Future
Key Issue
Potential
environmental impacts arising from the above upcoming construction activities
in the next reporting month of May 2019 are mainly associated with dust, 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 (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

Note: Overall dolphin encounter
rates (sightings per 100 km of survey effort) from all four surveys are
conducted in April 2019
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 Contract 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 silt curtain installation in open waters under this
Contract. No sighting of the Indo-Pacific
humpback dolphin Sousa chinensis (i.e. Chinese White Dolphin) was recorded in
April 2019 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 3, 10, 17 and 24 April 2019.
Key
observations and recommendations during the site inspections in this reporting
period are summarized in Table 2.11.
