EPA Rules for Boilers are In Effect

THOMASVILLE, Ga:  May 14, 2013

First Deadline for Major Source Facilities is May 31, 2013  


Facilities are required to meet EPA’s finalized regulations for boilers under the Area Source Rule or Major Source Rule (also known as the Boiler MACT or BMACT), published in the Federal Register on February 1, 2013 and January 31, 2013, respectively. The first requirement is for facilities to complete an Initial Notification of Applicability. The deadline for major source boilers to submit this form is May 31, 2013, and the deadline for area source boilers is January 20, 2014. For instructions and a form template, visit the  Cleaver-Brooks EPA Compliance Center for Boilers .

The Major Source Rule applies to facilities that emit 10 or more tons per year of any single air toxic or 25 tons or more per year of any combination of air toxics. Most major source boilers are located at very large industrial facilities (such as refineries, chemical plants and large manufacturing plants), and large institutional facilities (such as universities). If a facility does not meet the criteria for a major source, it is considered an area source and is subject to the Area Source Rule. 

Under both rules, there are required actions ranging from regular tune-ups to emissions monitoring. Facilities also must maintain records and file periodic reports to demonstrate compliance. The extent of actions and the number of reports to be filed vary depending upon boiler size, fuel type and age. Under both rules, boilers are considered new sources if they commenced construction or reconstruction after June 4, 2010.


Area Source Rule Requirements 

Under the Area Source Rule, existing sources must comply with the following requirements by March 21, 2014. New boilers must comply upon startup.

Tune-ups are required for boilers that burn oil, biomass or coal, with varying frequency for different fuel types and designs. The rule establishes guidelines for the tune-up, which are more encompassing than a typical industry tune-up.

  • Biomass-fueled units, coal-fired units and oil-fired units with a heat input capacity of greater than 5 MMBTU/hr are required to conduct a tune-up biennially. 
  • Seasonal and limited-use units, oil-fired units with a heat input capacity of less than or equal to 5 MMBTU/hr, and units with an oxygen trim system require a tune-up every five years. 

A one-time energy assessment is required for all existing large boilers with a heat input capacity equal to or greater than 10 MMBTU/hr, except limited-use units.  

Emissions limits are required for boilers with a heat input capacity equal to or greater than 10 MMBTU/hr that burn coal (both new and existing units), biomass (new units only), or oil (new units only).

  • New coal-fired boilers must adhere to limits on mercury, carbon monoxide and filterable particulate. Existing coal-fired boilers are subject only to limits on carbon monoxide and mercury. 
  • New oil-fired and biomass-fired units must meet limits on filterable particulate matter. 
  • Limited-use boilers are exempt from meeting emissions requirements. 

For boilers with a heat input capacity equal to or greater than 10 MMBTU/hr, a performance test must be conducted every three years.  

Major Source (Boiler MACT) Rule Requirements 

Existing boilers must comply with the following requirements by January 31, 2016. New boilers must comply upon startup.

Tune-ups are required for most boilers, with varying frequency for different fuel types and designs. The rule establishes guidelines for the tune-up, which are more encompassing than a typical industry tune-up.

  • Annual tune-ups are required for boilers with a heat input capacity equal to or greater than 10 MMBTU/hr that are not equipped with an oxygen trim system.  
  • Biennial tune-ups are required for boilers fueled by heavy liquid or by solid fuel and  have a heat input capacity of less than 10 MMBTU/hr, as well as for boilers fueled by gas or light liquid that have a heat input capacity of 5 – 10 MMBTU/hr and are not equipped with an oxygen trim system. 
  • Tune-ups are required every five years for new and existing boilers that burn natural gas or light liquid fuel and have a heat input capacity of less than or equal to 5 MMBTU/hr, or units that have an oxygen trim system, as well as limited-use boilers. 

 A one-time energy assessment is required for all existing boilers except limited-use units. 

 Emissions limit requirements vary depending upon fuel type and size: 

  • For boilers that burn solid fuels (coal or biomass), EPA has imposed emissions limits with 13 different variations for different boiler configurations and fuel types, limiting carbon monoxide, mercury, hydrogen chloride as a surrogate for acid gases, and filterable particulate matter (or alternatively, total suspended metals).  
  • For oil-fired boilers, the rule limits the same air pollutants but differentiates between boilers fueled by light oil and heavy oil for the limits on filterable particulate matter and carbon monoxide. 

Annual performance tests are required for units subject to emissions limits. Performance can be demonstrated by a monthly fuel analysis, rather than by conducting an annual emissions test, for chloride, mercury and total suspended metals.
