Emissions Standards for Boilers and Process Heaters and Commercial / Industrial Solid Waste Incinerators
Basic Information
Section 129 of the Clean Air Act requires emissions standards for 9 pollutants from incinerators including Commercial/Industrial Solid Waste Incinerators (CISWI). Large and smaller sources are treated in the same way.
- The nine pollutants include: Cadmium, Carbon Monoxide, Dioxins/Furans, Hydrogen Chloride, Lead, Mercury, Oxides of Nitrogen, Particulate Matter, and Sulfur Dioxide
Section 112 of the Clean Air Act requires emissions standards for boilers and process heaters.
- Major sources emit 10 tons of any one toxic air pollutant or 25 tons of all toxic air pollutants each year.
- Emissions standards based on the maximum achievable control technology (MACT) must be set for all emitted toxic air pollutants
- Area sources are smaller and may be regulated based on less stringent generally available control technology (GACT)
- Exception for certain pollutants (e.g., mercury, polycyclic organic matter), which must have MACT standards.
