On July 29, 2022, the Environmental Protection Administration of Taiwan announced the draft revision to the “Types and emission limits of the 1st batch hazardous air pollutants from fixed sources”. The current regulation only sets emission limits for 5 pollutants: Polychlorinated dibenzo-p-dioxins, cadmium and its compounds, lead and its compounds, trichloroethene, and chloroethene (vinyl chloride monomer), while the draft revision adds emission limits for 18 pollutants and strengthens the emission limit for trichloroethene from 5000ppm to 55ppm at the same time. In addition, the emission limits have also been classified into 2 categories: “emissions through emission pipes” and “illegal emissions”.
The emission limits for hazardous air pollutants
The emission limits for a total of 23 pollutants (18 pollutants are newly added) are specified in the draft, refer to the table below for details. “Illegal emission” here refers to the act of emitting waste gas through ventilation holes, etc., rather than through the prescribed emission pipes.
