CHEYENNE, Wyo. (AP) - The Wyoming Supreme Court heard arguments Thursday in a legal challenge that seeks to force the nation's leading coal-producing state to regulate carbon dioxide emissions.
The hearing centered on a state air permit for a $1.3 billion coal-fired power plant under construction by Basin Electric Power Cooperative in Campbell County.
Environmental and conservation groups contend the Dry Fork plant is being built with obsolete technology. They say the state should regulate CO2 because of its contribution to climate change and air pollution. The state counters that its permitting process thoroughly vetted the plant and found it to meet all state regulations.
