The EPA has enacted new rules regarding boiler operations which impact your operations for 2012 and years beyond. The rules are complex and affect all boilers and fuels used. Consider this document as a summary of primary rules for boilers firing natural gas, oil and propane. If you are firing coal or at least 15% biomass, we suggest that you consult the EPA website for further requirements.

Boiler size and age are as follows:

• Boiler size, as it relates to the Area Source Rule, is expressed in terms of rated design heat input capacity and is measured in million British thermal units per hour, or MMBTU/hr. Boilers that are larger or equal to 10 million BTU/HR input have different requirements than those that are smaller than 10 million BTU/HR. As a rule of thumb, typically boilers in the 225-230 BHP range are less than 10 million BTU/HR input. Check the name plate on your boiler if you are not sure. It will show the gross input for natural gas and oil if it is used.

• Boilers divided into two age groups and defined as an existing boiler or new boiler. Definitions are an existing source if construction or reconstruction began on or before June 4, 2010. A boiler is considered a new source if construction or reconstruction began after June 4, 2010, and the applicability criteria was met when construction started, or the boiler switched from firing natural gas fuel to a liquid fuel after June 4, 2010. General Requirements

• Gas-fired -- any boiler that burns gaseous fuels, including: natural gas, process gas, landfill gas, coal-derived gas, refinery gas, hydrogen, or biogas, not combined with any solid fuels. To maintain status as a gas-fired boiler, periodic burning of a liquid fuel cannot exceed a combined total of 48 hours during any calendar year.

• Oil -- any boiler that burns any liquid fuel and is not in either the biomass or coal subcategories.

• Fuel usage must be metered and recorded monthly.

If you fire oil in your boiler more than 48 hours during any calendar year independent of boiler size, an annual boiler tune up is required with the first tune up being completed by March 12, 2012. Tune-ups are then required once each calendar year after 2012.

For the initial tune-up, the following steps are necessary:

• Inspect the burner and clean or replace any components, as necessary.

• Adjust the burner as necessary to optimize the flame pattern.

• Inspect air-to-fuel ratio control system to ensure system is calibrated and functioning properly.

• Optimize emissions of carbon monoxide (CO) consistent with manufacturer’s specifications, if available.

• Measure CO and O2 levels in exhaust before and after tune-up.

• Record the type and amount of fuel used for previous 12 months (the effective date of the rule was May 20, 2011, so the first tune-up will have less than 12 months of reporting).

• Submit a signed statement indicating that a boiler tune-up was completed.

The same steps are required for subsequent tune-ups. The compliance certificates should be kept at the facility and submitted upon request.
