Hugh Pickens DOT Com writes: Mica Rosenberg reports at Reuters that major oil companies including Chevron, Exxon, ConocoPhillips, Phillips 66, and Sunoco got paid twice for dealing with leaks from underground fuel storage tanks — once from government funds and again, secretly, from insurance companies. Court documents show many of the cases and settlement agreements follow a similar pattern, accusing the oil companies of "double-dipping" by collecting both special state funds and insurance money for the same tank cleanups. Some states say any insurance payouts should have gone to them since they covered the cost of the work. "It appears this was a really common practice and it's very disconcerting," says Colorado Attorney General John Suthers. "Basically the companies were defrauding the state." Approximately 40 states and the District of Columbia have special funds to cover the costs of removing and replacing the old tanks, excavating tainted dirt and pumping out dirty groundwater. Since 1988, there have been more than half a million leaky tanks reported across the country. Nearly 80,000 spills still are waiting to be cleaned up. The lawsuits against the oil companies allege fraud or other civil, not criminal, claims, which have a lower burden of proof and do not lead to jail time. Companies are largely cooperating to forge settlement deals and were interested in partnering with the states to clean up the legacy of petroleum leaks. For example Phillips 66 paid Utah $2 million to resolve allegations that the oil company defrauded a state fund to the tune of $25 million for cleanups associated with leaking underground tanks. Phillips sued myriad insurers over coverage for contamination arising from leaking tanks around the country and Phillips 66 wound up collecting $286 million from its insurers to resolve these disputes, but it never divulged any of this to Utah officials, the suit alleged. "When I first saw these cases, I thought this is kind of incredible," says New Mexico assistant attorney general Seth Cohen, who handled the lawsuit for the state. "The oil companies have, in effect, profited off polluting."
