Regulatory Analysis for Proposed Air Quality Fee Rulemaking

The Department of Natural Resources (DNR) has published a Regulatory Analysis in the May 14th Iowa Administrative Bulletin to propose changes to Air Quality Bureau fees. The Regulatory Analysis is the first step in the formal rulemaking process prior to the rule proposal. The Regulatory Analysis can be found at https://www.legis.iowa.gov/docs/aco/bulletin/05-14-2025.pdf.

Background

DNR currently charges fees for Title V emissions inventories, Title V applications, construction permit (new source review) applications, and asbestos demolition and renovation notifications. The air quality rules in 567 Iowa Administrative Code (IAC) Chapter 30 specify both the fee requirements and maximum fee rates. Annually, DNR reviews the fees with stakeholders and sets the amount for the coming year. Fee rates are currently at the maximum allowed by rule and have not changed in 10 years. The current fee schedule is available at https://www.iowadnr.gov/aqfees. 

Maximum Fee Amounts

The proposed changes to the maximum fee amounts can be found in the Regulatory Analysis. The proposals represent the consensus opinion of a small but diverse group of industrial stakeholders DNR asked to evaluate our budget, revenue, staffing, and expenses. The group held three public meetings to share ideas and gather additional input from any impacted individuals before deciding on their proposal.

When Might Air Quality Fees Increase?

The earliest fees could increase would be July 1, 2026. If the rule changes are approved, DNR will discuss new fee amounts at the annual stakeholder meeting in January/February 2026. The proposed fee increases would be presented at the March 2026 Environmental Protection Commission meeting with approval requested at the May 2026 meeting.

Public Comment and Public Hearing

DNR will be accepting comment on the Regulatory Analysis through June 3rd and will hold an online public hearing on June 3, 2025 at 1:00 p.m. via Zoom.

Final Air Quality Rules and Rule Change Crosswalk

After providing stakeholder engagement and considering both informal input and formal public comments, the DNR has finalized air quality rule changes to implement Executive Order 10 (EO10). The final rules for section 567 Iowa Administrative Code (IAC), Chapters 15 and 20-35, were published on May 15, 2024, in the Iowa Administrative Bulletin and in the IAC Supplement (available at legis.iowa.gov/law/administrativeRules/bulletinSupplementListings.) The rule changes became effective on June 19, 2024. The updated 567 IAC with the new chapters can also be accessed at legis.iowa.gov/law/administrativeRules/agencies.

For assistance navigating the new air quality rules, please access the EO10 Rules Crosswalk:

Background on Executive Order 10

Executive Order 10 (EO10) signed by the Governor on January 10, 2023, requires all state agencies to identify which administrative rule chapters will be retained or rescinded. For more information on EO10 please go to the Governor's Office webpage for Executive Orders.

The EO10 process for both the review of existing rule chapters and the reauthorization of rule chapters that will be retained includes public engagement with the opportunity for meaningful input throughout the process. Opportunities for public input and information for public review during the Air Quality Bureau's implementation of EO10 will be posted below as they become available.

EO10 Stakeholder Meetings and Materials

At these meetings, held March 14, May 18, June 15, and July 11, the Air Quality Bureau shared its EO10 implementation plans, schedules, and draft rule changes. Stakeholders had the opportunity to provide feedback and informal comments at the meetings and during the informal review period following each meeting.

The DNR invites the public to provide comments on the 2025 report for the sulfur dioxide (SO2) Data Requirements Rule (DRR). The DRR requires an annual assessment of recent SO2 emissions in any area where air quality modeling of actual emissions provided the basis for designating the area attainment for the 2010 1-hour SO2 national ambient air quality standard (NAAQS).

Two areas in Iowa are currently subject to this review, Louisa County and Pottawattamie County. The DNR is recommending that no additional modeling is needed to conclude that these areas continue to attain the 2010 1-hour SO2 NAAQS. This recommendation is based on documented reductions in SO2 emissions.

The DNR invites the public to provide comment on Iowa’s Progress Report for the second 10-year regional haze planning period (2019-2028). The draft report analyzes emissions changes in the state, evaluates the adequacy of Iowa’s current regional haze control measures, and documents consultation activities with the Federal Land Managers.

The goal of the U.S. Environmental Protection Agency’s (EPA) regional haze program is to eliminate anthropogenic visibility impairment in 156 protected parks and wilderness areas (“Class I areas”). There are no Class I areas in Iowa, but all states must submit 10-year regional haze plans that provide for reasonable reductions in their emissions of visibility-impairing air pollutants. EPA’s regulations also require the periodic submittal of progress reports, pursuant to 40 CFR 51.308(g), (h), and (i). Find Iowa’s draft Progress Report for the second regional haze planning period at the links below.

Iowa’s 2025 Air Monitoring Network Plan is available for public review and comment.

The air monitoring network plan will assist the Iowa DNR in its efforts to monitor the quality of Iowa’s air and to keep the public aware of air quality problems.  

The plan is required by EPA’s national ambient air monitoring regulations.  It contains detailed information about the location and purpose of any monitor in Iowa’s air monitoring network that produces data for comparison with national ambient air quality standards. 

The plan and comments will be submitted to EPA after a 30 day review period.
