AGENCY:

Environmental Protection Agency (EPA).

ACTION:

Proposed rule.

SUMMARY:

EPA is proposing to approve a revision to Kentucky's State Implementation Plan (SIP), submitted by the Kentucky Energy and Environment Cabinet, through the Kentucky Division of Air Quality (KDAQ) to EPA on February 5, 2010. The proposed revision modifies Kentucky's prevention of significant deterioration (PSD) and nonattainment new source review (NNSR) permitting regulations in the SIP to address permit requirements promulgated in the 1997 8-Hour Ozone National Ambient Air Quality Standards (NAAQS) Implementation Rule—Phase 2 (hereafter referred to as the “Ozone Implementation NSR Update”). The Ozone Implementation NSR Update revised permit requirements relating to the implementation of the 1997 8-hour ozone NAAQS specifically incorporating nitrogen oxides (NOX) as a precursor to ozone. The proposed revision also includes provisions addressing permit requirements promulgated by EPA on May 1, 2007, which exclude from the NSR major source permitting requirements “chemical process plants” that produce ethanol through a natural fermentation process (hereafter referred to as the “Ethanol Rule”.)

I. What Action Is EPA Proposing Today?

The Commonwealth of Kentucky, through KDAQ, submitted a revision on February 5, 2010, to the Kentucky SIP which relates to Kentucky's Air Quality Regulations, Chapter 51—401 KAR 51:001 “Definitions for 401 KAR Chapter 51,” 401 KAR 51:017 “Prevention of Significant Deterioration of Air Quality,” and 401 KAR 51:052 “Review of New Sources in or Impacting upon Nonattainment Areas.” The SIP revision addresses the Ozone Implementation NSR Update requirements for Kentucky to include NOX as an ozone precursor for permitting purposes. Specifically, the Ozone Implementation NSR Update requirements included changes to major source thresholds for sources in certain classes of nonattainment areas, changes to offset ratios for marginal, moderate, serious, severe, and extreme ozone nonattainment areas, provisions addressing offset requirements for facilities that shut down or curtail operation, and a requirement stating that NOX emissions are ozone precursors. The proposed revision also includes provisions for excluding “chemical process plants” that produce ethanol through a natural fermentation process from the NSR major source permitting requirements. Pursuant to section 110 of the Clean Air Act (CAA or Act), EPA is proposing to approve these revisions into the Kentucky SIP.

Additionally, the rule revision provided in Kentucky's February 5, 2010, submittal updates Kentucky's PSD and NSR permitting regulations to make them consistent with changes to the Federal regulations by removing the existing standards and requirements for clean units (CU) and pollution control projects (PCP). However, EPA is not taking action on the Kentucky rule updates regarding CU and PCP because these portions of Kentucky's rule are specifically not approved into Kentucky's federally-approved SIP.

II. What Is the Background for the Action That EPA Is Proposing To Take Today?

On July 18, 1997, EPA promulgated a revised 8-hour ozone NAAQS of 0.08 parts per million—also referred to as the 1997 8-hour ozone NAAQS. On April 30, 2004, EPA designated areas as attainment, nonattainment and unclassifiable for the 1997 8-hour ozone NAAQS. As part of the 2004 designations, EPA also promulgated an implementation rule for the 1997 8-hour ozone NAAQS in two phases. Phase 1 of EPA's 1997 8-hour ozone implementation rule (Phase 1 Rule), published on April 30, 2004, effective on June 15, 2004, provided the implementation requirements for designating areas under subpart 1 and subpart 2 of the CAA (69 FR 23857).

