Future Key Issues
Potential
environmental impacts arising from the above upcoming construction activities
in the coming quarterly period are mainly associated with air quality, noise, marine
water quality, marine ecology and waste management issue.
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. Another application
for variation of environmental permit (VEP) (EP-354/2009/B) was granted on 28 January 2014.

The schedules
for water quality monitoring in the reporting quarter are provided in Appendix E. No impact water quality monitoring was
conducted on 9 and 16 September 2014 due to suspension of marine works and
adverse weather condition, respectively.
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 Eleventh to Thirteenth Monthly EM&A Report.
In this
reporting period, a total of Thirty-nine (37) monitoring events were undertaken
in which no Action or Limit Level exceedance were recorded during the reporting
quarter.
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 2.4. The co-ordinates of all transect lines
are shown in Table 2.11 below.

The action and
limit levels of dolphin impact monitoring are shown in Appendix D. The Event and Action plan is presented
in Appendix J.
The dolphin
monitoring schedules for the reporting period are shown in Appendix E.
A total of
892.88 km of survey effort was conducted, with 97.1% 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, 343.71 km and
549.17 km of survey effort were conducted in NEL and NWL survey areas respectively. The total survey effort conducted on
primary lines was 644.60 km, while the effort on secondary lines was 248.28
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 September to November 2014, a total of twenty-four
(24) groups of ninety-three (93) Chinese White Dolphins were sighted. All except four (4) dolphin sightings
were 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. In this
quarterly period, all dolphin groups were sighted in NWL, while none of them
were sighted in NEL. Summary table
of the dolphin sightings is shown in Appendix I.
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 September 2014 to November 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).
Another
comparison in dolphin distribution was made between the two quarterly periods
of autumn months in 2013 and 2014 was also made
Between
the two autumn periods, none of the dolphin sightings was made in NEL in autumn
2014, while there were two (2) sightings made in autumn 2013. Moreover, more dolphin sightings were
made in the middle and western portions of North Lantau waters in the autumn of
2013 than in the autumn of 2014.
Encounter
rates of Chinese White Dolphins deduced from the survey effort and on-effort
sighting data from the primary transect lines under favourable
conditions (Beaufort 3 or below) in the reporting period with the results
presented in Tables 2.12 and 2.13.

Daily
marine mammal exclusion zone monitoring was undertaken during the period of
marine works under this Contract. Passive
Acoustic Monitoring (PAM) was also implemented for the detection of marine
mammal when marine works were carried out outside the daylight hours under this
Contract. No sighting of the
Indo-Pacific humpback dolphin Sousa chinensis (i.e. Chinese White Dolphin) was recorded in
the monitoring period during the exclusion zone monitoring.
The Fourth Quarterly Post-Translocation Coral
Monitoring was conducted on 23 October 2014 and no exceedance of Action and
Limit Levels was recorded. The results were detailed in the Fourth Quarterly Post- Translocation Coral
Monitoring Report and were 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.
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, 10, 19, 25 and 30
September 2014; 8, 16, 23 and 30 October 2014; 5, 12, 20 and 27 November 2014.

Two (2) 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, there is no evidence
showing that the sources of impact directly related to the construction works under
this Contract that may have affected the dolphin usage in the NEL region. Investigation findings are detailed in Appendix L.

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.
This Fourth Quarterly
EM&A Report presents the findings of the EM&A activities undertaken
during the period from 1 September to 30 November 2014, in accordance with the
Updated EM&A Manual and the requirements of the Environmental Permit (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-four
(24) groups of ninety-three (93) Chinese White Dolphins were sighted during the
six sets of surveys from September 2014 to November 2014. Whilst two (2) Action Level exceedances
were recorded for the quarterly dolphin monitoring data between September and
November 2014, no unacceptable impact from the activities of this Contract on
Chinese White Dolphins was noticeable from the general observations. 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.
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.
