Dear Mr. Boss:
In October 2023 Brad McKinney took over as ORC for the Tryon Wastewater Treatment Plant and
resigned June 2024. At the present time I'm the ORC until the Town hires someone. Please find below
the causes and corrections for Notice of Violations:
Fecal Coliform/Weekly Geometric Mean Exceeded:
• Cause : Not wasting enough sludge, causing sludge blanket to rise in clarifiers.
The chlorinator was showing the chlorine was feeding but the operating lever
was not pushed down to the correct position.
• Correction: Wasting sludge on our normal schedule Monday, Wednesday, and Friday.
Set chlorinator to correct position.
Total Ammonia Nitrogen/Weekly Average exceeded;
• Cause: Not enough time on aerators and mixer and not wasting enough sludge.
• Correction: Added extra time to the aerators and mixer in the activated sludge basin to
increase the dissolved oxygen and wasting more sludge on our normal schedule,
have taken remedial actions to correct the above problems and prevent further occurrences in the
future.

If you have more questions, please contact me at debmbrad leylShotmail.com.
Sincerely,
Deborah Bradley, O€iC J
Tryon WWTP
