This project has been started on 20 May 2014 at Yunlin. The project scope included operation, maintenance and calibration of equipment at Air Quality Monitoring Station and Meteorological Station, environmental noise monitoring, dioxin and heavy metal monitoring, dust monitoring at sensitive areas around Sixth Naphtha offshore industrial park, acid rain continuous monitoring station’s design and planning and maintenance of electronic board. The achievements of project were summarized as below:
1) 60 Air Quality Monitoring Station were performed scheduled monthly maintenance. All equipment was under normal operation and no overhaul was required during the project period.
2) Flow rate calibrations were completed on 17 June 2014 and 15 December 2014. The result regression coefficient R2 was 0.9999 which comply with the standard. (R2 shall be larger or equal to 0.995)
3) Multi-point calibrations were performed on 24 June 2014, 21 July 2014, 2 October 2014, 23 December 2014, 8 January 2015 and 1 April 2015. The results were fulfill with the standard requirements including flow accuracy shall be less than 5% difference and regression coefficient R2 shall be larger or equal to 0.995.
4) Every half of the month, one point calibrations were performed before and after sampling at each station. The flow accuracy shall be less than 7% difference.
5) The clock check was performed on 21 July 2014 and fulfilled the standard of less than 2 minutes difference.
6) For TSP monitoring, the highest (175 μg/m3) and lowest (14 μg/m3) concentration were found at chinhu elemetary school station. For dust monitoring, the highest concentration 34 kg/m2 per month was found at Beigang township office station, while the lowest 0.5 kg/m2 per month was recorded at Siluo township office station.
7) On 4 -5 March 2015, according to the sandstorm warning issued by EPA, temporary TSP monitoring was performed at Siluo township office station and recorded concentration of 76 μg/m3 which was far lower than limit (250 μg/m3). At the same period, the PM10 concentrations of other stations were relatively low except the 88μg/m3 at Mailiao station. Hence, it revealed that this area did not affected by sandstorm.
8) Ambient, highway and high speed rail noise monitoring have been performed 128 days and all results fulfilled the limit. According to historical monitoring data, in ambient noise monitoring, as Dounan station was sensitive to nearby residential activities, some intervals were found a high level of noise. In highway noise monitoring, each station were recorded a relatively steady noise level.
9) There were total 9 cases of noise complaints from residents. According to the land transportation noise limit, the monitoring results did not exceed the limit.
10) 12 times maintenances were completed at fixed noise monitoring station. The sources of noise were proposed. During weekdays, the noise would be come from high flow of vehicles at peak periods and operation of machine during gardening. During weekend, the sources would be park visitors and temporary exhibitions.
11) Checking of noise level from vehicles has been performed 35 times and checked 2,937 vehicles. 105 vehicles were requested to perform further noise assessment in which 77 vehicles passed, 28 vehicles unqualified and 7 vehicles unclassified. As selection by police before further assessment, the rate of unqualified was reach 27% and average exceed 4.5 dB of limit.
12) For general noise control area review and division of work, a conference was held on 8 December 2014. After one month public review, it has been put into practice on 9 April 2015 by Yulin government (ref.: 1043612088).
13) Ambient electromagnetic field (EMF) measurement was completed 20 pieces of extremely-low frequency and 21 pieces of high frequency. In which, 6 pieces of extremely-low frequency were performed at school area, 19 pieces of high frequency was performed at phone transmitting station. All the results were within the EPA limit.
14) At Lunbei junior high school station, 4 rounds of ambient dioxin sampling was completed on May, August, November 2014 and February 2015, while 2 rounds of heavy metal sampling was performed on May and August 2014. For ambient dioxin, sampling results were similar with the EPA historical Lunbei elemetary school station data. The results in winter and spring are more distinct than others. For heavy metal monitoring, iron, magnesium, aluminum and zinc were recorded relatively higher concentration. For mercury, comparing with 2013 Lunbei elemetary school station data, gaseous mercury was recorded a relatively higher concentration in this project, while concentration of solid mercury was relatively same. Also, the gaseous mercury had higher proportion to solid state. For chromium VI, sampling results were similar with historical data at all monitoring stations.
15) dust monitoring at sensitive areas around Sixth Naphtha offshore industrial park were completed 24 pieces of samples, ranging 42 -970 mg/m2 per day in concentration. Fengan elemetary school station was recorded relatively high concentration on October.
16) Operation and maintenance of meteorological station has been completed 60 months. Each station was operating normally with no damage. A abnormal signal transmission was recorded at Suntech elemetary school station on August 2014 and replacement of transmitter was performed on 7 August 2014.
17) For new acid rain continuous monitoring station’s design and planning, according to existing location of stations and analysis of relationship between sensitive area and Sixth Naphtha offshore industrial park, it proposed Goang-Shing elementary school as first priority while Sihhu township Neihu Elementary School as second.
18) 12 times of maintenance electronic board and 76 times of content update were recorded.
19) Sixth Naphtha offshore industrial park monitoring station audit were completed 7 times with satisfied result.
20) Hydrogen fluoride continuous monitoring has been perform at least one month at DouLiou MeiLin station(Located 590 meters Douliou fulltech fiber glass corporation South-East)and Yunlin Agriculture Expo parking lot (Located 2.17 km Huwei fulltech fiber glass corporation south-east). All monitoring result were satisfied with the air pollutant emission standard (60ppb).
