This paper analyzes the air quality impacts of coal-fired power plants in the northern passageway of the West-East Power Transmission Project in China. A three-layer Lagrangian model called ATMOS was used to simulate the spatial distribution of incremental sulfur dioxide (SO{sub 2}) and coarse particulate matter (PM10) concentrations under different emission control scenarios. In 2005, the emissions from planned power plants mainly affected the air quality of Shanxi, Shaanxi, the common boundary of Inner Mongolia and Shanxi, and the area around the boundary between Inner Mongolia and Ningxia. In these areas, the annually averaged incremental SO{sub 2} and PM10 concentrations exceed 2 and 2.5 {mu}g/m{sup 3}, respectively. The maximum increases of the annually averaged SO{sub 2} and PM10 concentrations are 8.3 and 7.2 {mu}g/m{sup 3}, respectively, which occur around Hancheng city. After integrated control measures are considered, the maximum increases of annually averaged SO{sub 2} and PM10 concentrations fall to 4.9 and 4 {mu} g/m{sup 3}, respectively. In 2010, the areas affected by planned power plants are mainly North Shaanxi, North Ningxia, and Northwest Shanxi. The maximum increases of the annually averaged SO{sub 2} and PM10 concentrations are, respectively, 6.3 and 5.6 {mu}g/m{sup 3}, occurring in Northwest Shanxi, which decline to 4.4 and 4.1 {mu}g/m{sup 3} after the control measures are implemented. The results showed that the proposed power plants mainly affect the air quality of the region where the power plants are built. The impacts will be decreased greatly by implementing integrated control measures. 11 refs., 8 figs., 3 tabs.
