NPDES Permit # NCO046418
Wilkes County
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. N00046418, the following concerns requires your attention and action:
1) Proper maintenance of the surface sands filters must be performed at a frequency that
will prevent ponding of effluent and/or vegetative growth. Weekly raking is highly
recommended to comply with Permit Condition Part II Section C. (2.) which requires the
Permittee to properly operate and maintain all facilities and systems of treatment and
control at all times.
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 de -chlorination equipment be included in routine maintenance
procedures with monitoring frequencies increasing before and after high rainfall events
or high-water usage events.
3) Post -calibration records for portable meters were unavailable for review at time to 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 IL Section D. (6.).
