Air Quality in Indiana

Air Quality in Indiana > Permits Permits

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.
