Dear Spicer:
A Compliance Evaluation Inspection was performed by Division of Water Resources, Winston
Salem Regional Office, staff person Justin Henderson, on December 19, 2018. Mr. Tommy
Spicer, Operator in Responsible Charge (ORC), was present for this inspection. This type of
inspection consists of two basic parts: an in-office review of the facility files and self-monitoring
data and an on-site inspection of the facility While this inspection mostly reflects compliance
with Permit No. NC0076066, the following concerns requires your attention and action:
1) Significant holes were observed in two laterals in separate sand filters, resulting in
uneven distribution and ponding of effluent upon system dosing. Several remaining
laterals appeared to be unlevel containing high and low spots, which also was
contributing to uneven distribution and ponding of effluent. Observation of system dosing
should immediately be incorporated in the routine maintenance procedures and
performed at a frequency that will allow prevention of unevenly distribution and/or
ponding of effluent, as well as timely repair of damaged laterals within the sand filters.
2) There were no de-chlorination tablets present in the de-chlorination equipment at the
time of this inspection. Failure to properly maintain the dechlorination equipment and to
adequately replace tablets may result in effluent parameter violations. It is recommended
that weekly monitoring of dechlorination equipment be included in routine maintenance
procedures with monitoring frequencies increasing before and after high rainfall events
or high-water usage events.
3) Rust and corrosion was observed inside the effluent pump station control panel,
indicating that the pump station control panel no longer appeared to be weather-proof.
While, the control panel appeared to be operational at the time of this inspection, it is
strongly recommended that this panel be repaired or replaced with a weather-proof
panel box to ensure the integrity and reliably of the internal components, and to prevent
potential interruption of operations.

4) Post-calibration records for portable meters were unavailable for review at time of this
inspection. Post-calibration of portable meters, utilized for effluent parameter analyses,
must be performed and documented, and records made available upon request. All
calibration records must be maintained for a period of at least 3 years per Permit
Condition Part II. Section D. (6.).
