Clean Power Plan

On June 21, 2019, the Environmental Protection Agency (EPA) repealed the Clean Power Plan, effective September 6, 2019. It has been replaced by the Affordable Clean Energy (ACE) rule, which requires states to develop plans to address greenhouse has emissions from existing coal-fired power plants. The rule, fact sheets, and other materials are available on EPA's website. Please contact Marnie.Stein@dnr.iowa.gov if you would like more information.
