SACOG evaluates all projects included in the federal Metropolitan Transportation Plan and the Metropolitan Transportation Improvement Program to ensure consistency with air quality objectives – a process referred to as finding or determining conformity.
Since September, 2011, the Regional Planning Partnership () Project Level Conformity Group is tasked with reviewing and deciding Project of Air Quality Concern (POAQC) determinations and hot-spot analyses. The Project Level Conformity Group is open to all interested parties, with membership confirmed by the RPP. ()
