Air Plan Approval; Indiana; Monitoring Requirements, 15838-15840 [2021-06166]

Download as PDF 15838 Federal Register / Vol. 86, No. 56 / Thursday, March 25, 2021 / Proposed Rules documents. On March 30, 2018 (83 FR 30571), EPA approved the consolidation of adopted by reference materials in Part 9, R 336.1902 into the Michigan SIP. II. EPA’s Analysis of EGLE’s Submittal In the December 18, 2020 submission, EGLE revised R 336.1902 to include additional reference materials to maintain consistency between rules contained in the SIP and Michigan’s Air Pollution Control Rules. The changes to Part 9 are administrative, revising R 336.1902 to include more adoption by reference material aforementioned by adding the following subrules to R 336.1902: (1)(b)(ii), (1)(b)(vi), (1)(o), (1)(o)(vi), (1)(r) to (u), (2)(d), (3)(b), (4)(g) to (k), (6)(a) to (d), and (10) (See tables 1–14 of EGLE’s submission for details). Also, the changes to R 336.1902 reflect the most up-to-date version of the materials adopted by reference currently approved in Michigan’s SIP. Section 110(l) Analysis of the State’s Submittal EPA is proposing to approve the revision to Part 9, as discussed above because it meets all applicable requirements under the Clean Air Act (CAA). Furthermore, EGLE has shown that the revision to Part 9 does not interfere with any applicable requirement concerning attainment and reasonable further progress or any other applicable CAA requirement, consistent with section 110(l) of the CAA. Under Section 110(l) of the CAA, EPA shall not approve a SIP revision if it would interfere with any applicable requirement concerning attainment and reasonable further progress (as defined in section 171 of the CAA) or any other applicable requirement of the CAA. The proposed SIP revision will not interfere with any applicable CAA requirements based on the technical analysis submitted by EGLE. In Part 9, R 336.1902 contains materials that are adopted by reference and are strictly administrative in nature. Thus, the revision will have no effect on actual or allowable emissions. III. What action is EPA taking? EPA is proposing to approve the revision to Part 9 into Michigan’s SIP, as submitted on December 18, 2020. IV. 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 Michigan’s Air Pollution Control Rules, Chapter 336, Part 9, R 336.1902 VerDate Sep<11>2014 17:19 Mar 24, 2021 Jkt 253001 ‘‘Adoption by reference’’, effective on November 18, 2018. EPA has made, and will continue to make, these documents generally available through www.regulations.gov and at the EPA Region 5 Office (please contact the person identified in the FOR FURTHER INFORMATION CONTACT section of this preamble for more information). 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 CAA and applicable Federal regulations. 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 action merely approves 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 PO 00000 Frm 00039 Fmt 4702 Sfmt 4702 methods, under Executive Order 12898 (59 FR 7629, February 16, 1994). In addition, 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 and will not impose substantial direct costs on tribal governments or preempt tribal law as specified by Executive Order 13175 (65 FR 67249, November 9, 2000).

