326 IAC 11-7-3 Emission limits

Sec. 3. The concentration of pollutants contained in the gases discharged to the atmosphere from a designated facility shall not exceed the following limits: Pollutant Emission Limits Particulate matter 25 milligrams per dry standard cubic meter (mg/dscm)1 Opacity 10% based on a 6-minute average Cadmium 0.035 mg/dscm1 Lead 0.400 mg/dscm1 Mercury 0.050 mg/dscm; or 15% of the potential mercury emissions concentration1,3 Sulfur dioxide 29 parts per million by volume (ppmv); or 20% of the potential sulfur dioxide emission concentration3,4 Hydrogen chloride 29 ppmv; or 5% of the potential hydrogen chloride emissions concentration2,3 Organic emission (expressed as total mass dioxins/furans) 30 nanograms per dry standard cubic meter (ng/dscm) total mass1 Nitrogen oxides 205 ppmv2 Carbon monoxide5 100 ppmv5 (based on a 4-hour block averaging time) 1Corrected to seven percent (7%) oxygen. 2Corrected to seven percent (7%) oxygen, dry basis. 3Whichever concentration is less stringent. 4Corrected to seven percent (7%) oxygen, dry basis, calculated as a 24-hour daily geometric mean. 5Measured at the combustor outlet in conjunction with a measurement of oxygen concentration, corrected to seven percent (7%) oxygen, dry basis, calculated as an arithmetic mean.
