BLACKTOWN Council will decide tomorrow night whether to lobby the state government to drop a waste levy on asbestos to ward off a rise in illegal dumping.
Councillor Charlie Lowles called last month for a report into illegal dumping in 2012-13.
The report is on the agenda for tomorrow night's council meeting.
The report says there were 43 incidents of illegal dumping of asbestos on roadsides and 13 at council-managed open places across the Blacktown local government area in 2012-13.
This was up from 32 roadside and three open space incidents in 2011-12.
Semi-rural areas such as Marsden Park and Riverstone were among the hot spots.
No one has been prosecuted, the report says, because the council relies on the public to notify them about dumping offenders.
It cost the council $130,816.40 to collect and dispose of dumped asbestos in 2012-13, up from $23,482 in 2011-12.
It costs $300 and $470 a tonne to dispose of asbestos at two landfills in the Blacktown local government area.
The reports advises the council to lobby the state government to remove the $107.80 section 88 levy included in the cost.
"The section 88 (waste) levy was introduced as an economic instrument to increase recycling," the report states.
"As asbestos-containing material cannot be recycled, it is considered that it should be exempt from the levy."
Liberal councillor Jackie Donaldson is concerned abolishing the levy would put tip costs up, but Cr Lowles said he hoped councillors would pass the recommendation.
