Amendments to Classes of Air Pollution Control Zones Preannouncedline分享列印本頁
:::

According to the Air Pollution Control Act, air quality standards shall be reviewed at least once every four years. Since the EPA is revising the air quality standards, the classes of air pollution control zones for special municipalities, counties, and cities will also be reevaluated to make adjustment based on realistic needs. 


The Air Pollution Control Act divides the air quality control zones into the following three classes:
1.Class 1 control zones refer to national parks and nature conservation areas as delineated by law. 
2.Class 2 control zones refer to areas whose air quality meets air quality standards, with the exception of Class 1. 
3.Class 3 control zones refer to areas whose air quality does not meet air quality standards, with the exception of Class 1.

After reviewing the current classification of the control zones, changes have been made based on the draft amendments to the air quality standards as follows: Changhua County has been reclassified as Class 3 PM10 control zone from Class 2, Yilan and Hualien County as Class 2 PM2.5 control zones from Class 3, and Kaohsiung City and Pingtung County as Class 2 O3 control zones from Class 3.

In accordance with the new control zone classifications, Yilan, Hualien and Taitung County are now considered Class 2 PM2.5 control zones while the rest of the cities/counties remain as Class 3. Therefore, the EPA will continuously strengthen the reduction of PM2.5 and precursor emissions to achieve phased reduction goals. 

Affected by the amended air quality standards that will tighten the daily average PM10 limit value from 100g/m3 to 50g/m3, the following cities/counties will still remain as Class 3 PM10 control zones: Changhua, Yunlin, Chiayi, Pingtung and Kinmen counties, and Chiayi, Tainan and Kaohsiung cities. In the future, the EPA will focus on the emission control of fugitive dust from paved roads and construction sites and open-air burning to better improve air quality and safeguard public health.
