Dear Mrs. Lindsey:

On May 11, 2022, Dorothy Robson from the Raleigh Regional Office visited your single-family
residence (SFR) wastewater treatment and irrigation system to evaluate compliance with the
Nondischarge Permit WQ0034596. The assistance Ms. Anne Lindsey and Bob McDonald from
McFarlan Septic provided was greatly appreciated.

Division records indicate a treatment system consisting of a 1,200-gallon baffled septic tank; a
2,000-gallon dosing pump tank with a 0.3 horsepower (hp) transfer pump; two 100.8 square
feet vegetated sand filters; a 4,000-gallon storage/irrigation pump tank with a 0.5-hp irrigation
pump; an ultra -violet (UV) disinfection unit; a 0.21 acre drip irrigation area with two zones, a
rain gauge; and all associated piping, valves, controls and appurtenances.

During the inspection, the following was observed:

Schedule (Section I of permit):
1. As a reminder, the Permittee shall submit a permit renewal application no later than
August 4, 2027

Performance (Section II):
2. The facility meets the performance standards as stipulated in Section II of the permit.

Operation and Maintenance (O&M) (Section III):
3. The permittee is responsible for the O&M of the entire treatment and disposal system
(Section III. 13). Although there is an O&M Plan with McFarland Septic to service the system
twice a year and to respond to alarms, as needed, the system shall be inspected monthly to
make certain of the proper operation of the spray heads, that the system is free of leaks,
that the vegetative growth allows a proper spray pattern, that the soil is assimilating the
disposed treated wastewater with no surface runoff, and that no objectionable odors are
being generated. In addition, the ultraviolet (UV) disinfection unit shall be checked weekly
to ensure proper operation. During the inspection, the UV unit was not functioning. This

irrigation area, as stipulated in the permit. Within 30 days receipt of this letter,
submit a written response to this office indicating actions you will take, or have
taken, to ensure this issue will be avoided.

number [phone], as soon as possible, but in no case more than 24 hours, or on the
