WWTP NPDES Permit No. NC0001406 Harnett County Dear Mr. Williams: Enclosed is a copy of the Compliance Evaluation Inspection conducted October 26.2000. • As part of the inspection a tour of the Wastewater Treatment Plant was conducted. All observations and recommendations are in Part D. Summary of Findings/Comments of this inspection report. The objective we should all be striving for is NPDES permit compliance which in turn will provide preservation of our receiving stream for generations to come. With your facility closing permanently, please notify DWQ staff within 48 hours or the next working day when discharge will cease. DWQ staff would like to perform a closeout inspection to ensure preservation of our receiving stream and environment. Please review the attached report.

The sulfuric acid tank located at the Headworks of the facility has a volume of 8000 gallons. The acid is used for pH adjustment. Ammonia (Urea) has not been used recently for treating the wastewater. 2. The automatic bar screen appeared to be operational with all screenings disposed of through the county landfill. 3. The grit removal system appeared to be operational with all grit disposed of through the county landfill. 4. The aeration basins appeared to be adequately treating the wastewater. All aerators were operational. The most recent Mixed Liquor Suspended Solids (MLSS) result was 4500 mg/L and a Dissolved Oxygen result of 4.0 mg/L. Polymer is added to the aeration basins to assist with solids settling in the clarifiers. 5. The clarifiers appeared to be operating adequately. They appeared to be clean and well maintained. The sludge depths were 5 feet in one and 4 feet in the other with a tank depth of 10 feet. 6. The effluent appeared to be free of solids. 7. A Sigma 8420 Dissolved Oxygen (DO) meter had been installed since the last inspection. The DO was reading 11.5 mg/L at the time of the inspection with a water temperature of 65 degrees C. The DO meter is located after the cascade aeration. The effluent flows through cascade aeration before it is discharged directly to the Cape Fear River. 8. The effluent flow meter was calibrated May 16, 2000 by J S Dismuke. It is advisablefthat the flow meter calibration document contain the % error before and after calibration in the future by the technician. 9. The effluent composite sampler refrigerator temperature was 1 degree C. The proper temperature for samples during compositing is 0 - 4 degrees C. 10. The facility has 2 holding tanks for biosolids. The holding tanks have a capacity of 1 million gallons. They tanks were approximately.1/z capacity of biosolids. Approximately 1 million gallons a month of biosolids are land applied under permit # WQ 0006298. The land application permit allows 2000 dry tons/year to 2880 acres. 11. The filter press is operational and a storage area for dewatered biosolids is on site. The filter press is used during wet seasons when biosolids cannot be applied to land. 12. Flow from pipe #'002 is backwash water from the filters when they are cleaned at the water plant facility. 13. The following NPDES permit required parameters are analyzed by facility staff: pH, Temperature, and Dissolved Oxygen. The commercial laboratory "Environment 1" analyzes all other required parameters with the exception of the Toxicity which is completed by the commercial laboratory "Tritest". 14. Laboratory records for the month January 2000 were reviewed and compared to Discharge Monitoring Reports (DMRs). The records reviewed appeared to be accurate. -continued- 15. A compliance evaluation analysis report for the period September 1999 through August 2000 did not reveal any monthly violations. 16. As a reminder as per our Administrative Code Section: 15A NCAC 2B .0506(b)(3)(F)(i)-the date on which collection of composite samples is commenced or data shall be entered onto the monitoring report form on the date that has the greater number of hours in it. The following examples will assist you in understanding the reporting date: a. If the composite sample is started on Tuesday, October 3, 2000 at 9:OOAM and the sample is withdrawn from the composite sampler on Wednesday, October 4, 2000 at 9:OOAM; the day with the greater number of hours in it is Tuesday, October 3, 2000. b. If the composite sample is started on Tuesday, October 3, 2000 at 6:OOPM and the sample is withdrawn from the composite sampler on Wednesday, October 4, 2000 at 6:OOPM; the day with the greater number of hours in it is Wednesday, October 4, 2000.
