DANIEL SMITH Director NORTH CAROLINA Environmental Quality December 29, 2021 Mr. Benjamin White General Manager Westrock Kraft Paper LLC - Roanoke Rapids Mill 100 Gaston Road Roanoke Rapids, NC 27870 Subject: Compliance Evaluation Inspection Westrock Kraft Paper LLC - Roanoke Rapids Mill WWTP Permit No. NC0000752 Northampton County Dear Mr. White: On November 18, 2021, Cheng Zhang of the Raleigh Regional Office (RRO) conducted a compliance evaluation inspection of the subject facility. The assistance provided by Mr. Chris William, the operator in responsible charge (ORC), Mr. Matt Upton, the backup ORC, and Mr. Paul Kinnin, was appreciated as it facilitated the inspection process. The inspection report is attached. The following observations were made: Westrock Kraft Paper LLC - Roanoke Rapids Mill WWTP is permitted to discharge at a rate of 28.0 MGD and consist of: mechanical bar screen, primary clarifier, emergency holding pond, sludge lagoon, aeration basin, and three stabilization ponds. The plant discharges to Roanoke River, a Class C water in the Roanoke River basin. 1. Current permit expires on March 31, 2022. Renewal application was received by the Division on October 29, 2021. Sludge handling facility is not listed as treatment unit, but covered under landfill permit WQ0000436. 2. All treatment units were found operable, except one of the two sludge screen thickeners (offline for repair) at the time of inspection. The primary clarifier was inspected and maintained during the plant's annual Cold Mill Outrage (scheduled annual maintenance of the entire plant) in October 2021. The traveling porting of the mechanical bar screen was repaired in November 2021 right before the inspection. 3. Process wastewater is pumped to the primary clarifier, where solids settle. 4. Sludge from the primary clarifier is dewatered at the sludge handling facility, two trains NOR�D_E �eeabnenl al EnNrvnmenlel5uelily North Carolina Department of Environmental Quality I Division of Water Resources Raleigh Regional Office 13800 Barrett Drive I Raleigh, North Carolina 27609 919.791.4200 DocuSign Envelope ID: B2714399-8090-4308-852D-ED959BA31E45 of screen thickeners and screw presses, and chemical feed system are available. One screen thickener was offline for repair at the time of inspection. Dewatered sludge is disposed at the onsite landfill. Leachate from the landfill and the old sludge pond flows by gravity into the aeration basin and is treated along with the effluent from the primary clarifier. 5. Effluent from the clarifier is further treated at the aeration basin. All 31 aerators were in operational condition. Numbers of aerators on line was controlled by the DO level in the basin. 6. Effluent from the aeration basin is further treated in the three stabilization ponds before being discharged to the river. 7. The ORC maintains a daily logbook. Lab results, chain -of -custody forms, and Discharge Monitoring Reports (DMRs) were complete and current, kept in good order and ready for review. March and August 2021 DMR data were compared to lab bench sheets; no data transcription errors were noted 8. The laboratory on site is certified to analyze most permit parameters (lab cert. no. 183). Toxicity, nutrients, and copper are sent to private labs for analysis. A cursory review of the laboratory noted buffers and standard solutions were within manufacturer expiration dates. The sample storage refrigerator and BOD incubators, were found to be compliant with temperature requirements. Field meter calibration records were reviewed. 9. The right of way to Outfall 001 was well maintained. The effluent was observed to be clear and free of solids. No visible impacts were noted immediately downstream the effluent pipe. Outfall 002 was also maintained and accessible. The overall condition of the facility is compliant with Division standards. If you have any questions regarding the attached reports or any of the findings, please contact Cheng Zhang at: (919) 791-4200 (or email: cheng.zhang@ncdenr.gov).
