Hanna is in custody after being arrested and extradited from Victoria to face the NSW Land and Environment Court last week on charges of illegal dumping brought forward by the NSW EPA.
In late 2016, the EPA began prosecution action in the NSW Land and Environment Court against Hanna for eight repeat waste offences. These relate to the alleged illegal dumping of waste, including asbestos, on private properties in western Sydney in 2015 and 2016.
Each charge carries a maximum penalty of $250,000 and/or two years imprisonment.
Hanna's failure to attend court on several occasions in relation to these charges led to a warrant being issued for his arrest.
The EPA says he pleaded not guilty to the charges and is expected to apply for bail when he reappears in court on Wednesday.
"I would like to thank the NSW and Victorian Police for their cooperation and assistance in bringing Mr Hanna before the court so he can face these serious charges," EPA acting chair and CEO Mark Gifford said.
"The NSW EPA takes illegal dumping very seriously. This crime creates an unacceptable risk to human health and the environment."
An individual can be fined up to $1,000,000 and/or receive a seven-year prison sentence for wilful dumping offences, and $500,000 or a four-year prison sentence for negligent offences.
A corporation can face up to $5,000,000 for wilful offences and $2,000,000 for negligent offences.
There are also on the spot fines that apply for illegal dumping: up to $7500 for an individual and up to $15,000 for a company.
