Complying with EPA Boiler Regulations


The EPA works with its federal, state and tribal regulatory partners to monitor and ensure compliance with clean air laws and regulations in order to protect human health and the environment. The Clean Air Act is the primary federal law governing air pollution.

Understand and Comply with Area Source Boiler and Major Source Boiler Rules from the EPA

A Major Source facility emits 10 or more tons per year of any single air toxic or 25 tons or more per year of any combination of air toxins. A comprehensive list of the regulated air toxics can be found on the EPA website. If your facility does not meet the criteria for a Major Source, it is considered an Area Source. 

Area Source Boiler Rules

Area Source facilities typically include: stores and malls, laundries, apartments, restaurants, hotels and motels, hospitals, clinics, nursing homes, schools, churches, amusement parks, courthouses, prisons, and small manufacturing plants.

Understand and comply with industrial, commercial and Institutional Area Source Boilers for National Emission Standards for Hazardous Air Pollutants.

Major Source Boiler Rules

Major Source facilities typically include: large industrial facilities (such as refineries, chemical plants, and large manufacturing plants), and large institutional facilities (such as universities). 

To understand and comply with Industrial, Commercial, and Institutional Boilers and Process Heaters: National Emission Standards for Hazardous Air Pollutants (NESHAP) for Major Sources for National Emission Standards for Hazardous Air Pollutants.
