Executive Summary
This Quarterly
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)
¡V 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 ¡V 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 ¡V Zhuhai ¡V 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 (Version1.0) and will be providing
environmental team services to the Contract.
This is the twelfth Quarterly EM&A Report for the Contract which summaries findings of
the EM&A works during the reporting period from 1 July to 31 August 2017 in
order to tally with the project dolphin monitoring quarterly review cut-off as
per ENPO¡¦s advice in consultation with EPD and AFCD.
Environmental
Monitoring and Audit Progress
The 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 ¡V Reclamation Works and Contract No. HY/2011/03
Hong Kong-Zhuhai-Macao Bridge Hong Kong Link Road ¡V 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, 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.
A
summary of the monitoring activities during the reporting period are listed
below:

Breaches of
Action and Limit Levels
Summary of Action
and Limit Level exceedance of 1-hr TSP level and 24-hr TSP level at station
AMS6 shall be referred to the monthly EM&A Reports (for July and August
2017) 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 two
Action Level exceedance of Suspended Solids (SS) recorded by the ET of Contract
No. HY/2010/02 during the reporting period (for July and August 2017). Based on
the information from the Contractor of this Contract, no marine transportation and
marine works were being done during the relevant water quality monitoring period.
Therefore, 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.
Implementation of Environmental
Measures
Site inspections were
carried out on a weekly basis to monitor the implementation of proper
environmental pollution control and mitigation measures for the Project.
Potential environmental impacts due to the construction activities were monitored
and reviewed.
Complaint Log
There
was no complaint received in relation to the environmental impact during the
reporting period.
There were two complaints
received in relation to the environmental impact during the previous reporting
period.
A
summary of environmental complaints for the previous reporting period is as
follows:

area at the Northern side of the Island. As confirmed by the Contractor, works
area at the Northern side of the Island is not
under this contract.
For the dust complaint received by EPD and sent to the
ET on 6 June 2017, a weekly site inspection was conducted by the ET and Contractor on 7 June 2017 for the
construction site area under Contract No. HY/2013/01.
During the site inspection, the access road was observed wet and no adverse
dust impact was observed.
Notifications
of Summons and Successful Prosecutions
There was no notification
of summon or prosecution received during this reporting period.
Reporting
Change
The reporting period of
this Quarterly EM&A Report from 1 July to 31 August 2017 in order to tally with

Remarks:
(1)
The ET of
this Contract should conduct impact air quality monitoring at the Air
Monitoring Station 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.
(3)
The ET of
this Contract should conduct impact noise monitoring at the NMS 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.
(4)
The Action
and Limit Levels for schools will be applied for this alternative monitoring
location.

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. |
