EPA Area Source Boiler MACT Notification Due 1

Facilities that meet the applicability criteria of the EPA’s National Emission Standards for Industrial/Commercial/Institutional Boilers at Area Sources (40 CFR 63, Subpart JJJJJJ) are required to submit an initial notification with the EPA no later than September 17, 2011.

Does it apply to your Boilers?

The rule applies to all boilers located at area sources, with the exception of gas fired boilers and hot water heaters. An area source is any facility that emits less than 10 tons per year of any single hazardous air pollutant (HAP), and less than 25 tons per year of any combination of HAPS.

The EPA offers the following definitions for exempt sources:

Gas-fired boiler includes any boiler that burns gaseous fuels not combined with any solid fuels, burns liquid fuel only during periods of gas curtailment, gas supply emergencies, or periodic testing on liquid fuel. Periodic testing of liquid fuel shall not exceed a combined total of 48 hours during any calendar year.

Liquid fuel means, but not limited to, petroleum, distillate oil, residual oil, any form of liquid fuel derived from petroleum, used oil, liquid biofuels, and biodiesel.

Hot water heater means a closed vessel with a capacity of no more than 120 U.S. gallons in which water is heated by combustion of gaseous or liquid fuel and is withdrawn for use external to the vessel at pressures not exceeding 160 pounds per square inch gauge (psig, including the apparatus by which the heat is generated and all controls and devices necessary to prevent water temperatures from exceeding 210 degrees Fahrenheit (99 degrees Celsius).

What are your requirements?

In addition to the requirement to file an initial notification, the regulation also contains requirements related to emission limits, work practice standards, operating limits (for sources with emission limits), and reporting. The exact requirements for any particular boiler are based on whether the boiler is existing or new, what the heat input rating is for the boiler, and what type of fuel is combusted (biomass, oil, or coal). A boiler is an existing unit if it commenced construction on or before June 4, 2010. A boiler is a new unit if it commenced construction after June 4, 2010.

Below is a summary of some of the key compliance dates:

• By September 17, 2011 – File an initial notification of applicability with the EPA.

• By September 17, 2011 – New boilers must file the notification, or within 120 days of startup, whichever is later. An example notification form can be found on the EPA website at the following address:

• By March 21, 2012 – All boilers (except coal fired units greater than 10 MMBtu/hr) must have their first biennial tune-up conducted. Subsequent tune-ups must be completed no later than 25 months after the previous tune-up.

• By July 19, 2012 – All existing boilers (except coal fired units greater than 10 MMBtu/hr – See regulation for applicable dates) must file a notice of compliance status with EPA.

• By March 21, 2014 – All existing boilers with heat input ratings of 10 MMBtu/hr or greater must perform a one-time energy assessment. New boilers are not required to conduct energy assessments.

The above is just a summary of the major requirements. For a complete listing of all requirements that might apply to your boiler, you should consult 40 CFR 63, Subpart JJJJJJ. A copy of the final regulation as published on March 21, 2011 can be found on the EPA website at the following address:

  1. Great summary. Cleaver-Brooks has also developed tools and tips to help boiler owners understand their registration and reporting requirements, including a simple decision tree. For more information visit http://bit.ly/r9Ub24
