Section 9VAC5-40-7980 - Standard for carbon monoxide

No owner or other person shall cause or permit to be discharged into the atmosphere from any affected facility any gases that contain carbon monoxide in excess of the following limits:

1. For mass burn waterwall units: 100 parts per million by volume, corrected to 7.0% oxygen, dry basis, calculated as an arithmetic average (four-hour average).
2. For mass burn refractory units: 100 parts per million by volume, corrected to 7.0% oxygen, dry basis, calculated as an arithmetic average (four-hour average).
3. For mass burn rotary refractory units: 100 parts per million by volume, corrected to 7.0% oxygen, dry basis, calculated as an arithmetic average (24-hour average).
4. For mass burn rotary waterwall units: 250 parts per million by volume, corrected to 7.0% oxygen, dry basis, calculated as an arithmetic average (24-hour average).
5. For modular starved air units: 50 parts per million by volume, corrected to 7.0% oxygen, dry basis, calculated as an arithmetic average (four-hour average).
6. For modular excess air units: 50 parts per million by volume, corrected to 7.0% oxygen, dry basis, calculated as an arithmetic average (four-hour average).
7. For refuse-derived fuel stokers: 200 parts per million by volume, corrected to 7.0% oxygen, dry basis, calculated as an arithmetic average (24-hour average).
8. For bubbling fluidized bed combustors: 100 parts per million by volume, corrected to 7.0% oxygen, dry basis, calculated as an arithmetic average (four-hour average).
9. For circulating fluidized bed combustors: 100 parts per million by volume, corrected to 7.0% oxygen, dry basis, calculated as an arithmetic average (four-hour average).
10. For pulverized coal/refuse-derived fuel mixed fuel-fired combustors: 150 parts per million by volume, corrected to 7.0% oxygen, dry basis, calculated as an arithmetic average (four-hour average).
11. For spreader stoker coal/refuse-derived fuel mixed fuel-fired combustors: 200 parts per million by volume, corrected to 7.0% oxygen, dry basis, calculated as an arithmetic average (24-hour average).
