40 CFR Part 81

[EPA-R04-OAR-2017-0390; FRL-9982-70--Region 4]


Air Plan Approval and Air Quality Designation; KY; Redesignation 
of the Kentucky Portion of the Louisville Unclassifiable Area

AGENCY: Environmental Protection Agency (EPA).

ACTION: Final rule.

-----------------------------------------------------------------------

SUMMARY: On May 4, 2018, the Commonwealth of Kentucky, through the 
Kentucky Energy and Environment Cabinet, Division for Air Quality 
(KDAQ), submitted a request for the Environmental Protection Agency 
(EPA) to redesignate the portion of Kentucky that is within the bi-
state Louisville, KY-IN fine particulate matter (PM2.5) 
unclassifiable area (hereinafter referred to as the ``bi-state 
Louisville Area'' or ``Area'') to unclassifiable/attainment for the 
2012 primary annual PM2.5 national ambient air quality 
standard (NAAQS). The bi-state Louisville Area consists of Jefferson 
County and a portion of Bullitt County in Kentucky, as well as Clark 
and Floyd Counties in Indiana. EPA is approving the State's request and 
redesignating the Area to unclassifiable/attainment for the 2012 
primary annual PM2.5 NAAQS based upon valid, quality-
assured, and certified ambient air monitoring data showing that the 
PM2.5 monitors in the bi-state Louisville Area are in 
compliance with the 2012 primary annual PM2.5 NAAQS.

DATES: This rule will be effective September 19, 2018.

ADDRESSES: EPA has established a docket for this action under Docket 
Identification No. EPA-R04-OAR-2017-0390. All documents in the docket

SUPPLEMENTARY INFORMATION: 

I. Background

    On December 14, 2012, EPA revised the primary annual NAAQS for 
PM2.5 at a level of 12 micrograms per cubic meter ([micro]g/
m\3\), based on a 3-year average of annual mean PM2.5 
concentrations. See 78 FR 3085 (January 15, 2013). EPA established the 
standards based on significant evidence and numerous health studies 
demonstrating that serious health effects are associated with exposures 
to particulate matter.
    The process for designating areas following promulgation of a new 
or revised NAAQS is contained in section

[[Page 42035]]

107(d)(1) of the CAA. On December 18, 2014, EPA designated the majority 
of areas across the country as nonattainment, unclassifiable/
attainment, or unclassifiable\1\ for the 2012 PM2.5 NAAQS 
based upon air quality monitoring data from monitors for calendar years 
2011-2013. See 80 FR 2206 (January 15, 2015). EPA's January 15, 2015, 
rulemaking notice also described a process by which EPA would evaluate 
any complete, quality-assured, certified air quality monitoring data 
from 2014 that a state submitted for consideration before February 27, 
2015. EPA stated that it would evaluate whether, with the inclusion of 
certified 2014 data, the 3-year design value for 2012-2014 suggests 
that a change in the initial designation would be appropriate for an 
area. If EPA agreed that a change in the initial designation would be 
appropriate, EPA would withdraw the designation announced in the 
January 15, 2015, notice for such area before the effective date and 
issue another designation reflecting the inclusion of 2014 data.
---------------------------------------------------------------------------

    \1\ For the initial PM area designations in 2014 (for the 2012 
annual PM2.5 NAAQS), EPA used a designation category of 
``unclassifiable/attainment'' for areas that had monitors showing 
attainment of the standard and were not contributing to nearby 
violations and for areas that did not have monitors but for which 
EPA had reason to believe were likely attaining the standard and not 
contributing to nearby violations. EPA used the category 
``unclassifiable'' for areas in which EPA could not determine, based 
upon available information, whether or not the NAAQS was being met 
and/or EPA had not determined the area to be contributing to nearby 
violations. EPA reserves the ``attainment'' category for when EPA 
redesignates a nonattainment area that has attained the relevant 
NAAQS and has an approved maintenance plan.
---------------------------------------------------------------------------

    In a follow-up designation action published on April 7, 2015 (80 FR 
18535), EPA designated five areas as unclassifiable/attainment in 
Georgia, including two neighboring counties in the bordering states of 
Alabama and South Carolina, that were initially deferred in EPA's 
January 15, 2015, rulemaking. In the same action, EPA changed the 
designations for one area in Ohio, two areas in Pennsylvania, and one 
bi-state area with portions in Kentucky and Ohio from nonattainment to 
unclassifiable/attainment. The bi-state Louisville Area was changed 
from nonattainment to unclassifiable.
    On May 4, 2018, Kentucky submitted a request for EPA to redesignate 
the bi-state Louisville Area to unclassifiable/attainment for the 2012 
primary annual PM2.5 NAAQS now that there is sufficient data 
to determine that the Area is in attainment. In a notice of proposed 
rulemaking (NPRM) published on May 30, 2018 (83 FR 24714), EPA proposed 
to approve the State's request to redesignate the Kentucky portion of 
the bi-state Louisville Area to unclassifiable/attainment for the 2012 
primary annual PM2.5 NAAQS. The details of Kentucky's 
submittal and the rationale for EPA's actions are further explained in 
the NPRM. EPA did not receive any adverse comments on the proposed 
action.

II. Final Action

    EPA is approving Kentucky's redesignation request and redesignating 
the Kentucky portion of the bi-state Louisville Area from 
unclassifiable to unclassifiable/attainment for the 2012 primary annual 
PM2.5 NAAQS.

III. Statutory and Executive Order Reviews

    Under the CAA, redesignation of an area to unclassifiable/
attainment is an action that affects the status of a geographical area 
and does not impose any additional regulatory requirements on sources 
beyond those imposed by state law. A redesignation to unclassifiable/
attainment does not in and of itself create any new requirements. 
Accordingly, this action merely redesignates an area to unclassifiable/
attainment and does not impose additional requirements. For that 
reason, this 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 redesignations 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
     will not have disproportionate human health or 
environmental effects under Executive Order 12898 (59 FR 7629, February 
16, 1994).
    This final redesignation action is not approved to apply to 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.
    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 October 19, 2018. 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. This action may not be challenged later in proceedings to 
enforce its requirements. See section 307(b)(2).
