The article reports that the U.S. Environmental Protection Agency has recently proposed three regulatory options to meet the objectives of the Clean Air Act's Prevention of Significant Deterioration (PSD) program for nitrogen oxides (NOx). The PSD program ensures that areas meeting the National Ambient Air Quality Standards maintain clean air. NOx is a precursor to the formation of ground-level ozone and fine particle pollution. At elevated levels these pollutants can have significant health effects aggravating heart and lung conditions, increasing susceptibility to respiratory illnesses and damaging lungs. In addition, these pollutants have negative environmental impacts including vegetation damage, acid deposition and visibility impairment.
