Compliance Evaluation Inspection
Single Family Wastewater Treatment System
NPDES General Permit NCG550000
Certificate of Coverage NCG551332
Facility Name: 2 Pine Tree Lane
Orange County
Dear Mr. Fisher:
On December 15, 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 post -inspection phone conversation was appreciated.
Our records indicate the treatment system consists of a septic tank, primary sand filter, secondary
sand filter, chlorinator, chlorine contact chamber, effluent pump tank, and effluent pipe.
General NPDES Permit NCG550000 and Certificate of Coverage (COC) NCG551332 (expired on July
31, 2018) authorize the discharge of domestic wastewater from your treatment system to receiving
waters designated as an unnamed tributary to New Hope Creek (classified WS-V, NSW 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 not 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. The property manager stated that the septic
tank was lastpumped in September 2022. The General NPDES Permit requires the permittee to

retain records associated with sewage disposal activities for a period of at least 5 years. Please
have the septic tank checked1pumped as soon aspossible.
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 pennittee 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 pennittee 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 had a supply of correct chlorine tablets. Please ensure
the correct type of tablets are used and maintained in the chlorinator as required by the
General APDES 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. You informed the inspector that the effluent had 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 June 30, 2023.
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 visiblelmaintained and cleared of vegetation, soil and leaves.
6. Part 11 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 fees have been paid.
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 onsitefor a minimum of three years and
availablefor inspection.
