                   ENVIRONMENTAL PROTECTION COMMISSION[567]
                               Adopted and Filed
                        Rule making related to air quality
The Environmental Protection Commission hereby amends Chapter 20, "Scope of Title -- Definitions," Chapter 22, "Controlling Pollution," Chapter 23, "Emission Standards for Contaminants," and Chapter 25, "Measurement of Emissions," Iowa Administrative Code.
                           Legal Authority for Rule Making
      This rule making is adopted under the authority provided in Iowa Code section 455B.133.
                          State or Federal Law Implemented
      This rule making implements, in whole or in part, Iowa Code section 455B.133.
                                 Purpose and Summary
      The purposes of this rule making are to:
      1. Reduce the cost of government while providing streamlined services to the public and regulated community.
      2. Update rules to provide regulatory certainty and flexibility. The amendments implement a portion of the Department of Natural Resources' (Department's) five-year review of rules plan to accomplish the requirements of Iowa Code section 17A.7(2).
      3. Offer uniform rules by making changes that match federal regulations and eliminate inconsistencies between federal regulations and state administrative rules. By adopting federal updates into state administrative rules, the Commission is ensuring that Iowa's air quality rules are no more stringent than federal regulations. Additionally, the updates allow the Department, rather than the U.S. Environmental Protection Agency (EPA), to be the primary agency to implement the air quality requirements in Iowa, thereby allowing the Department to provide compliance assistance and outreach to affected facilities.
      Items 1 and 6 amend the definition of "EPA reference method" to adopt the technical corrections that EPA made to continuous methods for measuring air pollutant emissions. The corrections were published on August 7, 2017, in the Federal Register and codified in 40 Code of Federal Regulations (CFR) Part 60, Appendix B. Item 15 also adopts these federal updates into the methods and procedures established in Chapter 25 for continuous monitoring systems. Adopting EPA's updates ensures that state reference methods match current federal reference methods and are no more stringent than the federal methods. 
      Item 2 adds a cross reference to the rules for nonattainment areas specified in Chapter 31 of the Commission's rules.
      Items 3, 4, 5, 7, 9, 10 and 11 update the location and mailing address for the Department's Air Quality Bureau.
      Item 8 establishes electronic submittal of the annual emissions inventories required under the Title V operating permit program. To simplify the reporting requirements for industry, increase reporting efficiency and reduce cost to the state, the Commission is requiring the use of electronic reporting for all Title V facilities, beginning with reports due to the Department by March 31, 2019.
      Facilities required to obtain Title V permits are required to annually report their actual air pollution emissions. "Title V facilities" are those that are permitted to emit over 100 tons of air pollution annually (or significant levels of specified hazardous air pollutants). There are currently 289 Title V facilities in Iowa, including electric generating utilities, grain-processing facilities, manufacturing plants, and others.
      The Department has since 2002 offered an electronic submission system for reporting air pollution emissions. In 2015, SLEIS (the State and Local Emissions Inventory System) was introduced, offering a significantly more streamlined method for reporting. This year, 82 percent of Title V facilities submitted their inventories on SLEIS, the current e-submittal system for emissions inventories. Annually, the Department provides in-person emissions inventory and SLEIS user training at several locations in the state. Online training tutorials also are available on demand on the Department's website.
      Item 12 amends subrule 23.1(2) to adopt by reference new and revised New Source Performance Standards (NSPS).
      The Commission adopts the federal NSPS for sewage sludge incineration (SSI) units. The federal regulation was published in the Federal Register on March 21, 2011, and applies to SSI units for which construction or reconstruction commenced after October 14, 2010, or for which modification commenced after September 21, 2011. Since its publication, the SSI NSPS has been subject to reconsideration petitions and litigation. The Commission adopts these federal amendments because EPA's reconsiderations and the litigation of the federal standards have recently been resolved.
      At this time, no facilities in Iowa are affected by this NSPS. A facility that constructs a new SSI unit, or an existing facility that modifies its SSI unit, could become subject to this NSPS in the future. (See Item 14 for a related amendment.)
