Subject: Compliance Evaluation Inspection Permirting Section
Single Family Wastewater Treatment System
NPDES General Permit NCG550000
Certificate of Coverage NCG550019
Durham County
Dear Mr. Shanafelt:
On September 5, 2018, Vanessa Manuel from the Raleigh Regional Office visited your single-family residence
(SFR) wastewater treatment system to evaluate compliance with the subject NPDES General Permit. Your
assistance during the inspection was greatly appreciated.
Our records indicate the treatment system consists of a septic tank, sub-surface sand filter, tablet chlorinator
with chlorine contact chamber, and discharge pipe.
General Permit NCG550000 and Certificate of Coverage (COC)NCG550019 authorize the discharge of
domestic wastewater from your treatment system to receiving waters designated as an unnamed tributary to
Little River (classified WS-II; HQW;NSW) in the Neuse River Basin. The authorized discharge is in
accordance with the effluent limits and monitoring requirements established within the General Permit. The
checked boxes below show what conditions were noted at your facility:
NPDES Permit Name/Owner Change Form: According to Durham County deed of records, you
are the owner of the residence and property located at 1314 Oak Forest Drive in Hillsborough,North
Carolina. As the property owner, you are also the owner of the existing single-family wastewater
treatment system, which treats the domestic wastewater from the residence and releases the effluent to
the receiving waters indicated above. Because the treatment system makes an outlet to waters of the
state, it is an activity for which the subject permit is required. To comply with North Carolina General
Statute '§ 143-215.1(a),which requires a person to obtain a permit to make an outlet into the waters of
the state, you will need to complete and submit the attached NPDES Permit Name/Ownership Change
Form to the Division. If you have any questions regarding change in permit ownership or completing
the Permit Name/Ownership Change Form, then please contact Vanessa Manuel at 919-791-4255.

® Chlorine tablets in the chlorinator: You are reminded that it is required that chlorine tablets be
maintained in the chlorinator to ensure proper disinfection of the discharged wastewater. Chlorine
tablets provide effective disinfection and prevent/limit harmful bacteria from discharging to the
environment. The product label for these tablets must indicate the tablets are approved for wastewater
use and not for swimming pools. The inspector did not observe any chlorine tablets in the chlorinator.
Part 1,Permit Conditions (Operation &Maintenance), item 4 within General Permit NCG550000
requires the permittee to maintain all system components, including...disinfection units...at all times and
in good operating orde:Please erisure"the correct type of tablets-are used and maintained in the
chlorinator.
FITreatment system operation: The wastewater treatment system shall be maintained at all times to
prevent seepage of sewage to the surface of the ground.
FL Pumping the septic tank: You are required to inspect the septic tank at least yearly to determine if
solids must be removed or if other maintenance is necessary. Septic tanks should be pumped out every
five years or when the solids level is found to be more than 1/3 of the liquid depth in the septic tank
compartment, whichever is greater. A pumping company can check the status periodically and
determine when pumping is required. During the inspection, you informed the inspector the septic tank
was checked and/or pumped out 3 months ago. Within 45-days of receiving this letter,please let this
office the date the septic tank was last checked and/or pumped out.
Analyzii.g the effluent: Part 1. A., Effluent Limitations and Monitoring Requirements, within
General Permit NCG550000 requires a permittee to sample and analyze the effluent leaving his/her
treatment system prior to discharge annually. Parameters to be sampled and analyzed include Flow,
BOD (Biochemical Oxygen Demand), Total Suspended Solids, Fecal Coliform and Total Residual
Chlorine. If you have not monitored your effluent within the last 12 months,then please collect a
representative sample of the effluent if it is discharging,have it analyzed by a certified commercial
laboratory and submit the results to this office no later than November 309 2018. If, during this time,
you are unable to collect a representative sample of the effluent discharge due to insufficient flow from
the discharge pipe, then update this office with that information and continue to monitor the discharge
and if conditions for sampling become favorable,then arrange to collect a sample.
V Discharge outlet location. A visual review of the outfall location shall be executed twice each year
(one at the time of sampling)to ensure that no visible solids or other obvious evidence of system
malfunctioning is observed. Any visible signs of a malfunctioning system shall be documented and
steps taken to correct the problem. Please continue to ensure the outlet is always maintained and cleared
of vegetation, soil and leaves. The discharge pipe was visible and accessible the day of the inspection.
Please continue to periodically inspect the wastewater treatment system to ensure the treatment components are
always maintained and in good operating order. You are also reminded to maintain all monitoring data onsite
for a minimum of three years from date of sampling and available for inspection.
