What Comes Out of a Coal Plant?

█ Sulfur Dioxide

█ Nitrogen Oxides

█ Carbon Monoxide

█ Volatile Organic Compounds

█ Hazardous Air Pollutants

█ (Carbon Dioxide)

█ Particulate Matter

How is a Coal-fired Power Plant Regulated for PM Emissions?

█ Specific PM emission stack limits

█ Opacity limits

█ Fugitive dust limits

█ Other emission limits

PM Stack Emission Limits

█ Set on a pounds per million BTUs basis

█ Includes PM10 and PM 2.5

█ NSPS limits:

█ .03 lb/mmBTU

█ BACT may reduce limit further

█ Large unit (500 - 600 MW) emits about 500 tpy (controlled)

Opacity Limits

█ NSPS: 20% opacity