      The amendment in Item 12 also adopts the changes EPA made to the NSPS test methods, as explained in the description above for Items 1, 6 and 15. The amendments to the NSPS are adopted by reference through revision of the adoption date specified in the introductory paragraph of subrule 23.1(2).
      Item 13 amends subrule 23.1(4) to adopt federal amendments to the federal National Emission Standards for Hazardous Air Pollutants (NESHAP) for source categories, as described below. The federal amendments are adopted by reference through revision of the adoption date specified in the introductory paragraph of subrule 23.1(4). The text in parentheses in each section heading below indicates the applicable subpart in 40 CFR Part 63 and the corresponding paragraph in subrule 23.1(4).
      Phosphoric Acid Manufacturing and Phosphate Fertilizer Production (Subpart AA; paragraph "aa")
      Updates to this NESHAP were published in the Federal Register on September 28, 2017. In response to petitions for reconsideration from stakeholders, EPA extended some compliance dates for affected sources and clarified one option and added a new option for monitoring requirements. At this time, no facilities in Iowa are affected by this NESHAP. New facilities, or existing facilities that change their production lines, could become subject to this NESHAP in the future.
      Offsite Waste and Recovery Operations (Subpart DD; paragraph "ad")
      The amendment adopts changes to the standards for offsite waste and recovery operations published in the Federal Register on January 29, 2018. EPA's final amendments address petitions for reconsideration regarding requirements for continuous monitoring of pressure relief devices (PRDs) on containers. EPA's action removes the additional monitoring requirements for PRDs on containers because EPA determined that the requirements were unnecessary. At this time, no facilities in Iowa are affected by this NESHAP. New facilities, or existing facilities that change their production lines, could become subject to this NESHAP in the future.
      Chemical Recovery Combustion Sources at Kraft, Soda, Sulfite, and Stand-Alone Semichemical Pulp Mills (Subpart MM; paragraph "am")
      EPA's rule amendments published in the Federal Register on October 11, 2017, include reducing the opacity (visible emissions) monitoring allowance for recovery furnaces and for lime kilns, adding electronic reporting requirements for semiannual compliance reports, updating monitoring and testing requirements, and requiring periodic stack testing and electronic reporting of stack test results. At this time, no facilities in Iowa are affected by this NESHAP. New facilities, or existing facilities that change their production lines, could become subject to this NESHAP in the future.
      Portland Cement Manufacturing (Subpart LLL, paragraph "bl")
      EPA's amendments to this NESHAP were published in the Federal Register on July 25, 2018, and August 3, 2018, and reflect corrections and clarifications of the rule requirements and provisions. EPA states that the amendments result in improved monitoring, compliance, and implementation of the rule. This NESHAP affects three facilities in Iowa (one facility is currently idled).
      Wool Fiberglass Manufacturing (Subpart NNN; paragraph "bn")
      Amendments to this NESHAP were published in the Federal Register on December 26, 2017. EPA revised the federal standard to require affected facilities to conduct additional monitoring and record-keeping activities. In addition, affected facilities with flame attenuation lines will need to demonstrate compliance with new emission standards. EPA provided existing affected facilities a three-year period in which to comply with new NESHAP requirements. At this time, no facilities in Iowa are affected by this NESHAP. New facilities, or existing facilities that change their production lines, could become subject to this NESHAP in the future.
      Item 14 adopts by reference the federal Emission Guidelines for existing SSI units. EPA's Emission Guidelines provide "model rules" that states may adopt by reference in setting the requirements for existing sources. When a state does not have an approved State Plan by EPA's specified deadline, EPA promulgates a Federal Plan for affected facilities in 40 CFR Part 62 with rules essentially identical to the model rules. EPA's Federal Plan for existing SSI is set forth in 40 CFR Part 62.
