Demonstrating Continuous Compliance
June 9, 2020
As stated in §63.7540, you must show continuous compliance with the emission limitations for each boiler or process heater according to the following:
Open Table
| If you must meet the following operating limits or work practice standards . . . | You must demonstrate continuous compliance by . . . |
|---|---|
| 1. Opacity | a. Collecting the opacity monitoring system data according to §63.7525(c) and §63.7535; and |
| b. Reducing the opacity monitoring data to 6-minute averages; and | |
| c. Maintaining daily block average opacity to less than or equal to 10 percent or the highest hourly average opacity reading measured during the performance test run demonstrating compliance with the PM (or TSM) emission limitation. | |
| 2. PM CPMS | a. Collecting the PM CPMS output data according to §63.7525; |
| b. Reducing the data to 30-day rolling averages; and | |
| c. Maintaining the 30-day rolling average PM CPMS output data to less than the operating limit established during the performance test according to §63.7530(b)(4). | |
| 3. Fabric Filter Bag Leak Detection Operation | Installing and operating a bag leak detection system according to §63.7525 and operating the fabric filter such that the requirements in §63.7540(a)(7) are met. |
| 4. Wet Scrubber Pressure Drop and Liquid Flow-rate | a. Collecting the pressure drop and liquid flow rate monitoring system data according to §§63.7525 and 63.7535; and |
| b. Reducing the data to 30-day rolling averages; and | |
| c. Maintaining the 30-day rolling average pressure drop and liquid flow-rate at or above the operating limits established during the performance test according to §63.7530(b). | |
| 5. Wet Scrubber pH | a. Collecting the pH monitoring system data according to §§63.7525 and 63.7535; and |
| b. Reducing the data to 30-day rolling averages; and | |
| c. Maintaining the 30-day rolling average pH at or above the operating limit established during the performance test according to §63.7530(b). | |
| 6. Dry Scrubber Sorbent or Carbon Injection Rate | a. Collecting the sorbent or carbon injection rate monitoring system data for the dry scrubber according to §§63.7525 and 63.7535; and |
| b. Reducing the data to 30-day rolling averages; and | |
| c. Maintaining the 30-day rolling average sorbent or carbon injection rate at or above the minimum sorbent or carbon injection rate as defined in §63.7575. | |
| 7. Electrostatic Precipitator Total Secondary Electric Power Input | a. Collecting the total secondary electric power input monitoring system data for the electrostatic precipitator according to §§63.7525 and 63.7535; and |
| b. Reducing the data to 30-day rolling averages; and | |
| c. Maintaining the 30-day rolling average total secondary electric power input at or above the operating limits established during the performance test according to §63.7530(b). | |
| 8. Emission limits using fuel analysis | a. Conduct monthly fuel analysis for HCl or mercury or TSM according to Table 6 to this subpart; and |
| b. Reduce the data to 12-month rolling averages; and | |
| c. Maintain the 12-month rolling average at or below the applicable emission limit for HCl or mercury or TSM in Tables 1 and 2 or 11 through 13 to this subpart. | |
| d. Calculate the HCI, mercury, and/or TSM emission rate from the boiler or process heater in units of lb/MMBtu using Equation 15 and Equations 17, 18, and/or 19 in §63.7530. | |
| 9. Oxygen content | a. Continuously monitor the oxygen content using an oxygen analyzer system according to §63.7525(a). This requirement does not apply to units that install an oxygen trim system since these units will set the trim system to the level specified in §63.7525(a)(7). |
| b. Reducing the data to 30-day rolling averages; and | |
| c. Maintain the 30-day rolling average oxygen content at or above the lowest hourly average oxygen level measured during the CO performance test. | |
| 10. Boiler or process heater operating load | a. Collecting operating load data or steam generation data every 15 minutes. b. Reducing the data to 30-day rolling averages; and |
| c. Maintaining the 30-day rolling average operating load such that it does not exceed 110 percent of the highest hourly average operating load recorded during the performance test according to §63.7520(c). | |
| 11. SO2 emissions using SO2 CEMS | a. Collecting the SO2 CEMS output data according to §63.7525; |
| b. Reducing the data to 30-day rolling averages; and | |
| c. Maintaining the 30-day rolling average SO2 CEMS emission rate to a level at or below the highest hourly SO2 rate measured during the HCl performance test according to §63.7530. |
