| For— | For the following operating limit— | You must demonstrate continuous compliance by— |
|---|---|---|
| 1. Each non-flare combustion device.b | a. Maintain the 3-hourc average combustion zone temperature at or above the operating limit establishing during the performance test | i. Passing the emissions through the control device; and ii. Collecting the combustion zone temperature data according to §63.8688(b); and iii. Reducing combustion zone temperature data to 3-hourc averages according to calculations in Table 3 to this subpart; and iv. Maintaining the 3-hourc average combustion zone temperature within the level established during the performance test. |
| 2. Each flare | Meet the operating requirements specified in §63.11(b) | The flare pilot light must be present at all times and the flare must be operating at all times that emissions may be vented to it. |
| 3. Control devices used to comply with the particulate matter emission standards | a. Maintain the 3-hourc average inlet gas temperature at or below the operating limit established during the performance test; and | i. Passing the emissions through the control device; and ii. Collecting the inlet gas temperature and pressure dropd data according to §63.8688(b) and (c); and |
| b. Maintain the 3-hourc average pressure drop across deviced within the operating range limits that were established pursuant to §63.8689(b) and/or (d) | iii. Reducing inlet gas temperature and pressure dropd data to 3-hourc averages according to calculations in Table 3 to this subpart; and iv. Maintaining the 3-hourc average inlet gas temperature within the level established during the performance test; and |
|
| v. Maintaining the 3-hourc average pressure drop across deviced within the level established pursuant to §63.8689(b) and/or (d). | ||
| 4. Other control devices that are neither a combustion device nor a control device used to comply with the particulate matter emission standards | a. Maintain the monitoring parameters within the operating limits established during the performance test | i. Passing the emissions through the devices; ii. Collecting the monitoring parameter data according to §63.8688(d); and iii. Reducing the monitoring parameter data to 3-hourc averages according to calculations in Table 3 to this subpart; and iv. Maintaining the monitoring parameters within the level established during the performance test. |
aThe operating limits specified in Table 2 to this subpart and the requirements specified in Table 5 to this subpart are applicable if you are monitoring control device operating parameters to demonstrate continuous compliance. If you use a CEMS or COMS to demonstrate compliance with the emission limits, you are not required to record control device operating parameters. However, you must maintain emissions below the value established during the initial performance test. Data from the CEMS and COMS must be reduced as specified in §§63.8690 and 63.8(g)(1) through (4).
bContinuous parameter monitoring is not required if (1) the emissions are routed to a boiler or process heater with a with a design heat input capacity of 44 MW or greater; or (2) the emissions are introduced into the flame zone of a boiler or process heater.
cA 15-minute averaging period can be used as an alternative to the 3-hour averaging period for this parameter.
dAs 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.
