Background Sections 108 and 109 of the CAA govern the establishment, review, and revision, as appropriate, of the NAAQS to protect public health and welfare. The CAA requires periodic review of the air quality criteria—the science upon which the standards are based—and the standards themselves. EPA’s regulatory provisions that govern the NAAQS are found at 40 CFR 50—National Primary and Secondary Ambient Air Quality Standards. In this rulemaking, EPA is proposing to approve changes in PO 00000 Frm 00023 Fmt 4702 Sfmt 4702 32671 Kentucky’s September 9, 2016, submission amending the Commonwealth’s regulations for ambient air quality standards to reflect the historical and current NAAQS, which are found at 401 KAR 53:010. The revision also includes textual changes to language in the regulation to provide regulatory clarity, as well as updating and reformatting the Appendix A table of ambient air quality standards and Appendix A footnotes. The SIP submittal amending Kentucky’s regulations can be found in the docket for this rulemaking at www.regulations.gov and is summarized below. II. EPA’s Analysis of Kentucky’s SIP Revisions The September 9, 2016, SIP submission revises Kentucky regulation 401 KAR 53:010 by updating the Commonwealth’s ambient air quality standards to reflect the historical and current NAAQS for CO, Pb, NO2, ozone, PM10, PM2.5, and SO2; modifying language in the regulation to provide regulatory clarity; and updating and reformatting the Appendix A ambient air quality standards table and Appendix A footnotes. The updates to the air quality standards are discussed in further detail below. a. CO On September 13, 1985, EPA revoked the 1-hour and 8-hour secondary NAAQS for CO. See 50 FR 37484. Accordingly, in the September 9, 2016, SIP submission, Kentucky revised regulation 401 KAR 53:010 to update its air quality standards for CO to be consistent with the NAAQS promulgated by EPA in 1985. b. Pb On November 12, 2008, EPA promulgated a new 1-hour primary and secondary NAAQS for Pb at a level of 0.15 micrograms per cubic meter (mg/ m3), based on a rolling 3-month average. See 73 FR 66964. Accordingly, in the September 9, 2016, SIP submission, Kentucky revised regulation 401 KAR 53:010 to update its air quality standards for Pb to be consistent with the NAAQS promulgated by EPA in 2008. c. NO2 On February 9, 2010, EPA promulgated a new 1-hour primary NAAQS for NO2 at a level of 100 parts per billion (ppb), based on a 3-year average of the 98th percentile of the yearly distribution of 1-hour daily maximum concentrations.

Ozone On July 18, 1997, EPA revoked the 1hour primary and secondary NAAQS for ozone.1 To replace the 1-hour primary and secondary NAAQS for ozone, EPA promulgated a new primary and secondary 8-hour NAAQS for ozone at a level of 0.08 parts per million (ppm), based on an annual fourth-highest maximum 8-hour concentration averaged over three years. See 62 FR 38856. On March 27, 2008, EPA promulgated a new 8-hour primary and secondary NAAQS for ozone at a level of 0.075 ppm, based on an annual fourth-highest maximum 8-hour concentration averaged over three years. See 73 FR 16483. On October 26, 2015, EPA promulgated a new primary and secondary NAAQS for ozone at a level of 0.070 ppm, based on an annual fourth-highest maximum 8-hour concentration averaged over three years. See 80 FR 65292. At that same time, EPA revoked the 1997 8-hour primary and secondary NAAQS for ozone.2 Accordingly, in the September 9, 2016, SIP submission, Kentucky revised regulation 401 KAR 53:010 to update its air quality standards for ozone to be consistent with the NAAQS promulgated by EPA in 1997, 2008, and 2015. e. Particulate Matter (PM10 and PM2.5) On July 18, 1997, EPA promulgated a new 24-hour primary and secondary NAAQS for PM2.5 at a level of 65 mg/m3, based on the 98th percentile of 24-hour PM2.5 concentrations averaged over three years. EPA also promulgated a new annual primary and secondary NAAQS for PM2.5 at a level of 15.0 mg/ m3, based on the annual arithmetic mean averaged over three years. See 62 FR 38652. On October 17 2006, EPA revised the 24-hour primary and secondary PM2.5 NAAQS to 35 mg/m3, based on the 98th percentile of 24-hour PM2.5 concentrations averaged over three years. At that same time, EPA revoked the annual PM10 NAAQS. See 71 FR 61144. On December 14, 2012, EPA revised the primary annual NAAQS for PM2.5 at a level of 12 mg/m3, based on the annual arithmetic mean averaged over three years. See 78 FR 1 EPA revoked the 1-hour ozone standard in all areas in 2005. However, some areas have continuing obligations under the standard. 2 EPA revoked the 1997 8-hour ozone standard in 2015. However, some areas have continuing obligations under the standard. VerDate Sep<11>2014 14:53 Jul 14, 2017 Jkt 241001 3085; January 15, 2013. Accordingly, in the September 9, 2016, SIP submission, Kentucky revised regulation 401 KAR 53:010 to update its air quality standards for PM10 and PM2.5 to be consistent with the NAAQS promulgated by EPA in 1997, 2006, and 2012. f. SO2 On June 22, 2010, EPA promulgated a revised primary SO2 NAAQS to an hourly standard of 75 ppb, based on a 3-year average of the annual 99th percentile of 1-hour daily maximum concentration. At that same time, EPA revoked the 24-hour SO2 NAAQS.3 See 75 FR 35520. Accordingly, in the September 9, 2016, SIP submission, Kentucky revised regulation 401 KAR 53:010 to update its air quality standards for SO2 to be consistent with the NAAQS promulgated by EPA in 2010. III. Incorporation by Reference In this rule, 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 53:010— Ambient air quality standards, effective July 19, 2016. EPA has made, and will continue to make, these documents generally available through www.regulations.gov and/or 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 of Kentucky September 9, 2016, SIP revision identified in section II above, because these changes are consistent with the CAA. 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. Accordingly, this proposed action merely proposes to approve state 3 The 1971 sulfur dioxide standards remain in effect until one (1) year after an area is designated for the 2010 standard, except that in areas designated nonattainment for the 1971 standards, the 1971 standards remain in effect until implementation plans to attain or maintain the 2010 standards are approved, in accordance with 40 CFR part 52, subpart S. PO 00000 Frm 00024 Fmt 4702 Sfmt 4702 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 Orders 12866 (58 FR 51735, October 4, 1993) and 13563 (76 FR 3821, January 21, 2011); • 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.

