The scope of this project includes: 1) analysis of air quality monitoring data; 2) analysis and response for poor air quality incidents; 3) analysis of environmental background information and emission inventory; 4) review and amendment of air pollution control policies; 5) monitoring of major emission sources and fugitive emissions; 6) management of the Clean Air Zone; 7) promotion of Ghost Festival emission reduction policies; and 8) provide the administrative support to the New Taipei City Environmental Protection Bureau. Analysis of air quality data between 2015 and 2017 showed that the average occurrence of AQI≦50 is 44.9%, with 2016 having the highest 46.6%. In the same period, the occurrence of AQI>100 had decreased over the years, with an average of 10.5%. Comparing the air quality data from January to September 2018 to the air quality data from the past five years, the descending trend in the AQI analysis indicates a gradual improvement of air quality over the years. Our team is responsible for alerting all relevant agencies for emergency response when the AQI>100 in New Taipei City. Emergency response results and investigation reports shall be reported to the EPB. According to the EPA emission inventory (TEDS 9.0), construction and roadway fugitive dust are the main sources of PM emission, which encompass 59% and 34% of PM10 and PM2.5, respectively. Industrial emission accounts for 67% SOx emission and 34% of NMHC emission. Meanwhile, mobile emission accounts for more than 90% of CO emission. We discovered that the emission of pollutants in 2017 is more than 2016. The probable cause may be the addition of 2 generation units in Linkou Power Plant and economic recovery in several industries. In 2018, The New Taipei City Government pledged to reduce the emission of particulate matter with the amount which is equivalent to the emission a coal-fired power plant. To achieve this goal, The New Taipei City Government 40 action plans, hoping to lower the yearly average of PM2.5 to 15μg/m3. In order to understand the effect of emission source reduction on the ozone 8- hour average concentration, the simulation result of the CAMx model showed that in addition to reducing household usage of NMHC, the existing industrial pollution sources, printing industry, and catering industry also need to reduce the generation of NMHC. As for the investigation and estimation of roadway fugitive dust, our project selected 155 roads in the city limit for cleanliness inspection, totaling 608 kilometers. The inspection results show that more than 90% are Grade A roads, and only a few are Grade B roads. In the administrative support section, the project assisted with the quarterly Clean Air Zone inspection and the annual assessment briefing. For the promotion of air pollution reduction during the Ghost Festival period, we assisted in the update of the website content and the printing of promotional items. We also held two forums on environmental issues and held a symposium on the control of Northern Clean Air Zone to enhance cross-domain regulation and experience exchange.
