Under Contract No. HY/2012/07,
Gammon Construction Limited (GCL) is commissioned by the Highways Department (HyD) to undertake the design and construction of the
Southern Connection Viaduct Section of the Tuen Mun ¡V Chek Lap Kok Link Project (TM-CLK Link Project) while AECOM
Asia Company Limited was appointed by HyD as the
Supervising Officer. For
implementation of the environmental monitoring and audit (EM&A) programme under the Contract, ERM-Hong Kong, Limited (ERM)
has been appointed as the Environmental Team (ET). Ramboll
Environ Hong Kong Ltd. was employed by the HyD as the
Independent Environmental Checker (IEC) and Environmental Project Office (ENPO)
in accordance with Environmental Permit
No. EP-354/2009/A.
Further applications for variation of
environmental permit (VEP), EP-354/2009/B, EP-354/2009/C and EP-354/2009/D, were granted on 28 January 2014, 10 December 2014
and 13 March 2015, respectively.
The southern landfall of TM-CLK Link lies alongside the Hong Kong -
Zhuhai - Macao Bridge Hong Kong Boundary Crossing Facilities (HKBCF) where a
reclamation area is constructed by Contract
No. HY/2010/02 under Environmental
Permit No. EP-353/2009/K and
EP-354/2009/D. Upon the
agreement and confirmation between the Supervising Officer Representatives and
Contractors of HY/2010/02 and HY/2012/07 in September 2015, part of
the reclamation area for southern landfall under EP-353/2009/K and
EP-354/2009/D was handed-over to Contract
No. HY/2012/07. Another part of the southern landfall
area under EP-354/2009/D was
handed-over to Contract No. HY/2012/07
after completion of reclamation works by Contract
No. HY/2010/02 in June 2016.
The construction phase of the Contract commenced on 31
October 2013 and will be tentatively completed by 2018. The impact monitoring of the EM&A programme, including air quality, noise, water quality and
marine ecological monitoring as well as environmental site inspections,
commenced on 31 October 2013.
This is the Thirty-fifth Monthly EM&A report
presenting the EM&A works carried out during the period from 1 to 30
September 2016 for the Southern Connection Viaduct
Section in accordance with the Updated EM&A Manual of the
TM-CLK Link Project. As informed by the Contractor, major
activities in the reporting period included:
Marine Works
¡P Uninstallation
of marine piling platform;
¡P Pier
construction;
¡P Launching
gantry operation; and
¡P Installation
of deck segment and pier head segment.

for water quality impact monitoring in the reporting period.
Impact Dolphin
Monitoring
During this month of dolphin monitoring, no
unacceptable impact from the construction activities of the TM-CLKL Southern
Connection Viaduct Section on Chinese White Dolphins was noticeable from
general observations. Due to
monthly variation in dolphin occurrence within the study area, it would be more
appropriate to draw conclusion on whether any impacts on dolphins have been
detected related to the construction activities of the TM-CLKL Southern
Connection Viaduct Section in the quarterly EM&A reports, where comparison
on distribution, group size and encounter rates of dolphins between the
quarterly impact monitoring period and baseline monitoring period will be made.
Daily marine mammal exclusion zone monitoring was
undertaken during the period of marine works under this Contract. No sighting of the Indo-Pacific humpback
dolphin Sousa chinensis
(i.e. Chinese White Dolphin) was recorded in September 2016 during the
exclusion zone monitoring.
Environmental
Complaints, Non-compliance & Summons
There was one (1) complaint received from EPD on 22
September 2016 regarding effluent discharge from flat top barge in the
reporting period. Upon
investigation, the complaint is considered not related to this Project.
There was no notification of summons or successful
prosecution recorded in the reporting period.
Reporting
Change
There was no reporting change in the reporting period.
Upcoming Works for the Next Reporting Period
Works to be undertaken in the next monitoring period
of October 2016 include the following:

