Open Table
| Final recovery device | Parameters to be monitoreda | Recordkeeping and reporting requirements for monitored parameters |
|---|---|---|
| Absorberb | Exit temperature of the absorbing liquid [63.114(b)(1)], and | 1. Continuous recordsc. 2. Record and report the exit temperature of the absorbing liquid averaged over the full period of the TRE determination—NCS.d |
| 3. Record the daily average exit temperature of the absorbing liquid for each operating daye. | ||
| 4. Report all the daily average exit temperatures of the absorbing liquid that are outside the range established in the NCS or operating permit—PRf. | ||
| Exit specific gravity [63.114(b)(1)] | 1. Continuous records. 2. Record and report the exit specific gravity averaged over the full period of the TRE determination—NCS. |
|
| 3. Record the daily average exit specific gravity for each operating daye. | ||
| 4. Report all daily average exit specific gravity values that are outside the range established in the NCS or operating permit—PR. | ||
| Condenserd | Exit (product side) temperature [63.114(b)(2)] | 1. Continuous records. 2. Record and report the exit temperature averaged over the full period of the TRE determination—NCS. |
| 3. Record the daily average exit temperature for each operating daye. | ||
| 4. Report all daily average exit temperatures that are outside the range established in the NCS or operating permit—PR. | ||
| Carbon adsorberd | Total regeneration stream mass or volumetric flow during carbon bed regeneration cycle(s) [63.114(b)(3)], and | 1. Record of total regeneration stream mass or volumetric flow for each carbon bed regeneration cycle. 2. Record and report the total regeneration stream mass or volumetric flow during each carbon bed regeneration cycle during the period of the TRE determination—NCS. |
| 3. Report all carbon bed regeneration cycles when the total regeneration stream mass or volumetric flow is outside the range established in the NCS or operating permit—PR. | ||
| Temperature of the carbon bed after regeneration [and within 15 minutes of completing any cooling cycle(s)] [63.114(b)(3)] | 1. Records of the temperature of the carbon bed after each regeneration. 2. Record and report the temperature of the carbon bed after each regeneration during the period of the TRE determination—NCS. |
|
| 3. Report all carbon bed regeneration cycles during which temperature of the carbon bed after regeneration is outside the range established in the NCS or operating permit—PR. | ||
| All recovery devices (as an alternative to the above) | Concentration level or reading indicated by an organic monitoring device at the outlet of the recovery device [63.114 (b)] | 1. Continuous records. 2. Record and report the concentration level or reading averaged over the full period of the TRE determination—NCS. |
| 3. Record the daily average concentration level or reading for each operating daye. | ||
| 4. Report all daily average concentration levels or readings that are outside the range established in the NCS or operating permit—PR. |
aRegulatory citations are listed in brackets.
bAlternatively, these devices may comply with the organic monitoring device provisions listed at the end of this table under “All Recovery Devices.”
c“Continuous records” is defined in §63.111 of this subpart.
dNCS = Notification of Compliance Status described in §63.152 of this subpart.
eThe daily average is the average of all values recorded during the operating day. If all recorded values during an operating day are within the range established in the NCS or operating permit, a statement to this effect can be recorded instead of the daily average.
fPR= Periodic Reports described in §63.152 of this subpart.
