The emissions reporting rule, 326 IAC 2-6, requires air emission sources over emission thresholds* to report their actual emissions of certain pollutants to the department annually or triennially. The information is used for a variety of purposes including planning, trends analysis, modeling, and billing.
The list below provides links to the emissions information the state as a whole. Each page contains the facility's name, plant ID and reported criteria pollutant emissions. The criteria pollutants are Volatile Organic Compounds (VOC), Carbon Monoxide (CO), Nitrogen Oxides (NO2), Sulfur Dioxide (SO2), and Particulate Matter less than 10 microns in diameter (PM10). If you have any questions regarding emissions reporting contact OAQ staff.
Please Note: All emissions are in tons per year.
