Table 2 to Subpart FFFF of Part 63—Emission Limits and Work Practice Standards for Batch Process Vents
As required in § 63.2460, you must meet each emission limit and work practice standard in the following table that applies to your batch process vents:
For each . . . Then you must . . . And you must . . .
1. Process with Group 1 batch process vents a. Reduce collective uncontrolled organic HAP emissions from the sum of all batch process vents within the process by ≥98 percent by weight by venting emissions from a sufficient number of the vents through one or more closed-vent systems to any combination of control devices (except a flare); or Not applicable.
b. Reduce collective uncontrolled organic HAP emissions from the sum of all batch process vents within the process by ≥95 percent by weight by venting emissions from a sufficient number of the vents through one or more closed-vent systems to any combination of recovery devices or a biofilter, except you may elect to comply with the requirements of subpart WW of this part for any process tank; or Not applicable.
c. Reduce uncontrolled organic HAP emissions from one or more batch process vents within the process by venting through a closed-vent system to a flare or by venting through one or more closed-vent systems to any combination of control devices (excluding a flare) that reduce organic HAP to an outlet concentration ≤20 ppmv as TOC or total organic HAP. For all other batch process vents within the process, reduce collective organic HAP emissions as specified in item 1.a and/or item 1.b of this table.
2. Halogenated Group 1 batch process vent for which you use a combustion device to control organic HAP emissions a. Use a halogen reduction device after the combustion control device; or i. Reduce overall emissions of hydrogen halide and halogen HAP by ≥99 percent; orii. Reduce overall emissions of hydrogen halide and halogen HAP to ≤0.45 kg/hr; oriii. Reduce overall emissions of hydrogen halide and halogen HAP to a concentration ≤20 ppmv.
b. Use a halogen reduction device before the combustion control device Reduce the halogen atom mass emission rate to ≤0.45 kg/hr or to a concentration ≤20 ppmv.
