Cleanup crews clean vessels that assisted in Refugio oil spill response at a decontamination station in Ventura, Calif., June 7, 2015. Several vessels were demobilized from the incident after days of not finding oil in the surrounding waterways; eight vessels remain on scene to monitor for oil and will do so until all cleanup operations are finished.
