Archived Rule Development Background
Technical Information
EPA has decided to develop emissions standards for power plants under the Clean Air Act (Section 112), consistent with the D.C. Circuit’s opinion (PDF) (18pp, 51k) on the Clean Air Mercury Rule (CAMR). Accordingly, on February 6, 2009, the Department of Justice, on behalf of EPA, asked the Supreme Court to dismiss EPA’s request (petition for certiorari) that the Court review the D.C. Circuit Court’s vacatur of the Clean Air Mercury Rule (CAMR). Read the Acting Solicitor General’s motion (PDF). (2pp, 13k)
