Subject: Compliance Evaluation Inspection
Single Family Wastewater Treatment System
General NPDES Permit NCG550000
Certificate of Coverage NCG550642
Facility: 343 Carlton Drive
Orange County
Dear Mr. Barrett,
On February 28, 2024, Donald Smith and Danny Smith 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 Wynne provided 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 NPDES Permit NCG550000 and Certificate of Coverage (COC)NCG550642 authorize
the discharge of domestic wastewater from your treatment system to receiving waters designated
as Wilson Creek(classified as Water Supply(WS-IV); Nutrient Sensitive Waters (NSW)) in the
Cape Fear River Basin. The authorized discharge is in accordance with the effluent limits and
monitoring requirements established within the General Permit. The items below show what
conditions were noted at your facility:
Findings during the inspection were as follows:
1. Treatment system operation: The wastewater treatment system shall be
maintained at all times to prevent seepage of sewage to the surface of the ground.
Prior to the inspection, you provided pictures and notice of some soil settlement
around the septic tank that was installed by a previous homeowner(Photo 1.).
Please fill in the holes and voids associated with the settlement. Please monitor
your septic tank closely for any irregular settlement or failure of the septic tank.
If tank settlement or other problems occur that affect the proper operation or
failure of your system, you are required to notify the Raleigh Regional Office as
required in NCG550000, Part II (D.)(3)—Anticipated Noncompliance.

2. 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. You provided
documentation showing Septic-R-Us, LLC pumped out the septic tank on
February 2, 2024. The General NPDES Permit requires the permittee to retain
records associated with sewage disposal activities for a period of at least 5 years.
3. 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. 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 observed 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. With weekly inspections, ensure the
tablets feed to the bottom of the chlorinator tubes. Chlorine tablets can swell
and get stuck in the tube where they do not settle and come in contact with the
wastewater stream.A straight rod can be used to help push the chlorine tablets
down when needed.
4. 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 Flow, BOD
(Biochemical Oxygen Demand), Total Suspended Solids, Fecal Coliform, Total
Residual Chlorine, Total Nitrogen, Ammonia Nitrogen and Total Phosphorous.
Within 30-days of receiving this letter, 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 lab results if you have. If you have not monitored your
effluent, then please collect a representative sample of the effluent, have it
analyzed by a certified commercial laboratory and submit the results to this office
no later than April 30, 2024. 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. If conditions for sampling become favorable, then arrange
to collect a sample. Failure to monitor the effluent discharge as required is a
violation of NPDES General Permit NCG550000.

5. 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 visible/maintained and cleared of vegetation, soil, and leaves.
Part II Section B.14 of General Permit NCG550000 requires the permittee to "pay the annual
administering and compliance monitoring fee within thirty days after being billed by the
Division." Division records indicate the required annual fee ($60 per year) for the period ending
September 30, 2024, and due November 3, 2023, has been paid. There are no overdue fees for
the subject COC.
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 and associated maintenance records onsite for a minimum of
three years and available for inspection.
Please submit a written response to this office by April 30, 2024 indicating the actions you will
take or have taken to comply with or resolve the issue noted in item 4 above.
If you have questions or comments about this inspection or the requirements to take corrective
action(if applicable), then please contact Donald Smith at 919-791-4234
