The promotional result on the current yearly project’s various items of work spanning from June 23, 2014 (the project award date) to June 22, 2015 is as follows:
On the portion of roadway cleanliness status survey, the project has been executed monthly. During the project execution period, the roadway cleanliness roaming inspection work on 205 local roadways in 29 districts across New Taipei City, with the roaming inspection mileage totaling to 914.6 kilometers, a roaming inspection ratio at 30.49%. The survey findings reveal that from July 2014 to June 2015, although level A roadways in New Taipei City have reduced to 90.35% from 94.83%, the monthly level-A roadway ratios, however, are able to maintain at an 80% or higher; also the project has, in September and December 2014, and January and April 2015 performed 4 roadway dust capability screening work on 15 roadways in New Taipei City, and through analysis, the median street dust capacity on the 15 roadways is at 1.46g/m2, the average dirt capacity is at 0.37 g/m2, where 13 roadways classified as level-A, and 2 roadways as level-B, with level-A and level-B roadway ratios at 86.7% and 13.3%. The project has implemented the “project lateral report” on construction site pollution, gravel stockpile sites, refuse and illegal advertisement postings, which tallies to a cumulative total of 4,325 cases, with reporting improvement ratio reaching 100%.
On the portion of survey performed on New Taipei City roadway maintenance status, and various districts’ cleaning teams’ cleaning machinery/equipment and functionality, the survey reveals that the cleaning crews in various districts within the jurisdiction operate a total of 35 street sweeping vehicles, 17 street hosing vehicles, and among them, only 13 districts have full-time manpower to operate street hosing and street sweeping machinery and equipment.
The current year, three parts of an air pollutant suppressing device retrofit stainless steel sifting mesh, particle impact board and micro-mist/sprinklerequipment were added to the street sweeping vehicle’s dust collection chamber, and has also performed relevant onsite testing work, where the simulated actual roadway sweeping operating shows that it is able to improve the peripheral TSP and PM10 by approximately 35%, and is able to reduce the particle count emitted from fan blower exhaust end by approximately 44%.
The result of the New Taipei City roadway sweeping optimization proposal reveals that revamping a majority of New Taipei City’s the roadway maintenance for execution by a “government-funded private-operated project”, leaving the cleaning crews only responsible for inner city major roadways’ maintenance work can comparatively ease the cleaning crews’ environmental conservation operation’s execution pressure, and also by adequately distinguishing the maintenance responsibility between the “cleaning crews” and the “government-funded private-run project”, together with infusing sufficient roadway maintenance synergy ought to significantly contribute towards New Taipei City’s permeating dust pollution suppressing work, and New Taipei City’s roadway environment cleanliness enhancement work.
On the portion of estimating the vehicular permeating dust emissions, the estimations show that in 2014 New Taipei City’s vehicular permeating dust’s TSP emissions volume tallies to 18,190 tons, PM10 emissions volume at 3,491 tons, PM25 emissions volume at approximately 845 tons; on the portion of estimating the vehicular permeating dust volume reduction, implementing the roadway sweeping work has been evaluated to be able to cut down permeating dust by 386 tons.
