臺南市政府環境保護局為有效改善車行揚塵污染問題，並延續歷年施政方針，特專案辦理「109年度臺南市加強街道揚塵洗街計畫」，統計109年4月7日至110年4月6日間，本計畫規劃執行進度及達成狀況，如表一及表二所示，茲將現階段各項工作執行成果摘要說明如下： 一、本計畫執行道路洗街作業長度合計71,362.5公里，計畫進度總達成率為101.9%，總計洗街用水量為77,082.99噸，平均逐月單位長度(公里)用水量皆為1.08公噸，總平均單位用水量亦相同，均大於合約規範用水量。 二、本計畫共規劃有14處之合格放流水取水點，分別於109年5月、109年8月、109年11月及110年2月，完成4次水質檢測作業；各取水點懸浮固體(SS)濃度介於<2.5~39 mg/L之間，均符合本計畫用水規範；氫離子濃度(pH)介於6.7至8.9之間，亦均符合本計畫用水規範；溶氧量(DO)介於1.3~9.0mg/L之間，其中第2次水質檢測安平水資源中心(DO)為1.3 mg/L與官田水資源中心(DO)為2.5mg/L，此兩處水質不合格於收到局內函文暫停使用，於6/1取水複驗，檢測結果符合陸域地面丁類水質標準，pH為7.0~7.5，SS為2.5~9.4 mg/L，DO為5.8~6.8 mg/L，複驗合格於6/13開始取用。並於109年9月新增2處取水點，採樣檢測後pH為6.7~7.0，SS為<2.5mg/L，DO為4.0~6.2 mg/L，均符合陸域地面丁類水質標準。 三、進行道路髒污調查作業，共計完成道路普查分級共1,312條，合計4,406.20公里，其中A級道路共1,200條，計3,947公里(佔89.6%)；B級道路共112條，計459.2公里(佔10.4%)；且無C級道路。 四、109年度街塵檢測洗街前平均街塵介於0.3680~2.0645 g/m2，洗街後平均街塵介於0.1092~0.4823 g/m2，整體削減率為75.78%，由街塵檢測結果顯示，洗街作業前後街塵之去除效果，因各路段平均負荷量不同，在第一季去除效益整體較第二~四季低，主因洗街前道路街塵已低，能再清洗走之街塵可能有限，故第二季去除效率較高，但整體洗街作業削減率仍有75.78%以上成效。 五、彙整本市各主要道路維護權責單位洗掃長度，現階段本計畫共完成洗街作業總長度(統計至4月)達71,362.50公里、各區清潔隊合計執行洗掃作業312,999.14公里、交通部公路總局各工務段合計35,538.00公里、清管科委外掃街計畫執行掃街作業81,844.90公里、本市各工業區服務中心和企業道路認養合計執行洗掃作業27,408.06公里、營建工地道路認養合計執行39,521.73公里。總計本市推動洗掃作業總長度為572,383.33公里，詳表7.1.1-1；依據行政院環境保護署訂定之洗掃街作業對TSP削減之公式計算，推估可削減TSP達7,520.66公噸(因企業認養大多為環境清潔，對於懸浮微粒削減較為薄弱，故TSP削減量便不列入計算)。 六、計畫期間邀集農政單位、警政單位，一同辦理1場次協商會，及一同邀集代耕業者辦理3場次宣導會，分別為麻豆場、後壁場、新營場，由農業局「農機證/農機號牌辦理事宜」、警察局「農耕機具未懸掛號牌取締」及環保局「農耕機上路污染道路改善」進行宣導，共計聯合宣導80位業者、民眾參與。 七、本計畫依據109年08月28日分工協商會議決議，15區高農作公所需提出兩條示範道路，共計30條，計畫執行期間共計查獲11件次污染狀況，皆經第一次複查後改善故無進行插旗。 八、109年度問卷調查中，訪問洗街路段里長，調查中執行道路洗街作業之後，對於道路揚塵改善程度表達好以上等級佔81%；洗街車執行道路洗街作業，是否會造成您的困擾問項中表達不困擾及非常不困擾合計佔92%；並滿意洗街作業者佔81%，且100%肯定使用回收水洗街，可見計畫執行仍有其一定成效性。 九、本計畫現階段亦執行多項積極管制作業，包括：1.已完成舉辦4場次內部工作檢討會等相關會議；及2場次教育訓練；2.空品惡化緊急應變措施；3.協助局內進行宣導作業；5.配合環保署逸散污染源空氣污染物排放管制及減量計畫通報清掃作業。

(1)Execution of street flushing The total length of road washing operations in this plan is 71,362.5 kilometers, and the total project progress rate is 101.9%. The total water consumption for street washing is 77,082.99 tons. The average monthly water consumption per unit length (km) is 1.08 metric tons. The average unit water consumption is also the same, which is greater than the contractual water consumption. (2)Water quality testing The project plans a total of 14 qualified discharge water intake points. In May 2020, August 2020, November 2020 and February 2021, 4 water quality inspection operations were completed; suspended solids at each water intake point ( The concentration of SS) is between <2.5~39 mg/L, which meets the water specifications of this project; the hydrogen ion concentration (pH) is between 6.7 and 8.9, which also meets the water specifications of this project; the amount of dissolved oxygen ( DO) is between 1.3~9.0mg/L, the second water quality test Anping Water Resources Center (DO) is 1.3 mg/L and Guantian Water Resources Center (DO) is 2.5mg/L, the water quality of these two places Disqualified after receiving the letter from the bureau, it will be suspended for use, and the water will be retested on 6/1. The test result meets the land surface water quality standard, pH is 7.0~7.5, SS is 2.5~9.4 mg/L, and DO is 5.8~ 6.8 mg/L, the re-inspection was qualified and started to be taken on 6/13. Two additional water intake points were added in September 109. After sampling and testing, the pH was 6.7-7.0, the SS was <2.5 mg/L, and the DO was 4.0-6.2 mg/L, all of which met the terrestrial ground water quality standards. (3)Road dirt survey Carrying out road pollution investigation operations. A total of 1,312 road surveys were completed, totaling 4,406.20 kilometers, of which 1,200 were A-level roads, totaling 3,947 kilometers (accounting for 89.6%); and B-level roads were 112, totaling 459.2 kilometers ( (Accounting for 10.4%); and there is no C-level road. (4)Performance evaluation for the street flushing To evaluate the performance of reduction in the street flushing and establish the road emission coefficients of the city, 96 spots were selected on 16 roads and streets in the street cleaning project for street dust load testing and sample analysis before and after the flushing. Before the street flushing, The average street dust before street washing is 