On Monday, the U.S. Supreme Court will hear argument in six consolidated challenges to the Environmental Protection Agency’s (“EPA’s”) decision to regulate emissions of greenhouse gases (“GHGs”) from stationary sources under certain provisions of the Clean Air Act (the “CAA”). The cases come from the D.C. Circuit Court of Appeals, which dismissed the challenges in 2012 on the ground that the petitioners lacked standing.

In Coalition of Battery Recyclers Association v. EPA, 2010 WL 1929879 (May 14, 2010), the D.C. Circuit recently upheld an EPA rule revising the primary and secondary National Ambient Air Quality Standards (NAAQS) for air-borne lead (Pb) pollution against challenges by industry representatives. The case arose from consolidated petitions for review under the Administrative Procedure Act filed by two industry representatives alleging that the revised standards were overprotective. The circuit panel, Judge Rogers writing, rejected the petitions, holding that the new standards were supported by substantial record evidence and were not arbitrary and capricious.
