Taichung city has the highest sighting report rate of the entire country of Taiwan about motor vehicles generates excessive amounts of visible exhaust emissions (“squid vehicle” in Chinese). The category of sighting reports from civilian are 78% of Motorcycles ＆ Scooters, 20% of diesel cars and 2% of car. 95% of overall sighting reports vehicle is two-stroke motorcycle. Result to that, the wasted of fuel and high concentrations of air pollution. Based on Environmental protection administration (EPA) statistics data exhaust smog check result in 2015, it shows the average of Hydrocarbons (HC) level in two-stroke motorcycle is 17 times much, and the Carbon monoxide (CO) level is 2 times much than four- stroke motorcycles. Therefore, the process of this program is after received the civilian “squid vehicle” sighting reports, through the preliminary review and verification and other processes, bureau department will sending out the inspection check notification to those suspicion squid vehicles (motorcycle and cars) to the designated location to perform air pollutants concentration detection check. Especially focus for those repeated report vehicles petitions emissions and opacity rate greater than 50%, enforce green white smoke check on those vehicles to understand the actual situation of air pollution emissions. Those who do not meet those criteria air pollutant emissions will result an improvement completion deadline. This program execution ended in 2016 December 31th and the overall performance completion reached 98.7%, included 75 conference sessions case reviews of squid car sighting reports, 16 reward prizes given out to the sighting reporters, 755 squid vehicle cases penalize, penalty to 653 unpaid fine cases and other administrative procedures. Also a total 2,537correspondence notifications send to those high-polluting vehicles to the designated place to complete the squid car green white smoke check, 1,139 scrapped vehicles process after owner received the smog recheck notification note and decided to scrapped or those call in decided to scrapped the vehicles. Two-stroke motorcycle have been completed 1,749 scrapped vehicles in 2016. In result, a reduction of air pollutants reduce PM10 0.88 t, reduce PM2.5 0.72 t, reduce NOx 0.42 t and reduce NMHC 8.45 t.
