22 July 1972 



Portland, ME 



No, 6 Fuel Oil 



100,000 gallons 



Tanker struck submerged ledge in Casco Bay, 

 Maine 



Several miles of sand beaches on mainland were 

 lightly contaminated. About one mile of rock 

 and sand shoreline was severely contaminated 

 on Long Island. 



North Island: A crane operated dragline and a 

 bulldozer was used to remove the surface of 

 the beach down to a depth of 6 to 16 inches. 

 A 6-yd-^ front-end loader was used to transport 

 the accumulated spoil to a barge which 

 supported two clam shell cranes. The cranes 

 transferred the spoil into a second barge which 

 was used to transport the spoil to a dump site. 

 The barge was required to compensate for the 

 extreme tidal movement in the ocean. Hot water 

 jets were used on rock outcroppings to remove 

 adhering oil. The treatment left a uniform 

 black discoloration on all the rocks. A flame 

 thrower was tested but it caused spalling of 

 rocks, and its use was discontinued. Oil- 

 contaminated seaweeds growing on rocks were 

 cut off and new growth appeared within one 

 week, Portland: Hay was applied to the oil on 

 sandy beaches and then removed manually ,
