Air Plan Approval and Air Quality Designation; TN; Redesignation 
of the Knoxville 1997 Annual PM<INF>2.5</INF> Nonattainment Area to 
Attainment

AGENCY: Environmental Protection Agency (EPA).

ACTION: Final rule.

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

SUMMARY: On December 20, 2016, Tennessee, through the Tennessee 
Department of Environment and Conservation (TDEC), submitted a request 
for the Environmental Protection Agency (EPA) to redesignate the 
Knoxville, Tennessee fine particulate matter (PM<INF>2.5</INF>) 
nonattainment area (hereinafter referred to as the ``Knoxville Area'' 
or ``Area'') to attainment for the 1997 Annual PM<INF>2.5</INF> 
national ambient air quality standards (NAAQS) and to approve a state 
implementation plan (SIP) revision containing a maintenance plan, a 
reasonably available control measures (RACM) determination, and source-
specific requirements for the Area. EPA is approving Tennessee's RACM 
determination for the Knoxville Area and incorporating it into the SIP; 
incorporating source-specific requirements for two sources in the Area 
into the SIP; determining that the Knoxville Area is attaining the 1997 
Annual PM<INF>2.5</INF> NAAQS based on 2013-2015 data; approving 
Tennessee's plan for maintaining the 1997 Annual PM<INF>2.5</INF> NAAQS 
for the Knoxville Area (maintenance plan), including the associated 
motor vehicle emission budgets (MVEBs) for nitrogen oxides 
(NO<INF>X</INF>) and direct PM<INF>2.5</INF> for the years 2014 and 
2028, and incorporating it into the SIP; and redesignating the 
Knoxville Area to attainment for the 1997 Annual PM<INF>2.5</INF> 
NAAQS.

DATES: This rule will be effective August 29, 2017.

SUPPLEMENTARY INFORMATION:

I. Background

    On July 18, 1997, EPA promulgated the first air quality standards 
for PM<INF>2.5</INF>. EPA promulgated an annual standard at a level of 
15.0 micrograms per cubic meter ([mu]g/m\3\), based on a 3-year average 
of annual mean PM<INF>2.5</INF> concentrations. In the same rulemaking, 
EPA promulgated a 24-hour standard of 65 [mu]g/m\3\, based on a 3-year 
average of the 98th percentile of 24-hour concentrations. On October 
17, 2006 (71 FR 61144), EPA retained the annual average NAAQS at 15.0 
[mu]g/m\3\ but revised the 24-hour NAAQS to 35 [mu]g/m\3\, based again 
on the 3-year average of the 98th percentile of 24-hour concentrations.
    On January 5, 2005, at 70 FR 944, and supplemented on April 14, 
2005, at 70 FR 19844, EPA designated the Knoxville Area as 
nonattainment for the 1997 Annual PM<INF>2.5</INF> NAAQS. All 1997 
PM<INF>2.5</INF> NAAQS areas were designated under title I, part D, 
subpart 1 (hereinafter ``Subpart 1''). Subpart 1 contains the general 
requirements for nonattainment areas for any pollutant governed by a 
NAAQS and is less prescriptive than the other subparts of title I, part 
D. On April 25, 2007 (72 FR 20586), EPA promulgated its Clean Air Fine 
Particle Implementation Rule, codified at 40

[[Page 40954]]

