사업장 대기유해물질의 관리 개선방안

Abstract

As hazardous air pollutants(HAPs) cause some serious health problems, stricter measures are required to minimize the adverse effect by HAPs. At the present, 25 chemicals are designated as HAPs, of which some emission standards are issued. The industries which emit the HAPs should have permission for installing and operating. But these measures are not enough to protect inhabitants from HAPs. So this study was carried out to suggest the countermeasures to reduce HAPs emission from industries. Some chemicals which show large emissions in Toxic Release Inventory of 2001∼2002 is not designated as the HAPs, so it is necessary to add these to the present HAPs. It is strongly desirable that more chemicals are designated and controlled as the HAPs. How to select the main industries to be controlled is very important when the new HAPs are issued. A methodology to choose proper industrial sources to be controlled is suggested in consideration of emission volume and number of the HAPs. As a case studies, industrial sectors to be controlled are suggested for 33-urban HAPs(USA) and chemicals designated as the HAPs and VOCs in The Air Quality Conservation Law by the methodology. It is also necessary to improve the present source management system. Introduction of Emission standards based on best available technology(BAT) and periodical permitting system is strongly recommended. For successful implementation of BAT requirement, extent of available technology and available cost is very important and has to be decided by various stakeholder. And more, regulatory standards are to be designed so that industry can have flexibility to meet regulations in cost effective way. Details are presented in Chapter 5.
