Appendix D - Emissions Limits for Large MWC Units

Pollutant or Parameter	Emission Limit	Averaging Time
Particulate matter	25 milligrams (mg)/dry standard cubic meter (dscm), corrected to 7 % oxygen	3-run average (run duration specified in test method)
Opacity	10 percent (6-minute average)	30 6-minute averages
Cadmium	0.035 mg/dscm, corrected to 7 % oxygen	3-run average (run duration specified in test method)
Lead	0.40 mg/dscm, corrected to 7 % oxygen	3-run average (run duration specified in test method)
Mercury	0.028 mg/dscm, corrected to 7 % oxygen, or 85 % control efficiency	3-run average (run duration specified in test method)
Sulfur dioxide	29 parts per million by volume (ppmv), or 25 % of the potential sulfur dioxide emission concentration, corrected to 7 % oxygen (dry basis)	24-hour daily block geometric average concentration or percent reduction
Hydrogen chloride	29 ppmv, or 5 % of the potential hydrogen chloride emission concentration, corrected to 7 % oxygen (dry basis)	3-run average (minimum run duration is 1 hour)
Dioxins/furans	35 nanograms/dscm (total mass), corrected to 7% oxygen, where an electrostatic precipitator-based emission control system is employed; or 30 nanograms/dscm (total mass) corrected to 7% oxygen, where an electrostatic precipitator-based emission control system is not employed	3-run average (minimum run duration is 4 hours)
