AGENCY:

Environmental Protection Agency (EPA).

ACTION:

Final rule.

SUMMARY:

EPA is taking final action to approve a request submitted on February 26, 2009, from the State of Tennessee, through the Tennessee Department of Environment and Conservation (TDEC), Air Pollution Control Division, to redesignate the Tennessee portion of the bi-state Memphis, Tennessee-Arkansas 8-hour ozone nonattainment area (hereafter referred to as the “bi-state Memphis Area”) to attainment for the 1997 8-hour ozone national ambient air quality standards (NAAQS). The bi-state Memphis 1997 8-hour ozone NAAQS nonattainment area is composed of Shelby County, Tennessee and Crittenden County, Arkansas. EPA's approval of the redesignation request is based on the determination that the bi-state Memphis Area has met the criteria for redesignation to attainment set forth in the Clean Air Act (CAA), including the determination that the bi-state Memphis Area has attained the 1997 8-hour ozone standard. Additionally, EPA is approving a revision to the Tennessee State Implementation Plan (SIP) including the 1997 8-hour ozone maintenance plan for Shelby County, Tennessee that contains the new 2006, 2009, 2017, and 2021 motor vehicle emission budgets (MVEBs) for nitrogen oxides (NOX) and volatile organic compounds (VOC) for Shelby County, Tennessee. This action also approves the emissions inventory submitted with the maintenance plan (under the CAA section 182(a)(1)). The State of Arkansas has submitted a similar redesignation request and maintenance plan for the Arkansas portion of this 1997 8-hour ozone area. EPA is taking action on Arkansas' redesignation request, emissions inventory and maintenance plan through a separate rulemaking action. On March 12, 2008, EPA issued a revised 8-hour ozone standard. EPA later announced on September 16, 2009, that it may reconsider this revised ozone standard. The current action, however, is being taken to address requirements under the 1997 8-hour ozone NAAQS. Requirements for the bi-state Memphis Area under the 2008 standard will be addressed in the future.

DATES:

Effective Date: This rule will be effective February 3, 2010.

I. What Is the Background for the Actions?

On February 26, 2009, the State of Tennessee, through TDEC, submitted a request to redesignate Shelby County, Tennessee (as part of the bi-state Memphis Area) to attainment for the 1997 8-hour ozone standard, and for EPA approval of the Tennessee SIP revision containing a maintenance plan for Shelby County, Tennessee. In an action published on November 19, 2009 (74 FR 59943), EPA proposed to approve the redesignation of Shelby County, Tennessee (as part of the bi-state Memphis Area) to attainment. EPA also proposed approval of Tennessee's plan for maintaining the 1997 8-hour NAAQS as a SIP revision, including the emissions inventory submitted pursuant to CAA section 182(a)(1); and proposed to approve the NOx and VOC MVEBs for Shelby County that were contained in the maintenance plan. In the November 19, 2009, proposed action, EPA also provided information on the status of its transportation conformity adequacy determination for the Shelby County NOX and VOC MVEBs. EPA received no comments on the November 19, 2009, proposal. Additionally, in a separate notice, EPA has already found the NOX and VOC MVEBs, as contained in Tennessee's maintenance plan for Shelby County, adequate for the purposes of transportation conformity. The MVEBs included in the maintenance plan area as follows:

Table 1—Shelby County VOC and NOX MVEBs

[Summer season tons per day]

Year2006200920172021
NOX55.87855.62055.17354.445
VOC25.21627.24018.32313.817

EPA's adequacy public comment period on these MVEBs (as contained in Tennessee's submittal) began on March 12, 2009, and closed on April 13, 2009. No comments were received during EPA's adequacy public comment period. In a letter dated September 18, 2009, EPA informed the State of Tennessee of its intent to make an affirmative adequacy determination for the MVEBs contained in this maintenance plan for Shelby County, Tennessee. On November 12, 2009 (74 FR 58277), EPA published a Federal Register notice deeming the MVEBs for Shelby County, Tennessee adequate for transportation conformity purposes. EPA provided a separate adequacy posting for the MVEBs in association with Crittenden County, Arkansas. The Crittenden County, Arkansas MVEBs (in association with the bi-state Memphis Area) were found adequate through a separate action published May 7, 2009 (74 FR 21356). As was discussed in greater detail in the November 19, 2009, proposal, this redesignation is for the 1997 8-hour ozone designations finalized in April 30, 2004 (69 FR 23857). Various aspects of EPA's Phase 1 8-hour ozone implementation rule were challenged in court and on December 22, 2006, the U.S. Court of Appeals for the District of Columbia Circuit (DC Circuit Court) vacated EPA's Phase 1 Implementation Rule for the 8-hour Ozone Standard. (69 FR 23951, April 30, 2004). South Coast Air Quality Management Dist. (SCAQMD) v. EPA, 472 F.3d 882 (DC Cir. 2006). On June 8, 2007, in response to several petitions for rehearing, the DC Circuit Court clarified that the Phase 1 Rule was vacated only with regard to those parts of the Rule that had been successfully challenged. Therefore, the Phase 1 Rule provisions related to classifications for areas currently classified under subpart 2 of title I, part D of the CAA as 8-hour nonattainment areas, the 8-hour attainment dates and the timing for emissions reductions needed for attainment of the 8-hour ozone NAAQS, remain effective. The June 8th decision left intact the Court's rejection of EPA's reasons for implementing the 8-hour standard in certain nonattainment areas under subpart 1 in lieu of subpart 2. By limiting the vacatur, the Court let stand EPA's revocation of the 1-hour standard and those anti-backsliding provisions of the Phase 1 Rule that had not been successfully challenged. The June 8th decision affirmed the December 22, 2006, decision that EPA had improperly failed to retain measures required for 1-hour nonattainment areas under the anti-backsliding provisions of the regulations: (1) Nonattainment area New Source Review requirements based on an area's 1-hour nonattainment classification; (2) Section 185 penalty fees for 1-hour severe or extreme nonattainment areas; and (3) measures to be implemented pursuant to section 172(c)(9) or 182(c)(9) of the CAA, on the contingency of an area not making reasonable further progress toward attainment of the 1-hour NAAQS, or for failure to attain that NAAQS. The June 8th decision clarified that the Court's reference to conformity requirements for anti-backsliding purposes was limited to requiring the continued use of 1-hour MVEBs until 8-hour budgets were available for 8-hour conformity determinations, which is already required under EPA's conformity regulations. The Court thus clarified that 1-hour conformity determinations are not required for anti-backsliding purposes.

