Subject: Compliance Evaluation Inspection
Single Family Wastewater Treatment System
NPDES General Permit NCG550000
Certificate of Coverage NCG551391
Facility Name: SFR 402 Sandlewood Drive
Durham County
Dear Mr. Taylor:
On August 25th, Joe Myers from the Raleigh Regional Office visited your single-family
residence (SFR) wastewater treatment system to evaluate compliance with the subject General
NPDES Permit. Your wife's assistance during the inspection was greatly appreciated.
Our records indicate the treatment system consists of a septic tank, sub -surface sand filter, tablet
chlorinator with chlorine contact chamber, tablet dechlorinator, discharge pipe and a rip -rap
apron for post aeration.
General NPDES Permit NCG550000 and Certificate of Coverage (COC) NCG551391 authorize
the discharge of domestic wastewater from your treatment system to receiving waters designated
an unnamed tributary to Cabin Branch 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. 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 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. 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. 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 December 15th, 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.
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." The annual fee ($60 per year) for the period 03/01 rr2020 through 02/28/2021 was due
by 03/06/2020. This fee has not been paid and is overdue. Payment in the amount of $60
must be remitted to the Division as indicated on the attached Annual Permit Fee Invoice.
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.