CFR part 51, subpart Z, in which the Agency provided guidance for state 
and tribal plans to implement the 1997 PM<INF>2.5</INF> NAAQS. The 
United States Court of Appeals for the District of Columbia Circuit 
(D.C. Circuit) remanded the Clean Air Fine Particle Implementation Rule 
and the final rule entitled ``Implementation of the New Source Review 
(NSR) Program for Particulate Matter Less than 2.5 Micrometers 
(PM<INF>2.5</INF>)'' (73 FR 28321, May 16, 2008) (collectively, ``1997 
PM<INF>2.5</INF> Implementation Rules'') to EPA on January 4, 2013, in 
Natural Resources Defense Council v. EPA, 706 F.3d 428 (D.C. Cir. 
2013). The Court found that EPA erred in implementing the 1997 
PM<INF>2.5</INF> NAAQS pursuant to the general implementation 
provisions of Subpart 1, rather than the particulate matter-specific 
provisions of title I, part D, subpart 4 (hereinafter ``Subpart 4'').
    On June 2, 2014, EPA published a rule entitled ``Identification of 
Nonattainment Classification and Deadlines for Submission of State 
Implementation Plan (SIP) Provisions for the 1997 Fine Particle 
(PM<INF>2.5</INF>) National Ambient Air Quality Standard (NAAQS) and 
2006 PM<INF>2.5</INF> NAAQS''. See 79 FR 31566. In that rule, the 
Agency responded to the D.C. Circuit's January 2013 decision by 
identifying all PM<INF>2.5</INF> nonattainment areas for the 1997 and 
2006 PM<INF>2.5</INF> NAAQS as ``moderate'' nonattainment areas under 
Subpart 4, and by establishing a new SIP submission date of December 
31, 2014, for moderate area attainment plans and for any additional 
attainment-related or nonattainment new source review plans necessary 
for areas to comply with the requirements applicable under Subpart 4. 
Id. at 31567-70.
    Based on its moderate nonattainment area classification, Tennessee 
was required to submit a SIP revision addressing RACM pursuant to CAA 
section 172(c)(1) and section 189(a)(1)(C) for the Area. Although EPA 
does not believe that section 172(c)(1) and section 189(a)(1)(C) RACM 
must be approved into a SIP prior to redesignation of an area to 
attainment once that area is attaining the NAAQS, EPA is approving 
Tennessee's RACM determination and incorporating it into its SIP 
pursuant to a recent decision by the United States Court of Appeals for 
the Sixth Circuit in Sierra Club v. EPA, 793 F.3d 656 (6th Cir. 2015).
    In a notice of proposed rulemaking (NPRM) published on May 30, 2017 
(82 FR 24636), EPA proposed to: (1) Approve Tennessee's RACM 
determination for the Knoxville Area pursuant to CAA sections 172(c)(1) 
and 189(a)(1)(C) and incorporate it into the SIP; (2) determine that 
the Knoxville Area is attaining the 1997 Annual PM<INF>2.5</INF> NAAQS 
based on 2013-2015 air quality data; (3) approve Tennessee's 
maintenance plan for the Knoxville Area, including the 2014 and 2028 
MVEBs for PM<INF>2.5</INF> and NO<INF>X</INF>, and incorporate it into 
the SIP; (4) incorporate source-specific requirements for two sources 
located in the Area--the Tennessee Valley Authority (TVA) Bull Run 
Fossil Plant and TVA Kingston Fossil Plant--into the SIP; and (5) 
redesignate the Knoxville Area to attainment for the 1997 Annual 
PM<INF>2.5</INF> NAAQS.\1\ The details of Tennessee's submittal and the 
rationale for EPA's actions are further explained in the NPRM. EPA did 
not receive any adverse comments on the proposed action.
---------------------------------------------------------------------------

    \1\ In a notice published in the Federal Register on March 10, 
2017, EPA announced that it had found the MVEBs for the Knoxville 
Area for the 1997 Annual PM<INF>2.5</INF> NAAQS adequate for 
transportation conformity purposes. See 82 FR 13337.
---------------------------------------------------------------------------

II. What are the effects of these actions?

    EPA's approval changes the legal designation of Anderson, Blount, 
Knox, and Loudon Counties and a portion of Roane County for the 1997 
Annual PM<INF>2.5</INF> NAAQS, found at 40 CFR part 81, from 
nonattainment to attainment. Approval of Tennessee's associated SIP 
revision also incorporates a plan for maintaining the 1997 Annual 
PM<INF>2.5</INF> NAAQS in the Area through 2028, Tennessee's RACM 
determination, and source-specific requirements for two sources in the 
Area into the Tennessee SIP. The maintenance plan includes contingency 
measures to remedy any future violations of the 1997 Annual 
PM<INF>2.5</INF> NAAQS and procedures for evaluation of potential 
violations. The maintenance plan also includes NO<INF>X</INF> and 
PM<INF>2.5</INF> MVEBs for 2014 and 2028 for the Knoxville Area. The 
2014 and 2028 PM<INF>2.5</INF> MVEBs are 444.78 tons per year (tpy) and 
245.00 tpy, respectively. The 2014 and 2028 NO<INF>X</INF> MVEBs are 
15,597.73 tpy and 7,171.14 tpy, respectively.
    In the Fine Particulate Matter National Ambient Air Quality 
Standards: State Implementation Plan Requirements final rule 
(PM<INF>2.5</INF> SIP Requirements Rule), EPA revoked the 1997 primary 
Annual PM<INF>2.5</INF> NAAQS in areas that had always been attainment 
for that NAAQS, and in areas that had been designated as nonattainment 
but that were redesignated to attainment before October 24, 2016, the 
rule's effective date. See 81 FR 58010 (August 24, 2016). EPA also 
finalized a provision that revokes the 1997 primary Annual 
PM<INF>2.5</INF> NAAQS in areas that are redesignated to attainment for 
that NAAQS after October 24, 2016, effective on the effective date of 
the redesignation of the area to attainment for that NAAQS. See 40 CFR 
50.13(d).
    EPA is finalizing the redesignation of the Knoxville Area to 
attainment for the 1997 Annual PM<INF>2.5</INF> NAAQS and finalizing 
the approval of the CAA section 175A maintenance plan for the 1997 
primary Annual PM<INF>2.5</INF> NAAQS.\2\ Therefore, the 1997 primary 
Annual PM<INF>2.5</INF> NAAQS will be revoked in the Knoxville Area on 
the effective date of this redesignation, August 29, 2017. Beginning on 
that date, the Area will no longer be subject to transportation or 
general conformity requirements for the 1997 Annual PM<INF>2.5</INF> 
NAAQS due to the revocation of the primary NAAQS. See 81 FR 58125 
(August 24, 2016). The Area is required to implement the CAA section 
175A maintenance plan for the 1997 primary Annual PM<INF>2.5</INF> 
NAAQS that is being approved in this action and the prevention of 
significant deterioration program for the 1997 Annual PM<INF>2.5</INF> 
NAAQS. The approved maintenance plan can only be revised if the 
revision meets the requirements of CAA section 110(l) and, if 
applicable, CAA section 193. The Area is not required to submit a 
second 10-year maintenance plan for the 1997 primary Annual 
PM<INF>2.5</INF> NAAQS. See 81 FR 58144 (August 24, 2016).
---------------------------------------------------------------------------

