Description:  The Environmental Protection Agency (EPA) is finalizing multiple actions under section 
111 of the Clean Air Act ( CAA) addressing greenhouse gas (GHG) emissions from fossil fuel -fired 
electric generating units (EGUs). First, the EPA is finalizing the repeal of the  Affordable Clean Energy 
(ACE) Rule. Second, the EPA is finalizing emission guidelines for GHG emissions from existing fossil 
fuel-fired steam generating EGUs, which include both coal -fired and oil/gas -fired steam generating 
EGUs. Third, the EPA is finalizing revisions to the New Sour ce Performance Standards (NSPS) for

  GHG emissions from new and reconstructed fossil fuel -fired stationary combustion turbine EGUs. 
Fourth, the EPA is finalizing revisions to the NSPS for GHG emissions from fossil fuel -fired steam 
generating units that unde rtake a large modification, based upon the 8 -year review required by the 
CAA. The EPA is not finalizing emission guidelines for GHG emissions from existing fossil fuel -fired 
stationary combustion turbines at this time; instead, the EPA intends to take furt her action on the 
proposed emission guidelines at a later date.  
This final rule is effective on 8 July 2024. The incorporation by reference of certain publications listed 
in the rules is approved by the Director of the Federal Register as of 8 July 2024. T he incorporation
