Permit Issuing Authority The Director of the Division of Environmental Management. u•aviol "M •, Means the Division of Environmental Management, Department of Environment, Health and Natural Resources. 3. EMC Used herein means the North Carolina Environmental Management Commission. 4. Act or "the Act" The Federal Water Pollution Control Act, also known as the Clean Water Act, as amended, 33 USC 1251, et. seq. 5. Mass/Day Measurements 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 sampled and measured, divided by the number of daily discharges sampled 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 "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 sampled 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 sampled 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. Part H Page 2 of 14 6. ' Concentration Measurement a. The "average monthly concentration," other than for fecal coliform bacteria, is the sum. of the concentrations of all daily discharges sampled 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" 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. 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 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. e. The "daily average: concentration" (for dissolved oxygen) is the minimum allowable amount of dissolved oxygen required to be available in the effluent prior to discharge averaged over a calendar day. If only one dissolved oxygen sample is taken over a'calendar day, the sample is considered to be the "daily average concentration" for the discharge. - It is identified as "daily average" in the text of Part I. f. The "quarterly average concentration" is the'average of all samples taken over a calendar quarter. It is identified as "Quarterly Average Limitation" in the text of Part I of the permit. g. A calendar quarter is defined as one of the- following distinct periods: January through March, April through June, July through September, and October through December. Part II Page 3 of 14 a. Flow; (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 "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. c. A "continuous flow measurement" is a measure of discharge flow from the facility which occurs continually without interruption throughout the operating hours of the facility. Flow shall be monitored continually except for the infrequent times when there may be no flow or for.infrequent maintenance activities on the flow device: a. Composite Sample: A composite sample shall consist of: (1), a series of grab samples collected at equal time intervals over a 24 hour period of discharge and combined proportional to the rate of flow ,measured at the time of individual sample collection, or (2) a series of grab samples of equal volume collected over a 24 hour period with the time intervals between samples determined by a preset number of gallons passing the sampling point. Flow measurement between sample intervals. shall be determined by use of a flow recorder and totalizer, and the present.gallon interval between sample collection fixed at no greater than 1/24 of the expected total daily flow at the treatment system, or (3) a single, continuous sample collected over a 24 hour period proportional to the rate of flow. In accordance with (1) above, the time interval between influent grab samples shall be no greater than once per hour, and the time interval between effluent grab samples shall be no greater than once per -hour except at wastewater treatment systems having a detention time of greater than 24 hours. In such cases, effluent grab samples may be collected at time intervals evenly spaced over the 24 hour period which are equal in number of hours to the detention time of the system in number of days. However, in no case may the time interval between effluent grab samples be greater than six (6) hours nor the number of samples less than four (4) during a 24 hour sampling period. 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. Grab samples must be representative of the discharge or the receiving waters. 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). Part II Page 4 of 14 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. 10. Calendar Day 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 maybe used for sampling. 11. Hazardous Substance A hazardous substance means any substance designated under 40 CFR Part 116 pursuant to Section 311 of the Clean Water Act. 12. Toxic Pollutant A toxic pollutant is any pollutant listed as toxic under.Section 307(a)(1) of the Clean Water Act. SECTION B. GENERAL CONDITIONS The permittee must comply with all conditions of this permit. Any permit noncompliance constitutes a violation of the Clean Water Act and is grounds for enforcement action; for permit termination, revocation and reissuance, or modification; or denial of a permit renewal application. a. The permittee shall comply with effluent standards or prohibitions established under section 307(a) of the Clean Water Act for toxic pollutants and with standards for sewage sludge use or disposal established under section 405(d) of the Clean Water Act within the time provided in the regulations that establish these standards or prohibitions or standards for sewage sludge use or disposal, even if the permit has not yet been modified to incorporate the requirement. b. The Clean Water Act provides that any person who violates a permit condition is subject to a civil penalty not to exceed $25,000 per day for each violation.

Part II Page 8 of 14 2. Proper Q12eration and Maintenance The permittee shall at all times properly operate and maintain all facilities and systems of treatment and control (and related appurtenances) which are installed or used by the permittee to achieve compliance with the conditions of this permit. Proper operation and maintenance also includes adequate laboratory controls and appropriate quality assurance procedures. This provision requires the operation of back-up 'or auxiliary facilities or similar systems which.are installed by a permittee only when the operation is. necessary to achieve compliance with the conditions of the permit. I Need to Halt or Reduce not a Defense It shall not be a defense for a permittee in an enforcement action that it would have been necessary to halt or reduce the permitted activity in order to maintain compliance with the condition of this permit. 4. Bypassing of Treatment Facilities a. Definitions (1) 'Bypass" means the known diversion of waste streams from any portion of a treatment facility including the collection system, which is not a designed or established or operating mode for the facility. (2) "Severe property damage" means substantial physical damage to property, damage to the treatment facilities which causes them to become inoperable, or substantial and permanent loss of natural resources which can reasonably be expected to occur in the absence of a bypass. Severe property damage does not mean economic loss caused by delays in production. b. Bypass not exceeding limitations. The permittee may allow any bypass to occur which does not cause effluent limitations to be exceeded, but only if it also is for essential maintenance to assure efficient operation. These bypasses are not subject to the provisions of Paragraphs c. and d. of this section. c. Notice (1) Anticipated bypass. If the permittee knows in advance of the need for a bypass, it shall submit prior notice, if possible at least ten days before the date of the bypass; including an evaluation of the anticipated quality and affect of the bypass. (2) Unanticipated bypass. The permittee shall submit notice of an unanticipated bypass as required in Part II, E. 6. of this permit. (24 hour notice). d. Prohibition of Bypass (1) Bypass is prohibited and the Permit Issuing Authority may take enforcement action against a permittee for bypass, unless: (A) Bypass was unavoidable to prevent loss of ilife, personal injury or severe property damage; (B) There were no feasible alternatives to the bypass, such as the use of auxiliary treatment facilities, retention of untreated wastes or maintenance during normal Part II Page 9 of 14 periods of equipment downtime. This condition is not satisfied if adequate backup equipment should have been installed in the exercise of reasonable engineering judgment to prevent a bypass which occurred during normal periods of equipment downtime or preventive maintenance; and (C) The permittee submitted notices as required under Paragraph c. of this section. (2) The Permit Issuing Authority may approve an anticipated bypass, after considering its adverse affects, if the Permit Issuing Authority determines that it will meet the three conditions listed above in Paragraph d. (1) of this section. 5. upsets . a. Definition. "Upset " means an exceptional incident in which there is unintentional and temporary noncompliance with technology based permit effluent limitations because of factors beyond the reasonable control of the permittee. An upset does not include noncompliance to the extent caused by operational. error, improperly designed treatment facilities,, inadequate treatment 'facilities, lack of preventive maintenance, or careless or improper operation. b. Effect of an upset. An upset constitutes an affirmative defense to an action brought for noncompliance with such technology based permit effluent limitations if the requirements of paragraph c. of this condition are met. No determination made during administrative review of claims that noncompliance was caused by upset, and before an action for noncompliance, is final administrative action subject to judicial.review. c. Conditions necessary for a demonstration of upset. A permittee who wishes to establish the affirmative defense of upset shall demonstrate, through properly signed, contemporaneous operating logs, or other relevant evidence that: (1) An upset occurred and that the permittee can identify the cause(s) of the upset; (2) The permittee facility was at the time being properly operated; and (3) The permittee submitted notice of the upset as required in Part II, E. 6.
