demonstrates by a weight of evidence that the Sullivan County Area
failed to attain the 1-hour SO<INF>2</INF> NAAQS by the required
attainment date of October 4, 2018.
EPA's January 13, 2022, NPRM provided detailed assessments of the
SO<INF>2</INF> monitoring network and emissions data for the primary
SO<INF>2</INF>-emitting sources in the Area at Eastman. The NPRM also
provided additional background information on the promulgation of the
2010 SO<INF>2</INF> NAAQS, as well as the designation of the Sullivan
County Area under the CAA, and EPA's obligation under CAA section
179(c)(1) to determine if an area attained by the statutory attainment
date. Lastly, the January 13, 2022, NPRM discussed the consequences for
SO<INF>2</INF> nonattainment areas that failed to attain the 1-hour
SO<INF>2</INF> standard by the October 4, 2018, attainment date.
Comments on the January 13, 2022, NPRM were due on or before February
14, 2022.
II. Response to Comments
EPA received two comments on the January 13, 2022, NPRM, which are
included in the docket for this action. The comments do not object to
the proposed conclusion that the Sullivan County Area failed to timely
attain the NAAQS and are generally in favor of the proposed finding set
forth in the January 13, 2022, proposed rulemaking. EPA summarizes and
responds to the comments below.
Comment 1: The commenter discusses the findings that EPA outlined
in the January 13, 2022, NPRM and generally agrees that a ``SIP is
needed to more closely monitor Sullivan County and hold them
accountable to following the emission standards.'' The commenter notes
that EPA cites to CAA section 179(d) for the consequences for the
failure to meet the SO<INF>2</INF> standard. In addition, the commenter
expresses concern that the required SIP ``simply passes on
responsibility to the State'' and will not address the problem quickly
and suggests EPA ``handle the situation.'' The commenter believes EPA
has jurisdiction due to the nature of the SO<INF>2</INF> emissions
impacting multiple states and that fines should be imposed on the
responsible organizations.
Response 1: The commenter does not disagree with EPA's proposed
determination that the Sullivan County, Tennessee SO<INF>2</INF>
nonattainment area did not attain the 1-hour standard by the October 4,
2018, statutory attainment date. The commenter also supports the
requirement for Tennessee to submit a SIP one year after EPA's finding
that will provide attainment of the SO<INF>2</INF> standard in the
nonattainment area by a new statutory attainment date pursuant to the
requirements established at 179(d) of the CAA.
The commenter, however, expresses concern with relying on the State
to address the problem, and suggests it would be ideal for EPA to
handle the situation. The commenter asserts that EPA should levy fines
and should have jurisdiction because of the nature of SO<INF>2</INF>
emissions impacting multiple states. As acknowledged by the commenter,
EPA is taking this action pursuant to CAA section 179, which specifies
the consequences of EPA's determination that the Area did not attain
the air quality standard by the applicable attainment date.
Specifically, Section 179(d) requires each state with a nonattainment
area that fails to attain the standard by the applicable attainment
date to submit a SIP revision meeting the requirements of CAA sections
110 and 172 within one year after EPA publishes notice of its
determination. Section 172 requires the revision to include, among
other elements, a demonstration of attainment (within the period
prescribed by CAA section 179(d)), reasonable further progress, and
contingency measures. In addition, under CAA section 179(d)(2), the SIP
revision must include such additional measures as EPA may reasonably
prescribe, including all measures that can be feasibly implemented in
the area in light of technological achievability, costs, and any non-
air quality and other air quality-related health and environmental
impacts.\6\
---------------------------------------------------------------------------
\6\ At this time, EPA is not prescribing any additional measures
for the Sullivan County Area under CAA section 179(d)(2).
---------------------------------------------------------------------------
The relevance of the commenter's statements that EPA should have
jurisdiction because of the nature of SO<INF>2</INF> emissions
impacting multiple states, and that fines should be imposed on the
responsible organizations, is unclear. The source-specific nature of
the SO<INF>2</INF> standard is not relevant to EPA's obligations
prescribed under the Act to ensure states comply with CAA planning
requirements within the statutory timeframes. EPA appreciates the
commenter's concern and believes the CAA clearly establishes the
State's and EPA's respective responsibilities to ensure nonattainment
areas demonstrate expeditious attainment of the standards within the
period prescribed by CAA section 179(d). Regarding SO<INF>2</INF>
emissions impacting multiple states, separate CAA provisions in section
110(a)(2)(D) require SIPs to contain adequate provisions to prohibit
source emission activity that could impact another state's ability to
attain or maintain the SO<INF>2</INF> standard.\7\
---------------------------------------------------------------------------
\7\ Sections 110(a)(1) and (2) of the CAA require each state to
adopt and submit a SIP for the implementation, maintenance, and
enforcement of each NAAQS promulgated by EPA. This includes CAA
section 110(a)(2)(D), which requires SIPs to (i) contain adequate
provisions prohibiting any source or other type of emissions
activity within a state from emitting any air pollutants in amounts
which will (I) contribute significantly to nonattainment or
interfere with maintenance of the NAAQS in any other state, or (II)
interfere with measures required to prevent significant
deterioration of air quality or to protect visibility. EPA has
considered or will consider the adequacy of Tennessee's SIP for
these interstate provisions separately. EPA approved the interstate
provisions of Tennessee's SIP for the 2010 SO<INF>2</INF> NAAQS of
110(a)(2)(D)(i)(II) on November 28, 2016, and September 24, 2018
(see 81 FR 85410 and 83 FR 48237, respectively), and intends to act
on the section110(a)(2)(D)(i)(I) interstate transport SIP provisions
separately.
