MONITORING AND REPORTING 1. Representative sanipling Samples and measurements taken as required herein shall be representative of the volume and nature of the monitored discharge. 2. Reporting Monitoring results obtained during the previous month(s) shall be summarized for each month and reported on a Monthly Monitoring Report Form (DEM No. MR 1.0, 1.1, and 1.4) , postmarked no later than the 45th day following the completed reporting period.

Definitions a. The monthly average, other than for fecal coliform 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 conform 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 Part. Permit No. NC e. 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). f. Composite Sample: A "composite sample" is any of the following: (1) (2) (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. Not less than four influent or effluent portions collected at regular intervals over a period of 24 hours and composited in proportion to flow. Not less than four equal volume influent or effluent portions collected over a period of 24 hours at intervals proportional to the flow. Test Procedures Test procedures for the analysis of pollutants shall conform to the EMC regulations published pursuant to N. C. G. S. 143-215.63 et seq, The Water and Air Quality Reporting Act, and to regulations published pursuant to Section 304(g), 33 USC 1314, of the Federal Water Pollution Control Act, As Amended, and Regulation 40 CFR 136. 5. Recording Results For each measurement or sample taken pursuant to the requirements of this permit, the permittee shall record the following information: a. The exact place, date, and time of sampling; b. The dates the analyses were performed; and c. The person(s) who performed the analyses. M6 PART I Perri i`io. NC Additional Monitoring by Permi ttee If the perrnittee monitors any pollutant at the location(s) designated herein more frequently than required by this permit, using approved analytical methods as specified above, the results of such monitoring shall be included in the calculation and reporting of the values required in the Monthly Monitoring Report Form (DEM No. MR 1.0, 1.1, and 1.4) Such increased frequency shall also be indicated.

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. Bypassing Any diversion from or bypass of facilities necessary to maintain compliance with the terms and conditions of this permit is prohibited, except (i) where M8&I7 PART II Permit No. NC unavoidable to prevent loss of life or severe property damage, or (il) where excessive storm drainage or runoff would damage any facilities necessary for complaince with the effluent limitations and prohibitions of this permit. All permittees who have such sewer bypasses or overflows of this discharge shall submit, not later than six months from the date of issue of this permit, detailed data or engineering estimates which identify: a. The location of each sewer system bypass or overflow; b. The frequency, duration and quantity of flow from each sewer system bypass or overflow.

Removed Substances Solids, sludges, filter backwash, or other pollutants removed in the course of treatment or control of wastewaters. shall be disposed of in a manner such as to prevent any pollutant from such materials from entering waters of. the State or navigable waters of the United States. 7. Power Failures The permittee is responsible for maintaining adequate safeguards to prevent the discharge of untreated. of inadequately treatedwastes during electrical power failures either by means of alternate power sources, standby generators or retention of inadequately treated efflu- ent. Should. the treatment works not include the above capabilities at time of permit issuance, the permittee must furnish within six months to the permitting authority, for approval, an implementation schedule for their installing, or documentation demonstrating that such measures are not necessary to prevent discharge of untreated or inadequately treated wastes. Such documentation shall include frequency and duration of power failures and an estimate of retention capacity of untreated effluent. '.

Based on the information regarding industrial inputs reported by the permittee pursuant to the preceding paragraph, the permittee wild 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 4o ), 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.
