Monthly Average definition

Monthly Average means the highest allowable average of “daily discharges” over a calendar month, calculated as the sum of all “daily discharges” measured during a calendar month divided by the number of “daily discharges” measured during that month. For Fecal Coliform Bacteria (FCB) or E-Coli, report the monthly average.

Monthly Average means the total mass or flow-weighted concentration of all daily discharges during a calendar month on which daily discharges are sampled or measured, divided by the number of daily discharges sampled and/or measured during such calendar month.

Monthly Average means the sum of all “daily discharges” measured during a calendar month divided by the number of “daily discharges” measured during that month.

Examples of Monthly Average in a sentence

• For publicly owned treatment works, the 30-day average (or Monthly Average) percent removal for Biochemical Oxygen Demand and Total Suspended Solids shall not be less than 85 percent unless otherwise authorized by the permitting authority in accordance with 40 CFR 133.103.

• For E-Coli, report the Daily Maximum as the highest “daily discharge” during the calendar month, and the Monthly Average as the geometric mean of all “daily discharges” within a calendar month, in colonies per 100 ml.

• The WLAs are then applied as effluent limits, per Section 5.4.2 of the TSD, where the CMC is the Daily Maximum and the CCC is the Monthly Average.

• Monthly Average Discharge Limitation means the highest allowable average of "daily discharges" over a calendar month, calculated as the sum of all "daily discharges" measured during a calendar month divided by the number of "daily discharges" measured during that month.

• For FCB, report the Daily Maximum as the highest “daily discharge” during the calendar month, and the Monthly Average as the geometric mean of all “daily discharges” within a calendar month, in colonies per 100 ml.

More Definitions of Monthly Average

Monthly Average means the quotient obtained by dividing (i) the amount of fees paid or payable by the Fund for the twelve (12) calendar months immediately prior to the last Loss Date (as defined below), by (ii) 12.

Monthly Average means the average of "daily discharges" over a calendar month, calculated as the sum of all "daily discharges" measured during a calendar month divided by the number of "daily discharges" measured during the month. The monthly average for E coli bacteria is the geometric mean of "daily discharges" measured during the calendar month. In computing the geometric mean for E coli bacteria, the value one (1) shall be substituted for sample results of zero. [11 Miss. Admin. Code Pt. 6, R. 1.1.1.A(44).]

Monthly Average means the sum of the concentrations (or mass loadings, expressed in terms of pounds per day, or such other unit of measurement) of a pollutant divided by the number of samples taken during a calendar month. The concentrations (or loadings) that are added are single numbers for single calendar days for all days during the calendar month for which analyses are obtained (whether by the user or the POTW), but the concentrations (or loadings) may be based upon a sample or samples taken over either all or part of that day and upon single or multiple analyses for that day, as determined by the POTW Manager. If no samples are taken during particular months because less than monthly sampling is required for a pollutant parameter (e.g., a specified quarterly monitoring period), the monthly average for each month within the specified monitoring period shall be deemed to be the sum of concentrations (or loadings) for the monitoring period divided by number of samples taken during the monitoring period.

Monthly Average means the arithmetic mean of all measurements taken during the month.

Monthly Average limitation means the highest allowable discharge of “daily discharges” over a calendar month, calculated as the sum of all “daily discharges” measured during a calendar month divided by the number of “daily discharges” measure during that month.

Monthly Average means the highest allowable average of “daily discharges” over a calendar month, calculated as the sum of all “daily discharges” measured during a calendar month divided by the number of “daily discharges” measured during that month. For E. coli or FCB, report the Monthly Average as the geometric mean of all “daily discharges” within a calendar month (see Part IV.14 and IV.15 above, respectively).

Monthly Average means the highest allowable average of “daily discharges” over a calendar month, calculated as the sum of all “daily discharges” measured during a calendar month divided by the number of “daily discharges” measured during that month. For Fecal Coliform Bacteria (FCB) or E-Coli, calculate the monthly average as a geometric mean of all effluent samples collected during a calendar month in colonies per 100 mL.
