12 The Taichung Power Plant (TCPP) is the second largest thermal power plant in the 13 world and has been a highly controversial source of PM2.5 emissions. In this study, the 14 CMAQ/MM5 model was validated and used to simulate the PM2.5 levels of the 11 15 stations in central Taiwan. The Base Case with all emission sources and the Control 16 Case without TCPP emission were simulated. The difference between the two simulated 17 results determines the contribution of TCPP emission.

However, 19 outlier contribution, representing the extreme episode, could reach to 15 μg m -3 in 20 autumn. Although the maximum annual average contribution of TCPP to a single 21 station was 2.0%, the maximum daily and hourly average contribution could be as high 22  Corresponding author. Ken-Hui Chang,
