In 2005, state and federal regulators dismissed warnings from environmental groups and local officials about the risk of catastrophic flooding below a major Northern California dam. Instead, the regulators at the time said they were confident that the hillside at the Oroville Dam that helps hold back hundreds of billions of gallons of water was stable and did not need to be reinforced with concrete. FERC, the agency that oversees the dam’s re-licensing and received the request for armoring, agreed that paving was not needed. State water resources department officials wrote in a final environmental impact report dated June 2008 that no “significant concerns” about the hillside’s stability had been raised in any government or independent review.
In FERC’s DEIS for the ACP, they also say they see no significant concerns. Hmmmm….
