On June 19, 2019, EPA issued the final Affordable Clean Energy rule (ACE) – replacing the prior administration’s overreaching Clean Power Plan with a rule that restores rule of law, empowers states, and supports energy diversity. The ACE rule establishes emission guidelines for states to use when developing plans to limit carbon dioxide (CO₂) at their coal-fired electric generating units (EGUs). In this notice, EPA also repealed the CPP, and issued new implementing regulations for ACE and future rules under section 111(d).
