This is the 7th Quarterly EM&A Report for the Contract which summaries findings of the EM&A works during the reporting period from 01 March 2017 to 31 May 2017 (includes the findings of the EM&A programme of Contract No. HY/2013/06 within Contract No. HY/2013/03 works area during the reporting period from 01 March 2017 to 31 May 2017) (the “reporting period”).
Environmental Monitoring and Audit Progress
The EM&A programme was undertaken in accordance with the Updated EM&A Manual for HKBCF (Version 1.0). It should be noted that the air quality and noise monitoring works for the Contract are covered by Contract No. HY/2010/02 “Hong Kong-Zhuhai-Macao Bridge HKBCF – Reclamation Works” and Contract No. HY/2011/03 “Hong Kong-Zhuhai-Macao Bridge Hong Kong Link Road – Section between Scenic Hill and HKBCF”. The ET of the Contract or another ET of the HZMB project is required to conduct impact air quality monitoring at AMS6 and AMS7, noise monitoring at NMS2 and NMS3B, water quality monitoring at the locations shown in Figure 3 and ecological monitoring as shown in Figure 4 and Figure 5 as part of EM&A programme if these monitoring stations are no longer covered under Contract Nos. HY/2010/02 and HY/2011/03. However, this is subject to ENPO’s final decision on which ET should carry out the monitoring work at these stations.
The dates of site inspection for Contract No. HY/2013/03 (includes Contract No. HY/2013/06 within Contract No. HY/2013/03 works area) during the reporting period are listed below:
Environmental Site Inspection:
· 02, 09, 16, 24 and 30 March 2017
· 05, 12, 20 and 28 April 2017
· 05, 11, 18 and 26 May 2017
Breaches of Action and Limit Levels
Summary of Action and Limit Level exceedance of 1-hr TSP level and 24-hr TSP level at AMS6 is reported in the monthly EM&A report prepared by Contract No. HY/2011/03.
There was no Action and Limit Level exceedance of 1-hr TSP level and 24-hr TSP level recorded at station AMS7 by the Environmental Team of Contract No. HY/2010/02 during the reporting period.
There was no Action and Limit Level exceedance for noise recorded at station NMS2 and station NMS3B by the Environmental Team of Contract No. HY/2010/02 during the reporting period.
As silt curtain was installed on 11 May 2017 and therefore, water monitoring result is reported from May. There was no Action and Limit Level exceedance for water quality recorded at the monitoring stations shown at Table 2.2 by the Environmental Team of Contract No. HY/2010/02 during May.
Ecological monitoring results at all transects are reported in the EM&A report prepared by Contract No. HY/2010/02.
