Description:  TITLE: National Emission Standards for Hazardous Air Pollutants for Major Sources: 
Industrial, Commercial, and Institutional Boilers and Process Heaters  
AGENCY: Environmental Protection Agency (EPA)  
ACTION: Final rule  
SUMMARY: This action finalizes amendments to the national emission standards for hazardous air 
pollutants (NESHAP) at major sources f rom new and existing industrial, commercial, and institutional

  for new and existing boilers and process heaters consistent with the court's opinion and sets 
compliance dates for these new emission limits. This action also provi des further explanation of one 
aspect of the Agency's use of carbon monoxide (CO) as a surrogate for organic hazardous air 
pollutants (HAP) and its use of a CO threshold to represent the application of the maximum 
achievable control technology (MACT) for o rganic HAP. We are also finalizing several technical 
clarifications and corrections.