With respect to the requirement for transportation conformity under the 1-hour standard, the Court in its June 8th decision clarified that for those areas with 1-hour MVEBs in their 1-hour maintenance plans, anti-backsliding requires only that those 1-hour budgets must be used for 8-hour conformity determinations until replaced by 8-hour budgets. To meet this requirement, conformity determinations in such areas must continue to comply with the applicable requirements of EPA's conformity regulations at 40 CFR Part 93. Shelby County, Tennessee has 1-hour budgets and is currently using these budgets to demonstrate transportation conformity until 1997 8-hour budgets are in place.

For the above reasons, and those set forth in the November 19, 2009, proposal for the redesignation of Shelby County, Tennessee, EPA does not believe that the Court's rulings alter any requirements relevant to this redesignation action so as to preclude redesignation, and do not prevent EPA from finalizing this redesignation. EPA believes that the Court's December 22, 2006, and June 8, 2007, decisions impose no impediment to moving forward with redesignation of Shelby County, Tennessee to attainment. Even in light of the Court's decisions, redesignation is appropriate under the relevant redesignation provisions of the Start Printed Page 58CAA and longstanding policies regarding redesignation requests.

II. What Actions Is EPA Taking?

EPA is taking final action to approve Tennessee's redesignation request and to change the legal designation of Shelby County, Tennessee from nonattainment to attainment for the 1997 8-hour ozone NAAQS. The bi-state Memphis 1997 8-hour ozone NAAQS nonattainment area is composed of Shelby County, Tennessee and Crittenden County, Arkansas. The redesignation request, maintenance plan and emission inventory in association with the Arkansas portion of this Area will be addressed through a separate, but coordinated action. In this action, EPA is also approving Tennessee's 1997 8-hour ozone maintenance plan for Shelby County, Tennessee (such approval being one of the CAA criteria for redesignation to attainment status), including the emissions inventory which was submitted pursuant to CAA section 182(a)(1). The maintenance plan is designed to help keep Shelby County, Tennessee (as part of the bi-state Memphis Area) in attainment for the 1997 8-hour ozone NAAQS through 2021. These approval actions are based on EPA's determination that Tennessee has demonstrated that Shelby County, Tennessee has met the criteria for redesignation to attainment specified in the CAA, including a demonstration that the bi-state Memphis Area has attained the 1997 8-hour ozone standard. EPA's analyses of Tennessee's 1997 8-hour ozone redesignation request and maintenance plan are described in detail in the proposed rule published November 19, 2009 (74 FR 59943).

Consistent with the CAA, the maintenance plan that EPA is approving also includes 2006, 2009, 2017, and 2021 MVEBs for NOX and VOC for Shelby County, Tennessee. In this action, EPA is approving these NOX and VOC MVEBs for the purposes of transportation conformity. For regional emission analysis years that involve years prior to 2017, the new 2009 MVEB are the applicable budgets (for the purpose of conducting transportation conformity analyses). For regional emission analysis years that involve years prior to 2021, the new 2017 MVEB are the applicable budgets (for the purpose of conducting transportation conformity analyses). For regional emission analysis years that involve the year 2021 and beyond, the applicable budgets, for the purpose of conducting transportation conformity analyses, are the new 2021 MVEB. In practical terms, the 2006 MVEBs will not be used in Shelby County, Tennessee because this action is being taken in 2009, and there are MVEBs being established for the year 2009 which are required to be used.

