- Table 1 to Subpart JJJJ of Part 63—Operating Limits if Using Add-On Control Devices and Capture System
If you are required to comply with operating limits by § 63.3321, you must comply with the applicable operating limits in the following table:
| For the following device: | You must meet the following operating limit: | And you must demonstrate continuous compliance with operating limits by: | 1. Thermal oxidizer | a. The average combustion temperature in any 3-hour period must not fall more than 50 °F below the combustion temperature limit established according to § 63.3360(e)(3)(i) | i. Collecting the combustion temperature data according to § 63.3350(e)(10);
ii. Reducing the data to 3-hour block averages; and | iii. Maintain the 3-hour average combustion temperature at or above the temperature limit. | 2. Catalytic oxidizer | a. The average temperature at the inlet to the catalyst bed in any 3-hour period must not fall more than 50 degrees Fahrenheit below the combustion temperature limit established according to § 63.3360(e)(3)(ii) | i. Collecting the catalyst bed inlet temperature data according to § 63.3350(e)(10);
ii. Reducing the data to 3-hour block averages; and iii. Maintain the 3-hour average catalyst bed inlet temperature at or above the temperature limit. | b. The temperature rise across the catalyst bed must not fall below 80 percent of the limit established according to § 63.3360(e)(3)(ii), provided that the minimum temperature is always 50 degrees Fahrenheit above the catalyst's ignition temperature | i. Collecting the catalyst bed inlet and outlet temperature data according to § 63.3350(e)(10);
ii. Reducing the data to 3-hour block averages; and iii. Maintain the 3-hour average temperature rise across the catalyst bed at or above the limit, and maintain the minimum temperature at least 50 degrees Fahrenheit above the catalyst's ignition temperature | 3. Emission capture system | Submit monitoring plan to the Administrator that identifies operating parameters to be monitored according to § 63.3350(f) | Conduct monitoring according to the plan (§ 63.3350(f)(3)). |
