SUBJECT: Compliance Evaluation Inspection
Roaring River Chalets P
NPDES Permit No. NC0032158
Watauga County
Dear Mr. Brewer,
On August 10, 2018, Kelli Park of this office met with Josh Cagle to perform a
Compliance Evaluation Inspection on the Roaring River Chalets wastewater treatment
system. Mr. Cagle was filling in for the operator in responsible charge (ORC); Paul
Isenhour. 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 Environmental Protection
Agency inspection form notes the areas that were evaluated for this inspection. The
findings and observations are outlined below: .
I. Permit
The NPDES permit became effective August 1, 2016, and expires on March 31, 2021.
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 in compliance with all permit limits. -
Grab samples are taken from an access point in the effluent pipe as it leaves the plant
and before it reaches the receiving stream.

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 instantaneous flow is measured by collecting effluent in a bucket for a minute of time.
The effluent depth in the bucket is then measured, and the flow rate is manually calculated.
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.
VI. Facility Site Review
All components of the 0.005 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 dissolved oxygen is
maintained around 2 milligrams per liter. The secondary clarifier looked clean and was
discharging clear effluent. Effluent is disinfected by chlorine tablets, and then
dechlorination tablets are used before the effluent leaves the plant.
There is not a clear path to where the effluent pipe discharges into the receiving stream.
There is rip rap along the side of the stream that the operators walk down. It is suggested
that a clearer, safer, path is made so that there is easy access to the end of the pipe. We
suggest clearing a small section of the rip rap and putting in steps.
VII. Effluent/Receiving Waters 1
The effluent from the facility was clear the day of inspection. Effluent was being
discharged into the Middle Fork offthe South Fork of the New River which is classified as
a water supply, highly developed, rout stream in the New River watershed.
VIII. Sludge Maintenance and Handling
d e was reported to be um e� about once a year due to low flow in the plant. Triple
Slug p P P
T Plumbing pumps the sludge and ,the time, date, and how much was pumped is recorded
into the operator log on site. It is a so 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,
