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) |
1 Corrected to seven percent (7%) oxygen.
2 Corrected to seven percent (7%) oxygen, dry basis.
3 Whichever concentration is less stringent.
4 Corrected to seven percent (7%) oxygen, dry basis, calculated as a 24-hour daily geometric mean.
5 Measured 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.
