Abstract 1. Untile 22 December 2004, 371 inspections have been performed as part of this project. The inspection records indicate that 27 aggregate plants and 27 concrete premixing plants are monitored by the Taichung County Environmental Protection Bureau(EPB). Most of these plants are located in Taitung City,Dawu Township and Chenggong Township. 2. Compare the percentage of paved ground in aggregate plant and concrete premixing plants, paved ground in aggregate plant is about 10~50%,and about 10~90% in concrete premixing plants. 3. The consulting services on air pollution control have been provided to 6 aggregate plants and 4 concrete premixing plants. It is estimated that a total of 170.93 metric tons of particulate emission was reduced during the last year. 4. This project also addresses the possibilities of further air emission reduction, which include the installation of air pollution control equipment and implementation of air pollution control plan. It is estimated that aggregate plants have the potential of reducing 631.88 tons and concrete premixing plants have the potential of reducing 57.11 tons. 5. Until the end of December, 13 aggregate plants are rated as Group I Plant (plants without pollution control device or effective control measures); 14 aggregate are rate as Group II Plant ( only part of pollution control measures are implemented). There are no Group III Plants in Taitung County. 6. At the beginning of this project, 15 plants carry out road cleaning on voluntary basis. The number of plants that sign up to the road cleaning program is increased to 23 at the end of this project. 7. Ambient air monitoring on TSP has been carried out at 23 aggregate plants and 3
