Definitions a. The monthly average, other than for fecal colifarm bacteria, is the arithmetic mean of all the composite samples collected in a one - month period. The monthly average for fecal coliform bacteria is the geometric mean of samples collected in a one -month period. b. The weekly average, other than for fecal coliform bacteria, is the arithmetic mean of all the composite samples collected during a one -week period. The weekly average for fecal coliform bacteria is the geometric mean of samples collected in a one -week period. c. Flow, M /day (MGD): The flow limit expressed in this permit is the 24 hour average flow, averaged monthly. It is determined as the arithmetic mean of the total daily flows recorded during the calendar month. d. Arithmetic Mean: The arithmetic mean of any set of values is the summation of the individual values divided by the number of individual values. M 5 Part T Permit No. NC g• 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 equiva- lent 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). Composite Sample: A "°composite sample" is any of the following: (1) Not less than four influent or effluent portions collected at regular intervals over a period of 24 hours and composited in proportion to flow. 2) Not less than four equal volume influent or effluent portions collected over a period of 24 hours at intervals proportional to the flow. (3) An influent or effluent portion collected continuously over a period of 24 hours at a rate proportional to the flow. Grab Sample: A grab sample" is a single influent or effluent portion which is not a composite sample. The sample(s) shall be collected at the period(s) most representative of the total discharge. 4. Test Procedures Test procedures for the analysis of pollutants shall conform to the EMC regulations published pursuant to N. C. G.

The discharge of any pollutant identified in this permit more frequently than or at a level in excess of that authorized shall constitute a violation of the permit. Any anticipated facility expansions, production increases, or process modifications which will result in new, different, or increased discharges of pollutants must be reported by submission of a new NPDES application or, if such changes will not violate the effluent limitations specified in this permit, by notice to the DEM of such changes. Following such notice, the permit may be modified to specify and limit any pollutants not previously limited. 2. Non compliance Notification If, for any reason, the permittee does not comply with or will be unable to comply with any effluent limitation specified in this permit, the per- mittee shall provide the Division of Environmental Management with the following information, in writing, within five (5) days of becoming aware of such condition: a. A description of the discharge and cause of noncompliance; and b. The period of noncompliance, including exact dates and times; or, if not corrected; the anticipated time the noncompliance is expected to continue, and steps being taken to reduce, eliminate and prevent recurrence of the noncomplying discharge. Facilities Operation The permittee shall at all times maintain in good working order and operate as efficiently as possible all treatment or control facilities or systems installed or used by the permittee to achieve compliance with the terms and conditions of this permit. 4. Adverse Impact The permittee shall take all reasonable steps to minimize any adverse impact to navigable waters resulting from noncompliance with any effluent limitations specified in this permit, including such accelerated or additional monitoring as necessary to determine the nature and impact of the noncomplying discharge. 5.

Industrial Pretreatment Standards Permittee shall require any industrial dischargers into the permitted system to meet Federal Pretreatment Standards (40 CFR, Part 403 ) promulgated in response to Section 307(b) of the Act. The permittee shall provide semi-annual reports to the permitting agency regarding the pre-treatment requirements which have been imposed on each major contri- buting; industry and the results achieved therefrom. Other information may be needed regarding new industrial discharges and this will be requested from the permittee after the permitting agency has received notice of the new industrial discharge. A major contributing industry is one that: (1) has a flow of 50,000 gallons or more per average work day; (b) has a flow greater than five percent of the flow carried by the municipal system receiving the waste; (c) has in its, waste a toxic pollutant in toxic amounts as defined in standards issued under Section 307(a) of the Act; (d) has significant impact either singly or in combination with other contributing industries, on the treatment works or the quality of its effluent. Any change in the definition of a major contributing industry as a result of promulgations in response to Section 307 of the Act shall become a part of this Permit. M 12 PART III PART III OTHER T EQtiIFEI;SNTS ui.rements for Effluent Li al ns on Pollutants Attributable to Permet No. NC Effluent li.mi.tatins from this discharger are listed in Part I of this Vermit. It is apparent that other pollutants attributable to inputs from major contributing industries using the municipal system may also he present in the permittee's discharge. At such time as sufficient information becomes available to establish limitations for such pollutants, this permit may be revised to specify effluent limitations for any or all of such other pollutants in accordance with best practicable technology or water quality standards. 