Subject: Compliance Evaluation Inspection
Single Family Residence - 6906 Innesbrook Way
General Wastewater Permit—NCG550000
Certificate of Coverage NCG550592
Durham County
Dear Ms. Pickett:
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 6906 Innesbrook Way in Durham County and is
currently permitted to Joyce Pickett. Our records indicate the wastewater treatment system
consists of a septic tank, sub-surface sandfilter, tablet chlorinator, and effluent discharge pipe.
General NPDES Permit NCG550000 and Certificate of Coverage (COC)NCG550592 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 5 years.
2. 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 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 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.
The outlet location was free from vegetation/overgrowth and was assessable.
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.

5. 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

compliance monitoring fee has been paid through 1013112025. There are no overdue
fees.
Thank you for your attention to these matters. Please continue to periodically inspect the
wastewater treatment system ensuring the treatment components are always maintained and in
good operating order. You are also reminded to maintain all monitoring data and associated
maintenance records. These materials should be maintained for a minimum of five years and be
available for review.
