Australia’s south east coal mines in Queensland have met new water discharge guidelines established by the Department of Environment and Resource Management and the Queensland Resource Council.

Heavy rainfall in the region allowed the mines to put new water quality standards to the test.

The guidelines have been created following apprehensions over water quality of the Fitzroy River system after huge amounts of water were discharged from mines during floods in 2008.

All 42 coal mines in the Central Queensland region agreed to follow the new requirements, which will help monitor, regulate and manage water discharge.

Queensland Sustainability Minister Kate Jones said water discharge levels over the past week were within acceptable limits and all coal mines have been compliant so far.

“The new conditions are working and that’s a good outcome for the people of Central Queensland,” Jones said.
