| Summary: | air quality modeling system has been developed to assess the impact of three different emission scenarios on air quality for the years 2010 and 2040. Results have been aggregated over nine characteristic episodes, representing 69 days, to find the expected response of seasonal ozone, annual average PM2.5 and annual average wet and dry deposition. These levels provide the basis for SAMI's regional effects modeling assessment. It was found that ozone can be reduced with nitrogen oxide (NOx) controls. Sulfate aerosols and sulfur deposition decrease significantly in the Class I areas in response to sulfur dioxide (SO2) emission controls. However, an increase in nitrate aerosol levels may result due to an increase in free ammonia becoming available in response to reductions in SO2 and increases in NH3 emissions. Also, changes in total nitrogen deposition were minimal, except when ammonia emissions are controlled. |
