Furious Russian President Vladimir Putin has ordered a state of emergency after a devastating fuel spill occurred in the Arctic.
Environmentalists say it is the worst such accident to happen in the Arctic as over 20,000 tonnes of diesel burst from a fuel tank at an industrial site.
The diesel reservoir collapsed at a power station outside the northern Siberian city of Norilsk last Friday, releasing 15,000 tonnes of fuel into a river and 6,000 tonnes into the soil, according to Russiaâ€™s state environmental watchdog.
The fuel was being stored there to ensure a continuous supply to a nearby power plant in case of an interruption to gas supplies.
Putin angrily criticised the delay in a cleanup operation because the authorities werenâ€™t notified. However, Norilsk Nickel, the company that owns the collapsed fuel reservoir (through a subsidiary) insists it notified the proper agencies immediately.
Greenpeace Russia said the accident was the â€˜first accident of such a scale in the Arcticâ€™ and comparable to the Exxon Valdez disaster off the coast of Alaska in 1989.
Russiaâ€™s Investigative Committee said a power station supervisor has been detained and will be charged shortly as it conducts three probes into environmental pollution and safety violations.
The Ambarnaya River, which is affected by the spill, feeds into Lake Pyasino, a major body of water and the source of the Pyasina River that is vitally important to the entire Taimyr peninsula.
Russian fisheries agency spokesman Dmitry Klokov said restoring the polluted water system would take â€˜decadesâ€™.
â€˜The scope of this catastrophe is being underestimated,â€™ he told the TASS news agency, adding that most of the fuel had sunk to the bottom of the river and already reached the lake.
Marine rescue service has put up six oil containment booms in the Ambarnaya River to stop the diesel fuel going into the lake and was using special devices to skim off the fuel.
But the clean-up mission is being hampered by the lack of roads in the area and windy weather that has already caused blocks of ice to breach the barriers, releasing more fuel towards the lake, and forcing responders to reposition them, Malov said.
â€˜Itâ€™s swampy territory, and everything can only be delivered there on all-terrain vehicles,â€™ Malov said, predicting that the collected fuel will have to stay on site until the winter in special tanks.
Norilsk Nickel said the accident possibly occurred because the ground under the fuel reservoir subsided as the permafrost melted due to climate change.
WWF expert Alexei Knizhnikov said that while climate change does affect permafrost, the accident wouldnâ€™t have happened if the company followed the rules.
By Russian law, there should be a containment structure around any fuel reservoir that would have kept most of the spillage on site, he said.
â€˜A lot of the blame lies with the company,â€™ he added.
The difficult terrain prompted some officials to suggest the collected fuel should be burned off at the scene, but Russiaâ€™s environmental watchdog chief Svetlana Radionova on Thursday ruled this out.
