1.Environmental load and trend
In 2012, the population of Tainan City is 1.88 million; a density of 858.5 persons /km2;population in the five municipalities is ranked fifth. There are about 8,636 plants, with the density of 3.94 plant/km2, ranking third and fourth in five-municipalities and Taiwan,respectively. 2,352 plants of 8,636 were controlled, most of them are 370 plastic manufacturing (15.7%), following by 295 gas station (12.8%), and 291 metallurgical plants
(124.%).At present the city with more the manufacturing of metal products, machinery and
equipment manufacturing and plastic products manufacturing. In the construction site, the
sites increased year by year, the construction sites reached 10,074in 2012.
The total number of vehicles is 2.047 million in Tainan city, a density of 1.09 vehicles /
person; of which about 1.443 million motorcycles and 0.51millionautomobiles, and
continues to grow up each year. In addition, the amount of diesel and gasoline and gas
station sites were increasing trend, from 2003 to 2012, the amount of gasoline and diesel
sold increased from 1,165*103 kiloliters to 1,259*103 kiloliters, the gas station increased
from 269 to 295sites.
2. Air Quality Status and Problems Analysis
The poor air quality (PSI>100) ratio of Taiwan City dropped from 7.62% in 2006 to
0.68% in 2012 to improve as much as 91%, while in 2012 the ratio of poor air quality not
only to achieve air quality objectives (2.74%, 40 station-days) and 2 years (2011, 2012)
lower than the national average, hitting the best air quality records over the years, showing
the Tainan City in recent years, the effectiveness of control measures.
Currently the trends of concentration of air pollutants is declining, in which the ozone
eighth hour average values less than four consecutive years of standards. Therefore, the
ozone has been regulated as second control area. For the other pollutant concentrations,
including daily average of 8th maximum value and yearly average of PM10 and 24 hourly
average and yearly average of PM2.5, show they are in declining trends. It is deserved to

mention that PM10 daily average of 8th maximum value is the first time below the air
quality standard (125μg/m3). The improvement rate is 28.6% for PM2.5 24 hourly average
and 18.3% for that of yearly average in 95~101. The above results show that the control
strategies are doable.
3.Analysis of Emission Inventory
The emission inventory of Taiwan City in 2010 was updated by this project according to
TEDS 8.1. The emissions of point source, area source, and line source are listed in the
following table:
TSP PM10 SOx NOx NMHC CO
Point Source (tons/year) 2,715 1,651 4,332 18,120 2,814 3,989
Area Source (tons/year) 42,655 11,975 651 3,674 36,716 4,703
Line Source(tons/year) 2,743 1,971 30 20,226 16,929 52,497
Total(tons/year) 48,113 15,665 5,013 42,020 56,459 61,189
4. Programming the Air Pollution Control Strategies
2013 Taiwan City Air Pollution Control Plan was managed and developed by this
project. The purpose is to draw up the air pollution control measure goals and developed a
short-term control strategy for 2013 to 2014. The targets include the sources of stationary,
mobile, and fugitive. Three framework of PM2.5 control strategy are planed: 1. prepreparation,
design the target and background information of PM2.5; 2. basic control
strategy, conduct the reduction of original and derivative sources of PM2.5; 3. control the
regions of hot spots., including highly emitted area (based on potentially PM2.5 emitting
sources) and strongly affected area (depended on the population density and high PM2.5
concentration area).
5. Review the effectiveness of air pollution control projects
(1) Draw up "2012 Tainan City Air pollution control project management and assessment
measures."
(2) The "Diesel Dynamometer Smoke Detect Project" got the highest score for the
evaluation results in 2012, owing to the following characteristics: 1. the planed work
was conducted on time; 2. lowly changed rate for the staffs of the project; 3. no
significant errors for the database by the examining; 4. the monthly audited AQMP and
important works are well.
(3) Review of EPA evaluation results
Tainan City got the 89.13 points by the EPA announced evaluation result in 2012,
rating excellent in the five municipalities. This shows the works of this project are
highly recognized by EPA and our examining deputies.

6. Public Satisfaction Survey
Based on the questionnaire of public satisfaction survey results in 2012:
(1) Satisfaction survey of the public: More than half of citizen (55%) in Tainan believes
that air quality has improved in 2012, and 73% of the people are satisfied for the
results.
(2) Satisfaction and ethics survey of construction site: 76% of questioned people give
good recommend for the well behavior and virtue for the staffs of EPB, and 69% of
them didn't hear any scandal and illegal behavior for the staffs of EPB. The justice,
rectitude and well image of EPB are recognized by the 78% of questioned people.
