PM2.5 has already been classified as category A(group1) carcinogen by the World Health Organization (WHO). In order to maintain populace’s health, to tighten manage over diesel vehicles which emission PM2.5 easily is necessary. This project is to be in charge of implementing inspecting operation of diesel vehicles, to conduct final strategy against high pollution diesel vehicles. Through all kinds of controlling methods to instruct owners to improve the situation of exhaust emission for the purpose of air pollution controlling.
According to statistics, this project has accomplished all progress rates from September 12, 2016 to September 11, 2017. Including roadside inspection of 1,758 vehicles, pre-screened of 562 vehicles that were pollution dangers. Most are before June 30,1999 diesel vehicles among 223 unqualified cases. By visual determination, we have informed 3,002 vehicles that had to be inspected. After analyzed, informed vehicles were mainly in EURO 2 and the horsepower rate were low which shows that vehicles might pass the inspection through irregular ways. Initiative inspected vehicles were 20,000 in number, 4,094 vehicles have already completed the inspection (inspection rate: 20.5%), Unqualified vehicles which are initiative inspected won’t be punished under the laws of Air Pollution Control Act.
In addition to passive supervision, we also promote source management through the grading standards of self-management and districted of clean zone, to enable owners realize the situation of exhaust emission. Based on statistics, 3,224 cases were issued by the end of September 11, 2017. 1,320 city buses met the grading standards of self-management (It accounted for 85% of all vehicles). Furthermore, to tutor dealers change outmoded buses progressively. In 2016 to 2017 dealers have already scraped almost 170 outmoded buses. In regard to maintenance works that authorized the mark of self-management grading standards, through comparison of 330 cases from November 2016 until now and the numerical value are all below 0.25m-1, these results indicate that authorized maintenance works have reached a certain level.
Managing diesel vehicles needs to find out first, who needs to be controlled and the burden of pollutant emission. Also analyze growth quantity of bus, big truck and light vehicle, amount of tradition pollutants and the proportion of outmoded diesel vehicles that are actual on the road recent years. Therefore, before June 30, 1999 diesel vehicles and diesel big truck are main aims.
In view of the fact that our company has been engaged in inspection and management of diesel vehicles this year, we have been very cautious in personnel training, and have organized the four educations since the project has started. To illustrate related technologies, legislations and project’s contents to increase the professionalism of project personnel.
