Description: The Prevention of Significant Deterioration (PSD) permitting program is a Clean Air Act permitting program for new and modified major sources of air pollution such as power plants, manufacturing facilities, and other facilities that emit air pollution. PSD applies to all pollutants that do not exceed the National Ambient Air Quality Standards (NAAQS) in an area. The NAAQS establish maximum pollution concentration levels to protect public health and welfare from harmful levels of pollutants. Pollutants covered by the NAAQS are nitrogen oxides, volatile organic compounds (which are precursors to ground-level ozone), sulfur dioxide, fine particulate, carbon monoxide, and lead. These pollutants are criteria pollutants.PSD also applies to other pollutants that do not have a NAAQS. These non-criteria pollutants are listed in EPA's regulations and include fluorides, sulfuric acid mist, hydrogen sulfide, total reduced sulfur, and certain contaminants from municipal solid waste plants. http://www.epa.gov/region9/air/permit/psd-public-part.html
