Subject: Compliance Evaluation Inspection
Single Family Wastewater Treatment System
General NPDES Permit NCG550000
Certificate of Coverage NCG551645
Durham County
Dear Mr. Matney:
On September 10, 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. The assistance provided by you and your wife during the inspection was greatly appreciated.
Our records indicate the treatment system consists of a septic tank, sub -surface sand filter, disinfection
consisting of tablet chlorinator with chlorine contact chamber and tablet dechlorinator, effluent piping and
outfall discharge with aeration/erosion-controlled rip -rap.
General NPDES Permit NCG550000 and Certificate of Coverage (COC) NCG55I645 authorize the
discharge of domestic wastewater from your treatment system to receiving waters designated as an
unnamed tributary to the Little River (classified WS-I1; HQW; NSW; CA) 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:
N Treatment system operation: The wastewater treatment system shall be maintained at all
times to prevent seepage of sewage to the surface of the ground.
N Pumping the septic tank: You are required to inspect the septic tank at Ieast 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 stated the
septic tank was serviced by Scotty's Septic System within the last 2 years. Please continue to
monitor your septic tank as required by the permit.
N 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 far these tablets must indicate the tablets are atwroved
or wastewater use and not Lor sivinuning 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. The inspector did observe chlorine tablets in the chlorinator. Please
continue to ensure the correct type of tablets are used and maintained in the chlorinator as
required by the General NPDES Permit.
® Dechlorination tablets: You are responsible for always having dechlorination tablets (if a
required part of your system) in place. They must be the kind for wastewater treatment and not for
swimming pools. The inspector did observe dechlorination tablets in the treatment unit. Please
continue to ensure the correct type of tablets are used and maintained in the dechlorinator as
required by the General NPDES Permit.
® Analyzing the effluent: Part 1. C., 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 Plow, BOD (Biochemical Oxygen Demand), Total Suspended Solids, Fecal Coliform and
Total Residual Chlorine. Within 30-days of receiving this letter, 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 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. The discharge
pipe was visible and accessible the day of the inspection. Please continue to ensure the outlet is
always maintained and cleared of vegetation, soil and leaves.
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.
If you have questions or comments about this inspection or the requirements to take corrective action (if
applicable), then please contact Vanessa Manuel at 919-791-4255.
