But under a structure known as the incident command system, no single entity has overriding authority in confronting the Gulf of Mexico oil spill, a spokesman for the effort said Thursday.
'There's not one in charge over the other,' Coast Guard Petty Officer Cory Mendenhall said. 'It's being run by a unified command.'"
