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 – 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-eighth Monthly EM&A report
presenting the EM&A works carried out during the period from 1 to 31
December 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
· Uninstallation
of marine piling platform;
· Pier
construction;
· Launching
gantry operation; and
· Installation
of deck segment and pier head segment.
Land-based Works
· Pier
construction;
· Re-alignment
of Cheung Tung Road;
· Road
works along North Lantau Highway;
· Installation
of pier head and deck segments; and
· Slope
work of Viaducts A, B & C.
A summary of monitoring and audit activities conducted
in the reporting period is listed below:
24-hour TSP Monitoring 6 sessions
1-hour TSP Monitoring 6 sessions
Noise Monitoring 6
sessions
Impact Water Quality Monitoring 14 sessions
Impact Dolphin Monitoring 2 sessions
Joint Environmental Site Inspection 4 sessions
Breaches of
Action and Limit Levels for Air Quality
No exceedance of Action and Limit Levels was recorded
for construction air quality monitoring in the reporting month.
Breaches of
Action and Limit Levels for Noise
No exceedance of Action and Limit Levels was recorded
for construction noise monitoring in the reporting month.
Breaches of
Action and Limit Levels for Water Quality
No exceedance of Action and Limit Levels was recorded
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 Indo-Pacific humpback dolphin Sousa chinensis
(i.e. Chinese White Dolphin) 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, in which 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 Chinese White Dolphin was
recorded in December 2016 during the exclusion zone monitoring.
Environmental
Complaints, Non-compliance & Summons
There was one (1) complaint received from EPD on 13
December 2016 regarding hammering noise nuisance generated during midnights 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 January 2017 include the following:
Marine Works
· Uninstallation
of marine piling platform;
· Pier
construction;
· Launching
gantry operation; and

Future Key
Issues
Potential environmental impacts arising from the above
upcoming construction activities in the next reporting month of January 2017
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 – Zhuhai – Macao Bridge (HZMB). In order to cope with the anticipated traffic
demand, two new road sections between NWNT and North Lantau – Tuen Mun – 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 295.50 km of survey effort was collected,
with 96.3% 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 December 2016. Among the two
areas, 116.10km and 179.40 km of survey effort were collected from NEL and NWL
survey areas, respectively. The total
survey effort conducted on primary and secondary lines were 212.93 km and 82.57
km, respectively. The survey efforts are
summarized in Appendix K.
Six (6) groups of 24 Chinese White Dolphins were sighted during the two sets of monitoring surveys in
December 2016. All six (6) dolphin sightings were made in
NWL, while none was sighted in NEL.
During the surveys in December 2016, five of the six sightings were made
on primary lines during on-effort search.
None of the dolphin groups was associated with operating fishing vessel
and none of the dolphin groups were 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 December 2016 are shown in Tables 2.12 & 2.13.

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, in which 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 Chinese White Dolphin was
recorded in December 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, four
(4) site inspections were carried out on 7, 14, 22 and 29 December 2016.
Key
observations during the site inspections are summarized in Table 2.14.
