Introduction
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 – Zhuhai – Macao Bridge (HZMB).
In order to cope with the anticipated traffic demand, two new road
sections between NWNT and North Lantau – Tuen Mun – 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. Another application for variation of
environmental permit (VEP) (EP-354/2009/B)
was granted on 28 January 2014.
Under

EM&A
RESULTS
The EM&A
programme required environmental monitoring for air quality, noise, water
quality and marine ecology as well as environmental site inspections for air
quality, noise, water quality, waste management, marine ecology and landscape
and visual impacts. The EM&A
requirements and related findings for each component are summarized in the
following sections.
The baseline
air quality monitoring undertaken by the Hong Kong – Zhuhai –Macao Bridge Hong
Kong Projects (HKZMB) during October 2011 has included the two monitoring
stations ASR9A and ASR9C for this project.
Thus, the baseline monitoring results and Action/ Limit Level presented
in HKZMB Baseline Monitoring Report () are
adopted for this Project.
2.1.1
Monitoring Requirements and Equipment
In accordance with the Updated EM&A Manual, impact 1-hour TSP monitoring was conducted three (3)
times every six (6) days while the highest dust impact was expected. Impact 24-hour TSP monitoring was carried
out once every six (6) days. The
Action and Limit Level of the air quality monitoring is provided in Appendix D.
Air quality
monitoring stations ASR9A and ASR9C in Siu Ho Wan MTRC Depot were the proposed
locations in accordance with the Updated EM&A Manual. However, authorization of getting access
into Siu Ho Wan MTRC Depot is still being sought for the impact monitoring of
the EM&A programme for the captioned Contract. Air quality monitoring stations in Siu Ho Wan MTRC
Depot (ASR9A and ASR9C) were relocated to Area 4 (ASR8A) and rooftop of Pak Mong Village (ASR8) respectively since November 2013. A proposal for setting up
alternative air quality monitoring stations at ASR8A (Area 4) and ASR8 (Rooftop
of Pak Mong Village Watch Tower) was submitted on 13
November 2013 which was subsequently approved. Same baseline and Action Level for air quality, as
derived from the baseline monitoring data recorded at Siu Ho Wan MTRC Depot,
were adopted for these temporary air quality locations (Figure
2.1; Table
2.1).
High Volume
Samplers (HVSs) were used for carrying out 1-hour and 24-hr TSP monitoring during
the reporting period from March to May 2014. The HVS meets all requirements of the Updated
EM&A Manual. Brand and model of
the equipment is given in Table 2.2.
Wind
data monitoring equipment has been installed at the rooftop of Pak Mong Village Watch Tower during the reporting period for
logging wind speed and wind direction.
The wind sensor was setup such as it was clear of obstructions or
turbulence caused by building. The
wind data monitoring equipment is recalibrated at least once every six months.

A total of sixteen monitoring events were
undertaken in the reporting period with no Action Level and Limit Level
exceedance recorded at all monitoring stations in the reporting period. No action is thus required to be
undertaken in accordance with the Event Action Plan presented in Appendix
J.
Major noise sources during the noise
monitoring included construction activities, nearby traffic noise and aircraft
noise.
The baseline
water quality monitoring undertaken by the Hong Kong – Zhuhai – Macao Bridge
Hong Kong Projects (HKZMB) between 6 and 31 October 2011 has included all
monitoring stations except SR4a for the Project. Thus, the baseline monitoring results
except for station SR4a and Action/Limit Level presented in HKZMB Baseline
Monitoring Report () are
adopted for this Project. Baseline
water quality monitoring was conducted at station SR4a from 29 August to 24
September 2013.
2.3.1
Monitoring Requirements and Equipment
Impact water quality monitoring was carried out to
ensure that any deterioration of water quality was detected, and that timely
action was taken to rectify the situation.
Impact water quality monitoring was undertaken three days per week
during the construction period at seven (7) water quality monitoring stations
in accordance with the Updated EM&A Manual (Figure 2.3; Table 2.8).

Action or Limit Level exceedance were recorded during the reporting quarter.
2.4.1
Monitoring Requirements
Impact dolphin
monitoring is required to be conducted by a qualified dolphin specialist team
to evaluate whether there have been any effects on the dolphins. In order to fulfil the EM&A
requirements and make good use of available resources, the on-going impact line
transect dolphin monitoring data collected by HyD’s Contract No. HY/2011/03 Hong Kong-Zhuhai-Macao Bridge. Hong
Kong Link Road - Section between Scenic Hill and Hong Kong Boundary Crossing
Facilities on the monthly basis is adopted to avoid duplicates of survey
effort.

