對於都會區之浮微粒污染，車行揚塵為最主要之貢獻源，因此僅仰賴固定源之控制效果不顯著，故藉由街道清洗作業以減低懸浮微粒污染。嘉義市環境保護局為降低本市道路揚塵量及維持市區道路之整潔，使市區內空氣品質不再日益惡化，故申請環保署補助辦理嘉義市加強街道揚塵洗街計畫(以下簡稱本計畫)，希能透過街道清洗作業達到改善街道市容之整潔及提升空氣品質之目的。 本計畫自93年1月1日，本工作團隊即行洗街作業之執行，每週進度均能依原先之規劃進行，預計洗街長度為12,000公里，而截至12月共完成15002.7公里之洗街長度，累計洗街長度達成率為125.02％。 本計畫也已完成洗街車行車管理系統之建置工作，並作為每日稽查洗街路線是否正確、執行里程及車速查核之依據，洗街平均車速約為13.4km/hr，可符合環保署15km/hr以下之標準，每公里平均用水量約為1.18公噸/公里。每月亦進行洗街稽核，使嘉義市道路之缺失逐月減少。另亦完成284.5公里道路普查，達成率為100.9％，其中A級有141.6公里，B級有103.6公里，C級有39.3公里。直至第4季之複查成果，A、B、C級道路分別為233.6、41及9.9公里，改善率為35.3％。本計畫目前已配合環保局辦理洗街前、中、後TSP長時間檢測六點次。經彙整分析後，隔天與洗街前約同一時段之測值比較，削減率約介於9.7％-57.4％間，平均則約有31％之下降率。問卷調查前後期分別237及246份，結果初步顯示嘉義市民眾對空氣品質及街道揚塵之感受程度，屬尚能接受，但仍需努力改善，並約有98％民眾認為洗街有助於改善空氣品質。

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.
