EPA's ACE rule for affordable clean energy: what next?

摘要

31 October 2018 saw the close of the comment period for the US EPA's proposed Affordable Clean Energy rule. This opens the way for the EPA to issue a final ACE rule, which is expected to happen in the first quarter of 2019. On 21 August, 2018, the Environmental Protection Agency (EPA) issued a proposed rule pursuant to section 111 (d) of the Clean Air Act (CAA) that would establish emission guidelines for states to develop plans to limit carbon dioxide emissions from existing fossil-fired power plants. The proposed Affordable Clean Energy (ACE) rule would replace the previous administration's 2015 Clean Power Plan (CPP), which EPA is proposing to repeal (in a separate rulemaking) on the grounds that the CPP exceeded the agency's authority under the CAA.
