Start Preamble

AGENCY:

Environmental Protection Agency (EPA).

ACTION:

Direct final rule.

SUMMARY:

EPA is approving revisions to the Kentucky State Implementation Plan (SIP) concerning the maintenance plans addressing the 1997 8-hour ozone standard for the following areas: the Kentucky portion of the Huntington—Ashland Area (a portion of Greenup County); Lexington Area (Fayette and Scott Counties); and Edmonson County. These maintenance plans were submitted to EPA on May 27, 2008, by the Commonwealth of Kentucky and ensure the continued attainment of the 1997 8-hour ozone National Ambient Air Quality Standard (NAAQS) through the year 2020. These plans meet the statutory and regulatory requirements, and are consistent with EPA's guidance. EPA is approving the revisions pursuant to section 110 of the Clean Air Act (“CAA” or “Act”). On March 12, 2008, EPA issued a revised ozone standard. The current action, however, is being taken to address requirements under the 1997 ozone standard. Requirements for the Huntington-Ashland, Lexington, and Edmonson County Areas under the 2008 standard will be addressed in the future.

DATES:

This rule is effective on May 26, 2009 without further notice, unless EPA receives adverse comment by April 24, 2009. If EPA receives such comment, EPA will publish a timely withdrawal in the Federal Register informing the public that this rule will not take effect.

I. Background

In accordance with the CAA, the Huntington-Ashland Area [1] , Lexington Area [2] and Edmonson County were designated as nonattainment for the 1-hour ozone NAAQS (effective January 6, 1992, 56 FR 56694).

On November 13, 1992, the Commonwealth of Kentucky submitted a request to redesignate the Lexington Area and Edmonson County to attainment for the 1-hour ozone standard. Subsequently, on November 12, 1993, the Commonwealth of Kentucky submitted a request to redesignate the Huntington-Ashland Area to attainment for the 1-hour ozone standard. At the same time as the redesignation requests, Kentucky submitted the required ozone monitoring data and maintenance plans to ensure that the Areas would remain in attainment for the 1-hour ozone standard for a period of 10 years, consistent with the CAA 175A(a). The maintenance plans submitted by Kentucky followed EPA guidance for limited maintenance areas, which was provided for the 1-hour ozone standard areas that have design values less than 85 percent of the applicable standard. In this case, the applicable standard was the 1-hour ozone standard of 0.12 parts per million (ppm).

EPA approved Kentucky's requests to redesignate the Huntington-Ashland Area (60 FR 33748), Lexington Area (60 FR 47089) and Edmonson County (59 FR 55053) to attainment for the 1-hour ozone standard. The maintenance plan for the Huntington-Ashland Area (a portion of Greenup County) was approved on June 29, 1995, with an effective date of June 29, 1995 (60 FR 33748). The maintenance plan for the Lexington Area was approved on September 11, 1995, with an effective date of November 13, 1995 (60 FR 47089). The 1-hour ozone maintenance plan for Edmonson County was approved on November 3, 1994, with an effective date of January 3, 1995 (59 FR 55053).

On April 30, 2004, EPA designated areas for the 1997 8-hour ozone NAAQS (69 FR 23858), and published the final Phase I Implementation Rule for the 1997 8-hour ozone NAAQS (69 FR 23951) (Phase I Rule). The Huntington-Ashland Area, Lexington Area, and Edmonson County were designated as attainment for the 1997 8-hour ozone standard, effective June 15, 2004. The attainment areas consequently were required to submit 10-year maintenance plans under section 110(a)(1) of the CAA and the Phase I Rule. On May 20, 2005, EPA issued guidance providing information on how a state might fulfill the maintenance plan obligation established by the CAA and the Phase I Rule (Memorandum from Lydia N. Wegman to Air Division Directors, Maintenance Plan Guidance Document for Certain 8-hour Ozone Areas Under Section 110(a)(1) of Clean Air Act, May 20, 2005—hereafter referred to as “Wegman Memorandum”). On December 22, 2006, the United States Court of Appeals for the District of Columbia Circuit issued an opinion that vacated portions of EPA's Phase I Implementation Rule for the 1997 8-hour Ozone Standard. See South Coast Air Quality Management District. v. EPA, 472 F.3d 882 (D.C. Cir. 2006). The Court vacated those portions of the Rule that provided for regulation of the 1997 8-hour ozone nonattainment areas designated under Subpart 1 in lieu of Subpart 2 (of part D of the CAA), among other portions. The Court's decision does not alter any requirements under the Phase I Rule for maintenance plans. Kentucky's May 27, 2008, proposed SIP revision satisfies the section 110(a)(1) CAA requirements for a plan that provides for implementation, maintenance, and enforcement of the 1997 8-hour ozone NAAQS in the Huntington-Ashland, Lexington, and Edmonson County Areas.

