Subject: Compliance Evaluation Inspection
The Preserve at Jordan Lake WWTP
Non -Discharge Permit No. WQ0018146
Chatham County
Dear Ms. Berger:
On January 18, 2023, Cassidy Kurtz from the Raleigh Regional Office conducted a compliance
evaluation inspection of the Reclaimed Water Generation and Dedicated Utilization System for
the Preserve at Jordan Lake WWTP. The purpose of this inspection was to ensure compliance
with the conditions and limitations specified in Non -discharge Permit No. WQ0018146. During
the inspection, the cooperation and assistance of Katie Dickens, Eric Riggins, and Jade Wicker
was greatly appreciated.
This compliance evaluation inspection consisted of the following:
Review of the permit,
Review of ORC logbooks, calibration documentation, non -discharge monitoring reports
(NDMRs), non -discharge application reports (NDARs), and
On -site inspection of the treatment components and spray fields.
The current permit was issued May 12, 2020 and expires September 30, 2026.
Components of the wastewater system appeared to be overall well -maintained and operational.
At the time of inspection, water in the upset and irrigation storage ponds was free of floating
solids and plenty of freeboard was available. The backup generator is run on a weekly basis
under load for about 15-30 minutes. Irrigation is typically conducted overnight to avoid contact
with golfers, and signage was posted at the clubhouse. During the inspection, the irrigation areas
for the front nine holes of the golf course were observed, and the sprinklers were activated at
each hole unoccupied by golfers. The observed irrigation areas appeared to have good spray
patterns and even coverage.
The records review portion of the inspection included review of NDMRs, NDARs, Operation
and Maintenance Plan and log, residuals log, calibration records, and educational materials. Lab
results were compared to submitted NDMRs for January and September 2022 (amended NDMRs
were submitted for September); no typographical errors were noted. NDARs were reviewed for

the same months with no errors noted. The Operation and Maintenance Plan and log appear to be
thorough and includes pertinent information. Residuals are hauled every other month and were
hauled on the day of the inspection. The turbidimeter and flow meter were both last calibrated
November 15, 2022. The facility reported no bypasses, spills, sanitary sewer overflows, or public
complaints within the last 12 months.
The Reclaimed Water Generation and Dedicated Utilization System appears to be compliant with
permit requirements. If you have any questions about this inspection or this letter, please contact
