A Russian mining giant, which is already in a dispute with authorities over a fuel spill in the Arctic earlier this year, has suffered a leak in a pipeline.

The latest accident, at the Norilsktransgaz unit, happened during the transfer of aviation fuel and lasted about 15 minutes, the company said. The spill doesn’t pose a threat to the health of people living in the area, Nornickel said. The fuel reached an unnamed lake that is not used as a source of drinking water and was localized, Tass reported, citing the local village administration.
