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-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. Another application
for variation of environmental permit (VEP) (EP-354/2009/B) was granted on 28 January 2014.
Under Contract No. HY/2012/07, Gammon

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/Limit 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. 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 (16) 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 water quality monitoring stations in
accordance with the Updated EM&A Manual (Figure 2.3; Table 2.8).

Results and Observations
Impact water
quality monitoring was conducted at all designated monitoring stations in the
reporting period. Monitoring
results are presented graphically in Appendix H and
detailed impact water quality monitoring results were reported in the Eighth to Tenth Monthly EM&A Report.
In this
reporting period, a total of Thirty-nine (39) monitoring events were undertaken
in which no 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 co-ordinates of all transect lines

in Appendix J.
2.4.6
Monitoring Schedule for the Reporting Period
The dolphin
monitoring schedules for the reporting period are shown in Appendix E.
2.4.7
Results & Observations
A total of 894.40
km of survey effort was collected, with 93.6% 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, 343.21 km and 551.19 km of survey effort were conducted in NEL
and NWL survey areas respectively. The
total survey effort conducted on primary lines was 647.96 km, while the effort
on secondary lines was 246.44 km.
Both survey efforts conducted on primary and secondary lines were
considered as on-effort survey data. The survey efforts are summarized in Appendix I.
During the six
sets of monitoring surveys from June to August 2014, a total of twenty eight (28)
groups of ninety six (96) Chinese White Dolphins were sighted. All except two (2) dolphin sightings
were made during on-effort search. Twenty
(20) on-effort sightings were made on primary lines, while another six (6)
on-effort sightings were made on secondary lines. In this quarterly period, almost all
dolphin groups were sighted in NWL, with the exception of one (1) group of four
(4) dolphins being sighted in NEL.
Summary table of the dolphin sightings is shown in Appendix I.

Whilst two (2)
Action Level exceedances (one Action Level exceedance for Northeast Lantau
cluster; one Action Level exceedance for Northwest Lantau social cluster) and
no Limit Level exceedance were observed for the quarterly dolphin monitoring
data between June and August 2014. During
this quarter of dolphin monitoring, no unacceptable impact from the activities
of this Contract on Chinese White Dolphins was noticeable 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.
2.5
Post-Translocation
Coral Monitoring
The third quarterly
Coral Post-Translocation Monitoring was conducted on 24 July 2014 and the results
were provided in the Third Quarterly
Post-Translocation Coral Monitoring Report submitted under a separate cover. 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.
2.6
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 4, 11, 19 and 25 June
2014; 2, 10, 16, 24 and 31 July 2014; 6, 14, 21 and 27 August 2014.

In response to the site audit findings,
the Contractors carried out corrective actions.
A summary of the Implementation Schedule
of Environmental Mitigation Measures (EMIS) is presented in Appendix
C. The necessary mitigation measures were
implemented properly for this Contract.
Results
for 1-hour TSP, 24-hour TSP, construction noise and impact water quality
monitoring complied with the Action/ Limit levels in the reporting period.
The
construction impact on depth-averaged SS was assessed by comparing the
quarterly mean values of depth-averaged SS with the relevant ambient mean
values. Results showed that the
quarterly mean values of depth-averaged SS at all monitoring stations are well
below the ambient mean values (Table 2.18),
thus no further action is required in accordance with the Updated EM&A
Manual.

Two Action
Level exceedances were recorded for impact dolphin monitoring in this reporting
quarter. Following the review of
the monitoring data and marine works details as per the procedure stipulated in
the Event and Action Plan of the Updated EM&A Manual, the recorded
exceedance was considered to be due to natural variation of dolphin ranging
pattern. Investigation findings
were detailed in Appendix L.
The
Environmental Complaint Handling Procedure is provided in Figure 2.5.
One
(1) complaint was referred by EPD on 23 June 2014 regarding to the discharge of
muddy water from Site Access 9A to the nearby storm drains. Complaint
investigation was conducted on 25 June 2014 and the interim report was
submitted to EPD on 4 July 2014.
The complaint was considered to be not related to the Contract and it
was subsequently closed upon further investigation on 30 July 2014. However, the Contractor was reminded to
implement the on-site precautionary measures appropriately for handling the
waste water, if any, during rainy season. The complaint investigation findings are
detailed in Appendix N of the Ninth Monthly EM&A Report.
Statistics
on complaint, notification of summon of successful prosecution are summarized
in Appendix L.

3.2
Key Issues for the Coming Quarter
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 Third Quarterly
EM&A Report presents the findings of the EM&A activities undertaken
during the period from 1 June to 31 August 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, water
quality impact monitoring and post-translocation coral monitoring in this
reporting period.
A total of twenty
eight (28) groups of ninety six (96) Chinese White Dolphin sightings were
recorded during the six sets of surveys from June 2014 to August 2014. Whilst two Action Level exceedances were
recorded for the quarterly dolphin monitoring data between June and August 2014,
no unacceptable impact from the activities of this Contract on Chinese White
Dolphins was noticeable 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.
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.
One
(1) environmental complaint regarding the discharge of muddy water and soil from
Site Access 9A to the nearby storm drains was received on 23 June 2014 and the
interim complaint investigation was undertaken on 25 June 2014. The complaint was considered to be not
related to the Contract and it was subsequently closed upon further
investigation on 30 July 2014.
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.
