"The U.S. Coast Guard is now saying it is responding to reports of two oil sheens in San Pablo Bay near the Phillips 66 refinery. Officials have not said how much oil has spilled, and investigators have not determined the source of either spill.
In a statement, the USCG says a helicopter crew spotted a sheen just over a mile long by 40 yards wide during a flyover at 7:40 a.m. today. Investigators from the Coast Guard and the California Office of Spill Prevention and Response are aboard a small boat taking samples to help determine the source.
A Coast Guard flyover near the Phillips 66 Rodeo Refinery Marine Terminal identified the second sheen. Cleanup crews have placed 1,000 feet of boom on the water surrounding the refinery, and several vessels and skimmers are on scene conducting containment and cleanup operations. No oiled wildlife has been observed yet."
