Los Angeles County sued Edison International to recoup its losses from a January wildfire that was one of the most destructive in California history.

The suit alleges that equipment owned by the company’s Southern California Edison utility caused the Eaton Fire. The county claims it’s been saddled with hundreds of millions of dollars in costs to respond to the blaze and repair damaged infrastructure and property. The cities of Pasadena and Sierra Madre filed separate suits against Edison in Los Angeles County Superior Court.

Edison is facing mounting scrutiny for the possible role its power lines may have played in the Eaton wildfire that burned more than 14,000 acres, destroyed about 9,400 structures and resulted in 17 deaths. The company already faces dozens of lawsuits alleging its equipment sparked the blaze in the Pasadena foothills that was fanned by high winds during an outbreak of wildfires that charred parts of the Los Angeles area.
