In order to reduce the fugitive dust quantity and to maintain the hygienic of the city street, the Environmental Protection Department of Chiayi City (EPD) applied for a subsidy from the Environmental Protection Administration (EPA) to implement the Street Fugitive Dust Improvement Plan to improve the street environment and the air quality. The plan started on 1 1, 2004 since the Bureau executed a contract to wash the street of 12,000 kilometer in length. Until 11, 2004, a total of 15002.7 kilometer street has been processed. It has reaches the 125.02% of the planned progress. Meanwhile, the Street Wash Vehicle Management System was set up in order to monitor the street wash schedule on daily basis. A series of four Total Suspended Particulates (TSP) Testing were conducted prior to, during, and after the fugitive dust improvement processes. The results showed that the fugitive dust has been reduced with a ratio somewhere between 9.7% ~ 57.4% by street washing task. The 483 public survey samples showed that the general public felt that the air quality and the fugitive dust on the street were more acceptable than before. There are over 98% residents who support this street washing plan.
