NC0001406 Harnett County William G. Ross Jr., Secretary Gregory. J. Thorpe, Ph.D. Acting Director Division of Water Quality Dear Mr. Averey: Enclosed is a copy of the Compliance Evaluation Inspection conducted Septeniber'25, 2001. The ,manufacturing facility for Swift Textiles . has„closed permanently and the only wastewater discharging into the wastewater plant is domestic from residential areas in the Town of Erwin. 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 cooperation of Mr. Waldo.Faircloth, former head boiler operator was appreciated. As a reminder please notify DWQ staff within 48 hours or the next working day when discharge will cease. DWQ• staffwould like to perform a closeout inspection,to ensure preservation of our Waters of the State. Please review the attached report. If you or your staff have any questions do not hesitate to contact me at (910)486-1541. Sincerely, Belinda S.

The influent flow is pumped into the plant by variable pace drive pumps which operate when the flow reaches a certain level they begin pumping. The two (2) pumps alternate. 2. The automatic bar screen and grit removal system appeared to be operational. The screenings and grit are presently stored in a compartment behind the bar screen/grit removal system. The screenings and grit should be placed in a container and properly disposed of. 3. The two aeration basins were operational. Plans are to shut one basin down soon and operate the facility with one aeration basin: - 4. Clarifier #1 is not operating due to the decreased amount of flow into the plant. Clarifier #2 is in. operation with < (less than) 1 foot of sludge depth: At the time of the inspection there did not appear to be an effluent flow over the weirs. The effluent flows. through cascade aeration before it is discharged directly to the Cape Fear River. 5. The facility collects a composite sample over an 8 hour period Monday .through Friday and it is placed in a refrigerator for storage until they are shipped to the commercial laboratory (Environment 1) for analyses of the NPDES permit required parameters. 6. The Polysonics effluent flow meter was calibrated October 27, 2000 by J S Dismuke. It is advisable that the flow meter calibration document contain the % error before and after calibration in the future by the technician. 7. The, facility has a holding tank for biosolids and two (2) sludge thickening tanks. The holding tank has approximately 1/4 capacity of sludge. One thickening tank is empty and the other has approximately . 250,000 gallons of sludge in it. .Records for sludge disposal revealed that the most recent haul was April 2001; with '775,000 gallons of sludge that were land applied by the contract. company Synagro under permit # WQ 0006298. Plans . are to remove all solids, from the thickening tank and use the holding tank for sludge. 8. . The filter press is operational and onsite but does not appear to have been'utilized recently.. 9. A discharge from pipe # 002 has ceased with the closing of the water plant facility. The discharge from this pipe was backwash water from the filters. 10. The followingNPDES 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". 11. Laboratory records for the month March. and April2001, were reviewed and compared to Discharge Monitoring Reports (DMRs). The records reviewed appeared to be accurate. Mr. Avery Page 4 October 4, 2001 12. A compliance evaluation analysis report for the period August 2000 through July 2001 did not reveal any monthly violations.
