Table 1 to Subpart FFFF of Part 63 - Emission Limits and Work Practice Standards for Continuous Process Vents

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 ≥98 percent by weight or to an outlet process concentration ≤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 ≥99 percent by weight, or to ≤0.45 kg/hr, or to ≤20 ppmv; or
ii. Use a halogen reduction device before the combustion device to reduce the halogen atom mass emission rate to ≤0.45 kg/hr or to a concentration ≤20 ppmv.
3. Group 2 continuous process vent at an existing source You use a recovery device to maintain the TRE level >1.9 but ≤5.0 Comply with 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 >5.0 but ≤8.0 Comply with the requirements in § 63.993 and the requirements referenced therein.
