The central competent authority shall delineate and officially announce each class of special municipality, county and city control region based on the demands placed upon air quality by land use or air quality conditions.
The control regions in the preceding paragraph shall be divided into the following three classes.
1.Class 1 control regions: Class 1 control regions refer to such areas as national parks and nature protection and conservation areas that are delineated in accordance with the law.
2.Class 2 control regions: Class 2 control regions refer to the areas that meet air quality standards, with the exception of Class 1 control regions.
3.Class 3 control regions: Class 3 control regions refer to the areas that do not meet air quality standards, with the exception of Class 1 control regions.
The central competent authority in consultation with relevant agencies shall determine the air quality standards in the preceding paragraph and shall review them at least every four years.

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.

The central competent authority shall draw up an air pollution control scheme and shall review it every four years.
Special municipality, county and city competent authorities shall determine air pollution control plans pursuant to the preceding article and the forementioned scheme and report to the central competent authority for its approval and announcement, and shall review and amend the plans every four years.
In drawing up the air pollution control scheme mentioned in the preceding article, special municipality, county or city competent authorities shall consider the fact that air pollutants are characterized by circulation, and shall determine the scheme in consultation with the competent authorities of adjacent special municipalities, counties or cities.

The central competent authority may, based on topographical and meteorological conditions, designate single or multiple special municipalities, counties or cities between which it is possible for air pollutants to circulate,as a total quantity control zone, determine total quantity control plans, and officially announce and implement total quantity controls.
Within a total quantity control zone that meets air quality standards, newly installed or modified stationary pollution sources from 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 zone.
Within a total quantity control zone that does not meet air quality standards, an existing stationary pollution source shall apply to the special municipality, county or city competent authorities for authorization of its pollutant emissions and shall make reductions in accordance with the targets and deadlines that the central competent authority has designated based on air quality requirements. Newly installed or modified stationary pollution sources from 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. Newly installed or modified stationary pollution sources shall acquire emission quantities sufficient to offset pollutant emission increases.
Existing stationary pollution sources that, as a result of the adoption of control measures, achieve actual emission reduction greater than designated reduction may bank, offset or trade the difference after authorization by the special municipality, county or city competent authorities. However, those that fail to achieve the designated reduction targets shall acquire emission quantities sufficient to offset.
The central competent authority in consultation with relevant agencies shall determine the allowable pollutant increase limits in Paragraph 2, the scale of the pollutant emissions in Paragraphs 2 and 3, the criteria for the authorization of the pollutant emissions of existing stationary pollution sources in Paragraph 3, types and scales of newly installed or modified pollution sources, the best available control technology, the lowest achievable emission rate control technology, and the regulations for the authorization of the actual emission reduction difference for banking, offsetting or trading in the preceding paragraph.

The pollutant emission increases offset by newly installed or modified stationary pollution sources in Paragraph 3 and the emission quantities offset by existing stationary pollution sources in Paragraph 4 of the preceding article shall be obtained from the following sources and offset at the rate which is lower.
1.The actual reduction difference banked by stationary pollution sources in accordance with regulations;
2.Emission quantities obtained through trading or auction;
3.Emission quantities reduced through improvement of mobile pollution sources; and
4.Other emission quantities approved by the central competent authority.
The auction regulations shall be determined by the central competent authority if the auction in the preceding paragraph is conducted by competent authorities at all levels.

The total quantity control plans for the total quantity control zones that meet air quality standards shall include allowable pollutant increase limits, measures for avoiding deterioration of air quality, principles for the approval of newly installed or modified stationary pollution sources, operational methods, and other matters.
The total quantity control plans for the total quantity control zones that do not meet air quality standards shall include pollutant types, quantity reduction targets, quantity reduction timetables, pollutant reduction quantities and timetables that the competent authorities of each special municipality, county and city within the control zone shall be required to implement, percentage of pollutants offset in Paragraph 1 of the preceding article, principles for the approval of newly installed or modified stationary pollution sources, operational methods, and other matters.

The special municipality, county and city competent authority within total quantity control zones shall determine and amend air pollution control plans in accordance with the total quantity control plans in the preceding article.
For those air pollution control plans in the preceding paragraph that are determined for total quantity control zones that do not meet air quality standards, the special municipality, county and city competent authority shall designate the stationary pollution sources that shall be required to reduce emission quantities and reduction quantities and timetables in accordance with the regulations for pollutant reduction quantities and timetables that competent authorities shall be required to implement pursuant to the preceding article.

The central competent authority in conjunction with the Ministry of Economic Affairs shall officially report to Executive Yuan the regulations related to the total quantity control in Article 8 through the preceding article after the establishment of a checking system for pollution source emission quantities and an emissions trading system and then announce and implement the regulations on a stage-by-stage and zone-by-zone basis after the approval of the Executive Yuan.

The central competent authority should establish air quality monitoring stations and regularly publicly report the state of air quality and its original data in cities, towns, and townships where petrochemical industrial areas are located and at appropriate points selected by competent authorities at all levels.
The criteria for the air quality monitoring stations established in accordance with the preceding paragraph shall be determined by the central competent authority.

When there is a concern of a serious deterioration in air quality due to variations in meteorological conditions or other reasons, competent authorities at all levels and public and private premises shall promptly implement emergency control measures. Competent authorities at all levels shall issue air quality deterioration alerts when necessary and may prohibit or restrict the use of transportation vehicles, the emissions of air pollutants by public and private premises, and activities at government agencies and schools.
Electricity enterprises, in order to implement the aforementioned emergency control measures or cooperate with competent authorities at all levels to reduce coal-fired power generation, may adjust the types of fuels used for power generation. This adjustment may result in an increase in fuel consumption for gas-fired power generation and air pollutant emissions. The increase shall be reported to the central competent authority of the relevant area for review and approval. Once approved, the limitations on annual fuel consumption and emission quantities specified in permits issued in accordance with Paragraph 4 of Article 24 shall not apply to electricity enterprises. Those that have been reviewed and approved in accordance with the Environmental Impact Assessment Act are not subject to the restrictions on the annual permitted fuel consumption and emissions contained in the environmental impact statement or environmental impact assessment report and the review conclusions.
The increment in air pollutant emissions resulting from the adjustment in the preceding paragraph shall be lower than the reduction in air pollutant emissions achieved through the implementation of emergency control measures or the reduction of coal-fired power generation. If the adjustment is made due to the implementation of emergency control measures, the period for which the increment is approved by the central competent authority shall be limited to the duration of the emergency.
The issuance of warnings, emergency control measures and approval procedures for serious deterioration of air quality in Paragraph 1 and Paragraph 2 shall be implemented by the central competent authority in consultation with relevant agencies and submitted to the Executive Yuan for approval and announcement.
