In August, EPA is expected to finalize and to modify its ambitious Clean Power Plan to reduce greenhouse gas emissions from existing power plants.  Here is a Watch List of key areas for possible changes and clarification that EPA might make, after considering voluminous public comments on the Proposed Regulations, which were issued in June 2014:

  • Timelines for State Implementation. Will EPA relax the level of interim requirements for emission reductions by 2020 (or 2022, as suggested in recent press reports) and allow each state a more gradual or back-loaded schedule to meet final targets by 2030?

  • Credits for Early Action. Will EPA enable states to obtain credits or adjustments in baseline periods for early emission reduction actions that have already occurred or for acceleration of emission reductions achieved prior to 2020?

Two of the Supreme Court’s major, end-of-term decisions turn on the deference the Court gives to agency determinations of the meaning of ambiguous clauses in complex regulatory statutes, applying the familiar Chevron framework.  The Court’s less deferential applications of Chevron raise important questions about the deference courts might be expected
