SUPPLEMENTARY INFORMATION: the portions of this SIP revision that make changes to the District’s Regulation 6.07, Standards of Performance for Existing Indirect Heat Exchangers.3 The March 15, 2018, SIP revision makes minor and ministerial changes to Regulation 6.07 that do not alter the meaning of the regulation or the emissions levels for sources regulated under the Jefferson County Regulations, such as clarifying changes to its applicability. In addition, the changes strengthen the SIP by adding specific test methods and procedures applicable to existing indirect heat exchangers. The SIP revision updates the current SIP-approved version of Regulation 6.07 (version 3) to version 4. The changes to this rule and EPA’s rationale for proposing approval are described in more detail in Section II. II. EPA’s Analysis of the State Submittal As mentioned in Section I of this proposed action, the portion of Jefferson County’s March 15, 2018, SIP revision that EPA is proposing to approve makes changes to Jefferson County Air Quality Regulations at Regulation 6.07, Standards of Performance for Existing Indirect Heat Exchangers. The changes to Section 1, Applicability, and Section 2, Definitions, are intended to provide consistency with other Jefferson County Air Quality Regulations by defining the affected facility within the Definitions section and relying on that definition in the Applicability section. Specifically, Section 1 of the current SIP-approved version of Regulation 6.07 (version 3) provides that this regulation apply to indirect heat exchangers at or above 1 million British thermal units per hour (MMBtu/hr) that ‘‘was in being or under construction before April 19, 1972.’’ The amendments included in the March 15, 2018, SIP revision simplify Section 1, Applicability, to refer to affected facilities ‘‘in being or commenced construction, modification, or reconstruction on or before the applicable classification date defined [in Section 2].’’ I. What action is EPA proposing? EPA is proposing to approve changes to the Jefferson County portion of the Kentucky SIP that were provided to EPA through KDAQ via a letter dated March 15, 2018.1 2 EPA is proposing to approve 1 EPA notes that the Agency received the SIP revision on March 23, 2018. 2 In 2003, the City of Louisville and Jefferson County governments merged and the ‘‘Jefferson County Air Pollution Control District’’ was renamed the ‘‘Louisville Metro Air Pollution Control District.’’ See The History of Air Pollution Control in Louisville, available at https://louisvilleky.gov/ PO 00000 Frm 00016 Fmt 4702 Sfmt 4702 government/air-pollution-control-district/historyair-pollution-control-louisville. However, each of the regulations in the Jefferson County portion of the Kentucky SIP still has the subheading ‘‘Air Pollution Control District of Jefferson County.’’ Thus, to be consistent with the terminology used in the SIP, we refer throughout this notice to regulations contained in the Jefferson County portion of the Kentucky SIP as the ‘‘Jefferson County’’ regulations. 3 EPA notes that the Agency received several submittals revising the Jefferson County portion of the Kentucky SIP transmitted with the same March 15, 2018, cover letter. EPA will be considering action for these other SIP revisions in separate rulemakings. E:\FR\FM\22JYP1.SGM 22JYP1 jbell on DSK3GLQ082PROD with PROPOSALS Federal Register / Vol. 84, No. 140 / Monday, July 22, 2019 / Proposed Rules Section 2 then defines ‘‘Affected facility’’ as those indirect heat exchangers with a capacity of 1 MMBtu/ hr heat input. Therefore, the size of such facilities subject to the Regulation is not changed. Next, the classification date is defined in Section 2 as August 17, 1971 for facilities with a capacity greater than 250 MMBtu/hr heat input, and April 9, 1972 for those with a capacity of 250 MMBtu/hr or less, which correspond to applicability dates for these sizes of sources in Regulation 7.06, Standards of Performance for New Indirect Heat Exchangers. EPA notes that the revised dates are earlier than the current-SIP approved date, however, as Regulation 6.07 regulates sources that would not otherwise be covered under regulations requiring greater emissions reductions (for example, Regulation 7.06 or a relevant NSPS), EPA expects no emissions increases associated with this revision. EPA has preliminarily concluded that the changes to Sections 1 and 2 serve to correct and clarify the existing SIP. Section 3, Standard for Particulate Matter, specifies the applicable emissions standards for particulate matter and opacity, and Section 4, Standard for Sulfur Dioxide, specifies the applicable standards for sulfur dioxide. The changes made to both of these Sections in the March 15, 2018, SIP submittal are minor and ministerial (for example, moving the term particulate matter from subsections to the prefatory text of the corresponding section and moving the allowable sulfur dioxide emissions descriptor from before the equation and including it as a defined term in the equation), and no changes are made to the applicable emissions standards, nor the calculations for determining the standards. Minor and ministerial changes are also made to Table 1, Allowable Particulate Matter Emission Rates, and Table 2, Allowable Sulfur Dioxide Emissions Based on Heat Input Capacity, appended to Regulation 6.07 and corresponding to Sections 3 and 4, respectively. EPA has preliminarily concluded that these changes do not modify the scope or meaning of the provisions. Finally, the March 15, 2018, SIP revision adds Section 5, Test Methods and Procedures, to provide specific instruction on how to determine compliance with the applicable emissions limits for the affected facilities. This section requires compliance with standards for particulate matter and sulfur dioxide be demonstrated using EPA reference methods included in 40 CFR part 60, Appendix A, except as provided in VerDate Sep<11>2014 15:59 Jul 19, 2019 Jkt 247001 Regulation 1.04, Performance Tests. Regulation 1.04 stipulates that if a facility is subject to 40 CFR parts 60, 61, or 63, then specified procedures for test requirements are to be used unless EPA and LMAPCD have agreed upon an alternative or have agreed to a waiver from the applicable test procedures. The addition of section 5 provides specificity in testing requirements for the set of affected facilities under Regulation 6.07 that would not otherwise be subject to 40 CFR part 60 or part 63 (for example, for a source that commenced construction or modification prior to the applicability date for 40 CFR part 60). EPA proposes that the use of federal reference methods is appropriate and sufficient to determine compliance with the applicable standards in Regulation 6.07, and that the inclusion of Section 5 in the SIP is clarifying and SIPstrengthening. As noted above, these rule changes do not relax the emissions reductions to applicable sources, nor do they change any applicable emissions limitations. With respect to the changes related to test methods and procedures, EPA proposes that the changes serve to strengthen the SIP. Therefore, EPA has made the preliminary determination that the aforementioned changes will not have a negative impact on air quality in the area and is therefore proposing to approve version 4 of Regulation 6.07 into the Jefferson County portion of the Kentucky SIP. III. Incorporation by Reference In this document, 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 Jefferson County’s Regulation 6.07, Standards of Performance for Existing Indirect Heat Exchangers, version 4, state effective January 17, 2018. 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 changes to the Jefferson County portion of the Kentucky SIP included in a March 15, 2018, submittal. Specifically, EPA is proposing to approve the District’s Regulation 6.07 version 4 into the SIP. The March 15, 2018, SIP revision makes minor and ministerial changes such as clarifying the applicability of the PO 00000 Frm 00017 Fmt 4702 Sfmt 4702 35053 regulation, and includes more specific requirements for test methods and procedures for affected facilities. EPA believes these changes are consistent with the CAA and EPA policy, and these rule adoptions will not impact the NAAQS or interfere with any other applicable requirement of the Act. 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 E:\FR\FM\22JYP1.SGM 22JYP1 35054 Federal Register / Vol. 84, No. 140 / Monday, July 22, 2019 / Proposed Rules 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: 

