IV. Statutory and Executive Order Reviews

I. Background

On July 18, 1997 (62 FR 36852), EPA established an annual PM_2.5 NAAQS at 15.0 micrograms per cubic meter based on a 3-year average of annual mean PM_2.5 concentrations. On January 5, 2005 (70 FR 944), EPA published its air quality designations and classifications for the 1997 annual PM_2.5 NAAQS based upon air quality monitoring data for calendar years 2001-2003. These designations became effective on April 5, 2005. The Knoxville Area was designated nonattainment for the 1997 annual PM_2.5 NAAQS. See 40 CFR 81.343.

Designation of an area as nonattainment starts the process for a state to develop and submit to EPA a SIP revision under title I, part D of the CAA. This SIP revision must include, among other elements, a demonstration of how the NAAQS will be attained in the nonattainment area as expeditiously as practicable, but no later than the date required by the CAA. Under CAA section 172(b), a state has up to three years after an area's designation as nonattainment to submit its SIP revision to EPA. For the 1997 annual PM_2.5 NAAQS, these submittals were due April 5, 2008. See 40 CFR 51.1002(a).

On April 4, 2008, Tennessee submitted an attainment demonstration and associated reasonably available control measures (RACM), a reasonable further progress (RFP) plan, contingency measures, a 2002 base year emissions inventory and other planning SIP revisions related to attainment of the 1997 annual PM_2.5 NAAQS in the Knoxville Area. Subsequently, on June 6, 2012 (77 FR 33360), EPA proposed that the Knoxville Area has attained the 1997 annual PM_2.5 NAAQS. The proposed determination of attainment is based upon quality-assured and certified ambient air monitoring data for the 2009-2011 period showing that the Area has monitored attainment of the 1997 annual PM_2.5 NAAQS. EPA did not receive any comments on the proposed determination and published the final determination on August 2, 2012 (77 FR 45954). In accordance with the final determination of attainment, the requirements for the Area to submit an attainment demonstration and associated RACM, RFP plan, contingency measures, and other planning SIP revisions related to attainment of the standard are suspended, so long as the Area continues to attain the 1997 annual PM_2.5 NAAQS. See 40 CFR 51.1004(c).

EPA notes that a final determination of attainment would not suspend the emissions inventory requirement found in CAA section 172(c)(3), which requires submission and approval of a comprehensive, accurate, and current inventory of actual emissions. In today's action, EPA is approving the emissions inventory portion of the attainment demonstration SIP revision submitted by Tennessee on April 4, 2008, as required by section 172(c)(3).

II. Analysis of the State's Submittal

As discussed above, section 172(c)(3) of the CAA requires nonattainment areas to submit a comprehensive, accurate and current inventory of actual emissions from all sources of the relevant pollutant or pollutants in such areas. Tennessee selected 2002 as the base year for the emissions inventory per 40 CFR 51.1008(b). Emissions contained in Tennessee's April 4, 2008, SIP revision cover the general source categories of point sources, non-road mobile sources, area sources, and on-road mobile sources of direct and precursor emissions of PM_2.5. The precursor emissions included in the 2002 Knoxville Area emissions inventory include nitrogen oxides (NO_X) and sulfur dioxide (SO₂). A detailed discussion of the emissions inventory development can be found in Appendix H of the Tennessee submittal. The table below provides a summary of the annual 2002 emissions of NO_X, SO₂ and direct PM_2.5 included in the Tennessee submittal.

The 172(c)(3) emissions inventory was developed by the incorporation of data from multiple sources. States were required to develop and submit to EPA a triennial emissions inventory according to the Consolidated Emissions Reporting Rule for all source categories (i.e., point, nonroad mobile, area, and on-road mobile). This inventory often forms the basis of data that are updated with more recent information and data that also are used in the attainment demonstration modeling inventory. Such was the case in the development of the 2002 base year emissions inventory that was submitted in Tennessee's attainment demonstration SIP for the Knoxville Area. The 2002 base year emissions inventory was based on data developed with the Visibility Improvement State and Tribal Association of the Southeast (VISTAS) contractors and submitted by the VISTAS states (i.e., Alabama, Florida, Georgia, Kentucky, Mississippi, North Carolina, South Carolina, Tennessee, Virginia and West Virginia) to the EPA 2002 National Emissions Inventory. Several iterations of the VISTAS 2002 inventories were developed through the VISTAS project for the different emission source categories resulting from revisions and updates to the data. This resulted in the use of version G2 of the updated data to represent the point sources' emissions. Data from many databases, studies and models (e.g., Vehicle Miles Traveled, fuel programs, the NONROAD 2002 model data for commercial marine vessels, locomotives and Clean Air Market Division, etc.) resulted in the inventory submitted in this SIP revision. The VISTAS and Tennessee emissions inventory data were developed according to current EPA emissions inventory guidance titled “Emissions Inventory Guidance for Implementation of Ozone and Particulate Matter National Ambient Air Quality Standards (NAAQS)” (August 2005) and “Clean Air Fine Particle Implementation Rule” (72 FR 20586, April 25, 2007) and a quality assurance project plan that was developed through VISTAS and approved by EPA. EPA agrees that the process used to develop this inventory was adequate to meet the requirements of CAA section 172(c)(3) and the implementing regulations.

EPA has reviewed the 2002 base year emissions inventory from Tennessee and determined that it is adequate for the purposes of meeting section 172(c)(3) emissions inventory requirement. Further, EPA has determined that the emissions were developed consistent with the CAA, implementing regulations and EPA guidance for emissions inventories.

III. Final Action

EPA is taking direct final action to approve the 2002 base year emissions inventory portion of the attainment demonstration SIP revision submitted by the State of Tennessee on April 4, 2008. EPA determined that this action is consistent with section 110 of the CAA.

EPA is publishing this rule without prior proposal because the Agency views this as a non-controversial revision and anticipates no adverse comments. However, in the proposed rules section of this Federal Register publication, EPA is publishing a separate document that will serve as the proposal to approve the SIP revision should adverse comment be filed. This rule will be effective on October 22, 2012 without further notice unless the Agency receives adverse comment by September 20, 2012. If EPA receives such comments, then EPA will publish a document withdrawing the final rule and informing the public that the rule will not take effect. All public comments received will then be addressed in a subsequent final rule based on the proposed rule. EPA will not institute a second comment period on this action. Any parties interested in commenting must do so at this time. If no such comments are received, the public is advised this rule will be effective on October 22, 2012 and no further action will be taken on the proposed rule.

IV. Statutory and Executive Order Reviews

Under the CAA, 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 CAA. 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 under 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 CAA; 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 final 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 CAA, petitions for judicial review of this action must be filed in the United States Court of Appeals for the appropriate circuit by October 22, 2012. 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).
