In general monitoring stations, this plan analyzed the yearly variation in air quality from 2005 to 2010 and the monthly variation from January 2005 to June 2010. In 2009, the nation-wide PSI>100 was 2.87% in general monitoring stations. It was the same as in 2008, but improved as compared with the 3.69% in 2007. By the end of June 2010 the PSI>100 was 2.08%, including the case of dust storm. This plan analyzed the yearly trend of traditional air pollutants and harmful air pollutants in different monitoring stations. It also aimed at the ozone precursor matter to analyze the NMHC and NOx ratio in different air basin areas. The Annual Assessment Report of the Air Pollution Control in 2008 and 2009 had completed. Furthermore, this plan has assisted the EPA with completing four air quality monitoring reports since September 2009.
The licensed floor space for construction has the highest relation to the nation-wide poor air quality. This is an important index of environmental burden. According to the climate factor, the rainfall decreases from the north to the south. On the contrary, the sunlight increases. Therefore, it is one of the reasons for higher poor air quality from the midland to the south, especially in the fall and winter. This plan has analyzed the cause of the following cases and taken measures for the follow-up,
a) The dust spreading case of local rivers on Nov. 2, 2009.
b) The case of foreign dust storm on March 21, 2010.
c) The FPC explosion case of No.6 Naphtha Project which
caused air pollution on July 25, 2010.
To cope with the serious deterioration of PSI>200 air quality, the emergency control regulations are made in Kao-Ping air basin areas. As to the foreign dust storm, this plan has amended the draft for practical application.
This plan analyzed the information from super monitoring stations in the north and south. The yearly average of PM2.5/PM10 density is about 60%~70%. In the north, the yearly average in Sinjhuang super station is slightly lower than any other 4 super stations in the south. And the ratio in the south often changes with seasons. The density of Nitrate and Sulfate changes with seasons obviously than the OC and EC. The 24-hour density changes obviously with the rush hour traffic.
According to the analysis in the PAMS, toluene has the highest density of yearly average among the 52 VOCs species. Tai Shi station has a higher propylene density. Siaogang station has a higher ethylene density. It is presumed that these ratios are affected by the neighboring petrochemical industry. Among all the PAMS in Yun-Chia-Nan, Kao-Ping air basin areas and in the north, metropolitan stations always monitor a higher density. It indicates that the mobile sources are the great contribution. According to the top 10 species of the MIR, this plan analyzed the daily and monthly trends in each PAMS. It also analyzed the causes of poor ozone quality in different areas, according to the unusual high figures monitored in Siaogang PAMS in 2007.
To report poor air quality (PSI>100) in Kao-Ping air basin areas, this plan has cooperated with the Department of Environmental Monitoring and Information Management to provide suggestion by MMS under the automatic MMS report system. Furthermore, it continues to assist monthly cross city/county roadside inspection of diesel vehicles, monthly VOC inspection at local factories, monthly inspection of dredging rivers and monthly air and land ‘eagle inspection’ in Kao-Ping air basin areas. To estimate the reduction goal of total emissions in each city and county in 2010, the 2010 objective conference was held in Kao-Ping and Chu-Miao air basin areas to discuss the reduction of environmental burden. This plan has simulated practicing 6 ozone reduction projects and discovered that the stationary source control should be strengthened. Therefore, to break with tradition and improve ozone quality from the midland to the south, vehicles in mobile sources and the THC emission in area sources should be reduced. More resources should be added to the related reduction projects. This plan completed the examination of the ‘air pollution control project’ in each city and county in 2009. Also, it synthesized the air quality goals in each city and county from 2009 to 2011. The suggestion of amendment and the technical support of the SIP ‘integration program and result management’ and the ‘air quality improvement’ in 2010 and 2011 have completed.
To provide reference for the EPA, this plan synthesized the following information,
a) Foreign information of the process of making air quality
control strategy.
b) Strengthened air quality standard aimed at pollutants from
the US EPA and related discussion on the effect upon
human health.
c) New significant development projects of the EIA and their
influence on air pollution.
This plan referred to the nation-wide total emission burden in each air basin area and made the short-term, medium-term and long-term air quality and emission targets. To provide appropriate information for the EPA to evaluate the present and future control strategies, this plan collected the latest control strategies and made different control measures in different Situations in stationary, area, and mobile sources. In order to test the total emission burden by the photochemical assessment model and evaluate the improvement of ozone air quality in the midland air basin areas, this plan collected simulation results of significant development projects from the model support center. The ozone air quality target will be accomplished successfully in the midland air basin areas in 2016 by taking the reduction measures of Situation 3 and 4. Although significant development projects have negative influence on air quality, the air quality target in the midland air basin areas will be accomplished in 2016 as taking the reduction measures of Situation 3 and 4.