II. Analysis of the State's Submittals

On May 27, 2008, the Commonwealth of Kentucky submitted SIP revisions containing 1997 8-hour ozone maintenance plans for the portion of Greenup County in the Huntington-Ashland Area, the Lexington Area, and Edmonson County as required by section 110(a)(1) of the CAA and the provisions of EPA's Phase I Rule (see 40 CFR 51.905(a)(4)). The purpose of these maintenance plans are to ensure continued attainment and maintenance of the 1997 8-hour ozone NAAQS in the Huntington-Ashland Area, Lexington Area, and Edmonson County until 2020.

As required, these plans provide for continued attainment and maintenance of the 1997 8-hour ozone NAAQS in the area for 10 years from the effective date of the area's designation as attainment for the 1997 8-hour ozone NAAQS, and include components illustrating how each area will continue attainment of the 1997 8-hour ozone NAAQS and provides contingency measures. Each of Start Printed Page 12569the section 110(a)(1) plan components is discussed below for each area.

a. Attainment Inventory. Kentucky developed comprehensive inventories of volatile organic compounds (VOC) and nitrogen oxide (NOX) emissions from area, stationary, and mobile sources using 2002 as the base year to demonstrate maintenance of the 1997 8-hour ozone NAAQS for the Huntington-Ashland Area, Lexington Area and Edmonson County. The year 2002 is an appropriate year for Kentucky to base attainment level emissions because states may select any one of the three years on which the 1997 8-hour attainment designation was based (2001, 2002, and 2003). The Commonwealth's submittals contain the detailed inventory data and summaries by source category. Using the 2002 inventory as a base year reflects one of the years used for calculating the air quality design values on which the 1997 8-hour ozone designation decisions were based. 2002 also is one of the years in the 2002-2004 period used to establish baseline visibility levels for the regional haze program.

A further practical reason for selecting 2002 as the base year emission inventory is that section 110(a)(2)(B) of the CAA and the Consolidated Emissions Reporting Rule (67 FR 39602, June 10, 2002) require states to submit emissions inventories for all criteria pollutants and their precursors every three years, on a schedule that includes the emissions year 2002. The due date for the 2002 emissions inventory is established in the Rule as June 2004. In accordance with these requirements, Kentucky compiles a statewide emissions inventory for point sources on an annual basis. On-road mobile emissions of VOC and NOX were estimated using MOBILE 6.2 motor vehicle emissions factor computer model. Non-road mobile emissions data were derived using the U.S. EPA's Non-Road Model.

In projecting data for the attainment year 2020 inventory, Kentucky used several methods to project data from the base year 2002 to the years 2005, 2008, 2011, 2014, 2017 and 2020. These projected inventories were developed using EPA-approved technologies and methodologies. Point source and non-point source projections were derived from the Emissions Growth Analysis System version 4.0 (EGAS 4.0). Non-road mobile projections were derived from EGAS 4.0, as well as from the National Mobile Inventory Model.

The following tables provide VOC and NOX emissions data for the 2002 base attainment year inventory, as well as projected VOC and NOX emission inventory data for 2005, 2008, 2011, 2014, 2017 and 2020.

Table 1—Partial Greenup County Portion of Huntington-Ashland Area VOC and NOX Emissions Inventory

Emissions2002200520082011201420172020
Total VOC (tons per day)3.142.862.692.532.432.362.33
Total NOX (tons per day)2.422.181.951.721.471.291.19

As shown in Table 1 above, the Kentucky portion of the Huntington-Ashland area is projected to decrease total VOC and NOX emissions from the base year of 2002 to the maintenance year of 2020, thus demonstrating continued attainment/maintenance of the 1997 8-hour ozone standard.

