Annotation
A proposed pipeline from Dooleys Hill near Latrobe to Port Sorell will encounter no potentially unstable zones. The rocks along the route include Quarternary sediments, Tertiary sediments and basalt, Jurassic dolerite and Permian sediments. Trenching in the dolerite will be difficult and expensive, some of it cannot be avoided without major rerouting, but two minor diversions are suggested near Appleby Creek. Like its counterpart on Dooleys Hill, the reservoir near Port Sorell will have no solid rock foundation. Extensive and expensive blasting will be needed on Staggs Hill unless the pipeline is laid on the surface.
