Amplify Energy announced that on Saturday, October 2, 2021, Beta Offshore (a subsidiary of Amplify Energy) first observed and notified the US Coast Guard of an oil sheen approximately four miles off the coast in Southern California and initiated its Oil Spill Prevention and Response Plan. 

An estimated 126,000 gallons (572,807 liters) of heavy crude leaked into the waters off Orange County starting late Friday or early Saturday, when boaters began reporting a sheen in the water, officials said. The pipeline and operations at three off-shore platforms owned by Houston-based Amplify Energy Corp. were shut down Saturday night, CEO Martyn Willsher said.

The spill originated from a pipeline off the coast of Huntington Beach connected to an offshore oil platform known as Elly.

Oil from the spill also infiltrated Talbert Marsh, a 25-acre ecological reserve in Huntington Beach that is home to dozens of species of birds.

Officials said Sunday afternoon that it appears the pipeline has stopped leaking. But Orange County Supervisor Katrina Foley said despite efforts to patch the damaged pipeline on Saturday, oil continued to spill from it through the night and divers were still working to repair it early Sunday.
