Main tasks of this project include a review of the modified particulate pollutants, sulfur oxides and nitrogen oxides emissions standards, a review of the amendments to the hazardous air pollutants emission standards for different industries, and an assessment to the impact of fine suspended particles(PM2.5) emission to the atmosphere.
In order to improve the PM10 and ozone air quality, emission reduction form stationary sources is needed. The emission standards should be tightened as the control techniques improve. In response to the EPA PM2.5 control strategies and the energy conservation requirements of the Bureau of Energy, emissions standards of particulates, sulfur oxides and nitrogen oxides were reviewed and revised. Emission standards for eleven industries were reviewed, and four were prioritized in implementation. Statutory procedures for the sintering plant emission standard were completed for the upcoming announcement. The Electric Arc Furnace(EAF) emission standard draft has been discussed with the industry. The draft of the emission standards for power generation facilities and other stationary source have been submitted for professional review. The estimated reduction of particulate pollutants was 3,978 tonnes per year, sulfur oxides was 11,410 tons per year, nitrogen oxides was 31,642 tonnes per year.
Hazardous Air Pollutant standards for different industries had referenced the emission standards in the United States, China and other countries. The mercury emission standard for coal-fired power plant was proposed to be 0.01 mg/Nm3. The feasibility of including the solar cell industry into the existing semiconductor standard was also discussed.
The control strategy was emphasized on tightening the emission standards of stationary sources, reduction of fuel sulfur content, and other mobile source control measures. Research data showed that PM2.5 come from raffic source and street dust at the northern part of Taiwan, and from street dust and mainly sulfates at the southern part of Taiwan. In order to effectively improve PM2.5 air quality, mobile source emission reduction is needed at the northern part of Taiwan, stationary source emission reduction is needed at the sorthern part of Taiwan, and fugitive source emission reduction is needed at all parts of Taiwan.
