SUPPLEMENTARY INFORMATION:
I. EPA's Proposed Action
EPA is proposing to approve changes to the Kentucky SIP that were
received by EPA on March 4, 2020 and supplemented on January 28, 2022.
Approval of this submission would incorporate Board Order--Amendment 2,
issued by the Air Pollution Control Board of Jefferson County (Board)
for American Synthetic Rubber Company (ASRC), into the SIP. This
amended Board Order \1\ would replace in the SIP the existing Board
Order issued by the Board for ASRC. The amended Board Order and EPA's
rationale for proposing to approve it into the SIP are described in
detail below.
---------------------------------------------------------------------------
\1\ A Board Order issued by the Board is a regulatory instrument
which specifies air pollution control limits or requirements for a
specific source or company. See 66 FR 53665, 53671 (October 23,
2001) (Response 2I).
---------------------------------------------------------------------------
II. Background and EPA's Analysis of the Proposed Revisions
Three counties in the Louisville area (Jefferson County in Kentucky
and Clark and Floyd Counties in Indiana) were designated as
nonattainment for ozone in March 1978 (43 FR 8962). On November 6, 1991
(56 FR 56694), after the CAA Amendments of 1990 were enacted, Jefferson
County and portions of Bullitt and Oldham Counties in Kentucky and the
Indiana Counties of Clark and Floyd were designated as the Louisville
Moderate ozone nonattainment area (Louisville Area) under section
107(d)(4)(A) as a result of monitored violations of the 1979 1-hour
ozone national ambient air quality standards (NAAQS) during 1987-
1989.\2\
---------------------------------------------------------------------------
\2\ The Louisville Area was subsequently redesignated to
attainment for the 1979 1-hour ozone NAAQS. See 66 FR 53665 (October
23, 2001). More recently, the Louisville Area was designated as
Marginal nonattainment for the 2015 ozone NAAQS. See 83 FR 25776
(June 4, 2018).
---------------------------------------------------------------------------
Section 182(b)(2) of the CAA requires states to adopt RACT for all
major stationary sources of VOC in Moderate and above ozone
nonattainment areas. Section 182(f) of the CAA requires that the same
provisions for major stationary sources of VOC shall also apply to
major stationary sources of NOX. Therefore, pursuant to
section 182(f), RACT is a requirement, with certain exceptions
described therein, for major sources of NOX in ozone
nonattainment areas where VOC RACT applies.
To comply with the NOx RACT requirement, which was a result of the
Moderate nonattainment area designation for the 1-hour ozone NAAQS, the
District submitted Jefferson County Air Quality Regulation 6.42,
Reasonably Available Control Technology Requirements for Major Volatile
Organic Compound- and Nitrogen Oxides-Emitting Facilities, to EPA
approval.\3\ Regulation 6.42 requires the establishment and
implementation of RACT, including the determination and demonstration
of compliance with RACT, for certain emission units located at a major
stationary source of NOX or VOC emissions and requires that
each determination of RACT approved by the District be submitted to EPA
as a source-specific revision to the Kentucky SIP. RACT is defined at
paragraph 1.66 of District Regulation 1.02 as meaning ``devices,
systems, process modifications, or other apparatus or techniques,
including pollution prevention approaches, that are reasonably
available taking into account the necessity of imposing those controls
in order to attain and maintain a national ambient air quality standard
and the social, environmental, and economic impact of those controls.''
---------------------------------------------------------------------------
\3\ EPA incorporated Regulation 6.42 into the Jefferson County
portion of the Kentucky SIP on October 23, 2001. See 66 FR 53658.
---------------------------------------------------------------------------
As discussed in EPA's June 22, 2001 (66 FR 33505), proposal to
redesignate the Louisville Area to attainment for the 1979 1-hour ozone
NAAQS, Regulation 6.42 has been implemented in part by means of Board
Orders adopted by the Air Pollution Control Board of Jefferson County.
Such Board Orders contain NOX RACT and VOC RACT plans, which
set forth RACT requirements for the source, including monitoring,
recordkeeping, and reporting requirements, as attachments.
[[Page 24511]]
ASRC, owned by Michelin North America, Inc., provides electrical
power to its facility by operating two coal-fired boilers and two
natural gas-fired boilers that are subject to the RACT requirements of
Regulation 6.42. The original Board Order for ASRC was approved by the
Board on December 20, 2000, and subsequently submitted to EPA as a
source-specific revision to the Kentucky SIP. The Board Order, approved
by EPA on October 23, 2001 (66 FR 53665), includes as an attachment a
RACT plan which restricts the allowable emissions of NOX
(expressed as NO2) from (coal-fired) Boiler No. 1 and Boiler
No. 2 to 0.50 pound per million British thermal units (lb/MMBtu) of
heat input each, based upon a 30-day rolling average and which applies
at all times. The RACT plan also restricts allowable emissions of
NOX (expressed as NO2) from (natural gas-fired)
Boiler No. 3 and Boiler No. 4 to 0.20 lb/MMBtu of heat input each,
which applies at all times.
