 Environmental Protection Agency 40 CFR Parts 52 and 70
[EPA-R07-OAR-2022-0483; FRL-9913-01-R7]
 AGENCY: Environmental Protection Agency (EPA).
 ACTION: Proposed rule.
 SUMMARY: The Environmental Protection Agency (EPA) is proposing to approve revisions to the Iowa State Implementation Plan (SIP) and the Iowa Operating Permit Program. The revisions update incorporations by reference to EPA methods for measuring air pollutant emissions, performance testing (stack testing) and continuous monitoring. These revisions do not impact the stringency of the SIP or have an adverse effect on air quality. The EPA's proposed approval of this rule revision is being done in accordance with the requirements of the Clean Air Act (CAA).

                    *https://www.epa.gov/​dockets/​commenting-epa-dockets.* II. What is being addressed in this document? The EPA is proposing to approve revisions to the Iowa SIP and the Operating Permits Program received on October 20, 2021. The revisions incorporate recent changes to Iowa Administrative Code. The following chapters are impacted: Chapter 20, “Scope of Title—Definitions;”
                Chapter 22, “Controlling Pollution;”
                Chapter 23, “Emission Standards for Contaminants;” and
                Chapter 25, “Measurement of Emissions.” The proposed revisions update incorporations by reference to EPA methods for measuring air pollutant emissions, performance testing (stack testing) and continuous monitoring. EPA proposes to find that these revisions meet the requirements of the Clean Air Act, do not impact the stringency of the SIP, and do not adversely impact air quality. The full text of these changes can be found in the State's submission, which is included in the docket for this action. Sections 111 and 112 of the Clean Air Act (CAA) allow EPA to delegate authority to states for New Source Performance Standards (NSPS) and National Emission Standards for Hazardous Air Pollutants (NESHAPs). EPA has delegated authority to Iowa for approved portions of these sections of the CAA. Changes made to Iowa's Chapter 23 pertaining to new and revised NSPS and NESHAPs are not directly approved into the SIP, but rather, are adopted by reference. Thus, EPA is not proposing to approve the changes to Chapter 23 of the Iowa Administrative Code into the state's SIP. III. What SIP revisions are being proposed by EPA? The EPA is proposing the following revisions to the Iowa SIP: Chapter 20, Subrule 20.2, Scope of Title—Definitions: The state revised the definition of “EPA reference method” to adopt the most current performance test (stack test) method as specified in 40 CFR part 51, appendix M (as amended or corrected through October 7, 2020); 40 CFR part 60, appendix A (as amended or corrected through October 7, 2020); 40 CFR part 61, appendix B (as amended or corrected through October 7, 2020); and 40 CFR part 63, appendix A (as amended or corrected through December 2, 2020). This subrule was also revised to adopt the most current minimum performance specifications and quality assurance procedures for 
                    ( print page 36437)
                    performance evaluations of continuous monitoring systems as specified in 40 CFR part 60, appendix B (as amended or corrected through October 7, 2020); 40 CFR part 60, appendix F (as amended or corrected through October 7, 2020); 40 CFR part 75, appendix A (as amended or corrected through August 30, 2016); 40 CFR part 75, appendix B (as amended or corrected through August 30, 2016); and 40 CFR part 75, appendix F (as amended or corrected through August 30, 2016). The proposed update will ensure that state reference methods are equivalent to Federal reference methods; thus, EPA proposes to approve this change. Chapter 25, Subrule 25.1(9) Measurement of Emissions: As discussed above, the State similarly revised subrule 25.1(9),”Methods and Procedures,” to adopt the performance test (stack test) and continuous monitoring systems as specified in 40 CFR part 51, appendix M (as amended or corrected through October 7, 2020); 40 CFR part 60, appendix A (as amended or corrected through October 7, 2020); 40 CFR part 61, appendix B (as amended or corrected through October 7, 2020); 40 CFR part 63, appendix A (as amended or corrected through December 2, 2020); 40 CFR part 60, appendix B (as amended or corrected through October 7, 2020); 40 CFR part 60, appendix F (as amended or corrected through October 7, 2020); 40 CFR part 75, appendix A (as amended or corrected through August 30, 2016); 40 CFR part 75, appendix B (as amended