Industrial, Commercial, and Institutional Area Source Boilers: National Emission Standards for Hazardous Air Pollutants (NESHAP)

Rule Summary

On March 21, 2011, EPA issued final emission standards to reduce emissions of toxic air pollutants from industrial, commercial, and institutional boilers located at area source facilities.  An area source facility emits or has the potential to emit less than 10 tons per year of any single air toxic or less than 25 tons per year of any combination of air toxics.  The final rule covers boilers located at area source facilities that burn coal, oil, or biomass, but not boilers that burn only gaseous fuels or any solid waste.  The rule establishes standards to address emissions of mercury, particulate matter (as a surrogate for non-mercury metals), and carbon monoxide (as a surrogate for organic air toxics).
