Assume this boiler isn't required to have a permit under section 3005 of the Solid Waste Disposal Act or covered by subpart EEE of this part (e.g., hazardous waste boilers) [exempt under § 63.11195(c)]
 | 1. Own or operate a boiler to provide steam, hot water, and/or electricity (a collection of all existing boilers within a subcategory or each new or reconstructed boiler)
 | 2. Located at, or is part of, an area source of HAP
 |  | 2A. Not an affected source if boilers that are subject to another standard under 40 CFR part 63 or to a standard developed under CAA section 129.
 |  | 2B. Not used specifically for R&D (does not include boilers that solely or primarily provide steam (or heat) to a process or for heating at a R&D facility).
 |  | 2C. Not a hot water heater (i.e., closed vessel with a capacity less than or equal to 120 U.S. gallons in which water is heated by combustion of gaseous or liquid fuel; water shall not be withdrawn at pressures exceeding 160 psig, including the apparatus to prevent water temperatures from exceeding 210 degrees Fahrenheit).
missing waste heat and haz waste should go here |  | 2D. Not a control device to comply with another subpart of this part; at least 50 percent of the heat input to the boiler is provided by by a gas stream that is regulated under another subpart.
 | 3. Is your boiler gaseous-fired (i.e., not combination of solid fuels and burns liquid fuel only for periodic testing not to exceede 48-hrs/yr).
 | GO TO ROW # 1
 | 4.  Existing source if you commenced construction or reconstruction on or before June 4, 2010.
 |  | 4A.Is your boilers designed heat input capacity LESS than 10 MMBtu/hr?
 |  | GO TO ROW # 2
 |  | 4B. If your boiler burns at least 15 percent biomass on a total fuel annual heat input basis, the unit is in the biomass subcategory.
 |  | GO TO ROW # 3
 |  | 4C. If your boiler burns any solid fossil fuel and no more than 15 percent biomass on a total fuel annual heat input basis, the boiler is in the coal subcategory.
 |  | IF NO, GO TO ROW # 4   (i.e., boiler burns any liquid fuel and is not in either the coal or the biomass subcategory, the unit is in the oil subcategory, except if the unit burns oil only during periods of gas curtailment)
 |  | IF YES, GO TO ROW # 5
 | 5. New source if you commenced construction or reconstruction OR switched from natural gas fuel to solid fossil fuel, biomass, or liquid fuel after June 4, 2010.
 |  | 5A. Is your boilers designed heat input capacity LESS than 10 MMBtu/hr?
 |  | GO TO ROW # 6
 |  | 5B. If your boiler burns any solid fossil fuel and no more than 15 percent biomass on a total fuel annual heat input basis, the boiler is in the coal subcategory.
 |  | GO TO ROW # 8
 |  | 5C. If your boiler burns at least 15 percent biomass on a total fuel annual heat input basis, the unit is in the biomass subcategory.
 |  | IF YES, GO TO ROW # 7
 |  | IF NO, GO TO ROW # 9   (i.e., boiler burns any liquid fuel and is not in either the coal or the biomass subcategory, the unit is in the oil subcategory, except if the unit burns oil only during periods of gas curtailment)
