Dear Mr. Basinger:

MOORESVILLE REGIONAL OFFICE
Limit Exceedance Violations: 1/9/21, 1/23/21, 1/30/21 and 1/31/21 - Effluent Coliform, Fecal
MF, MFC Broth, 44.5 C (31616) Weekly and Monthly Geometric Mean Exceeded. The monthly
average test results since February 13 have been between 10.8 to 52.2.
Over the last six months of 2020, we have had several problems exceeding the coliform, fecal
limits. This started with our new Wastewater Treatment Plant (WWTP) operator who felt that the
problem was due to having a chlorine contact chamber that was too small. After he left our
employment in February 2021, we discovered that the bypass valve was not being sometimes
closed all the way. The bypass valve was used to clean the contact chamber. The cleaning
procedure has been used since the WWTP has been in service. It was part of the design of the
WWTP. We certainly did not intend to leave it open or cracked.
The corrective action to prevent any further use of this contact chamber clean -out procedure is:
(1) Discontinue bypass usage and seal valve. (2) Install a temporary pump to be used to recycle
back to the oxidation ditch to clean the contact chamber. This would occur between 5 and 7 a.m.,
our lowest flow rate time. The cleaning should occur as needed, probably once per month.
(3) Proceed with installing a second chlorine contact chamber as soon as possible. See the
attached current engineering action.
Our objective is to operate the Cleveland WWTP within the quality limits and maintain close
follow through with environmental protection.