or corrected through August 30, 2016); and 40 CFR part 75, appendix F (as amended or corrected through August 30, 2016). The proposed update will ensure that state reference methods are equivalent to Federal reference methods; thus, EPA proposes to approve this change. IV. What operating permit plan revisions are being proposed by EPA? The EPA is proposing to approve the following revision to the Operating Permit Program: Chapter 22, subrule 22.100(455B): Also as discussed above, the definition of “EPA reference method” has similarly been revised in definitions for the operating permits program to adopt performance test (stack test) and continuous monitoring systems specified by EPA in 40 CFR part 51, appendix M (as amended or corrected through October 7, 2020); 40 CFR part 60, appendix A (as amended or corrected through October 7, 2020); 40 CFR part 61, appendix B (as amended or corrected through October 7, 2020); 40 CFR part 63, appendix A (as amended or corrected through December 2, 2020), 40 CFR part 60, appendix B (as amended or corrected through October 7, 2020); 40 CFR part 60, appendix F (as amended or corrected through October 7, 2020); 40 CFR part 75, appendix A (as amended or corrected through August 30, 2016); 40 CFR part 75, appendix B (as amended or corrected through August 30, 2016); and 40 CFR part 75, appendix F (as amended or corrected through August 30, 2016). Referencing the updated method will ensure that state methods are equivalent to federal reference methods; thus, EPA proposes to approve this change. V. Have the requirements for approval of a SIP and the operating permit plan revisions been met? The State submission has met the public notice requirements for SIP submissions in accordance with 40 CFR 51.102. The submission also satisfied the completeness criteria of 40 CFR part 51, appendix V. The State provided public notice on this SIP revision from June 16, 2021, to July 19, 2021, and held a public hearing on July 19, 2021. No public comments were received. In addition, as explained above, the revision meets the substantive SIP requirements of the CAA, including section 110 and implementing regulations. VI. What action is the EPA taking? The EPA is proposing to amend the Iowa SIP and the Operating Permits Program by approving the State's request to update the definitions of “EPA Reference Method” in Iowa Administrative Code Chapter 20, “Scope of Title—Definitions;” Chapter 22, “Controlling Pollution;” and Chapter 25, “Measurement of Emissions.” We are processing this as a proposed action because we are soliciting comments on this proposed action. Final rulemaking will occur after consideration of any comments. VII. Incorporation by Reference In this document, the EPA is proposing to include regulatory text in an EPA final rule that includes incorporation by reference. In accordance with requirements of 1 CFR 51.5, the EPA is proposing to incorporate by reference Iowa rules 567-20.2, 567-22.100 and 567-25.1 as described in Sections II-IV of this preamble and set forth below in the proposed amendments to 40 CFR part 52. The EPA has made, and will continue to make, these materials generally available through 
                    *www.regulations.gov*
                     and at the EPA Region 7 Office (please contact the person identified in the 
                    **FOR FURTHER INFORMATION CONTACT**
                     section of this preamble for more information). VIII. Statutory and Executive Order Reviews Under the Clean Air Act (CAA), the Administrator is required to approve a SIP submission that complies with the provisions of the Act and applicable Federal regulations. 42 U.S.C. 7410(k); 40 CFR 52.02(a). Thus, in reviewing SIP submissions, the 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 inExecutive Order 13132 (64 FR 43255, August 10, 1999);
                Is not an economically significant regulatory action based on health or safety risks subject toExecutive Order 13045 (62 FR 19885, April 23, 1997);
                Is not a significant regulatory action subject toExecutive Order 13211 (66 FR 28355, May 22, 2001);
                Is not subject to requirements of the National Technology Transfer and Advancement Act (NTTA) because this rulemaking does not involve technical standards; 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, underExecutive 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( print page 36438)
                    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). List of Subjects 40 CFR Part 52 Environmental protection
