Emission Reduction Standards for Class 3 Control Zones Preannouncedline分享列印本頁

The Emission Reduction Standards for Existing Sources in Class 3 Air Pollution Control Zones were preannounced on 19 June 2019. The reduction standards were formulated to provide set standards for existing stationary sources of air pollution at both public and private premises within Class 3 air pollution control zones and local environmental bureaus. The reduction standards are to be followed when stationary sources implement mandatory pollution emission reduction and when local environmental bureaus implement air pollution control plans. 

Air quality in Taiwan is significantly affected by topographic traits and seasonal weather patterns. Since PM2.5 is the primary pollutant type that often does not satisfy air quality standards in Taiwan, in order to accelerate air quality improvement in Class 3 air pollution control zones, experts and scholars recommend implementing control measures based on prioritized air pollutants,. The prioritized order is: primary particulate matter (PM), nitrogen oxides (NOX), and sulfur oxides (SOX). 

The main source of primary PM comes from fugitive emissions, such as dust from barren land, stacking operations and construction sites. To carry out PM control, the EPA has formulated the Management Regulations for Facilities to Control Fugitive Dust Air Pollution from Stationary Pollution Sources and the Management Regulations for Construction Project Air Pollution Control Facilities. In addition, fuel composition standards have been devised to implement SOX source controls. As for NOX emissions that primarily come from combustion, the EPA has formulated the Boiler Air Pollutant Emission Standards which will take effect on 1 July 2020. Moreover, the reduction standards mainly target specific industries with a large amount of NOX emissions (average annual emissions exceeding 40 metric tons) and other places for reduction, such as the power industry, the cement industry, the steel industry, and waste incinerators. The above mentioned industries are required to take NOX reduction measures to meet the emission standards within five years. In the meantime, the EPA will continue to strengthen air pollution control by reviewing emission standards for different industries.  

Any public and private premises in Class 3 air pollution control zones that meet the following conditions in Table 1 shall conduct NOX reduction in accordance with the reduction standards:
1. Any public and private premises whose equipment or industry type fits the explanations listed in the table below.
2. The existing stationary pollution sources in the premises are permitted to exceed an annual NOX emission of 40 metric tons based on their operation permissions.
