Leaked oil spills into Arctic lake

MOSCOW — Some of the 20,000 tons of diesel oil that leaked from a power plant has seeped into a fragile Arctic lake, the regional governor said Tuesday.

Emergency workers have laid booms to block the fuel from getting into Lake Pyasino from its tributary, the Ambarnaya River.

Krasnoyarsk region Gov. Alexander Uss voiced hope that emergency officials could prevent the spilled fuel from getting into a river fed by the lake that flows into the Kara Sea, which is part of the Arctic Ocean.

The fuel leaked when a storage tank at the plant in Norilsk collapsed. Investigators said that melting permafrost had likely caused the collapse. The plant is operated by a division of Norilsk Nickel.