Table 2—Lexington Area (Scott and Fayette Counties)

[VOC and NOX Emissions Inventory]

Emissions2002200520082011201420172020
Total VOC (tons per day)50.8947.8748.2347.8948.1248.9350.13
Total NOX (tons per day)39.3332.6629.8525.7721.1517.9715.98

As shown in Table 2 above, the Lexington Area is projected to decrease total NOX emissions from the base year of 2002 to the maintenance year of 2020. Total VOC emissions steadily decrease from the base year of 2002 through 2008, but are then projected to increase by 1.2 tons per day between the years 2017 to the maintenance year of 2020; however, year 2020 emissions are projected as less than the baseline year emission level. Thus, it is demonstrated that the 1997 8-hour ozone standard will continue to be attainment/maintained.

Table 3—Edmonson County VOC and NOX Emissions Inventory

Emissions2002200520082011201420172020
Total VOC (tons per day)2.722.862.892.802.632.402.24
Total NOX (tons per day)1.341.171.090.950.800.680.61

As shown in Table 3 above, Edmonson County is projected to decrease total VOC and NOX emissions from the base year of 2002 to the maintenance year of 2020. VOC emissions increased slightly between the base year of 2002 and 2011; however, this small spike is not anticipated to affect maintenance. Total VOC's are projected to decrease to levels below that of the base year by 2020, thus demonstrating continued maintenance of the 1997 8-hour ozone standard.

As shown in the tables above, Kentucky has demonstrated that the future year emissions will be less than the 2002 base attainment year's emissions for the 1997 8-hour ozone NAAQS. The attainment inventories submitted by Kentucky for these areas are consistent with the criteria discussed in the Wegman Memorandum. EPA finds that the future emissions levels in 2005, 2008, 2011, 2014, 2017, and 2020 are expected to be similar to or less than the emissions levels in 2002. In the event that a future Start Printed Page 125708-hour ozone monitoring reading in theses areas is found to violate the 1997 8-hour ozone standard, the contingency plan section of the maintenance plans includes measures that will be promptly implemented to ensure that each of these areas returns the maintenance of the 1997 8-hour ozone standard. Please see section (d) Contingency Plan, below, for additional information related to the contingency measures.

b. Maintenance Demonstration. The primary purpose of a maintenance plan is to demonstrate how an area will continue to remain in compliance with the 1997 8-hour ozone standard for the 10 year period following the effective date of designation as unclassifiable/attainment. The end projection year for the maintenance plans for the portion of Greenup County in the Huntington-Ashland Area, Lexington Area and Edmonson County was 2020. As discussed in section (a) Attainment Inventory above, Kentucky identified the level of ozone-forming emissions that were consistent with attainment of the NAAQS for ozone in 2002. Kentucky projected VOC and NOX emissions for the years 2005, 2008, 2011, 2014, 2017 and 2020 in the Huntington-Ashland Area, the Lexington Area and Edmonson County; and EPA finds that the future emissions levels in those years are expected to be similar or below the emissions levels in 2002.

Kentucky's SIP revisions also rely on a combination of several air quality measures that will provide for additional 8-hour ozone emissions reductions in the Huntington-Ashland Area, Lexington Area, and Edmonson County. These measures include the potential implementation of the following, among others: (1) Federal motor vehicle control program; (2) fleet turnover of automobiles; (3) federal reformulated gasoline; (4) tier 2 motor vehicle emissions and fuel standards; (5) heavy-duty gasoline and diesel highway vehicles standard; (6) large nonroad diesel engines rule; (7) nonroad spark ignition engines and recreational engines standard; (8) point source emission reductions; (9) reasonably available control measures (RACM); (10) maximum available control technology (MACT); (11) NOX SIP Call; (12) Clean Air Interstate Rule (CAIR) [3] , (13) several control programs to reduce area source emissions from aerosol coatings, architectural and industrial maintenance coatings, and commercial/consumer products and (14) emissions standards for small and large spark-ignition engines, locomotives and land based diesel engines.

c. Ambient Air Quality Monitoring. The Table below shows design values for the Huntington-Ashland Area, Lexington Area and Edmonson County. The ambient ozone monitoring data was collected at sites that were selected with assistance from the EPA and are considered to be representative of the area of highest concentration.

