State regulators have released previously withheld details in reports filed by Pacific Gas & Electric Co. revealing the exact location of damaged transmission equipment found near the ignition points of the wildfires that ravaged Sonoma and Napa counties in October. The documents — including the precise address and specific types of damaged equipment — provide new information about the proximity of PG&E equipment to the origins of the deadly Oct. 8 fires. Cal Fire officials say their investigation is not complete, and PG&E officials stressed no causes of the fires have been identified. Nevertheless, dozens of lawsuits have been filed against PG&E alleging the fires were sparked when gale force winds sent overgrown tree limbs crashing into powerlines.
