There are 94 factories installed at present, of which 49 are regulated for stationary sources, 31 are not regulated, 4 are temporarily suspended and 10 are in installation with a total employment of approximately 3,666.
A total of 678 factories were inspected in the Industrial District. During the inspection, abnormal or defective conditions were found 38 times, accounting for about 5.6% of the inspection, The defective rate of this year is similar to 2018, but higher than 2019. Most of the improvements have been completed after re-examination. However, Jianshin's second Factory, Fuguangxin, and Xingwei had repeated occurrences, and the improving quality also needs to be strengthened. To continuous advanced, they contacted reference units and accepted the expert's advice to improve the pollution situation.
The concentration of each pollutant is lower than the air quality standards or AQI 100 in the air quality monitoring of this year, compared with the neighboring air quality monitoring stations, the trend of concentration change is similar without any obvious situation of moving higher. However, Donghai Elementary School SO2 and NMHC in the first quarter and Yuhkang Elementary School PM10 in the fourth quarter were significantly higher. According to the monitoring results of the neighboring air quality monitoring, SO2 did not source from the Pingnan Industrial District, instead, it caused by surrounding pollution sources or human activities, and the source of NMHC might be Yiyang Company. PM10 was determined that caused by surrounding pollution sources or open burning, rather than Pingnan Industrial District.
The analytical sample average of Dioxin is 0.025 pg I-TEQ/m3 (standard deviation = 0.031, excluding PCBs) of the perimeter air and sediment this year. The average concentration of total toxicity equivalency is about 0.024 pg WHO2005-TEQ/m3 (including PCBs), which is converted with WHO2005-TEF. It is quite lower than the annual average, 0.6 pg WHO2005-TEQ/m3 of Japan's ambient air quality standard. PCBs account for about 4.4%-27.3% of the total toxicity equivalency. Comparing with the monitoring results, PCBs = 0.9%-29.4% summarized by the Environmental Protection Administration in 2019 Air Quality Monitoring Stations (The Project of Stationary Sources Emission Investigation, Environmental Monitoring and Emission Reduction Promotion Plan Targeting on Dioxin and Heavy Metals), the effect of PCBs on the total toxic equivalency of Dioxin in the air is not significant this year. However, in the first quarter, the concentration of Yuh Kang Elementary School were apparently high, which was suspected that it was caused by the days of poor air quality and the pollution sources nearby. The concentration range of this year is similar to the project of 2010-2017 and the concentration range of Pingtung air quality monitoring station in 2017. The concentration of sediment samples was 0.404-1.18 ng I-TEQ/kg, which was in line with the lower limit value of "Regulaions for Classification, Management and use of Sediment Quality Indicator and Restrictions" by the Environmental Protection Administration of Executive Yuan this year. Besides that, the concentration range was similar to the Zeng-Wen river, and there’s no abnormal occurrence.
In the inspections part, there have been completed with 3 times of PSN implemented, 2 times of Dioxin, 1 time of the verification of VOCs reduction rate, and 1 time of the 24 items of heavy metal detection. All the Detect were in compliance with the regulatory standards.
The organic function measurement of odor had been implemented 13 times, including 3 times from the perimeter, 9 times from the gas duct, and 1 time assist the odor audit inspection of the non-Pingnan Industrial Park. Among them, the flue gas odor inspection results of Lianyou Metals, Jian Shin Second Factory, Enrestec, Hwa Chient, and Cheng Song have exceeded the standard, that has been reported to Environmental Protection Administration to punish according to law.
There are currently 62 manufacturers participating in the independent management of road dust emission in the Industrial Park with about 6.29 km total length, and the operating method is mainly by manual cleaning. The total operation length is about 1,118.741 km in 2020, and the best vendors in the annual competition are Yuyang, Honglai, and Hongda. Patrol inspections were been implemented regularly for the dirty road in the Industrial Park, and the patrol inspection during the Program period resulted in the proportion of A-level roads was approximately 68.8%, and the proportion of B-level roads was approximately 31.2%. The Industrial Park road dirty hotspots include 3 factory entrances, 4 gravel plants. Besides that, Enrestec company has the lowest Class C status ratio, and the proportion of Class C status of SunnyWin, Fengsheng, and Tianren are on the high side. Although all Class C status has been requested to complete the improvement on the day of audit inspection, it continues to occur, and have been referred to the contractor for road dirty inspection. During the inspection, it was discovered that the entrance and exit of Yehui Company were dirty, and a fine was issued according to law.
The contacts between manufacturers in the Industrial Park and sensitive areas around the Industrial Park, Including the head of the township office, the village head, and teachers, a total of 70 groups joined the "Mobile Communication App Reporting Platform". After visiting 33 groups of representatives from the surrounding areas of the industrial zone during the Program period, about 18.2% of the respondents felt that the air quality in the neighboring Pingnan Industrial Park has been improved, which is higher than 6.1% of the respondents who felt that the air quality was worse. Most respondents (75.8%) expressed that the status of air quality wasn’t changed or wasn’t aware of. The proportion of respondents who feel that the air quality has improved is slightly lower than in 2019, but the percentage of respondents who felt that the status of air quality has deteriorated is significantly lower than that in 2019. Overall, the evaluation of respondents has improved compared with that in 2019.
By using air quilty microsensor to audit high concentration areas, As a result, a total of 11 cases in violation of Air Pollution Control were discovered, 8 cases of them have been reported, the total reported amount is currently NT$2.37 million.
