Regulatory Analysis of Proposed Air Quality Rule Changes for Public Comment
The Department of Natural Resources (DNR) has published a Regulatory Analysis to propose changes to Air Quality Bureau rules. The Regulatory Analysis will available at Iowa Administrative Bulletin on March 18, 2026.
Summary of Proposed Rule Changes
The proposed changes adopt voluntary alternative federal test methods, citation corrections, and amended federal new source performance standards (NSPS) and National Emissions Standards for Hazardous Air Pollutants (NESHAP). Adopting EPA’s amendments allows state rules to be consistent with federal regulations and provides certainty to affected businesses and other interested stakeholders. The proposed changes will also require the electronic submittal of Asbestos NESHAP notifications for demolitions and renovations.

The DNR invites the public to provide comments on the 2026 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.
Anyone may make written suggestions or comments on the report. Written comments must be received by Thursday, June 11, 2026, and may be sent via e-mail to jessica.reesemcintyre@dnr.iowa.gov.

Iowa’s 2026 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.
Legislation passed by the 86th session of Iowa General Assembly (Senate File 488) established authority to collect application fees for new source air construction permits at major sources. Construction permit application fees will pay for the reasonable direct and indirect costs of implementing and administrating new source review programs for major sources. The legislation directs the DNR to convene a fee advisory group to obtain recommendations regarding these fees for major source air construction permits, including Prevention of Significant Deterioration (PSD) permits. The advisory group will meet at least once annually to consider the fees. For more information contact Wendy Walker at Wendy.Walker@dnr.iowa.gov or 515-250-7534.
