This Monthly Environmental Monitoring and Audit (EM&A) Report is prepared for Contract HY/2013/02 “Hong Kong–Zhuhai-Macao Bridge Hong Kong Boundary Crossing Facilities (HKBCF) – Infrastructure Works Stage I (Western Portion)” (hereafter referred to as “the Contract”) for the Highways Department of Hong Kong Special Administrative Region (HKSAR). The Contract was awarded to China Harbour Engineering Co., Ltd. (hereafter referred to as “the Contractor”) and ETS-Testconsult Limited was appointed as the Environmental Team (ET) by the Contractor.
The Contract is part of Hong Kong–Zhuhai–Macao Bridge HKBCF which is a “Designated Project”, under Schedule 2 of the Environmental Impact Assessment Ordinance (EIAO) (Cap 499) and Environmental Impact Assessment (EIA) Report (Register No. AEIAR-145/2009) was prepared for the Project. The current Environmental Permit (EP) No. EP-353/2009/K for HKBCF was issued on 11 April 2016. These documents are available through the EIA Ordinance Register. Site preparation works of the Contract was started on 25 July 2014 and the construction works of the Contract commenced on 24 November 2014.
ETS-Testconsult Limited has been appointed by the Contractor to implement the Environmental Monitoring & Audit (EM&A) programme for the Contract in accordance with the Updated EM&A Manual for HKBCF (Version 1.0) and provide environmental team services to the Contract.
This is the forty-fourth Monthly Environmental Monitoring and Audit (EM&A) Report for the Contract which summaries findings of the EM&A works conducted during the reporting period from 01 July to 31 July 2018.
Site Activities
As confirmed by RSS, the capital works were substantially completed on 28 March 2018. Site activities were carried out in this reporting month as informed by the Contractor:
l Establishment work for Landscape
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 AMS7B, 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: 05, 12, 19 & 26 July 2018
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 AMS7B by the Environmental Team of Contract No. HY/2013/01 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/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 July 2018. Hence, specific investigation shall be referred to other ET’s report(s) under the HZMB Projects in which the respective contract(s) with remaining marine works on-going for the exceedances recorded in water quality monitoring during this reporting month. 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
Follow-up action to the complaint received by Highways Department on 13 June 2018 and referred to the ENPO on 22 June 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 10:42 on 25 June 2018. After received the details of the complaint from the ENPO on 25 June 2018, a related follow-up inspection was conducted by ET and the Contractor of Contract No. HY/2013/02 to investigate this event. The inspection was concentrated to check if there is any improper discharged by Contract No. HY/2013/02. After checked with the Contractor of Contract No. HY/2013/02, only Box Culvert A is within our site boundary. There was no any muddy water discharge observed during inspection on 25 June 2018. Besides, during weekly environmental site inspection on 27 June 2018, Box Culvert A was checked and inspected. No muddy water discharge was observed. Besides, the capital works were substantially completed on 28 March 2018 and no construction activities that would generate wastewater with high concentrations of suspended solid were conducted on 13 June 2018. Moreover, as discussed with the contractor, all the washing/de-silting/removal of grit works inside manholes has been completed before 30 April 2018 and no exposed earth ground was observed during the inspection. Hence, the complaint received on 13 June 2018 was found non-related to Contract No. HY/2013/02. The complaint investigation report (Log No. 019) was provided in Appendix J.
