Dear Mr. Basinger,
We are in receipt of the above -mentioned Notice of Violation and respond as follows.
The BOD sample collected on May 15t" with a result of 9.7mgl exceeded the daily permit limit of
7.5mgl. We exceeded one daily limit but were in full compliance for the month.
After evaluation of the WWTP it was determined that blower number two had a bad check
valve and was allowing solids to backflow back into the clarifier. The check valve has been
replaced and everything is back to normal. All other daily and monthly samples collected
comply with the NPDES permit.
If you have any questions or if I can provide any additional information, please do not hesitate
to contact me at 704-621-9204.
Sincerely,
Charles E. Wood Jr.
