Abstract
Statistics up to the end of January 2008 indicate that the number of motor vehicles registered in Tainan City reached 777,581. According to data provided by the motor vehicle service station, the number of diesel vehicles had declined from roughly 12,000 vehicles at the beginning of 2007 to 8,351 vehicles in 2008, in which 5,472 were large vehicles or trucks and 2,851 were small diesel trucks. The Environmental Protection Bureau of Tainan City began implementing the Project on Diesel Vehicle Exhaust Emission Inspection in 1999, contracting a professional consultant company for its operations. The purpose of the project was to urge diesel vehicle owners and drivers to truly understand the importance of vehicle maintenance and thus improve Tainan City’s air quality. During regular traffic stops, vehicles were selected for immediate inspections; unqualified vehicles were reported and received fines, preventing vehicles from undergoing inappropriate adjustments before inspections and bringing the most benefits from a limited number of inspections. In addition, diesel oil audits were enhanced to put an end to the use of illegal diesel oils with high sulfur content, preventing air pollution from sulfide.
After implementing the diesel vehicle smoke emission control policy for several years, the number of diesel vehicles emitting black smoke on the streets has been reduced significantly. However, having less income in poor economic times has lowered diesel vehicle owners’ willingness to spend a little more money on normal maintenance, and caused them to make abnormal adjustments to the gas pedal or limit engine speed for inspections.
Tainan City’s inspection station passed the ISO14001 certification in 2000 and has maintained good inspection quality ever since, which has strengthened public confidence in inspections. In March 2007, it was officially recognized by Taiwan Accreditation Foundation (TAF) as and accredited laboratory for inspections, and will continue to maintain its high quality to gain public approval.
Yet, the inspection station’s current inspection equipment is old, have high failure rate and are hard to maintain. In order to elevate overall inspection quality and improve hardware problems of the current inspection station, subsidies are required from the Environmental Protection Bureau to establish a new inspection station.
Nine people were allocated for the implementation of this project, in which seven had a license for operating diesel vehicle smoke emission measurement instruments and four had acquired certificates of visual determination of smoke
