Five Ways EPA's Final Clean Power Plan Rule Provides More Flexibility to States

August 6, 2015

In this high-level summary of the Clean Power Plan, the Georgetown Climate Center provides an overview of changes in EPA's approach to setting goals and explains five ways in which EPA provides states with additional flexibility under the final rule. 

The paper includes a brief description of revisions EPA made to its approach to setting the emission guidelines, establishing separate nationally uniform performance levels for fossil steam and combined-cycle natural gas plants, with rate- and mass-based goals provided to add flexibility for states.

The document highlights the following five changes that provide additional flexibility:

  • Greater interim compliance flexibility
  • Additional opportunities for interstate compliance
  • More time for states to develop and submit plans if needed
  • New opportunities for early investments as a result of EPA's new clean energy incentive program
  • A new methodology for calculating mass-based budgets more equivalent to rate-based goals

Also included in this brief is an analysis of how mass-based interim goals and 2030 goals for each state change from the proposal to the final Clean Power Plan rule.