I. What action is EPA proposing?

    EPA is proposing to approve changes to the Jefferson County portion 
of the Kentucky SIP that were provided to EPA through KDAQ via a letter 
dated March 15, 2018.1 2 EPA is proposing to approve the 
portions of this SIP revision that make changes to the District's 
Regulation 6.07, Standards of Performance for Existing Indirect Heat 
Exchangers.\3\ The March 15, 2018, SIP revision makes minor and 
ministerial changes to Regulation 6.07 that do not alter the meaning of 
the regulation or the emissions levels for sources regulated under the 
Jefferson County Regulations, such as clarifying changes to its 
applicability. In addition, the changes strengthen the SIP by adding 
specific test methods and procedures applicable to existing indirect 
heat exchangers. The SIP revision updates the current SIP-approved 
version of Regulation 6.07 (version 3) to version 4. The changes to 
this rule and EPA's rationale for proposing approval are described in 
more detail in Section II.
---------------------------------------------------------------------------

    \1\ EPA notes that the Agency received the SIP revision on March 
23, 2018.
    \2\ In 2003, the City of Louisville and Jefferson County 
governments merged and the ``Jefferson County Air Pollution Control 
District'' was renamed the ``Louisville Metro Air Pollution Control 
District.'' See The History of Air Pollution Control in Louisville, 
available at https://louisvilleky.gov/government/air-pollution-control-district/history-air-pollution-control-louisville. However, 
each of the regulations in the Jefferson County portion of the 
Kentucky SIP still has the subheading ``Air Pollution Control 
District of Jefferson County.'' Thus, to be consistent with the 
terminology used in the SIP, we refer throughout this notice to 
regulations contained in the Jefferson County portion of the 
Kentucky SIP as the ``Jefferson County'' regulations.
    \3\ EPA notes that the Agency received several submittals 
revising the Jefferson County portion of the Kentucky SIP 
transmitted with the same March 15, 2018, cover letter. EPA will be 
considering action for these other SIP revisions in separate 
rulemakings.
---------------------------------------------------------------------------

II. EPA's Analysis of the State Submittal

    As mentioned in Section I of this proposed action, the portion of 
Jefferson County's March 15, 2018, SIP revision that EPA is proposing 
to approve makes changes to Jefferson County Air Quality Regulations at 
Regulation 6.07, Standards of Performance for Existing Indirect Heat 
Exchangers.
    The changes to Section 1, Applicability, and Section 2, 
Definitions, are intended to provide consistency with other Jefferson 
County Air Quality Regulations by defining the affected facility within 
the Definitions section and relying on that definition in the 
Applicability section. Specifically, Section 1 of the current SIP-
approved version of Regulation 6.07 (version 3) provides that this 
regulation apply to indirect heat exchangers at or above 1 million 
British thermal units per hour (MMBtu/hr) that ``was in being or under 
construction before April 19, 1972.'' The amendments included in the 
March 15, 2018, SIP revision simplify Section 1, Applicability, to 
refer to affected facilities ``in being or commenced construction, 
modification, or reconstruction on or before the applicable 
classification date defined [in Section 2].''

