Section of the Tuen Mun ¡V Chek Lap Kok Link Project (TM-CLK
Link Project) while AECOM Asia Company Limited was appointed by HyD as the Supervising Officer. For implementation of the environmental
monitoring and audit (EM&A) programme under the
Contract, ERM-Hong Kong, Limited (ERM) has been appointed as the Environmental
Team (ET). ENVIRON Hong Kong Ltd.
was employed by the HyD as the Independent

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 June 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 July 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 ¡V Zhuhai ¡V Macao Bridge (HZMB). In order to cope with the anticipated
traffic demand, two new road sections between NWNT and North Lantau ¡V Tuen Mun ¡V 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 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 301.30 km of
survey effort was collected, with 91.6% 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 June 2015. Among the two areas, 115.90 km and
185.40 km of survey effort were collected from NEL and NWL survey areas
respectively. The total survey
effort conducted on primary and secondary lines were 220.07 km and 81.23 km
respectively. The survey efforts
are summarized in Appendix K.
Three (3) groups of fifteen
(15) Chinese White Dolphins were sighted during the two sets of monitoring
surveys in June 2015. Two (2)
sightings were made in NWL, while one (1) sighting of a lone dolphin was made
in NEL. During surveys of June 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 June 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
June 2015 during the exclusion zone monitoring.

Potential
environmental impacts arising from the above upcoming construction activities
in the next reporting month of July 2015 are mainly associated with dust,
noise, marine water quality, marine ecology and waste management issues.
This
Twentieth Monthly EM&A Report presents the findings of the EM&A
activities undertaken during the period from 1 to 30 June 2015, in accordance
with the Updated EM&A Manual and the requirements of the Environmental Permit (EP-354/2009/D).
Three
(3) groups of fifteen (15) Chinese White Dolphins were sighted during the two
sets of monitoring surveys in June 2015.
Two (2) sightings were made in NWL, while one (1) sighting of a lone
dolphin was made in NEL. During
surveys of June 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.
The
ET will keep track on the construction works to confirm compliance of
environmental requirements and the proper implementation of all necessary
mitigation measures.
