Mr. Smith,

Environmental Quality
May 3, 2024
On May 3, 2024, Jim Westcott from the Raleigh Regional Office visited your Single-family
residence wastewater treatment and spray irrigation system to evaluate compliance with the
subject permit. The assistance of Mr. Smith during the inspection was appreciated.
The facility is permitted for the operation 480 gallon per day (GPD) wastewater treatment and
irrigation facility consisting of a 1,000 gallon baffled septic tank with an effluent filter; a 1,000
gallon sand filter pump tank with 1/3 horsepower (hp) pump; dual 72 square foot (ft2) covered
surface sand filters with free access covers; a tablet chlorinator; a 3,000-gallon storage/pump
tank with a 1.5 hp submersible irrigation pump; a 0.26-acre spray irrigation area and all
associated piping, valves, controls, and appurtenances with no discharge of wastes to surface
waters.
The permit, which was issued May 19, 2017, is effective through March 30, 2022. Division
records indicate the required annual fee for the period ending October 31, 2024, due November
3, 2023, has been paid.
Findings during the inspection were as follows:
1. Treatment system Operation: The wastewater treatment system shall be effectively
maintained and always operated so there is no discharge to surface waters, nor any
contravention of groundwater or surface water standards. The treatment system
components are to be inspected weekly and monthly by the permittee.
At the time of inspection, the permittee was on -site and provided a comprehensive tour
of the facility. The system components were tested and evaluated at the time of
inspection.

2. Pumping the septic tank: You are required to inspect the septic tank annually 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. The non -discharge
permit requires the permittee to retain records associated with residuals disposal for a period
of 5 years. The permittee provided a receipt from Septic Blue Services dated 2/28/2023
of the residuals removed from the system. The effluent filter is cleaned by the permittee
each month.
3. Disinfection: The system uses a tablet chlorination disinfection unit for disinfection of
wastewater. The chlorination tablet disinfection system provides effective disinfection and
reduces harmful bacteria from entering the environment. The chlorine tablet disinfection
system should be checked weekly to ensure proper disinfection of the wastewater prior to spray
irrigation. The tablet chlorinator was located at the time of inspection. The tablet feeder
had the correct tablets in the chlorinator and adequate supply on site. The control
junction box with visual/audible alarm was located.
4. Proper Operation and Maintenance: The system shall be inspected monthly to make
certain of the proper operation of the spray and irrigation system and that the Sol is
assimilating the disposed treated wastewater with no surface runoff, and that no objectionable
odors are being generated. Any visible signs of a malfunctioning system shall be documented,
and steps taken to correct the problem. At the time of inspection, the spray irrigation
system was evaluated for operation. The spray field vegetative cover was in good
condition, there was no evidence of surface runoff or ponding. The perimeter fencing
was secured.
Please continue to periodically inspect and evaluate the wastewater spray irrigation system
components are properly maintained and operating as designed. Maintain all associated
operational records onsite for a period of fives as required by the subject permit.
If you have questions or comments about this inspection or the requirements to take corrective
action (if applicable), then please contact Jim Westcott at james.westcottC&ncdenr. og_v or 919-
