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 Fifty-fifth Monthly EM&A report
presenting the EM&A works carried out during the period from 1 to 31 May
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
· Pier
construction;
· Re-alignment
of Cheung Tung Road;
· Road
works along North Lantau Highway;
· Installation
of pier head and deck segments;
· Asphalt

Introduction
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.

Monitoring Parameter, Frequencies and Duration
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.

Action
& Limit
Levels
The Action and Limit levels of dolphin impact
monitoring are shown in Appendix D. The Event and Action plan is presented in Appendix L.
2.4.6
Monitoring Schedule for the
Reporting Month
Dolphin monitoring was carried out on 7, 10, 16 and 30
May 2018 (Appendix F).
2.4.7
Results and Observations
A total of 261.40 km of survey effort was collected,
with 83.9% 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 May 2018. Among the two
areas, 95.70 km and 165.70 km of survey effort were collected from NEL and NWL
survey areas, respectively. The total
survey effort conducted on primary and secondary lines were 189.44 km and 71.96
km, respectively. The survey efforts are
summarized in Appendix K.
No Chinese White Dolphins were sighted during the two sets of monitoring surveys in
May 2018.
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 May 2018 are
shown in Tables 2.12 & 2.13.

One (1) Limit Level exceedance was
observed for the quarterly dolphin monitoring data between March and May 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.
2.4.8
Marine Mammal Exclusion Zone Monitoring
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 May 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.
2.5
EM&A
Site Inspection
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,
9, 16, 23 and 31 May 2018.
Key
observations during the site inspections are summarized in Table 2.14.
