The Air Quality Bureau frequently seeks input and recommendations from stakeholders on various planning and rulemaking activities, along with permits that will be issued.
Interested members of the public can view agendas, documents, and general information; meeting and workgroup activities can also be tracked.
Please note that not all categories will have items available for comment at all times. Public meetings being held throughout the state are also available on the State of Iowa public meeting calendar.
* The Iowa DNR is proposing to issue these construction permit(s). Written comments should be directed immediately to the assigned engineer.
*Please see the changes to the format of the public hearing noted below.*
The Environmental Protection Commission (Commission) has approved a proposed air quality rulemaking for formal public comment.
Reason for Rulemaking
Affected businesses and the public benefit from up-to-date air quality requirements and increased effectiveness.
The proposed changes to air quality rules:
Summary of Proposed Rule Changes
The proposed rule changes continue previous efforts to improve rules for air quality programs.
Facilitate Electronic Reporting for EASY Air
The proposal will help facilitate the Iowa DNR's launch of the Iowa Environmental Application System - EASY Air. EASY Air is a new online electronic method for submitting air quality permit applications, registrations, notifications, and template applications and is expected to make application preparation easier, improve customer service and speed the Iowa DNR’s ability to issue permits while increasing data accuracy and cutting costs.
Clarify Requirements for Industrial Anaerobic Lagoons
The proposal updates the definition of “anaerobic lagoon” to clarify that this definition is applicable to only air quality requirements. Other Iowa DNR regulations, such as those for wastewater, may have different meanings for the term “anaerobic lagoon” that are specific to that particular program area. The proposal also includes removing two operating limits for industrial anaerobic lagoons and adding the siting requirement that is in Iowa Code section 455.134.
Ensure Consistency with Federal Regulations
Additionally, the proposed rules adopt changes to the most current EPA methods for measuring air pollutant emissions (stack testing and continuous monitoring), the revised definition of “volatile organic compounds” (also known as “VOC”), and updated federal modeling guidelines used for the Prevention of Significant Deterioration (PSD) program. The proposal also includes adoption of revisions to federal new source performance standards (NSPS) and air toxics standards (also known as National Emissions Standard for Hazardous Air Pollutants or NESHAP). Adopting EPA’s amendments allows state rules to be consistent with federal regulations and provides certainty to affected businesses and other interested stakeholders.

March 25, 2020
The Iowa Department of Natural Resources - Air Quality Bureau (Iowa DNR) invites the public to provide informal comments on updates to the dispersion modeling guidance.
The DNR is proposing to update four modeling guidance documents based on new EPA guidance and revisions to EPA modeling requirements found in Appendix W (40 CFR Part 51). The dispersion modeling guidance updates include modifications to incorporate EPA's latest guidance on ambient air and secondary air pollutant formation and provides revised guidance on NOx modeling techniques.
Incorporation of EPA's latest modeling guidance and requirements into DNR's modeling guidance documents will align DNR's modeling guidance with EPA's latest changes and will not result in new or increased modeling requirements on Iowa facilities.
The updated guidance incorporates the newest EPA ambient air guidance.
The updated guidance includes the Model Emission Rates for Precursors guidance and the Appendix W two tier approach to secondary formatin of PM2.5 and ozone.
NOx Modeling Techniques
The updated guidance removes the use of the Ambient Ratio Method (ARM) as a NOx modeling technique per Appendix W revisions.
How to Provide Input
Written comments on the updates to the dispersion modeling guidance should be provided to Alyssa Fizel by Friday April 10, 2020 at Alyssa.Fizel@dnr.iowa.gov or by mail to the Iowa DNR at 502 E 9th Street, Des Moines, Iowa 50319.
The draft modeling guidance is available on the DNR's Air Quality Public Participation website or at www.iowadnr.gov/airpublicinput under the Public Input section.
For more information, please contact Alyssa Fizel by email at Alyssa.Fizel@dnr.iowa.gov or by phone at 515-725-9566.

Five-year Air Monitoring Assessment - Part 2
The Air Quality Bureau must receive all public comments by April 30, 2020.
Comments may be sent by electronic mail to Sean.Fitzsimmons@dnr.iowa.gov.
Please include "5-year Air Monitoring Network Assessment" in the subject line of the e-mail.
Air Quality Client Contact Meetings focus on current and upcoming air program issues and changes. The meetings provide an open forum for stakeholders and the general public to discuss new state and federal air quality rules or air program developments and are a good source of information for anyone who works with or has an interest in activities related to air quality.
All meetings are open to the public.
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 Jim McGraw at Jim.Mcgraw@dnr.iowa.gov or
Major Source Construction Permit Application Fee and Title V Fees Advisory Group
Minor Source Construction Permit Application Fee Advisory Group
Asbestos Notification Fee Advisory Group
The Air Quality Bureau convened a diverse work group (see members below) to reexamine and provide feedback on the current fees for: minor source and major source air construction permit applications; operating permit applications; Title V emissions; and asbestos notifications. Group members developed and endorsed specific recommendations for future changes to funding the Iowa air quality program.

July 7 enfoTech eApplication Presentation
The DNR held a Value Stream Mapping Event (VSM) on October 17 – 20, 2016. This was a collaborative event with six industry representatives and was co-facilitated by the Department of Management. The VSM participants thoroughly discussed various opportunities to transform Title V permitting and came to consensus on six key deliverables to improve efficiency:
These deliverables will relate to receiving better information from our applicants, thereby improving the efficiency of the DNR staff who will no longer spend time collecting information that could have been provided up front.
Since three of these improvements are more complex in nature the DNR is asking for the input of additional team members. Two workgroups will be held between January 17 and 20, 2017 to address the optional pre-meetings and improvements to the application forms. If you are interested in participating in either one or both workgroups, or for additional information, contact Lori Hanson. The workgroups will consist of a diverse group of twelve to fifteen industry representatives.
If you have comments or questions about the VSM event or wish to participate in the upcoming workgroups, please contact Lori Hanson, Title V Permit Supervisor, at 515-725-9525 or Lori.Hanson@dnr.iowa.gov.
Title V Workgroups
Representatives from eight businesses collaborated with Title V permit writing staff from the DNR and Linn County in two workgroups held between January 17 and 20, 2017. One team addressed optional pre-meetings for hands-on help with the application, likely resulting in a faster application review time a permit that better reflects the needs of the business. The second team simplified the Title V application forms by creating Excel spreadsheet versions of some forms, allowing the use of previous versions of the forms, reducing the information requested, and updating the application instructions.
The purpose of the eAirServices Advisory Workgroup is to provide recommendations to the DNR related to the current and future operations of SLEIS, SPARS, and e-Application.
Please contact Jim McGraw at Jim.McGraw@dnr.iowa.gov or at 515-725-9543 if you have any questions.
