Cross-State Rule Will Gain Power As EPA Revises Air Regs


Jacob Hollinger said that the DC Circuit’s reinstatement of the EPA’s cross-state air pollution rule, known as CSAPR, could help the agency’s efforts to combat climate change, because “one of the anticipated effects of changing climate conditions … is that there’s going to be higher ozone levels” and the nitrogen oxide regulated by the rule “is a precursor to ozone.” Mr. Hollinger predicted that “it’s going to be easier to meet [CSAPR’s] limits than what people feared,” but said it is “ just the start of more stringent ozone and nitrogen oxide requirements in the not too distant future.”
