(c) EPA approved regulations.

(d) EPA-approved State Source-specific requirements.

(e) EPA-Approved Tennessee Non-Regulatory Provisions

The Tennessee plan was evaluated on the basis of the following classifications:

(a) With the exceptions set forth in this subpart, the Administrator approves Tennessee's plan for the attainment and maintenance of the national standards under section 110 of the Clean Air Act. Furthermore, the Administrator finds that the plan satisfies all requirements of part D, title 1, of the Clean Air Act as amended in 1977.

(b) New source review permits issued pursuant to section 173 of the Clean Air Act will not be deemed valid by EPA unless the provisions of Section V of the emission offset interpretative rule (Appendix S of 40 CFR part 51) are met.

(c) [Reserved]

(a) The information in this section is available in the 40 CFR, part 52 edition revised as of July 1, 1999, the 40 CFR, part 52, Volume 1 of 2 (§§ 52.01 to 52.1018) editions revised as of July 1, 2000 through July 1, 2011, and the 40 CFR, part 52, Volume 3 of 3 (§§ 52.2020 to End) editions revised as of July 1, 2012.

(b)-(f) [Reserved]

(a) The requirements of § 51.230(c) of this chapter are not met since the plan does not provide the legal authority for controlling motor vehicles during air pollution emergency episodes.

(b) The requirements of § 51.230(d) of this chapter are not met since statutory authority to prevent construction, modification, or operation of a facility, building, structure, or installation, or combination thereof, which indirectly results or may result in emissions of any air pollutant at any location which will prevent the maintenance of a national air quality standard is not adequate.

(c)(1) The requirements of § 51.230(b) of this chapter are not met since the definition of person set forth in the Tennessee Air Quality Act and in the State implementation plan does not include facilities owned or operated by the State. Therefore, section 53-3409(f) of the Tennessee Code Annotated and section 30 of Chapter II of the Tennessee Air Pollution Control Regulations are disapproved.

(2) Definition of person. For the purposes of the plan, person shall mean any individual, partnership, copartnership, firm, company, corporation, association, joint stock company, trust, estate, State-owned or operated facility, State agency, political subdivision, or any other legal entity, or their legal representatives, agents, or assigns.

(d) The requirements of § 51.230(b) of this chapter are not met since the State lacks legal authority, as a result of the enactment of House Bill 1490 by the 1974 Tennessee legislature, to control emissions from the quarrying and processing of agricultural limestone. Therefore, section 53-3424 of the Tennessee Code Annotated is disapproved.

(e) The requirements of § 51.230(b) of this chapter are not met since the State lacks legal authority, as a result of the enactment of House Bill 1845 by the 1974 Tennessee legislature, to control emissions from air contaminant sources which use woodwaste only as fuel. Therefore, the last sentence of section 53-3422 of the Tennessee Code Annotated is disapproved.

(a) Revisions to sections 7-3, 7-13, and 7-24 of the Tennessee regulations are approved. These amendments are in response to the Clean Air Act section 182(a)(2)(A) requirement to submit RACT rules correcting deficiencies in the existing SIP in accordance with EPA's pre-amendment guidance. These deficiencies were first noted in a letter from Greer Tidwell, the EPA Region IV Administrator, to Governor McWherter on May 26, 1988, and clarified in a letter dated June 10, 1988, from Winston Smith, EPA Region IV Air Division Director, to Paul Bontrager, Director of the Air Pollution Control Division of the Metropolitan Health Department for Nashville/Davidson County, and were further identified in EPA guidance including the Blue Book and the proposed Post-87 policy. The following deficiency in the Tennessee Regulations, however, has not been corrected.

(1) Section 7-25, “Recordkeeping and Reporting Requirements” Nashville/Davidson County committed in a letter dated May 7, 1991, to include a separate provision that requires records to be maintained for at least two years. This additional provision, which is scheduled for a July 15, 1992, public hearing, will be submitted to EPA shortly after that date and will be acted upon separately.

(2) In Section 7-3, Petition for Alternative Controls, the words “as applied” should be added to the term “VOC/gallon solids” as a clarification.

(3) The term “vapor-tight” should be defined in section 7-13.

(4) “Once-in/always-in” is missing from the applicability section of the individual rules.

