摘要	The county's annual average Air Quality Index (AQI) decreased from 45.4 to 38.2 between 107 (2018) and 112 (2023), showing an overall improvement in air quality. Statistical analysis indicated that the major pollutants in recent years were O3-8hr and PM2.5. In 112, the annual average PM2.5 was 8.6 μg/m3, about 15% higher than the 7.5 μg/m3 average in 111 (2022), mainly due to the impact of transboundary dust storms on multiple days in April and May, causing consistent increases in PM10 and PM2.5 levels across Taiwan. As for O3-8hr, it was 53.2 ppb, a 2.2% decrease from 54.4 ppb in the same period of 111. Assistance was provided to the Environmental Protection Bureau to achieve good performance in the "112 Annual Air Quality Maintenance and Improvement Work Performance Evaluation" conducted by the Environmental Protection Administration, and to complete the submission of all designated data required by the EPA according to the schedule. Assistance was provided to track the implementation results of various control measures under Yilan County's Air Pollution Control Plan (109-112). The amount of pollutant reduction achieved and the current air quality status from 109 to 112 all met the targets set by the Control Plan. As required by Article 7 of the Air Pollution Control Act, the EPA has proposed the "Air Pollution Control Program (113-116)." This project preliminarily consolidated the air pollution control strategies proposed by various plans and integrated the implementation of relevant inter-bureau efforts to assist the Environmental Protection Bureau in formulating the "Yilan County Air Pollution Control Plan (113-116) (Draft)." In coordination with the EPA, this project assisted the Environmental Protection Bureau in selecting 33 public and private premises from the county's controlled stationary pollution sources to report and review their air quality deterioration prevention plans. Negotiations were held with each facility to implement contingency measures earlier than required by law when the AQI reaches 100. Additionally, relevant departments were consulted to formulate various contingency control measures, which were incorporated into the "Yilan County Regional Air Quality Deterioration Prevention Measures." After confirmation by the Environmental Protection Bureau, these measures were announced and implemented by the Yilan County Government on March 2, 112. Regarding mercury pollution control in cement plants, this project completed a mercury distribution survey at 4 cement plants under its jurisdiction in 112. The survey results from 4 stacks this year mostly met the EPA's preliminary planned future mercury control standard of 50 μg/Nm³. Furthermore, the cement grinding process leads to mercury accumulation in the process. According to literature, accumulated mercury is released in large amounts within a few hours after the raw mill stops grinding. Based on this, cement plants were consulted to cooperate in conducting mercury testing in the ducts after mill stoppages. Summarizing this year's survey results, a pollution reduction consultation meeting was held in December, requesting operators to implement source management for high-mercury materials, self-evaluate and set mercury acceptance standards, and regularly test materials and ducts to monitor overall distribution changes. For the odor pollution issue in the Longde Industrial Park, OP-FTIR monitoring was performed at PM2.5 sensor hotspots in the park. After correlating with wind directions, CC-FTIR was used in 111 and 112 to survey the emission ducts of specific operators. Based on the survey results, an air pollution improvement consultation meeting was convened to discuss with operators whose duct emissions required improvement to adjust their processes accordingly and submit self-management plans to the Environmental Protection Bureau for reference. Moreover, in 105, this project assisted the Environmental Protection Bureau in conducting source investigations in response to odor complaints from residents of Dongshan Township. The operator was guided to install a regenerative thermal oxidizer (RTO) in 107. This year, CC-FTIR simultaneous sampling and GC-MS were used to analyze the pollution fingerprint and understand the current emission status. In accordance with the EPA's evaluation guidelines, this project commissioned an EPA-accredited testing company to complete monitoring of hazardous air pollutants in industrial areas and assisted the EPA in establishing a national background database for hazardous air pollutant emissions.
