Dear Mr. Basinger:
',`'E �. t_: �f I i � •`> t1x�,� c 1i i if ;t:.
This letter is in response to the above Notice of Violation received on August 9, 2019. During
June, the BOD results were: 6/5=23.8, 6/12=11.2, 6/20=13.0 and 6/26=14.7. In July, the results
were 7/1=2.63, 7/10=2.08, 7/17=13.8, 7/24=35.1 and 7/31=8.36. See the attached e-mail and
trend chart.
As far as the frequency violation for temperature, a recording error was made on the May DMR
due to the holiday on May 27. A corrected May DMR will be submitted.
Consulting will continue with Withers & Ravenel and Shield Engineering Inc. An engineering
study is being conducted by Withers & Ravenel. They are waiting on an environmental review
for completion of the study.
As you can see, the Town is still working diligently to investigate and solve the BOD issue.
Hopefully, knowledge from the engineering study will help.

Subject: Town of Cleveland high BODs
Good morning, Roberto. This pains me to no end to have to report yet another high BOD result but I
think maybe we can blame it on the rain this time.
Since the last email I sent ya on 6/5/19 we have had excellent BOD numbers but our 7/24 results was a
35.1 mg/l. The only thing I can put focus on is we had rain on the day before sampling day and the
day of. The day before had 1" of rain then the day of sampling had another 1" with .184 and .201 gls
of flow on 7/22 and 7/23. I would not consider these to be extreme flow rates and visually the plant
didn't show any indication of a high flow event. The sample that was sent was clean and clear and all
other sample results both influent and effluent were normal.
I had our lab run a COD of this weeks sample which came back 39.0 mg/l so looks like the BODs will be
back down to normal which makes it appear that it was an isolated event. I'm just very hopeful that
our previous issue is not returning and I have not seen any indication that my plant is showing a
down turn. Have monitored our bug populations and our new PH/ORP probes and have not seen any extreme
swings that would cause concern.
Thank you for your time and I will keep you informed going forward.
Hope you have a great weekend,
Paul Land
