Location

The Chain Valley Coal Project will enable the continuation of underground mining operations at the Chain Valley mine within the area covered by existing mining leases. The planned mining areas are located in the Swansea-North Entrance Mine Subsidence District. This includes parts of Gwandalan, Summerland Point and Chain Valley Bay. Mining will also occur under parts of Lake Macquarie.

From the early 1960s to 1997 much of the application area, including Gwandalan and Summerland Point, was mined beneath in the Wallarah Seam.
