If your business operations produce waste gasses or particles that are released to the air, you may need some type of permit from IDEM's Office of Air Quality. The level of permit required depends on your potential emissions. Visit the links here to learn about the various air permit programs managed by IDEM, and please contact our staff to discuss your specific plans for details about permitting requirements. Working with IDEM to obtain the correct permit will help you stay in compliance with environmental regulations. Failing to apply for an IDEM permit, or operating without the correct type of permit, are violations.

Indiana Air Permit Fee Increases for the Title V Program
On August 14, 2019, the Indiana Environmental Rules Board affirmed a decision by the Indiana Department of Environmental Management (IDEM) Commissioner to increase the Office of Air Quality (OAQ) Title V program fees by 27%. IDEM presented the following report to the Board on August 14, 2019, demonstrating the need for increases to the Title V program fees:
Title V program fees include all fees from Part 70 sources under 326 IAC 2-7, FESOP sources under 326 IAC 2-8, and SSOA sources under 326 IAC 2-9. Increases to annual fees for these sources will be reflected on the annual fee invoice to be sent out in January 2020. Increases to other Title V program fees will be applied to applications postmarked on and after October 1, 2019. A rulemaking is in process to update the Title V program fees in 326 IAC 2-1.1-7.

Fees associated with other sources in the state (MSOP, Registrations, Exemptions, Permit by Rule) are not affected by this action and will not change.