      Concurrent with the NSPS for SSI units described above in Item 12, EPA published the Emission Guidelines for SSI units in the Federal Register on March 21, 2011. The standards apply to SSI units for which construction or reconstruction commenced on or before October 14, 2010. As with the NSPS, the Emission Guidelines have been subject to reconsideration petitions and litigation since publication. The Commission is adopting the federal regulations for existing SSI units because EPA's reconsiderations and the litigation of the federal standards have recently been resolved. One facility in Iowa is currently affected by these amendments.
      As with the NSPS and NESHAP, the Commission adopts EPA's Emission Guidelines by reference so that the requirements are no more or less stringent than federal requirements. In this case, the Commission adopts EPA's Federal Plan for SSI units (rather than the model rules for states) because the one facility affected by the Emission Guidelines is already complying with the Federal Plan, as set forth in 40 CFR Part 62, Subpart LLL. Adoption of the provisions in Subpart LLL will provide regulatory certainty and continuity for the affected facility.
                      Public Comment and Changes to Rule Making
      Notice of Intended Action for this rule making was published in the Iowa Administrative Bulletin on December 19, 2018, as ARC 4178C. An Amended Notice of Intended Action was published in the Iowa Administrative Bulletin on January 2, 2019, as ARC 4221C. A public hearing was held on January 22, 2019, at 1 p.m.	in Conference Room 4 East, Wallace State Office Building, Des Moines, Iowa. One person attended the public hearing but did not provide any comments. The Department received one written comment prior to the January 22, 2019, deadline for public comments. The comment provided was outside the scope of the rule making. No changes from the Notice have been made.
                               Adoption of Rule Making
      This rule making was adopted by the Commission on February 19, 2019.
                                    Fiscal Impact
      This rule making has no fiscal impact to the State of Iowa. After analysis and review of this rule making, the Commission has determined that most of the changes will have a neutral fiscal impact on affected facilities, the general public, and counties or local governments. The Commission does note that some of the amendments may benefit the private sector because they streamline current air quality programs. Affected businesses and the public benefit from up-to-date air quality requirements and increased effectiveness. A copy of the fiscal impact statement is available from the Department upon request.
                                     Jobs Impact
      After analysis and review of this rule making, the Commission has determined that the amendments specified in Items 1 through 11 and Item 15 will have a neutral impact on private sector jobs. The Commission does note that some of the amendments may benefit the private sector because they streamline current air quality programs. For the amendments specified in Items 12, 13 and 14, the Commission has determined that there may be jobs impacts to Iowa businesses. However, the amendments are only implementing federally mandated regulations. The amendments are identical to the federal regulations and would not impose any regulations on Iowa businesses not already required by federal law. In some cases, the revised federal standards being adopted provide more flexibility and potential cost savings for affected businesses, offering a positive impact on private sector jobs. A copy of the complete jobs impact statement is available from the Department upon request.
                                       Waivers
      Any person who believes that the application of the discretionary provisions of this rule making would result in hardship or injustice to that person may petition the Department for a waiver of the discretionary provisions, if any, pursuant to 561 -- Chapter 10.
                   Review by Administrative Rules Review Committee
      The Administrative Rules Review Committee, a bipartisan legislative committee which oversees rule making by executive branch agencies, may, on its own motion or on written request by any individual or group, review this rule making at its regular monthly meeting or at a special meeting. The Committee's meetings are open to the public, and interested persons may be heard as provided in Iowa Code section 17A.8(6).
                                   Effective Date
      This rule making will become effective on April 17, 2019.

