July 30, 2010 BEIJING — China’s worst known oil spill is dozens of times larger than the government has reported – bigger than the famous Exxon Valdez spill two decades ago – and some of the oil was dumped deliberately to avoid further disaster, an American expert said Friday. China’s government has said 1,500 tons (461,790 gallons) of oil spilled after a pipeline exploded two weeks ago near the northeastern city of Dalian, sending 100-foot- (30-meter-) high flames raging for hours near one of the country’s key strategic oil reserves. Such public estimates stopped within a few days of the spill. But Rick Steiner, a former University of Alaska marine conservation specialist, estimated 60,000 tons (18.47 million gallons) to 90,000 tons (27.70 million gallons) of oil actually spilled into the Yellow Sea. “It’s enormous. That’s at least as large as the official estimate of the Exxon Valdez disaster” in Alaska, he told The Associated Press. The size of the offshore area affected by the spill is likely more than 400 square miles (1,000 square kilometers), he added. The estimates, though rough, could complicate China’s efforts to move on from its latest environmental disaster: Dalian’s mayor already declared a “decisive victory” in the oil spill cleanup, state media reported this week. The spill has caused at least one death when a cleanup worker drowned in the sticky crude, and thousands of Dalian residents have used everything from their bare hands to chopsticks to pick the goo from the sea. Steiner, who worked on the 1989 Exxon Valdez spill, announced the China estimates after touring the oil spill area as a consultant for the environmental group Greenpeace China. “It’s habitual for governments to understate oil spills,” Steiner told a news conference. “But the severity of the discrepancy is unusual here.” … Steiner said his estimates came from the fact the oil storage tank that was destroyed had a capacity of about 90,000 tons (27.70 million gallons) and reportedly had just been filled by the tanker. He said his lower estimate of 60,000 tons (18.47 million gallons) came from the rate of oil recovery by thousands of fishing boats dispatched for the cleanup. “They’ve already collected more oil than the official estimate of the spill size,” he told The Associated Press. …
