| Municipal Waste Combustion Technology | Limits for Class I Municipal Waste Combustion Units |
|---|---|
| 1. Mass burn waterwall | 200 parts per million by dry volume |
| 2. Mass burn rotary waterwall | 170 parts per million by dry volume |
| 3. Refuse-derived fuel | 250 parts per million by dry volume |
| 4. Fluidized bed | 220 parts per million by dry volume |
| 5. Mass burn refractory | 350 parts per million by dry volume |
| 6. Modular excess air | 190 parts per million by dry volume |
| 7. Modular starved air | 380 parts per million by dry volume |
aClass I units mean small municipal waste combustion units subject to this division that are located at municipal waste combustion plants with an aggregate plant combustion capacity greater than 250 tons per day of municipal solid waste. See §113.2100 of this title for definitions.
bNitrogen oxides limits are measured at 7 percent oxygen.
cAll limits are 24-hour daily block arithmetic average concentration. Compliance is determined for Class I units by continuous emission monitoring systems.
