The work scope of this project includes: planning of the dioxin pollution sources testing, collecting the dioxin control guidelines and emission standard for the major sources, summarization the dioxin emission standard, emission control technology of different pollution sources for the foreign countries and planning the totally control strategy and establish a dioxin emission inventory. The achievements of this project are described as below: 1.There are a total of 15 points of pollution sources testing conducted in 2004. The objectives of the testing are to evaluate the representative of alternative stack for electric arc furnace, the emission investigation of dust recycle process from electric arc furnace and the verification of the dioxin reduction achievement through guidance for major pollution sources. 2.To assist EPA to promulgates ”Dioxin Control Guidelines and Emission standards for Sinter Plant”. Starting from promulgated day, the newly installed sinter plant should meet the emission standard of 0.5 ng-TEQ/Nm3. Starting from January 1,2006, the existing sinter plant should improve to meet the emission standard of 2.0 ng-TEQ/Nm3 and improve to 1.0 ng-TEQ/Nm3 by January 1, 2008. 3.The estimation of total dioxin emission of 1999, 2001, 2002 and 2003 in Taiwan area are 243.8 g-TEQ, 206.3 g-TEQ, 299.8 g-TEQ and 241.3 g-TEQ. 4.To summarize the dioxin emission standard and the existing emission conditions of 25 countries, it was found that the dioxin emission standard for incinerator are almost promulgated for these 25 countries. For the other emission sources- electric arc furnace and sinter plant, only the Japan, Austria, Belgium and Canada had promulgated the dioxin emission standard.