Future Key
Issues
Potential environmental impacts arising from the above
upcoming construction activities in the next reporting month of October 2016
are mainly associated with dust, noise, marine water quality, marine ecology
and waste management issues.
According to the findings of the Northwest New
Territories (NWNT) Traffic and Infrastructure Review conducted by the Transport
Department, Tuen Mun Road,
Ting Kau Bridge, Lantau Link and North Lantau Highway
would be operating beyond capacity after 2016. This forecast has been based on the
estimated increase in cross boundary traffic, developments in the Northwest New
Territories (NWNT), and possible developments in North Lantau, including the
Airport developments, the Lantau Logistics Park (LLP) and the Hong Kong ¡V
Zhuhai ¡V Macao Bridge (HZMB). In
order to cope with the anticipated traffic demand, two new road sections
between NWNT and North Lantau ¡V Tuen Mun ¡V Chek Lap Kok Link (TM-CLKL) and Tuen Mun Western Bypass (TMWB) are proposed.
An Environmental Impact Assessment (EIA) of TM-CLKL
(the Project) was prepared in accordance with the EIA Study Brief (No. ESB-175/2007) and the Technical
Memorandum of the Environmental Impact Assessment Process (EIAO-TM). The EIA Report was submitted under the
Environmental Impact Assessment Ordinance (EIAO) in August 2009. Subsequent to the approval of the EIA
Report (EIAO Register Number AEIAR-146/2009), an Environmental Permit (EP-354/2009) for TM-CLKL was granted by
the Director of Environmental Protection (DEP) on 4 November 2009, and EP
variation (EP-354/2009/A) was issued
on 8 December 2010.

The Action and Limit levels of dolphin impact
monitoring are shown in Appendix D. The Event and Action plan is presented
in Appendix L.
A total of 297.13 km of survey effort was collected,
with 92.7% of the total survey effort being conducted under favourable weather
conditions (i.e. Beaufort Sea State 3 or below with good visibility) during the
surveys in September 2016. Among
the two areas, 113.60 km and 183.53 km of survey effort were collected from NEL
and NWL survey areas respectively.
The total survey effort conducted on primary and secondary lines were
212.25 km and 84.88 km respectively.
The survey efforts are summarized in Appendix K.
Four (4) groups of 21 Chinese White Dolphins were sighted during the two sets of monitoring surveys in
September 2016. All four (4) dolphin sightings were made
in NWL, while none was sighted in NEL.
During the surveys in September 2016, all sightings were made on primary
lines during on-effort search. None
of the dolphin groups was associated with operating fishing vessel or sighted
in the proximity of the Project¡¦s alignment. The distribution of dolphin sighting
during the reporting month is shown in Figure 2.5.
Encounter
rates of Chinese White Dolphins are deduced from the survey effort and
on-effort sighting data made under favourable
conditions (Beaufort 3 or below) in September 2016 are shown in Tables 2.12 & 2.13.

During
this month of dolphin monitoring, no adverse impact from the construction
activities of the TM-CLKL Southern Connection Viaduct Section on Chinese White
Dolphins was noticeable from general observations.
Due
to monthly variation in dolphin occurrence within the study area, it would be
more appropriate to draw conclusion on whether any impacts on dolphins have
been detected related to the construction activities of the TM-CLKL Southern
Connection Viaduct Section in the quarterly EM&A reports, where comparison
on distribution, group size and encounter rates of dolphins between the
quarterly impact monitoring period and baseline monitoring period will be made.
Daily 250 m marine mammal exclusion zone
monitoring was undertaken during the period of daytime marine works
activities. No sighting of
Indo-Pacific humpback dolphin Sousa chinensis (i.e. Chinese White Dolphin) were recorded in
September 2016 during the exclusion zone monitoring.
Passive Acoustic Monitoring (PAM) had
been decommissioned as no marine piling works was carried out outside the
daylight hours since September 2015.
Site
inspections were carried out on a weekly basis to monitor the implementation of
proper environmental pollution control and mitigation measures under the
Contract. In the reporting month,
five (5) site inspections were carried out on 2, 7, 14, 21 and 29 September
2016.
Key
observations during the site inspections are summarized in Table 2.14.