On August 1, 2019, ASRC submitted a proposed RACT plan to the
District for three new boilers, referred to as Boilers B5, B6, and B7,
that are planned to be constructed to replace the facility's existing
Boiler Nos. 1, 2, 3, and 4. The Board approved Board Order--Amendment 1
on November 20, 2019. Board Order--Amendment 1 includes as an
attachment a revised RACT plan that addresses RACT for both
NOX and VOC emissions.\4\ On March 4, 2020, the District,
through the Cabinet, submitted a SIP revision to EPA to replace the
existing Board Order for ASRC with Board Order--Amendment 1. On
November 17, 2021, the Board approved Board Order--Amendment 2, which
includes an updated RACT plan.\5\ On January 28, 2022, the District,
through the Cabinet, submitted to EPA a supplement to the March 4,
2020, SIP revision to replace Board Order--Amendment 1 with Board
Order--Amendment 2.
---------------------------------------------------------------------------
\4\ The existing SIP-approved Board Order does not include VOC
RACT requirements.
\5\ Specifically, the RACT plan was updated to include revised
NOX monitoring requirements that are better suited to the
30-day rolling average NOX limit for the new boilers.
---------------------------------------------------------------------------
The revised RACT plan attached to Board Order--Amendment 2 contains
two sections: Section A, which applies to the facility's existing
boilers (Boiler Nos. 1, 2, 3, and 4), and Section B, which applies to
the facility's planned new boilers (B5, B6, and B7). Section A consists
of the same provisions as the original Board Order of December 20,
2000, and includes the same NOX emission limits (summarized
above) for the existing boilers that are currently incorporated into
the SIP. EPA proposes approval of Section A of the revised RACT plan
because it does not alter the existing SIP-approved provisions for
Boiler Nos. 1, 2, 3, and 4.
Section B of the revised RACT plan contains NOX RACT and
VOC RACT provisions for the new boilers (B5, B6, and B7) that are
planned to be constructed. To comply with the VOC RACT provisions of
Regulation 6.42, Section B includes the following requirements, which
were developed as part of the construction permit \6\ issued for the
new boilers: \7\
---------------------------------------------------------------------------
\6\ The authority for ASRC to construct new boilers B5, B6 and
B7 was approved by the District through issuance of construction
permit C-0011-19-0028-V, issued on January 21, 2020. That permit is
included in the docket for this proposed rulemaking, but the permit
itself was not included in the SIP revision and EPA is not proposing
to incorporate it into the SIP.
\7\ Pursuant to the Board Order, Section A shall no longer apply
to a boiler once ASRC provides written notification to the District
that the boiler has been decommissioned.
---------------------------------------------------------------------------
(a) Paragraph 1.A. of Section B requires the VOC emissions from
each Boiler (B5, B6, and B7) to be limited by implementation of good
combustion and operating practices including the selection of efficient
burners, implementation of combustion controls to optimize efficiency,
and use of insulation media to minimize heat losses.
(b) Paragraph 1.B. of Section B requires ASRC to comply with the
tune-up requirements of 40 CFR 63.7540(a)(10) \8\ on an annual basis,
prescribes six specific annual preventative maintenance steps, and
requires the facility to maintain on-site and submit, if requested by
the Administrator, a report containing information regarding burner
efficiency before and after the tune-up of the boiler and a description
of any corrective actions taken as a part of the tune-up.
---------------------------------------------------------------------------
\8\ This reference, 40 CFR 63.7540(a)(10), is from the
continuous compliance provisions of 40 CFR part 63, subpart DDDDD--
National Emission Standards for Hazardous Air Pollutants for Major
Sources: Industrial, Commercial, and Institutional Boilers and
Process Heaters. Although boilers B5, B6, and B7 will be subject to
the requirements of subpart DDDDD, Regulation 6.42 does not provide
any exemption from the NOX and VOC RACT requirements of
the SIP on this basis.
---------------------------------------------------------------------------
For NOX RACT, the District has adopted requirements that
are similar to the existing SIP-approved requirements for Boiler Nos.
1, 2, 3, and 4, but with significantly lower NOX emission
limits. To comply with the NOX RACT provisions of Regulation
6.42, Section B includes the following requirements for the new
boilers:
(a) Paragraph 2 of Section B provides that NOX emissions
(expressed as NO2) are not to exceed 0.04 lb/MMBtu for each
boiler, based upon a 30-day rolling average. This NOX limit
for the three new natural gas-fired boilers is significantly more
stringent than the current limits for the four existing boilers (i.e.,
0.50 lb/MMBtu for coal-fired Boilers Nos. 1 and 2 and 0.20 lb/MMBtu for
natural gas-fired Boilers Nos. 3 and 4). In addition, the new boilers
are to be rated at 200 MMBtu/hr each (totaling 600 MMBtu/hr of heat
input capacity), while the boilers being replaced are rated at 212
MMBtu/hr each for Boiler Nos. 1 and 2 and 99 MMBtu/hr each for Boiler
Nos. 3 and 4 (totaling 622 MMBtu/hr of heat input capacity), therefore
resulting in an overall decrease of 22 MMBtu/hr of total heat input
capacity.
