Dear Mrs. Grunert
On December 20, 2023, Curtis Tyree 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; 2 above ground sand filters;
UV disinfection; and an effluent discharge pipe.
General NPDES Permit NCG550000 and Certificate of Coverage (COC) NCG550883 authorize
the discharge of domestic wastewater from your treatment system to an unnamed tributary to
Church Brange Creek and into the Cape Fear River Basin2
Findings during the inspection were as follows:
I. The septic tank shall be checked annually and pumped out every 3 to S years. The septic
tank was pumped out in June 2021 by McFarland Septic Service.
2. Treatment system operation. The treatment system shall be maintained at all times to
prevent seepage of sewage to the surface of the ground. At the time of the inspection, the
system appeared to be well maintained.
3. Outfall location. A visual review of the outfall location shall be executed 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. At the time of the inspection, the
outfall location was clear and appeared to be well maintained and free of any obstructions.
There was no water discharging at the time of the inspection.