SUPPLEMENTARY INFORMATION: Throughout this document whenever ‘‘we,’’ ‘‘us,’’ or ‘‘our’’ is used, we mean EPA. I. Background On July 24, 2020, the Indiana Department of Environmental Management (IDEM) submitted a request to approve a revision to the Indiana SIP to address changes to the monitoring requirements at 326 IAC 3– 5–1 for Portland cement plants. This revision will allow a single monitoring method to demonstrate compliance with various provisions of the SIP. IDEM revised its rule to be consistent with EPA’s revision to the National Emission Standards for Hazardous Air Pollutants (NESHAP) governing Portland cement plants. EPA previously revised 40 part 63, subpart LLL, the NESHAP for the Portland Cement Manufacturing Industry, on September 9, 2010 (75 FR 54969). This revision removed opacity limits for most Portland cement plant units, including for Portland cement plants’ kilns and clinker cooler units because it found PM emissions data to be a more accurate measure to monitor compliance with PM emission limits. Under the revised NESHAP, those units VerDate Sep<11>2014 17:19 Mar 24, 2021 Jkt 253001 15839 were required to monitor emissions with a PM continuous emissions monitoring system (CEMS) instead of a continuous opacity monitoring system (COMS). On February 12, 2013, EPA again revised the NESHAP, 40 part 63, subpart LLL (78 FR 10006). The revision updated the PM monitoring requirements for Portland cement plants to replace the compliance basis for PM from monitoring with a CEMS to require a PM continuous parametric monitoring system (CPMS). EPA found technical issues with monitoring PM emissions at Portland cement plants with CEMS because of the size and variability of PM generated by a cement kiln. A PM CPMS system responds to changes in PM concentration of the exhaust allowing Portland cement plants to better determine compliance. The NESHAP provides the requirements for establishing the parametric operating limits for subject units and requires sources to conduct an annual test that resets the PM CPMS operating limit and sets the standards for continuous monitoring. Indiana has revised 326 IAC 3–5–1 to allow Portland cement plants to monitor, with a PM CPMS, its kiln or clinker cooler units as an alternate to COMS. Indiana’s 326 IAC 3–5–1, as currently approved into the Indiana SIP for PM, requires monitoring with COMS or PM CEMS, while the 2013 NESHAP requires monitoring with PM CPMS. This revision allows Portland cement plants to meet the monitoring requirements for kiln and clinker cooler units with one monitoring system, PM CPMS. Otherwise, Portland cement plants would have to operate two monitoring systems to satisfy the differing SIP and NESHAP requirements. III. What is EPA’s analysis of the revisions? II. How has the rule been revised? EPA is proposing to approve revisions to 326 IAC 3–5–1, continuous monitoring requirements, into the Indiana SIP. Indiana revised 326 IAC 3–5–1 (c) to add 326 IAC 3–5–1 (c)(2) that allows Portland cement plants to monitor with a PM CPMS. That rule sets the requirements for the PM CPMS. Those include satisfying the requirements in 40 part 63, subpart LLL. Thus, Portland cement plants in Indiana will have the option of monitoring with COMS, PM CEMS, or PM CPMS in the revised 326 IAC 3–5–1. Indiana retained 326 IAC 3–5–1 (c)(1) where the requirements for sources, not limited to Portland cement plants, that monitor with a PM CEMS are found. The remaining revisions to 326 IAC 3– 5–1 are administrative revisions such as changing ‘‘shall’’ to ‘‘must.’’ PO 00000 Frm 00040 Fmt 4702 Sfmt 4702 Indiana provided a Clean Air Act (CAA) 110(l) analysis as a supplement to it submission. CAA Section 110(l) prohibits EPA from approving a SIP revision if that revision would interfere with any applicable requirement concerning attainment, reasonable further progress, or any other CAA requirement. Indiana concluded that the 326 IAC 3–5–1 revision will not result in an increase in emissions or interfere with Indiana’s obligations under the CAA. The State concluded that since Portland cement plants are subject to limits under 40 CFR 63, subpart LLL that are at least as stringent as the State rule. Indiana states that the strict PM emission limits and continuous monitoring requirements have rendered the COMS requirements of 326 IAC 3– 5 obsolete for Portland cement plants. EPA concurs with Indiana’s CAA 110(l) analysis that the revision does not interfere with any applicable requirement concerning attainment or any other applicable requirement of the CAA because it is simply revising the monitoring requirements. EPA, in 40 CFR 63, subpart LLL, Portland cement plants must use PM CPMS to show compliance with the Federal standard. Indiana’s rule required such units to monitor with COMS or request Department permission to alternatively operate a PM CEMS. The revised 326 IAC 3–5–1 adds the option for Portland cement plants to alternatively operate a PM CPMS in accordance with 40 CFR part 63, subpart LLL requirements. EPA finds that the revised 326 IAC 3– 5–1 is consistent with the requirements of 40 part 63, subpart LLL. Indiana’s revisions follow the revisions EPA made to the NESHAP. IV. What action is EPA taking? V. Incorporation by Reference In this action, 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 Title 326 of the Indiana Administrative Code Article 3, Rule 5, Section 1 Applicability; continuous monitoring requirements for applicable pollutants, effective April 24, 2020.

SUPPLEMENTARY INFORMATION: Throughout this document whenever ``we,'' 
``us,'' or ``our'' is used, we mean EPA.

