LITTLE ROCK — Arkansas Attorney General Leslie Rutledge filed a lawsuit Wednesday against the Environmental Protection Agency over changes to the agency’s regional haze rule.


The suit, filed in the Court of Appeals for the D.C. Circuit, alleges that the changes are inconsistent with the Clean Air Act. The regional haze rule requires states to have plans for limiting air pollution that reduces visibility at national parks and wilderness areas.


“Regardless of who is in the White House or leading the EPA, it is my duty to protect Arkansans from federal overreach,” Rutledge said in a statement Wednesday.


“I called on the EPA last summer to fully consider the effects these amendments would have on ratepayers. Regrettably, the EPA chose a different path, which will increase costs and drastically reduce the role state officials have in establishing Arkansas’s approach to combating regional haze,” she said


The lawsuit filed Wednesday is separate from Rutledge’s challenge to the EPA’s plan for reducing haze in Arkansas, which she filed in November. Last month, she filed a motion with the 8th Circuit Court of Appeals in St. Louis to stay the plan.


Glen Hooks, director of the Sierra Club of Arkansas, said Wednesday, “Attorney General Rutledge is doing her dead-level best to model the fiercely anti-environmental behavior of President Trump. Unfortunately, her efforts come at a steep price: dirtier air for Arkansans.”


Hooks said the Sierra Club “calls on Rutledge to sideline her efforts to derail clean air protections and, instead, stand up for the health and safety of the Arkansans she has sworn to serve.”
