Abstract In the report the EPA has assessed changes in regional visibility expected from implementation of the many provisions of the Clean Air Act Amendments of 1990. The report provides an estimate of future regional visibility conditions for the contiguous 48 United States, and used a layered approach to assessing visibility changes. A preliminary assessment was made choosing key locations and a simple emission driven air quality assessment to ascertain areas likely to see changes in the distribution of man-made visibility impairment related pollutants. This preliminary analysis pointed towards a more focused approach for the Eastern U.S., concentrating mostly on changes in sulfur dioxide emissions. For the Southwestern U.S., the mixture of pollutants is more varied and less dominated by sulfur particles.
