On Tuesday morning the EPA revealed its proposed plan for replacing the Obama-era “Clean Power Plan.” The EPA says the new rule will give states more authority and create new jobs, taking the place of the “overly prescriptive and burdensome” Clean Power Plan. The new plan, titled the “Affordable Clean Energy” or “ACE” Rule, would give states broader choice in regulating power plants’ greenhouse gas emissions. By the EPA’s own admission, the proposal could lead to an additional 1,000 premature deaths per year. This statistic has led many opponents of the new plan to argue that it is unsafe and favors industry over health.

The Obama Clean Power Plan was finalized in 2015, and focused on targeting and shutting down coal-fired power plants, accounting for nearly 40% of U.S. carbon dioxide emissions. However, the rule remained on hold, pending legal challenges from several states. In October 2017, then-EPA administrator Scott Pruitt rolled back the Clean Power Plan, pursuant to President Trump’s promises to push energy use based on all resources including coal.

The EPA believes the ACE Rule will provide states with a clear list of “candidate technologies” to establish standards of performance for incorporation in state plans, update the New Source Review permitting program to encourage “efficiency improvements” at existing power plants, and give states additional flexibility in establishing their own plans.