    \2\ CAA section 175A(a) establishes the maintenance plan 
requirements that must be fulfilled by nonattainment areas in order 
to be redesignated to attainment. That section only requires that 
nonattainment areas for the primary standard submit a plan 
addressing maintenance of the primary NAAQS in order to be 
redesignated to attainment; it does not require nonattainment areas 
for secondary NAAQS to submit maintenance plans in order to be 
redesignated to attainment. See 42 U.S.C. 7505a(a).
---------------------------------------------------------------------------

III. Incorporation by Reference

    In this rule, EPA is finalizing regulatory text that includes 
incorporation by reference. In accordance with requirements of 1 CFR 
51.5, EPA is finalizing the incorporation by reference of the following 
Title V permit limits and conditions in Appendix L of Tennessee's 
December 20, 2016 SIP revision, state effective on December 20, 2016: 
Permit conditions E3-4(a), (d), and (e), E3-15, and E3-16 for the TVA 
Kingston Fossil Plant, and permit conditions E3-4(a), (d), and (e), E3-
15, and E3-16 for the TVA Bull Run Fossil Plant. Therefore, these 
materials have been approved by EPA for inclusion in the State 
implementation plan, have been incorporated by reference by EPA into 
that plan, are fully federally enforceable under sections 110 and 113 
of the CAA as of

[[Page 40955]]

the effective date of the final rulemaking of EPA's approval, and will 
be incorporated by reference by the Director of the Federal Register in 
the next update to the SIP compilation.\3\ EPA has made, and will 
continue to make, these materials generally available through 
www.regulations.gov and/or at the EPA Region 4 Office (please contact 
the person identified in the For Further Information Contact section of 
this preamble for more information).
---------------------------------------------------------------------------

    \3\ 62 FR 27968 (May 22, 1997).
---------------------------------------------------------------------------

