The project is a continuity plan. It focuses on particulate sample to establish the fingerprint system and emission inventory in Taichung city. The data bases increasing year after year. It investigates the PM2.5 for stack emission and fugitive dust (construction site, exposed area, road dust) in this year. The control strategies include fugitive dust control measures, rating system and emergency management, hot zone management, non-road diesel engines management.
According to the results of stack sampling, the FPM emission factor for coal-fired plant is 2.09 ~8.52 g/ton in Taichung coal-fired power plant. The FPM emission factor for the steel industry (arc furnace, clinker plant, coke oven, blast furnace, converter, and air heating furnace) is 0.08~2.10 g/ton. The FPM emission factor for fuel oil boiler furnace is 17.9~482 g/KL which the highest. Therefore, the future control strategies will focus on fuel oil boiler furnaces.
The rating system control strategies base on eleven PM2.5 monitoring stations in Taichung city. The priority given to control are factories which emission primary PM2.5>5 ton/year, SOx>15 ton/year, or NOx>20 ton/year. If the factories are in industrial area the priority control strategies is to promote electric vehicle and tier-1 to tier-3 diesel engines with diesel particulate filters. Otherwise, the priority control strategies is to reduce traffic source including the promotion of electric bus and forbidding two-stroke motorcycles and tier-1 to tier-3 diesel engines without diesel particulate filters.