Monitoring Parameter, Frequencies & Duration
Dolphin
monitoring should cover all transect lines in Northeast Lantau (NEL) and the
Northwest Lantau (NWL) survey areas twice per month throughout the entire construction
period. The monitoring data should
be compatible with, and should be made available for, long-term studies of
small cetacean ecology in Hong Kong. In order to provide a suitable long-term
dataset for comparison, identical methodology and line transects employed in
baseline dolphin monitoring was followed in the impact dolphin monitoring.
2.4.4
Monitoring Location
The impact
dolphin monitoring was carried out in the NEL and NWL along the line transect
as depicted in Figure 2.4. The

2.4.7
Results & Observations
A total of 891.87
km of survey effort was collected, with 87.4% of the total survey effort being
conducted under favourable weather conditions (i.e. Beaufort Sea State 3 or
below with good visibility). Among
the two areas, 350.40 km and 541.47 km of survey effort were collected from NEL
and NWL survey areas respectively. The
total survey effort conducted on primary lines was 642.67 km, while the effort
on secondary lines was 249.20 km. Both
survey effort conducted on primary and secondary lines
were considered as on-effort survey data. The survey efforts are summarized in Appendix I.
A total of 31 groups
of 103 Chinese White Dolphin sightings were recorded during the six sets of surveys
from March to May 2014.
All except one
sighting were made during on-effort search. Twenty-five on-effort sightings
were made on primary lines, while another five on-effort sightings were made on
secondary lines. In this quarterly
period, all dolphin groups were sighted in NWL, while none was sighted in NEL.
Encounter
rates of Chinese White Dolphins deduced from the survey effort and on-effort

During this quarter of dolphin
monitoring, no unacceptable impact from the activities of this Contract was
recorded from the general observations. Although the dolphins infrequently
occurred along the alignment of TMCLKL southern connection viaduct in the past
and during the baseline monitoring period, it is apparent that dolphin usage
has been significantly reduced in NEL, and many individuals have shifted away
from the important habitat around the Brothers Islands.
It is critical to monitor the dolphin
usage in North Lantau region in the upcoming quarters, to determine whether the
dolphins are continuously affected by the various construction activities in
relation to the HZMB-related works, and whether suitable mitigation measure can
be applied to revert the situation.
2.4.8
Marine Mammal Exclusion Zone Monitoring
Daily 250 m marine
mammal exclusion zone monitoring was undertaken under this Contract. No sighting of the Indo-Pacific humpback dolphin Sousa chinensis
(i.e. Chinese White Dolphin) was recorded in the reporting period during the
exclusion zone monitoring.
Marine bored
piling monitoring programme for dolphins (ie
Land-based Theodolite Tracking, Underwater Noise Monitoring and Acoustic Behavioural Monitoring)
was commenced on 3 March 2014 and completed on 25 April 2014. Data analysis was being undertaken for
the marine bored piling monitoring programme which will be presented in the
Final Monitoring Reports for the Land-based Theodolite Tracking and Underwater
Noise and Dolphin Acoustic Behavioural Monitoring.
The second
quarterly Coral Post-Translocation Monitoring was conducted on 16 April 2014
and the results were provided in the Second
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.
2.7
EM&A Site Inspection
Site
inspections were carried out on a weekly basis to monitor the implementation of
proper environmental pollution control and mitigation measures under the
Contract. Thirteen (13) site
inspections were carried out in the reporting quarter on 5, 12, 19, 26 March; 2,
9, 16, 23, 30 April; 7, 13, 21 and 29 May 2014.

Potential
environmental impacts arising from the above upcoming construction activities are
mainly associated with air quality, noise, marine water quality, marine ecology
and waste management issues.
Impact
monitoring for air quality, noise, marine water quality and marine ecology
(include dolphin monitoring and post-translocation coral monitoring) are
scheduled to continue for the next reporting period.
The monitoring
programme has been reviewed and was considered as adequate to cater for the
nature of works in progress.

Conclusions
and recommendations
This Second Quarterly
EM&A Report presents the findings of the EM&A activities undertaken
during the period from 1 March to 31 May 2014, in accordance with the Updated
EM&A Manual and the requirements of EP-354/2009/B.
Neither Action
Level nor Limit Level exceedances were observed for air quality, noise and
water quality impact monitoring in this reporting period.
A total of 31 groups of 103 Chinese
White Dolphin sightings were recorded
during the six sets
of surveys from March 2014 to May 2014. Whilst two Action 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.
Although the dolphins infrequently occurred along the alignment of TM-CLKL Southern
Connection Viaduct Section in the past and during the baseline monitoring
period, it is apparent that dolphin usage has been significantly reduced in NEL. It is critical to monitor the dolphin
usage in North Lantau region in the upcoming quarters, to determine whether the
dolphins are continuously affected by the various construction activities in
relation to the construction works of the Contract, and whether suitable
mitigation measure can be applied to improve the situation.
Environmental
site inspection was carried out thirteen (13) times in the reporting period. Recommendations on remedial actions were
given to the Contractor for the deficiencies identified during the site audits.
No summons/
prosecution were received during the reporting period.
The monitoring
programme has been reviewed and was considered as adequate to cater for the
nature of works in progress. Change
to the monitoring programme was thus not recommended at this stage. The monitoring programme will be
evaluated as appropriate in the next reporting period. The ET will keep track on the
construction works to confirm compliance of environmental requirements and the
proper implementation of all necessary mitigation measures.
