Chinese state media say 14 senior oil managers will be charged and 29 others disciplined for an oil pipeline explosion in northeast China.
The July 2010 explosion near Dalian city caused China's worst known oil spill and an environmental crisis.
Xinhua News Agency says 14 people have been handed over to judicial authorities, but gave no details of possible charges.
The pipeline is owned by China National Petroleum Corp., Asia's biggest oil and gas producer by volume.
Xinhua said Thursday that 29 senior managers of China National Petroleum Corp. and affiliated companies will be subject to disciplinary action, including dismissal and demotion.
The explosion resulted from workers continuing to inject a catalyst into the pipeline after a tanker had finished unloading cargo.
