Part II Page 11 of 14 3. EMC: Used herein means the North Carolina Environmental Management Commission. 4. Act or "the Ace The Federal Water Pollution Control Act, also known as the Clean Water Act, as amended, 33 USC 1251, et. seq. Masa/Dy Measuremnts a. The "monthly average discharge: is defined as the total mass of all daily discharges sampled and/or measured during a calendar month on which daily discharges are sample and measured, divided by the number of daily discharges samples and/or measured during such month. It is therefore, an arithmetic mean found by adding the weights of the pollutant found each day of the month and then dividing this sum by the number of days the tests were reported. The limitation is identified as "Daily Average" or "Monthly Average" in Part I of the permit, b. The "weekly average discharge" is defined as the total mass of all daily discharges sampled and/or measured during the calendar week (Sunday -Saturday) on which daily discharges are sampled and measured, divided by the number of daily discharges samples and/or measured during: such week. It is, therefore, an arithmetic mean found by adding the weights of pollutants found each day of the week and then dividing this sum by the number of days the tests were reported. This limitation is identified as "Weekly Average" in Part I of the permit. c. The "maximum daily discharge" is the total mass (weight) of a pollutant discharged during a calendar day. If only one sample is taken during any calendar day the weight of pollutant calculated from it is the "maximum daily discharge." This limitation is identified as "Daily Maximum," in Part I of the permit. d. The "average annual discharge" is defined as the total mass of all daily discharges sample and/or measured during the calendar year on which daily discharges are sampled and measured, divided by the number of daily discharges sampled and/or measured during such year. It is, therefore, an arithmetic mean found by adding the weights of pollutants found each day of the year and then dividing this sum by the number of days the tests were reported. This limitation is defined as "Annual Average" in Part 1 of the permit. Part II Page 12 of 14 6. Doncentrtxon Measurement a. The "average monthly concentration," other than for fecal coliform bacteria, is the sum of the concentrations of all daily discharges samples and/or measured during a calendar month on which daily discharges are sampled and measured, divided by the number of daily discharges sampled and/or measured during such month (arithmetic mean of the daily concentration values). The daily concentration value is equal to the concentration of a composite sample or in the case of grab samples is the arithmetic mean (weighted by flow value) of all the samples collected during that calendar day. The average monthly count for fecal coliform bacteria is the geometric mean of the counts for samples collected during a calendar month. This limitation is identified as "Monthly Average" or "Daily Average" under "Other Limits"" in Part I of the permit. b„ The "average weekly concentration," other than for fecal coliform bacteria, is the sum of the concentrations of all daily discharges sampled and/or measured during a calendar week (Sunday/Saturday) on which daily discharges are sampled and measured divided by the number of daily discharges sampled and/or measured during such week (arithmetic mean of the daily concentration values). The daily concentration value is equal to the concentration of a composite sample or in the case of grab samples is the arithmetic mean (weighted by flow value) of all the samples collected during that calendar day. The average weekly count for fecal coliform bacteria is the geometric mean of the counts for samples collected during a calendar week. This limitation is identified as "Weekly Average" under "Other Limits" in Part I of the permit. c. The "maximum daily concentration" is the concentration of a pollutant discharge during a calendar day. It is identified as "Daily Maximum" under "Other Limits" in Part I of the permit. d. The "average annual concentration," other than for fecal coliform bacteria, is the sum of the concentrations of all daily discharges sampled and/or measured during a calendar year on which daily discharges are sampled and. measured divided by the number of daily discharges sampled and/or measured during such year (arithmetic mean of the daily concentration values). The daily concentration value is equal to the concentration of a composite sample or in the case of grab samples is the arithmetic mean (weighted by flow value) of all the samples collected during that calendar day. The average yearly count for fecal coliform, bacteria is the geometric mean of the counts for samples collected during a calendar year. This limitation is identified as "Annual Average" under "Other Limits" in Part I of the permit. Part II Page 13 of 14 7. Other Measurements a. Flow, (MOD): The flow limit expressed in this permit is the 24 hours average flow, averaged monthly. It is determined as the arithmetic mean of the total daily flows recorded during the calendar month. b. An "instantaneous flow measurement" is a measure of flow taken at the time of sampling, when both the sample and flow will be representative of the total discharge. 8. Types of S a. Composite Sample: These samples consist of grab samples collected at equal intervals and combined proportional to flow, a sample continuously collected proportionally to flow, or equal volumes taken at varying time intervals. If a composite sample is obtained from grab samples, the following requirements apply. The intervals between influent grab samples shall be no greater than hourly. Intervals between effluent grab samples shall be no greater than hourly except where the detention time of the wastewater in the facility is greater than 24 hours, in which case, the interval between grab samples shall be no greater in number of hours than the detention time in number of days; provided, however, in no case may the time between effluent grab samples be greater than six hours nor the number of grab samples less than four during any discharge period of 24 hours or less. b. Grab Sample: Grab samples are individual samples collected over a period of time not exceeding 15 minutes; the grab sample can be taken manually. 9. Calculation of Means a. Arithmetic Mean: The arithmetic mean of any set of values is the summation of the individual values divided by the number of individual values. b. Geometric Mean: The geometric mean of any set of values is the Nth root of the product of the individual values where N is equal to the number of individual values. The geometric mean is equivalent to the antilog of the arithmetic mean of the logarithms of the individual values. For purposes of calculating the geometric mean, values of zero (0) shall be considered to be one (1). c. Weighted by Flow Value: Weighted by flow value means the summation of each concentration times its respective flow divided by the summation of the respective flows. Part II Page 14 of 14 10. CalendarD A calendar day is defined as the period from midnight of one day until midnight of the next day. However, for purposes of this permit, any consecutive 24-hour period that reasonably represents the calendar day may be used for sampling. 11.