SUPPLEMENTARY INFORMATION: Throughout this document whenever ‘‘we,’’ ‘‘us,’’ or ‘‘our’’ is used, we mean EPA. This supplementary information section is arranged as follows: I. Background. II. EPA’s Analysis of Minnesota’s Submittal III. What action is EPA taking? IV. Statutory and Executive Order Reviews. I. Background On March 12, 2008, EPA revised the levels of the primary and secondary ozone standards from 0.08 parts per million (ppm) to 0.075 ppm (73 FR 16436). The CAA requires states to submit, within three years after promulgation of a new or revised standard, SIPs meeting the applicable ‘‘infrastructure’’ elements of sections 110(a)(1) and (2). One of these applicable infrastructure elements, CAA section 110(a)(2)(D)(i), requires SIPs to contain ‘‘good neighbor’’ provisions to prohibit certain adverse air quality effects on neighboring states due to interstate transport of pollution. There are four sub-elements within CAA section 110(a)(2)(D)(i). This action addresses the first two sub-elements of the good neighbor provisions, at CAA section 110(a)(2)(D)(i)(I). These subelements require that each SIP for a new or revised standard contain adequate provisions to prohibit any source or other type of emissions activity within the state from emitting air pollutants that will ‘‘contribute significantly to nonattainment’’ or ‘‘interfere with maintenance’’ of the applicable air quality standard in any other state. II. EPA’s Analysis of Minnesota’s Submittals On May 26, 2016, the State of Minnesota submitted a revision to its SIP to address the first two sub-elements PO 00000 Frm 00025 Fmt 4702 Sfmt 4702 32673 of the good neighbor provisions, at CAA section 110(a)(2)(D)(i)(I). Specifically, Minnesota’s submission asserts that the state’s SIP contains adequate provisions to prohibit any source or other type of emissions activity within the state from emitting air pollutants that will ‘‘contribute significantly to nonattainment’’ or ‘‘interfere with maintenance’’ of the 2008 ozone standard in any other state. The SIP submission highlights rules and statutes already in Minnesota’s SIP that limit emissions of nitrogen oxides (NOX) and volatile organic compounds (VOC), the precursor pollutants contributing to ozone formation. Minnesota primarily limits VOC emissions through emission limitations in state-issued part 70 permits. Minnesota has also incorporated by reference EPA’s National Emission Standards for Hazardous Air Pollutants, which further limit VOC emissions. See Minn. R. 7011.7000–9990. Minnesota limits NOX emissions through application of Minn. R. 7011.0500–0553, ‘‘Indirect Heating Fossil Fuel Burning Equipment,’’ as well as Minn. R. 7011.1700–1705, ‘‘Nitric Acid Plants.’’ Additionally, an administrative order issued to the Xcel Energy Sherburne County Generating Station (Sherco) as part of Minnesota’s Regional Haze SIP imposes additional limits on NOX emissions in Minnesota. Finally, Minnesota sources are also subject to a Federal Implementation Plan (FIP) for the Cross-State Air Pollution Rule (CSAPR) at 40 CFR 52.1240, and are required to reduce annual emissions of NOX in support of the 2006 NAAQS for fine particulate matter (PM2.5). EPA developed technical information and a related analysis to assist states with meeting section 110(a)(2)(D)(i)(I) requirements for the 2008 ozone NAAQS, and used this technical analysis to support the CSAPR Update for the 2008 Ozone NAAQS (‘‘CSAPR Update’’).1 As explained below, this analysis supports the conclusion of Minnesota’s analysis regarding interstate transport for the 2008 ozone NAAQS. In the technical analysis supporting the CSAPR Update, EPA used detailed air quality analyses to determine where projected nonattainment or maintenance areas would be and whether emissions from a state would contribute to downwind air quality problems at those projected nonattainment or maintenance receptors. Specifically, EPA determined whether a state’s contributing emissions were at or above a specific threshold (i.e., one percent of the ozone NAAQS). 1 81 E:\FR\FM\17JYP1.SGM FR 74504 (October 26, 2016). 17JYP1

