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-first Monthly EM&A report presenting the EM&A works carried out
during the period from 1 to 30 November 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:
Marine-based
Works
· Uninstallation
of marine piling platform
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 and
barriers installation; and

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 air quality monitoring
in the reporting month.
Breaches of Action
and Limit Levels for Water Quality
No exceedance
were recorded for water quality impact monitoring in the reporting month.
Impact
Dolphin Monitoring
One (1) Limit
Level exceedance was observed for the quarterly dolphin monitoring data between
September and November 2018, whilst 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 November 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.

Future Key
Issues
Potential
environmental impacts arising from the above upcoming construction activities
in the next reporting month of December 2018 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

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]).

survey effort was collected, with 83.8% 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 November 2018. Among
the two areas, 100.30 km and 167.69 km of survey effort were collected from NEL
and NWL survey areas, respectively. The total survey effort conducted on
primary and secondary lines were 192.71 km and 75.28 km, respectively.
The survey efforts are summarized in Appendix K.
Three (3) groups of five (5) Chinese White Dolphins was
sighted during the two sets of monitoring surveys in November 2018. The three dolphin sightings was made in NWL,
while none was sighted in NEL. During the surveys in November 2018, the three 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 November 2018 are shown in Tables 2.12 & 2.13.

One (1) Limit
Level exceedance was observed for the quarterly dolphin monitoring data between
September and November 2018, whilst 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 November 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, five (5)
site inspections were carried out on 2, 7, 14, 21 and 29 November 2018.
Key observations during the site inspections are
summarized in Table 2.14.
