Compliance Evaluation Inspection
Roanoke River Waste Treatment Plant
NPDES Permit No NCO024201
Halifax County
On January 23, 2018, Jason Robinson of the Raleigh Regional Office (RRO) conducted a compliance
evaluation inspection of the subject facility. The assistance provided by Mr Steven Ellis, Operator in
Responsible Charge (ORC) and Isabelle Field-Wilcoxon, Lab Supervisor was appreciated The
inspection report is attached. The following observations were made -
The facility is currently pennitted to discharge up to 8 34 MGD into Roanoke River, a class -C
water in the Roanoke River Basin The facility's monthly average flow for the 2017 calendar
year was approximately 3 0 MGD. The current pen -nit expired on March 31, 2017. A renewal
application was received in September 2016
2 The plant is classified as a WW -4 wastewater facility. Mr Steven Ellis is designated as the
primary Operator in Responsible Charge (ORC), and is a WW -4. Mr Timothy Skipper is
designated as the main backup Operator (bORC) and is also a WW -4 Daily operation log
books are detailed and are kept on-site going back at least three years
The laboratory was inspected in a cursory manner The facility analyzes BOD, COD, TSS,
Fecal Coliform ammonia nitrogen and total phosphorus, and is field certified for TRC, pH,
Temperature and DO (Certification #70) Log books were kept and showed that incubators are
kept at acceptable temperatures. pH buffers were within dates. Calibration logs were present
All other parameters are analyzed by Mentech, Inc Lab results, chain -of -custody forms, and
DMRs were complete and organized. September DMR data was compared to lab bench
sheets; no data transcription errors were noted Samples were observed to be kept at proper
temperature
