The summary of the results from the work in this year are as follows:
I. Title: 2013 Taichung City streets dust washing plan.
II. Implementation schedule: Since April 21, 2012 to January 31, 2013.
III. Completion of the work content progress:
(I) Execution behavior of street washing since April 21, 2012 to January 31, 2013, accumulated execution of street washing 116,824.2 kilometers, cumulative rate reached 100%.
(II) Reduction assessment: The total length of the street washing are 116,824.2 km, according the Environmental Protection Agency’s (EPA) reduction formula (reductions = length × reduction coefficient street washing) estimate, TSP can be reduced to 1612.2 tones, and PM10 can be reduced to 303.7 tones.
(III) Performance Evaluation:
i. Street dust survey analysis: For city road width which above 15 meters do the street dust load survey jobs, the current detection job has completed a total of 225 points times. The total street dust load of the planned inspection of the road from May to October was reduced from 11.55 g/m2 to 2.18 g/m2, improvement rate was 81.1%; dust particle diameter between 74 – 297 μm has reduced from 3.13g/m2 to 2.18 g/m2, improvement rate was 30.4%, May, August to October street dust load a gradual downward trend means that street washing could improve street granular material effect on behalf of street washing operations.
ii. Water quality analysis of the intake point operations: 90 points intake point of water quality testing has been completed, test items including the concentration of suspended solids and E. coli.
(IV) Road census: Until the end of January, 2013, the road census statistics has completed a total of 2,263.2 km of road survey work. Average accounted for 57.7% of A-class roads, 39.9% of B-class roads, and 2.5% of C-class rods.
(V) Street washing checking: Execute 20 hours a week with 3G images and GPS checking, web survey jobs of the road is now completed more than 800 hours accumulated to check the total length of more than 16,000 km.
(VI) Street washing demonstration to promote the advocacy conference: completed on July 31, participants includes sand and gravel industry, construction industry and Taichung City District clean team, total number more than 90 people.
(VII) Street cleaning and washing network quiz and activities: it has took place on September 24 to October 24, the statistical number of participants for a total of 1,654 people, and 1,180 people got full marks on the test.
(VIII) Aggregate compile district clean team of street washing vehicles operating amount of work: Statistics Daya district, Fengyuan district and Longjing District clean team, street vehicles perform monthly amount of work were running mileage 13,197 km, TSP has total reductions of 182 metric tons, and PM10 has total reduction of 34 metric tons; Particulate matter of the removal of the street has significantly improved.
(IX) Pollution prevention plan: 2013 annual pollution prevention book set goals for a total of 320 tones of PM10 of this year, and statistics this year, Taichung City region’s street cleaning and washing job execution kilometers has total completed 164,239 kilometers of PM10 reductions of 427 tones, reached a rate of 133%; had significant improvement of the particulate matter in Taichung City air quality.
(X) The number of people to petition: total of 22 petitions in this project, decrease 45.5% compared with last year, two factors mainly for the people on the street washing purposes and practices do not understand the cause, such as the weather is too hot to sprinkle water, help street trees watering, causing slippery floor and other factors.
(XI) Innovative practices (modification carbon reduction equipment and noise reduction equipment): the noise value improvement rate up to 12.9% to 17.3%, and reduced 1,564 liters of petrol. Carbon dioxide emissions can be reduced by 3.4tones, and it will significantly help in the improvement of air quality in Taichung City.
