Russia’s Far Eastern Amur emergency ministry on Sunday reported an oil spill at an oil processing plant, but said the spill was contained.
The second stage of the Russian East Siberian – Pacific Ocean pipeline is operating as usual, the ministry added.
Pipeline monopoly Transneft and the Russian Emergency Ministry task force are tackling the crash, the ministry said, without disclosing further details.
The extent of the spill was not immediately clear.
Meanwhile, a fire broke out on the Ob River in Siberia on Saturday due to an accident on an undersea pipeline, Russian state environmental watchdog Rosprirodnadzor said.
Petrochemical producer Sibur said the fire near the town of Nizhnevartovsk in the oil-rich Yugra region was quickly located and there was no risk to local people or the environment.
The accident occurred on a pipeline carrying light hydrocarbons, he said in a statement.
Large flames could be seen from a distance spitting smoke into the night sky with snow in the foreground in footage released by the RIA news agency.
