The levy on disposing of dangerous asbestos waste up to 250 kilograms would be dropped under a NSW government proposal.

Up to eight per cent of illegally dumped waste across NSW is asbestos waste, the government said, adding that it posed a threat to health and the environment.

Environment Minister Matt Kean said he wants to make it easier and cheaper for people to lawfully dispose of such waste by removing the levy on up to 250kg of separated, bonded and wrapped asbestos waste.

Currently there is a $143.60 per tonne levy on waste in metropolitan areas and $82.70 per tonne in regional areas.

The NSW Asbestos Waste Strategy 2019-21 also sought to discourage people from dumping asbestos waste illegally.

“We will monitor repeat offenders with GPS trackers to deter illegal dumping and cancel vehicle registration for people caught doing the wrong thing,” Mr Kean said in a statement on Tuesday.

Individuals can be fined up to $500,000 for illegally dumping asbestos, while corporations can face a penalty of $2 million.
