Re: Annual Reporting as per C of A#7337-66YQL4.
Dear: Mr. Orphan
The following is a summary of the year 2006 operations for the Port Burwell Wastewater
Treatment Plant, in accordance with the conditions set out in section#10 (6) of C of A
#7337-66YQL4.
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.
b. There were no significant operational problems encountered in 2006.
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.
e. Flow metering equipment is calibrated on an annual basis by R & R
Instrumentation. The calibration report is 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
2006 reporting period.
g. Sludge is hauled to land under C of A#S-0513-41. A total of 676.5 m3 was
hauled in the spring to a total useable area of 19.4 hectares located at Conc.2
South part lot 11 & 12 in the Municipality of Bayham forming part of Elgin
County. 475 m3 of sludge was pressed and stored in our digesters as weather
conditions prevented the fall land application. This sludge will go to land in
the spring of 2007. Sludge records are available for review at the wastewater
treatment plant.
h. Complaints received during 2006 were specific to odour in the wastewater
collection system. Wastewater is pumped from various serviced areas via
pump stations and force mains. Odour accumulates in the force mains due to
the size, length and low flow of some of the serviced areas. As oxygen
depletes in the force mains sulphides increase causing the said odours. 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 complaints.
i. There were no by-passes, spills or abnormal discharge events to report during
this period.
Please do not hesitate to call me with any question or concerns at 519-874-4761.
Sincerely,
Ed Roloson
Water/Wastewater Superintendent
