FOR FURTHER INFORMATION CONTACT: Jane Spann of the Air Regulatory Management Section, Air Planning and Implementation Branch, Air, Pesticides and Toxics Management Division, U.S. Environmental Protection Agency, Region 4, 61 Forsyth Street SW., Atlanta, Georgia 30303-8960. Ms. Spann may be reached by telephone at (404) 562-9029 or via electronic mail at [email protected]. SUPPLEMENTARY INFORMATION: I. Background Ozone is created when chemical reactions between volatile organic compounds (VOC) and nitrogen oxides (NOX ) occur in the presence of sunlight. Ozone is reduced by reducing VOC and NOX emissions. The Louisville Metro Air Pollution Control District (LMAPCD) adopted regulation 6.42 Reasonably Available Control Technology Requirements for Major Volatile Organic Compound and Nitrogen Oxides Emitting Facilities on February 2, 1994. LMAPCD's regulation 6.42 was submitted to EPA, through the Commonwealth of Kentucky, on May 21, 1999. On October 23, 2001, EPA approved LMAPCD's regulation 6.42, section 4.4 of which requires LMAPCD to submit each source-specific reasonably available control technology (RACT) determination to EPA for approval into the Kentucky SIP. See 66 FR 53658. On the same date, EPA approved the NOX RACT plan for LG & E's Cane Run Facility into the SIP. See 66 FR 53684. On June 13, 2011, LG & E submitted to the Air Pollution Control Board of Jefferson County (Board) an application for a permit to construct a new NGCC generating unit U15 and auxiliary boiler U16 and retire coal-fired units U4, U5 and U6 at LG & E's Cane Run Facility to comply with other federal requirements, including the Mercury & Air Toxics Standards and the Cross-State Air Pollution Rule.\1\ In response, on July 18, 2012, the Board adopted Amendment 2 establishing NOX emission rates for the new units. On February 13, 2013, KY DAQ, on behalf of LMAPCD, submitted a SIP revision for EPA to approve the LG & E Cane Run Generating Station NOX RACT Plan Amendment 2 into the Kentucky SIP. The LG & E Cane Run Generating Station NOX RACT Plan Amendment 2 includes two parts: Part 1, the existing NOX RACT Plan for the coal-fired units, which will remain in effect until those units are retired; and Part 2, the plan that will become effective upon the start of operation of the NGCC facility and the shut-down of the coal-fired units. --------------------------------------------------------------------------- \1\ Amendment 2 of the February 13, 2013, submittal includes a Dew Point Heater (U17). In 2014, LG&E notified LMAPCD that LG&E is not installing U17 after all. --------------------------------------------------------------------------- II. Analysis of State Submittal CAA section 110(l) does not allow approval of a SIP revision if the revision would interfere with any applicable requirement concerning attainment and reasonable further progress or any other applicable requirement of the CAA. On May 19, 2015, LMAPCD submitted supplemental information regarding the February 13, 2013, submittal to address CAA section 110(l). The May 19, 2015, supplemental document compares the NOX and VOC emissions from the coal-fired electric generation units (EGUs) (U4, U5 and U6) to those from the new NGCC generating unit U15 and auxiliary boiler U16. The comparison shows that substitution of NGCC units for the coal-fired EGUs will cause a reduction of 11,660 tons per year (tpy) of NOX allowable emissions.\2\ It also indicates a possible increase of 25.2 tpy of VOC allowable emissions.\3\ --------------------------------------------------------------------------- \2\ Permitted, maximum, allowable NOX emissions for any consecutive 12 month period. \3\ Permitted, maximum, allowable VOC emissions for any consecutive 12 month period. --------------------------------------------------------------------------- The Louisville area is currently in compliance with the ozone national ambient air quality standards (NAAQS). To demonstrate that the potential VOC increase of 25.2 tpy would not interfere with the area's ongoing attainment of the ozone NAAQS, LMAPCD conducted an analysis of ozone sensitivity based on data from monitors in the Louisville Metropolitan Statistical Area and a region-wide modeling project known as the ``Southeastern Modeling, Analysis, and Planning'' (SEMAP).\4\ The analysis compared the tons per day of ozone reduced based on NOX reductions and based on VOC reductions and determined that NOX emission reductions in the Louisville region are 2 to 16 times more effective than VOC emission reductions at reducing ozone concentrations. Based on this analysis, LMAPCD determined that a 25-ton increase in VOC emissions can be offset with a reduction in NOX emissions of as much as 400 tons to as little as 50 tons. Therefore, LMAPCD concluded that the potential increase in VOC of 25.2 tpy from the Cane Run facility is offset by the concurrent 11,660 tpy reduction in NOX . EPA has preliminarily determined that the new NOX RACT plan associated with Cane Run's change from coal-fired to natural gas-fired units meets the [[Page 39003]] requirements of CAA section 110(l). Thus, EPA is proposing to approve the February 13, 2013, SIP submittal into the federally-approved SIP. This area is, as noted above, in compliance with the ozone NAAQS and there is no indication that this proposed action will cause interference with compliance with the fine particulate matter or nitrogen dioxide NAAQS. --------------------------------------------------------------------------- \4\ Odam, Talat, and Zac Adelman.

Incorporation by Reference In this rule, EPA is proposing to include in a final EPA rule regulatory text that includes incorporation by reference. In accordance with requirements of 1 CFR 51.5, EPA is proposing to incorporate by reference the KY DAQ source-specific provision entitled ``Air Pollution Control Board of Jefferson County Board Order--Amendment 2,'' approved by LMAPCD on July 18, 2012. EPA has made, and will continue to make, these documents generally available electronically through www.regulations.gov and/or in hard copy at the EPA Region 4 office (see the ADDRESSES section of this preamble for more information). IV. Proposed Action EPA is proposing to approve the February 13, 2013, Kentucky SIP revision which adds LG & E Cane Run Generating Station NOX RACT Plan Amendment 2 to the federally-approved Kentucky SIP. This SIP includes emission requirements for the changeover from coal-fired units to natural gas-fired combined cycle EGUs and associated equipment. V. 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. 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, 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 Orders 12866 (58 FR 51735, October 4, 1993) and 13563 (76 FR 3821, January 21, 2011); 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). 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 on tribal governments or preempt tribal law.
