Subject: Compliance Evaluation Inspection
Single Family Wastewater Treatment System
General NPDES Permit NCG550000
Certificate of Coverage NCG551413
Facility: 4225 Morton Drive
Durham County
Dear Ms. Frazier:
On May 31, 2022, Staff from the Raleigh Regional Office visited your single-family residence (SFR)
wastewater treatment system to evaluate compliance with the subject NPDES General Permit. Your
assistance during the inspection was greatly appreciated.
Our records indicate the treatment system consists of a septic tank, primary sand filter, secondary sand
filter, tablet chlorinator with chlorine contact chamber, tablet dechlorinator, discharge pipe, rip -rap
aeration and associated appurtenances.
General NPDES Permit NCG550000 and Certificate of Coverage (COC) NCG551413 authorize the
discharge of domestic wastewater from your treatment system to receiving waters designated as unnamed
tributary to the Eno River (classified WS-IV; NSW, CA) in the Neuse River Basin. The authorized
discharge is in accordance with the effluent limits and monitoring requirements established within the
General Permit. The items below show what conditions were noted at your facility:
Findings during the inspection were as follows:
1. NCG550000 Ownership Change Form: According to Durham County deed of records,
you own the residence and property located at 4225 Morton Drive in Durham, North
Carolina. As the property owner, you are also the owner of the existing single-family
wastewater treatment system, which treats the domestic wastewater from the residence and
releases the effluent to the receiving waters indicated above. Because the treatment system
makes an outlet to waters of the state, it is an activity for which the subject permit is
required. To comply with North Carolina General Statute § 143-215.1(a), which requires a
person to obtain a permit to make an outlet into the waters of the state, you will need to
complete and submit the attached NCG550000 Ownership Change Form to the Division.

If you have any questions regarding change in permit ownership or completing the
form, then please contact Cassidy Kurtz at 919-791-4237.
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 did not observe 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 did not observe 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 November 3.
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 NCGS50000.

Section D: Summary of Finding/Comments (Attach additional sheets of narrative and checklists as necessary)
On May 31, 2022, Staff from the Raleigh Regional Office visited your single-family residence (SFR)
wastewater treatment system to evaluate compliance with the subject NPDES General Permit. Your
assistance during the inspection was greatly appreciated.
Our records indicate the treatment system consists of a septic tank, primary sand filter, secondary
sand filter, tablet chlorinator with chlorine contact chamber, tablet dechlorinator, discharge pipe,
rip -rap aeration and associated appurtenances.
General NPDES Permit NCG550000 and Certificate of Coverage (COC) NCG551413 authorize the
discharge of domestic wastewater from your treatment system to receiving waters designated as
unnamed tributary to the Eno River (classified WS-IV; NSW, CA) in the Neuse River Basin. The
authorized discharge is in accordance with the effluent limits and monitoring requirements established
within the General Permit The items below show what conditions were noted at your facility:
Findings during the inspection were as follows:
1. NCG550000 Ownership Change Form: According to Durham County deed of records, you own

owner, you are also the owner of the existing single-family wastewater treatment system, which treats
the domestic wastewater from the residence and releases the effluent to the receiving waters
indicated above. Because the treatment system makes an outlet to waters of the state, it is an
activity for which the subject permit is required. To comply with North Carolina General Statute § 143-
215.1(a). which requires a person to obtain a permit to make an outlet into the waters of the state,
