An independent report has confirmed some areas of Darwin Harbour have been polluted during loading of a ship with copper concentrate from mining company OzMinerals.
The Northern Territory Government is investigating a spill of up to 70,000 litres of petrol from a tank at Rio Tinto Alcan's Nhulunbuy alumina refinery on the Gove peninsula, just a few months after the company dumped tonnes of alumina into Gove Harbour.
The NT Government's introduction of a bill doubling environmental penalties has prompted NT Shadow Treasurer John Elferink to warn it presents 'a viability problem' for Darwin Port Corporation.
The Northern Territory will boost pollution penalties in the wake of a spill at BHP Billiton's Gemco manganese mine that the company did not report for 10 days and will also strengthen its environment department's compliance section.
The Northern Territory's Environment Centre has called for a halt in loading of copper concentrate at Darwin Port until the initial investigation into two separate pollution incidents at the facility has been completed.
