Objectives : The Environmental Pollution Facility Act was implemented to effectively reduce pollutants that could be generated in the business establishment, centering on emission facilities, from the Media Act, which had been managed in the aspect of follow-up management. Accordingly, the change in the generation of air pollutants after the integrated permit in coal-fired power plants was examined.Methods : Air pollutant emission standards were analyzed for business establishment that use coal, a solid fuel, as fuel among power plants that have completed integrated permits.Results and Discussion : The standards suggested by the Act on the Integrated Control of Pollutant-Discharging Facilities have numerically higher values than the existing Clean Air Conservation Act Standards, but there is a limit to evaluating only with simple standards because permit standards are given through emission impact analysis. As a result of a comparison through the emission impact analysis, it was found that 10 plants were given stricter permit standards for sulfur oxides and nitrogen oxides by 22% and for dust by 10% at 8 business establishment.Conclusion : The level of pollution on the surrounding location status is evaluated, and permission standards are granted. It was confirmed that the emission impact analysis method under the Act On The Integrated Control of Pollutant-Discharging Facilities can be applied as a more strictly manageable means than the existing standards under the Clean Air Conservation Act.
