The United States Department of the Interior has raised concerns regarding air pollution impacts in the Great Smoky Mountains National Park (GSMNP). The formation of the Southern Appalachian Mountains Initiative (SAMI) is regional effort to understand the air quality impacts of emission sources upon the Appalachian Mountains. The Tennessee Division of Air Pollution Control (TDAPC) has recently committed additional resources for the analyses of proposals for increased emissions of air pollutants in East Tennessee. The TDAPC has planned to assess these effects by conducting an air quality modeling project. The United States Environmental Protection Agency`s (US EPA`s) Urban Airshed Model (UAM) has been used as the primary air quality model for this purpose. The purpose of this project will be to evaluate the expected impact of any major new or modified air pollution source located in Tennessee on ozone in the GSMNP. An accurate emission inventory is essential to any air quality modeling analysis. A modeling inventory has been developed by the TDAPC for the base year 1993. The modeling area includes 40 counties in East and Middle Tennessee and 42 counties in neighboring states. For the counties in Tennessee, a detailed inventory of the point sources was prepared. For the other states inside the modeling domain, the EPA`s Aerometric Information Retrieval System (AIRS)-AIRS Facility Subsystem (AFS) was used to obtain point source data, The accuracy of the AFS data for the other states was not addressed, A detailed quantitative analysis has been conducted with the emission inventory developed for Tennessee counties. The purpose of this study is to quantify the relative contributions of the emissions of Volatile Organic Compounds (VOCs) and Nitrogen Oxides (NO{sub x}) from different point, area, mobile and biogenic sources to ozone formation in the vicinity of the GSMNP.