On November 29, 2005, EPA promulgated the second phase for implementation provisions related to the 1997 8-hour ozone standards—also known as the Phase 2 Rule (70 FR 71612). The Phase 2 Rule addressed control and planning requirements as they applied to areas designated nonattainment for the 1997 8-hour ozone NAAQS such as reasonably available control technology, reasonably available control measures, reasonable further progress, modeling and attainment demonstrations and NSR, and the impact to reformulated gas for Start Printed Page 16390the 1997 8-hour ozone NAAQS transition. Specific to this rulemaking, the Phase 2 Rule made changes to Federal regulations 40 CFR 51.165 and 51.166, which govern the NNSR and PSD permitting programs. Pursuant to these changes, states were required to submit SIP revisions incorporating NOX as an ozone precursor by no later than June 15, 2007. Kentucky's February 5, 2010, SIP submission (the subject of this action) addresses the state requirement to adopt provisions to include NOX as a precursor for ozone for PSD and NNSR permitting purposes.

In addition, on May 1, 2007, EPA promulgated revisions to the PSD and NNSR regulations to address applicability of permitting requirements for “chemical process plants” (72 FR 24059). The revisions to 40 CFR 51.165, 51.166, 52.21, and Appendix S, define “chemical process plants” under the regulatory definition of “major stationary source” to exclude ethanol manufacturing facilities that produce ethanol by natural fermentation processes. Kentucky's February 5, 2010, SIP submission addresses these minimum program elements of the PSD and NNSR programs for “chemical processing plants.”

III. What Is EPA's Analysis of Kentucky's SIP Revision?

On February 5, 2010, the Commonwealth of Kentucky submitted a revision to EPA for approval which revised the Commonwealth's permitting provisions to adopt EPA's Federal regulations specified in the Ozone Implementation NSR Update relating to the incorporation of NOX as an ozone precursor and to address permitting requirements specified in EPA's Ethanol Rule. Specifically, the revision relates to Kentucky's Air Quality Regulations, Chapter 51—401 KAR 51:001 “Definitions for 401 KAR Chapter 51,” 401 KAR 51:017 “Prevention of Significant Deterioration of Air Quality,” and 401 KAR 51:052 “Review of New Sources in or Impacting upon Nonattainment Areas.” The revision became state-effective on February 5, 2010. The submittal revised Kentucky's PSD and NNSR permit programs to make them consistent with changes to the Federal regulations set forth in the Ozone Implementation NSR Update. These changes include changes to major source thresholds for sources in certain classes of nonattainment areas, changes to offset ratios for marginal, moderate, serious, severe, and extreme ozone nonattainment areas, provisions addressing offset requirements for facilities that shut down or curtail operation, and a requirement stating that NOX emissions are ozone precursors. In addition, the submittal revised Kentucky's PSD and NNSR permit programs to make them consistent with changes to the Federal regulations set forth in EPA's Ethanol Rule. These changes include changes to the regulatory definition of “major stationary source” to exclude ethanol manufacturing facilities that produce ethanol by natural fermentation processes. These changes affect both the applicability threshold and whether this industry must count fugitive emissions in determining its major source status.

The revision included in Kentucky's PSD and NNSR programs are substantively the same as the Ozone Implementation NSR Update and the Ethanol Rule. The Kentucky rules have been formatted to conform to Kentucky rule drafting standards (KRS Chapter 13A), but in substantive content the rules are the same as the Federal rules. As part of its review of the Kentucky submittal, EPA performed a line-by-line review of the proposed revisions and has determined that they are consistent with the permit program requirements for NSR, set forth at 40 CFR 51.165 and 51.166.

Kentucky's February 5, 2010, SIP submission providing the PSD and NNSR rule revisions also includes the removal of provisions that were vacated by the United States Court of Appeals for the District of Columbia Circuit.[1] Since EPA did not take action on Kentucky's SIP with regard to the vacated portions (i.e., these provisions were not incorporated into the federally-approved SIP), EPA is not taking action through this rulemaking on the removal of these provisions as provided in Kentucky's February 5, 2010, submittal.

IV. Proposed Action

Pursuant to section 110 of the CAA, EPA is proposing to approve Kentucky's SIP revision, submitted February 5, 2010, which incorporates NOX as an ozone precursor for permitting purposes into the Kentucky SIP, and addresses major source applicability for ethanol manufacturing facilities. EPA is proposing to approve these revisions because they are consistent with the CAA, and EPA regulation and policy.

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. 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, 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.
