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 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, EP-354/2009/C and EP-354/2009/D, were granted on 28 January 2014, 10 December 2014
and 13 March 2015, 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 Eighteenth Monthly EM&A report presenting the EM&A works carried
out during the period from 1 to 30 April 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 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. Passive Acoustic Monitoring (PAM) was
implemented when the marine piling works were 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 April 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.

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

Although
depth-averaged
SS on 2 and 7 April during ebb-tide and flood-tide, and 28 April during
ebb-tide were observed higher than the Action Level[JY2] [JY3] ,
the results were lower than 120% of the upstream control at the same tide of
the same day. As such, the above
depth-averaged SS results were considered as sporadic events of natural
variation in water quality. No
Action and Limit levels exceedances was thus recorded at all monitoring
stations for impact water quality monitoring in the reporting month. No action was required to be undertaken
in accordance with the Event Action Plan presented in Appendix L.

The average group size of Chinese White Dolphins in
April 2015 was 4.33 individuals per group, which was slightly higher than the
ones in previous months of dolphin monitoring. Two (2) of the three (3) dolphin groups
were composed of two to three (2-3) dolphins, while another larger group of
eight (8) dolphins were also sighted during the monitoring period.
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.[JY4]
Daily 250 m marine
mammal exclusion zone monitoring was undertaken during the period of marine works
activities being undertaken.
Passive Acoustic Monitoring (PAM) was implemented when the marine piling
works were 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 April 2015 during the exclusion
zone monitoring.

Potential
environmental impacts arising from the above upcoming construction activities
in the next reporting month of May 2015 are mainly associated with dust, noise,
marine water quality, marine ecology and waste management issues.
This
Eighteenth Monthly EM&A Report presents the findings of the EM&A
activities undertaken during the period from 1 to 30 April 2015, in accordance
with the Updated EM&A Manual and the requirements of the Environmental Permit (EP-354/2009/D).
Three (3)
groups of thirteen (13) Chinese White Dolphins were sighted during the two sets
of monitoring surveys in April 2015.
All sightings were made in NWL, with no dolphin being sighted at all in
NEL. During surveys in April 2015,
only one (1) of the three (3) sightings was 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.
