A massive oil spill in the Pacific Ocean has reached the Southern California coast

Oil is seen on the beach in Huntington Beach, California on October 3, 2021, after a pipeline breach connected to an oil rig off shore started leaking oil, according to an Orange County Supervisor.

More than 120,000 gallons of oil that spilled into the Pacific Ocean has reached the Southern California coastline, closing parts of the beach as officials warn residents to stay away from the slick.

Federal, state and local agencies are racing to determine the cause of the spill, which is at least 13 square miles in size, and mitigate its impacts.

“The ramifications will extend further than the visible oil and odor that our residents are dealing with at the moment. The impact to the environment is irreversible,” Orange County Supervisor Katrina Foley said in a statement on Saturday.
