This document provides a summary of EPA’s recently proposed rule to reduce carbon pollution from existing power plants. It contains a particular focus on elements of the proposal that may be of interest to the states.

The proposed rule sets individual rate-based carbon intensity goals for each state based on a state’s mix of energy sources and opportunities to achieve reductions. EPA proposes to allow states to convert the rate-based goal established by EPA to a mass-based emissions budget, discusses a method to translate to a mass-based goal, and seeks comments on translation approaches.
EPA calculated the goals by taking into account four categories of potential emission reductions, or “building blocks,” which taken together represent the best system of emission reduction (BSER):
The proposal would require states to meet an interim goal as an average over the ten-year period from 2020 to 2029 on the way to meeting a final, more stringent goal in 2030. States can meet their goals through a flexible combination of measures, including energy efficiency and renewable energy generation, and states can choose to collaborate and develop plans on a multi-state basis, and are allowed additional time to do so.
EPA notes that states may build upon their existing programs, such as the Regional Greenhouse Gas Initiative, Colorado’s Clean Air-Clean Jobs Act, and California’s Global Warming Solutions Act, as the basis for compliance.
All states will be required to submit at least an initial plan for compliance by June 30, 2016. States that need additional time to submit a final plan may request an additional year, while states participating in a multi-state program may have an additional two years to submit either separate plans or one joint plan.
