In mid-summer 2015, EPA is expected to issue its final Clean Power Plan regulations, which aim to reduce carbon dioxide emissions from existing fossil fuel-fired power plants under section 111(d) of the Clean Air Act. The final rule will require states to develop and submit state plans as early as mid-summer 2016, to achieve the federally prescribed state emissions goals. Because EPA is expected to grant states broad flexibility in choosing a compliance pathway to achieve required emissions performance at existing power plants, states will need to evaluate the potential policy pathways and select an approach that best meets state objectives. The paper and one-pagers aim to assist states in choosing a policy pathway for their state 111(d) plans, guiding states through the key considerations and walking through potential policy pathways.
