Steam will soon be rising from tar ponds site
Sydney - People travelling near
the Sydney tar ponds over the next
few weeks may see some steam rising
from the site.
The Sydney Tar Ponds Agency
announced Thursday that the cooling
pond project is more than 50
per cent complete and contractors
are preparing to manage ice that
accumulated over the cooling pond
The method selected is adding
Quicklime — a non-combustible
and odourless material — to the ice
pile over a three-week period.
Quicklime was selected as an effective
melting agent because it reacts
vigorously with water, generating a
significant amount of heat to melt
the ice, the agency said in a release.
Throughout the melting process,
the public will see non-hazardous
steam rising from the site. All sediment
will be captured and returned
to the cooling pond to be solidified
The controlled melting activity
will continue only when prevailing
weather conditions are acceptable.
As with all construction activities,
the agency’s comprehensive air
monitoring program is in effect and
will continue as the work proceeds.
