New Hampshire will join an EPA lawsuit against dirty coal-fired power plants in the Midwest, Gov. Jeanne Shaheen (D) announced earlier this week. New Hampshire officials contend that emissions from the plants, including mercury and sulfur dioxide, are blown into the Northeast where they contribute to pollution and cause acid rain. New Hampshire plants have reduced their emissions by up to 75 percent during the last five years, said Robert Varney, commissioner of the state Department of Environmental Services, but the state can’t clean up its air much more without tackling pollution from outside its borders.