With regard to the monitors, there is a monitor in Greenup County. The Lexington area has two monitors in Fayette County (Ironworks and Newton) and one in Scott County; however, the Scott County monitor was discontinued in 2002. Edmonson County has one monitor. There were no design values exceeding the 1997 0.08 ppm standard and it is anticipated that the monitors will remain at current locations, unless otherwise allowed to be removed in the consultation with the EPA and in accordance with the 40 CFR part 58.

Table 4—Design Values for 8-Hour Ozone (PPM)

2006-20070.0780.067*0.076
* Monitor discontinued in 2005.

Based on the Table above, each of the available design values indentified is considered to be in attainment of the 1997 ozone NAAQS and demonstrates that the Kentucky areas subject to this action are expected to continue attainment of the 1997 ozone NAAQS. In the event that a design value at one of the Kentucky area monitoring sites exceeds the 1997 ozone standard of 84 parts per billion, the Contingency Plan included in the Kentucky's maintenance plan submittal includes contingency measures which will be promptly implemented in section (d) Contingency Plan, below.

d. Contingency Plan. The section 110(a)(1) maintenance plans include contingency provisions to promptly correct any violation of the 1997 ozone NAAQS that occurs. The contingency indicator for the Huntington-Ashland Area, Lexington Area and Edmonson County, maintenance plans is based on updates to the emission inventories. The triggering mechanism for activation of contingency measures is a ten percent or greater increase in emissions of either VOC or NOX based on the 2002 emissions inventory. In these maintenance plans, if contingency measures are triggered, Kentucky is committing to implement the measures as expeditiously as practicable, but no longer than nine months following the trigger. Some of the contingency measures include: (1) Implementation of a program to require additional emissions reductions on stationary sources; (2) requirement of stage I vapor recovery; (3) requirement of stage II vapor recovery; (4) further restrictions on open burning during summer ozone season; (5) restriction of certain roads or lanes to, or construction of such roads or lanes for use by, passenger buses or high-occupancy vehicles; (6) trip-reduction ordinances; (7) employer based transportation management plans, including incentives; (8) programs to limit or restrict vehicle use in downtown areas, or other areas of emissions concentration particularly during periods of peak use; and (9) programs for new construction and major reconstructions of paths or tracks for use by pedestrians or by non-motorized vehicles when economically feasible and in the public interest. Start Printed Page 12571

These contingency measures and schedules for implementation satisfy EPA's guidance on the requirements of section 110(a)(1) of continued attainment. Continued attainment of the 1997 8-hour ozone NAAQS in the partial area of Greenup County in Huntington-Ashland Area, Lexington Area and Edmonson County will depend, in part, on the air quality measures discussed previously (see section II). In addition, Kentucky commits to verifying the 1997 8-hour ozone status in each maintenance plan through annual and periodic evaluations of the emissions inventories. In the annual evaluations, Kentucky will review VOC and NOX emission data from stationary point sources. During the periodic evaluations (every three years), Kentucky will update the emissions inventory for all emissions source categories, and compare the updated emissions inventory data to the projected 2005, 2008, 2011, 2014, 2017 and 2020 attainment emissions inventories to verify continued attainment of the 8-hour ozone standard.

III. Final Action

Pursuant to section 110 of the Act, EPA is approving the maintenance plans addressing the 1997 8-hour ozone standard for a portion of Greenup County in the Huntington-Ashland Area, the Lexington Area, and Edmonson County, which were submitted by Kentucky on May 27, 2008, and ensure continued attainment of the 1997 8-hour ozone NAAQS through the year 2020. EPA has evaluated the Commonwealth's submittals and has determined that they meet the applicable requirements of the CAA and EPA regulations, and are consistent with EPA policy.

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 May 26, 2009 without further notice unless the Agency receives adverse comment by April 24, 2009. 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 May 26, 2009 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 Kentucky 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 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 May 26, 2009. 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. Parties with objections to this direct final rule are encouraged to file a comment in response to the parallel notice of proposed rulemaking for this action published in the proposed rules section of today's Federal Register, rather than file an immediate petition for judicial review of this direct final rule, so that EPA can withdraw this direct final rule and address the comment in the proposed rulemaking. This action may not be challenged later in proceedings to enforce its requirements. (See section 307(b)(2).)
