Emergency services contained a 6000-litre ethanol spill at a Sydney oil refinery last Friday. The Department of Environment and Climate Change told the ABC the environmental impact would be minimal because, unlike petrol, ethanol dissolves in water.

The ethanol was set to be blended with petrol to become E10. Much of the spill was contained under a foam blanket to prevent ignition, and fuel remaining in the leaking tanker was decanted. There were, however, a bunch of unusually happy fish swimming in the Parramatta River on Friday night.
