“Specialists of the Ministry of Natural Resources and Ecology of the Sverdlovsk Region were involved in the inspection by the prosecutor’s office,” the department said.

Specialists will take soil samples and conduct a study to determine the cause of the oil spill.

The amount of damage to the environment will also be established.

Earlier it was reported that the emergency mode was introduced in Norilsk after a major spill of diesel fuel and a fire at TPP-3.
