Forest service seizes PG&E equipment as part of fire probe

SAN FRANCISCO (AP) — Federal investigators have taken possession of a Pacific Gas and Electric Co. utility transmission pole and attached equipment in a criminal probe into what started a Northern California fire that has become the largest in the state this year, the utility said in a regulatory filing Monday.

U.S. Forest Service officials indicated to PG&E that an initial assessment showed the Mosquito Fire started near one of its power lines on National Forest lands, the Oakland-based utility said in its filing with the Securities and Exchange Commission.

The blaze in the Sierra Nevada foothills, about 110 miles (180 kilometers) northeast of San Francisco, broke out Sept. 6 and has destroyed at least 78 homes and other structures and charred forestland across Placer and El Dorado counties.

Earlier this month, the fire surpassed the size of the previous largest conflagration in 2022 — the McKinney Fire — although this season has seen a fraction of last year’s wildfire activity so far. Fire officials said total containment of the Mosquito Fire is expected around Oct. 15.

PG&E is cooperating with the U.S. Forest Service investigation, which has yet to determine what caused the blaze, the utility said in a statement Monday.

The utility said it is conducting its own investigation into what sparked the blaze and that it doesn't have access to the physical evidence that was collected by the Forest Service investigation over the weekend.
