The EPA has approved Arkansas's official plan to reduce regional haze—the visible air pollution that reduces how far you can see across landscapes—for the period from now through the next regulatory cycle. This approval means Arkansas must follow specific steps to cut emissions from power plants and industrial sources that contribute to haze. The plan does not directly affect New Jersey, which has its own separate haze-reduction requirements.
