40 CFR Part 63, Table 4
| For the operating parameter applicable to you, as specified in Table 3 . . . | You must establish the following operating limit . . . | And you must monitor, record, and demonstrate continuous compliance using these minimum frequencies . . . |
|---|---|---|
| Data measurement | Datarecording | Data averaging period for compliance |
Absorbers (Wet Scrubbers)
| Influent liquid flow | Minimum inlet liquid flow | Continuous | Every 15 minutes | Daily. |
|---|---|---|---|---|
| Influent liquid flow rate and gas stream flow rate | Minimum influent liquid-to-gas ratio a | Continuous | Every 15 minutes | Daily. |
| Pressure drop | Pressure drop range | Continuous | Every 15 minutes | Daily. |
Sorbent Injection
| Sorbent injection rate | Minimum injection rate | Continuous | Every 15 minutes | Daily. |
|---|---|---|---|---|
| Sorbent injection carrier gas flow rate | Minimum carrier gas flow rate | Continuous | Every 15 minutes | Daily. |
Fabric Filters
Alarm time | Maximum alarm time is not established on a site-specific basis but is specified in § 63.605(f)(9) | Continuous | Each date and time of alarm start and stop | Maximum alarm time specified in § 63.605(f)(9).
Wet Electrostatic Precipitator
Secondary voltage | Secondary voltage range | Continuous | Every 15 minutes | Daily.
a If you select the regression model option to monitor influent liquid-to-gas ratio as described in Table 3 to this subpart, then you must also continuously monitor (i.e., record every 15 minutes, and use a daily averaging period) blower amperage, blower static pressure (i.e., fan suction pressure), and any other parameters used in the regression model that are not constants.
