Minor oil spill shuts down Trevallyn station

Hydro Tasmania has shut down its Trevallyn Power Station as a precaution, after a member of the community noticed and reported oil sheen on the surface of the tailrace (below the power station) before it enters the Tamar River.

The spill is estimated at between five and 10 litres in volume. Hydro Tasmania is investigating whether it originates from the power station itself, or an external source such as diesel from a nearby boat motor.

Hydro Tasmania is using an oil boom to contain the spill, and expects it be cleaned up in the next few hours.
