Tellus Holdings has gained approval for an underground repository that will accept up to 100,000 tonnes of hazardous waste annually, and is investigating whether the facility can earn carbon credits.
The Western Australian Opposition says a new regulation will leave many businesses that bring uncontaminated fill onto their sites unnecessarily exposed to waste levy liabilities.
Companies will have new responsibilities to analyse and safely transport their hazardous waste, and tighter controls will apply to the movement of asbestos, under changes proposed by the Western Australian government.
Western Australia's environment department has signalled regulatory changes to ensure a Supreme Court ruling over the payment of waste levies doesn't have unintended consequences.
