Groups look to protect mercury standards.
The NWF said its petition was co-signed by more than 60 environmental groups and the list was growing. The NWF said the petition is prompted by the administration s reversal last week on campaign promises to limit the amount of carbon dioxide emissions from the nation s power plants. President Bush said last week that contrary to his campaign promise such emissions would not be subject to specific limits. The Utility Air Regulatory Group last month filed a suit in the same court asking the EPA to overrule the December regulations. According to Mike Murray, a NWF scientist, Countless studies have documented that mercury emissions from US sources, including coal fired electric utilities, contaminate lakes and streams, the fish within those water bodies, and the people and wildlife who eat the fishy.
