Integrated environmental permission system, which was introduced to effectively manage pollutants generated by industry, assess air pollutants using discharge impact analysis and set the permissible discharge standards according to environmental characteristics. The method of setting permissible discharge standards through discharge impact analysis is a method already applied in Europe and United States. For this reason, comparing and researching the air quality assessment methods of the countries in which it is applied is considered to be helpful in deciding the direction of Korea’s integrated environmental permission system. In this study, the air quality assessment methodologies of United States, United Kingdom, Germany and Korea integrated environmental permission systems were compared. In case of United States, United Kingdom and Germany, developing and applying model and factors which were reflected the characteristics of their own countries for accurate air quality assessment. On the other hand, Korea’s integrated environmental permission system was assessed by applying the H1 guideline in the United Kingdom, TA-Luft in Germany, and AERMOD modeling in the United States. In addition, in Korea’s integrated environmental permission system, all industries and pollutants are assessed by applying the same modeling method. For this reason, it is difficult to reflect interaction factors according to industry, materials, surrounding environment. In additions, there is a limitation in that the assessment method for secondary pollutants such as ultra-fine dust (PM-2.5) or ozone generated by photochemical reactions, and the permissible discharge standards for this have not been specifically established. In order to overcome the limitations of the current integrated environmental permission system, it is judged that it is necessary to advance the pollutant assessment methods and discharge impact analysis modeling by referring to the assessment methods of abroad.
