M s/Day 11e ure ntm 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 ofdaily 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 identified as as "Monthly Average" in Part I of the permit. Th. e '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. The "maimu pollutant d taken durin it is the "i)a lv Maximum, daily discharge." is the total mass (weight) of a charged during e calendar. day. If only one sample is any calendar day the weight of pollutant calculated from ximiim daily discharge." This limitation in Part I of the per-mi_t. identified as Part II Page 12 of 14 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 I of the permit. 6. Concentration Me su 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 aro 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 fox fecal coliform bacteria is the geometric mean of the counts for samples collected during a calendar month. This limitation is identified as "Monthly Average" under "Other Limits" in Part 1 of the permit. b. The aerage 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 thedaily 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. If only one sample is taken during any calendar day the concentration of pollutant calculated from it is the "Maximum Daily Concentration", It is identified as "Daily Maximum" under "Other Limits" in Part 1 of the. permit, Part II Page 13 of 14 d The "average annual concentration," other than for fecal co-iformbacteria, 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 1 of the permit:. 7 Other The "daily minimum concentration" (for dissolved oxygen only is the minimum allowable a .mount of dissolved oxygen required to be available in the effluent prior to discharge. It is identified as "Daily Minimum" under "Other Limits" in Part I11 of the permit. Yments Plow, (MGD): 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 r"instantaneous flow measurement" is a measure of flow taken at the ti of sampling, when both the sample and flow will be representative of the totaI . discharge. Types o Ales 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. 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 Part II Page 14 of 14 ulation 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 anti_log 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). 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. 10. Calendar Day A calendar day .s 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. Hazardous Substance. A hazardous substance means any substance designated under 40 CF. Part 116 pursuant to Section 311 of the Clean Water Act. 1.2, Toxic Pollutant A toxic pollutant is any pollutant listed as toxic under Section 307(a)(1) of the Clean Water Act, Revised 6/89 PART III OTHER REQUIREMENTS A. Previous Permits All previous State water quality permits issued tothis facility, whether for construction or operation. or discharge, are, hereby revoked by issuance of this permit. The. conditions, requirements, terms, and provisions of this permit authorizing discharge under the National Pollutant Discharge Elimination System govern discharges from this facility. B. Construction No construction of wastewater treatment facilities or additions thereto shall he begun until Final Plans. and Specifications have been submitted to the Division of Environmental Management and written approval and Authorization to Construct has been issued. C. Ceitiprator Pursuant to Chapter 90A-44 of North Carolina General Statutes, the permittee shall employ a certified. wastewater treatment plant operator in responsible charge (ORC) of the wastewater treatment facilities. Such operator must hold a certification of the grade equivalent to or greater than the classification assigned to the wastewater treatment facilities. The permittee shall notify the Division's Operator Training and Certification Unit within five days of any change in the ORC status.