---------------------------------------------------------------------------
Comment 2: The commenter expresses concern about the proposed rule
only addressing the SO<INF>2</INF> NAAQS in Sullivan County, Tennessee,
and notes the importance of the proposed rule in maintaining the safety
of the people. The commenter also brings up negative impacts from
SO<INF>2</INF> on human health and the environment and states that
``that this is an important issue that I hope gets passed.''
Response 2: The commenter does not object to EPA's proposed
determination that the Sullivan County Area failed to timely attain the
NAAQS. EPA appreciates the commenter's acknowledgement of the health
and environmental impacts from SO<INF>2</INF> pollution. Regarding the
commenter's impression that the rule is only beneficial to those living
in Sullivan County, EPA notes that the finding of failure to attain is
specific to a portion of Sullivan County, Tennessee surrounding Eastman
Chemical based on the Agency's 2013 determination that the Area was not
attaining the 1-hour SO<INF>2</INF> standard. Since 2013, EPA has
determined that areas in the vicinity of large SO<INF>2</INF>-emitting
sources in the rest of the state are meeting the health-based 1-hour
SO<INF>2</INF> standard based on an assessment of available air quality
data. Furthermore, based on EPA's 2010 promulgation of the 1-hour
SO<INF>2</INF> standard, states were required to submit a SIP revision
to EPA to ensure their SIPs have the necessary provisions to provide
for the implementation, attainment, and maintenance of the standard
pursuant to section 110(a)(1) and 110(a)(2) of the CAA. Among other
elements, this revision must include necessary or appropriate
SO<INF>2</INF> emission limits and standards, an appropriate air
quality monitoring network, and a
[[Page 19648]]
permitting program to prevent any construction of new sources or source
modifications from deteriorating air quality in areas meeting the
NAAQS.
III. Final Action
EPA is taking final action to determine that the Sullivan County
Area failed to attain the 2010 1-hour primary SO<INF>2</INF> NAAQS by
the applicable attainment date of October 4, 2018. As a result of this
determination, the State of Tennessee is required under CAA section
179(d) to submit revisions to the Tennessee SIP for the Sullivan
County, Tennessee SO<INF>2</INF> nonattainment area to, among other
elements, provide for the attainment of the respective standard as
expeditiously as practicable but no later than April 5, 2027. At this
time, EPA is not prescribing additional measures for the SO<INF>2</INF>
SIP revisions under CAA section 179(d)(2). Tennessee is required under
CAA section 179(d) to submit a SIP revision meeting the requirements of
sections 110 and 172 of the CAA to EPA by April 5, 2023.
IV. Statutory and Executive Order Reviews
Additional information about these statutes and Executive Orders
can be found at <a href="http://www2.epa.gov/laws-regulations/laws-and-executive-orders">http://www2.epa.gov/laws-regulations/laws-and-executive-orders</a>.
A. Executive Order 12866: Regulatory Planning and Review, and Executive
Order 13563: Improving Regulation and Regulatory Review
This action is not a significant regulatory action and therefore
was not submitted to the Office of Management and Budget (OMB) for
review.
B. Paperwork Reduction Act (PRA)
This action does not impose an information collection burden under
the provisions of the PRA because it does not contain any information
collection activities.
C. Regulatory Flexibility Act (RFA)
I certify that this action will not have a significant economic
impact on a substantial number of small entities under the RFA. This
action will not impose any requirements on small entities.
D. Unfunded Mandates Reform Act (UMRA)
This action does not contain any unfunded mandate of $100 million
or more, as described in UMRA (2 U.S.C. 1531-1538) and does not
significantly or uniquely affect small governments. This action itself
imposes no enforceable duty on any state, local, or tribal governments,
or the private sector.
E. 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.
F. Executive Order 13175, Consultation and Coordination With Indian
Tribal Governments
This action does not have tribal implications as specified in
Executive Order 13175. The finding of failure to attain SO<INF>2</INF>
NAAQS does not apply to tribal areas, and the rule does not impose a
burden on Indian reservation lands or other areas where EPA or an
Indian tribe has demonstrated that a tribe has jurisdiction. Thus, this
rule does not have tribal implications and will not impose substantial
direct costs on tribal governments or preempt tribal law as specified
by Executive Order 13175.
G. Executive Order 13045, Protection of Children From Environmental
Health Risks and Safety Risks
EPA interprets Executive Order 13045 as applying only to those
regulatory actions that concern environmental health or safety risks
that 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 the effect of this action is to trigger additional
planning requirements under the CAA. This action 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 rule 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 rulemaking does not involve technical standards.
J. Executive Order 12898: Federal Actions To Address Environmental
Justice in Minority Populations and Low-Income Populations
EPA believes that this action does not have disproportionately high
and adverse human health or environmental effects on minority
populations, low-income populations and/or indigenous peoples, as
specified in Executive Order 12898 (59 FR 7629, February 16, 1994).
This action triggers additional planning requirements under the CAA.
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
United States. 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 United States 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).
L. Judicial Review
Under section 307(b)(1) of the CAA, petitions for judicial review
of this action must be filed in the United States Court of Appeals for
the appropriate circuit by June 6, 2022. Filing a petition for
reconsideration by the Administrator of this final rule does not affect
the finality of this action for the purposes of judicial review nor
does it extend the time within which a petition for judicial review may
be filed, and shall not postpone the effectiveness of such rule or
action. This action may not be challenged later in proceedings to
enforce its requirements. See section 307(b)(2).
