SUBJECT: Compliance Evaluation Inspection
Town of Jefferson WWTP
NPDES Permit # NCO021709
Ashe County
Dear Mr. Church:
Donald R. van der Vaart
Secretary
A Compliance Evaluation Inspection was performed on the facility by George Smith on October 9, 2015. Mr. Tim
Church, ORC, Grade IV was present for the inspection. The inspection is comprised of an overall evaluation of the
facilities equipment, capability to meet effluent limits, and compliance with the NPDES permit.
Permit
Your new NPDES permit became effective September 1, 2011 and expires March 31, 2016.
It is recommended that the Town register for eDMR. It will be a permit requirement in your next permit cycle.
Please remember to submit your NPDES permit renewal application EPA Form 2A. Send to:

Records & Reports
The facility performs and documents process control of the following: microscopic examination, settleability, MLSS,
pH (clarifier, oxidation ditch, and digester), dissolved oxygen in the oxidation ditch, Sludge Volume Index (SVI), and
blanket height with a sludge judge. These records were in excellent order.
The Performance Annual Report for the calendar year 2014 was sent to the NPDES Unit on June 9, 2015.
Facility Site Review
There are four influent pumps (two-300gpm and two-400gpm).
The 3/8-inch automatic bar screen was properly operating.
The oxidation ditch components and rotating contactors are in good working order, and there is a good earthy odor.
The three rings of the ditch have sufficient dissolved oxygen. This treatment unit is performing very well.

The secondary clarifier's effluent over the weirs was clear. Both units were functioning very well, and were well
maintained. There was a very small amount of floating paper on the surface, which is discharged from the county jail.
The tertiary filter is producing a clear effluent. The unit is properly maintained. In fact, the water was clear.
The chlorine contact chamber contained a clear effluent with no solids present.
Flow Measurement
The flow is measured with a 90' V-notch sharp crested weir. A Chessel type flow recording device is used with a
seven day circular chart.
The calibration was performed and documented by the Town of Jefferson on July 28, 2015.
Laboratory
The municipal lab is field certified #5206, and performed the following: Total Residual Chlorine, Dissolved Oxygen,
pH, and temperature.
The total residual chlorine is performed using a Hach DR2500 spectrophotometer with the DPD method and using
the flow thru cell. The annual five point calibration is scheduled to be performed during October 2015.
The model `Hach One' pH meter is calibrated with a two -point buffer of 4 & 7 and check with a pH 10 buffer.
A calibration log was kept for pH and dissolved oxygen, and temperature, which is traceable to NIST.
Effluent/Receiving Waters
The effluent, which discharges to Naked Creek, Class C + waters, was crystal clear and had no color, solids, or odor.
The effluent showed no adverse to the stream.
Operations & Maintenance
The Class II facility was maintained by the following contingent: Tim Church, ORC, Grade IV and Fred Walters,
Back-up ORC, Grade II.
There were four biological rotators that had rebuilt drive motors. There are two remaining to be rebuilt.
The oxidation ditch is maintained at a MLSS of 2730 mg/L. The settleable solids are 42%. The Sludge Volume Index
(SVI) is 153.
Chlorine gas is used for disinfection. Anhydrous sodium metabisulfite is used for dechlorination, which is prepared
and dissolved in water as needed.
Self -Monitoring Program
The effluent is sampled by composite flow proportion method at 150 ml/10,000 gallons using Isco model 3710 ER
samplers with refrigerator. They are well maintained, clean tubing and temperature is 1°C.
All grab samples are taken at the end of the pipe 001 just before it discharges into Naked Creek, Class C waters.

A review of the monthly self -monitoring reports from January 2015 through July 2015 showed no limit violations.
Sludge Disposal
The Town is permitted to land apply the residuals. The digesters appeared to be functioning properly with
approximately volume 50% left to waste. The sludge dryer appears to be well maintained. The facility generates
approximately 50% Class A and 50% Class B residuals.
The compliance evaluation inspection is considered satisfactory. Mr. Church does a very good job maintaining the
POTW. If you have any questions please contact George Smith or me at [phone].

Reviewed sample date for both outfalls taken on 12/16/14 and 6/23/15. The data included
flow, temperature, pH. and COD. They also collected upstream and downstream
temperatures.
The facilitv also has the abilitv to discharge non -contact cooling water. air washers and
chillers and boiler blowdown to their pretreatment system. Exactly what is discharged to
surface waters and the pretreatment system is difficult to determine due to the old
