Ron °Boone of the Winston Salem Regional Office (WSRO) of the North Carolina Division of Water
Resources (DWR or the Division)- conducted a compliance evaluation inspection of the Boonville Wastewater
Treatment Plant on December6, 2016. The assistance and cooperation of Jeff Jones,Operator in Responsible Charge
(ORC), was greatly appreciated. An inspection report is attached for your records` and the inspection findings are
summarized below.
The Boonville Wastewater Treatment Plant is located at 456 Lon Avenue, at approximate coordinates
36.246177°, -80.707273°, in Boonville, Yadkin County, North Carolina. The Town of Boonville is authorized to operate
this 0.2 million -gallon -per -day (MGD) wastewater treatment plant, which consists of a bar screen, splitter box,
comminutor, aeration basins, secondary clarifiers, UV disinfection, digesters, 'sludge drying beds, and flow
measurement, and discharge treated effluent from outfall 001 of said treatment works, which is located approximately
250 feet east of the treatment works at approximate coordinates 36.246536°,.-80.706452°, into Tanyard Creek, which
is currently classified as Class C waters and is located in the Yadkin Pee -Dee River Basin.
SITE REVIEW
Mr. Boone reviewed the entire plant with Mr. Jones. Everything was in good condition and well maintained.
The effluent was clear and there was no foam at the discharge point into Tanyard Creek. The discrepancies Mr. Boone
noted are as follows:
As also noted in last year's inspection, influent sampling is not flow proportional as required by the
permit. There is no influent flow meter. The Town may wish to request exemption from this
requirement from the Division. To do so, please send us a letter, requesting this exemption with
sufficient justification.
DOCUMENTATION REVIEW
All documentation for the plant was reviewed, including operator visitation logs, operation and maintenance
logs, laboratory bench and field sheets, discharge monitoring reports, chains of custody, and contract laboratory
reports. No discrepancies were noted. All required records were present, readily available, and complete.

There were no other discrepancies noted. Mr. Jones and his operators are doing a good job operating and
maintaining the plant. Please keep up the excellent work in ensuring the plant is properly operated and maintained and
meeting all the terms and conditions of the permit.
Please contact us regarding the flow proportional composite influent sampling within 30 days of receiving
this letter so we can determine the way forward. Please remember that in accordance with NC General Statute 143-
215.6A, violations of the permit are subject to enforcement actions not to exceed $25,000 per day, per violation.
If you have any questions regarding the inspection or this letter, please do not hesitate to contact Mr. Boone
or me at 336-776-9800. Thank you for your cooperation in this matter.
Sincerely,