0.3680~2.0645 g/m2, and the average street dust after street washing is between 0.1092~0.4823 g/m2, and the overall reduction rate is 75.78%. The result of street dust testing shows that the street before and after street washing operation The dust removal effect is different in the average load of each road section. The removal efficiency in the first quarter is lower than that in the second to the four seasons. The main reason is that the street dust on the road before washing is already low and the street dust that can be cleaned and walked may be limited. The efficiency is high, but the overall reduction rate of street washing operations is still more than 75.78%. (5)Integration of city-wide street flushing and sweeping resources Consolidate the cleaning and sweeping lengths of the main road maintenance units in the city. At this stage, the total length of street cleaning operations (as of April) is 71,362.50 kilometers. The cleaning teams in all districts have performed cleaning and sweeping operations in total of 312,999.14 kilometers. A total of 35,538.00 kilometers of public works sections of the General Administration of Highways of the Ministry of Communications, 81,844.90 kilometers of street sweeping operations carried out by the outside sweeping plan of the Pigging Science and Technology Commission, a total of 27,408.06 kilometers of washing and sweeping operations carried out by the service centers and enterprise roads of the city's industrial parks, and construction site roads adopted. A total of 39,521.73 kilometers were executed. In total, the city’s total length of cleaning and sweeping operations is 572,383.33 kilometers, as shown in Table 7.1.1-1; according to the formula for reduction of TSP by street cleaning and sweeping operations set by the Environmental Protection Agency of the Executive Yuan, it is estimated that TSP can be reduced by 7,520.66 metric tons (because of Most companies adopt a clean environment, and the reduction of suspended particulates is relatively weak, so the reduction of TSP is not included in the calculation). (6)Improvement of road pollution by farming machines (A). During the planning period, the agricultural and police units will be invited to conduct a consultation meeting together, and to invite cultivators to conduct 3 publicity meetings, namely the Madou Field, Houbi Field, and Xinying Field, which are organized by the Bureau of Agriculture. The place where the agricultural machinery license/agricultural machinery license plate was issued was promoted by the police station "Agricultural machinery is not issued with a license plate" and the Environmental Protection Agency "Agricultural Machinery on the Road Polluting Road Improvement". A total of 80 operators were jointly promoted and the public participated. (B). According to the resolution of the division of labor consultation meeting on August 28, 2020, this plan required two demonstration roads in the 15 districts, totaling 30, and a total of 11 pollution cases were seized during the execution of the plan, all of which were the first After the second review, there was no flagging because of improvement. (7)Questionnaire In the 2020 year questionnaire survey, interviews with the length of the street washing section. After the road washing operation was carried out in the survey, 81% of the road dust improvement degree was well expressed and accounted for 81%; whether the street washing vehicle performed the road washing operation would cause you Among the troubled questions, 92% of them express no trouble and not trouble very much; 81% are satisfied with street washing operators, and 100% are sure to use recycled water to wash the streets. This shows that the implementation of the plan still has a certain effect. (8)Active control measures A.Emergency response measures against air quality deterioration B.Establishment of joined reporting mechanism for dirty roads C.Assistance for the bureau in campaign efforts D.Reporting for street cleaning for the control and reduction plan of Environmental Protection Administration for air pollutant emission from fugitive pollution sources.
