The City Council says most of the marine gas oil which spilt into the River Lee this morning has been removed.
Up to 20 litres of marine gas oil or MGO is estimated to have been released into a 'limited area' of water at Horgans Quay - away from Cork Harbour’s environmentally sensitive areas.
The release happened at around quarter to ten this morning - during a transfer from a road tanker to a fishing vessel on the Quay.
Three boons were used to absorb the MGO and one boon is currently removing the final pocket of oil.
City Council teams - in a joint operation with the Port of Cork - used peat absorbent to extract the oil.
The boons will remain in the river over the weekend.
Cork City Council staff have been at the site across the day and an investigation is ongoing.
