Re: Annual Reporting as per C of A#6348—7QAJBF for the Port Burwell Wastewater
Treatment plant.
Dear: Madam Neary
The following is a summary of the year 2014 operations for the Port Burwell Wastewater
Treatment Plant, owned and operated by the Municipality of Bayham in accordance with
the conditions set out in section#10 (6) of the above said C of A.
Section
a. The attached spreadsheet entitled Annual Compliance Summary captures the
monthly treatment performance of the wastewater treatment plant along with
compliance and objective criteria met. It can be noted that all compliance and
objective criteria were met for the reporting period.
b. There were no significant operational problems encountered in 2014.
c. All equipment was maintained on a routine basis, following manufactures
recommendations and or past operating history. These records are available at
the wastewater treatment plant for review at any time.
d. Daily in house lab work and visual inspections of the treatment process are the
tools used to make adjustments for continued effluent quality. Increased and
consistent lab work by operations staff will ensure optimum plant
performance, and minimize environmental impacts.
e. Flow-metering equipment is calibrated on an annual basis. The calibration
reports are available at the wastewater treatment plant for review at any time.
The in house lab equipment is calibrated on a regular basis by operations staff.
f. See attached spreadsheet for the effluent objectives that were met during the
2014 reporting period. Increased process control by way of operator
monitoring will ensure that objectives are consistently being met. Proper
mixed liquor solids, temperatures, and dissolved oxygen monitoring ensure
the nitrification process.
g. A total of 429m3 of biosolids was spring applied to NASM plan site#20515
and a total of 445.5m3 was fall applied. There are no anticipated increases in
volumes for 2015. Records are available for review at the wastewater
treatment plant.
h. A sulphide reducing chemical known as Bioxide is being injected into the
system at various locations in the collection system which has proven to
successfully reduce odour while reducing collection system corrosion. There
were no complaints related to the process during 2014.
i. There were no overflow or by-pass events experienced for 2014.
Please do not hesitate to call me with any question or concerns at 519-874-4761.
Sincerely,
Ed Roloson, CMM III, ORO
