Environmental Protection Agency (EPA).
EPA is proposing to approve the State Implementation Plan (SIP) revisions submitted by the Commonwealth of Kentucky on September 12, 2005, and March 24, 2006. The first revision provides Kentucky's response to EPA's regulations entitled, “Finding of Significant Contribution and Rulemaking for Certain States in Ozone Transport Assessment Group Region for Purposes of Reducing Regional Transport of Ozone,” otherwise known as the “Nitrogen Oxides (NOX) SIP Call Phase I.” The second revision responds to EPA's regulations entitled, “Interstate Ozone Transport: Response to Court Decisions on the NOX SIP Call, NOX SIP Call Technical Amendments, and Section 126 Rules,” otherwise known as the “ NOX SIP Call Phase II.” The NOX SIP Call Phase II revision satisfies EPA's rule that requires Kentucky to submit Phase II revisions necessary to achieve applicable, incremental reductions of NOX. The intended effect of the Phase II SIP revision is to reduce emissions of NOX originating in the Commonwealth of Kentucky to help attain and maintain the national ambient air quality standard for ozone. The March 24, 2006, final submittal stopped the federal implementation plan clock that started on February 8, 2006, when EPA made a finding that Kentucky failed to submit the required SIP for Phase II of the NOX SIP Call by April 1, 2005.

II. Analysis of State's Submittal
III. Proposed Action
IV. Statutory and Executive Order Reviews
On October 27, 1998, EPA published a final rule known as the “NOX SIP Call” (63 FR 57356), and later known as the “NOX SIP Call Phase I.” The NOX SIP Call Phase I required 22 states, including the Commonwealth of Kentucky, to meet NOX emission budgets during the ozone season (March through September) to reduce the amount of ground level ozone that is transported across the eastern United States. EPA identified NOX emission reductions by source category when they could be achieved by using cost-effective measures. These source categories include electric generating units (EGUs), non-EGUs, internal combustion engines (ICEs) and cement kilns. For each affected jurisdiction, EPA determined NOX emission budgets based on the implementation of cost effective controls. The budgets were to be met by the year 2007. Phase I of the NOX SIP Call gave states the flexibility to decide which source categories to regulate to meet its statewide budget. During Phase I, Kentucky regulated EGUs, non-EGUs and cement kilns, but chose not to address ICEs. See, 67 FR 17624, 17625 (April 11, 2002) (Approval and Promulgation of Implementation Plans: Kentucky: Nitrogen Oxides Budget and Allowance Trading Program).
A number of parties, including certain states as well as industry and labor groups, challenged Phase I of the NOX SIP Call rule. On March 2, 2000, EPA published additional technical amendments to the NOX SIP Call in the Federal Register (64 FR 26298 and 65 FR 11222, respectively). On March 3, 2000, the United States Court of Appeals for the District of Columbia Circuit Court (D.C. Circuit Court) issued its decision on the NOX SIP Call, ruling in favor of EPA on all the major issues. Michigan v. EPA, 213 F.3d 663 (D.C. Cir. 2000). However, the D.C. Circuit Court remanded four specific elements to EPA for further action: The definition of EGU; the level of control for stationary internal combustion engines; the geographic extent of the NOX SIP Call for Georgia and Missouri; and the inclusion of Wisconsin. On January 31, 2002, the Kentucky Environmental and Public Protection Cabinet (KEPPC) submitted final revisions to its SIP that complied with the requirements of Phase I of the NOX SIP Call. EPA approved the revisions on April 11, 2002, 67 FR 17624, which became effective on June 10, 2002.
On April 21, 2004, EPA published a final rule, addressing the remanded portion of the NOX SIP Call Rule. This rule is entitled, “Interstate Ozone Transport: Response to Court Decisions on the NOX SIP Call, NOX SIP Call Technical Amendments, and Section 126 Rules,” and is otherwise known as the “NOX SIP Rule Phase II” (69 FR 21604). The action promulgated specific changes in response to the Court's ruling on Phase I of the Rule. Specifically, it finalized certain aspects of the definitions of EGU and non-EGU, and the control level assumed for large stationary ICEs. For large, natural gas fired, stationary ICEs the control level was set at 82 percent, because the vast majority of large natural gas-fired ICEs are lean burn. For diesel and dual fuel stationary ICEs the control level was set at 90 percent since on average they are rich burn, diesel and dual fuel ICEs. The April 21, 2004, rule also finalized partial state budgets for Georgia, Missouri, Alabama, and Michigan, changes to statewide NOX budgets, the SIP submittal dates for the required states to address the Phase II portion of the budget, the SIP submittal dates for Georgia and Missouri, the compliance date for all covered sources, and the exclusion of Wisconsin from the NOX SIP Call (69 FR 21604, April 21, 2004). The final rule also required states that submitted NOX SIP Call Phase I revisions, to submit by April 1, 2005, Phase II SIP revisions as needed to achieve the necessary incremental reductions of NOX. Phase II requires emissions reductions that are relatively small, representing less than 10 percent of the total reductions required by Phase I of the NOX SIP Call.
