SUBJECT: Compliance Evaluation Inspection

NPDES Permit No. NC0067016
Watauga County
Dear Mr. Clark
On July 10, 2018, Kelli Park and Gary Hudson, of this office, met with Eric Bolick,
ORC, to perform a Compliance Evaluation Inspection on the Parkway Elementary School
wastewater treatment system. 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. Permit
The NPDES permit became effective September 1, 2016, and expires March 31, 2021.
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 December 2017 showed that the facility was not in compliance with all permit
limits. All violations were for exceeding biological oxygen demand limits. Please see the
table below.

III. Flow Measurement
The flow is measured by the school water usage.
IV. Operations and Maintenance
The wastewater treatment plant appeared to be very well maintained and operated.
V. Facility Site Review
All components of the 0.005 million gallons per day facility appeared to be functioning
properly. The flow is distributed through the sand bed, which is evenly raked and has no
odor. Effluent is discharged into a chlorine contact tank before entering the stream. The
maintenance and operation of the facility is excellent.
VI. 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.
VII. Effluent/Receiving Waters
The effluent from the facility was clear the day of the inspection. Effluent was being
discharged into Laxon Creek, class C waters, in the New River Basin. There were no
solids, no color, and no odor associated with the effluent. The effluent is considered
excellent. Periodically there are cows in the area of the discharge as the plant is in a cow
pasture.
The compliance evaluation inspection is satisfactory. Mr. Bolick maintains and operates
the facility in an excellent 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].
