Executive Summary

This monthly Environmental Monitoring and Audit (EM&A) Report is prepared for Contract HY/2013/01 Hong Kong-Zhuhai-Macao Bridge Hong Kong Boundary Crossing Facilities (HKBCF) ˇV Passenger Clearance Building (hereafter referred to as ˇ§the Contractˇ¨) for the Highways Department of Hong Kong Special Administrative Region (HKSAR). The Contract was awarded to Leighton ˇV Chun Wo Joint Venture (hereafter referred to as ˇ§the Contractorˇ¨) and Atkins China Limited was appointed as the Environmental Team (ET) by the Contractor.

The Contract is part of Hong Kong ˇV Zhuhai ˇV Macao Bridge HKBCF which is a ˇ§Designated Projectˇ¨, 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 started on 26 September 2014 and the construction works of the Contract commenced on 6 October 2014.

Atkins China 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 will be providing environmental team services to the Contract.

This is the twenty-sixth monthly EM&A Report for the Contract which summarizes findings of the EM&A works during the reporting period from 1 to 30 November 2016.

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, noise, water quality and dolphin monitoring works for the Contract are covered by Contract No. HY/2010/02 Hong Kong-Zhuhai-Macao Bridge HKBCF ˇV Reclamation Works and Contract No. HY/2011/03 Hong Kong-Zhuhai-Macao Bridge Hong Kong Link Road ˇV 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 and noise monitoring at NMS2 and NMS3B 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 ENPOˇ¦s final decision on which ET should carry out the monitoring work at these stations. 

The dates of site inspection during the reporting period are listed below:

Environmental Site Inspection:          2, 9, 15, 23 and 30 November 2016

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 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 NMS2 and NMS3B by the Environmental Team of Contract No. HY/2010/02 during the reporting period.

There were eleven Action Level exceedances and one Limit Level exceedance of suspended solids were recorded by the ET of Contract No. HY/2010/02 during the reporting period. Action Level Exceedances of SS at IS8 and SR4(N) at Mid-Flood tide on 14 November 2016; Action Level Exceedance of SS at IS10 and SR5 & Limit Level Exceedance of SS at SR6 at Mid-Flood tide on 16 November 2016; Action Level Exceedance of SS at IS(Mf)11, IS10, SR5, SR6, SR7 at Mid-Flood tide on 18 November 2016. Action Level Exceedance of SS at SR10A and SR10B(N) at Mid-Flood tide on 30 November 2016. Based on the information from the Contractor of this Contact, no marine works or marine transportation were undertaken on the relevant dates. Therefore, these exceedances were considered not likely to be caused by this Contractˇ¦s activities after investigation. No follow up action is required.

Impact dolphin monitoring results at all transects are reported in the EM&A Report prepared for Contract No. HY/2010/02.

5        Dolphins Monitoring

5.1          Monitoring Location[TI1] 

5.1.1       The dolphin monitoring works for the Contract are covered by Contract No. HY/2010/02 Hong Kong-Zhuhai-Macao Bridge HKBCF ˇV Reclamation Works. The ET of the Contract or another ET of the HZMB project is required to conduct dolphin monitoring at the twenty-three transects as part of EM&A programme if these transects are no longer covered under Contract No. HY/2010/02. 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 5.1 shows the co-ordinates for the transect lines and layout map.

5.1.2       The co-ordinates for the transect lines and a layout map showing the transect lines have been provided by AFCD and are shown in Table 5.1.

Remark:

(a)    *Due to the presence of deployed silt curtain systems at the site boundaries of the Contract, some of the transect lines shown in Figure 5.1 could not be fully surveyed during the regular survey. Transect 10 is reduced from 6.4km to approximately 3.6km in length due to the HKBCF construction site. Therefore the total transect length for both NEL and NWL combined is reduced to approximately 108km

(b)    Coordinates for transect lines 1, 2, 7, 8, 9 and 11 have been updated in respect to the Proposal for Alteration of Transect Line for Dolphin Monitoring approved by EPD on 19 August 2015.
