9VAC5-40-6580: Standard for carbon monoxide

No owner or other person shall cause or permit to be discharged into the atmosphere from any small municipal waste combustion unit any carbon monoxide emissions in excess of the following.

1. For fluidized bed units: 100 parts per million by dry volume, measured at 7.0% oxygen, four-hour block average, arithmetic mean.

2. For fluidized bed, mixed fuel (wood/refuse-derived fuel) units: 200 parts per million by dry volume measured at 7.0% oxygen, 24-hour block average, geometric mean.

3. For mass burn rotary refractory units: 100 parts per million by dry volume measured at 7.0% oxygen, four-hour block average, arithmetic mean.

4. For mass burn rotary waterwall units: 250 parts per million by dry volume measured at 7.0% oxygen, 24-hour block average, arithmetic mean.

5. For mass burn waterwall and refractory units: 100 parts per million by dry volume measured at 7.0% oxygen, four-hour block average, arithmetic mean.

6. For mixed fuel-fired (pulverized coal/refuse-derived fuel) units: 150 parts per million by dry volume measured at 7.0% oxygen, four-hour block average, arithmetic mean.

7. For modular starved-air and excess air units: 50 parts per million by dry volume measured at 7.0% oxygen, four-hour block average, arithmetic mean.

8. For spreader stoker, mixed fuel-fired (coal/refuse-derived fuel) units: 200 parts per million by dry volume measured at 7.0% oxygen, 24-hour daily block average, arithmetic mean.

9. For stoker, refuse-derived fuel units: 200 parts per million by dry volume measured at 7.0% oxygen, 24-hour daily block average, arithmetic mean.
