Subject: Response to (NOV-2024-LV-0039) October 2023 & (NOV-2024-LV-0045) November 2023
for Bennett Elementary School wastewater system facility. Permit # NC0039471
Dear Ms. Manuel and Mr. Zhang:
The referenced NOV is for Ammonia Nitrogen (NH3) monthly average exceedance. All other permit
parameters were within permit limits, and the effluent discharge is free from solids and clear in color.
The influent concentrations received by this small system can fluctuate daily. The Ammonia Nitrogen
levels are below the permit daily limit and the system appears to be operating properly. Being NH3 is
sampled twice a month, it only takes one sample that is elevated to cause a monthly average
exceedance. I believe this exceedance is due to the seasonal temperatures changing. Adjustments have
been made to increase the recirculation rate. This should increase aeration in the water and help achieve
additional Ammonia Nitrogen removal.
We respectfully request that any penalty for this violation be waived.
Thank you for your consideration and please contact me with any questions.
Sincerely,
Adam Pickett
Bennett Elementary School-ORC
