- 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. |
