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.
Under
Contract No. HY/2012/07, Gammon Construction Limited (GCL) is commissioned by the
Highways Department (HyD) to undertake the design and
construction of the Southern Connection Viaduct Section of TM-CLKL (“the

The SS level at IS(Mf)16
during mid-ebb tide on 1 August 2015 was higher than the corresponding Action
Level but below 120% of the upstream control station at the same tide on the
same day. Thus the result was not
regarded as an exceedance.
No Action and Limit levels
exceedances was recorded at all monitoring stations for impact water quality
monitoring in the reporting month. No
action is thus required to be undertaken in accordance with the Event Action

The Action and Limit levels of
dolphin impact monitoring are shown in Appendix D. The Event and Action plan is presented in Appendix
L
.
A total of
297.72 km of survey effort was collected, with 99.6% 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 of
August 2015. Among the two areas, 113.58
km and 184.14 km of survey effort were collected from NEL and NWL survey areas
respectively. The total survey effort
conducted on primary and secondary lines were 215.91 km and 81.81 km
respectively. The survey efforts are
summarized in Appendix K.
Six (6)
groups of twenty-one (21) Chinese White Dolphins were sighted during the two
sets of monitoring surveys in August 2015.
During surveys of August 2015, all six (6) sightings were made in NWL,
while no dolphin was sighted in NEL.
During the surveys, all six (6) dolphin sightings were made on primary
lines during on-effort search, while none of the dolphin groups was associated
with operating fishing vessel. No
sighting was made 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
August 2015 are shown in Tables 2.12
& 2.13.

Note: Overall
dolphin encounter rates (sightings per 100 km of survey effort) from all four
surveys are conducted in August 2015 on primary lines only as well as both
primary lines and secondary lines in Northeast and Northwest Lantau
Whilst one (1) Limit Level exceedance
was observed for the quarterly dolphin monitoring data between June and August
2015. No unacceptable impact from the
construction activities of the TM-CLKL Southern Connection Viaduct Section on
Chinese White Dolphins was noticeable from general observations during the
dolphin monitoring in this reporting month.
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, 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 250 m marine mammal exclusion
zone monitoring was undertaken during the period of marine works activities
being undertaken. Passive Acoustic
Monitoring (PAM) was not implemented as the marine piling works were not
carried out outside the daylight hours in this reporting month. No sighting of Indo-Pacific humpback dolphin Sousa chinensis
(i.e. Chinese White Dolphin) were recorded in August 2015 during the exclusion
zone monitoring.
