40 CFR Appendix Table 3 to Subpart FFFF of Part 63 - Emission Limits for Hydrogen Halide and Halogen HAP Emissions or HAP Metals Emissions From Process Vents
As required in § 63.2465, you must meet each emission limit in the following table that applies to your process vents that contain hydrogen halide and halogen HAP emissions or PM HAP emissions:
|For each . . .||You must . . .|
|1. Process with uncontrolled hydrogen halide and halogen HAP emissions from process vents ≥1,000 lb/yr||a. Reduce collective hydrogen halide and halogen HAP emissions by ≥99 percent by weight or to an outlet concentration ≤20 ppmv by venting through one or more closed-vent systems to any combination of control devices, or|
|b. Reduce the halogen atom mass emission rate from the sum of all batch process vents and each individual continuous process vent to ≤0.45 kg/hr by venting through one or more closed-vent systems to a halogen reduction device.|
|2. Process at a new source with uncontrolled emissions from process vents ≥150 lb/yr of HAP metals||Reduce overall emissions of HAP metals by ≥97 percent by weight.|
