Table 3. Operating Limits for Incinerators and Wet Scrubbers
For these operating parameters	You must establish operating limits	And monitoring using these minimum frequencies
For these operating parameters	You must establish operating limits	Data Measurement	Data Recording	Averaging Time
1. Charge rate	Maximum charge rate	Continuous	Every hour	Daily for batch units. 3-hour rolling for continuous and intermittent units^a
2. Pressure drop across the wet scrubber or amperage to wet scrubber	Minimum pressure drop or amperage	Continuous	Every 15 minutes	3-hour rolling^a
3. Scrubber liquor flow rate	Minimum flow rate	Continuous	Every 15 minutes	3-hour rolling^a
4. Scrubber liquor pH	Minimum pH		Every 15 minutes	3-hour rolling^a

^aCalculated each hour as the average of the previous 3 operating hours.
