SUBJECT: Response to Notice of Violation & Intent To Assess Civil Penalty
Tracking Number: NOV-2021-LV-0282
Permit No. NC0049867 - Cleveland WWTP -Rowan County
Dear Mr. Basinger:
Limit Exceedance Violations: 2/6/21 Value 12,000 and 2/13/21 Value 5,400 - Effluent Coliform,
Fecal MF, MFC Broth, 44.5 C (31616) Weekly Geometric Mean Exceeded. All test results since
February 13 have been between 1 to 84.
Over the last six months we have had several problems exceeding the coliform, Fecal limits. This
started with our new Wastewater Treatment Plant (WW IP) 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 engineering action.
Our objective is to operate the Cleveland WWTP within the quality limits and maintain close
follow through with environmental protection.
Sincerely,
Patrick Phifer
Mayor
