Subject: Compliance Evaluation Inspection
Single Family Wastewater Treatment System
NPDES General Permit NCG550000
Certificate of Coverage NCG550598
Facility Name: 6919 Innesbrook Way
Durham County
Dear Mr. Sanders:
On March 28, 2024, 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 inspection was appreciated.
Our records indicate the treatment system consists of a septic tank, sand filter, and effluent pump
tank.
General NPDES Permit NCG550000 and Certificate of Coverage (COC) NCG550598 authorize the
discharge of domestic wastewater from your treatment system to receiving waters designated as an
unnamed tributary to Little River (classified WS-IV; NSW waters) in the Neuse 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 via a
temporary above ground pipe from the effluent pump tank to a roadside ditch at the time of
inspection.
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 in 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. Disinfection: Your system is lacking disinfection, either chlorine tablets or a UV light system.
New rules put into place on August 1, 2007 require all SFR systems to have a means of
disinfection (and dechlorination when chlorine tablets are used to disinfect, if the system was
installed since that date). The Division issued an Authorization to Construct for this permit to
install UV disinfection, control panel, and discharge point with Riprap on April 4, 2024. Once
installed, UV disinfection system provides effective disinfection and prevents/limits harmful
bacteria from discharging to the environment. Unless the UV disinfection unit is monitored
by telemetry, the unit shall be checked weekly. The lamp(s) and quartz sleeve(s) shall be
cleaned or replaced as needed to ensure proper disinfection of the discharged wastewater.
Please ensure the UV disinfection unit is properly operated and maintained to ensure optimal
performance.
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. 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 August 31, 2024.
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. At the time
of inspection, a temporary effluent pipe (above ground) was run from the effluent pump
tank to a roadside ditch. It is understood that an effluent discharge point with Riprap will
be installed together with UV disinfection system. Please 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 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 onsite for a minimum of three years and
available for inspection.
