AUGUSTA, Maine (AP) — Maine, New Hampshire and Vermont are joining a coalition of 25 states, cities and counties in defending the Environmental Protection Agency's "Clean Power Plan" against a legal challenge.
Several states are challenging the EPA rule requiring fossil-fired power plants to cut emissions, and the coalition has filed a motion to intervene in the U.S. Court of Appeals for the District of Columbia.
Maine Attorney General Janet Mills says the region bears a burden of pollution flowing from coal-fired plants to the west. She said the pollution also contributes to mercury in fish.
More than 20 other states are fighting the EPA's rules. West Virginia Attorney General Patrick Morrisey called it "an unprecedented attack on coal."
In Colorado, Gov. John Hickenlooper asked the Colorado Supreme Court on Wednesday to rule that he, not the state's attorney general, has the final say on whether to sue the federal government.
Hickenlooper's petition comes after he complained that Attorney General Cynthia Coffman should not have joined about two dozen other states in suing the Environmental Protection Agency over new air pollution rules without his authorization.