(5) Section 7-25, “Recordkeeping and Reporting Requirements” should be revised to include additional requirements that would contain: units of compliance consistent with the performance requirements; applicable time periods for data entries; and a clear, separate provision that requires records to be kept.

(b)-(c) [Reserved]

(a) The requirements of § 51.152(a) of this chapter are not met since the plan does not provide for the enforcement of emission control actions for mobile sources during air pollution emergency episodes.

(a) Part D—Conditional approval. The Nashville-Davidson County regulation for the review of new sources and modifications in nonattainment areas is approved on condition that the State by October 31, 1984, submit a revision limiting source shutdown credit for offsets to replacement units, and, in the interim, assure implementation of the regulation in conformity with Federal requirements.

(b) Section 123—Conditional approval. The plan's provision for implementation of the requirements of section 123 of the Clean Air Act in Nashville-Davidson County is approved on condition that the State by October 31, 1984, submit:

(1) Definitions in the local regulation of nearby and excessive concentration and

(2) Provision in the local regulation for public notification and opportunity for hearing in cases where stack heights in excess of normal good engineering practice are proposed on the basis of fluid modeling demonstrations, and, in the interim, assure implementation of the local regulation in conformity with Federal requirements.

(c) The State of Tennessee proposed to delete section 1200-3-18-.03 “Standard for New Sources” from the Tennessee State Implementation Plan (SIP) and the Memphis-Shelby County portion of the Tennessee SIP. EPA is disapproving the deletion of this rule for the Tennessee SIP because Tennessee does not have federally approved New Source Review (NSR) regulations which apply to some of the sources in this chapter. EPA is approving the deletion of this rule for the Memphis submittal because the federally approved TN NSR applies to the Memphis-Shelby County area.

(d) The State of Tennessee proposed to delete rule 1200-3-18-.03 “Standard for New Sources” from the Tennessee State Implementation Plan (SIP). In paragraph (e) of this section, EPA disapproved the deletion of this rule because Tennessee did not have federally approved New Source Review (NSR) regulations that applied to some of the sources in this chapter. EPA is hereby approving the deletion of section 1200-3-18-.03 of the Tennessee SIP, and is deleting EPA's earlier disapproval in paragraph (e) of this section.

(a) The following portions of the revised Memphis and Shelby County regulations submitted on July 7, 1986, are disapproved because they are inconsistent with EPA policy and requirements:

(b) Knox County Regulation 25.2.B, submitted July 7, 1986, is disapproved because it is inconsistent with EPA policy and requirements.

(a) Part D conditional approval. The Chattanooga primary TSP plan's provisions for review of new sources and modifications in the nonattainment area are approved on condition that the State submit by December 31, 1987, a definition of the term Federally enforceable and provisions for making Federally enforceable all limitations, conditions, and offsets, including permit restrictions, relied upon under the plan, and in the interim, implement these provisions in a manner consistent with EPA requirements.

(b) In letters dated March 9 and April 15, 1988, the Tennessee Department of Health and Environment certified that no emission limits in the State's plan are based on dispersion techniques not permitted by EPA's stack height rules. This certification does not apply to: Dupont (43-07-02); Tennessee Valley Authority—Johnsonville (43-11-1 thru 10); Tennessee Chemical Company (70-04-21); Tennessee Eastman (82-03-15-19); A.E. Staley (53-81-18, 19, 34, 31); Cargill Inc., Memphis; and Grace Chemical Company, Millington.

(c) Determination of Attaining Data. EPA has determined, as of May 31, 2011, the Chattanooga, Tennessee, nonattainment area has attaining data for the 1997 annual PM2.5 NAAQS. This determination, in accordance with 40 CFR 52.1004(c), suspends the requirements for this area to submit an attainment demonstration, associated reasonably available control measures, a reasonable further progress plan, contingency measures, and other planning SIPs related to attainment of the standard for as long as this area continues to meet the 1997 annual PM2.5 NAAQS.

