Understanding Clean Power Plan Compliance Paths

EPA’s Clean Power Plan, released this past Monday, offers many more options for compliance than were available in the proposed rule.

CPP Pathways

The seven main possibilities include:

  • Compliance in terms of both emission rates and mass levels,
  • Compliance at the individual electric generating unit (EGU) and for the state as a whole,
  • Uniform rate obligations for all EGUs, for all EGUs of each particular type, as well as an option for states to set different emission rate requirements by unit, and
  • Mass-based targets that include just existing units, or combine new and existing units under the same rule.

These slides describe each of these options in more detail.
