    AGENCY:

    Environmental Protection Agency (EPA).

    ACTION:

    Proposed rule.

    SUMMARY:

    The Environmental Protection Agency (EPA) is proposing to approve a State Implementation Plan (SIP) revision submitted by the Commonwealth of Kentucky, through the Kentucky Division for Air Quality (KDAQ), on December 9, 2019. The SIP revision updates the description and attainment status designations of geographic areas within the Commonwealth for several National Ambient Air Quality Standards (NAAQS or standards). The updates are being made to conform Kentucky's attainment status tables with the federal attainment status designations for these areas. EPA is proposing to approve Kentucky's SIP revision because it is consistent with the Clean Air Act (CAA or Act) and EPA's regulations.

    SUPPLEMENTARY INFORMATION:

    I. Background

    Sections 108 and 109 of the CAA require EPA to set NAAQS for criteria air pollutants (ozone (O3), particulate matter (PM), carbon monoxide, lead, sulfur dioxide (SO2), and nitrogen dioxide) and to undertake periodic review of these standards. After EPA sets a new NAAQS or revises an existing standard, the CAA requires EPA to determine if areas of the country meet the new standards and to designate areas as either nonattainment, attainment, or unclassifiable.[1] Such designations inform the state's planning and implementation of requirements to achieve and maintain the NAAQS for each area within that state.

    Section 107(d) of the CAA governs the process for these initial area designations. Under this process, states and tribes submit recommendations to EPA as to whether or not an area is attaining the NAAQS for criteria air pollutants. EPA then considers these recommendations as part of its obligation to promulgate the area designations for the new or revised NAAQS. EPA codifies its designations for areas within each state in 40 CFR part 81.[2] Under section 107(d) of the CAA, a designation for an area remains in effect until redesignated by EPA.

    EPA is proposing to approve changes to Kentucky rule 401 Kentucky Administrative Regulation (KAR) 51:010, Attainment status designations, which update the description and attainment status designations of geographic areas within the Commonwealth with regard to a number of NAAQS. The Commonwealth of Kentucky last amended 401 KAR 51:010 in 2016.[3] Since that time, EPA promulgated the 2015 8-hour ozone NAAQS and redesignated several areas within the Commonwealth. Kentucky amended 401 KAR 51:010 in 2019 by updating the attainment status designations in Sections 7 through 9 for O3, PM less than 2.5 microns in diameter (PM2.5), and SO2 to conform with EPA's attainment status designations in 40 CFR 81.318. Regulation 401 KAR 51:010 has also been amended by making one minor textual modification to the NECESSITY, FUNCTION, AND CONFORMITY section. The SIP submittal containing the updated Kentucky regulation can be found in the docket at www.regulations.gov and is summarized below.

    II. Analysis of the Kentucky Submittal

    On December 9, 2019, the Commonwealth of Kentucky, through KDAQ, submitted a revision to the Kentucky SIP. EPA is proposing to approve the December 9, 2019, submission which amends and updates the attainment status designations for O3, PM2.5, and SO2.

    The following are the specific changes made to Sections 7 through 9:

    Section 7.—Attainment Status Designations for Ozone (O3)

    Table (4) was added to reflect the attainment status designation and classification of areas in the Commonwealth of Kentucky for the 2015 8-hour primary and secondary O3 NAAQS.

    Section 8.—Attainment Status Designations for PM2.5

    Table (1) was amended to reflect the attainment status designation of areas in the Commonwealth of Kentucky for the 1997 annual primary and secondary PM2.5 NAAQS.

    Table (2) was amended to reflect the attainment status designation of areas for the 2012 annual PM2.5 primary NAAQS.

    Section 9.—Attainment Status Designations for Sulfur Dioxide (SO2)

    Table (2) was amended to reflect the attainment status designation of areas in the Commonwealth of Kentucky for the 2010 primary SO2 NAAQS.[4]

    EPA has reviewed these changes to the Kentucky regulations for attainment status designations and is proposing to find that these changes are consistent with the attainment status designations in 40 CFR 81.318.

    In addition to the change of attainment status designations in Start Printed Page 66296Sections 7 through 9 of 401 KAR 51:010, the SIP submittal includes a minor textual modification to the NECESSITY, FUNCTION, AND CONFORMITY section that changes the word “requires” to “authorizes” in the first sentence.[5]

    III. Incorporation by Reference

    In this notice, 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 Kentucky regulation 401 KAR 51:010, Attainment status designations, state effective November 19, 2019, which was revised to be consistent with the federal attainment status designations for the areas within the Commonwealth. EPA has made, and will continue to make, these materials generally available through www.regulations.gov and at the EPA Region 4 office (please contact the person identified in the FOR FURTHER INFORMATION CONTACT section of this preamble for more information).

    IV. Proposed Action

    EPA is proposing to approve the Commonwealth's December 9, 2019, SIP revision which contains updates to Kentucky regulation 401 KAR 51:010. The revised regulation amends and updates the attainment status designations for O3, PM2.5, and SO2 to conform with EPA's attainment status designations in 40 CFR 81.318. EPA is proposing to approve these changes because they are consistent with the CAA and EPA regulations.

    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. This action merely proposes to approve 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);
    • Is not an Executive Order 13771 (82 FR 9339, February 2, 2017) regulatory action because SIP approvals are exempted under Executive Order 12866;
    • 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.

    Footnotes

    1.  A nonattainment area is an area that does not meet (or that contributes to ambient air quality in a nearby area that does not meet) the NAAQS; an attainment area is an area that meets the NAAQS; and an unclassifiable area is an area that cannot be classified on the basis of available information as meeting or not meeting the NAAQS. See CAA section 107(d)(1)(A).

    5.  The revised sentence reads “KRS 224.10-100(5) authorizes the cabinet to promulgate administrative regulations for the prevention, abatement, and control of air pollution. This administrative regulation designates the status of all areas of the Commonwealth of Kentucky with regard to attainment of the ambient air quality standards.”
