The scope of this project includes: 1) analysis of air quality monitoring data; 2) review
of emergency response mechanism for poor air quality incidents; 3) update of environmental
background information and emission inventory; 4) review and amendment of air pollution
control strategy; 5) tracking and evaluating of all air quality implementation plans; 6)
monitoring of major emission sources and fugitive emissions; 7) management of the Clean
Air Zone; 8) promotion of Ghost Festival emission reduction policies; and 9) provide the
administrative support to the New Taipei City Environmental Protection Bureau.
Analysis of air quality data between 2014 and 2016 showed that the average occurrence
of AQI≦50 is 40%, with 2016 having the highest 48%. In the same period, the average
occurrence of AQI>100 was 12%. The descending trend in the AQI analysis indicated the
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.
Mobile emission also accounts for 33%, 68%, and 29% of PM2.5, NOx, and NMHC,
respectively. Mobile sources is the highest among the six categories of emission sources.
Within mobile sources, diesel vehicles accounts for 15% and 41% of PM2.5 and NOx emission,
which mainly comes from buses and large trucks; they should be the first to be further
regulated. As for scooters, 2-stroke scooters accounts for 2%, <1%, and 3% of PM2.5, NOx,
and NMHC emissions. In contrast 4-stroke scooters accounts for 5%, 6%, and 16% of PM2.5,
NOx, and NMHC emissions; indicating positive results in the regulation of 2-stroke scooters,
further promotion should be encouraged.
There are totally 5 stationary sources of PM2.5 emission investigation was conducted in
this project. Comparing with historical data, not much difference in FPM was discovered.
However, significant difference was observed in CPM, demonstrating the complex nature of
PM formation and differences among different industries. There are totally 6 ambient air
quality monitoring stations was completed near Tucheng and Xindian monitoring station to
calculate the regression equation for the automatic monitoring stations. Following up to the
unusual high PM2.5 concentration near Linkou and Xinzhuang monitoring stations, after
inspections and specific control project, the PM2.5 concentration is back to normal. Meanwhile,
the additional generation unit in Linkou Power Plant does not display significant effect to the
nearby monitoring stations. The high toluene concentration near the Tucheng photochemical
monitoring station indicated a major emission source in the vicinity. It is advised to
strengthen the control of nearby major emission sources.
The project has assisted the EPB to coordinate air pollution reduction initiatives among
various local offices incorporate them into the Air Pollution Control Program. Meanwhile, the
effectiveness of the reduction initiatives was modeled with the CAMx program. As for the
management of Clean Air Zone, experts were invited to review the progress of various
reduction initiatives quarterly. Reduction of incense and joss paper/ghost money during ghost
festival is promoted. Continuous monitoring was conducted near three temple, and shall serve
as a reference for further promotion of incense reduction.
