Hundreds of litres of fuel leaked from the Altona Mobil refinery on Saturday.
Firefighters were called to the refinery at the corner of Millers and Kororoit Creek roads after the leak was detected about 11.30am.
Metropolitan Fire Brigade spokeswoman Heather Stockton said the spill was under control when firefighters arrived.
“We had reports of about 700 litres of product which had leaked from a petrol line that had corroded,” she said.
Mobil spokesman Travis Parnaby said the fuel had been completely contained within a concreted bund.
“There was no impact on staff, the community or personnel,” he said.
“All fuel has since been recovered.
“Mobil will investigate this release and implement actions to prevent this occurring again.”
WorkSafe is making inquiries.
Last November, the refinery had a leak of hydrogen and naptha, a flammable liquid hydrocarbon.
The refinery processes up to
13 million litres of crude oil a day
into petrol, diesel, aviation fuel and LPG.
It underwent a $20 million upgrade this year to increase production from 80,000 barrels a day to 90,000 barrels.
