A small amount of water and gasoil was accidentally spilled on the concrete floor during a routine water draining operation on one of the storage tanks at Delimara power station yesterday morning, Enemalta said.
Enemalta said its personnel immediately initiated procedures to contain the spillage.
The corporation said the amount of oil spill registered is minimal at an estimated 10 cubic metres of gasoil and has been successfully collected.
"The spillage was fully contained within the concrete-lined tank bund protecting the tank and no damage to the surrounding environment or underground seepage has been registered. No personnel were injured and no type of damage has been sustained to any equipment," Enemalta said. The competent authorities, including the Malta Resources Authority, Mepa, OHSA and the Civil Protection Department, were informed.
Last month, Enemalta suspended a number of employees after the spillage of 31 tonnes of A1 aviation fuel at the Birżebbuġa-Għar Dalam installation went unreported for a week.
