Subject:
Compliance Evaluation Inspection
Permit # WQ0000132
Facility: 702 Avalon Road
Durham County
On December 14, 2023, 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. Moore at the time of the inspection was appreciated.
The facility is permitted for the operation a .00045 (MGD) wastewater treatment and irrigation
facility consisting of a .001 gallon septic tank; a subsurface sand filter; a chlorine disinfection unit;
a .0015-gallon pump/storage tank with dosing pump; a 0.35-acre spray irrigation area with eight
spray heads (shared with permit # WQ0040020) and all associated piping, valves, controls, and
appurtenances with no discharge of wastes to surface waters.
The permit, which was issued June 19, 2018, is effective through August 31, 2023. Division records
indicate the required annual fee for the period ending June 30, 2024, due July 01, 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 gave a comprehensive tour of the system components.
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.
A receipt of the volume of residuals removed from the facility was not available at the time of
inspection. Within 30 days of receipt of this letter, please forward a contract receipt showing
the volume of residuals removed from the facility. The permittee stated that the system has not
been active for a period of ten years and the property is vacant.
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 tablets in the
chlorinator. The supply of the correct tablets was verified at the time of inspection. The control
junction box was located, and new electric control GFCI for the dosing pump has been
contracted to be replaced. Please forward a maintenance receipt for these repairs to this office
once they are completed.
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 not evaluated for proper
operation. The spray field vegetative cover was in good condition, there was no evidence of
surface runoff or ponding. All spray heads were intact and appeared to be in good operational
order.
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 five years 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.westcottOncdenr.gov or 919-791-
4247.
