Marathon Flaring at Los Angeles Refinery to End Dec. 9

SECAUCUS, NJ (DTN) – Marathon Petroleum has reported a planned flaring at its 365,000 bpd Los Angeles refinery in Carson, California, that is expected to end Tuesday (12/9), according to an emission report sent to the South Coast Air Quality Management District.

The report said the flaring began at 10:04 p.m. PT on November 21 and was scheduled to stop at 11:59 p.m. PT on December 9.

Marathon listed the reason for the flaring as “start-up/shutdown”, which typically refers to a planned event.

The flaring occurs against a backdrop of diminishing refining capacity, heightened regulatory pressure, and concerns over fuel supply stability in the West Coast market.

Marathon reported a mechanical malfunction event at the Los Angeles refinery in early December, leading to multiple flaring episodes.
