Conditions attached to mine extension
A proposal to extend the depth and area of existing mine pits in the Pilbara region has been recommended for approval subject to seven conditions by the Environmental Protection Authority.
BC Pilbara Iron Ore has proposed to revise its Iron Valley Above Water Table Project, about 90km north-west of Newman.
The revised proposal includes the development of a new mine pit, with mining operations extending below the water table, and the dewatering of the underlying aquifer.
EPA chairman Tom Hatton said testing against environmental factors including flora and vegetation, hydrological processes and inland water environmental quality had been undertaken.
“The conditions we have recommended include preparation of an outcome-based environmental management plan to minimise the long-term impacts from groundwater abstraction and surplus dewater discharge run-off, and alterations to surface water flows to Weeli Wolli Creek,” he said.
“Conditions also require the proponent to minimise hydrological impacts to Aboriginal heritage values linked to the creek and to contribute to an approved conservation offsets fund.”
