Subject: Compliance Evaluation Inspection
Single Family Wastewater Treatment System
General NPDES Permit NCG550000
Certificate of Coverage NCG551449
Facility: 120 Debra Drive
Durham County

Dear Mr. Harvey:

On January 18, 2022, Stephanie Goss and Cassidy Kurtz from the Raleigh Regional Office
visited your single-family residence (SFR) wastewater treatment system to evaluate compliance
with the subject General NPDES Permit. You were contacted to schedule an inspection via a
mailed letter with no response. The dog sitter/house sitter was home at the time of the inspection
and allowed the inspectors access to the fenced-in back yard. The inspector left a packet of
information with the dog sitter/house sitter regarding Single Family Treatment Systems and the
requirements of the General Permit at the residence.

Our records indicate the treatment system consists of a septic tank, sub-surface sand filter, tablet
chlorinator with chlorine contact chamber, dechlorination chamber and discharge pipe.

General NPDES Permit NCG550000 and Certificate of Coverage (COC) NCG551449 authorize
the discharge of domestic wastewater from your treatment system to receiving waters designated
as an unnamed tributary to Panther Creek classified a WS-IV, Nutrient Sensitive Waters (NSW)
in the Neuse 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. Within 30-days of
receiving this letter, please send a copy of the most recent receipt/invoice to this office
showing the date the septic tank was last checked and/or pumped out. 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,
including...disinfection units...at all times and in good operating order. The inspector was not
able to open the chlorinator to determine if there were any chlorine tablets in the chlorinator.
Please ensure the correct type of tablets are used and maintained in the chlorinator as
required by the General NPDES Permit.

4. 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 not able to open the dechlorinator to determine if
there were any dechlorination tablets in the treatment unit. Please ensure the correct type of
tablets are used and maintained in the dechlorinator 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. Within
30-days of receiving this letter, please let this office know if you have monitored your
effluent discharge within the last 12 months and provide this office with a copy of the lab
results if you have. 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 April 30, 2022. 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.

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 not visible and accessible the day of the inspection. Please ensure the
outlet is always visible/maintained and cleared of vegetation, soil and leaves.

The wastewater treatment system should be periodically inspected 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 via email at [e-mail] or 919-791-
