This project has been started on August 20, 2015. The project scope included operation, maintenance and calibration of equipment at manual Air Quality Monitoring Station and Meteorological Station, environmental noise monitoring, dust monitoring at sensitive areas around Sixth Naphtha offshore industrial park, check of equipment at Air Quality Monitoring Station belonging to the Sixth Naphtha offshore industrial park check and maintenance of electronic board. The achievements of project were summarized as below:
1)65 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 11 September 2015 and 7 March 2016. 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 22 September 2015, 7 October 2015, 5 January 2016, 28 March 2016, 6 April 2016 and 5 July 2016. 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 1 September 2015 and fulfilled the standard of less than 2 minutes difference.
6)For TSP monitoring, the highest (61 μg/m3) and lowest (53 μg/m3) average concentration were found at Huwei station and Siluo station. For dust monitoring, the highest concentration 34.6 kg/m2 per month was found at Siluo station in October 2015, while the lowest 0.2 kg/m2 per month was recorded at Huwei station in August 2015.
7)Ambient, highway and high speed rail noise monitoring have been performed 148 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.
8)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.
9)Checking of noise level from vehicles has been performed 35 times and checked 2,198 vehicles. 66 vehicles were requested to perform further noise assessment in which 40 vehicles passed, 15 vehicles unqualified and 15 vehicles unclassified. As selection by police before further assessment, the rate of unqualified was reach 27 % and average exceed 5.6 dB of limit.
10)Ambient electromagnetic field (EMF) measurement was completed 20 pieces of extremely-low frequency and 21 pieces of high frequency. In which, 10 pieces of extremely-low frequency were performed at school area, 10 pieces of extremely-low frequency were performed at Floor type transformers, 21 pieces of high frequency was performed at phone transmitting station. All the results were within the EPA limit.
11)The noise poster design was completed and 500 posters had been printed.
12)24-day monitoring of the mobile air quality monitoring vehicle had been completed. All the results were within the EPA air quality standard.
13)dust monitoring at sensitive areas around Sixth Naphtha offshore industrial park were completed 24 pieces of samples, ranging 23.2 -339 mg/m2 per day in concentration. From November 2016 onwards, the reason for the high value of the measurement has the northeast monsoon caused by the external transmission and bare ground. In addition to the monitoring results of the project, the EPA PM10 measurements also had the same trend.
14)Sixth Naphtha offshore industrial park monitoring station audit were completed 10 times with satisfied result.
15)Operation and maintenance of meteorological station had been completed 60 months. Each station was operating normally with no damage. The equipment boxs were broken by the erosion of sea breeze at Suntech elemetary school station and North gate hostel station on October 2015 and replacement of the equipment box was performed on 1 October 2015.
16)12 times of maintenance electronic board and 169 times of content update were recorded.
