PG&E is set to enter a plea next month on a criminal arraignment related to the Zogg Fire. On Monday a Shasta County Superior Court Judge denied the nation’s largest utility a demurrer that sought to strike charges of negligent emissions of air pollution. Shasta County District Attorney Stephanie Bridgett filed 31 charges in September, including four counts of manslaughter. Cal-Fire and PG&E have both already acknowledged the fire was caused by PG&E electrical lines that were brought down by a Gray Pine Tree that was marked for removal, but was not removed in time. Just after the charges were filed, PG&E disputed that that particular Gray Pine north of Igo had been identified as a hazard. The Zogg Fire burned more than 56,000 acres, destroyed more than 200 buildings and killed four residents as they tried to escape the flames. PG&E was already on probation for the San Bruno natural gas explosion and the Camp Fire in Paradise. Arraignment is set for June 9th.
