Section D: Summary of Finding/Comments (Attach additional sheets of narrative and checklists as necessary)
Findings during the inspection were as follows:
1. 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, Mr. Gillespie provided documentation
showing that John E. Byrd Trucking and Tractor Service pumped out the septic tank on July 14, 2023.
The General NPDES Permit requires the permittee to retain records associated with sewage disposal
activities for a period of at least 5 years.
2. 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 a dozen chlorine tablets in the chlorinator. We recommend no more
than 1-2 tablets be placed in the system as needed. The placement of a large number of tablets can
result in them becoming stuck in the pipe, and limiting contact of the tablets with the effluent water.
Please ensure the correct type of tablets are used and maintained in the chlorinator as required by
the General NPDES Permit.
3. 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 During the inspection, you
informed the inspector that the effluent has not been monitored within the last 12 months. In the last
inspection letter dated March 21, 2018, you were requested to sample your effluent and to submit the
analytical results to this office. The Raleigh Regional Office has not received the requested results.
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
October 24, 2023. 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 and 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.
4. 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; although no discharge was noted. Please continue to ensure
the outlet is 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,
2023 and due October 2, 2022, 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.
