On November 30, 2017, Paul DiMatteo and Jenny Graznak of the Division of Water Resources
("Division"), Winston-Salem Regional Office conducted a Compliance Evaluation Inspection of the above
referenced wastewater treatment system. Matthew Smith, Operator in Responsible Charge (ORC), was
present for the inspection. This type of inspection consists of two basic parts: an on-site inspection of the
facility and a review of facility files and self-monitoring data. An inspection summary follows and an inspection
report is attached for your records.
Site Review
1. Permit
The current permit became effective on July 1, 2016 and expires on May 31, 2021. A copy of the
current permit was available for review. Permitted components include a septic tank, sand filter,
and ultraviolet disinfection.
2. Facility Site Review
The facility was as described in the permit. The sand filter is dosed by a siphon mechanism; no
alarms are present. Although the facility is not located near the main school building or any other
surrounding buildings, access to the sand bed is not restricted to the general public.
3. Operation and Maintenance
The operator or a properly designated backup visits the site as required. Visitation logs were
current and available during the inspection. Mr. Smith said that school maintenance staff turned off
the UV alarm because it kept going off after hours. However, lights on the control panel indicated
that all bulbs were operational and the ORC said the bulbs are cleaned regularly. In case of a failure
of the UV system, Mr. Smith said he could add chlorine tablets to the old chlorine contact chamber.

4. Flow Measurement 1
Flow is estimated using data from the potable water meter. Given the low permitted discharge rate
of 3,000 gpd monthly average, care should be taken to ensure that the reported value is within
10% of the "true" value.
5. Effluent/Receiving Waters
The effluent is discharged into Cane Creek in the Cape Fear River Basin. Mr. Smith said that the
outfall was recently located but he himself did not know the exact location. An effluent sample
drawn from a valve after UV disinfection appeared clear.
Documentation Review
6. Records/Reports
Discharge Monitoring Reports (DMRs) and lab data are maintained according to the permit. DMRs
include all permit parameters. Copies of DMRs, operator visitation logs, lab reports and Chain -of -
Custody forms were available for review during the inspection.
7. Self -Monitoring Program
A review of DMRs from April, 2015 through September, 2017 showed the following violations,
which have been addressed through previous correspondence from this office:
A comparison of submitted DMR data and field records showed no errors or concerns.
8. Laboratory
All parameters are analyzed by Research & Analytical Laboratories, Certification #34. ORC measures
pH and temperature at the facility. All other samples are collected from a valve following
disinfection.
Temperature is measured using the digital thermometer on the Dissolved Oxygen meter. The
thermometer was last calibrated on October 12, 2017. pH meter pre -run calibration and sampling
procedures appeared acceptable.
9. Sludge Handling Disposal
Mr. Smith said that sludge is removed from the septic tank as needed. Records showed that sludge
was last removed by Jenkins Waste Management on 2/20, 4/28, 8/10 and 11/20 of this year.

Comment: Flow is estimated using the school's water meter. Beqinninq this school year flow has been
reported on the DMR to the nearest 1000 gallons (previously reported to the nearest 100
gallons). Note that the reported flow measurement should be within 10% of the true value
Since the flow limit at this facility is 3000 god with a typical reported flow around 2000 gpd,
this gives an acceptable range of —+/- 200 gpd, which is to small to be resolved if flow is
rounded to the nearest 1000 gallons.
