Owing to the increasing interests and concerns regarding air pollution in public, air quality management and policies at the central government level are being implemented. Chungcheongnam-do (ChungNam) has a number of largescale facilities such as power plants, steel mills, and industrial complexes. ChungNam is the second largest region in Korea with the largest air pollutant emissions. In particular, the four cities located in the northwest of South ChungNam Province (Cheonan, Asan, Seosan, and Dangjin) have various emission sources, making them major targets for air quality management. In this study, the emission and concentration levels of air pollutants in the region were investigated, and the regional impact of power plant emission reduction was analyzed. Clean air policy support system (CAPSS) and Tele-monitoring system (TMS) data were used for the emission analysis, and the atmospheric environment annual report was used for the concentration levels in this study. In the results, emissions from CAPSS showed increasing tendency from 2013 to 2016, and decreased in 2017, but that from TMS has shown decreasing tendency since 2015. The concentration of air pollutants such as PM10, NO2, and O3 in ChungNam slightly increased or showed similar level compared to the base year. The effect of emission reduction in the power plant to the atmosphere was insignificant at less than 1 μg/m3 in the whole of ChungNam. Hence, governmental reduction effort for the emissions in a specific area such as ChungNam should be made for various fields and in various ways including adjacent area from a mid- to long-term perspective rather than intensive emissions reduction to improve atmospheric environment.
