Operating Permits (Title V)



General Information

The Federal Title V Operating Permit Program applies to major sources of air emissions; however, the Iowa Department of Natural Resources (DNR) issues all Title V Permits in Linn County. Therefore, all rules, policies, and application materials issued by the DNR are used. These materials are available on the DNR Operating Permits website.

Facilities are subject to the Federal Title V Operating Permit Program if they emit more than 99.4 tons per year of any single criteria pollutant, 9.4 tons per year of any single hazardous air pollutant (HAP), or 24.4 tons per year of combined HAPs. In addition, facilities subject to certain New Source Performance Standards or National Emission Standards for Hazardous Air Pollutants may be required to apply for a Title V Operating Permit to comply with those requirements. Once a facility becomes subject to the program, they have 12 months to prepare and submit a Title V Operating Permit application to the DNR. Title V Operating Permit applications are subject to review fees according to the DNR Air Quality Fee Schedule.

Changes to Public Notice Effective April 18, 2018

Draft Title V Operating Permits are publicly available for review and comment from the DNR and the Linn County Air Quality Branch. As of April 18, 2018, the DNR now provides online publication of public notice for these draft permits in lieu of print publications. All draft Title V Operating Permit public notices will be disseminated through their EcoNewsWire, which is published every Thursday.
