Peat Mining Impacts

Peat Mining Operations

Peat was mined at Wingecarribee by Emerald Peat Pty Ltd. This was done by dredging it from a floating pontoon with a dragline. The pontoon floated on a pool of water (the dredge pool) created by the hole left by the removal of peat.

The extracted peat was mixed with water to form a slurry that was pumped to a processing plant. There it was dewatered using presses. The processing water was transferred to a series of sedimentation ponds in a disused quarry where the solids were settled out and the remaining water returned to the swamp.

Mining converted peatlands to open water and because the axis of the swamp had a slope of 1:300, the upstream bank of the dredge pool tended to dry out and crack and become potentially unstable (see environmental impacts and causes of environmental impacts).
