Amicus Brief on EPA Good Neighbor Rule

The State of Utah and others filed a lawsuit over EPA’s new Good Neighbor Rule in the U.S. Court of Appeals for the D.C. Circuit. The rule is the latest in a long line of EPA regulations effectuating the requirement that upwind States eliminate emissions that “significantly contribute” to downwind States’ inability to meet certain ambient air quality standards. We filed an amicus brief rebuting multiple arguments against the rule. Our brief explains that addressing the serious and complex spillover effects caused by air pollution was a central justification for the Clean Air Act and EPA’s regulatory impact analysis demonstrates that the rule is economically justified.