IV. Final Actions

    EPA is taking the following final actions: (1) Approving 
Tennessee's RACM determination for the Knoxville Area pursuant to CAA 
sections 172(c)(1) and 189(a)(1)(C) and incorporating it into the SIP; 
(2) determining that the Area is attaining the 1997 Annual 
PM<INF>2.5</INF> NAAQS based on 2013-2015 data; (3) approving 
Tennessee's plan for maintaining the 1997 Annual PM<INF>2.5</INF> NAAQS 
(maintenance plan), including the associated 2014 and 2028 MVEBs for 
the Knoxville Area, and incorporating it into the Tennessee SIP; (4) 
incorporating source-specific requirements for two sources in the Area 
into the SIP; and (5) redesignating the Knoxville Area to attainment 
for the 1997 Annual PM<INF>2.5</INF> NAAQS.
    Approval of the redesignation request changes the official 
designation of Anderson, Blount, Knox, and Loudon Counties and a 
portion of Roane County for the 1997 Annual PM<INF>2.5</INF> NAAQS, 
found at 40 CFR part 81 from nonattainment to attainment.
    As mentioned above, the PM<INF>2.5</INF> SIP Requirements Rule 
provides that the 1997 PM<INF>2.5</INF> NAAQS will be revoked for any 
area that is redesignated for the NAAQS upon the effective date of the 
redesignation. Therefore, the 1997 primary Annual PM<INF>2.5</INF> 
NAAQS is revoked for the Knoxville Area on the effective date of this 
redesignation.
    EPA has determined that these actions are effective immediately 
upon publication under the authority of 5 U.S.C. 553(d). The purpose of 
the 30-day waiting period prescribed in section 553(d) is to give 
affected parties a reasonable time to adjust their behavior and prepare 
before the final rule takes effect. Section 553(d)(3) allows an 
effective date less than 30 days after publication ``as otherwise 
provided by the agency for good cause found and published with the 
rule.'' EPA finds good cause to make these actions effective 
immediately pursuant to section 553(d)(3) because they do not create 
any new regulatory requirements such that affected parties would need 
time to prepare before the actions take effect. The RACM determination 
does not create any new regulatory requirements because it concludes 
that no additional measures are necessary to meet the State's 
obligations to have fully adopted RACM; incorporating the 
aforementioned Title V permit terms and conditions for the TVA Bull Run 
Fossil Plant and the TVA Kingston Fossil Plant into the SIP does not 
create any new regulatory requirements because these sources were 
subject, and remain subject, to these terms and conditions through 
their Title V permits; and redesignating the Area to attainment, 
including the associated determination of attainment and maintenance 
plan approval, relieves the Area from certain CAA requirements that 
would otherwise apply to it. Because the redesignation relieves the 
Area from requirements, its immediate effective date is also authorized 
under section 553(d)(1) which allows an effective date less than 30 
days after publication if a substantive rule ``relieves a 
restriction.''

V. Statutory and Executive Order Reviews

    Under the CAA, redesignation of an area to attainment and the 
accompanying approval of a maintenance plan under section 107(d)(3)(E) 
are actions that affect the status of a geographical area and do not 
impose any additional regulatory requirements on sources beyond those 
imposed by state law. A redesignation to attainment does not in and of 
itself create any new requirements, but rather results in the 
applicability of requirements contained in the CAA for areas that have 
been redesignated to attainment. Moreover, the Administrator is 
required to approve a SIP submission that complies with the provisions 
of the Act and applicable Federal regulations. See 42 U.S.C. 7410(k); 
40 CFR 52.02(a). Thus, in reviewing SIP submissions, EPA's role is to 
approve state choices, provided that they meet the criteria of the CAA. 
Accordingly, these actions merely approve state law as meeting federal 
requirements and do not impose additional requirements beyond those 
imposed by state law. For that reason, these actions:
    <bullet> Are not significant regulatory actions subject to review 
by the Office of Management and Budget under Executive Order 12866 (58 
FR 51735, October 4, 1993) and 13563 (76 FR 3821, January, 21, 2011);
    <bullet> Do not impose an information collection burden under the 
provisions of the Paperwork Reduction Act (44 U.S.C. 3501 et seq.);
    <bullet> Are certified as not having a significant economic impact 
on a substantial number of small entities under the Regulatory 
Flexibility Act (5 U.S.C. 601 et seq.);
    <bullet> Do not contain any unfunded mandate or significantly or 
uniquely affect small governments, as described in the Unfunded 
Mandates Reform Act of 1995 (Pub. L. 104-4);
    <bullet> Do not have Federalism implications as specified in 
Executive Order 13132 (64 FR 43255, August 10, 1999);
    <bullet> Are not economically significant regulatory actions based 
on health or safety risks subject to Executive Order 13045 (62 FR 
19885, April 23, 1997);
    <bullet> Are not significant regulatory actions subject to 
Executive Order 13211 (66 FR 28355, May 22, 2001);
    <bullet> Are not subject to requirements of section 12(d) of the 
National Technology Transfer and Advancement Act of 1995 (15 U.S.C. 272 
note) because application of those requirements would be inconsistent 
with the CAA; and
    <bullet> Will not have disproportionate human health or 
environmental effects under Executive Order 12898 (59 FR 7629, February 
16, 1994).
    In addition, the SIP is not approved to apply on any Indian 
reservation land or in any other area where EPA or an Indian tribe has 
demonstrated that a tribe has jurisdiction. In those areas of Indian 
country, the rule does not have tribal implications as specified by 
Executive Order 13175 (65 FR 67249, November 9, 2000), nor will it 
impose substantial direct costs of tribal governments or preempt tribal 
law.
    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).
    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 October 30, 2017. Filing a

[[Page 40956]]

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).
