Subject: Compliance Evaluation Inspection
Chapel Ridge WWTP Collection System
Deemed Permitted Collection System No. WQCSD0267
Chatham County
Dear Ms. Becker:
On August 18, 2022, Alys Hannum of the Division of Water Resources (Division) conducted an
inspection of the Chapel Ridge Collection System to evaluate compliance with the operation and
maintenance of the subject deemed wastewater collection system permit. The cooperation and
assistance of Peter Rhodes, Field Supervisor II with Aqua North Carolina, during the inspection
was greatly appreciated.
The Chapel Ridge Collection System is covered by a deemed permit (WQCD0267) and is
classified as a CS-1 system. Deemed collection systems must meet the requirements of 15A
NCAC 02T.0403. If the system ever exceeds 200,000 GPD, Chapel Ridge would need to apply
for an individual collection system permit.
Findings during the inspection were as follows:
1. The wastewater collection system consists of five pump stations and no high priority
sewer lines. All five pump stations have permanent on -site generators and are connected
to telemetry.
2. Aqua North Carolina has developed and maintains a map of the collection system on its
GIS system. Please ensure the map is updated to include: pipe material, pipe age, and
pump station capacity.
3. Division records indicate no sanitary sewer overflows (SSOs) to State Waters during the
most recent 2-year period ending July 2022.
4. Aqua North Carolina has developed and maintains an organization -wide Emergency
Response & Operation and Maintenance plan including pump station inspection
frequency, preventative maintenance, spare parts inventory, and SSO overflow response.

5. Aqua North Carolina has developed and maintains an organization -wide Fats, Oils, and
Grease (FOG) program which includes the bi-annual distribution of educational materials
to commercial and residential users. The program includes the legal means to take
enforcement against users who have not properly installed, operated, and/or maintained
grease traps or grease interceptors, or who have otherwise violated the program.
6. All five pump stations were inspected. All had clear rights -of -way, secured access,
appeared in good condition and were free of excess debris. All audible and visual alarms
are tested weekly by operators. Notes are as follows:
a. Station #1 — The back-up generator did not start manually but did start during a
simulated power -loss.
b. Station #2 — Nothing of note.
c. Station #3 — Nothing of note.
d. Station #4 — The chemical feed building does not have an eyewash station. All
other stations do have eyewash stations.
e. Station #5 — Station is not currently in use and is for future planned expansion.
The station does not have any identifying signs and the fire extinguisher in the
chemical feed building is expired.
7. A logbook for each pump station was available to view during the inspection. Pump
station maintenance logs were reviewed and appeared satisfactory. Pump stations are
inspected at least once a week by the ORC.
If you have any questions concerning this report or the required submissions, please contact
Vanessa Manuel at [e-mail] or by phone at [phone].
Sincerely,
