Shasta and Tehama filed a lawsuit against Pacific Gas and Electric on Thursday.
The counties are seeking to reclaim costs for injuries and damages to public resources related to the Zogg Fire.
The lawsuit alleges that PG&E failed to remove a hazardous pine tree which, according to the suit, fell on a charged utility line and ignited the fire on Sept. 27.The blaze scorched more than 56,000 acres in Shasta and Tehama counties. It destroyed 204 buildings and killed four people. Cal Fire is still investigating the cause of the fire.
PG&E was notified in October that its equipment was seized as part of that investigation.
