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. Another application
for variation of environmental permit (VEP) (EP-354/2009/B) was granted on 28 January 2014.
The
construction phase of the Contract commenced on 31 October 2013 and will be
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
seventh monthly EM&A report presenting the EM&A works carried out
during the period from 1 to 31 May 2014 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
activities in the reporting period included:
Marine-based
Works
¡P Marine
piling platform installation;
¡P Marine
piling at Viaducts B & E;
¡P Construction
of rockfill platform at Viaduct D landing; and
¡P Additional
marine ground investigation (GI) and laboratory testing.
Land-based
Works
¡P Satellite
container offices erection along seawall (i.e. CEDD Access Road);
¡P Fence
installation and relocation of Area 2, Viaducts A, B, C & D;
¡P Land

Breaches of Action and Limit Levels for Air Quality
No exceedance
of Action and Limit Levels was recorded for construction noise 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
Whilst two
Action Level exceedances and no Limit Level
exceedance were observed for the quarterly dolphin monitoring data between
March and May 2014, no unacceptable impact from the construction activities of
the TM-CLKL Southern Connection Viaduct Section on Chinese White Dolphins was
noticeable from general observations in May. 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. No sighting of the Indo-Pacific humpback
dolphin Sousa chinensis
(i.e. Chinese White Dolphin) was recorded in May 2014 during the exclusion zone
monitoring.
Coral Monitoring
No
Post-Translocation Coral Monitoring Exercise was conducted in the reporting
month in May 2014.
Environmental
Complaints, Non-compliance & Summons
No 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 June 2014 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-145/2009), 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-354/2009A) 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 Contract¡¨) while AECOM

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 9 groups
of 30 Chinese White Dolphin sightings were recorded
during the two sets
of surveys in May 2014. All
sightings were made in NWL during the two sets of surveys in April,
with no dolphin being sighted at all in NEL. All except one sighting 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
TM-CLKL Southern Connection Viaduct Section. 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 May 2014 with the results presented in Tables 2.12 and 2.13.

Potential
environmental impacts arising from the above upcoming construction activities
in the next reporting month of June 2014 are mainly associated with dust,
noise, marine water quality, marine ecology and waste management issues.
This Seventh
Monthly EM&A Report presents the findings of the EM&A activities
undertaken during the period from 1 to 31 May 2014, in accordance with the
Updated EM&A Manual and the requirements of EP-354/2009/B.
A total of nine (9) groups of thirty (30) dolphin
sightings were recorded during the two sets of surveys in May 2014. All
sightings were made in NWL during the two sets of surveys in May 2014, with no
dolphin being sighted at all in NEL.
During this reporting period of dolphin monitoring,
whilst two Action Level exceedances and no Limit
Level exceedances were recorded for the quarterly
dolphin monitoring data between March and May 2014, 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.
