The new modification will allow for planned mining of an area of over 3300 hectares compared to the previously consented acreage of almost 1900ha.

Illawarra Coal said the consent modification related to the future configuration of the mine until the end of 2030, “providing greater assurance for the ongoing supply of coking coal to the steel industry and direct employment for 270 employees and contractors”

Illawarra sustainable development and external affairs general manager John Brannon said the company was pleased with the approval which will allow for a more sustainable future mine layout in the mine’s Area 3.

“The original consent, approved in November 2001, has been modified in response to what we now know about the mining conditions in the area, and reinforces rigorous environmental controls and standards in relation to natural features such as swamps, creeks and waterfalls,” he said.

“With this approval we have a future mining footprint that will not only help to ensure continued supply of valuable coking coal from the Wongawilli seam and ongoing employment for many local families, but also recognises the importance of environmental features such as Wongawilli Creek.

“This modified consent lays the foundation for a demanding approval process which, coupled with Illawarra Coal’s preparation of comprehensive environmental management plans and monitoring programs, provides the right combination for a sustainable mining industry.”

Illawarra added the modified consent does not remove the requirement for approval of subsidence management plans prior to extraction of coal in future mining areas.

Illawarra communication and consultation manager Rosanne Moore told International Longwall News the company consulted extensively with all relevant stakeholders including government agencies and traditional landowners.

“Mining will not occur beneath any of the area's significant waterways, and mining activity beneath all other surface features will be subject to comprehensive subsidence management plans submitted for approval to the NSW Department of Primary Industries,” she said.

This comes in response to an ABC News report of the DPI saying the modification would impact on streams and watercourses, upland swamps, cliff lines and Aboriginal heritage sites.

Reportedly the DPI said the modification’s economic benefits outweighed environmental costs, so the extension was in the public interest.
