monitoring in the reporting period.
Impact Dolphin Monitoring
During this month of
dolphin monitoring, no unacceptable impact from the construction activities of
the TM-CLKL Southern Connection Viaduct Section on Chinese White Dolphins 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, 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 monitoring was undertaken during the period of
marine works under this Contract. No
Passive Acoustic Monitoring (PAM) was implemented as the marine works were not
carried out outside the daylight hours in this reporting month. No sighting of the Indo-Pacific humpback
dolphin Sousa chinensis
(i.e. Chinese White Dolphin) was recorded in July 2015 during the exclusion
zone monitoring.

Future Key Issues
Potential
environmental impacts arising from the above upcoming construction activities
in the next reporting month of August 2015 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 2010.

The SS level at IS8 during mid-ebb tide on 25 July
2015 was higher than the corresponding Action Level but not higher than 120% of
the upstream control station at the same tide on 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 Plan presented in Appendix L.

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 301.62 km of survey effort was collected,
with 87.2% 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 July 2015. Among the two
areas, 116.10 km and 185.52 km of survey effort were collected from NEL and NWL
survey areas respectively. The total
survey effort conducted on primary and secondary lines were 219.76 km and 81.86
km respectively. The survey efforts are
summarized in Appendix K.
Three (3) groups of six (6) Chinese White Dolphins
were sighted during the two sets of monitoring surveys in July 2015. All three (3) sightings were made in NWL, while no dolphin was sighted in NEL. During surveys
of July 2015, all three (3) dolphin sightings were made on primary lines during
on-effort search, and 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 July 2015 are shown in Tables 2.12 & 2.13.

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
July 2015 during the exclusion zone monitoring.

Potential
environmental impacts arising from the above upcoming construction activities
in the next reporting month of August 2015 are mainly associated with dust, noise,
marine water quality, marine ecology and waste management issues.
This
Twenty-first Monthly EM&A Report presents the findings of the EM&A
activities undertaken during the period from 1 to 31 July 2015, in accordance
with the Updated EM&A Manual and the requirements of the Environmental Permit (EP-354/2009/D).
Three
(3) groups of six (6) Chinese White Dolphins were sighted during the two sets of
monitoring surveys in July 2015. All
three (3) sightings were made in NWL, while no dolphin was
sighted in NEL. During surveys of July 2015, all three (3) dolphin
sightings were made on primary lines during on-effort search, and none of the
dolphin groups was associated with operating fishing vessel. No sighting was made in the proximity of the
Project’s alignment. During this month of dolphin monitoring, no
unacceptable impact from the construction activities of the TM-CLKL Southern
Connection Viaduct Section on Chinese White Dolphins was noticeable from
general observations.
There
was no environmental complaint, notification of summons or successful
prosecution recorded in the reporting period.
The
ET will keep track on the construction works to confirm compliance of
environmental requirements and the proper implementation of all necessary
mitigation measures.
