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 twenty-ninth monthly EM&A Report for the Contract which summarizes
findings of the EM&A works during the reporting period from 1 to 28 February
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-three 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: 1, 8, 15 and 22
February 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 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 three Action Level exceedances of suspended solids were recorded by the ET
of Contract No. HY/2010/02 during the reporting period. Action Level Exceedance
of SS at IS8 at Mid-Flood tide on 6 February 2017; Action Level Exceedance of
SS at SR6 at Mid-Ebb tide on 10 February 2017; and Action Level Exceedance of
SS at SR7 at Mid-Flood tide on 15 February 2017. After investigation, these
exceedances were considered not likely to be caused by this Contract’s
activities. 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.

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.

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. |
