An oil spill off the coast of Santa Barbara, California, has leaked some 21,000 gallons into the Pacific Ocean. The Coast Guard has enacted an emergency cleanup after the spill left an oil slick on close to four miles of beach and 50 yards into the water. The company behind the spill, Plains All American Pipeline, has shut down the ruptured pipeline. Meanwhile in Louisiana, a state of emergency has been declared near Baton Rouge after a cargo train with oil tankers derailed.
