The next Neighbourhood Liaison Committee meeting will take place in the new year and all are welcome to participate. Anyone can be added to the meeting notification list by providing Nancy Martins (contact info above) with your Canada Post mailing address.
 

The final odour study recommendations should be finalized in the next two months and will then be sent to the Works Committee and Council for review and approval.  The implementation of the preferred abatement technologies will likely happen over a period of 10 years, due to the size and complexity of the undertaking.  The entire odour control system will likely be divided into Phases to ensure that disruption to other plant improvement projects is minimized.  Where possible the Phases will be prioritized so that the greatest odour reductions can be built earlier.

 

In addition to the odour study,  there are ongoing projects, three in particular which will result in reduced odour emissions - this as a side benefit to the main purpose of replacing older equipment.  The projects include:

 

New Digesters 1 to 6 -  better enclosure and capture of odours (started 2005, completion expected in 2008)

South Primary Sedimentation Tanks Sludge/Scum Collection System Improvements - fewer equipment breakdowns therefore fewer odourous maintenance events (open-air tanks need to be drained for repairs)   (start 2006 - completion expected in 2009)
Sludge Thickening Building New Centrifuges - open-air tanks replaced with enclosed centrifuges (come with built-in odour abatement equipment) (Start 2006, completion expected in 2009)
 
The above ongoing projects will result in some odour emission reductions before the Odour Control Study abatement measures are fully implemented. Odour emission reductions will also be realized after the completion of each Phase of the preferred odour control system. Thus, odour emissions from the plant will start to be reduced from the present with increasing reductions being realized in following years as subsequent Phases are implemented.
