A U.S. judge who has berated Pacific Gas & Electric Co. for its role in California wildfires is demanding more answers from the utility. In a court filing Thursday, Judge William Alsup asked PG&E if it was in compliance with a state law requiring it to clear vegetation around electric lines that could cause fires. The judge also questioned a part of the utility's recently submitted wildfire mitigation plan. Alsup said it appears under the plan that PG&E would take more than 10 years to clear potentially dangerous vegetation where the fire threat is high. PG&E spokesman James Noonan did not immediately respond to an email seeking comment. Alsup is overseeing a criminal conviction against PG&E stemming from a deadly 2010 gas line explosion in the San Francisco Bay Area.
