Tanker struck cerebrus rock, broke up and sank 

 releasing oil from forward part of ship. 



About 150 miles of shoreline were contaminated 

 of which 30 miles of beach were cleaned. 



Deep Cove: A bulldozer was used to remove 

 contaminated sand. Spilled contaminated mate- 

 rial became thoroughly mixed with clean beach 

 sand. Arichat: A contractor used a fixed blade 

 bulldozer (tracked) and a skid shovel to remove 

 contaminated sediment to a depth of 12 to 18 

 inches. The bulldozer proved unsatisfactory as 

 the material pushed forward by the blade was 

 mixed with clean uncontaminated material. 

 Spillage around the blade was ground into the 

 beach by the tracks of the vehicle. Blackduck 

 Cove: Contract used a fixed blade bulldozer 

 (tracked) and a wheeled front-end loader to 

 remove 4,500 cubic yards of sandy beach mate- 

 rial. At the extremities of the beach the 

 bulldozer often sank above its tracks in silt 

 and mud resulting in thorough mixing of con- 

 taminated material with clean material.
