The Air Pollution Control Law is the basic law for air pollution control in general. This law is under the jurisdiction of the Environmental Protection Administration. Article 20 and Article 21 of the Air Pollution Control Law stipulate the reporting of emission standards and quantities. The Air Pollution Control Law stipulates air pollution control fees in Article 16. Article 17 of the same law states that “the air pollution control fees in the preceding article shall be collected by the central competent authority, with the exception of air pollution control fees for construction projects, which shall be collected by special municipality, county or city competent authorities”. The charging rate will be determined based on the current status of air quality, pollution sources, pollutants, fuel types, and the cost of pollution control. Related laws and regulations include the “Air Pollution Control Fee Collection Regulations ” and the “Stationary Source Air Pollution Control Fee Charging Rates.

About “emission standard value “and” emission limit value

Emission standard value: The emission concentration of a regulated air pollutant that is subject to administrative penalties. In consideration of the health of the people who should be protected, it is established in principle to reduce the concentration of human exposure in the environment.

Emission limit value: The emission concentration of a regulated air pollutant that is subject to criminal penalties. Concentrations of pollutants that, under conditions of acute exposure over a short period of time, may cause life-threatening health effects or death to the public.

Penalties for Violation of Emission Limits

Article 53 of the Air Pollution Control Law: If the air pollutants emit from the emission pipes of stationary sources in public or private places violate the standard hazardous air pollutant emission limits set forth in Article 20, paragraph 2, and are sufficient to threaten the life or physical health of others, the offender shall be sentenced to a fixed term of imprisonment up to seven years and can be imposed a fine from NT$1,000,000 to NT$15,000,000 together.