Phase II of the NOX SIP Call required Kentucky to reduce the Phase I NOX emissions originating in the Commonwealth from 165,075 tons (Phase I budget) to 162,519 tons (Phase II budget) of NOX emissions. (69 FR 21604, 2162, April 21, 2004). This represents a 4,224 ton reduction of NOX emissions in Kentucky. The budget numbers for Phase II for each affected state were based on the Phase I emission inventory as revised in the “Technical Amendment to the Finding of Significant Contribution and Rulemaking for Certain States for Purposes of Reducing Regional Transport of Ozone,” which was published on March 2, 2000. However, EPA approved a revised Phase I Budget for Kentucky in a revision to the NOX SIP Call submitted on April 11, 2002 (67 FR 17624). Therefore, the final Kentucky Phase II Budget in the April 21, 2004, notice is inaccurate because it is based on the previous Phase I Budget.
On January 23, 2004, EPA wrote a letter to KEPPC clarifying that based on current rules and regulations, including 63 FR 57356, 57416 (October 27, 1998), and 40 CFR 96.2, EPA was allowing each state with one or more carbon monoxide (CO) boiler combusting CO from fluidized catalytic cracking units (FCCUs) to determine whether all of the Commonwealth's FCCU-CO boilers were covered by the NOX SIP Call trading program. There is currently only one facility in Kentucky with FCCU-CO boilers (the Ashland Oil facility, located in Ashland, Kentucky). Kentucky elected to exclude all FCCU-CO boilers in the Commonwealth from the NOX trading program. Today's action removes the requirement from the Kentucky SIP that such units comply with the NOX SIP Call Phase I by exempting them from the non-EGU portion of the Kentucky NOX budget. However, Kentucky is still able to meet the phase II budgets through other reductions. For more information regarding the specifics of Phase I source categories and budgets, see 67 FR 17624 (April 11, 2002).
Kentucky is achieving the Phase II goal by setting the control level for large, stationary ICEs at 82 percent, and for diesel and dual fuel stationary ICEs at 90 percent. The application of control levels to ICEs represents a reduction in NOX emissions originating in Kentucky. Therefore, the large stationary ICE portion of Kentucky's non-EGU NOX trading budget is being reduced by 2,491 tons of NOX emissions.
On September 12, 2005, the KEPPC submitted a draft of its SIP regulation revisions, intended to meet the requirements of the NOX SIP Call Phase II. A public hearing was conducted on October 21, 2005. On March 24, 2006, Start Printed Page 25688SIP revisions were submitted in their final form. The March 24, 2006, submittal stopped the federal implementation plan clock that started under the Clean Air Act (CAA) following EPA's February 8, 2006, finding that Kentucky failed to submit the required SIP revisions for Phase II of the NOX SIP Call by April 1, 2005 (71 FR 6347, February 8, 2006).
II. Analysis of State Submittal
The September 12, 2005, and March 24, 2006, proposed revisions to the Kentucky SIP include changes to regulation 401 KAR 51:150, which are consistent with EPA requirements for Phase II of the NOX SIP Call. In addition, the proposed revisions included a change to regulation 401 KAR 51:160, which is consistent with EPA requirements for Phase I of the NOX SIP Call. The Phase II revisions require the Cabinet to set NOX emission levels for large stationary ICEs, including large utility and industrial boilers (i.e., engines emitting more than one ton of NOX per average ozone season day in 1997), except FCCU-CO boilers, at 82 percent. The combination of the Kentucky regulations addressing NOX emissions from large utility and industrial boilers, cement kilns and ICEs achieve all the necessary NOX reductions required to meet NOX Phase II requirements for Kentucky. In light of these reductions, the projected 2007 control period NOX emissions for the various categories are as follows in tons per year:
- Total EGU NOX Budget—36,504.
- Total Non-EGU NOX—Budget 26,259.
- Total NOX Budget for Stationary Area Sources—31,807.
- Total NOX Budget for Nonroad Mobile Sources—15,025.
- Total NOX Budget for Highway Mobile Sources—53,268.
- Total NOX Budget for Kentucky—162,863.
The revised non-EGU NOX budget was 28,750 tons in the January 31, 2002, SIP revision and revised to 26,259 tons in the September 2005 SIP Revision. The large boilers/turbines were reduced from 179 to 64 NOX ozone season tons due to FCCU-CO boilers being exempted from that category. The large cement kilns remained the same at 1,091 NOX ozone season tons. The large ICEs went from 3,083 to 577 NOX ozone season tons by applying the appropriate Phase II reductions. Small and other sources increased from 24,397 to 24,527 tons due to moving Ashland Oil from the large boilers/turbines to this portion of the non-EGU budget. Additionally, there was an error in Kentucky's original inventory for units at the Texas Gas-Jeffersontown facility, resulting in eight more units than initially included in the small/other sources budget. The chart below summarizes the budgets:
|Portion of the non-EGU NOX emissions budget||January 31, 2002 NOX SIP Call SIP revision submittal (NOX ozone season tons)||March 24, 2006 NOX SIP Call SIP revision submittal (NOX ozone season tons)|
|Large Cement Kilns||1091||1091|
|Total Non-EGU Emissions||28,750||26,259|
|* Non-EGU budget that is part of the NOX SIP Call cap and trade program.|
III. Proposed Action
EPA is proposing to approve the aforementioned changes to the SIP, including Kentucky's NOX SIP Call Phase II budget. This SIP revision is consistent with section 110 of the CAA.
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 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 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 rule does not have tribal implications as specified by Executive Order 13175 (65 FR 67249, Start Printed Page 25689November 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.Start List of Subjects