I. Background

    On July 24, 2020, the Indiana Department of Environmental 
Management (IDEM) submitted a request to approve a revision to the 
Indiana SIP to address changes to the monitoring requirements at 326 
IAC 3-5-1 for Portland cement plants. This revision will allow a single 
monitoring method to demonstrate compliance with various provisions of 
the SIP. IDEM revised its rule to be consistent with EPA's revision to 
the National Emission Standards for Hazardous Air Pollutants (NESHAP) 
governing Portland cement plants.
    EPA previously revised 40 part 63, subpart LLL, the NESHAP for the 
Portland Cement Manufacturing Industry, on September 9, 2010 (75 FR 
54969). This revision removed opacity limits for most Portland cement 
plant units, including for Portland cement plants' kilns and clinker 
cooler units because it found PM emissions data to be a more accurate 
measure to monitor compliance with PM emission limits. Under the 
revised NESHAP, those units were required to monitor emissions with a 
PM continuous emissions monitoring system (CEMS) instead of a 
continuous opacity monitoring system (COMS).
    On February 12, 2013, EPA again revised the NESHAP, 40 part 63, 
subpart LLL (78 FR 10006). The revision updated the PM monitoring 
requirements for Portland cement plants to replace the compliance basis 
for PM from monitoring with a CEMS to require a PM continuous 
parametric monitoring system (CPMS). EPA found technical issues with 
monitoring PM emissions at Portland cement plants with CEMS because of 
the size and variability of PM generated by a cement kiln. A PM CPMS 
system responds to changes in PM concentration of the exhaust allowing 
Portland cement plants to better determine compliance. The NESHAP 
provides the requirements for establishing the parametric operating 
limits for subject units and requires sources to conduct an annual test 
that resets the PM CPMS operating limit and sets the standards for 
continuous monitoring.
    Indiana has revised 326 IAC 3-5-1 to allow Portland cement plants 
to monitor, with a PM CPMS, its kiln or clinker cooler units as an 
alternate to COMS. Indiana's 326 IAC 3-5-1, as currently approved into 
the Indiana SIP for PM, requires monitoring with COMS or PM CEMS, while 
the 2013 NESHAP requires monitoring with PM CPMS. This revision allows 
Portland cement plants to meet the monitoring requirements for kiln and 
clinker cooler units with one monitoring system, PM CPMS. Otherwise, 
Portland cement plants would have to operate two monitoring systems to 
satisfy the differing SIP and NESHAP requirements.

II. How has the rule been revised?

    Indiana revised 326 IAC 3-5-1 (c) to add 326 IAC 3-5-1 (c)(2) that 
allows Portland cement plants to monitor with a PM CPMS. That rule sets 
the requirements for the PM CPMS. Those include satisfying the 
requirements in 40 part 63, subpart LLL. Thus, Portland cement plants 
in Indiana will have the option of monitoring with COMS, PM CEMS, or PM 
CPMS in the revised 326 IAC 3-5-1.
    Indiana retained 326 IAC 3-5-1 (c)(1) where the requirements for 
sources, not limited to Portland cement plants, that monitor with a PM 
CEMS are found. The remaining revisions to 326 IAC 3-5-1 are 
administrative revisions such as changing ``shall'' to ``must.''

III. What is EPA's analysis of the revisions?

    Indiana provided a Clean Air Act (CAA) 110(l) analysis as a 
supplement to it submission. CAA Section 110(l) prohibits EPA from 
approving a SIP revision if that revision would interfere with any 
applicable requirement concerning attainment, reasonable further 
progress, or any other CAA requirement. Indiana concluded that the 326 
IAC 3-5-1 revision will not result in an increase in emissions or 
interfere with Indiana's obligations under the CAA. The State concluded 
that since Portland cement plants are subject to limits under 40 CFR 
63, subpart LLL that are at least as stringent as the State rule. 
Indiana states that the strict PM emission limits and continuous 
monitoring requirements have rendered the COMS requirements of 326 IAC 
3-5 obsolete for Portland cement plants.
    EPA concurs with Indiana's CAA 110(l) analysis that the revision 
does not interfere with any applicable requirement concerning 
attainment or any other applicable requirement of the CAA because it is 
simply revising the monitoring requirements. EPA, in 40 CFR 63, subpart 
LLL, Portland cement plants must use PM CPMS to show compliance with 
the Federal standard. Indiana's rule required such units to monitor 
with COMS or request Department permission to alternatively operate a 
PM CEMS. The revised 326 IAC 3-5-1 adds the option for Portland cement 
plants to alternatively operate a PM CPMS in accordance with 40 CFR 
part 63, subpart LLL requirements.
    EPA finds that the revised 326 IAC 3-5-1 is consistent with the 
requirements of 40 part 63, subpart LLL. Indiana's revisions follow the 
revisions EPA made to the NESHAP.

IV. What action is EPA taking?

    EPA is proposing to approve revisions to 326 IAC 3-5-1, continuous 
monitoring requirements, into the Indiana SIP.

V. Incorporation by Reference

    In this action, 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 Title 326 of the Indiana Administrative Code Article 3, Rule 
5, Section 1 Applicability; continuous monitoring requirements for 
applicable pollutants, effective April 24, 2020. EPA has made, and will 
continue to make, these documents generally available through

VI. Statutory and Executive Order Reviews

    Under the CAA, the Administrator is required to approve a SIP 
submission that complies with the provisions of the CAA and applicable 
Federal regulations. 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 
action merely approves 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
