Monthly Average Concentration means the arithmetic average (proportional to flow) of all daily determinations of concentration made during a calendar month. Daily determinations of concentration made using a composite sample shall be the concentration of the composite sample. When grab samples are used, the daily determinations of concentration shall be the arithmetic average (weighted by flow value) of all the samples collected during the calendar day.

More Definitions of Monthly Average Concentration

Monthly Average Concentration means the average discharge concentration during 30- consecutive day period (for reporting purposes a calendar month). It shall be determined by the summation of all daily concentrations for 30 days (calendar month) divided by the total number of days on which the values were obtained. If more than one sample is taken on a calendar day, the average of all such samples shall be the daily concentration of the day.
