On June 18, 2014, the Environmental Protection Agency (EPA) proposed regulations (the “Clean Power Plan”) addressing carbon dioxide (CO2) emissions from existing fossil fuel-fired electric generating units. Carbon dioxide is the primary human-related greenhouse gas that contributes to climate change, and these electric generating units, as a group, account for the largest source of CO2 emissions in the United States.
The proposal would establish state-specific CO2 emission rate targets measured in pounds of CO2 emissions per megawatt-hour (MWh) of electricity generation. The targets include both a 2030 goal and an interim goal to be achieved “on average” between 2020 and 2029. States would prepare and submit to EPA implementation plans describing the state-specific activities that would achieve the emission rate targets.
Assuming the proposal becomes a final rule in June 2015, states would then have until June 30, 2016, to submit their implementation plans. However, states could request an additional year for submission of a complete plan, provided that they have taken “meaningful steps” toward completion by the 2016 deadline. Alternatively, states participating in a multistate plan would have until June 30, 2018, to submit a plan. [H/T: Full Text Reports]
