A couple of litres of light fuel oil spilled into sea from OL3 construction site

A spillage of oily water was detected on 8 April from one discharge pipe of a storm drain on the Olkiluoto 3 construction site. TVO's fire brigade plugged the pipe, laid out a containment boom in the cove and absorption booms on the shores.

The fire brigade is monitoring the situation. At its most extensive oil was detected over an area of ca. 150 m2. The area has continued to decrease as a result of e.g. evaporation of oil.

The amount of light fuel oil spilled into the sea has been concluded to have been minor, less than two litres.

At the moment there are only some small, random patches of oil within the sea area enclosed by the containment booms. The booms will remain in place at least over the weekend. Investigations of the cause of the oil spill continue.

The environmental impact of the oil spill is extremely small.
