Fifteen state attorneys general filed a court petition in Washington on Thursday to block the Environmental Protection Agency's new rules to curb carbon emissions from power plants, in the first of several expected legal challenges to the Obama administration measure. States from Alabama to West Virginia that oppose the Obama administration's Clean Power Plan filed, according to Reuters, for the stay in the U.S. Court of Appeals for the D.C. Circuit and asked for a ruling by Sept. 8, one year before states need to submit compliance plans to the EPA. -- SPA 00:17 LOCAL TIME 21:17 GMT تغريد
