40 C.F.R. § 63.1662-63 app Table 1 to Subpart FFFF of Part 63
Current through May 31, 2024
As required in § 63.2455 , you must meet each emission limit and work practice standard in the following table that applies to your continuous process vents:
| For each . . . | For which . . . | Then you must . . . |
| 1. Group 1 continuous process vent | a. Not applicable | i. Reduce emissions of total organic HAP by [GREATER THAN EQUAL TO]98 percent by weight or to an outlet process concentration [LESS THAN EQUAL TO]20 ppmv as organic HAP or TOC by venting emissions through a closed-vent system to any combination of control devices (except a flare); or |
| ii. Reduce emissions of total organic HAP by venting emissions through a closed vent system to a flare; or | ||
| iii. Use a recovery device to maintain the TRE above 1.9 for an existing source or above 5.0 for a new source. | ||
| 2. Halogenated Group 1 continuous process vent stream | a. You use a combustion control device to control organic HAP emissions | i. Use a halogen reduction device after the combustion device to reduce emissions of hydrogen halide and halogen HAP by [GREATER THAN EQUAL TO]99 percent by weight, or to [LESS THAN EQUAL TO]0.45 kg/hr, or to [LESS THAN EQUAL TO]20 ppmv; or |
| ii. Use a halogen reduction device before the combustion device to reduce the halogen atom mass emission rate to [LESS THAN EQUAL TO]0.45 kg/hr or to a concentration [LESS THAN EQUAL TO]20 ppmv. | ||
| 3. Group 2 continuous process vent at an existing source | You use a recovery device to maintain the TRE level [GREATER THAN]1.9 but [LESS THAN EQUAL TO]5.0 | Comply with the requirements in § 63.2450(e)(4) and the requirements in § 63.993 and the requirements referenced therein. |
| 4. Group 2 continuous process vent at a new source | You use a recovery device to maintain the TRE level [GREATER THAN]5.0 but [LESS THAN EQUAL TO]8.0 | Comply with the requirements in § 63.2450(e)(4) and the requirements in § 63.993 and the requirements referenced therein. |
| 5. Continuous process vent | Beginning no later than the compliance dates specified in § 63.2445(i) , the continuous process vent contains ethylene oxide such that it is considered to be in ethylene oxide service as defined in § 63.2550 | Comply with the applicable emission limits specified in items 1 through 4 of this Table, and also: i. Reduce emissions of ethylene oxide by venting emissions through a closed-vent system to a flare; or ii. Reduce emissions of ethylene oxide by venting emissions through a closed-vent system to a control device that reduces ethylene oxide by [GREATER THAN EQUAL TO]99.9 percent by weight, or to a concentration [LESS THAN]1 ppmv for each process vent or to [LESS THAN]5 pounds per year for all combined process vents. |
