Breaches of Action and Limit Levels for Air Quality
No exceedance of Action and Limit Levels was recorded for
construction noise 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
During this
month of dolphin monitoring, 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.
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.
Daily
marine mammal exclusion zone monitoring was undertaken. No sighting of the Indo-Pacific humpback
dolphin Sousa chinensis
(i.e. Chinese White Dolphin) was recorded in April 2014 during the exclusion
zone monitoring.
Coral Monitoring
The Second
Quarterly Post-Translocation Coral Monitoring was conducted on 16 April 2014
and the results were detailed 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.
Environmental Complaints, Non-compliance & Summons
No 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 May 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-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.

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 of 8 groups
of 30 Chinese White Dolphin sightings were recorded
during the two sets
of surveys in April 2014. All
sightings were made in NWL during the two sets of surveys in April,
with no dolphin being sighted at all in NEL. Five of the eight 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
TM-CLKL Southern Connection Viaduct Section. 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 April 2014 with the results presented in Tables 2.12 and 2.13.

activities being undertaken. No sighting of Indo-Pacific humpback
dolphin Sousa chinensis
(i.e. Chinese White Dolphin) were recorded in April 2014 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
monitoring schedule for bored piling monitoring in April 2014 is presented in Appendix F.
The Second
Quarterly Post-Translocation Coral Monitoring was conducted on 16 April 2014
and the results were detailed 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.

Potential
environmental impacts arising from the above upcoming construction activities
in the next reporting month of May 2014 are mainly associated with dust, noise,
marine water quality, marine ecology and waste management issues.
This Sixth Monthly
EM&A Report presents the findings of the EM&A activities undertaken
during the period from 1 to 30 April 2014, in accordance with the Updated
EM&A Manual and the requirements of EP-354/2009/B.
A total of eight
(8) groups of thirty (30) dolphin sightings were recorded during the two sets of
surveys. All sightings were made in NWL during
the two sets of surveys in April, with no dolphin being sighted at all in NEL. During this reporting
period of dolphin monitoring, no unacceptable impact from the construction activities
of the TM-CLKL Southern Connection Viaduct Section on Chinese
White Dolphins was noticeable from general observations.
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 ET will
keep track on the construction works to confirm compliance of environmental
requirements and the proper implementation of all necessary mitigation measures.
