Certificate of Coverage NCG550713
Facility: 5709 Tomahawk Trail
Durham County

Dear Curtis Beatty, Jr.,

On August 17, 2021, Chris Smith from the Raleigh Regional Office visited your single-family
residence (SFR) wastewater treatment system to evaluate compliance with the subject General
NPDES Permit.

Our records indicate the treatment system consists of a septic tank, sub-surface sand filter, tablet
chlorinator with chlorine contact chamber, discharge pipe, and a rip-rap apron for post aeration.

General NPDES Permit NCG550000 and Certificate of Coverage (COC) NCG550713 authorize
the discharge of domestic wastewater from your treatment system to receiving waters designated
as an unnamed tributary to Cabin Branch in subbasin 03-04-01 [classified Water Supply (WS-
IV), Nutrient Sensitive Water (NSW)] in the Neuse River Basin. The authorized discharge is in
accordance with the effluent limits and monitoring requirements established within the General
Permit. The checked boxes below show what conditions were noted at your facility:

NCG550000 Ownership Change Form: According to Durham County deed of
records Curtis Beatty, Jr. owns the residence and property located at 5709 Tomahawk
Trail 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. To prevent further action, please submit a NCG550000
Ownership Change Form (attached) within fifteen (15) days of receipt of this letter. If
you have documentation proving that this record is in error, please forward it to our
office.

Treatment system operation: The wastewater treatment system shall be maintained
at all times to prevent seepage of sewage to the surface of the ground.

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.

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.

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. During
a phone call after the inspection, you informed the inspector that the effluent has not been
monitored within the last 12 months. 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 October 7, 2021. In the last inspection letter dated January 26,
2021 you were requested to sample your effluent and to submit the analytical results to
this office. The Raleigh Regional Office has not received the requested results. Failure

to monitor the effluent discharge as required is a violation of NPDES General Permit
NCG550000.

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.

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.

Within 15-days receipt of this letter, please submit a written response to this office indicating
the actions you will take or have taken to comply with or resolve the issues noted above.

If you have questions or comments about this inspection or the requirements to take corrective
action (if applicable), then please contact Chris Smith at 919-791-4257 or Vanessa Manuel at
919-791-4255.

Sincerely,
