SAN DIEGO (CBS 8) - The U.S. Coast Guard, California Fish and Wildlife and OSRO personnel evaluated the effectiveness of deploying a boom across the San Diego Bay Tuesday morning. 

The goal of the exercise was to see whether or not the boom can be effectively used to contain oil in the event of a large oil spill in the bay. Officials say no oil or petrol products were used during the exercise, only the deployment of the boom.

The boom was staged and deployed from the Embarcadero Marine Park, spanning the bay from the park to Coronado Island.