Air Plan Approval; KY; Revisions to Ambient Air Quality Standards

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule.

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

SUMMARY: On September 9, 2016, the Commonwealth of Kentucky, through 
the Kentucky Division for Air Quality (KDAQ), submitted a revision to 
the Kentucky State Implementation Plan (SIP). The Environmental 
Protection Agency (EPA) is proposing to approve changes to the 
Commonwealth's air quality standards for carbon monoxide (CO), lead 
(Pb), nitrogen dioxide (NO2), ozone, particulate matter 
(both PM10 and PM2.5), and sulfur dioxide 
(SO2) to reflect the historical and current National Ambient 
Air Quality Standards (NAAQS). EPA is proposing to approve this SIP 
revision because the Commonwealth has demonstrated that these change 
are consistent with the Clean Air Act (CAA or Act). KDAQ's submission 
also includes additional air quality standards for hydrogen sulfide, 
fluorides, and odor; however, EPA is not proposing to approve these 
state standards into the SIP.

SUPPLEMENTARY INFORMATION: 

I. Background

    Sections 108 and 109 of the CAA govern the establishment, review, 
and revision, as appropriate, of the NAAQS to protect public health and 
welfare. The CAA requires periodic review of the air quality criteria--
the science upon which the standards are based--and the standards 
themselves. EPA's regulatory provisions that govern the NAAQS are found 
at 40 CFR 50--National Primary and Secondary Ambient Air Quality 
Standards. In this rulemaking, EPA is proposing to approve changes in 
Kentucky's September 9, 2016, submission amending the Commonwealth's 
regulations for ambient air quality standards to reflect the historical 
and current NAAQS, which are found at 401 KAR 53:010. The revision also 
includes textual changes to language in the regulation to provide 
regulatory clarity, as well as updating and reformatting the Appendix A 
table of ambient air quality standards and Appendix A footnotes. The 
SIP submittal amending Kentucky's regulations can be found in the 
docket for this rulemaking at www.regulations.gov and is summarized 
below.

II. EPA's Analysis of Kentucky's SIP Revisions

    The September 9, 2016, SIP submission revises Kentucky regulation 
401 KAR 53:010 by updating the Commonwealth's ambient air quality 
standards to reflect the historical and current NAAQS for CO, Pb, 
NO2, ozone, PM10, PM2.5, and 
SO2; modifying language in the regulation to provide 
regulatory clarity; and updating and reformatting the Appendix A 
ambient air quality standards table and Appendix A footnotes. The 
updates to the air quality standards are discussed in further detail 
below.

a. CO

    On September 13, 1985, EPA revoked the 1-hour and 8-hour secondary 
NAAQS for CO. See 50 FR 37484. Accordingly, in the September 9, 2016, 
SIP submission, Kentucky revised regulation 401 KAR 53:010 to update 
its air quality standards for CO to be consistent with the NAAQS 
promulgated by EPA in 1985.

b. Pb

    On November 12, 2008, EPA promulgated a new 1-hour primary and 
secondary NAAQS for Pb at a level of 0.15 micrograms per cubic meter 
([mu]g/m\3\), based on a rolling 3-month average. See 73 FR 66964. 
Accordingly, in the September 9, 2016, SIP submission, Kentucky revised 
regulation 401 KAR 53:010 to update its air quality standards for Pb to 
be consistent with the NAAQS promulgated by EPA in 2008.

