The Environmental Management Administration of the Ministry of Environment aims to elevate the knowledge and field inspection skills of its personnel in air pollution prevention. Building upon previous project implementations, which have proven beneficial in applying scientific techniques to investigate air pollutant types and sources, there is a continued focus on enhancing experience with similar cases and utilizing diverse scientific instruments. Additionally, the goal is to improve the accuracy and understanding of pollution source characteristics within the jurisdiction, reinforcing compliance and rationality of permits for stationary pollution sources. This project unfolds through six main objectives: (1) Regional environmental management air pollution background investigation and analysis; (2) On-site inspection of pollution sources; (3) Application of scientific and technological methods; (4) Assessment of air pollutant reduction for designated air quality issues; (5) Verification of Continuous Emissions Monitoring System (CEMS) data for stationary pollution sources; and (6) Discussion and observation of inspection techniques related to the project. These efforts aim to achieve the goals of inspecting, identifying, and mitigating pollution sources, ultimately reducing emissions and enhancing on-site inspection efficiency and experience. Key outcomes of the project include: 1. Regional Environmental Management Air Pollution Background Investigation and Analysis:  Analysis of emission data from regulated factories, focusing on specified air quality issues (e.g., toluene, formaldehyde, and dioxins), revealed that the main contributions to risk potential are from toluene and dioxins. High-pollution risk zones for these pollutants were identified, and further analysis of 40 high-risk factories allowed for the prioritization of key pollution sources, optimizing inspection resource efficiency. 2. On-site Inspection of Pollution Sources:  Completion of on-site inspections for 40 high-risk factories resulted in improvement recommendations across various categories, including raw material usage reporting, process flow, control equipment, emission pipelines, water process flow, and waste management. Common improvement suggestions centered around waste management, prompting recommendations for enhanced measures such as employee training and regular monitoring. 3. Intensive Inspection of Highest-Risk factories:  Through weighted sorting based on pollution risk and severity of incidents, 10 highest-risk factories were identified and subjected to Intensive inspections. Collaboration with relevant authorities ensured a comprehensive evaluation, contributing to the overall understanding of pollution risks. 4. Assessment of Air Pollutant Reduction for Designated Air Quality Issues:  Evaluation of air pollutant reduction for 10 factories based on Intensive inspections provided insights for pollution control strategies, as outlined in Table 140. 5. Application of Scientific and Technological Methods:  Execution of 14 sessions involving various scientific and technological applications, including AI emission evaluation, CC-FTIR, OP-FTIR, 3D Lidar, Gas-Find IR, Determination of THC ＆ NMHC, PSN, gaseous organic compounds, as well as aldehydes, ketones, and dioxins in exhaust stacks. 6. Verification of CEMS Data for Stationary Pollution Sources:  Execution of 6 CEMS data verification sessions identified 18 violations of CEMS management regulations and its appendices. Recommendations were provided to factories for prompt corrective action to ensure accurate and legal monitoring data. 7. seminar of Inspection Techniques:  This project conducted 1 session of the Continuous Emissions Monitoring System (CEMS) Data Verification related to stationary pollution sources, with a total attendance of 33 participants. Additionally, 2 sessions of the Inspection Techniques seminar for Air Pollution Control facilities at stationary pollution sources were organized, with a cumulative participation of 111 individuals. This project contributes to the overall objective of enhancing the efficiency and experience of on-site inspections, reducing pollution emissions, and ensuring compliance with environmental regulations for stationary pollution sources.
