A Prevention of Significant Deterioration (PSD) area is an area or region that meets or exceeds the National Ambient Air Quality Standards (NAAQS). These areas are subject to additional regulations to maintain the high air quality standards. Areas that do not meet the NAAQS are referred to as nonattainment regions, and air quality control regions (AQCRs) are simply administrative boundaries for air quality management purposes.