(d) Determination of attaining data. EPA has determined the Knoxville, Tennessee, nonattainment area has attaining data for the 1997 annual PM2.5 NAAQS. This determination, in accordance with 40 CFR 51.1004(c), suspends the requirements for this area to submit an attainment demonstration, associated reasonably available control measures, a reasonable further progress plan, contingency measures, and other planning SIPs related to attainment of the standard for as long as this area continues to meet the 1997 annual PM2.5 NAAQS.

(e) Determination of attaining data. EPA has determined Knoxville-Sevierville-La Follette, Tennessee, nonattainment area has attaining data for the 2006 24-hour PM2.5 NAAQS. This determination, in accordance with 40 CFR 51.1004(c), suspends the requirements for this area to submit an attainment demonstration, associated reasonably available control measures, a reasonable further progress plan, contingency measures, and other planning SIPs related to attainment of the standard for as long as this area continues to meet the 2006 24-hour PM2.5 NAAQS.

(f) Determination of attainment. Effective June 9, 2017, the EPA has determined that, based on 2013 to 2015 ambient air quality data, the Knoxville-Sevierville-La Follette, Tennessee PM2.5 nonattainment area has attained the 2006 24-hour PM2.5 NAAQS by the applicable attainment date of December 31, 2015. Therefore, the EPA has met the requirement pursuant to CAA section 188(b)(2) to determine whether the area attained the standard. The EPA also has determined that the Knoxville-Sevierville-La Follette, Tennessee nonattainment area will not be reclassified for failure to attain by its applicable attainment date under section 188(b)(2).

(g) Effective May 5, 2022, EPA has determined that the Sullivan County SO2 nonattainment area (NAA) has failed to attain the 2010 1-hour primary sulfur dioxide (SO2) national ambient air quality standard (NAAQS) by the applicable attainment date of October 4, 2018. This determination triggers the requirements of CAA section 179(d) for the State of Tennessee to submit a revision to the Tennessee State Implementation Plan (SIP) for the Sullivan County SO2 NAA to EPA by April 5, 2023. The SIP revision must, among other elements, provide for the attainment of the 1-hour primary SO2 NAAQS in the Sullivan County SO2 NAA as expeditiously as practicable but no later than April 5, 2022.

Based upon EPA's review of the air quality data for the 3-year period 2007-2009, EPA determined that the Chattanooga, Alabama-Georgia-Tennessee PM2.5 nonattainment Area attained the 1997 annual PM2.5 NAAQS by the applicable attainment date of April 5, 2010. Therefore, EPA has met the requirement pursuant to CAA section 179(c) to determine, based on the Area's air quality as of the attainment date, whether the Area attained the standard. EPA also determined that the Chattanooga, Alabama-Georgia-Tennessee PM2.5 nonattainment Area is not subject to the consequences of failing to attain pursuant to section 179(d).

(a)(1) Paragraph 1200-3-9-.01(4)-(0)-2. of Tennessee's regulations is disapproved because it does not require that the consent of the Governor(s) of affected states be obtained when innovative technology waivers are granted. EPA retains permitting authority for sources requesting innovative technology waivers which would significantly impact air quality in adjacent states.

(2) Tennessee's definition of stationary source specifically excludes the activities of any Vessel. This exclusion is not currently approvable and EPA is deferring action on it pending final rulemaking on the issue. EPA retains authority for permits which involve vessel emissions where a source is not willing to include all vessel emissions in the definition of source.

(b) The requirements of § 52.21 except paragraph (a)(1) are hereby incorporated and made part of the applicable SIP for the State of Tennessee for the following purposes:

(1) Permitting of sources requesting innovative technology waivers which would significantly impact air quality in adjacent states.

(2) Permitting of sources involving vessel emissions where the source is unwilling to include all vessel emissions in the definition of source.

(c) All applications and other information required pursuant to § 52.21 from sources located in the State of Tennessee shall be submitted to the appropriate state or local agency for which the source is located, rather than to EPA's Region 4 office: Tennessee Department of Environment and Conservation, Division of Air Pollution Control, William R. Snodgrass Tennessee Tower, 312 Rosa L. Parks Avenue, 15th Floor, Nashville, Tennessee 37243; Knox County Air Quality Management—Department of Public Health, 140 Dameron Avenue, Knoxville, Tennessee 37917; Metro Public Health Department, Pollution Control Division, 2500 Charlotte Ave., Nashville, Tennessee 37209; Chattanooga-Hamilton County Air Pollution Control Bureau, 6125 Preservation Drive, Chattanooga, Tennessee 37416; or Shelby County Health Department, Pollution Control Section, 814 Jefferson Avenue, Memphis, Tennessee 38105.