c. NO2

    On February 9, 2010, EPA promulgated a new 1-hour primary NAAQS for 
NO2 at a level of 100 parts per billion (ppb), based on a 3-
year average of the 98th percentile of the yearly distribution of 1-
hour daily maximum concentrations. See 75 FR 6474. Accordingly, in the 
September 9,

[[Page 32672]]

2016, SIP submission, Kentucky revised regulation 401 KAR 53:010 to 
update its air quality standards for NO2 to be consistent 
with the NAAQS promulgated by EPA in 2010.

d. Ozone

    On July 18, 1997, EPA revoked the 1-hour primary and secondary 
NAAQS for ozone.\1\ To replace the 1-hour primary and secondary NAAQS 
for ozone, EPA promulgated a new primary and secondary 8-hour NAAQS for 
ozone at a level of 0.08 parts per million (ppm), based on an annual 
fourth-highest maximum 8-hour concentration averaged over three years. 
See 62 FR 38856. On March 27, 2008, EPA promulgated a new 8-hour 
primary and secondary NAAQS for ozone at a level of 0.075 ppm, based on 
an annual fourth-highest maximum 8-hour concentration averaged over 
three years. See 73 FR 16483. On October 26, 2015, EPA promulgated a 
new primary and secondary NAAQS for ozone at a level of 0.070 ppm, 
based on an annual fourth-highest maximum 8-hour concentration averaged 
over three years. See 80 FR 65292. At that same time, EPA revoked the 
1997 8-hour primary and secondary NAAQS for ozone.\2\ Accordingly, in 
the September 9, 2016, SIP submission, Kentucky revised regulation 401 
KAR 53:010 to update its air quality standards for ozone to be 
consistent with the NAAQS promulgated by EPA in 1997, 2008, and 2015.
---------------------------------------------------------------------------

    \1\ EPA revoked the 1-hour ozone standard in all areas in 2005. 
However, some areas have continuing obligations under the standard.
    \2\ EPA revoked the 1997 8-hour ozone standard in 2015. However, 
some areas have continuing obligations under the standard.
---------------------------------------------------------------------------

e. Particulate Matter (PM10 and PM2.5)

    On July 18, 1997, EPA promulgated a new 24-hour primary and 
secondary NAAQS for PM2.5 at a level of 65 [mu]g/m\3\, based 
on the 98th percentile of 24-hour PM2.5 concentrations 
averaged over three years. EPA also promulgated a new annual primary 
and secondary NAAQS for PM2.5 at a level of 15.0 [mu]g/m\3\, 
based on the annual arithmetic mean averaged over three years. See 62 
FR 38652. On October 17 2006, EPA revised the 24-hour primary and 
secondary PM2.5 NAAQS to 35 [mu]g/m\3\, based on the 98th 
percentile of 24-hour PM2.5 concentrations averaged over 
three years. At that same time, EPA revoked the annual PM10 
NAAQS. See 71 FR 61144. On December 14, 2012, EPA revised the primary 
annual NAAQS for PM2.5 at a level of 12 [mu]g/m\3\, based on 
the annual arithmetic mean averaged over three years. See 78 FR 3085; 
January 15, 2013. Accordingly, in the September 9, 2016, SIP 
submission, Kentucky revised regulation 401 KAR 53:010 to update its 
air quality standards for PM10 and PM2.5 to be 
consistent with the NAAQS promulgated by EPA in 1997, 2006, and 2012.

f. SO2

    On June 22, 2010, EPA promulgated a revised primary SO2 
NAAQS to an hourly standard of 75 ppb, based on a 3-year average of the 
annual 99th percentile of 1-hour daily maximum concentration. At that 
same time, EPA revoked the 24-hour SO2 NAAQS.\3\ See 75 FR 
35520. Accordingly, in the September 9, 2016, SIP submission, Kentucky 
revised regulation 401 KAR 53:010 to update its air quality standards 
for SO2 to be consistent with the NAAQS promulgated by EPA 
in 2010.

    \3\ The 1971 sulfur dioxide standards remain in effect until one 
(1) year after an area is designated for the 2010 standard, except 
that in areas designated nonattainment for the 1971 standards, the 
1971 standards remain in effect until implementation plans to attain 
or maintain the 2010 standards are approved, in accordance with 40 
CFR part 52, subpart S.
---------------------------------------------------------------------------

III. Incorporation by Reference

    In this rule, 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 53:010--Ambient air quality 
standards, effective July 19, 2016. EPA has made, and will continue to 
make, these documents generally available through www.regulations.gov 
and/or 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 of Kentucky September 
9, 2016, SIP revision identified in section II above, because these 
changes are consistent with the CAA.

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. Accordingly, this 
proposed 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 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);
     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.
