Re: NOV-2019-PC-0769
Dear Mr. Snider:
Concerning the above NOV following a Compliance Evaluation for Yonahlossee W WTP, we do
acknowledge that the UV was not operational at the time of inspection; however, we have been
using chlorine and maintaining records of residuals in the interim. We have searched for
replacement parts and were unable to do so in a timely manner, which we sincerely apologize for.
Replacement parts have now been ordered as of December 3, 2019, and an invoice is included as
an attachment to this correspondence in support of that. According to the company we ordered
from, shipment should take place 4-6 weeks after ordering, which may be delayed by the holidays
as well. We are not yet in receipt of replacement parts, but will update Ms. Park as we receive and
install them.
A new flow chart and ink pen have been installed at the plant. In addition, we've attached the
pump logs requested; the plant was pumped on November 27, 2019 due to leaves clogging the
return.
We located a typo on the result printout with reference to the NH3 on August 14, 2019 as the
result was 3.69 and not 5.69 as we had presented at the time of inspection. We have attached the
chain of custody as well as the laboratory's bench sheet in support of this information; the sample
number listed on the chain and laboratory bench sheet is 444. We apologize for the error and will
be more diligent in the future as we review our data and data entry procedures.
Thank you for your time and consideration, as well as the opportunity to correct the deficiencies
noted in the inspection report. Please feel free to contact us if we can be of further assistance.
S' er ly,
