In March 2006, a number of cars were being transported from an island off the west coast of Ireland and destined for the scrapyard.
The cars were left on the shoreline at low tide, for collection.
When the sea came in, the cars were submerged and engine oil, diesel and petrol leaked out of broken sumps and damaged tanks and into the water.
Absorbent pads were applied to the spill on the beach, in a vain attempt to mop up the spill. The issue was that every time the tide came in, it coated the rocks on the shore in fresh oil and diesel.
