Authorities in southern California are investigating a 2.5-mile long oil sheen that emerged off the Huntington Beach.

The oil sheen was discovered that spanned 2.5 miles in length and 0.5 miles in width, roughly 2.8 miles off Huntington Beach near platforms Emmy and Eva, the U.S. Coast Guard reported.

“The Coast Guard is contacting all potential spill sources in the area, but no source has been identified,” the Coast Guard said.

Additionally, the Coast Guard has hired an oil spill response organization to conduct offshore oil collection and is working to identify possible impacts to the shoreline and environmental protection strategies.

As it is reported until now no oiled wildlife has been observed.

A Coast Guard helicopter also conducted an overflight in the area at sunrise. Furthermore, the Coast Guard pollution responders on March 8 got underway with a Newport harbor patrol boat to investigate.

Now a unified command has been established in response to an oil sheen observed offshore of Huntington Beach Thursday evening.

The unified command consists of the U.S. Coast Guard, the California Department of Fish and Wildlife’s Office of Spill Prevention and Response and the Orange County Sheriff’s Department.

To remind, the Coast Guard’s Sector Los Angeles-Long Beach Command Center received a report at 6:50 p.m. Thursday of an unknown substance in the water 1.5 miles off the coast of Huntington Beach.
