Air Pollution Control Act Article 6
Stationary pollution sources shall not be newly installed or modified within Class 1 control regions, with the exception of facilities for maintaining the livelihoods of residents within the region, facilities necessary for the operation and management of national parks, and national defence facilities.Newly installed or modified stationary pollution sources within Class 2 control regions in which pollutant emissions reach a certain scale shall be required to perform modelling and simulation for their pollutant emissions in order to verify that these emissions will not exceed allowable pollutant increase limits within the control region where the pollution source is located or within adjacent control regions where air quality might also be affected.Existing stationary pollution sources within Class 3 control regions shall reduce pollutant emissions. Newly installed or modified stationary pollution sources within Class 3 control regions in which pollutant emissions reach a certain scale shall employ best available control technology. In case of specific large pollution sources, the lowest achievable emission rate control technology shall be adopted. Pollutant emissions from newly installed or modified stationary pollution sources within Class 3 control regions shall perform modelling and simulation in order to verify that these emissions will not exceed allowable pollutant increase limits within the control region where the pollution source is located or within adjacent control regions where air quality might also be affected.The central competent authority shall determine the pollutant emissions within Class 2 and Class 3 control regions, allowable pollutant increase limits, air quality modeling and simulation standards, types and scales of specific large pollution sources within Class 3 control regions, the best available control technology, the lowest achievable emission rate control technology and the criteria for reduction of pollutants from existing stationary pollution sources.
中文原文 空氣污染防制法第6條
一級防制區內，除維繫區內住戶民生需要之設施、國家公園經營管理必要設施或國防設施外，不得新設或變更固定污染源。
二級防制區內，新設或變更之固定污染源污染物排放量達一定規模者，其污染物排放量須經模式模擬證明不超過污染源所在地之防制區及空氣品質同受影響之鄰近防制區污染物容許增量限值。
三級防制區內，既存之固定污染源應削減污染物排放量；新設或變更之固定污染源污染物排放量達一定規模者，應採用最佳可行控制技術，其屬特定大型污染源者，應採用最低可達成排放率控制技術，且新設或變更之固定污染源污染物排放量應經模式模擬證明不超過污染源所在地之防制區及空氣品質同受影響之鄰近防制區污染物容許增量限值。
二、三級防制區之污染物排放量規模、污染物容許增量限值、空氣品質模式模擬規範、三級防制區特定大型污染源之種類及規模、最佳可行控制技術、最低可達成排放率控制技術及既存固定污染源應削減污染物排放量之準則，由中央主管機關定之。
二級防制區內，新設或變更之固定污染源污染物排放量達一定規模者，其污染物排放量須經模式模擬證明不超過污染源所在地之防制區及空氣品質同受影響之鄰近防制區污染物容許增量限值。
