Section 111(d) of the Clean Air Act requires states to set emission performance standards for existing sources of designated pollutants (i.e., pollutants for which there is no national ambient air quality standard). Section 111(d) specifically directs that the process for setting such standards be similar to the State Implementation Plan process for criteria pollutants under Section 110. States must adopt plans that establish standards of performance for existing sources and submit the plans to EPA for approval.
