Oklahoma Attorney General Scott Pruitt told a congressional committee in Washington that he will ask the U.S. Supreme Court to review the state's regional haze lawsuit against the U.S. Environmental Protection Agency.
Pruitt spoke Thursday before a U.S. House Subcommittee on Energy and Power that is overseeing EPA's proposed new greenhouse gas rules that affect electricity generation.
Pruitt contends the agency exceeded its authority when it denied Oklahoma's plan to address haze that affected visibility in state wildlife areas — but a U.S. 10th Circuit Court of Appeals three-judge panel ruled 2-1 in July in favor of the EPA. The full appeals court has rejected the state's request for a rehearing.
Oklahoma utility officials have said the new haze requirements are expected to lead to higher electric rates.
