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-second monthly EM&A Report for the Contract which summarizes
findings of the EM&A works during the reporting period from 1 to 31 May
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: 4, 10, 17, 24
and 31 May 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
was no Action Level and Limit Level exceedance of
Dissolved Oxygen (DO), Turbidity and Suspended Solids (SS) recorded by the
Environmental Team of Contract No. HY/2010/02 during the
reporting period.
Impact dolphin monitoring results at all transects are
reported in the EM&A Report prepared for Contract No. HY/2010/02.
Complaint Log
There
was no complaint received in relation to the environmental impact during the
reporting period.
Notifications of Summons and Successful
Prosecutions
There
was no notifications of summons or prosecutions
received during the reporting period.
Reporting Change
The
water quality monitoring stations at CS(Mf)3 (Coordinate: 809989E, 821117N),
IS10 (Coordinate: 812577E, 820670N) and SR5 (811489E, 820455N) have been occupied
by the marine work of a designated project - Expansion of Hong Kong
International Airport into a Three-Runway System (3RS Project). The alternative
water quality monitoring station at CS(Mf)3(N)
(Coordinate: 808814E, 822355N), IS10(N) (Coordinate: 812942E, 820881N) and
SR5(N) (812569E, 8201475N) 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.
The
change of transect lines 2, 3, 4, 5, 6 and 7 and new vessel-based transect line
24 for dolphin monitoring have been proposed due to the marine work of a
designated project - Expansion of Hong Kong International Airport into a
Three-Runway System (3RS Project). It was 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.

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, 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. |

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. |
