Such discharges shall be limited and monitored' by the Permittee as specified below: EFFLUENT LIMITS MONITORING REQUIREMENTS PARAMETER CHARACTERISTICS Monthly Weekly Daily Measurement Sample Sample Parameter Code Average Average Maximum Frequency Type Location z Flow 50050 1.9 MGD Continuous Recording Influent or Effluent otal Monthly Flow (MG) 3 82220 Monitor and Report Monthly Recorded or Effluent Calculated OD 5-day, 20°C C0310 April 1— October 31) 4 5.0 mg/L 7.5 mg/L Daily Composite Influent & Effluent OD 5-day, 20°C C0310 November 1 — March 31 4 10.0 mg/L 15.0 mg/L 2/week 74 Composite Influent & Effluent SS otal Suspended Solids C0530 30.0 mg/L 45.0 mg/L 2/week 14 Composite Influent 8 Effluent mmonia (NH3 as N) C0610 ril 1 -October 31 1.0 mg/L 3.0 mg/L Daily Composite Effluent mmonia (NH3 as N) C0610 November 1 - March 31 2.0 mg/L 6.0 mg/L 2/week 14 Composite Effluent H 00400 Between 6.0 and 9.0 standard units Daily Grab Effluent issolved Oxygen (mg/L) 00300 Daily Average Z 6.0 mg/L Daily Grab Effluent Fecal Coliform 31616 eomehic mean 2001100 mL 4001100 mL 2/week 74 Grab Effluent Temperature (°C) 00010 Monitor and Report Daily Grab Effluent Conductivity (mohms/cm) 00094 Monitor and Report Daily Grab Effluent Total Residual Chlorine RC 6 50060 17 Ng/L Daily Grab Effluent KN (mg/L) 6 00625 Monitor and Report Weekly Composite Effluent 03-N + NO2-N (mg/L) 6 00630 Monitor and Report Weekly Composite Effluent N (mg/L) 3.6 C0600 Monitor and Report Weekly Composite Effluent 0M600 Monitor and Report (poundstmonth) Monthly Calculated Effluent N Load 3 33,070 poundslyear (annual mass loading)r Annually Calculated Effluent GY600 Total Phosphorus C0665 2.0 mg/L (Quarterly Average?

Submit discharge monitoring reports electronically using the NC DWR's eDMR application system. See section A. (8.). 2. U: Upstream at the culvert on NCSR 1158. D: Downstream at NCSR 1227. Stream samples shall be grab samples collected 3/Week from June to September and I/Week during the remaining months of the year. As a participant in the Lower Neuse River Basin Association, the instream monitoring requirements as stated above are waived. Should your membership in the association be terminated, you shall notify the Division immediately and the instream monitoring requirements specified in your permit shall be reinstated. 3. Total Nitrogen Load is the mass quantity of Total Nitrogen (TN) discharged in a given period of time and requires Total Monthly Flow (TMF). See condition A. (3.). Calculation of Total Nitrogen Loads. 4. The monthly average effluent BODS and Total Suspended Residue concentrations shall not exceed 15% of the respective influent value (85% removal). 5. Total Residual Chlorine compliance is required if chlorine or chlorine derivative is used for disinfection. The Division shall consider all effluent TRC values reported below 50 ug/l to be in compliance with the permit. However, the Permittee shall continue to record and submit all values reported by a North Carolina certified laboratory (including field certified), even if these values fall below 50 ug1I. 6. For a given wastewater sample, Total Nitrogen (TN) = TKN + (NO3-N + NO2-N) where TKN is Total Kjeldahl Nitrogen, and (NO3-N + NOz-N) is Nitrate and Nitrite Nitrogen. 7. Compliance with this limit shall be determined in accordance with conditions A. (4.) Annual Limits for Total Nitrogen. and A. (5.) Total Nitrogen Allocations. 8. The quarterly average for total phosphorus shall be the average of composite samples collected weekly during the calendar quarter (January -March, April -June, July -September, October -December). 9. Monitoring for Nickel shall be conducted in conjunction with the Chronic Toxicity monitoring. 10. Chronic Toxicity (Ceriodaphnia dubia) P/F at 90%: January, April, July, and October [see condition A. (2.)]. Toxicity monitoring shall coincide with metals monitoring. 11. The permittee shall perform three Effluent Pollutant Scans during the term of this permit [see A. (7•)]• 12. Effluent Total Hardness sampling shall be performed in conjunction with testing for hardness - dependent metals (cadmium, copper, lead, nickel, silver, and zinc). 13. The permittee shall sample instream hardness upstream of the facility's discharge. The sample shall be representative of the hardness in the receiving stream. If the permittee is a member of a monitoring coalition program, sampling for instream hardness may be waived as long as the monitoring coalition agrees to sample hardness at the nearest upstream location, at a minimum frequency of quarterly, and the permittee has obtained approval from DWR-NPDES Permitting Unit that the upstream station being monitored by the Coalition is representative of the receiving stream for this discharge. The permittee is responsible for submitting instream hardness test results with its permit renewal application package. If Coalition membership is cancelled or the Coalition terminates instream hardness sampling at the approved station, the permittee will immediately notify the Division and resume sampling for instream hardness upstream of its discharge. 14. 2/week sampling must occur on any two non-consecutive days during the calendar week. There shall be no discharge of floating solids or visible foam in other than trace amounts.
