Mine discharges 'low risk': Govt
THE risk of environmental harm from mine discharges in the Fitzroy River, that breached Environmental Authorities, was low, a Department of Environment and Resource Management spokesman said yesterday.
The department's mine operations general manager Andrew Connor, said that was due to the quality of the water released and the large amount of dilution that occurred.
Responding to questions from The Bulletin, Mr Connor said Saraji and Capcoal mines had notified the department they had released water outside their licensed conditions.
However, he did not say why the community and the council were not told of the breaches or other discharges.
It was understood a response to that would be provided.
"The Saraji mine released water for a period of two hours," Mr Connor said.
The release was discontinued as it exceeded its 1000 uS/cm authorised limit.
The Capcoal notification related to the overflow of a sediment dam during heavy rainfall. Mr Connor said the water was "heavily diluted by runoff and monitoring indicates no adverse effect on water quality, with EC measured at 142 uS/cm".
