In accordance with the ITB of “2010 Tainan City Air Quality Maintenance and Management Plan” (hereinafter “Project”), the execution of each work item is summarized below:
1. Environmental Burden and Trends
Presently, the population is around 1.874 million (or 855 persons per square km) that is higher than both national and Yunlin-Chiayi-Tainan averages. The number of factories has been decreasing since 1992. Currently, there are 8,462 factories (or 3.9 factories per square km). The dominant industries include manufacturing of metal and plastic products as well as machinery. There had seen increases in the number of companies in Tainan Science Park since opening, up to 2009 after which the growth has slowed down. Currently, there are 273 companies in Tainan Science Park.
Total number of moving vehicles in Tainan City is 199 million. Motorcycle is the largest number of the moving vehicles, the secondary is the passenger car. Since 2007, the growth of Gasoline car and motorcycle has come to slowly. And oil consumption is also growth slowdown. This trend may have resulted from the rise in petroleum prices and the promotion of energy savings by the government.
There have not persistent trends in the growth of construction in the past decade; it grew significantly between 2003 and 2005, dropped in the period of 2006-2007

and gone back up in the following 2 years. At present, the number of constructions is 10 thousands. Therefore, Pollution reduction ratio is most 56% that is the highest of the ten years. It has shown the effectiveness of construction site control.
The majority of environmental odors Petition are factory and restaurant related and have been on ascent. Odor improve has been the most important work for petition cases.
2. Air Quality Trends
In 2010 was seen the lowest poor air quality ratio in 7 years. The poor air quality ratio was 2.95% in 2010. which was under the control target 3.8%. The focus on improvement of the suspended populated matter in 2010, might have contributed to that progress. The main sources that cause poor air quality are suspended particulate matter and ozone pollution.
Besides the contamination of self, suspended particulate matter and ozone pollution have mostly resulted from climate changes, meteorological conditions, External contamination.
Based on the sources of pollution in Tainan City, controlling ozone concentrations should start with line sources, followed by area and then point sources. Therefore, PM10 is most come from area source. The control strategy in Tainan City should aim at area sources, in particular the improvement in naked land.
3. Air Pollution Emission
We have updated 2009 emission inventory based on TEDS-7.0, as follows.
PM10 emission: 15,384 tons per year, originating mainly from area sources. SOX emission: 6,344 tons per year, the majority of which originated from point sources. NOX emission: 29,964 tons per year, originating mainly from line sources. NMHC emission: 62,826 tons per year, originating mainly from area sources of

industry. CO emission: 41,187 tons per year, originating mainly from line sources.
4. Reviewed and revised the city air pollution control strategies
The progress achieved of air pollution control programs in 2010 is good, besides few works didn’t reach the target, for example, year average of PM10, VOC Factory reduction counseling and the ratio of construction emissions reduction.
Between counties and cities there is a considerable gap between urban and rural areas after county merger. Consider the combined area of the larger cities and counties and Regional characteristics in different places. Based on regional characteristics, “Zoning classification for control” is the short-range air quality control strategies for 2011~2012. In addition to points source, fugitive sources and mobile sources, and increase the public feeling and low-carbon life category.
5. Characteristics of air quality management objectives and develop innovative approaches
This project had planned three features works in 2010. Include detoxification project, Control project specific groups of vehicles and Dust or aerosol contamination during high-strain Projects. The perform works had been on schedule. In 2011, the first of three major features works is Periodic inspection, Eliminate the old car with Bonus gifts. Secondary is declaration of no limits, the last is no dust project.
6. Public satisfaction survey
(1) Satisfaction of Air quality improvements
There are above of 80% people for the EPA bureau’s overall attitude and expressed satisfaction on the efficiency after county merger. And 43% of respondents felt the public compared to last year, air quality have significantly improved in 2011. With 67% of the respondents Environmental Protection Agency's overall efforts to improve air pollution feel satisfied with the results. In contrast, almost a fifth three of the people expressed dissatisfaction
(2) Satisfaction with political wind construction site

Survey results of 2011is similar with 2010. Construction site control in the political wind has shown excellent. Degree of integrity in the political wind survey is an excellent. The results have a positive image of the effect of EPA bureau.
7. Monitoring and controlling the CEMS operation and enforcing the levy of the pollution control fee of the stationary pollution source
We processed to monitor and control the CEMS normal operation in our area and to continue enforcing the levy of the pollution control fee of the stationary pollution source.
