Single Family Wastewater Treatment System
General NPDES Permit NCG550000
Certificate of Coverage NCG551031
Durham County
Dear Ms. McAbee:
On September 12, 2019, Vanessa Manuel from the Raleigh Regional Office visited your single-family
residence (SFR) wastewater treatment system to evaluate compliance with the subject General NPDES
Permit. No one was at home at the time of the inspection. The inspector left a packet of information
regarding Single Family Treatment Systems and the requirements of the General Permit at the residence.
Division staff makes every effort to contact permittees prior to conducting site visits to give the permittee
an opportunity to be present during the inspection and to ensure the inspector will have access to the
treatment units. Please provide this office with a telephone uuttther and entail address that can be used
to contact you to schedule fittitre inspection site visits.
Our records indicate the treatment system consists of a septic tank, pump tank, distribution box, dual
primary sub -surface sand filters in parallel, secondary sub -surface sand filter, tablet chlorinator, chlorine
contact tank, and discharge pipe.
General NPDES Permit NCG550000 and Certificate of Coverage (COC) NCG551031 authorize the
discharge of domestic wastewater from your treatment system to receiving waters designated as an
unnamed tributary to Sevenmile Creek (classified WS-IV; 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:
® Treatment system operation: The wastewater treatment system shall be maintained at all
times to prevent seepage of sewage to the surface of the ground.
® 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 Ievel is found to be more than L 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. Within 30-days of receiving this
letter, please let this office know the date the septic tank was last checked and/or ptimped out.
® 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 swinznzine Pools. Part 1, Section D (1) of General NPDES Permit
NCG550000 requires the permittee to inspect the tablet chlorinator weekly to ensure there is an
adequate supply of tablets for continuous and proper operation. Section D (4) requires the
permittee to maintain all system components, including... disinfection units ... at all times and in
good operating order. Please ensure the correct nape of tablets are used and maintained in the
chlorinator as required by the General NPDES Permit.
® Analyzing the effluent: Part 1. C., Effluent Limitations and Alonitoring 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. 11 thin 30-(lays of receiviizg this !utter, please let this office know if you
have monitored your effluent discharge within the last 12 months, and provide this office with a
copy of the tab results if you have. If you have not monitored your effluent, then please collect a
ref2resenlative 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 December 20, 2019, 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.
® Discharge outlet location. The permittee is required to conduct a visual review of the outfall
location at least 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 ensure
the outlet is always maintained and cleared of vegetation, soil and leaves.
The wastewater treatment system should be periodically inspected 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.
If you have questions or comments about this inspection or the requirements to take corrective action (if
