When Phillips 66 this week announced its plans to close its Los Angeles-area refinery in late 2025, many observers noted the announcement came just days after California Gov. Gavin Newsom signed a new law aimed at refineries.

"Phillips 66 remains committed to serving California and will continue to take the necessary steps to meet our commercial and customer demands." Operations are expected to shut down in the fourth quarter of 2025. The Carson operation was built in 1923.

Phillips 66 announced it will shutter its Los Angeles-area refinery by the end of 2025, just days after the California governor signed a new law tightening restrictions on oil and gas companies. The refinery accounts for about 8 percent of the refining capacity in the state and employs approximately 600 workers and 300 contractors in the 650-acre facilities.