(b) Paragraphs 3 and 4 of Section B are the same as paragraphs 5.A.
and 5.B., respectively, of the existing approved Board Order for ASRC
(except for referencing the new boiler numbers and the addition of a
reference to the VOC RACT plan) and therefore do not represent a change
to existing requirements currently incorporated into the SIP. These
paragraphs pertain to NOX performance testing requirements.
(c) Paragraph (5) of Section B requires ASRC to conduct an initial
performance test and perform ongoing emissions verification on a 30-day
rolling basis, pursuant to 40 CFR part 60, subpart Db, Standards of
Performance for Industrial-Commercial-Institutional Steam Generating
Units. After the initial compliance test, NOX emissions data
shall be collected by installing, calibrating, maintaining, and
operating either a continuous emissions monitoring system pursuant to
40 CFR 60.48b(g)(1) or by predicting NOX emission rates
pursuant to 40 CFR 60.48b(g)(2).
(d) Paragraph 6 of Section B is the same as paragraph 5.C. of the
existing approved Board Order for ASRC and therefore does not represent
a change to existing requirements currently incorporated into the SIP.
This paragraph pertains to NOX performance testing
requirements.
(e) Paragraphs 7 and 8 of Section B are new requirements to help
improve boiler efficiency. Paragraph 7 requires the facility to perform
and make a record of non-routine boiler maintenance activities,
including inspection and maintenance of the fuel combustion system,
inspection and optimization of the flame pattern, inspection and
adjustment of the combustion control system, adjustment of the air-to-
fuel ratio, and inspection and adjustment of all other components of
the boiler. These maintenance
[[Page 24512]]
activities shall be completed annually within 13 months of the previous
maintenance cycle. Paragraph 8 requires ASRC to include in each semi-
annual report (required by paragraph 9) a summary of the non-routine
boiler maintenance activities.
(f) Paragraphs 9 and 10 of Section B are the same as paragraphs 6
and 7, respectively, of the existing SIP-approved Board Order for ASRC
(except for minor wording changes and that they now apply not just to
NOX but also to VOC by virtue of the addition of the VOC
RACT requirements) and therefore do not represent a change to existing
requirements currently incorporated into the SIP. Paragraph 9 pertains
to the requirement to keep a record identifying all deviations from the
requirements of the NOX and VOC RACT plan and to submit
semiannual deviation reports to the District. Paragraph 10 provides
that the facility may comply with alternatives to the requirements of
the NOX and VOC RACT plan, provided certain conditions are
met, but that the District's approval of any such alternative
requirements is not binding on EPA.
In summary, EPA proposes to approve Board Order--Amendment 2,
including the attached VOC/NOX RACT Plan, dated November 17,
2021, and issued by the Board to ASRC to replace the existing Board
Order for ASRC, and to incorporate Board Order--Amendment 2 into the
SIP because it achieves at least the same level of NOX
emission reductions as the previously SIP-approved Board Order and
meets the VOC RACT requirements of Regulation 6.42 (discussed in
Section II, above). ASRC's replacement of two existing coal-fired
boilers and two existing natural gas-fired boilers with three new
natural gas-fired boilers will achieve NOX and VOC emission
reductions at the facility, and there are no potential air pollutant
emission increases associated with this proposed SIP revision. EPA is
proposing to approve these changes because they are consistent with
SIP-approved Jefferson County Air Quality Regulation 6.42 and with the
CAA.
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 Board Order--Amendment 2, including the attached VOC/
NOX RACT Plan, for ASRC effective November 17, 2021. Also,
in this document, EPA is proposing to remove the Board Order for ASRC
effective January 1, 2001, from the Kentucky State Implementation Plan,
which is incorporated by reference in accordance with the requirements
of 1 CFR part 51. EPA has made, and will continue to make, the State
Implementation Plan generally available 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 replace the existing Board Order in the
Kentucky SIP for ASRC with Board Order--Amendment 2, including the
attached VOC/NOX RACT Plan, for ASRC effective November 17,
2021, for the reasons stated above.
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, these proposed actions:
Are 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);
Do not impose an information collection burden under the
provisions of the Paperwork Reduction Act (44 U.S.C. 3501 et seq.);
Are 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.);
Do 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);
Do not have Federalism implications as specified in
Executive Order 13132 (64 FR 43255, August 10, 1999);
Are not an economically significant regulatory action
based on health or safety risks subject to Executive Order 13045 (62 FR
19885, April 23, 1997);
Are not a significant regulatory action subject to
Executive Order 13211 (66 FR 28355, May 22, 2001);
Are 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
Do 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.
