IDEM > Reporting > Emissions Reporting Emissions Reporting

The Technical Support & Modeling Section collects and compiles air emissions data reported by companies. Many Indiana companies are required to report emissions data by the Emission Reporting rule (326 IAC 2-6). An emissions statement contains the amounts of nitrogen oxides, volatile organic compounds, sulfur dioxide, carbon monoxide, particulate matter that is 10 microns or smaller, and lead released to the air each year. The Office of Air Quality uses the reported emissions for many purposes including air quality planning and to calculate fees for Title V permits (Part 70 Permit Program, 326 IAC 2-7).