      Item 12. Amend subrule 23.1(2) as follows:
      23.1(2) New source performance standards. The federal standards of performance for new stationary sources, as defined in 40 Code of Federal Regulations Part 60 as amended or corrected through September 14, 2016 August 7, 2017, are adopted by reference, except § 60.530 through § 60.539b (Part 60, Subpart AAA), and shall apply to the following affected facilities. The corresponding 40 CFR Part 60 subpart designation is in parentheses. An earlier date for adoption by reference may be included with the subpart designation in parentheses. Reference test methods (Appendix A), performance specifications (Appendix B), determination of emission rate change (Appendix C), quality assurance procedures (Appendix F) and the general provisions (Subpart A) of 40 CFR Part 60 also apply to the affected facilities.
      a. to bbbb.  No change.
      cccc. 	 Sewage sludge incineration units. Each sewage sludge incineration (SSI) unit for which construction or reconstruction commenced after October 14, 2010, or for which modification commenced after September 21, 2011, must comply. (Subpart LLLL)
      
      Item 13. Amend subrule 23.1(4), introductory paragraph, as follows:
      23.1(4) Emission standards for hazardous air pollutants for source categories. The federal standards for emissions of hazardous air pollutants for source categories, 40 Code of Federal Regulations Part 63 as amended or corrected through September 14, 2016 August 3, 2018, are adopted by reference, except those provisions which cannot be delegated to the states. The corresponding 40 CFR Part 63 subpart designation is in parentheses. An earlier date for adoption by reference may be included with the subpart designation in parentheses. 40 CFR Part 63, Subpart B, incorporates the requirements of Clean Air Act Sections 112(g) and 112(j) and does not adopt standards for a specific affected facility. Test methods (Appendix A), sources defined for early reduction provisions (Appendix B), and determination of the fraction biodegraded (Fbio) in the biological treatment unit (Appendix C) of Part 63 also apply to the affected activities or facilities. For the purposes of this subrule, "hazardous air pollutant" has the same meaning found in 567 -- 22.100(455B). For the purposes of this subrule, a "major source" means any stationary source or group of stationary sources located within a contiguous area and under common control that emits or has the potential to emit, considering controls, in the aggregate, 10 tons per year or more of any hazardous air pollutant or 25 tons per year or more of any combination of hazardous air pollutants, unless a lesser quantity is established, or in the case of radionuclides, where different criteria are employed. For the purposes of this subrule, an "area source" means any stationary source of hazardous air pollutants that is not a "major source" as defined in this subrule. Paragraph 23.1(4)"a," general provisions (Subpart A) of Part 63, shall apply to owners or operators who are subject to subsequent subparts of 40 CFR Part 63 (except when otherwise specified in a particular subpart or in a relevant standard) as adopted by reference below.
      
      Item 14. Amend subrule 23.1(5) as follows:
      23.1(5) Emission guidelines. The emission guidelines and compliance times for existing sources, as defined in 40 Code of Federal Regulations Part 60 as amended through June 9, 2006 March 21, 2011, shall apply to the following affected facilities. The corresponding 40 CFR Part 60 subpart designation is in parentheses. An earlier A different CFR reference and date for adoption by reference may be included with the subpart designation in parentheses indicated in the paragraphs of this subrule. The control of the designated pollutants will be in accordance with federal standards established in Sections 111 and 129 of the Act and 40 CFR Part 60, Subpart B (Adoption and Submittal of State Plans for Designated Facilities), and the applicable subpart(s) for the existing source. Reference test methods (Appendix A), performance specifications (Appendix B), determination of emission rate change (Appendix C), quality assurance procedures (Appendix F) and the general provisions (Subpart A) of 40 CFR Part 60 also apply to the affected facilities.
      a. to d.  No change.
      e. 	Emission guidelines and compliance times for existing sewage sludge incineration units (40 CFR Part 62, Subpart LLL).  Emission guidelines and compliance times for control of designated pollutants from affected sewage sludge incineration (SSI) units that commenced construction or reconstruction on or before October 14, 2010, shall be in accordance with federal standards established in Subpart LLL of 40 CFR Part 62, as amended through April 29, 2016.
      
      Item 15. Amend subrule 25.1(9) as follows:
      25.1(9) Methods and procedures. Stack sampling and associated analytical methods used to evaluate compliance with emission limitations of 567 -- Chapter 23 or a permit condition are as follows:
