In accordance with the ITB of “2011 Tainan City Air Quality Maintenance and Management Plan” (hereinafter “Project”), its execution of each work item is summarized below:
1. Environmental Burden and Trends
(1) The population is 1.874 million people it’s the maximum of Tainan City and Chiayi County and Chiayi City and Yunlin County. It’s 5th of municipalities at Taiwan. The trend of population is decreasing since 2006. The population density is 855 person/km2.
(2) Tainan City has 8,462 factories and the density is 3.9 factories/km2.The number decreased since 2002, it’s about the industrial structure has changed and economy. The industry of Tainan City is Metal products manufacturing, machinery and equipment manufacturing and plastic products manufacturing manly.
(3) In the period of 2000 to 2009 the factory number of STSP is increase, but decreased since 2009. It is 273 factories now.
(4) The number of vehicles is 2 million. There have 1.41 million motorcycles and 480 thousand cars and 12 thousand freight vehicles and 75 thousand trucks. The number of diesel cars stopped increasing since 2007, and the growth rate of motors hasn’t decreased in 1996~2000.
(5) The number of constructive engineering increased substantially since 2003, but decreased since 2005, then increased again in 2008~2010. There are 10,134 engineering now, it’s the second high in 10 years.
(6) The number of pleading cases is factories and burning and constructive engineering manly. The trend is raising.
2. Air Quality Trends
(1) The poor air quality (PSI, Pollutants Standard Index＞100 ) ratio is 2.95% in 2010, it is lower than the target 3.74%. It’s the best in 7 years. The poor air quality ratio is 1.16% till 2011/11,it is lower than the target 2.9%. Expect to reach the goal of this year.
(2) The poor PM10 ratio decreased from 3.4% to 0.5% in 1994~2003, and between 3.3%~4.6% in 2005~2007, and decreased to 1.92% in 2010. The poor PM10 ratio is 0.75% till 2011/11. The poor ratio decrease obviously.
(3) The poor O3 ratio increased from 0.4% to 3.3% in 1994~2003, and decreased to 2.3% in 2005, 3.3% in 2006 and increased to 4.6% in 2007, and decreased to 2.0% obviously in 2008~2009, and decreased to 1.92% in 2010. The poor O3 ratio is 0.41% till 2011/11. The poor ratio decrease obviously.
3. Air Pollution Emission
The emission inventory is based on TEDS-7.1, we updated it to 2009 emission inventory.
(1)TSP emission: 40,386 tons/year
(2)PM10 emission: 15,384 tons/year
(3)SOx emission: 6,344 tons/year
(4)NOx emission: 29,964 tons/year
(5)NMHC emission: 62,826 tons/year
(6)CO emission: 41,187 tons/year
4. Air Pollution Management Strategy Review and Modification
The main pollutant of reduction pollutants is PM10 (4,921tons) and constructive engineering is the main object. The second pollutant of reduction pollutants is NMHC (928.5tons) and moving source is the main object. The main pollutant of reduction pollutant in Sox is fixed source. The main pollutant of reduction in Sox is moving source.
In addition to the fixed source, fugitive source, moving source, add 31strategies and 103 countermeasures.
5. Air Pollution Management Results Plan and Follow
(1) Draw up the method of air pollution include achieved percentage inspection and quality inspection and effect inspection, and to grade.
(2) The examination in 2011
The highest score of key plan “diesel car emission examination” is 86.01, and the highest score of non-key plan “management of PM2.5 and health risk assessment” is 87.33 till 2011/10.
6. Clean Air Zones Maintenance and Management.
Finished the inspections of 48 clean air zones inspections, and 15 clean air zones got 90 points up, the best of all is ChaoAn community at BaiHo district. Selected the top17 to annual inspection in 2011/11/30 and 12/2, and choose the top4.
7. Else Items
(1) Send staffs to help the “2011 Building Taiwan” in 2011/10/26~29.
(2) Hold the “2011 Germany-Taiwan International Conference on Low Carbon City” in 2011/11/24.
(3) Attend COP17/CMP7 at Durban, South Africa in 2011/12/1~8.
(4) Hold the Education and training in 2011/12/27.
