Russia blames permafrost melting for huge oil spill in the Artic

Russian prosecutors have ordered checks at “particularly dangerous installations” built on permafrost after a huge oil spill in the Arctic.

An emergency was declared after 20,000 tonnes of diesel leaked into a river when a tank at a power plant near the city of Norilsk collapsed last Friday.

Initial Russian inquiries suggest ground subsidence as the cause.




The plant is owned by a subsidiary of Norilsk Nickel, which is the world’s leading nickel and palladium producer.

Delays over reporting the collapse prompted criticism from President Vladimir Putin and the power plant’s director, Vyacheslav Starostin, has been taken into custody.

The Russian Investigative Committee has launched a criminal case over pollution and alleged negligence.



Russia’s chief prosecutor, Igor Krasnov, gave orders for regional and environmental prosecutors to conduct a “thorough check” of “particularly dangerous installations” located on “territories exposed to permafrost melting”.

The aim is to prevent a repeat of the incident at the plant near Norilsk.

A spokesman for Mr Krasnov’s department told Russian media prosecutors would assess companies’ adherence to safety laws, environmental monitoring and measures to prevent emergencies.

The effectiveness of state monitoring would also be assessed, he said.

The leaked oil drifted some 12km (7.5 miles) from the site, turning long stretches of the Ambarnaya river crimson red. The spill contaminated a 350 sq km (135 sq mile) area, state media report.

In a statement, Norilsk Nickel said the incident had been reported in a “timely and proper” way.

The state of emergency means extra forces are going to the area to assist with the clean-up operation.

The accident is believed to be the second largest in modern Russian history in terms of volume, an expert from the World Wildlife Fund, Alexei Knizhnikov, told the AFP news agency.




Permafrost is a term is used for ground that is frozen continuously for two or more years. Some 55% of Russia’s territory, predominantly Siberia, is permafrost and home to its main oil and gas fields. Arctic permafrost has been melting in exceptionally warm weather for this time of year.

A 2017 report to the Arctic Council, an international forum which includes Russia, warned that because of global warming and melting ice, foundations in permafrost regions could no longer support the loads they did as recently as the 1980s.

Greenpeace has compared the recent incident to the 1989 Exxon Valdez disaster in Alaska. Oleg Mitvol, former deputy head of Russia’s environmental watchdog Rosprirodnadzor, said there had “never been such an accident in the Arctic zone”. He said the clean-up could cost 100bn roubles (£1.2bn; $1.5bn) and take between five and 10 years. It is not the first time Norilsk Nickel has been involved in oil spillages.
