Dear Mr. Basinger,
On behalf of The City of Albemarle, I would like to thank you and the staff of the Mooresville
Regional Office for the opportunity to provide additional 'information for the NOV dated April 23, 2019,
listed above.
Over the winter of 2018-2019 Albemarle and the surrounding areas have had extreme amounts of
rainfall. The City of Albemarle Long Creek W WTP has certainly felt the effects of this as well. These
heavy rains, and inflow & infiltration associated with these events have been detrimental to the treatment
process. We, here at the treatment plant, make numerous process changes to the operation during said
events. These changes include, putting the entire plant into operation, reducing aeration, and flow
equalization. These changes do produce positive, yet limited results. Ultimately, MLSS concentrations
have been "washed out", despite our adjustments. This has resulted in NI13 concentrations that have
exceeded our NPDES permit limits.

On 4-1-19, we started feeding a coagulant at each clarifier during normal operation. The
results of this have been limited. We are currently still feeding the coagulant to aid settleability at each
clarifier.
To date 5-10-19, we have seen a drastic amount in Chlorine demand entering the Chlorine contact
basin (indicating a high presence of Nitrites). This is a step in the right direction.
Again, I would like to thank you for your continued cooperation regarding these issues. If you
and/or your staff would like any additional information regarding these matters, please feel free to me at

Sincerely,
