Environment Massachusetts is seeking federal emission rules aimed at coal-fired power plants and mercury is pointing to the toxin's spoiling of fish in state waters, including local ponds and lakes and the Charles and Sudbury rivers. Environment Massachusetts reports that coal-fired plants are the largest source of mercury pollution in the country and that eating contaminated fish is the main way humans are exposed to harm.

While the state enacted similar restrictions in 2004 and has worked with other New England governments to address the problem, Environment Massachusetts says the proposed Environmental Protection Agency regulations would ensure airborne mercury doesn't blow in from other parts of the country, come down with the rain and foul inland fish that Bay Staters might eat.

Tapping the federal Clean Air Act, the EPA is expected to finalize the new rule by Dec. 16.
