Subject: Compliance Evaluation Inspection
Single Family Rsidences—General Pemrit NCG550000
Single Faimly Residence - 6915 Innesbrook Way
Certificate of Coverage NCG550596
Durham County
Dear Mr. Guidry:
On October 17, 2024, Danny Smith from the Raleigh Regional Office of the Division of Water
Resources (DWR) visited your single-family residence (SFR)wastewater treatment system to
evaluate compliance with the subject General NPDES Permit.
This wastewater treatment system is located at 6915 Innesbrook Way in Durham County and is
currently permitted to Charles Guidry. Our records indicate the wastewater treatment system
consists of a septic tank, sub-surface sandfilter, tablet chlorinator, tablet de-chlorinator and
effluent discharge pipe.
General NPDES Permit NCG550000 and Certificate of Coverage (COC)NCG550596 authorize
this discharge of domestic wastewater from your treatment system to receiving waters designated
as unnamed tributary to Little River in the Neuse River Basin. This authorized discharge is in
accordance with the effluent limits and monitoring requirements established within the General
Permit.
The subject site visit and file review revealed the following:
1. Pumping the septic tank: Septic tanks should be pumped out approximately
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.
For your reference, the General NPDES Permit requires the permittee to retain records
associated with sewage disposal activities for a period of at least S years.

2. Chlorine tablets in the chlorinator: You are reminded that it is requirement for chlorine
tablets to be maintained in the chlorinator to ensure proper disinfection of the discharged
wastewater. Chlorine tablets are intended to 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.
Please continue to ensure the correct type of tablets are used and maintained in the
chlorinator and de-chlorination contact tubes as required by the General NPDES Permit.
Please be sure to keep records of this nature available for your reference and use during
future inspections. (Note: Examples of these products (disinfection and the disinfection
neutralizer) can be readily observed online. You may wish to conduct an online search by
using google for "chlorine tablets for wastewater"and "dechlorination tablets for
wastewater")
3. Discharge outlet location. The permittee is required to conduct a visual review of the
outfall location at least twice each year(once 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.
Mr. Guidry had recently/actively been maintaining the outfall to ensure it was assessable
and flow was unobstructed. The outlet location was free from vegetation/overgrowth and
was assessable at the time of the inspection.
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 (wastewater discharge) leaving the treatment system. This sampling effort is
required to be conducted annually.
If you have not already collected the effluent for this year,please collect a representative
sample of the effluent and have it analyzed by a certified commercial laboratory. If no
wastewater flow is observed from your system,please document that information for your
records and use during the next system inspection.
