SUBJECT: Compliance Evaluation Inspection

NPDES Permit # NCO075515
Wilkes County
Dear Mr. Spicer:
Donald R. van der Vaart
Secretary
A Compliance Evaluation Inspection was performed by George Smith on October 7, 2015. Mr. Tommy
Spicer, ORC was present at this inspection. The inspection is comprised of an overall evaluation of the
facilities equipment, and capability to produce an effluent discharge that meets NPDES permit limits.
Permit
Your NPDES permit became effective on October 1, 2013 and expires on September 30, 2018.
The eDMR requirement is included in the permit under Section A.(3). Wilkes County Schools did register
for eDMR, and is working on eDMR submission. Please remember that both paper and eDMR submission
are required at this time.
Records & Reports
Mr. Spicer maintains an operator log, which documents sampling, analysis, Operations & Maintenance,
and his visitations. The records are well organized and maintained in a file cabinet. All are in excellent
order.
Facility Site Review
There are two sandfilters, each one has a 6-inch main line. There are eight 4-inch dosing lines in each
sandfilter. The beds appear to need more sand.
The tablet chlorinator uses two tubes of Norweco calcium hypochlorite tablets. The tablet dechlorinator
uses two tubes of Norweco sodium bisulfite tablets.
There are two small trees adjacent to the beds that need to be removed.
Flow Measurement
The flow is measured using the intake water meter.

Laboratory
Wilkes County Schools is an approved field certified lab (# 5406).
The pH calibration is performed with a SensIon 156, using a three-point calibration method (buffers 4, 7,
10), and a midrange check at 7.0. The calibration is recorded.
Temperature is measured with the pH meter and is calibrated, documented, and is traceable to NIST.
The Dissolved Oxygen is measured with an YSI, Model 50B meter, and the air calibration is performed.
The Total Residual Chlorine is measured with a Hach DR2700 spectrophotometer. The 5-point annual
calibration is scheduled to be performed during October 2015.
Effluent/Receiving Waters
The effluent from the sandfilter is discharged through a tablet chlorinator and tablet dechlorinator. It then
goes to a manhole just outside the fence on top of the bank followed by a second manhole down along a dirt
road, which then discharges to an unnamed tributary to Warrior Creek, Class WS-IV waters.
Operations & Maintenance
The facility is satisfactorily operated and maintained. Mr. Tommy Spicer, Grade II is the ORC; Mr. Stacy
Higgins, Grade II, Back-up ORC.
Self -Monitoring Program
Grab samples are taken at the manhole, which is adjacent to the gravel road.
A review of the monthly self -monitoring reports from January 2015 through July 2015 showed no limit
violations.
The compliance evaluation inspection is satisfactory. If you have any questions please contact George
Smith or me at [phone].
