Open Table
| 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. |