2. Under no circumstances shall the permittee allow introduction of the following wastes into the waste. treatment system: a. Wastes which create a fire or explosion hazard in the treatment works. b. Wastes which will cause corrosive structural damage to treatment works. Solid or viscous substances mounts which cause obstruct'.on;s tc the flow in sewers or interference with the proper operation of the treatment works. d. Wastewaters at a flow rate and/or pollutant discharge rate which is excessive over relatively short time periods so as to cause a. loss of treatment efficiency. e. Heat in amounts which will inhibit biological activity in the treatment works resulting in interference but in no case heat in such quantities 0 0., that the temperature at the treatment works influent exceeds 40 C (104 F) unless the works are designed to accomodate such heat. (After August 25, 1981) With regard to the effluent requirements listed in Part I of this perm,t, it may be necessary for the permittee to supplement the requirements of the Federal Pretreatment Standards (40 CFR, Part 403) to ensure compliance by the permittee with all applicable effluent limitations. Such actions by the permittee may be necessary regarding some or all of the major contri- buting industries discharging to the municipal system. The permittee shall require each major contributing industry subject to pre-treatment standards or any other applicable requirements promulgated pursuant to Section 307 of the Act to submit to the permittee periodic notice (at intervals not to exceed 9 months) regarding specific actions taken to achieve full compliance with the requirements of Section 307. Starting on the permittee shall submit semi-annually to the permit issuing authority a report summarizing the progress of all known major contributing industries subject to the requirements of Section 307 towards full compliance with such requirements. Such report shall include at least the following .information: PART III Permit No. NC a. A narrative summary of actions taken by the permittee to ensure that all major contributing industries comply with the requirements of Section 307. b. The number of major contributing industries using the treatment works, divided into SIC group categories. c. The number of major contributing industries in full compliance with the requirements of Section 307, or not subject to these requirements (e.g., discharge only compatible pollutants). d. A list identifying by name those major contributing industries presently in violation of the requirements of Section 307. 4. Immediately upon issuance of this permit, the permittee shall establish and implement a procedure to obtain from all major contributing indus- tries specific information on the quality and quantity of effluents intro- duced by such industrial users. The following information shall be reported to the permitting agency on a quarterly basis beginning ; quarterly reports reflecting no change from the previous quarter may simply relate this fact, without submitting repetitive data. a. Section IV, Standard Form A shall be completed and submitted for each major contributing industry. b.. Information on the municipal facility as a whole is to be reported on the monthly Monitoring Report Form (DEM - No. MR 1.0, 1.1, 1.2, and 1.3). Once the specific nature of industrial contributions has been identified, data collection and reporting requirements may be levied for other parameters in addition to those included on. Form (DEM No. 1.0, 1.1, 1.2, and 1.3). 5. Based on the information regarding industrial inputs reported by the permittee pursuant to the preceding paragraph, the permittee will be notified by the permitting authority of the availability of industrial effluent guidelines on which to calculate allowable inputs of incompatible pollutants based on BPT for each industry group. Copies of guidelines will be provided as appropriate. Not later than 120 days following receipt of this information, the permittee shall submit to the permitting authority calculations reflecting allowable inputs from each major con- tributing industry. The permittee shall also require all such major contributing industries to implement necessary pre-treatment requirements (as provided for in 40 CFR, Part 403), providing the permitting authority with notifications of specific actions taken in this regard. At that time, the permit may be amended to reflect the municipal facility's effluent requirements for incompatible pollutants. M '14 PART III Permit No. NC B. Previous Permits All previous State water quality permits issued to this 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 governs discharges from this facility. Construction No construction of wastewater treatment facilities or additions thereto shall be 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. If no objections to Final Plans and Specifications has been made by the DEM after 30 days following receipt of the plans or issuance of this permit, whichever is latter, the plans may be considered approved and construction authorized. D. Certified Operator Pursuant to Chapter 90A of North Carolina General Statutes, the permittee shall employ a certified wastewater treatment plant operator in responsible charge of the wastewater treatment facilities. Such operator must hold a certification of the grade equivalent to the classification assigned to the wastewater treatment facilities.
