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 (VEP)
(EP-354/2009/A) was issued on 8 December 2010.
Subsequent applications for variation of environmental permits (VEPs), 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.

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 2.3. The co-ordinates of all transect lines are
shown in Table 2.8 below.

No dolphin sighting was made in the
proximity of the TM-CLKL alignment. The
distribution of dolphin sightings during the reporting month is shown in Figure 2.4.
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 2017 with the results present in Tables 2.9 and 2.10.

Note: Overall dolphin encounter
rates (sightings per 100 km of survey effort) from all four surveys are
conducted in December
2017 on primary lines only as well as both primary
lines and secondary lines in Northeast and Northwest Lantau.
Due to monthly variation in dolphin
occurrence within the survey area, it would be more appropriate to draw
conclusion on whether any unacceptable impacts on dolphins have been detected
in relation to the construction activities of this Project 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 was in effect during the period of dredging,
reclamation or marine sheet piling works in open waters under this
Contract. No sighting of the
Indo-Pacific humpback dolphin Sousa chinensis (i.e.
Chinese White Dolphin) was recorded in December 2017 during the exclusion zone
monitoring.
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, 13, 20 and 27 December 2017.
