Approval and Promulgation of Implementation Plans; Kentucky; Louisville; Fine Particulate Matter 2002 Base Year Emissions Inventory

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule.

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

SUMMARY: EPA is proposing to approve the fine particulate matter (PM2.5) 2002 base year emissions inventory, portion of the State Implementation Plan (SIP) revision submitted by the Commonwealth of Kentucky on December 3, 2008. The emissions inventory is part of the Kentucky's December 3, 2008, SIP revision that was submitted to meet the nonattainment requirements related to the Commonwealth's portion of the bi-state Louisville, KY-IN nonattainment area for the 1997 annual PM2.5 national ambient air quality standards (NAAQS). The bi-state Louisville, KY-IN nonattainment area is comprised of Clark and Floyd Counties in Indiana, in their entireties; the Madison Township portion of Jefferson County, Indiana; and Bullitt and Jefferson Counties in Kentucky, in their entireties. This proposed action only relates to the Kentucky portion (i.e., Bullitt and Jefferson Counties) of this Area. EPA will consider action on the emissions inventory for the Indiana portion of this Area in a separate action. This action is being taken pursuant to section 110 of the Clean Air Act.

1. Background

   On July 18, 1997 (62 FR 36852), EPA established an annual PM2.5 NAAQS at 15.0 micrograms per cubic meter based on a 3-

   year average of annual mean PM2.5 concentrations. On January 5, 2005 (70 FR 944), EPA published its air quality designations and classifications for the 1997 annual PM2.5 NAAQS based upon air quality monitoring data for calendar years 2001-2003. These designations became effective on April 5, 2005. The bi-state Louisville Area (which is comprised of Clark and Floyd Counties in Indiana, in their entireties; the Madison Township portion of Jefferson County, Indiana; and Bullitt and Jefferson Counties in Kentucky in their entireties) was designated nonattainment for the 1997 annual PM2.5 NAAQS. See 40 CFR 81.318 for Kentucky and 40 CFR 81.315 for Indiana.

   Designation of an area as nonattainment starts the process for a state to develop and submit to EPA a SIP under title I, part D of the Clean Air Act (CAA or Act). This SIP 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 to EPA. For the 1997 PM2.5 NAAQS, these SIPs were due April 5, 2008. See 40 CFR 51.1002(a).

   On December 3, 2008, Kentucky 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 PM2.5 NAAQS in the Commonwealth's portion of the bi-state Louisville Area. Subsequently, on March 9, 2011 (76 FR 12860), EPA determined that the bi-state Louisville Area attained the 1997 annual average PM2.5 NAAQS. The determination of attainment was based upon complete, quality-assured and certified ambient air monitoring data for the 2007-

   2009 period, showing that the Area had monitored attainment of the 1997 annual PM2.5 NAAQS. 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 were suspended as a result of the determination of attainment, so long as the Area continues to attain the 1997 annual PM2.5 NAAQS. See 40 CFR 51.1004(c).

   On September 30, 2011, Kentucky withdrew the nonattainment submissions (everything with the exception of the 2002 base year emissions inventory) for its portion of the bi-state Louisville Area as allowed by 40 CFR 51.1004(c). EPA notes that the determination of attainment did not suspend the emissions inventory requirement found in CAA section 172(c)(3), and as such, Kentucky did not withdraw this portion of its December 3, 2008, SIP revision. Section 172(c)(3) of the CAA requires submission and approval of a comprehensive, accurate, and current inventory of actual emissions. EPA is now proposing to approve the emissions inventory portion of the SIP revision submitted by the Commonwealth of Kentucky on December 3, 2008, as required by section 172(c)(3).

2. Analysis of the Commonwealth's Submittal

   As discussed above, section 172(c)(3) of the CAA requires areas to submit a comprehensive, accurate and current inventory of actual emissions from all sources of the relevant pollutant or pollutants in such area. Kentucky selected 2002 as base year for the emissions inventory per 40 CFR 51.1008(b). Emissions contained in Kentucky's December 3, 2008, SIP revision cover the general source categories of point sources, non-road mobile sources, area sources, on-road mobile sources, and biogenic sources. A detailed discussion of the emissions inventory development can be found in Appendix H of the Kentucky submittal; a summary is provided below.

   The table below provides a summary of the annual 2002 emissions of nitrogen oxides (NOX), sulfur dioxide (SO2) and PM2.5 included in the Kentucky submittal.

   The 172(c)(3) emissions inventory is 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, area, nonroad mobile and on-road mobile). This inventory often forms the basis of data that are updated with more recent information and data that also is used in their attainment demonstration modeling inventory. Such was the case in the development of the 2002 emissions inventory that was submitted in the Commonwealth's attainment SIP for its portion of the bi-state Louisville Area. The 2002 emissions inventory was based on data developed with the Visibility Improvement State and Tribal Association of the Southeast (VISTAS) contractors and submitted by the states to the 2002 National Emissions Inventory. Several iterations of the 2002 inventories were developed for the different emissions 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. The data were developed according to current EPA emissions inventory guidance ``Emissions Inventory Guidance for Implementation of Ozone and Particulate Matter National Ambient Air Quality Standards (NAAQS) and Regional Haze Regulations'' (August 2005) and a quality assurance project plan that was developed through VISTAS and approved by EPA. EPA preliminarily 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 Kentucky's emissions inventory and has preliminarily determined that it is adequate for the purposes of meeting section 172(c)(3) emissions inventory requirement. Further, EPA has made the preliminary determination that the emissions were developed consistent with the CAA, implementing regulations and EPA guidance for emission inventories.

3. Proposed Action

   EPA is proposing to approve the 2002 base year emissions inventory portion of the SIP revision submitted by the Commonwealth of Kentucky on December 3, 2008. EPA has made the preliminary determination that this action is consistent with section 110 of the CAA.

4. 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 proposed 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 proposed 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

   Page 31265

   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 F43255, 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 proposed 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 Commonwealth, and EPA notes that it will not impose substantial direct costs on tribal governments or preempt tribal law.
