Dear Mackey Lambert,

On February 9, 2024 Staff from the Raleigh Regional Office visited your single-family residence (SFR)
wastewater treatment system to conduct a startup inspection and evaluate compliance with the subject
Non-Discharge Permit. The assistance of Tyler MacConnell of MacConnell and Associates and Jason
Stephenson and Keith Whitfield of ConMech Industries during the inspection was helpful and
appreciated.

Non-Discharge Permit WQ0043910 was issued April 27, 2023 and will expire on September 30,
2029.

Our records indicate the treatment system consists of a 1,000 gallon baffled septic tank with effluent filter
and sanitary tee, a 1,000 gallon E-Z Treat recirculation tank with an audible/visual high-water alarm and a
13.6 gallon per minute (GPM) recirculation pump, a Model 600 (600 GPD capacity) E-Z Treat Treatment
Pod, a 10 GPM ultraviolet (UV) disinfection unit, a 4,500 gallon field dosing tank with an audible/visual
high-water alarm and a 12.4 GPM field dosing pump, a control panel with rain/moisture sensor, a
hydraulic unit, a meter vault with a two-zone flow splitting valve, a 0.234 acre drip irrigation area
consisting of two zones, and all associated piping, valves, controls, and appurtenances.

Non-Discharge Permit WQ0043910 authorizes the operation up to 360 gallons per day (GPD). The
authorized irrigation is in accordance with the effluent limits and monitoring requirements established
within the Non-Discharge Permit.
The system appeared to be well installed with all components of the system as detailed in the permit
included.
The drip field did not have any cover crop planted. A competent vegetative cover needs to be
installed prior to operation of the system. Additionally, Permit Condition I. Schedules 1. states
“Upon completion of construction and prior to irrigation, a North Carolina licensed Soil Scientist
shall conduct a soil evaluation of all irrigation areas with placed fill material. The evaluation shall
certify that irrigation areas using fill material can accept the permitted loading rate. This
evaluation shall specifically address soil features such as soil compaction and saturated hydraulic

conductivity of the least permeable layer; soil fertility and amendments added; verification of fill
suitability and depth of fill material to the ground surface and the seasonal high-water table; and
any other properties that might impact the soil's ability to accept irrigated effluent. The Permittee
shall submit the Soil Evaluation via the Non-Discharge online portal. The Permittee shall not
operate the wastewater irrigation system until
the Raleigh Regional Office approves the soil evaluation. [ 15A NCAC 02T .0108( b)( 1)( A)]”

I have not been able to locate the LSS evaluation of the disposal area that is required after the fill
material was added and incorporated in our database or files.

Please address these issues and provide the required documentation prior to operating the system.

If you have questions or comments about this inspection or the requirements to take corrective action (if
applicable), then please contact Chris Smith at 919-791-4257 or at [e-mail]

Sincerely,

Michael Hall, Regional Supervisor
