(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 third monthly EM&A report presenting the EM&A works carried out
during the period from 1 to 31 January 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 Survey tower erection;
¡P Marine piling platform installation;
¡P Construction of rockfill platform at Viaduct D
landing; and
¡P Additional marine ground investigation (GI) and laboratory testing.
Land-based
Works
¡P SOR¡¦s site offices erection at Area 5;
¡P Satellite container offices erection along seawall (i.e. CEDD Access
Road);
¡P Fence relocation for Viaducts A, C & D;
¡P Piling platform installation for Viaduct B;

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. Sighting of the Indo-Pacific humpback
dolphin Sousa chinensis
was recorded on 23 January 2014 during the exclusion zone monitoring.
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.
Upcoming Works for the Next Reporting Period
Works to be
undertaken in the next monitoring period of February 2014 include the
following:
Marine
Works
¡P Marine
piling platform installation;
¡P Survey
tower erection;
¡P Construction
of rockfill platform at Viaduct D landing;
¡P Additional
marine ground investigation (GI) and laboratory testing;
¡P Marine
Bored Piling.
Land-based

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

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 19 groups
of 78 Chinese White Dolphin sightings were recorded
during the two sets
of surveys in January 2014. All
except one sighting were made in NWL during the two sets of surveys in January,
with another group of nine animals being sighted in NEL. All except four sightings were made on
primary lines during on-effort search, and none of the dolphin groups was
associated with an operating fishing vessel.
The
majority of these dolphin sightings in January 2014 were made around Lung Kwu Chau and near Black Point, while a lone sighting was
made in the Northeast Lantau near Siu Ho Wan along
the north shoreline of Lantau. It is noted that this lone sighting near
Siu Ho Wan was located at less than 2 km from TM-CLKL Southern Connection Viaduct Section,
which coincides with the dolphin sighting reported by the Marine Mammal
Exclusion Zone Monitoring (see Section
2.4.8). 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 with good visibility) in January 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 February 2014 are mainly associated with dust, noise,
marine water quality, marine ecology and waste management issues.
This third Monthly
EM&A Report presents the findings of the EM&A activities undertaken
during the period from 1 to 31 January 2014, in accordance with the Updated
EM&A Manual and the requirements of EP-354/2009/A.
A total of nineteen (19) groups
of seventy-eight
(78) dolphin sightings were recorded during the two sets of
surveys. All except one sighting were made in
NWL during the two sets of surveys in January, with another group of nine
animals being sighted in NEL. A lone
sighting of dolphin was recorded near Siu Ho Wan which is located at less than
2 km from TM-CLKL
Southern Connection Viaduct Section. During this reporting period 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.
Air
Quality Impact
¡P All
working plants and vessels on site should be regularly inspected and properly
maintained by the Contractor to avoid dark smoke emission.
¡P Open
stockpiles should be properly covered by the Contractor.
¡P The
Contractor should provide water spraying to suppress fugitive dust for any
dusty construction activity.
Construction
Noise Impact
¡P Vessels
and equipment operating should be checked regularly and properly maintained by
the Contractor.
Water Quality
Impact
¡P The
Contractor should regularly review and maintain drainage systems to make sure
they are functioning effectively.
¡P Proper
drainage channels, bunds and set-up should be provided by the Contractor at the
site to collect/ intercept the surface run-off or waste water generated from
works area to ensure no direct discharge from site to surrounding water bodies.
Chemical and
Waste Management
¡P All
types of wastes should be collected and sorted accordingly and removed timely
by the Contractor. They should be
properly stored in designated areas within the works areas temporarily.
¡P All
plants and vehicles on site should be properly maintained by the Contractor and
drip trays should be provided where appropriate to prevent oil leakage.
¡P All
drain holes of the drip trays within the works areas should be properly plugged
by the Contractor to avoid any oil and chemical waste leakage.
¡P Oil
stains on soil surface should be cleared and disposed of as chemical waste by
the Contractor.
¡P Floating
debris and trash observed within the silt curtain and around the working barge
should be collected as far as possible to maintain the cleanliness of the
surrounding sea.
