Subject: Compliance Evaluation Inspection
Single Family Wastewater Treatment System
General NPDES Permit NCG550000
Certificate of Coverage NCG550135
Facility: 1534 Mayapple Lane
Orange County
Dear Richard Wiersma:
On March 25, 2024, Jane Bernard 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 greatly appreciated.
Our records indicate the treatment system consists of a septic tank, sub -surface sand filter, tablet chlorinator
with chlorine contact chamber, discharge pipe and a rip -rap apron for post aeration.
General NPDES Permit NCG550000 and Certificate of Coverage (COC) NCG550135 authorize the discharge
of domestic wastewater from your treatment system to receiving waters designated as Eno River (classified
WS-V; NSW) 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.
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. During the inspection, Richard Wiersma
provided documentation showing McFarland Septic, LLC, pumped out the septic tank on
February 17, 2022. 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

4. 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.
5. 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. The
Effluent was sampled by McFarland Septic, LLC in 2023. All parameters were within permit
limits.
6. 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 visibleImaintained 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.
If you have questions or comments about this inspection or the requirements to take corrective action (if
applicable), then please contact Jane Bernard at 919-791-4233.
