Legal Authority for Rule Making

This rule making is proposed 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 identical to the purposes stated in ARC 4178C and 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 proposed 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 propose to 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 proposes to adopt 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 proposes to add 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 proposes to establish 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 proposing to require 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 proposes to adopt 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 is proposing adoption of 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 proposes to adopt 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 proposing adoption of 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 is proposing to adopt 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.
