Table 1 to Subpart HHHHH of Part 63—Emission Limits and Work Practice Standards for Process Vessels
As required in § 63.8005, you must meet each emission limit and work practice standard in the following table that applies to your process vessels.
For each . . . You must . . . And you must . . .
1. Portable process vessel at an existing source a. Equip the vessel with a cover or lid that must be in place at all times when the vessel contains a HAP, except for material additions and sampling Nonapplicable.
2. Stationary process vessel at an existing source a. Equip the vessel with a cover or lid that must be in place at all times when the vessel contains a HAP, except for material additions and sampling; or i. Considering both capture and any combination of control (except a flare), reduce emissions of organic HAP with a vapor existing pressure ≥0.6 kPa by ≥75 percent by weight, and reduce emissions of organic HAP with a vapor pressure <0.6 kPa by ≥60 percent by weight.
b. Equip the vessel with a tightly fitting vented cover or lid that must be closed at all times when the vessel contains HAP, except for material additions and sampling i. Reduce emissions of organic HAP with a vapor pressure ≥0.6 kPa by ≥75 percent by weight, and reduce emissions of organic HAP with a vapor pressure <0.6 kPa by ≥60 percent by weight, by venting emissions through a closed-vent system to any combination of control devices (except a flare); orii. Reduce emissions of total organic HAP by venting emissions from a non-halogenated vent stream through a closed-vent system to a flare; or iii. Reduce emissions of total organic HAP by venting emissions through a closed-vent system to a condenser that reduces the outlet gas temperature to:
<10 °C if the process vessel contains HAP with a partial pressure <0.6 kPa, or
<2 °C if the process vessel contains HAP with a partial pressure ≥0.6 kPa and <17.2 kPa, or
<−5 °C if the process vessel contains HAP with a partial pressure ≥17.2 kPa.
3. Portable and stationary process vessel at a new source a. Equip the vessel with a tightly fitting vented cover or lid that must be closed at all times when the vessel contains HAP, except for material additions and sampling i. Reduce emissions of total organic HAP by ≥95 percent by weight by venting emissions through a closed-vent system to any combination of control devices (except a flare); orii. Reduce emissions of total organic HAP by venting emissions from a non-halogenated vent stream through a closed-vent system to a flare; or iii. Reduce emissions of total organic HAP by venting emissions through a closed-vent system to a condenser that reduces the outlet gas temperature to: <−4 °C if the process vessel contains HAP with a partial pressure <0.7 kPa, or
<−20 °C if the process vessel contains HAP with a partial pressure ≥0.7 kPa and <17.2 kPa, or
<−30 °C if the process vessel contains HAP with a partial pressure ≥17.2 kPa.
4. Halogenated vent steam from a process vessel subject to the requirements of item 2 or 3 of this table for which you use a combustion control 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 ≥95 percent; orii. Reduce overall emissions of hydrogen halide and halogen HAP to ≤0.45 kilogram per hour (kg/hr).
b. Use a halogen reduction device before the combustion control device Reduce the halogen atom mass emission rate to ≤0.45 kg/hr.
