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

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).
Sincerely,

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 land fill
permit WQ0000436.
Treatment system consists of influent pump station with bypass line to emergency pond, primary
clarifier, aeration basin, three stablization ponds, and sludge lagoon, sludge from clarifier is
dewatered with two screen thickeners and two screw presses. Dewatered sludge is disposed of at the
onsite landfill. Leachate from the landfill and effluent from the sludge lagoon are treated at the
aeration basin.
Record keeping was excellent, ORC logbook, flow meter calibratio, and DMR/lab reports were kept at
least 5 years back.
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.
