Dear Mr. Duncan:
The North Carolina Division of Water Resources conducted an Bioassay Compliance inspection of the Robersonville
WWTP on February 8, 2022. This inspection was conducted to verify that the facility is operating in compliance
with the conditions and limitations specified in NPDES WW Permit No. NC0026042. A summary of the findings and
comments noted during the inspection are provided in the enclosed copy of the inspection report.
The following violations were noted during the inspection:
Inspection Area Description of Violation
Secondary Clarifier
On the day of inspection the #5 Clarifier and #6 Clarifiers needed repairs. The #5
Clarifier arm was not working and the clarifier was online. ORC stated that a shear pin
had broken and they are working to have this repaired. The #6 Clarifier was down and
was not operational. James stated that the gear box for the clarifier arm was damaged
and that the gear box had to be rebuilt. The estimate for replacing the gear box was
approximately $70,000 and they are going to bring this to the Town Council for approval.

Inspection Area Description of Violation
Equalization Basins
The "equalization basin" is an anerobic and anoxic zone. On the day of inspection the
mixers were off and there was an excessive amount of solids and vegetation on the top
of the basin. The ORC stated that the mixers were off because with all the solids and
vegetation the mixers will plug. With the mixers not running the basin is acting as a
settling basin and this is not the intent of this basin. The ORC stated that the basin will be
cleaned out in March 2022
Remedial actions should have already been taken to correct this problem and prevent further occurrences in the
future. The Division of Water Resources may pursue enforcement action for this and any additional violations of
State law.
To prevent further action, please respond in writing to this office within 30 days upon your receipt of this Notice
of Violation regarding your plans or measures to be taken to address the indicated violations and other identified
issues, if applicable.
If you should have any questions, please do not hesitate to contact Robbie Bullock with the Water Quality
Regional Operations Section in the Washington Regional Office at 252-946-6481 or via email at
[e-mail].
