Fact Sheet - Final Revisions to Federal Implementation Plans to Reduce Interstate Transport of Fine Particulate Matter and Ozone

EPA is finalizing technical adjustments to the final Cross‐State Air Pollution Rule (CSAPR). The revisions reflect new information with technical merit that was brought to the EPA by stakeholders from a small number of units after the final CSAPR was published. These revisions provide important technical adjustments that will enhance compliance flexibility and smooth the transition from the Clean Air Interstate Rule (CAIR) programs to the CSAPR programs. No changes were made to the core elements of the program through this action.
