Affordable Clean Energy Rule | US EPA (original) (raw)

May 11, 2023 - EPA proposes Greenhouse Gas Standards and Guidelines for Fossil Fuel-Fired Power Plants

March 7, 2023 - EPA is extending the due date for state plans under the Affordable Clean Energy Rule until April 15, 2024. Because the ACE Rule's July 8, 2022 deadline passed while the rule was vacated by the D.C. Circuit, and because states had no reason to continue to work on their plans during the period when the ACE Rule was vacated, it is necessary to extend the deadline for state plan submittal. By extending the deadline, this action makes clear the EPA does not expect states to take immediate action to develop and submit plans under Clean Air Act section 111(d) with respect to greenhouse gas emissions from power plants at this time. This is a final rule that will be effective upon publication in the Federal Register.

Proposed Affordable Clean Energy Rule
In August 2018, EPA proposed the Affordable Clean Energy rule (ACE) to establish emission guidelines for states to develop plans to address greenhouse gas emissions from existing coal-fired electric utility generating units.

Proposed Clean Power Plan Repeal
In October 2017, EPA proposed to repeal the Clean Power Plan because it exceeded EPA's authority.
