227-2.4 Control requirements.
(a) Very large boilers.
The owner or operator of a very large boiler must comply with either the relevant presumptive RACT emission limit of paragraph (1) of this subdivision or a case-by-case RACT determination made pursuant to paragraph (2) of this subdivision, as applicable.
(1) Emission limits (pounds NOx per million Btu):
| Tangential | Wall | Cyclone | Fluidized Bed | |
|---|---|---|---|---|
| Fuel Type | ||||
| Gas Only | 0.08 | 0.08 | na | na |
| Gas/Oil | 0.15 | 0.15 | 0.20 | na |
| Coal Wet Bottom | 0.12 | 0.12 | 0.20 | na |
| Coal Dry Bottom | 0.12 | 0.12 | na | 0.08 |
(2) For very large boilers having configurations other than those listed above or which are fired primarily with fuels not listed above, the owner or operator must submit a case-by-case RACT analysis.
(b) Large boilers.
The owner or operator of a large boiler must comply with either the relevant presumptive RACT emission limit of paragraph (1) of this subdivision or a case-by-case RACT determination made pursuant to paragraph (2) of this subdivision, as applicable.
(1) Emission limits (pounds NOx per million Btu):
| Fuel Type | Emission Limit |
|---|---|
| Gas Only | 0.06 |
| Gas/Oil | 0.15 |
| Pulverized Coal | 0.20 |
| Coal | 0.081 |
1
This emission limit also applies to fluidized bed boilers that combust other solid fuels (for example, tire-derived fuel, waste wood) that constitute no more than 30 percent of the total fuel content on a Btu basis.
(2) For large boilers fired primarily with fuels not listed above, the owner or operator must submit a case-by-case RACT analysis.
(c) Mid-size boilers.
The owner or operator of a mid-size boiler must comply with the relevant presumptive RACT emission limit of paragraph (1) of this subdivision or a case-by-case RACT determination pursuant to paragraph (2) of this subdivision, as applicable.
(1) Emission limits (pounds NOx per million Btu):
| Fuel Type | Emission Limit |
|---|---|
| Gas Only | 0.05 |
| Distillate Oil/Gas | 0.08 |
| Residual Oil/Gas | 0.20 |
(2) For mid-size boilers fired primarily with fuels not listed above, the owner or operator must submit a case-by-case RACT analysis.
(d) Small boilers, small combustion turbines, and small stationary internal combustion engines.
The owner or operator of a small boiler, small combustion turbine, or small stationary internal combustion engine must annually perform a tune-up and maintain, in a permanently bound log book, or other format approved in writing by the department, the following information:
(1) the date of the last tune-up;
(2) the name, title, and affiliation of the person who made the adjustments; and
(3) any other information that the department may require.
(e) Combustion turbines.
The owner or operator of a combustion turbine with a maximum heat input rate of 10 million Btu per hour or greater must comply with either the relevant presumptive RACT emission limit in paragraph (1) or (2) of this subdivision, as applicable:
(1) For simple cycle and regenerative combustion turbines:
(i) 50 parts per million on a dry volume basis (ppmvd), corrected to 15 percent oxygen, for sources designed to burn gaseous fuels (gaseous fuels include, but are not limited to, natural gas, landfill gas, and digester gas) only; and
(ii) 100 ppmvd, corrected to 15 percent oxygen, for sources designed to burn distillate oil alone or in combination with other fuels (gaseous or liquid).
(2) For combined cycle combustion turbines, the owner or operator must submit a case-by-case RACT analysis upon the submission of either a new or renewal application for a title V permit.
For facilities that have a duct burner, compliance will be based on the combination of the turbine and the duct burner when both fire, and the turbine alone when not duct-firing.
(f) Stationary internal combustion engines.
The owner or operator of a stationary internal combustion engine either having a maximum mechanical output rating equal to or greater than 200 brake horsepower in a severe ozone nonattainment area or having a maximum mechanical output rating equal to or greater than 400 brake horsepower outside a severe ozone nonattainment area must comply with one of the emission limits in paragraph (1), (2), or (3) of this subdivision or a case-by-case RACT determination made pursuant to paragraph (4) of this subdivision, as applicable:
(1) For internal combustion engines fired solely with natural gas: 1.5 grams per brake horsepower-hour.
(2) For internal combustion engines fired with landfill gas or digester gas (solely or in combination with natural gas): 2.0 grams per brake horsepower-hour.
(3) For internal combustion engine fired with distillate oil (solely or in combination with other fuels): 2.3 grams per brake horsepower-hour.
(4) For stationary internal combustion engines fired primarily with fuels not listed above, the owner or operator must submit a case-by-case RACT analysis.
(5) Any stationary internal combustion engine may rely on an emission limit that reflects a 90 percent or greater NOx reduction from the engine's actual 1990 baseline emissions, if such emissions baseline exists.
(6) Emergency power generating stationary internal combustion engines, and engine test cells at engine manufacturing facilities that are used for either research and development purposes, reliability testing, or quality assurance performance testing are exempt from the requirements of this subdivision.
(g) Other combustion installations.
The owner or operator of a major facility of NOx that contains an emission source that is not specifically addressed in this Subpart and is of an emission source type not regulated under Part 212, 214, 216, 219, 220, or 224 of this Title and which has an emission rate potential of at least 3 pounds per hour and actual emissions in the absence of control equipment of at least 15 pounds per day must comply with the case-by-case RACT determination made pursuant to this subdivision. The owner or operator must submit a case-by-case RACT analysis.

This emission limit also applies to fluidized bed boilers that combust other solid fuels (for example, tire-derived fuel, waste wood) that constitute no more than 30 percent of the total fuel content on a Btu basis.
