40 CFR Table 4
Model Rule—Operating Parameters for Existing Sewage Sludge Incineration Units
June 9, 2020
Open Table
| For these operating parameters | You must establish these operating limits | And monitor using these minimum frequencies | ||
|---|---|---|---|---|
| Data measurement | Data recordingb | Data averaging period for compliance |
||
| All sewage sludge incineration units | ||||
| Combustion chamber operating temperature (not required if afterburner temperature is monitored) | Minimum combustion chamber operating temperature or afterburner temperature | Continuous | Every 15 minutes | 12-hour block. |
| Fugitive emissions from ash handling | Site-specific operating requirements | Not applicable | No applicable | Not applicable. |
| Scrubber | ||||
| Pressure drop across each wet scrubber | Minimum pressure drop | Continuous | Every 15 minutes | 12-hour block. |
| Scrubber liquid flow rate | Minimum flow rate | Continuous | Every 15 minutes | 12-hour block. |
| Scrubber liquid pH | Minimum pH | Continuous | Every 15 minutes | 3-hour block. |
| Fabric Filter | ||||
| Alarm time of the bag leak detection system alarm | Maximum alarm time of the bag leak detection system alarm (this operating limit is provided in §60.4850 and is not established on a site-specific basis) | |||
| Electrostatic precipitator | ||||
| Secondary voltage of the electrostatic precipitator collection plates | Minimum power input to the electrostatic precipitator collection plates | Continuous | Hourly | 12-hour block. |
| Secondary amperage of the electrostatic precipitator collection plates | ||||
| Effluent water flow rate at the outlet of the electrostatic precipitator | Minimum effluent water flow rate at the outlet of the electrostatic precipitator | Hourly | Hourly | 12-hour block. |
| Activated carbon injection | ||||
| Mercury sorbent injection rate | Minimum mercury sorbent injection rate | Hourly | Hourly | 12-hour block. |
| Dioxin/furan sorbent injection rate | Minimum dioxin/furan sorbent injection rate | |||
| Carrier gas flow rate or carrier gas pressure drop | Minimum carrier gas flow rate or minimum carrier gas pressure drop | Continuous | Every 15 minutes | 12-hour block. |
| Afterburner | ||||
| Temperature of the afterburner combustion chamber | Minimum temperature of the afterburner combustion chamber | Continuous | Every 15 minutes | 12-hour block. |
aAs specified in §60.5190, you may use a continuous emissions monitoring system or continuous automated sampling system in lieu of establishing certain operating limits.
bThis recording time refers to the minimum frequency that the continuous monitor or other measuring device initially records data. For all data recorded every 15 minutes, you must calculate hourly arithmetic averages. For all parameters, you use hourly averages to calculate the 12-hour or 3-hour block average specified in this table for demonstrating compliance. You maintain records of 1-hour averages.
