Section D: Summary of Finding/Comments (Attach additional sheets of narrative and checklists as necessary)
Findings during the inspection were as follows:
1. Treatment system Operation: The wastewater treatment system shall be always
maintained to prevent seepage of sewage to the surface of the ground. The system was
operating as designed 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. A pumping
company can check the status periodically and determine when pumping is required.
During the inspection, the permittee provided verification that the septic tank was
pumped out on April 26, 2023. 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 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, always including ...disinfection units...
and in good operating order. The correct chlorine tablets in the chlorinator at the time of
inspection. Please continue to ensure the correct type of tablets are used and maintained in the
chlorinator as required by the General NPDES Permit.
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. At the time of inspection, a receipt of the required annual effluent
analysis was not provided. 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 1, 2023 and submit the results to this office within 3 weeks after sampling results are
received. 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.
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 clear of obstruction and well maintained on the day of the inspection.
Please ensure the outlet is always visible/maintained and cleared of vegetation, soil, and leaves.
