At least four wildfires in Butte and Nevada counties this past October were caused by trees that came into contact with PG&E power lines, according to CAL FIRE investigators.
These are the first findings to be made public from last October's fire season, when more than 170 fires ravaged over 245,000 acres throughout Northern California.
Investigators found the La Porte and Honey fires in Butte County and the McCourtney and Lobo fires in Nevada County to be caused by contact with power lines. In three cases, CAL FIRE found possible violations by PG&E.
The four fires burned more than 9,000 acres and destroyed 134 structures.
In a statement, PG&E said that, based on the information it has so far, it believes its programs met state standards.
