Putin declares emergency over 20,000 ton diesel spill

A large diesel spill in the Ambarnaya River, outside the Russian city of Norilsk, on Wednesday.

Moscow (CNN)Russian President Vladimir Putin has ordered a state of emergency in the Siberian city of Norilsk, after 20,000 tons of fuel spilled into a nearby river from a power station.

An environmental group has described the damage as "catastrophic," and the concentration of contaminants in nearby waters has already exceeded permissible levels tens of thousands of times over, according to Russian environmental agency Rosprirodnadzor.
The power station's employees originally tried to contain the spill on their own and did not report the incident to emergency services for two days, head of the Ministry of Emergency Situations Evgeny Zinichev said during a Wednesday meeting chaired by Putin and shown on national television.

    "So what, we are going to learn about emergencies from social media now? Are you okay over there?" Putin said, chiding Krasnoyarsk governor, Alexander Uss and managers of the Norilsk-Taimyr Energy Company, which operates the station, for a delayed response after local authorities learned about the spill from social media.
      The Investigative Committee, Russia's top law enforcement body, said Tuesday a criminal probe had been launched into 20,000 tons of diesel fuel spilling into a Norilsk river following "unexplained decompression" of a storage tank.

      Thawing permafrost?

      Nornickel, the energy company's parent, said the foundation of the storage tank possibly sank due to thawing permafrost, highlighting the dangers increasingly warming temperatures pose to Arctic infrastructure and ecosystems, according to Russian state news agency TASS.
        "Right now we can assume... that due to abnormally mild summer temperatures recorded in the past years, permafrost could have melted and the pillars under the platform could have sank," said Nornickel chief operating officer, Sergey Dyachenko, according to the TASS news agency.
