On 26 February 2021, the EPA promulgated the Hazardous Air Pollutant Emissions Standards for Stationary Sources, giving priority to the regulation of 22 pollutants, and setting standards for the emission channels and peripheral boundaries for seven heavy metals and 15 volatile organic compounds. It is estimated that 89% of the emissions of hazardous air pollutants (HAPs) from stationary sources across the country can be regulated.
In addition to setting HAPs emission standards for specific industries (such as solid waste incinerators, power generation, vinyl chloride manufacturing processes, etc.), it was also necessary to strengthen the control of HAPs emitted by the entire stationary pollution sources. The Hazardous Air Pollutant Emissions Standards for Stationary Sources were therefore formulated in accordance with Article 20, Paragraph 3 of the Air Pollution Control Act that was revised and promulgated in 2018. It stipulates that HAPs emission standards shall be set based on the results of health risk assessment and the feasibility of prevention technologies. By examining localized data such as the current state of industrial HAPs emissions and testing data in Taiwan, and referring to the carcinogenicity of pollutants, atmospheric concentration and testing methods, the EPA screened out priority HAPs to regulate and set standards for the emission channels and peripheral boundaries to promote the reduction of HAPs from factories across the country.
The EPA further stated that most of the pollutants that have not been included in these emission standards are still regulated by the currently effective Stationary Pollution Source Air Pollutant Emissions Standards.
