Compliance Evaluation Inspection
Single Family Wastewater Treatment System
NPDES General Permit NCG550000
Certificate of Coverage NCG550984
Facility Name: 740 Jeremiah Drive
Chatham County
Dear Mr. Murray:
On March 30, 2022, Cheng Zhang from the Raleigh Regional Office visited your single-family
residence (SFR) wastewater treatment system to evaluate compliance with the subject General NPDES
Permit. Your assistance during the pre -inspection email communication was appreciated.
Our records indicate the treatment system consists of a septic tank, one -pass sand filter, chlorinator, and
discharge pipe.
General NPDES Permit NCG550000 and Certificate of Coverage (COC) NCG550984 authorize the
discharge of domestic wastewater from your treatment system to receiving waters designated as
Overcup Creek (classified WS-IV, NSW, and CA waters) 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. The system was discharging at the
time of inspection. No solids were observed around the discharge point.
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. You stated that the septic tank was last
pumped on December 17, 2021. 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 duct 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
and you stated that you ran out of supply of chlorine tablets two months prior to the
inspection. Please ensure the correct type of tablets are used and maintained in the
chlorinator as required by the General NPDES Permit when the treatment system resumes
operation.
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 and
Total Residual Chlorine. Additional parameters (Total Nitrogen, Total Phosphorous, and
Ammonia Nitrogen) were added to the current NPDES General Permit NCG550000, which
became effective November 1, 2020 for Freshwater Discharges to High Quality Waters (HQW)
and Nutrient Sensitive Waters (NSW) (including Water Supply Waters (WS-II, WS-III, WS-IV,
and WS-V). You informed the inspector that the effluent has not been monitored within the
last 12 months. 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 October 8,
2022.
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.
6. 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, 2022, and due October 2, 2021, 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.
