On June 22, 2017, Paul DiMatteo of the Division of Water Resources ("Division"), Winston-Salem Regional Office
conducted a Compliance Evaluation Inspection of the above referenced wastewater treatment system. Mike Carson,
Operator in Responsible Charge, was present for the inspection. An inspection summary follows and an inspection
report is attached for your records.
Site Review
1. Permit
The current permit became effective on April 1, 2017 and expires on May 31, 2021. Permitted components
include a recirculating surface sand filter and ultraviolet disinfection. A copy of the current permit was
available for review.
2. Facility Site Review
The facility is as described in the permit. After initial treatment, 1/3 of the effluent is returned to the head of
the plant, and the rest continues to disinfection and then to discharge. The UV system appears to be
working properly. Replacement bulbs as well as backup chlorine tablets are maintained on site.
3. Operation and Maintenance
The facility appeared to be generally well maintained. Mr. Carson reported that a resident in the community
performs general grounds maintenance including raking the sand bed weekly.
However, during the inspection the following concerns were noted:
a. Operation of the sand filter pump's high water alarm could not be demonstrated due to Mr.
Carson's injury and lack of familiarity with the controls. Please ensure the alarm is in proper working
order at all times.
b. Several concrete access lids to underground tanks were cracked, with one lid being covered by a
metal sheet. Please be wary of safety hazards when working around cracked or broken lids.

The effluent pipe is located at the bottom of the hill below the sand filter system. The receiving stream is
Travis Creek in the Cape Fear River Basin. The effluent appeared clear with no visible solids.
5. Flow Measurement
The permit requires weekly instantaneous flow measurement. Flow is estimated based on the community
well's water meter.
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 July, 2015 through March, 2017 showed only the following violation:

temperature. Mr. Carson's field parameter certification number is 5195. Calibration records for Mr. Carson's
meters are maintained with records and reports. Meritech, Inc. analyzes all other parameters for the facility:
Biochemical Oxygen Demand, Total Suspended Solids, Ammonia, Total Nitrogen, Total Phosphorus, and
Fecal Coliform.
Sludge Handling Disposal
Pee-Wee's Septic Tank Service removes sludge from the septic tanks approximately every 6 months. Records
of this service were available for review during the inspection. The last pump -offs occurred in January 2016,
August 2016 and January 2017.
