January 13, the CCRA attended the Highland Creek Treatment Plant
Neighbourhood Liaison Committee (HCTP NLC) meeting at 43 Division. Below
is a summary of key updates provided at the meeting by City staff.
Environmental Assessment: Update
part to the efforts of the CCRA, members of the liaison committee and
other community associations (with over 1,800 petitions submitted),
Council voted in November 2013 to reverse its decision to truck sludge at
the treatment plant and instead begin a new environmental assessment.
Thank you again to residents who supported the CCRA’s efforts. This is a
wonderful result. The process will now restart from the beginning and
assess all methods of disposal of sludge at the plant, including new
methods and technologies that have been created since the last
environmental assessment was completed in 2009.
staff advised that the deadline to submit a Request for Proposal (RFP)for
the environmental assessment expired on Friday, January 10. Three
proposals from consultants were received. These proposals will be reviewed
by City staff over the next month. A proposal will be selected by staff by
early March, after which the recommended proposal will go for approval by
City Council’s Bid Committee.
environmental assessment will include an assessment of air, soil and water
as well as a health impact study conducted independently by Toronto Public
Health. It is expected that the environmental assessment will take one
year to complete. Once a consultant has been selected to begin the
environmental assessment, City staff will work with the consultant to
identify opportunities for public consultation. It is expected that there
will be two public meetings as part of the environmental assessment. The
CCRA strongly supports the need for full public consultation in the

the environmental assessment process gets underway.

Odour Control Project
present, odour control measures have been put in place to reduce odour
coming from the plant. In 2013, city staff received three odour
complaints. Worst-case scenarios through modelling have odour units
ranging from 40 odour units in areas directly surrounding the plant to
only 2.5 units in areas furthest away from the plant. These odour units
are in most cases not noticeable to the average person.
further reduce odour units and levels, city staff have embarked on an
odour control project. A consultant has been hired and has developed a
plan to reduce odour levels to 2.5 to 5 units in a worst-case scenario
(e.g. a hot summer day). This project will begin in Summer 2014 and finish
in Fall 2017. The improvements will be compatible with whichever method
Council chooses to pursue to process sludge at the plant (e.g.
incineration, trucking etc.). The project will cost $70 million.
