Norilsk Set To Avoid $178 Million Pollution Suit RUSSIA: April 10, 2008 MOSCOW/ST PETERSBURG - Norilsk Nickel appears likely to avoid a $178 million pollution suit after the head of Russia's environment agency on Wednesday disowned a claim filed by his outspoken deputy. Rosprirodnadzor head Vladimir Kirillov told reporters his agency had not brought any suit against Norilsk, the world's largest nickel and palladium miner and the subject of rival merger proposals by Kremlin-linked billionaires.
