Air Quality

One of the many responsibilities of the Indiana Department of Environmental Management (IDEM) is to protect the quality of Indiana’s air. This responsibility couldn’t be more important because air quality, or the lack of it, impacts the health of every person in our state every minute of every day. Good air quality helps us live our lives with vitality and energy. Poor air quality can cause harm to living things that are exposed to it.

The Clean Air Act (CAA) of 1970 began years of air quality improvement in our country. Health-based national ambient air quality standards (NAAQS) have been and continue to be the foundation of the CAA. These standards are maximum measurements allowed in our air by law, for each pollutant covered by the CAA. IDEM was established in 1986 to assist people and businesses located in Indiana to keep the air in Indiana at or below those standards. The following options offer access to more about how IDEM works to improve the air quality in Indiana.

Indiana Air Permit Fee Information and Request for Fee Increases for Title V Permit Fees

IDEM’s Office of Air Quality has completed an extensive evaluation of revenues from Title V permit fees, and after careful consideration, and consistent with the provisions of the Indiana General Assembly’s House Enrolled Act 1278 which directs the Environmental Rules Board to approve a fee increase, IDEM is proposing to increase Title V permit fees. This proposed increase is necessary so that IDEM can continue to provide quality permit service in the air program and to ensure that IDEM has sufficient revenue to maintain the other portions of the air program funded through Title V fees.
