Davie County •
Dear Ms. Warner:
• .5
As you may recall, on August 24, 2017 Patrick Mitchell of this office performed a compliance
inspection on the wastewater discharge system serving your property located at 179 Creekwood
Drive. The majority of the inspection reflects compliance. However, the following items require
your attention:
1. The subject residence is served by a hybrid wastewater treatment and disposal system. The
septic tank serving the system is connected to a bull run valve which allows wastewater to
be directed to either the discharging system or a subsurface disposal system.
It was indicated that the subsurface disposal system is the primary system in use, and the
discharging system can be utilized to allow subsurface recovery time or as needed by turning
the bull run valve. However, it was unclear at the time of inspection what percentage if any
of the wastewater is entering the discharging system. Please verify which system
(subsurface or discharge) the bull run valve is currently feeding. If any portion of the
wastewater flow is entering the discharging system, all permit condition requirements
shall be followed.
2. What is believed to be the effluent discharge outlet was identified (see enclosed site map
for the approximate location). There was no discharge initially observed. However, when
the system was charged with freshwater entering at the chlorinator, a discharge was
observed at the outlet (see enclosed photos). As a reminder, if the discharging system is
used at any time during a calendar year, an annual effluent sample is required as
described in Part I,Section A of your permit. The sample results must be maintained and
made available for future inspections.
3. There were no chlorine tablets present in the chlorinator at the time of inspection. If it is
determined that any wastewater is directed through the discharging system, proper
wastewater grade chlorine tablets must be used to ensure proper disinfection. Please
purchase wastewater chlorine tablets (e.g. calcium hypochlorite),-and have available
for use when utilizing the discharging system.

Section D:Summary of Finding/Comments(Attach additional sheets of narrative and checklists as necessary)
On August 24, 2017 Winston-Salem Regional Office(WSRO) staff conducted an announced routine
compliance inspection of the subject facility.Accompanying staff on the inspection was Ms. Elizabeth
Warner(Permittee&Owner)and Mr. Brian Warner(Resides in subject SFR).The following items
should be noted from the inspection:
-The system has a bull run valve following the septic tank. The valve outlets are attached to the sand
filter and to a pump tank.According to the diagram obtained during the inspection,the pump tank feeds
a subsurface disposal system.
-The owner indicated the subsurface system is the primary system and the discharging system is a
"backup"which is currently not in use.The discharge outlet was located. No discharge was initially
observed. However,when the system was charged with freshwater from a garden hose, via the
chlorinator,the discharge was observed to be dark with a septic odor. Requested the owner to ensure
the bull run valve is functioning properly and is diverting wastewater to the subsurface system. Offered
to dye the system if the homeowner desires. Owner to contact WSRO to request assistance if
necessary.
- No chlorine tablets were available and none observed in the chlorinator. Reminded owner that proper
wastewater chlorine tablets are required if any wastewater is flowing through the discharging system.
- No effluent sample results were available at time of inspection. Reminded owner that once per year
effluent must be sampled for the parameters required in the permit.A copy of the permit was left with
the owner for record.
OTHER NOTES:
-Owner had septic tank pumping receipts. Last pumped February 2017.
-Owner had a system file with a sketch of the system.
-Owner had issues with the pump tank controls on the subsurface system, resulting in backup in the
residence.This was repaired and reported as working at time of inspection.
*A follow-up compliance inspection may be necessary to determine if wastewater is entering the
discharging system, and if permit conditions are being followed.