[[Page 35053]]

    Section 2 then defines ``Affected facility'' as those indirect heat 
exchangers with a capacity of 1 MMBtu/hr heat input. Therefore, the 
size of such facilities subject to the Regulation is not changed. Next, 
the classification date is defined in Section 2 as August 17, 1971 for 
facilities with a capacity greater than 250 MMBtu/hr heat input, and 
April 9, 1972 for those with a capacity of 250 MMBtu/hr or less, which 
correspond to applicability dates for these sizes of sources in 
Regulation 7.06, Standards of Performance for New Indirect Heat 
Exchangers. EPA notes that the revised dates are earlier than the 
current-SIP approved date, however, as Regulation 6.07 regulates 
sources that would not otherwise be covered under regulations requiring 
greater emissions reductions (for example, Regulation 7.06 or a 
relevant NSPS), EPA expects no emissions increases associated with this 
revision. EPA has preliminarily concluded that the changes to Sections 
1 and 2 serve to correct and clarify the existing SIP.
    Section 3, Standard for Particulate Matter, specifies the 
applicable emissions standards for particulate matter and opacity, and 
Section 4, Standard for Sulfur Dioxide, specifies the applicable 
standards for sulfur dioxide. The changes made to both of these 
Sections in the March 15, 2018, SIP submittal are minor and ministerial 
(for example, moving the term particulate matter from subsections to 
the prefatory text of the corresponding section and moving the 
allowable sulfur dioxide emissions descriptor from before the equation 
and including it as a defined term in the equation), and no changes are 
made to the applicable emissions standards, nor the calculations for 
determining the standards. Minor and ministerial changes are also made 
to Table 1, Allowable Particulate Matter Emission Rates, and Table 2, 
Allowable Sulfur Dioxide Emissions Based on Heat Input Capacity, 
appended to Regulation 6.07 and corresponding to Sections 3 and 4, 
respectively. EPA has preliminarily concluded that these changes do not 
modify the scope or meaning of the provisions.
    Finally, the March 15, 2018, SIP revision adds Section 5, Test 
Methods and Procedures, to provide specific instruction on how to 
determine compliance with the applicable emissions limits for the 
affected facilities. This section requires compliance with standards 
for particulate matter and sulfur dioxide be demonstrated using EPA 
reference methods included in 40 CFR part 60, Appendix A, except as 
provided in Regulation 1.04, Performance Tests. Regulation 1.04 
stipulates that if a facility is subject to 40 CFR parts 60, 61, or 63, 
then specified procedures for test requirements are to be used unless 
EPA and LMAPCD have agreed upon an alternative or have agreed to a 
waiver from the applicable test procedures. The addition of section 5 
provides specificity in testing requirements for the set of affected 
facilities under Regulation 6.07 that would not otherwise be subject to 
40 CFR part 60 or part 63 (for example, for a source that commenced 
construction or modification prior to the applicability date for 40 CFR 
part 60). EPA proposes that the use of federal reference methods is 
appropriate and sufficient to determine compliance with the applicable 
standards in Regulation 6.07, and that the inclusion of Section 5 in 
the SIP is clarifying and SIP-strengthening.
    As noted above, these rule changes do not relax the emissions 
reductions to applicable sources, nor do they change any applicable 
emissions limitations. With respect to the changes related to test 
methods and procedures, EPA proposes that the changes serve to 
strengthen the SIP. Therefore, EPA has made the preliminary 
determination that the aforementioned changes will not have a negative 
impact on air quality in the area and is therefore proposing to approve 
version 4 of Regulation 6.07 into the Jefferson County portion of the 
Kentucky SIP.

III. Incorporation by Reference

    In this document, 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 Jefferson County's Regulation 6.07, Standards of Performance 
for Existing Indirect Heat Exchangers, version 4, state effective 
January 17, 2018. 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 changes to the Jefferson County portion 
of the Kentucky SIP included in a March 15, 2018, submittal. 
Specifically, EPA is proposing to approve the District's Regulation 
6.07 version 4 into the SIP. The March 15, 2018, SIP revision makes 
minor and ministerial changes such as clarifying the applicability of 
the regulation, and includes more specific requirements for test 
methods and procedures for affected facilities. EPA believes these 
changes are consistent with the CAA and EPA policy, and these rule 
adoptions will not impact the NAAQS or interfere with any other 
applicable requirement of the Act.

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.
