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 (VEP)

During this
reporting period, major marine dredging activities included dredging at Portions
N-C, seawall construction at Portions N-B and N-C, and reclamation filling at
Portions N-A and N-B. A closed grab
dredger was used and silt curtains (cage-type and single floating type) were
deployed during dredging works in accordance with the EP. The level of dredging activities was
within the working rate described in the EP and the approved EIA Report. In addition, reclamation filling was
undertaken between the 200 m of leading seawalls using filling materials
specified in the EP and the approved EIA Report with a single layer silt
curtain being deployed as a precautionary measure to reduce dispersion of
suspended solids. It is useful to
note that heavy marine traffic (not associated with the Project) was commonly
observed nearby the Project site and its vicinity.
Impact water
quality monitoring was conducted at all designated monitoring stations in the
reporting period under favourable weather
conditions. Monitoring results are
presented graphically in Appendix G [JY1] and
detailed impact water quality monitoring data were reported in the Eighth to Tenth Monthly EM&A Report.
In this
reporting period, a total of thirty-eight monitoring events were undertaken in
which no exceedances were recorded.
Summary of
Exceedances for Water Quality Impact Monitoring in this Reporting Quarter is
detailed in Table 2.17.
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.

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.
The impact
dolphin monitoring was carried out in the NEL and NWL along the line transect
as depicted in Figure 2.3. The co-ordinates of all transect lines
are shown in Table 2.8 below.

NWL survey areas, respectively. The
total survey effort conducted on primary and secondary lines were 647.96 km and
246.44 km, respectively. The survey
efforts are summarized in Appendix H.
A total of 28 groups of 96 Chinese
White Dolphin sightings were recorded
during the six sets
of surveys in this reporting quarter.
All except two sighting were made during on-effort search. Twenty on-effort sightings were made on
primary lines, while six other on-effort sightings were made on secondary
lines. During this reporting
quarter, almost all dolphin
groups were sighted in NWL, with the exception of one group of four dolphins
being sighted in NEL.
For the
detailed comparison of dolphin occurrence and usage of NEL and NWL survey area
between the impact phase and baseline phase monitoring, only the quarterly data
of June 2014 to August 2014 from the impact phase monitoring was used in the
present report to tally with the three-month period of baseline monitoring
(September 2011 to November 2011).
As the
baseline monitoring period was in the autumn season (September 2011 to November
2011) while the present monitoring period was in the summer season (June 2014
to August 2014), a direct comparison in dolphin distribution between the two
quarterly periods of summer months in 2013 and 2014 was also made to avoid the
potential bias in seasonal variation.
Between the two summer periods, none of the
dolphin sightings was made in NEL in summer 2014, while there were five
sightings made in summer 2013.
Moreover, more dolphin sightings were made in the middle and western
portions of North Lantau waters and to the north of the airport platform in
summer 2013 than in summer 2014.
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 the reporting quarter
with the results and comparison with baseline results present in Tables 2.9 and 2.10.

Whilst two
Action Level exceedances were observed for the quarterly dolphin monitoring
data between June 2014 and August 2014, no unacceptable impact from the construction
activities of this Contract was recorded from the general observations.[JY2]
Although the
dolphins infrequently occurred along the alignment of TM-CLKL Northern
Connection Sub-Sea Tunnel 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 HZMB-related works, and whether
suitable mitigation measure can be applied to revert the situation.
Daily 250 m marine mammal
exclusion zone monitoring was undertaken during the period of dredging
activities under this Contract. Passive Acoustic Monitoring (PAM) was
also implemented for the detection of marine mammal when marine works are
carried out outside the daylight hours during the reporting period. No
sighting of the Indo-Pacific humpback dolphin Sousa chinensis (i.e. Chinese White
Dolphin) was recorded during the reporting period during both day-time marine
mammal exclusion zone and passive acoustic 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 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.
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 3, 10, 18 and 25 June;
2, 9, 16, 23 and 30 July; 6, 13, 20 and 27 August 2014.
Key
observations during the site inspections in this reporting period are
summarized in Table 2.12.

For marine
water quality impact monitoring, a total of thirty-eight monitoring events were
undertaken in which no exceedances were recorded (Table 2.17).
In addition, the
construction impact on depth-averaged SS was assessed to compare 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 2.16),
thus no further action is required in accordance with the Updated EM&A
Manual.

Potential environmental
impacts arising from the above upcoming construction activities are mainly
associated with dust, marine water quality, marine ecology and waste management
issues.
Impact
monitoring for air quality, marine water quality and marine ecology (include
dolphin monitoring and post-translocation coral monitoring) are scheduled to
continue for the next reporting period.
This Third
Quarterly EM&A Report presents the findings of the EM&A activities
undertaken during the period from 1 June 2014 to 31 August 2014, in accordance
with the Updated EM&A Manual and the requirements of EP-354/2009/B.
Air quality
(including 1-hour TSP and 24-hour TSP), marine water quality, coral and dolphin
monitoring were carried out in the reporting period. No Action Level or Limit Level
exceedances for 1-hr TSP, and no Action Level or Limit Level exceedances for
24-hr TSP were recorded during the reporting period. No Action Level or Limit Level
exceedances were recorded in marine water quality impact monitoring during the
reporting period. No Action Level
or Limit Level exceedances were recorded in the post-translocation coral
monitoring in the reporting period.
Nevertheless, the Contractor was reminded to ensure that all dust
mitigation measures are provided at the construction sites and the proper
deployment of cage-type silt curtains at the dredging site.
A total of 28 groups of 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 construction activities of the TM-CLKL
Northern Connection Sub-sea Tunnel Section on Chinese White Dolphins was
noticeable from general observations.
Although the dolphins infrequently occurred along the alignment of TM-CLKL
Northern Connection Sub-Sea Tunnel 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.
Thirteen
weekly environmental site inspections were carried out in the reporting
period. Recommendations on remedial
actions provided for the deficiencies identified during the site audits were
properly implemented by the Contractor. No non-compliance event was
recorded during the reporting period.
No complaint/ enquiry was received during the reporting period.
No summons/
prosecution was 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.
