Mobile source is one of the main causes of deterioration of air quality in the metropolitan area. Black smoke from diesel vehicles is denounced. The plan is designed to improve air quality in Taipei City and to provide the public with a clean and fresh living environment by implementing the inspection control program of various diesel vehicles.
According to the vehicle information analysis data from Vehicles Supervision, the registration number of vehicles in Taipei city in 2016 is estimated at around 80,000 vehicles, of which one and two term diesel vehicles accounted for 1.5% and 5.2% respectively. In the current visual inspection are more than 40,000 vehicles, of which one and two term diesel vehicles accounted for 5.1% and 11.8% respectively. At present, regardless of the registration and visual inspection of vehicles are mainly more than three term diesel vehicles, indicating that it has been more difficult to check the emissions of smoke in Taipei city. In order to accelerate one and two term old diesel vehicle replacement, Environmental Protection Administration will promote the replacement of 10,000 vehicles which is one and two term old diesel vehicle in 2017. From the registered vehicles in Taipei city, it shows that there are about 2,346 vehicles of one and two term diesel vehicles which can be inspected by dynamometer testing. Therefore, it is proposed that Environmental Protection Bureau of Taipei City Government can suggest Environmental Protection Administration again that it can formulate and announce the periodic inspection of one and two term large diesel vehicles in accordance with article 40 of the Air Pollution Control Act. In order to achieve the goal of replacement of old vehicles to, with roadside inspection and visual inspection to increase the use of inconvenience of vehicle owners and one and two term of the old diesel vehicle subsidy program which have been conducted by Environmental Protection Administration.
According to the results of diesel vehicle exhaust opacity test, roadside inspection through blacklist and visual screening can effectively inspect higher-polluting vehicles, so the opacity failure rate of roadside inspection (76.8%) is higher than the station inspected (5.9%). As a result of the direct control effect of roadside inspection, the Environmental Protection Administration will carry out 40,000 inspections in the whole country in 2017. Therefore, it recommends that the EPA can evaluate to increase the inclusion of an equipment and manpower on roadside inspection, and continue to implement the blacklist and visual screening operations. In addition, strengthening the inspection of road of high failure rate and one and two term old diesel vehicle. Through the strengthening of inspection to accelerate replacement of old diesel vehicles.
In 2015, Environmental Protection Bureau of Taipei City Government has contracted 50 garbage trucks to install diesel particulate filters plan and garbage trucks installed diesel particulate filters have been implemented 7 times inspection. The results showed that the efficiency of the opacity removal was above 99%, indicating that the installed filter was effective. Therefore, Environmental Protection Administration will promote particulate filters certification and install diesel particulate filters on three term diesel vehicles subsidy program. After the official announcement, the assessment will be conducted through the holding of the briefing session, the issuance of press releases to make three term vehicle owners can be aware of the relevant subsidy measures. It can effectively improve the pollution situation of diesel vehicles.
In recent years, due to the Environmental Protection Administration encourages all counties and cities can promote the Clean Air Zones, Taipei city has promoted 2 Clean Air Zones, including Yangmingshan and Xinyi District Clean Air Zone. In addition, Taipei city has promoted low pollution emission demonstration zone (Xinsheng Road to Songjiang Road), and implement the relevant inspection program. After the implementation inspection program in demonstration area, the pollution of the vehicle has significantly reduced, and the proportion of five term low-pollution bus has been significantly increased. Therefore, this year (2017) Environmental Protection Bureau has announced low pollution emission demonstration areas, including 6 places, 2 station and 1 line which will be implemented in July 1st. The Environmental Protection Bureau will combine self-management label to control, and more strict standards. Vehicles in the low emission demonstration area should get A-1~A-2 label, and the vehicles which do not get an A-1 ~ A-2 label will strengthen the inspection to effectively improve the air quality in lower pollution emission demonstration areas.
Through the inspection of pollution improvement of unqualified vehicles and pre-inspection vehicle and maintenance, according to the proposed annual mileage of EPA. It has estimated that the Particulate Matter Pollution (PM10) of a project can be reduced by 63.96 tons / year, an increase of 29.18 tons / year compared with 2015. (Execute device updates from October to December 2015, resulting in a large difference.)
