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 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 c. As specified in § 63.8005(i) , on or before February 22, 2024, during the addition of dry material, route material containing metal HAP to a capture and control system that is maintained and operated according to the provisions of § 63.8005 | i. Considering both capture and any combination of control (except a flare), reduce emissions of organic HAP with a vapor existing pressure [GREATER THAN EQUAL TO]0.6 kPa by [GREATER THAN EQUAL TO]75 percent by weight, and reduce emissions of organic HAP with a vapor pressure [LESS THAN]0.6 kPa by [GREATER THAN EQUAL TO]60 percent by weight. i. Reduce emissions of organic HAP with a vapor pressure [GREATER THAN EQUAL TO]0.6 kPa by [GREATER THAN EQUAL TO]75 percent by weight, and reduce emissions of organic HAP with a vapor pressure [LESS THAN]0.6 kPa by [GREATER THAN EQUAL TO]60 percent by weight, by venting emissions through a closed-vent system to any combination of control devices (except a flare); or |
ii. 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: | ||
[LESS THAN]10 °C if the process vessel contains HAP with a partial pressure [LESS THAN]0.6 kPa, or | ||
[LESS THAN]2 °C if the process vessel contains HAP with a partial pressure [GREATER THAN EQUAL TO]0.6 kPa and [LESS THAN]17.2 kPa, or | ||
[LESS THAN]-5 °C if the process vessel contains HAP with a partial pressure [GREATER THAN EQUAL TO]17.2 kPa. | ||
i. Reduce emissions of material containing metal HAP to 0.014 gr/dscf or less. | ||
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 b. As specified in § 63.8005(i) , upon startup or February 22, 2023, whichever is later, during the addition of dry material, route material containing metal HAP to a capture and control system that is maintained and operated according to the provisions of § 63.8005 | i. Reduce emissions of total organic HAP by [GREATER THAN EQUAL TO]95 percent by weight by venting emissions through a closed-vent system to any combination of control devices (except a flare); or ii. 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: |
[LESS THAN]-4 °C if the process vessel contains HAP with a partial pressure [LESS THAN]0.7 kPa, or | ||
[LESS THAN]-20 °C if the process vessel contains HAP with a partial pressure [GREATER THAN EQUAL TO]0.7 kPa and [LESS THAN]17.2 kPa, or | ||
[LESS THAN]-30 °C if the process vessel contains HAP with a partial pressure [GREATER THAN EQUAL TO]17.2 kPa. | ||
i. Reduce emissions of material containing metal HAP to 0.0079 gr/dscf or less. | ||
4. Halogenated vent stream 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 b. Use a halogen reduction device before the combustion control device | i. Reduce overall emissions of hydrogen halide and halogen HAP by [GREATER THAN EQUAL TO]95 percent; or ii. Reduce overall emissions of hydrogen halide and halogen HAP to [LESS THAN EQUAL TO]0.45 kilogram per hour (kg/hr). Reduce the halogen atom mass emission rate to [LESS THAN EQUAL TO]0.45 kg/hr. |
