6. What Are the Continuous Compliance Requirements?

coal and stackTo demonstrate continuous compliance with the emission limitations, a source must monitor and comply with the applicable site-specific operating limits established during the performance tests or fuel analysis. Upon detecting an excursion or exceedance, the source must restore operation of the unit to its normal or usual manner of operation as soon as practical in accordance with good air pollution control practices for minimizing emissions. The response shall include minimizing the period of any startup, shutdown or malfunction and taking any necessary corrective actions to restore normal operation and prevent the likely recurrence of the cause of an excursion or exceedance. Such actions may include initial inspections and evaluation, recording that operations returned to normal without operator action, or any necessary follow-up actions to return operation to below the work practice standard.

coal and backhoeFor boilers and process heaters that choose to comply with any emission limit based on fuel analysis, you must maintain monthly fuel records to demonstrate that the content of fuel is maintained below the appropriate applicable emission limit. If the source chooses to comply using emissions averaging, they must demonstrate on a monthly basis that mercury, metals, PM, and HCl emission limits can be met over a 12-month period.
