Executive SUMMARY

 

This Monthly Environmental Monitoring and Audit (EM&A) Report is prepared for Contract HY/2013/02 ¡§Hong Kong¡VZhuhai-Macao Bridge Hong Kong Boundary Crossing Facilities (HKBCF) ¡V 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¡VZhuhai¡VMacao 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-eighth 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 November to 30 November 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/2011/03 ¡§Hong Kong-Zhuhai-Macao Bridge Hong Kong Link Road ¡V Section between Scenic Hill and HKBCF¡¨ and Contract No. HY/2013/04 HZMB HKBCF ¡V Infrastructure Works Stage II (Southern Portion). 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 NMS3C, 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/2011/03 and HY/2013/04. However, this is subject to ENPO¡¦s final decision on which ET should carry out the monitoring works at these stations.

 

Due to the commence operation of HKBCF on 24 October 2018, environmental site inspection would only be conducted if there are any ad-hoc construction works within the construction site of Contract No. HY/2013/02. In November 2018, there were no ad-hoc construction works raised by the Contractor and thus no environmental site inspection had been conducted during the reporting month.

 

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/2013/04 during the reporting period.

 

There was no Action and Limit Level exceedance for noise recorded at station NMS2 and station NMS3C by the Environmental Team of Contract No. HY/2013/04 during the reporting period.

 

During November 2018, there were 5 action level exceedance of suspended solids. The following table summarized the number of exceedance on each sampling data.

The dolphin monitoring works for the Contract are covered by Contract No. HY/2013/04 HZMB HKBCF ¡V Infrastructure Works Stage II (Southern Portion). The ET of the Contract or another ET of the HZMB project is required to conduct dolphin monitoring at 24 transects as part of EM&A programme if these transects are no longer covered under Contract No. HY/2013/04. The dolphin monitoring should adopt line-transect vessel survey method. The survey follows pre-set and fixed transect lines in the two areas defined by AFCD as: Northeast Lantau survey area; and Northwest Lantau survey area. Figure 3 shows the co-ordinates for the transect lines and layout map.

 

5.2.         Monitoring Requirements

The monitoring requirements, monitoring equipment, monitoring parameters, frequency and duration, monitoring methodology, monitoring schedule, meteorological information are detailed in the monthly EM&A Reports prepared for Contract No. HY/2013/04.

 

5.2.1.     The event and action plan is provided in Appendix D.

 

5.2.2.     The Action and Limit Levels for Chinese White Dolphin Monitoring are provided in Table 5.1a & Table 5.1b

5.2.3.     If exceedance(s) at these transects is/are recorded by the ET of the Contract or referred by the other ET under the HZMB project to the Contract, the ET of the Contract will carry out an investigation and findings will be reported in the monthly EM&A Report.


 

 

5.3          Monitoring Result

The dolphin survey results for all transects are reported in the monthly EM&A Reports prepared for Contract No. HY/2013/04.

 

6.            ENVIRONMENTAL SITE INSPECTION AND AUDIT

 

6.1.         Site Inspection

 

6.1.1.     Site Inspections were carried out on a weekly basis to monitor the implementation of proper environmental pollution control mitigation measures for the project. Due to the commence operation of HKBCF on 24 October 2018, environmental site inspection would only be conducted if there are any ad-hoc construction works within the construction site of Contract No. HY/2013/02. In November 2018, there were no ad-hoc construction works raised by the Contractor and thus no environmental site inspection had been conducted during the reporting month.

 

6.2.         Advice on the Solid and Liquid Waste Management Status

 

6.2.1.     The Contractor registered as a chemical waste producer for the Contract. Sufficient numbers of receptacles were available for general refuse collection and sorting. The quantities of waste for disposal in this reporting period are summarized in Table 6.1 and Table 6.2 and monthly summary waste flow table is shown in Appendix E.
