June 9, 2020
Open Table
| For the following municipal waste combustion units | You must meet the following carbon monoxide limitsa | Using the following averaging timesb |
|---|---|---|
| 1. Fluidized bed | 100 parts per million by dry volume | 4-hour. |
| 2. Fluidized bed, mixed fuel, (wood/refuse-derived fuel) | 200 parts per million by dry volume | 24-hourc. |
| 3. Mass burn rotary refractory | 100 parts per million by dry volume | 4-hour. |
| 4. Mass burn rotary waterwall | 250 parts per million by dry volume | 24-hour. |
| 5. Mass burn waterwall and refractory | 100 parts per million by dry volume | 4-hour. |
| 6. Mixed fuel-fired, (pulverized coal/refuse-derived fuel) | 150 parts per million by dry volume | 4-hour. |
| 7. Modular starved-air and excess air | 50 parts per million by dry volume | 4-hour. |
| 8. Spreader stoker, mixed fuel-fired (coal/refuse-derived fuel) | 200 parts per million by dry volume | 24-hour daily. |
| 9. Stoker, refuse-derived fuel | 200 parts per million by dry volume | 24-hour daily. |
aAll emission limits (except for opacity) are measured at 7 percent oxygen. Compliance is determined by continuous emission monitoring systems.
bBlock averages, arithmetic mean. See §60.1940 for definitions.
c24-hour block average, geometric mean.
