There are 90 factories installed at present, of which 47 are under control for fixed pollution sources, 33 are not under control, 5 are temporarily suspended and 5 are in installation with a total employment of approximately 3,666.
There were total of 710 patrol inspections in the Industrial Park factories between Januray and November 2019 with 27 abnormal or deficient conditions were found during the inspection, including 4 abnormal odors, 4 abnormal emissions, 13 abnormal equipment, and 6 dust powder emissions (2 cases are the same with the abnormal equipment), 3 polluted roads (1 case is the same with the abnormal equipment), accounted for about 3.8% of the total number of inspections, about 2.1% lower than the same period in 2018. Most of which were confirmed with completion of improvement by re-examination, however, Xingwei, Fuguangxin and Jian Shin Factory 1 had repeated occurrences and the quality of improvement was not good. Among them, the abnormal or deficient conditions of Xingwei Company has been significantly improved after the replacement of new crucible boiler, and the control of Fuguangxin and Jian Shin Factory 1 still needs to be strengthened.
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, Yuh Kang Elementary School PM10 in the first and fourth quarters and Donghai Primary School SO2 in the second quarter second were significantly higher for a short period of time. With reference to the PM2.5 monitoring results of the neighboring air quality sensors, it is determined that it is caused by surrounding pollution sources or human activities and not sourced from the Pingnan Industrial Park. Furthermore, the Donghai Primary Shool NMHC was significantly higher for a short period of time in the second quarter. With reference to the VOCs monitoring results of the neighboring air quality sensors, it is determined that the source should be from the Mandarin Decor Co., Ltd. in the Industrial Park.
In the sampling analysis of Dioxin in the perimeter air and sediment this year, the average value of Dioxin in the perimeter air was 0.013 (standard deviation 0.006, excluding PCBs) pg I-TEQ/m3, the average concentration of total toxicity equivalent is about 0.013 pg WHO2005-TEQ/m3 (including PCBs) after converted with WHO2005-TEF and included in the PCBs, which is far lower than the annual average of Japan's environmental quality air standard of 0.6 pg WHO2005-TEQ/m3. PCBs account for about 6.1 to 16.7% of the total toxicity equivalent, and compared with the proporation of PCBs (0~50%) in the monitoring results of Air Quality Monitoring Stations summarized by the Environmental Protection Administration 2018 "Environmental Toxic Air Pollutant Discharge Investigation, Monitoring and Control Strategy Development Program," the effect of PCBs in the air on the total toxic equivalents of Dioxin in the air this year the total toxicity of PCBs in the air to Dioxin in the air this year is not significant; the range of concentration in the fourth quarter of this year is closer to the 2018 Program and the 2000 Kanding Incinerator Plant perimeter. The concentration of sediment samples this year was 1.810~2.294 ng I-TEQ/kg, which was in line with the lower limit value of the "Regulaions for Classification Management of Sediment Quality Indicator and Restrictions for Use" by the Environmental Protection Administration, Executive Yuan. The concentration range is relatively close to that of Baoshan Reservoir, Dajia River and Houlong River without abnormal situation.
3 PSN inspections, 3 Dioxin inspections, 1 verification of VOCs reduction rate, 1 inspection of PM2.5 and TSP, and 1 inspection of 24 heavy metals have been implemented in the gas duct inspection. The inspection results are in compliance with the regulatory standards. However, the exhaust volume of Yu Lai Co., Ltd. exceeded the permitted range during during the inspection of Dioxin and has been reported with ticket issued for alleged violation according to law.
The odor organic function measurement has been implemented 9 times, including 3 times on the perimeter and 6 times gas duct, of which, 3 measurements of gas duct odor were used to support the audit inspection of the non-Pingnan Industrial Park of the Environmental Protection Administration. For the audit inspection part of Pingnan Industrial Park, the inspection results of Mandarin Decor Co., Ltd. with gas duct odor, Lianyou Metals with gas duct odor and Huihua Company perimeter order exceeded the control standard, and the Environmental Protection Administration has report to punish the alleged violation according to law.
There are currently 62 manufacturers who participated in the independent management of road dust emission in the Industrial Park with about 6.33 km total length of sponsorship. The sponsorship operating method is mainly by manual cleaning with about 1,162.903 km total length of sponsorship operation from January to November of 2019, and Hsin Hwa Chemical, AROCHEM and GS-Granite are the best in current stage annual evaluation results. Patrol inspections were implemented regularly for the dirty road in the Industrial Park, and the patrol inspection during the Program period resulted in the proportion of Class A roads was approximately 67.8%, and the proportion of Class B roads was approximately 32.2%. Affected by the road construction in the Industrual Park, stricter dirty judgment standards and part of the factories pollution in 2019, the proportion of Class A roads is relatively lower; with the Industrial Park road dirty hotspots include 1 bare ground, 4 factory entrances and exits, and 2 sand and gravel plants, with higher propertion of Class C for SunnyWin, Fengsheng, Kuncheng, and Tianren, and all Class C conditions have been requested to complete the improvement on the day of audit inspection; in addition, the improvement for four other road dirty reports from the Environmental Protection Administration have been completed, and the dirty locations have been included in the Industrial Park Road Dirty Hotspot to strengthen the control.
The contacts between manufacturers in the Industrial Park and sensitive areas around the Industrial Park, including representatives of township offices, village chiefs and school staff member representatives, a total of 64 have joined the "Mobile Communication app Reporting Platform." A total of 36 visits were made during the Program period, and about 22.2% of the respondents felt that the air condition in the neighboring Pingnan Industrial Park has been improved, which is higher than 19.4% of the respondents who felt that the air condition was worse. Most respondents (58.3%) expressed that the status of air quality was not changed or was not aware of, and the proportion of respondents who felt improved air quality condition was slightly lower than that of in 2016 and 2018, and higher proportion of respondents who felt the air quality condition was worse. After comparing the 2019 complaint cases and public reported information, the main complaint sources have been targeted to strengthen patrol inspections or conducted counselling for improvement.
Through this Program to strengthen control, strengthen audit inspection, use micro-sensor to audit and invite experts and scholars to strengthen inspection and counseling of the improvement measures, the Pingnan Industrial Park has been repeatedly complained by the factories (Jian Shin Factory 1, Jian Shin Factory 2, Eternal Materials, Mandarin Decor and Shin Foong) in 2018, compared the cases of complaints in January ~ November, 2019 over the same period in 2018, the number of repeated complaint cases of the aforementioned five factories has been reduced by 50, and the total number of cases of existing pollution sources in the Industrial Park was reduced by 68 cases (about 67% reduction) from 102 cases to 34 cases compared with the same period of 2018.
