| For— | You musta |
|---|---|
| 1. Non-flare combustion devices with a design heat input capacity less than 44 MW or where the emissions are not introduced into the flame zone | Maintain the 3-hour averageb combustion zone temperature at or above the operating limit established during the performance test. |
| 2. Flares | Meet the operating requirements specified in §63.11(b). |
| 3. Control devices used to comply with the particulate matter standards. | a. Maintain the 3-hour averageb inlet gas temperature at or below the operating limit established during the performance test; and |
| b. Maintain the 3-hour averageb pressure drop across the devicec within the operating range limits (i.e., at or above a minimum pressure drop and at or below a maximum pressure drop) established during the performance test, or as an alternative, established according to the manufacturer's specifications as specified in §63.8689(d). | |
| 4. Other control devices that are neither a combustion device nor a control device used to comply with the particulate matter emission standards | Maintain the approved monitoring parameters within the operating limits established during the performance test. |
aThe operating limits specified in Table 2 to this subpart are applicable if you are monitoring control device operating parameters to demonstrate continuous compliance. If you are using a CEMS or COMS, you must maintain emissions below the value established during the initial performance test.
bA 15-minute averaging period can be used as an alternative to the 3-hour averaging period for this parameter.
cAs an alternative to monitoring the pressure drop across the control device, owners or operators using an ESP to achieve compliance with the emission limits specified in Table 1 to this subpart can monitor the voltage to the ESP. If this option is selected, the ESP voltage must be maintained at or above the operating limit established during the performance test.
