Because of the concentration of living circles in Taiwan or the inconvenience of public transportation in remote areas in the past, locomotives, with unique features such as mobility, convenience, and ease of parking, have become the means of transport that ordinary people in Taiwan depend. Besides, the rapid development of industry and commerce has led to quick growth registrations. In particular, Chiayi City has both of the above characteristics and the characteristics of a small and heavy population, bringing Chiayi City to rank second among all counties in Taiwan in terms of the number of locomotives. Except for the positive control by the central competent authority, currently, Chiayi City has set up 44 locomotive exhaust inspection stations to provide people with the service of the regular annual inspection of locomotives. These locomotive exhaust inspection stations provide good inspection services and quality. They will also control the unscheduled inspection of locomotives in this city through checks, notices, and publicity to implement and promote a regular exhaust inspection and maintenance system. Chiayi City has also become a pioneer in the country, with the Environmental Protection Bureau being the main body of the city's locomotive exhaust regular inspection station. And it is the first to pass the international certification of the TAF inspection agency. As of December 15th, the implementation progress of the project and the progress of each quantitative target are as follows. Non-compliance locomotive inspection control is as follows: non-compliance locomotive inspections were 4,911 vehicles, and the progress achievement rate was 122.8%. We conducted eight roadside locomotive stop inspections, stopped, and inspected 1,260 locomotives, and 93 locomotives were unqualified after inspection. The unqualified rate was 7.4%, and the progress achievement rate was 105%. For mobile license plate recognition, we notified 6,819 locomotives, and 5,724 replied, with a reply rate of 83.9% and a progress achievement rate of 113.7%. In the traditional market, we notified 5,734 locomotives of non-scheduled inspection for fixed license plate recognition, and 5,237 locomotives replied, with a reply rate of 91.3% and a progress achievement rate of 95.8%. Besides, we sent 127,232 pieces of regular inspection notice postcards and returned 2,592pieces, and the return rate was 2.04%. We have adopted the on-site locomotive secret inspection operation for the locomotive inspection station in the jurisdiction to improve the inspection quality of the locomotive inspection station and to check the problems that occurred at the inspection station. Apply on-site locomotive inspection operations to investigate various deficiencies and improvements of shortcomings in inspection stations to check whether there are improper or forced repairs or arbitrary increases in repair costs and other violations. Through this actual locomotive inspection operation, we have improved the inspection station's implementation of quality assurance and quality control in various tasks such as inspection process and inspection quality. The credibility of inspection data has also improved. We have secretly checked locomotive inspection stations sixty-two times. And six of the stations have violated the relevant operating regulations of the "Measures for the establishment and management of inspection stations for air pollutants emitted by locomotives" based on the severity of the circumstances. The Environmental Protection Agency of the Executive Yuan issued to designate the East (including Gonghe) Market of Chiayi City as an air quality maintenance zone following the "Operation Instructions for the Formulation and Review of Mobile Pollution Source Control Measures in Air Quality Maintenance Zones." The relevant plan was submitted to the Administrative Environmental Protection Agency on May 2, 2022.It was approved by the Environmental Protection Administration as an air quality maintenance area on September 19, 2022; on September 30, 2022, the city announced that the East (including the Gonghe) market was an air quality maintenance area, and it will be officially implemented on January 1, 2023. The objects of control are the two-stroke engine locomotives and the fuel locomotives that have been out of the factory for five years, and those who have not completed the latest regular exhaust inspection within the time limit. To the East of the control area (including Gonghe), the inner perimeter of the market surrounding the market, excluding surrounding roads (Heping Road, Wufeng North Road, Minzu Road, Guanghua Road, Gongming Road, etc.). On January 14, 2022, the Environmental Protection Agency of the Executive Yuan announced the "incentive measures for greenhouse gas reduction by replacing old locomotives with electric locomotives." They have given subsidies to people who eliminate old locomotives or replace old locomotives with electric locomotives since 2022. Chiayi City has eliminated 4,636 old locomotives from January to December 15 in 2022, reaching 54.68% of the annual target of 8,479 approved by the environmental protection agency. It is estimated to reduce pollution emissions by pm101.0718 MT/year, pm2.50.8148 MT/year, nox4.4071 MT/year, nmhc21.3221MT/year, and co 56.7485 MT/year.
