Subject: Compliance Evaluation Inspection
Single Family Wastewater Treatment System
General NPDES Permit NCG550000
Certificate of Coverage NCG551472
Facility: 41 Pintail drive
Person County
Dear Mr. Greene:
On October 26, 2022, Stephanie Goss 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 via telephone on October 28, 2022 was greatly
appreciated.
Our records indicate the treatment system consists of a septic tank, sub-surface sand filter, tablet
chlorinator with chlorine contact chamber, dechlorinator, and discharge pipe.
General NPDES Permit NCG550000 and Certificate of Coverage (COC) NCG551472 authorize
the discharge of domestic wastewater from your treatment system to receiving waters designated
as an unnamed tributary to Hyco Lake classified as Water Supply V (WS-V), Class B waters in
the Roanoke River Basin. The authorized discharge is in accordance with the effluent limits and
monitoring requirements established within the General Permit. 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. By January 31, 2023,
please submit a written response indicating when the septic tank will be
checked/cleaned. It must be cleaned and/or pumped as needed.
3. The General NPDES Permit requires the permittee to retain records associated with sewage
disposal activities for a period of at least 5 years.

4. 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 was
unable to positively identify if tablets were in the chlorinator. You stated via telephone on
October 28th that you regularly add the correct type of chlorine tablets into 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. Dechlorination tablets: You are responsible for always having dechlorination tablets (if a
required part of your system) in place. They must be the kind for wastewater treatment and
not for swimming pools. The inspector was unable to positively identify if tablets were in the
dechlorinator. You stated via telephone on October 28th that you regularly add the correct
type of dechlorination tablets into the treatment unit. Please continue to ensure the correct
type of tablets are used and maintained in the dechlorinator as required by the General
NPDES Permit.
6. 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 and Total Phosphorus. 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 January 31, 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.
7. 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 ensure the outlet
is always 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.” There are no overdue fees for the subject COC.
