Consistent removal is calculated by taking the average of the lowest 50 percent of the removal measured according to part 7049.0410. All sample data obtained for the measured pollutant during the time period prescribed in part 7049.0410 must be reported and used in computing consistent removal.
If a pollutant is measurable in the influent but not in the effluent, the effluent level may be assumed to be the limit of measurement, and those data may be used to calculate consistent removal by the POTW authority at its discretion and subject to approval by the agency. If the pollutant is not measurable in the influent, the data may not be used to calculate consistent removal. "Measurable" means the ability of the analytical method or protocol to quantify as well as identify the presence of the pollutant in question.
