Gammon Construction Limited (GCL) is commissioned by the Highways Department (HyD) to undertake the design and construction of the Southern
Connection Viaduct 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 Environmental Checker (IEC) and Environmental Project Office (ENPO)
in accordance with Environmental Permit
No. EP-354/2009/A.
Further applications
for variation of environmental permit (VEP), EP-354/2009/B and EP-354/2009/C,
were granted on 28 January 2014 and 10 December 2014, respectively.
The
construction phase of the Contract commenced on 31 October 2013 and will
tentatively be completed by 2018.
The impact monitoring of the EM&A programme, including air quality,
noise, water quality and marine ecological monitoring as well as environmental
site inspections, commenced on 31 October 2013.
This
is the Fifteenth Monthly EM&A report presenting the EM&A works carried
out during the period from 1 to 31 January 2015 for the Southern
Connection Viaduct Section in accordance with the Updated EM&A Manual of the
TM-CLK Link Project. As informed by the Contractor, major

Breaches of Action and Limit Levels for Air Quality
No exceedance
of Action and Limit Levels was recorded for construction air monitoring in the
reporting month.
Breaches of Action and Limit Levels for Noise
No exceedance
of Action and Limit Levels was recorded for construction noise monitoring in
the reporting month.
Breaches of Action and Limit Levels for Water Quality
No exceedance
of Action and Limit Levels was recorded for impact water quality monitoring in
the reporting month.
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
carried out as there was no marine works 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 January 2015 during the exclusion
zone monitoring.
Environmental Complaints, Non-compliance & Summons
No environmental
complaint, notification of summons and successful prosecution was received in
the reporting month.
Reporting Change
There was no
reporting change required in the reporting period.

Future Key Issues
Potential
environmental impacts arising from the above upcoming construction activities
in the next reporting month of February 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 eleven (11) groups of forty-six (46) Chinese White Dolphins were
sighted during the two sets of monitoring surveys in January 2015. All sightings were made in NWL during
the two sets of surveys in January 2015, while no dolphin was sighted at all in
NEL in this month. Eight (8) of the
eleven (11) 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 sightings 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 January 2015 are shown in Tables 2.12 and 2.13.

The average group size of
Chinese White Dolphins in January 2015 was 4.18 individuals per group, which
was slightly higher than the ones in previous months of dolphin monitoring. Five (5) of the eleven (11) dolphin
groups were composed of five to eight (5-8) dolphins during the monitoring
period. Detailed results of dolphin monitoring in this reporting month are presented in Appendix K.
Daily 250 m marine
mammal exclusion zone monitoring was undertaken during the period of marine
works activities being undertaken. No Passive Acoustic Monitoring (PAM) was
carried out as there was no marine works 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 January 2015 during the exclusion zone monitoring.

Potential
environmental impacts arising from the above upcoming construction activities
in the next reporting month of February 2015 are mainly associated with dust, noise,
marine water quality, marine ecology and waste management issues.
This Fifteenth
Monthly EM&A Report presents the findings of the EM&A activities
undertaken during the period from 1 to 31 January 2015, in accordance with the
Updated EM&A Manual and the requirements of the Environmental Permit (EP-354/2009/C).
A total of
eleven (11) groups of forty-six (46) Chinese White Dolphins were sighted during
the two sets of monitoring surveys in January 2015. All sightings were made in NWL during
the two sets of surveys in January 2015, while no dolphin was sighted at all in
NEL in this month. Eight (8) of the
eleven (11) 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.
