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
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 Thirteenth Monthly EM&A report presenting the EM&A works carried
out during the period from 1 to 30 November 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 Works
¡P
Construction of Pile caps at Viaducts B and E;
¡P
Marine piling platform installation for Viaducts A, B,
C, D & E;
¡P
Marine Piling at Viaducts B, C, D & E; and
¡P
Additional marine ground investigation (GI) and
laboratory testing.
Land-based
Works
¡P
Construction of pile cap superstructure of Viaduct B;
¡P
Channel re-construction at Area 1;
¡P
Land Piling at Viaducts B, C & D;
¡P
Pre-drilling works at Viaduct A;
¡P
Construction of pile cap at Viaducts B & D;
¡P
Additional land GI, trial pits & lab testing;
¡P

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
Whilst
two (2) Action Level exceedances and no Limit Level exceedance were observed
for the quarterly dolphin monitoring data between September and November 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. 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 was carried out as there is 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 November 2014 during the exclusion zone monitoring.
Coral Monitoring
The First to Fourth Quarterly Post-Translocation
Coral Monitoring has been completed and the results were detailed in the First to Fourth Quarterly Post-Translocation Coral Monitoring Report.
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 December 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-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-354/2009A) was issued on 8 December 2010.

In accordance of the requirements stipulated in the Updated EM&A
Manual, High Volume Samplers (HVSs) were used for carrying out 1-hour and 24-hour
TSP monitoring on 5, 11, 17 and 20 November 2014 at ASR8 (Pak Mong Watch Tower) and on 5, 11, 17, 20 and 26 at ASR8A (Area
4). The TSP monitoring is detailed
in Figure 2.1 and Table
2.1. Wind anemometer was deployed
at the rooftop of Pak Mong Village Watch Tower for
logging wind speed and wind direction.
Copies of the calibration certificates for the
equipment are presented in Appendix
E. Details of the equipment deployed are
given in Table 2.2. Due to the rejection of access to Pak Mong Village, monitoring results of 1-hr TSP and 24-hr TSP
at ASR 8 and meteorological data was not recorded on 26 November 2014. The Proposal of Alternative Dust and Noise Monitoring Stations ([1])
was submitted to EPD on 2 December 2014, in which the HVS at ASR 8 was proposed to be relocated to
Entrance of MTR Depot and the wind anemometer to be relocated to ASR 8A in
accordance with the requirements of the Updated EM&A Manual.

All
1-hour and 24-hour TSP results were below the Action and Limit levels at all
monitoring locations in the reporting period. No action is thus required to be
undertaken in accordance with the Event Action Plan presented in Appendix L.
Noise
monitoring was performed on 5, 11, 17 and
20 November 2014 using
sound level meter at the designated monitoring station NSR 1 (Figure 2.2; Table 2.5) in accordance with the
requirements stipulated in the Updated EM&A Manual. Acoustic calibrator was deployed to
check the sound level meters at a known sound pressure level. Details of the deployed equipment are provided
in Table 2.6. Copies of the calibration certificates
for the equipment are presented in Appendix E. Due to the rejection of access to Pak Mong
Village, no noise monitoring results at NSR1 was recorded on 26 November
2014. The Proposal of Alternative Dust and Noise Monitoring
Stations ([2])
was submitted to EPD on 2 December 2014, in which the noise monitoring
station was proposed to be
relocated to the Pak Mong Village Pavilion in
accordance with the requirements of the Updated EM&A Manual.

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 six (6) groups of twenty-nine (29) Chinese
White Dolphins were sighted during the two sets of monitoring surveys in
November 2014. All sightings were
made in NWL during the two sets of surveys in November 2014, while no dolphin
was sighted at all in NEL in this month.
All except one (1) sighting 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. 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 November 2014 are shown in Tables 2.12 and 2.13.

Note: Overall
dolphin encounter rates (sightings per 100km of survey effort) from all four
surveys are conducted in November 2014 on primary lines only as well as both
primary lines and secondary lines in Northeast and Northwest Lantau
The average group size of
Chinese White Dolphins in November 2014 was 4.8 individuals per group, which
was higher than the ones in previous months of dolphin monitoring. Four (4) of the six (6) dolphin groups
were composed of one to four 1-4 animals, while only two (2) larger dolphin
groups with seven (7) and thirteen (13) animals were sighted during the
monitoring period. Detailed results
of dolphin monitoring in this reporting month are
presented in Appendix K.
Whilst
two Action Level exceedances (one Action Level exceedance for Northeast Lantau
social cluster; one Action Level exceedance for Northwest Lantau social
cluster) and no Limit Level exceedances were observed for the quarterly dolphin
monitoring data between September and November 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
during the dolphin monitoring in this reporting month.
Daily 250 m marine
mammal exclusion zone monitoring was undertaken during the period of marine
works activities being undertaken. No Passive Acoustic Monitoring
was carried out as there is 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 November 2014 during the exclusion zone monitoring.
The First to Fourth Quarterly Post-Translocation
Coral Monitoring have been completed and the results were detailed in the First to Fourth Quarterly Post-Translocation
Coral Monitoring Report. The
findings indicated that the Action or Limit Levels for coral monitoring were
not exceeded as increase in percentage of partial mortality was not detected
for both the tagged translocated and natural coral
colonies when comparing to the pre-translocation dataset.

Potential
environmental impacts arising from the above upcoming construction activities
in the next reporting month of December 2014 are mainly associated with dust, noise,
marine water quality, marine ecology and waste management issues.
This Thirteen Monthly
EM&A Report presents the findings of the EM&A activities undertaken
during the period from 1 to 30 November 2014, in accordance with the Updated
EM&A Manual and the requirements of EP-354/2009/B.
A total six
(6) groups of twenty-nine (29) Chinese White Dolphins were sighted during the
two sets of monitoring surveys in November 2014. All sightings were made in NWL during
the two sets of surveys in November 2014, while no dolphin was sighted at all
in NEL in this month. All except
one (1) sighting 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. Whilst two Action Level exceedances and no Limit Level
exceedances were observed for the quarterly dolphin monitoring data between
September and November 2014, no unacceptable impact from the construction activities
of the TM-CLKL Southern Connection Viaduct Section on Chinese White Dolphins
were 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.
