Air pollutants that may be emitted during the GMTC’s production process include particulate pollutants, sulfur oxides, nitrogen oxides, and volatile organic compounds. All types of air pollutants are analyzed and reported in accordance with the regulations of the competent authority to control pollutant emissions, and to understand the situation of pollutants and comply with environmental regulations and standards. For analysis of exhaust pipes, we have appointed the environmental analysis and testing organizations, approved by the Environmental Protection Administration of the Executive Yuan, to conduct an analysis and testing of exhaust pipes on a regular basis in accordance with the "Regulations of Regular Self-Analysis or by Commission and Reporting Management for Stationary Pollution Sources", and report to the competent authority in accordance with relevant regulations. In 2023, the analysis and testing results of air pollutants from exhaust pipes are in compliance with the "Stationary Pollution Source Air Pollutant Emissions Standards" announced by the Environmental Protection Administration of the Executive Yuan. For each process, filter bags are cleaned and replaced according to the content of the permit. Sampling facilities are inspected and maintained annually in accordance with regulatory requirements.
The Liuying Plant is located in Liuying Science and Technology Industrial Park and Environmental Protection Technology Park. As there is no EAF steelmaking processes among the production processes in the area as promised by Liuying industrial park's EIA, Liuying Plant has conducted its own EIA for this reason. In addition to complying with the amount of pollutants emited by its own environmental assessment, Liuying Plant is also subject to the cap of pollutants imposed by Liuying Industrial Park. For 2023, it met the commitments in the environmental impact assessment.
