Boiler Type - The rule applies to oil, coal and other fuel, and biomass, but NOT to gas-fired boilers.
Obligation - Requirements vary depending on the size of your boiler and whether it is existing or new. Boilers greater than or equal to 10,000,000 BTU/hr are classified as LARGE boilers, less than 10,000,000 BTU/hr are classifed as SMALL boilers.
Initial Notification - For existing boilers of any size (that are NOT natural gas-fired), you must submit an initial notification form to EPA by September 17, 2011.
Limits - Emission limits only apply to existing LARGE boilers fired by coal and biomass and new coal-fired boilers.
Energy Assessments - are only required one-time for LARGE coal and biomass fired boilers.
Recordkeeping should be kept on-site to demonstrate you are up-to-date with any applicable requirements such as tune-ups and the fuel used by the boiler.
