On June 2, 2014, the U.S. Environmental Protection Agency (EPA) released the Clean Power Plan Proposed Rule under the authority of Section 111(d) of the federal Clean Air Act. This Proposed Rule would establish state-specific goals to limit greenhouse gas emissions by setting firm carbon reduction standards that each state would have to meet beginning in 2020 and accelerating through 2030. While it is unclear whether the EPA will revise its Final Rule, which is expected by July 2015, many states in the Southern Legislative Conference (SLC) of The Council of State Governments already have enacted legislation addressing the Clean Power Plan Proposed Rule and its regulations. This SLC Issue Alert provides an overview of some measures taken by state legislatures in the SLC region to address the Clean Power Plan Proposed Rule through the 2014 legislative session. This Issue Alert is not a legal analysis of Section 111(d), nor does it take a position on compliance pathways or the EPA's proposed state-specific carbon dioxide (CO2) goals.
