l Storm, sewer drainage and water main construction;
l Cable trench and ducting;
l Landscaping work
Environmental Monitoring and Audit Progress
The monthly 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/2013/01 “Hong Kong-Zhuhai-Macao Bridge HKBCF – Passenger Clearance Building” 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 show in Figure 2 and dolphin monitoring show in Figure 3 as part of EM&A programme if these monitoring stations are no longer covered under Contract No. HY/2013/01 and HY/2011/03. However, this is subject to ENPO’s final decision on which ET should carry out the monitoring works at these stations. The dates of site inspection during the reporting period are listed below:
Environmental Site Inspection: 07, 14, 21 & 28 December 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 shall be referred to 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/2013/01 during the reporting period.
There was an Action Level exceedance of 24-hr TSP level recorded at station AMS3B by the Environmental Team of Contract No. HY/2013/01 during the reporting period.

Since the removal of temporary loading and unloading point by Contract No. HY/2013/02, which involved marine work, was completed on 10 September 2017 and the area was handed back to Reclamation Contractor with Contract No. HY/2010/02 on 11 September 2017 for subsequent seawall construction as confirmed by RSS, there was no marine works or barge of this Contract worked at HKBCF reclamation site near the sea area or area near the monitoring station under Contract No. HY/2013/02 during December 2017. Hence, no investigation report was provided for all exceedances recorded under Contract No. HY/2013/02 in December 2017. There was no Action and Limit Level exceedance recorded on other monitoring date at the monitoring stations showed at Table 4.1 by the Environmental Team of Contract No. HY/2013/01 during the reporting period.
Complaint Log
During December 2017, there was a complaint received by Highway Department on 29 December 2017 and referred to the ENPO on 08 January 2018. Then the ENPO forwarded the complaint by email to the R.E. (AECOM), the Contractor (China Harbour) and the ET (ETS-Testconsult Ltd.) of Contract No. HY/2013/02 at 12:20 on 08 January 2018. The complaint detail was "投訴人投訴於大嶼山東岸路，因港珠澳大橋工程的沙塵問題，部門安排了有關洗街車及吸塵車處理有關沙塵問題，但有關車輛就上述問題的處理成效未如理想。投訴人表示洗街車在清洗有關路面時，只是向路面灑水，令原本的沙塵變成泥漿，但卻沒有清理有關泥漿，道路問題根本沒有根治。另外，有關吸塵車的隔濾亦未如理想，吸塵車吸了地上的沙塵後所噴出來的氣體佈滿沙塵，以致有關沙塵除了未被吸走外，更導致道路沙塵滾滾。要求部門監察有關承辦商，煩請部門跟進及回覆。" The complaint is under investigation and to be reported in the next reporting month.
Notifications of Summons and Successful Prosecutions
There were no notifications of summons or prosecutions received during the reporting period.
Reporting Change
Due to topographical conditions of SR3, SR10A and SR10B(N), the water quality monitoring (WQM) stations was proposed to be monitored at alternative WQM stations.
As such, proposal for alternation of water quality monitoring stations for HZMB HKBCF was justified by the ET Leader for Contract No. HY/2013/01 on 08 November 2017; verified by the IEC on 13 November 2017; and submitted to EPD on 29 November 2017, and it was approved by EPD on 22 December 2017.
Future Key Issues
The future key issues to be undertaken in the upcoming month are as follows:
l Road and Bituminous works;
l Branch, collector drain, gully & u-channel;
l Cable trench and ducting;
l Landscaping work
