The Alaska Department of Environmental Conservation said neither officials of BP nor its contractor, Nabors Industries Ltd., reported spills exceeding 55 gallons each that took place July 31, 2003, and Dec. 5, 2004. The state requires oil companies to report any spill exceeding that level.
In January, workers at the scene alerted Charles Hamel, a frequent oil-industry critic, who disclosed the unreported spills on his Web site, the Journal said.
Workers had originally described the incidents as blowouts, which are more damaging than spills, but a separate investigation by the Alaska Oil and Gas Conservation Commission recently concluded they weren't large enough to qualify as blowouts.
BP officials said they didn't report the spills because those involved didn't believe they were required to do so.
