The Yellow River oil spill was an oil spill in the Yellow River in Shaanxi, China which took place due to the rupturing of a segment of Lanzhou-Zhengzhou oil pipeline on December 30, 2009. Approximately 150,000 l (40,000 US gal) of diesel oil flowed down the Wei River before finally reaching the Yellow River, the source of drinking water for millions of people, on January 4, 2010.[1][2]
Background
The Lanzhou-Zhengzhou oil pipeline project was approved in 2007 and opened for operation in March 2009. It is a part of the 2,070 km (1,290 mi)-long Lanzhou-Zhengzhou-Changsha pipeline with a capacity of transporting 15 million tons of oil per year.[3] According to China National Petroleum Corporation (CNPC), the rupture took place on December 30, 2009 due to an accident near Weinan where construction was underway by third-party workers.[2] However, the incident was not publicized until January 3, 2010.[4] The deputy director of the Yellow River Water Resources Commission called for an investigation into the accident, refuting CNPC's claim that the accident was caused by third-party construction workers.[5]
Spill control efforts
About 150,000 litres of diesel had already leaked out before the pipeline was closed by CNPC. According to Pacific Environment China's co-director Wen Bo, 700 workers were quickly mobilized by the government to control the spill as soon as its occurrence became known.[2] They dug diversion channels and built floating dams to stop the pollutant from advancing further downstream. Solidifying chemicals were also used to remove the fuel from the stream.[6] Despite these efforts, officials found traces of diesel in the Yellow River on January 4, 2010, 200 km upstream of Zhengzhou.[1] No pollution was detected downstream of Sanmenxia, although the Sanmenxia reservoir was found to contain traces of toxic diesel.[7] Sanmenxia Dam and its six hydroelectric generators were shut down to prevent the flow of pollutant further downstream.[8] On 5 January, Zhang Xun, an official of the Ministry of Environmental Protection confirmed that the spill had been contained in the Sanmenxia reservoir and was no longer a threat to the river water downstream.[9][10]