III. Why Is EPA Taking These Actions?

EPA has determined that the bi-state Memphis Area has attained the 1997 8-hour ozone standard and has also determined that Tennessee has demonstrated that all other criteria for the redesignation of Shelby County, Tennessee (as part of the bi-state Memphis Area) from nonattainment to attainment of the 1997 8-hour ozone NAAQS have been met. See, section 107(d)(3)(E) of the CAA. EPA is also taking final action to approve the maintenance plan for Shelby County, Tennessee as meeting the requirements of sections 175A and 107(d) of the CAA, and the emissions inventory as meeting the requirements of section 182(a)(1) of the CAA. Furthermore, EPA is approving the new NOX and VOC MVEBs for the years 2006, 2009, 2017, and 2021 contained in Tennessee's maintenance plan for Shelby County because these MVEBs are consistent with maintenance for the bi-state Memphis Area. In the November 19, 2009, proposal to redesignate Shelby County, Tennessee (as part of the bi-state Memphis Area), EPA described the applicable criteria for redesignation to attainment and its analysis of how those criteria have been met. The rationale for EPA's findings and actions is set forth in the proposed rulemaking and summarized in this final rulemaking.

IV. What Are the Effects of These Actions?

Approval of the redesignation request changes the legal designation of Shelby County, Tennessee (as part of the bi-state Memphis Area) from nonattainment to attainment for the 1997 8-hour ozone NAAQS, found at 40 CFR part 81. The approval also incorporates into the Tennessee SIP a plan for maintaining the 1997 8-hour ozone NAAQS in the bi-state Memphis Area through 2021. The maintenance plan includes contingency measures to remedy future violations of the 1997 8-hour ozone NAAQS, and establishes NOX and VOC MVEBs for the years 2006, 2009, 2017, and 2021 for Shelby County, Tennessee. Additionally, this action approves the emissions inventory for this area pursuant to section 182(a)(1) of the CAA. The other portion of the bi-state Memphis Area is Crittenden County, Arkansas. EPA is taking action on Arkansas' redesignation request for Crittenden County Arkansas (as part of the bi-state Memphis area) and the associated emissions inventory and maintenance plan through a separate rulemaking action.

V. Final Action

After evaluating Tennessee's redesignation request, EPA is taking final action to approve the redesignation and change the legal designation of Shelby County, Tennessee (as part of the bi-state Memphis Area) from nonattainment to attainment for the 1997 8-hour ozone NAAQS. EPA is addressing the redesignation request, emission inventory and maintenance plan for Crittenden County, Arkansas (as a portion of the bi-state Memphis Area) in a separate but coordinated action. Through this action, EPA is also approving into the Tennessee SIP, the 1997 8-hour ozone maintenance plan for the Shelby County, Tennessee, which includes the new NOX MVEBs of 55.878 tons per day (tpd) for 2006, 55.620 tpd for 2009, 55.173 tpd for 2017, and 54.445 tpd for 2021; and new VOC MVEBs of 25.216 tpd for 2006, 27.240 tpd for 2009, 18.323 tpd for 2017, and 13.817 tpd for 2021. These new MVEBs were found adequate through a previous action (74 FR 58277). Within 24 months from the effective date of EPA's adequacy finding for the MVEBs, the transportation partners will need to demonstrate conformity to the new NOX and VOC MVEBs pursuant to 40 CFR 93.104(e). Additionally, EPA is approving the emissions inventory for the Shelby County pursuant to section 182(a)(1) of the CAA.

VI. Statutory and Executive Order Reviews

Under the Clean Air Act, the Administrator is required to approve a SIP submission that complies with the provisions of the Act and applicable Federal regulations. 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 Clean Air Act. Accordingly, this action merely approves State law as meeting Federal requirements and does not impose additional requirements beyond those imposed by State law. For that reason, this action:

  • Is not a “significant regulatory action” subject to review by the Office of Management and Budget under Executive Order 12866 (58 FR 51735, October 4, 1993);
  • Does not impose an information collection burden under the provisions of the Paperwork Reduction Act (44 U.S.C. 3501 et seq.);
  • Is certified as not having a significant economic impact on a substantial number of small entities Start Printed Page 59under the Regulatory Flexibility Act (5 U.S.C. 601 et seq.);
  • Does 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);
  • Does not have Federalism implications as specified in Executive Order 13132 (64 FR 43255, August 10, 1999);
  • Is not an economically significant regulatory action based on health or safety risks subject to Executive Order 13045 (62 FR 19885, April 23, 1997);
  • Is not a significant regulatory action subject to Executive Order 13211 (66 FR 28355, May 22, 2001);
  • Is 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 Clean Air Act; and
  • Does not provide EPA with the discretionary authority to address, as appropriate, disproportionate human health or environmental effects, using practicable and legally permissible methods, under Executive Order 12898 (59 FR 7629, February 16, 1994).

In addition, this rule does not have tribal implications as specified by Executive Order 13175 (65 FR 67249, November 9, 2000), because the SIP is not approved to apply in Indian country located in the State, and EPA notes that it will not impose substantial direct costs on 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 Clean Air Act, petitions for judicial review of this action must be filed in the United States Court of Appeals for the appropriate circuit by March 5, 2010. 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).)
