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 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 2019. 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 sixty-second Monthly EM&A report
presenting the EM&A works carried out during the period from 1 to 31
December 2018 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:
Land-based Works
· Reinstatement
works along Cheung Tung Road;
· Abutment
construction;
· Road
works along North Lantau Highway;
· Asphalt
paving;
· Construction
of sign gantries, light poles and street furniture;
· Parapets

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 2018 during the exclusion zone monitoring.
Environmental
Complaints, Non-compliance & Summons
No complaints, 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 2019 include the following:
Marine-based Works
· Uninstallation
of marine piling platform
Land-based Works
· Reinstatement

Future Key
Issues
Potential environmental impacts arising from the above
upcoming construction activities in the next reporting month of January 2019
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.

recorded for water quality impact monitoring in the reporting month. No action is required to be undertaken in
accordance with the Event Action Plan as presented in Appendix
L.
Impact dolphin monitoring is required to be conducted
by a qualified dolphin specialist team to evaluate whether there have been any
effects on the Indo-Pacific humpback dolphin Sousa chinensis (i.e. Chinese White Dolphin) from the
Contract. In order to fulfil the
EM&A requirements and make good use of available resources, the on-going
impact line transect dolphin monitoring data collected by HyD’s Contract No. HY/2011/03 Hong
Kong-Zhuhai-Macao Bridge. Hong Kong Link Road - Section between Scenic Hill and
Hong Kong Boundary Crossing Facilities on the monthly basis is adopted to
avoid duplicates of survey effort.

Dolphin
monitoring should cover all transect lines in Northeast Lantau
(NEL) and the Northwest Lantau (NWL) survey areas twice per month throughout the entire
construction period. The monitoring data
should be compatible with, and should be made available for, long-term studies
of small cetacean ecology in Hong Kong.
In order to provide a suitable long-term dataset for comparison,
identical methodology and line transects employed in baseline dolphin
monitoring was followed in the impact dolphin monitoring.
The
impact dolphin monitoring was carried out in the NEL and NWL along the line
transect as depicted in Figure 2.4. The co-ordinates of all transect lines are
shown in Table 2.11
below ([1]).

areas, 97.00 km and 164.96 km of survey effort were collected from NEL and NWL
survey areas, respectively. The total
survey effort conducted on primary and secondary lines were 193.46 km and 68.50
km, respectively. The survey efforts are
summarized in Appendix K.
Two (2) groups of six (6) Chinese White Dolphins
was sighted during the two sets of monitoring surveys in
December 2018. Both dolphin
sightings was made in NWL, while none was sighted in NEL. During the surveys in December
2018, the two sightings was
made during on-effort search, while all of them was sighted on primary
line. None of the dolphin groups was
associated with operating fishing vessel and was not 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 2018 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 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 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 2018 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 6, 11, 18 and 27 December 2018.
Key
observations during the site inspections are summarized in Table 2.14.
