What happened

Marathon Petroleum indefinitely idled its 161,000 bbl/d Martinez refinery in April 2020 amid a collapse in gasoline demand from COVID-19 travel restrictions, initially converting it to a storage terminal before repositioning it as a renewable-diesel facility aligned with California's Low Carbon Fuel Standard, which began operating in 2022. This was a voluntary commercial closure, not an incident or attack.
