“The question is under the personal control of the chairman of the Federation Council,” Klishas quoted TASS as saying.

Earlier, the speaker of the Federation Council Valentina Matviyenko instructed the relevant committees to organize an offsite meeting in Norilsk with the participation of Norilsk Nickel shareholders for a thorough examination of the situation with the oil spill.

An emergency at TPP-3, owned by Norilsk Nickel, happened on May 29.

The head of Rosprirodnadzor, Svetlana Radionova, said that the rehabilitation of the environment after a diesel spill in Norilsk, according to preliminary estimates of scientists, will take from five to ten years.
