Re: Notice of Violation/NOV-2021-LV-0872
NPDES Permit NC0073814 Buncombe County Schools
North Buncombe Elementary School
Buncombe County
Dear Mr. Boss,
This letter is written on behalf of the Buncombe County Schools to provide information
as to remedial action taken to the above referenced facility in reference to NOV letter
dated November 17, 2021 attached.
We received the lab result of 76.2 mg/L BOD for 9/28/21 early in October 2021 and
immediately questioned our subcontracted lab Pace Analytical about the results being
higher than we would expect for this system and all other school WWTP's that day. The
plant showed no indication of a problem. Samples prior and after were compliant.
Likely due to unknown source.
The monthly average was compliant.
I trust you will call if you have any further questions or concerns.
