The California Public Utilities Commission delayed approving a $12 million settlement stemming from a wildfire that swept through Malibu Canyon in 2007 after being sparked by utility poles that fell during a wind storm. A portion of the money was to be used largely for upgrading utility poles in the canyon, which is known for howling winds during Santa Ana conditions. Commissioners balked because the settlement involved only three of five parties. Not settling were Southern California Edison and NextG Networks, noted commissioner Mark Ferron, even though the commission\u2019s Consumer Protection & Safety Division found they should bear about 75 percent of the cost of any full settlement. The division proposed a total settlement of $99.2 million covering all five parties but couldn\u2019t achieve complete agreement with the companies. The settling parties were AT&T, Sprint, and Verizon. The settlement sought to resolve an investigation of the fire, which burned 3,836 acres and destroyed 14 structures and 36 vehicles, plus damaged 19 other structures. Investigators found that the fire was started by three utility poles that came down in the high winds. The poles were jointly used by Edison and the telecommunications firms.
