Workers clean the beach at Refufio State Beach on May 21, 2015 in Goleta, California. California Gov. Jerry Brown declared a State of Emergency after over 100,000 gallons of oil may have spilled from an abandoned pipeline on the land near Refugio State Beach, spreading over about nine miles of beach within hours. The largest oil spill ever in U.S. waters at the time occurred in the same section of the coast in 1969 where numerous offshore oil platforms can be seen, giving birth to the modern American environmental movement.
