Daily Discharge For pollutants expressed in units of mass: Calculate the total mass of the pollutant discharged over the day. Example: Set of measurements: 2, 9, 8, 5, 6 2 + 9+ 8+5+6 30 Arithmetic Mean = ----------------------- = — = 6 J
For pollutants with limitations expressed in other units of measurement: Calculate the average observed/analytical value of the pollutant over the day..
Daily Average or Monthly Average < The average of daily discharges over a calendar month.L '■
Calculate the sum of all daily discharges measured during a calendar month divided the number of daily discharges measured during that month.
Average Concentration: Seven (7) Day Average Concentration (Quality): Report in the Sample Measurement box under maximum. Calculate the average of all daily discharges for each 7 days inthemonitoftng period. The Sample Measurement is the highest of the 7 day averages calculated dtjringthe monitoring period.
Thirty (30) Day Average Concentration (Quality): Report in the Sample Measurement box under average. ' . Calculate the average of all daily discharges during the 30 day irfOhitoring period. The Sample Measurement is the average of all samples measured during the 1 month (30 day) monitoring period. When the SPDES perrhH requires Only 1 observed/analytical value per monitoring period and only one sample was taken, the 30 day and 7 day Sample Measurements are the same. See Repeated Single Values, page 16.
Average Loading: ------ Itiplying the daily flow in million gallons per day (MGD), first and then by the unit conversion 8.34 Ibs/MG mg/L Loading (ibs/day) GD) (mg/L) x 8.34 Ibs/MG Z mg/L Q =: Daily flow in MGD for each day observed/analytical values are taken. C Parameter concentration in mg/L 8.34 Ibs/MG = unit conversion for weight of one gallon of water in pounds. ' \ mg/L
Seven (7) Day Average Loading (Quantity): Report in the Sample Measurement 'asurement box under maximum. Calculate the average of all observed/analytical values for each 7 days in the monitoring period. The Sample Measurement is the highest of the 7 day averages calculated during the monitoring period.
Thirty (30) Day Average Loading (Quantity): Report in the Sample Measurement box under average. Calculate the average of all observed/analytical values during the 30 day monitoring period.
