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) –
Passenger Clearance Building (hereafter referred to as “the Contract”) for the
Highways Department of Hong Kong Special Administrative Region (HKSAR). The
Contract was awarded to Leighton – Chun Wo Joint Venture (hereafter referred to
as “the Contractor”) and Atkins China 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 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 thirty-fifth monthly EM&A Report for the Contract which summarizes
findings of the EM&A works during the reporting period from 1 to 31 August
2017.
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 – 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 twenty-one stations (nine Impact Stations, seven Sensitive Receiver Stations
and five Control/Far Field Stations) and dolphin monitoring works at twenty-four
transects as part of EM&A programme if these monitoring stations/transects 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/transects.
The dates of site inspection during the reporting
period are
listed below:
Environmental
Site Inspection: 2,
9, 16, 25 and 30 August 2017

Remark:
(1)
The ET of
this Contract should conduct impact air quality monitoring at the AMS listed in
the table as part of EM&A programme according to the latest notification from ENPO when the monitoring
station(s) is/are no longer covered by another ET of the HZMB project.
(2)
The original
monitoring location was at Hong Kong SkyCity Marriott Hotel (AMS7). As the permission to carry out air
quality monitoring at Hong Kong SkyCity Marriott Hotel was not granted after 31
January 2015, the monitoring location was relocated to Chu Kong Air-Sea Union
Transportation Co. Ltd. (AMS7A) from 5 February 2015 to 30 December 2015. The alternative monitoring location at Chu
Kong Air-Sea Union Transportation Co. Ltd. was approved by EPD on 5 February
2015. However, AMS7A was
relocated back to its original location (AMS7-Hong Kong SkyCity Marriott Hotel)
on 30 December 2015. The relocation
of air quality monitoring location, AMS7A, back to AMS7 was approved by EPD on
21 December 2015.

Remarks: (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, 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. (c)
The change
of transect lines 2, 3, 4, 5, 6 and 7 and new transect line 24 were justified
and verified by the ET Leader for Contract No. HY/2010/02 and the IEC
respectively on 24 March 2017 and it was approved by EPD on 12 May 2017. |
