SUBJECT: Compliance Evaluation Inspection AUG 14 2018

NPDES Permit No. NC0035149 permitting Section
Watauga County
Dear Mr. Harrill,
On August 2, 2018, Kelli Park and Gary Hudson, of this office, met with Josh Cagle
to perform a Compliance Evaluation Inspection on the Seven Devils Resort wastewater
treatment system. Mr. Cagle was filling in for the operator in responsible charge (ORC);
Steve Taylor. This type of inspection consists of two basic parts: an in-office file review
and an on-site inspection of the treatment facility. The attached EPA inspection form
notes the areas that were evaluated for this inspection. The findings and observations
are outlined below:
I
I. Permit
The NPDES permit became effective October 1, 2017, and expires September 30, 2022.
The facility had a copy of the permit available during the inspection.
II. Self-Monitoring Program
A review of the monthly discharge monitoring reports (DMR) for the period January 2017
through August 2018 showed that the facility was not in compliance with all permit limits.
While they were previously addressed before this letter, they are also listed in the table
below.

Grab samples are taken by the ORC at the effluent outfall. These samples are put on ice
and analyzed by Water Quality Labs in Banner Elk.
III. Records/Reports
The permit and visitation log are located on site and show visitation times and plant
conditions. Chain of custody forms are in good order. All required monitoring was
performed per the frequencies specified in the NPDES permit. Miss Park noted no data
transcription discrepancies from bench sheets to DMRs in her documentation review.
Water Quality Labs maintains the documentation.
' IV. Flow Measurement
The flow is measured continuously by a v-notch weir with an ultrasonic sensor. The device
was calibrated in July 2018.
V. Operations and Maintenance
The wastewater treatment plant appeared to be well maintained and operated. The ORC
and backup ORC are sufficiently qualified to be running the plant.
Mr. Cagle mentioned that the diffusers in the plant were recently cleaned to improve the
dissolved oxygen levels in the aeration basin.
VI. Facility Site Review
All components of the 0.020 million gallons per day facility appeared to be functioning
properly. The aeration basin had a light brown color and a good earthy odor. All blowers
were functioning properly and there were no dead spots. The secondary clarifier looked
clean, however it was discharging effluent with traces of pin floc. Effluent is disinfected
with chlorine tablets and de-chlorinator tablets before leaving the plant.
Mr. Cagle believes the pin floc to be an inflow and infiltration issue from the heavy rains
over the two weeks prior to the inspection. He reported that the plant will normally
fluctuate around 6,000-11,000 gallons of wastewater a day, but due to the rain the plant
was reading 16,000 gallons of wastewater the day of the inspection and 27,000 gallons
the next day (August 3rd). When Miss Park spoke with him on August 6th Mr. Cagle
reported that there was no pin floc in the effluent, and that it was clear.

• Seven Devils Resort WWTP,August 2,2018
The blower house structure is weak and missing large sections of wall around the blowers.
It is recommended that this is repaired or a new structure is built to protect the blowers
and be safer for the operators.
A few areas in the metal walkway over the plant were weak. It is recommended that those
sections be replaced with new metal panels for safety purposes.
VII. Effluent/Receiving Waters
The effluent from the facility was clear, but had pin floc in it the day of the inspection.
Effluent is discharged into an unnamed tributary to the Watauga River, class C; trout
waters in the Watauga river basin. There was no odor associated with the effluent.
VIII. Sludge Maintenance and Handling
Sludge was reported to be pumped about once a year due to low flow in the plant. Triple
T Plumbing pumps the sludge and the time, date, and how much was pumped is recorded
into the operator log on site. It is also documented at Water Quality Labs.
IX. Conclusions
The compliance evaluation inspection is satisfactory. Mr. Cagle maintains and operates
the facility in a good manner. His efforts to comply with the permit are appreciated. If you
have any questions regarding the inspection or this report, please contact Kelli Park or
me at [phone].
Sincerely,
Sherri V. Knight, P.E.
