Subject: Compliance Evaluation Inspection
Single Family Wastewater Treatment System
General NPDES Permit NCG550000
Certificate of Coverage NCG550681
Facility: 3534 Cheek Road
Durham County

Dear Mr. Andrews:

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. No one was at home at the time of the inspection and you were contacted
to schedule an inspection via a mailed letter. The inspector left a packet of information
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, and discharge pipe.

General NPDES Permit NCG550000 and Certificate of Coverage (COC) NCG551047 authorize the
discharge of domestic wastewater from your treatment system to receiving waters designated as an
unnamed tributary to Chunky Pipe 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
DocuSign Envelope ID: 61FB4BA1-96F5-46E5-A753-73D67EF8B1FB

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.

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, 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.

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 visible and accessible the
day of the inspection. Please continue to ensure the outlet is always visible/maintained and cleared
of vegetation, soil and leaves.

Division records indicate the required annual fee ($60 per year) for the period ending September 30,
2022, and due October 2, 2021, has been paid. There are no overdue fees for the subject COC.

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 919-791-4256.

Sincerely,

Vanessa E. Manuel Assistant Regional Supervisor