(a) Determination—EPA is determining that, as of August 8, 1995, the Nashville ozone nonattainment area has attained the ozone standard and that the reasonable further progress and attainment demonstration requirements of section 182(b)(1) and related requirements of section 172(c)(9) of the Clean Air Act do not apply to the area for so long as the area does not monitor any violations of the ozone standard. If a violation of the ozone NAAQS is monitored in the Nashville ozone nonattainment area, these determinations shall no longer apply.

(b) Nonregulatory provisions for the implementation of a basic I/M program in Rutherford, Sumner, Williamson, and Wilson Counties, submitted on July 13, 1994, were approved by EPA on September 26, 1995.

(c) Determination of Attaining Data. EPA has determined, as of October 12, 2010 the Knoxville, Tennessee nonattainment area has attaining data for the 1997 8-hour ozone NAAQS. This determination, in accordance with 40 CFR 51.918, suspends the requirements for this area to submit an attainment demonstration, associated reasonably available control measures, a reasonable further progress plan, contingency measures, and other planning SIPs related to attainment of the standards for as long as this area continues to meet the 1997 8-hour ozone NAAQS.

(d) Determination of attainment. The EPA has determined, as of June 3, 2016, that based on 2011 to 2013 ambient air quality data, the Knoxville, TN and Memphis, TN-MS-AR 2008 ozone Marginal nonattainment areas have attained the 2008 ozone NAAQS. Therefore, the EPA has met the requirement pursuant to CAA section 181(b)(2)(A) to determine, based on an area's air quality data as of the attainment date, whether the areas attained the standard. The EPA also determined that the Knoxville, TN and Memphis, TN-MS-AR nonattainment areas will not be reclassified for failure to attain by their applicable attainment date under section 181(b)(2)(A).

(a) The Tennessee Department of Environment and Conservation has submitted revisions to the Tennessee SIP on October 6, 1994. These revisions address the requirements necessary to change a lead nonattainment area to attainment. The maintenance plan for the Fayette County area near Rossville, Tennessee is comprised of a maintenance demonstration and NSR/PSD program. For areas where the only lead source has shut down, these components are sufficient for an approvable maintenance plan. The State's maintenance plan is complete and satisfies all of the requirements of section 175(A) of the CAA.

(b) Determination of attaining data. EPA has determined the Bristol, Tennessee, nonattainment area has attaining data for the 2008 lead (Pb) NAAQS. This clean data determination suspends the requirements for this area to submit an attainment demonstration, associated reasonably available control measures, a reasonable further progress plan, contingency measures, and other planning SIPs related to attainment of the standard for as long as this area continues to meet the 2008 Pb NAAQS.

Approval. EPA is approving the section 182(f) oxides of nitrogen (NOX) reasonably available control technology (RACT) and NOX conformity exemption request submitted by the Tennessee Department of Environment and Conservation on March 21, 1995, for the five county middle Tennessee (Nashville) ozone moderate nonattainment area. This approval exempts the area from implementing federal NOX RACT on major sources of NOX and exempts Tennessee from NOX conformity. This approval does not exempt sources from any State required or State Implementation Plan (SIP) approved NOX controls. If a violation of the ozone NAAQS occurs in the area, the exemption from the requirement of section 182(f) of the CAA in the applicable area shall not apply.

(a) This section identified the original “Air Implementation Plan for the State of Tennessee” and all revisions submitted by Tennessee that were federally approved prior to December 1, 1998. The information in this section is available in the 40 CFR, part 52 edition revised as of July 1, 1999, the 40 CFR, part 52, Volume 2 of 2 (§§ 52.1019 to End) editions revised as of July 1, 2000 through July 1, 2011, and the 40 CFR, part 52, Volume 3 of 3 (§§ 52.2020 to End) editions revised as of July 1, 2012. The Nashville-Davidson portion of the Tennessee's SIP previously identified in section 52.2222(c) is also available in the above editions.
