On June 19, 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 269 Screech Owl Road, in Chatham County NC
and is currently permitted to Christopher Senior.
General NPDES Permit NCG550000 and Certificate of Coverage (COC)NCG550326 authorize
this discharge of domestic wastewater from your treatment system to receiving waters designated
as unnamed tributary to Rocky River in the Cape Fear 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.
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 required that chlorine
tablets be maintained in the chlorinator to ensure proper disinfection of the discharged

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

this nature available for your reference and used during future inspections.
3. Discharge outlet location. The permittee is required to conduct a visual review of the

the problem.
To comply with the general permit monitoring requirements,you need to be able to
sample and analyze the effluent. Please continue to take the necessary steps to ensure the
